A Summary of Typical New Constructi on Major Milestones and Message Reporting Requirements B General Time Lines of Key Events C Glossary of Terms 1.1 PURPOSE. Volume I of this manual summarizes maintenance related information for all units of the Fleet during Ship construction and through the completion of Post Shakedown Availability (PSA). The time span is from initial crew man-up to departure from the PSA facility. 1.2 SCOPE. a. New Construction ships require a succe ssion of inspections and tests followed by a series of underway trials. The philosophy and sequencing of these inspections, tests, and trials are set forth in references (a), (b) and (c) and are graphically represented in Appendices A and B of this chapter. This Volume provides information, guidance, policies and procedures for maintenance related topics during the Ship's construction period. Reference (d) must be used in conjunction with the Joint Fleet Maintenance Manual (JFMM) to establish an effective maintenance program. The requirements of this manual do not supersede or take precedence over directives issued by higher authority. Where conflicts exist with previously issued Type Commander (TYCOM) letters and transmittals, this manual takes precedence. Conflicts should be reported to the applicable TYCOM. b. The development of this and subsequent volumes to the JFMM has required the study of numerous reference documents, many of which are referenced as source or governing documents in specific chapters. The Foreword of this Manual contains a Master Listing of all the references called out in the JFMM. These references are arranged in an alphanumeric sequence to facilitate the ordering of documentation to support the use of the JFMM. References used in specific chapters are called out at the beginning of that chapter.

APPENDIX C GLOSSARY OF TERMS TERM DEFINITION Alpha Trial Builder’s Propulsion Trial; Acceptance Trial for SSN, SSBN, SSGN Propulsion Plant; Initial Tightness Dive (SSN, SSBN, SSGN); Dive to Maximum Authorized Depth (Selected SSN platforms). Acceptance Trials (AT) Trials and material inspections conducted underway by the INSURV Board for ships constructed in a private industrial activity to determine suitability for acceptance of a ship by the Navy. Accepting Authority The officer designated by the Chief of Naval Operations (CNO) to accept a vessel for the Navy, normally NAVSEA. Bravo Trial Normally the initial Dive to Test Depth; Noise Trial (SSN , SSBN, SSGN); Strategic Weapons System Missile Testing (SSBN); Weapons testing (Surface Combatants). Builder's Trials (BT) Evaluation trials and in spections conducted underway by the builder to assure the builder and the Navy that the ship is, or will be, ready for Acceptance Trials. These trials should be a comprehensive test of all ship’s equipment and be similar in scope to Acceptance Trials. For nuclear powered surface ships, this is the Acceptance Trial for the Nuclear Propulsion plant. Charlie Trial Combat Systems and retesting (SSN , SSBN, SSGN); Acceptance Trials (DDG). Combined Trials (CT) Combined Trials are a combination of an Acceptance Trial with a Final Contract Trial. The INSURV Board normally conducts Combined Trials for nuclear powered submarines. Common Assessment Procedures Common assessment procedures are assessments that, to the maximum extent possible, are common across platforms and serve all users for assessments, inspections and certifications. Common assessment procedures are RCM applicable and effective maintenance procedures that can be properly and consistently executed. They deliver accurate assessment and measurement of, determine and document discrepancies to, and specify repairs required to restore satisfactory material condition. Common assessment procedures satisfy the needs of work definition, inspections and certifications in a common document used both across ship classes and by all activities. The two

p. 22

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-1C-2 APPENDIX C types of commonality invoked are common across functional use and common across platforms with similar systems and equipment. Deep Dive The first dive to maximum operating depth. This depth will not necessarily coincide with the design test depth of the hull. See definition of Maximum Operating Depth. Delivery The date the Navy accepts the ship from the shipbuilder. This requires a recommendation from the INSURV Board to accept or deliver the ship. Delivery of the ship is based on Acceptance Trials and satisfactory correction or resolution of deficiencies. Dock Trial Dock Trials are those ship tria ls conducted at the Industrial Activity to determine the ability of the ship, from a material standpoint, to conduct Sea Trials safely. Executive Agent A term used in Department of Defense and Service regulations to indicate a delegation of authority by a superior to a subordinate to act on behalf of the superior. An agreement between equals does not create an executive agent. Fast Cruise A period immediately prior to underway trials during which Ship's Force operates the ship for dockside training. Fast Cruise must, as far as is practical, simulate at-sea operating conditions. Final Contract Trials (FCT) Trials that are conducted prior to the end of the guarantee period to determine if there are any defects, failures, or deterioration other than that due to normal wear and tear. Fleet Introduction Team (FIT) A team of personnel assembled to support a pre-commissioning crew by monitoring progress of construction and coordinating training and facilities. They provide administrative support in all facets of new construction. Group Normally that first 1-Star organization or Command above the Squadron before to TYCOM. Guarantee Material Inspection (GMI) A material inspection, conducted inport prior to Post Shakedown Availability (PSA) by a Trial Board prior to the end of the guarantee period when CNO has authorized a Combined Trial to determine if contractor responsible equipment has operated satisfactorily during the guarantee period. It must include the opening and inspection of equipment designated by the Board together with the operation and visual inspection of equipment and the review of material maintenance records. Guarantee Period The period of time imme diately following preliminary acceptance

p. 23

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-1C-3 APPENDIX C (New Construction) (delivery), normally eigh t or nine months (six months for nuclear powered ships), for which the industrial activity is responsible for the correction of deficiencies. Guarantee Period (PSA) The guarantee period following PSA varies with the type of contract. Historically, a “cost plus” type contract has had a guarantee period of six months and a “fixed price” type contract a period of 90 days. The Supervising Authority will advise at the time of PSA the guarantee that applies. In-Service Nuclear powered ships are as signed an active status of In-Service approximately two to four weeks (two to four months for aircraft carriers) prior to the commencement of Sea Trials and maintain this status until commissioning. Industrial Activity The activity responsible for accomplishing construction or repair of ships whether private or public. This includes Naval shipyards, private shipyards, shipbuilders, vendors, Naval Aviation Depots, Naval Ship Repair Facilities, and other Naval Repair or Technical Activities (Naval Underwater Weapons Center, Naval Ships Weapons Center, etc.). Initial Dive For purposes of seawater va lve and system testing, as defined in NAVSEAINST C9094.2, the first dive to a depth not previously reached during the trials. Initial Tightness Dive First submerge nce (a submarine's Alpha Trial). INSURV Prior to the acceptance and deliv ery of a new ship, whether built by a private or a naval industrial activity, all machinery, electronics and weapons systems installed must be subjected to acceptance trials to determine that the installations are capable of meeting performance specifications. Depending upon your platform, these trials are referred to as either Acceptance Trials, Combined Trials or INSURV. This independent verification of the ship’s readiness for acceptance and recommendation for fleet introduction is the responsibility of the President, Board of Inspection and Survey. Lead Maintenance Activity The single activity responsible for integrating all maintenance and modernization on U.S. Naval ships during any type of availability. Maximum Operating Depth (Also Maximum Authorized Operating Depth) The depth to the keel for a particular submarine which is authorized by Commander Submarine Forces Atlantic or Commander Submarine Forces Pacific upon the recommendation of NAVSEA, as the depth not to be exceeded in operations. This depth is normally the Test Depth but may be reduced in specific cases. The depth authorized may be less than, but in no case exceed, the depth recommended by NAVSEA.

(2) Participate in an underway period of at least five days duration approximately six months prior to the final phase of Crew Certification. The purpose of this ride is to re-familiarize the PCO with those functions unique to being underway so as to ensure the safe conduct of his own initial Sea Trials and shakedown. This underway period also allows the PCO to validate his crew’s training program. This underway period should be on a ship, preferably of the same class, which is concentrating on basic ship or submarine operations, such as Selected Refresher Training or Independent Ship Exercise (ISE), so the PCO can witness such evolutions as: coming to periscope depth, snorkeling, ventilating, casualty training, etc. If the new construction schedule has 10-12 weeks between Power Range testing and the final phase of Crew Certification, the PCO should go to sea approximately two months before initial criticality. The intent is for the PCO to go to sea after having been in the Industrial Activity for a fair amount of time (normally one year or more), but with sufficient time remaining to improve his own training program if necessary. During these underway periods, the PCO should spend time on the bridge and also observe piloting and navigation.

The PCO and crew will monitor the ship’s construction, prepare ship’s directives, regulations and administrative programs, and observe and demonstrate the operation of installed systems to ensure the ship is safe and habitable prior to commissioning. The shipyard period is an opportunity for the crew to familiarize themselves with the ship. The ship will be required to complete various certifications leading up to introduction into the fleet. This section provides some insight into the administrative requirements and personnel related issues associated with the initial man-up. 2.9.1 Initial Man-up. New construction ships are manned based on a Crew Scheduling and Phasing Plan. Dependent upon the platform type, crew manning is accomplished in two, three, four or as many as eight increments. The quantitative and qualitative requirements of these increments are based on the platform type, test and construction schedule. The objectives of the Crew Scheduling and Phasing Plan are to: a. Ensure adequacy of schooling for personnel assigned. b. Ensure appropriate course convening dates. c. Ensure there are no conflicts or redunda ncies between Navy and contractor courses. d. Ensure sufficient training for antic ipated maintenance and operating skill requirements. e. Ensure the optimization of training oppor tunities for personnel in the pipeline enroute to the ship. A senior crew member from the first increment must be assigned with the responsibility of tracking and reviewing manning issues. For some ships, the Navy Shipbuilding Program Manager has provided support contractors to assist either partially or entirely in the management of the Crew Scheduling and Phasing Plan. Regardless of the class or type of ship, the initial increment of personnel must quickly organize. If a detachment concept is used, Appendix O of this chapter provides a basic listing of requirements that the first increment of personnel should be pursuing. Appendix P of this chapter provides similar information for the non-detachment approach. 2.9.2 Training. 2.9.2.1 Shipboard Training. The Industrial Activity presents a unique environment with special circumstances not routinely encountered by operating forces. The incremental assignment of personnel to PCUs and the pace of new construction demands a comprehensive training strategy. A well-established training program is the key to the ship being ready for introduction into the Fleet. Consistent with the objectives of a shipboard training program, the TYCOM training manuals and references (j), (o) and (p), a new construction training program will ensure that: a. (Nuclear Powered Ships only) The qua lification of all Engineering and Reactor Department personnel in strict accordance with reference (q). Included is the CO’s responsibility to personally conduct an RSE of each key propulsion plant watch stander. b. Personnel are trained in any special Quality Assurance (QA) procedures that may be used during the construction period.

p. 47

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-2-21 c. Personnel assigned are knowledgeable of the platform, system and equipment installations and operation of installed equipment. d. Watch stander qualifications support a watch section of fully or provisionally qualified personnel for all scheduled events. e. Training designated for assigned pers onnel supports the platform and equipment configuration. f. Intensified special trai ning is provided to support: (1) Cold Operations. (2) Hot Operations. (3) RSE. (4) LOA. (5) Criticality or Power Range Testing. (6) Combat Systems Installation Certification. (7) Crew Certification. (8) Fast Cruise and Sea Trials. (9) Piloting Party or Navigation Detail. (10) Damage Control Team. (11) Fire Fighting Team. (12) Tactical Team. (13) Special details. g. All billets requiring specific Navy Enlisted Classifications are filled. h. Established Naval Schools and Trainers ar e used to the maximum extent possible. i. Factory training on systems and eq uipment for which Naval Schools are not established is provided. j. Special training following TYCOM directiv es is provided for provisional certification to load, handle, stow and maintain a weapons load-out specific to the class of ship. k. Weapons or Combat Systems training is sufficient to enable the Weapons or Combat Systems Department to operate its systems while complying with existing safety rules, technical directives and governing operating procedures issued by the CNO, the Defense Nuclear Agency, NAVSEA, Space and Naval Warfare Systems Command, the TYCOM or other commands as applicable. l. Industrial Activity or co ntractor familiarization training courses are monitored for content and value. Provide supplemental instruction where necessary and inform the Supervising Authority and Navy Shipbuilding Program Manager of significant problems or shortfalls.

p. 48

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-2-22 m. The enlisted training program is started as soon as the Leading Petty Officers for the major divisions arrive. The Officers and senior enlisted personnel will develop the content and scope of the training programs for implementation with the arrival of the first large increment of enlisted personnel. n. Aircraft Launch and Recovery Equipm ent Maintenance Program training must be conducted per reference (r). 2.9.2.2 Industrial Activity Training. The Industrial Activity or FIT will provide familiarization training following the shipbuilding contract on ship’s characteristics and systems. This training generally is not sufficient for “System Expert” qualification, but will provide an excellent opportunity for School of the Boat or Ship, and at the same time provide an opportunity for Divisional Training Petty Officers to develop a more detailed and in depth training program. In most cases, the Industrial Activity will allow the ship to control the scheduling of topics. 2.9.2.3 Training Support Center. Surface ships utilizing the Pre-Commissioning Detachment Concept at a Training Support Center (TSC), either in Norfolk, VA or San Diego, CA, are provided with an outstanding opportunity to ensure pipeline training is obtained. This concept also provides for the easy access to many of the basic courses such as firefighting, damage control, Repair Parts Petty Officer training, Drug and Alcohol Program Advisors, Component Change Control, etc., which are needed to ensure assigned personnel can effectively function as a ship’s crew upon delivery. For ships not utilizing the TSC Detachment Concept, such as submarines, an individual should be assigned to monitor and track training and manning issues as they develop. 2.9.3 Ship’s Qualification Program. The implementation and operation of the Ship’s Qualification or Personnel Qualification Standard (PQS) should ensure a logical process for training Ship’s Force for watch standing and ship’s qualification. TYCOM instructions that cover Ship’s Qualification or PQS requirements are found in references (j), (o) and (p). The department organization manual should establish prerequisites for watch stander qualification. Qualification goals should be established and the program should support completion of goals within each division. Fleet wide training and qualification goals are: a. Underway Watchbills; 3 Section Enliste d, 4 Section Officer or Chief Petty Officer. b. Inport Watchbills; 4 Section Enlisted, 5 S ection Officer or Chief Petty Officer (6 Section for all personnel on Aircraft Carriers). 2.9.4 Deficiency Identification and Correction. The establishment of procedures by which Ship’s Force reports and tracks the correction of deficiencies cannot be overstressed. The Supervising Authority relies heavily upon PCU involvement to augment their efforts. Inspections of systems, equipment and spaces by PCU personnel are extremely important in the identification of unsatisfactory work and material deficiencies. Each shipbuilder and associated Supervising Authority have their own established system for tracking shipbuilder responsible deficiencies. Those deficiencies which are not corrected during the construction cycle will be submitted to the INSURV Board just prior to FCT, AT or CT (the type of trial dependent on platform). These deficiencies, depending on their seriousness, may impact a ship’s delivery to the Navy. Deficiencies cited must either be resolved, corrected or waived by the Navy Shipbuilding Program Manager.

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-2-23 2.9.5 Establishment of Engineering and Reactor Department. This paragraph addresses the Engineering or Reactor Department establishment and tasks which are to be accomplished during the pre-commissioning phase of new construction. The tasks defined in this section incorporate experience gained and lessons learned from previously completed ships. The objective is to provide guidance which will assist in the ship’s readiness, from an Engineering or Reactor Department standpoint, to successfully complete contract milestones and to prepare for fleet introduction. 2.9.5.1 Requirements. The PCU should monitor and report on the ship’s construction progress to the PCO, and dependent upon platform, conduct, witness and participate in the ship’s dockside and at-sea testing, attend periodic documentation reviews, assessments, and validations, and provide recommendations regarding manpower, training, watch standing and related shipboard engineering requirements. Tasks and responsibilities include items discussed in the following paragraphs. 2.9.5.2 Shipboard Inspections. Shipboard inspections by the ship’s Engineering, Reactor Department and cognizant Supervising Authority personnel are necessary during the ship construction phase. There is no precise pattern or timetable for these inspections, but they should be thorough and conducted frequently. Ship’s Force personnel need to become familiar with the contract specifications and system drawings. This will ensure the prompt identification, and documenting, of discrepancies discovered when comparing “as built” conditions to the actual specification. 2.9.5.3 Personnel Qualification Standards. Theoretical portions of PQS should be implemented during the training pipeline at the specific Training Centers and at the TSCs using available technical manuals and training material. Ship-wide PQS should be implemented prior to the arrival of the final crew increment at the shipbuilder’s yard. The ship’s Engineer Officer should establish interim watch qualifications to set the training goals for Engineering and Reactor Department personnel as they arrive at the Industrial Activity. Additionally, PQS sign-off authority should be specified in writing by the ship’s Engineer Officer, in order to ensure that the provisional qualifications and sign-off procedures function smoothly. 2.9.5.4 Outfitting Support (as applicable). The PCU must ensure that engineering spaces are completely outfitted. Routine progress inspections must be made in this area, and the PCU will participate in completing Compartment Completion Inspection Reports. It is important that personnel involved with Compartment Completion Inspection Reports are fully aware of all implemented Engineering Change Proposals and Engineering Change Notices to ascertain that outfitting materials and Operating Space Items (OSI) support the ship as revised by Engineering Change Proposals and Engineering Change Notices. Configuration Change Requests must be drafted with full recognition of the guidance contained in both the General Specifications for Building Naval Vessels and the specific Class Building Specifications. 2.9.5.5 Operational Sequencing System (Surface Force Ships and Aircraft Carriers only). The Operational Sequencing Systems (OSS) (Engineering Operational Sequencing System (EOSS), Sewage Disposal Operational Sequencing System, etc.) establish the operational procedures for various shipboard equipment, including applicable Casualty Control procedures.

This chapter addresses the major evolutions confronting the crew from initial man-up through Dock Trials, Fast Cruise and the commencement of Sea Trials. 3.2 SHIPBUILDER’S TEST PROGRAM. Throughout the building phase, the Shipbuilder is responsible for the testing and certification of installed equipment and systems. Reference (a) establishes the Test and Evaluation policy for all phases of a ship’s life cycle. This guide contains information concerning the documentation and procedural requirements for a ship’s Acquisition, Test and Evaluation Program. Reference (a), in conjunction with the Navy Shipbuilding Program Manager’s prepared System Acquisition, Test and Evaluation Handbooks, provides familiarization and an understanding of the total Ship Test Program. 3.3 INSPECTIONS, CERTIFICATIONS AND ASSISTS. There are numerous inspections and certifications associated with new construction. Reference (b), which can be obtained from the Supervising Authority, identifies all the certification requirements which have been approved for accomplishment during surface ship industrial periods. The following paragraphs deal with generic inspections or platform unique certifications. 3.3.1 Arrival Assist.

p. 131

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-3 a. Purpose. To determine that adequate plans have been developed and implemented to support the requirements of Ship’s Force training, administration and testing during new construction and to evaluate the ship’s ability to conduct various evolutions. b. Conduct. The arrival assist visit may be c onducted as a single visit or as a series of visits. Appendix A of this chapter provides sample areas to be reviewed during the arrival assist visit. c. Scheduling. The arrival assist should be scheduled for accomplishment within a two- month period following the arrival of the first crew increment. d. Reports. Formal reports are not require d. However, the Immediate Superior in Command (ISIC) should inform the Type Commander (TYCOM) in the event that progress in preparations is evaluated as unsatisfactory. 3.3.2 Periodic Monitoring, Inspections and Visits. a. Purpose. (1) To provide ships in new construc tion with training and administrative assistance as required by references (c) and (d). The focus will be to improve Ship’s Force involvement with the construction process, maintenance and training tasks. Visits of this nature are defined as Tech Assists. (2) To evaluate the effectiveness of the ship’s administration and training policies. Inspections of this nature are defined as “Work-ups” and normally require the addition of at least two officers to the inspection team. (3) To conduct spot checks to monitor progr ess in specific material, administrative and training areas. Visits of this nature are defined as Monitoring Visits. b. Conduct. The extent, type, and freque ncy of periodic monitoring inspections and visits should be determined by the ISIC. Submarine monitoring inspections may be combined with those required by reference (e). The initial inspection should be broad in scope in order to apprise the ISIC of the adequacy of the ship’s performance and progress. c. Scheduling. The initial inspection shoul d be conducted within a 45-day time period after the arrival inspection. The initial visit will indicate the frequency and scope of subsequent Tech Assists and Monitoring Visits. Some inspections should be conducted on an unannounced basis. In general, any required Work-ups should be scheduled in advance of Key Events. All inspections should be scheduled to minimize interference with industrial activity and Ship’s Force work. d. Reports. Formal reports are not require d. However, the ISIC should advise the TYCOM of situations where the completion of Key Events is in jeopardy due to a lack of progress in any of the subject areas identified in Appendix B of this chapter. e. Inspection Areas. Initial inspections nor mally examine the effectiveness of Ship’s Force follow-up actions as a result of the arrival assist. Subsequent inspections and visits should review the areas designated in Appendix B of this chapter as appropriate. 3.3.3 Pre-Reactor Safeguard Examination (Nuclear Powered Ships only).

p. 132

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-4 a. Purpose. To evaluate the readiness of the Engineering or Reactor Department to undergo a Reactor Safeguard Examination (RSE) by representatives of Naval Sea Systems Command Nuclear Propulsion Directorate (NAVSEA 08). Appendix C of this chapter provides a sample Pre-RSE Notice which should be tailored to fit your specific platform. b. Conduct. The Pre-RSE performed by the ISIC with TYCOM assistance is not intended to duplicate the inspections for which readiness is being evaluated. It is prudent, however, to use an inspection plan similar to that employed by NAVSEA 08. Normally the crew’s readiness can be assessed within two days using such a plan. The Supervising Authority will arrange for minimum industrial activity work interference during this inspection. c. Scheduling. The ISIC must conduct a Pre-RSE within six weeks of intended criticality. The Pre-RSE will be scheduled such that the qualification program and material condition of the ship are sufficiently complete to allow for a thorough inspection, but early enough to allow time for the correction of identified deficiencies prior to criticality. The TYCOM should be advised approximately two months prior to the tentative date and confirmed dates should be established approximately one month prior to the inspection. d. Composition of the Inspection Team. The Pre-RSE Inspection Team should consist of: (1) A nuclear trained member of the IS IC Staff, usually the Deputy Commander for Readiness or Training. (2) A qualified nuclear engineer with experience in the billet. (3) A nuclear trained officer from th e TYCOM Staff. Arrangements for the participation of TYCOM Staff members should be initiated by the ISIC at least one month prior to the anticipated inspection date. (4) The Prospective Commanding Officer (P CO) of the next local ship in a new construction status. (5) The TYCOM industrial activity representative. e. Reports. The Senior Inspector should provi de the ship with an informal report of the findings with a copy to the ISIC and TYCOM. f. Inspection Areas. The Pre-RSE should, as a minimum, encompass the following: (1) An administrative review. (2) Observation of basic drills and evol utions not requiring reactor operation or special conditions. (3) Personnel interviews and written tests. (4) Material inspection. 3.3.4 Crew Certification. Crew certification is required for new construction ships. Depending upon the platform and TYCOM policy, crew certification will be accomplished in two, three or four phases.

p. 133

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-5 a. Purpose. Initial phases determine the stat e of readiness and training of Ship’s Force, particularly in the areas of watchstander qualifications, damage control readiness, status of operational and emergency bills, onboard supply of essential technical manuals and general operational knowledge. Later phases are structured to certify that the state of crew training is satisfactory for at-sea operations. b. Scope. Certifications for submarines a nd surface ships will be conducted using the guidance of the applicable TYCOM training manual, references (f), (g), and (h). Reference (i) provides additional direction for aircraft carriers. 3.3.5 Sonar Certification (Applicable Surface Force Ships and Submarines). Sonar certification for surface force ships is accomplished per reference (b). Submarine sonar certification is accomplished per reference (h), during a designated Sea Trial just prior to the Combined Trial. Sonar certification is a prerequisite for Antisubmarine Warfare certification on surface ships and the Weapons and Tactical Readiness Evaluation on submarines. 3.3.6 Aviation Facility Certification (Air Capable Ships only). Reference (j) requires that all aviation facilities aboard naval ships which operate aircraft be formally inspected and certified adequate and safe for flight operations. It further directs, as implemented by references (k) and (l), that Commander, U.S. Pacific Fleet (COMPACFLT) and Commander, U. S. Fleet Forces (COMUSFLTFORCOM) will establish responsibilities and procedures for mandatory certification of all ships with aviation facilities. Reference (j) also directs the Chief of Naval Operations (CNO) to establish responsibilities and procedures for mandatory certification of all ships’ aviation facilities, provide for certification inspection teams and issue approved standards for certification. Naval Air Systems Command (NAVAIR) has overall responsibility for certification of aviation facilities and equipment in Naval ships. Aviation facility and equipment certification is a procedure which verifies and documents that the aviation facilities and equipment aboard ships are properly installed, operational, and adequate for the safe conduct of aircraft operations. Details for certifications can be found in reference (m), and in TYCOM specific instructions such as reference (n). a. Management Structure. (1) The Navy Shipbuilding Program Manage r is responsible for budgeting for the certification of ships involved in construction and modernization programs. (2) Naval Air Warfare Center (NAVAI RWARCEN) administers the aviation facilities and equipment certification programs and will establish test programs and procedures for each aviation facility and equipment component. b. Certification Procedures. (1) Requests. Submit requests for certification directly to NAVAIRWARCEN. The ship’s TYCOM will be advised of all requests for equipment and facility certification. Individual ships desiring certification inspections should submit requests via their TYCOM to ensure optimum scheduling of the certification team. Automatic Carrier Landing System certification requests will be submitted per reference (o). (2) Inspection and Testing. The ship’s aviation facilities and equipment will be inspected and tested by a team coordinated by a NAVAIRWARCEN

p. 134

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-6 representative. Upon completion, the NAVAIRWARCEN team coordinator will, (via message to NAWC, the TYCOM, and other appropriate commands) make a recommendation to either grant, rescind, or withhold certification. This recommendation is to be predicated upon all aviation facility systems or equipment being properly installed, configured, operational, and maintained as prescribed by applicable technical manuals or directives. The message will also specify the ship’s current certification status, including deficiencies that preclude full certification for the operational capabilities specified by the CNO. (3) Certification. NAVAIR or NAVAIRWA RCEN grants or rescinds certification via message after review of the recommendation from the NAVAIRWARCEN team coordinator and any other information that may be available. The certification message will be addressed to the TYCOM and other appropriate commands. It will specify the ship’s present aviation status, including any corrections that must be accomplished to achieve full certification for the operational capabilities specified by the CNO. Certifications granted will remain in effect until such time that major equipment modifications or alterations are accomplished or until the next overhaul (not to exceed two years on Air Capable Ships and Amphibious Assault Ships unless rescinded by NAVAIR or NAVAIRWARCEN. c. Technical Publications. A listing of technical publications required for Air Certification can be obtained from the TYCOM. References (b) and (m) list specific certifications required for aviation platforms. 3.3.7 Distressed Submarine and Salvage Inspection (Submarines only). a. Purpose. To determine the readiness of submarine rescue and salvage equipment. b. Conduct. Distressed Submarine and Salvage Inspections will be conducted following the direction of volume IV, chapter 18 of this manual. 3.3.8 NAVSEA Calibration Activity or Aircraft Intermediate Maintenance Department Calibration Laboratory Initial Certification (Submarines, Aircraft Carriers and Surfaces Forces, as appropriate). a. Purpose. To verify the NAVSEA or NAVAIR Designated Command has in place the necessary documentation, facilities, equipment and trained personnel to support calibrations of Test, Measurement and Diagnostic Equipment (TMDE) as specified in references (p), (q) and (r). b. Conduct. Initial cert ification is conducted by the NAVSEA or NAVAIR Metrology and Calibration (METCAL) Technical Representatives per the requirements of references (r) and (s). NAVSEA METCAL Technical Representatives are the NAVSEA METCAL Quality Manager and NAVSEA METCAL Engineering Agent. c. Scheduling. Initial certification s hould be accomplished after approval of Establishment of Field Calibration Activity Request and prior to or concurrent with delivery. Coordination between the TYCOM METCAL Point of Contact, METCAL Technical Representative, the Navy Shipbuilding’s Program Manager and Ship’s

p. 135

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-7 Calibration Coordinator is required to insure all participants can support the certification date and that all required TMDE is available. d. Reports. Reports will be per the requirem ents of reference (r) and submitted by letter to the applicable TYCOM and Commanding Officer (CO). e. Additional information concerning calibra tion can be found in Volume VI, Chapter 9 of this manual. 3.3.9 National Policy on the Control of Compromising Emanations Inspection. a. Reference (t) published the Navy’s implementation of the National Policy on the Control of Compromising Emanations (TEMPEST). Reference (u) provides installation criteria for shipboard secure electrical information processing systems. b. All ships are considered to be operating under an “acceptable risk” category until such time as they have been certified to meet National Policy. Two types of inspections are conducted to certify ships: (1) Instrumented TEMPEST Survey. The Instrumented TEMPEST Survey is a comprehensive inspection which will only be done on selected ships to certify the ship class. (2) Visual TEMPEST Inspection (VTI). The VTI is a less comprehensive inspection to certify compliance with class and CNO standards. VTIs can be conducted by Regional Maintenance Centers (RMC), industrial activities and Navy Command, Control, and Ocean Surveillance Center Naval In-service Engineering. c. A VTI will be accomplished on all new construction ships. This inspection will be scheduled upon the completion of the installation of all Radio Room or secure electrical information processing equipment. In addition, a TEMPEST file needs to be established to include all actions pertaining to installations, modifications or alterations to secure electrical information processing equipment or centers. The specific information to be retained is identified in reference (t). 3.3.10 Diesel Inspection. a. Purpose. To validate and certify engine alignment, foundation integrity, engine frame integrity, shimming and stressing requirements, hold down bolts, blower operation and engine performance. b. Conduct. Diesel inspections will be c onducted per Volume IV, Chapter 4 of this manual. 3.3.11 Habitability Inspection. Navy ships are built to meet habitability standards for berthing areas, messing areas, water closets, laundry and barber facilities as set forth in reference (v). Prior to certifying readiness for In-Service, the ISIC will conduct a Habitability Inspection to determine that the ship is materially ready for the crew to move aboard. The results of the Habitability Inspection will be reported to the TYCOM by message (see Volume I, Chapter 2, Appendix A4 of this manual for sample message). a. The Habitability Inspection for submarines is conducted two to four weeks prior to certifying the ship’s readiness for In-Service, two to four months prior to this

p. 136

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-8 certification for aircraft carriers and just prior to delivery and crew move aboard for all others. b. Compartment Surveillance Guide. Appendi x D of this chapter has been included to serve as a guide when preparing for the Habitability Inspection and In-Service. Appendix E of this chapter is a sample checklist which can be tailored to any platform. 3.3.12 Requirements for In-Service. Assigned Ship’s Force constitutes the only group of personnel authorized to operate naval nuclear powered ships during dockside testing and Sea Trials. Because of this requirement, references (c) and (d) specify that nuclear powered ships in construction are assigned an active status of In-Service prior to commencement of the first Sea Trial (two to four weeks for submarines, two to four months for aircraft carriers) and retains that status until delivery of the ship. To support this event, the contractor is required to make the ship available to the Navy for a period of two days for a Habitability Inspection two to four weeks prior to In-Service. At In-Service, the responsibility for, and custody of, fissionable materials is transferred from the Supervising Authority to the Officer in Charge (OIC) of the ship. The PCO becomes the OIC of the ship and continues in this capacity until Commissioning at which time the OIC becomes the CO. a. Responsibilities for Safety of the Ship. Placing the ship In-Service has an impact upon the established responsibilities for safety of the ship. (1) Prior to In-Service, or Delivery fo r Surface Ships, the industrial activity’s responsibilities for the safety of the ship are all inclusive. The Supervising Authority is responsible for monitoring the industrial activity’s safety and fire protection program. (2) At In-Service the PCO assumes the duties of OIC and the responsibility for the safety of the ship. Reference (w) states that the OIC of a ship In-Service has the same responsibilities for the safety of the ship as a CO of a commissioned ship. b. Division of Responsibility. In order to es tablish clear lines of responsibility at In- Service and to eliminate unnecessary duplication of effort, the following will apply: (1) Ship’s Force. At In-Service, Ship’s Force must have operational control of all ship’s systems required to maintain ship safety (i.e., ventilation, firefighting and flood control) in the ship and will stand all shipboard watches, making all security patrols of the ship, the moorings, and the immediate adjacent pier. (2) Industrial Activity. Th e industrial activity continues to perform all contract requirements until delivery. The industrial activity will support Ship’s Force in the performance of those requirements assumed by Ship’s Force as required. (3) Supervising Authority. During prep arations for In-Service, conduct liaison between Ship’s Force and the industrial activity to ensure the above division of responsibility is understood and agreed to. Verify that a schedule of compartment or space and system turnover is prepared, mutually agreed to, and that a means to identify deficiencies in systems and spaces turned over to Ship’s Force is executed.

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-9 3.3.13 Degaussing or Deperming. Reference (x) establishes the provision for checking, operating and maintaining degaussing systems. Reference (y) contains basic principles and background information concerning degaussing. a. Deperming, a method of ne utralizing the magnetic field of a ship’s hull to minimize permanent magnetism, is required for all new construction ships. b. A listing of degaussing or deperming facili ties currently available is contained in the Degaussing Folder (NAVSEA Form 8950/1) which is issued to individual ships. c. Degaussing or deperming requirement s must be accomplished per Volume VI, Chapter 12 of this manual. 3.3.14 Light-Off Assessment (Surface Force Ships only). a. Light-Off Assessments (LOA) for boilers , Main Propulsion diesel and gas turbine ships will be conducted before propulsion plant operations at an appropriate time before completion of the fitting out availability. The ISIC, with the assistance of Afloat Training Group Atlantic or Pacific, will determine if ship’s training procedures and status support safe plant operations, if management programs are effective, if the propulsion plant is ready for light-off and Ship’s Force ability to combat a main space fire. b. References (z) and (aa) address propulsi on plant LOAs administered by the ISIC, with the assistance of Afloat Training Group Atlantic or Pacific, and recommend that Ship’s Force is to have a minimum of two weeks after completion of industrial activity work in the engineering spaces prior to the LOA. Experience has shown this two- week period is crucial, not only to successful completion of the LOA but to the operation of the ship subsequent to construction. If it appears the two-week interval is in jeopardy, the ship’s OIC should discuss ways to speed up the industrial activity work with the Ship Superintendent or this subject should be addressed at Supervising Authority progress conferences. c. Completion of industrial activity work should be interpreted as meaning that all known work and testing authorized for accomplishment by other than Ship’s Force, and which is necessary to support LOA, is complete, including the removal of associated staging and equipment, reinstallation of access doors and hatches, cleanup and painting. Fuel and lube oil, and feedwater should be on board. Partial or temporary installations do not meet completion criteria except as necessary to support the LOA itself or, in the case of lagging pads, as necessary to allow readjustment upon light-off to hot settings of regulators, reducers, and relief valves. The systems and spaces involved in LOA vary from ship to ship, but normally include all systems and spaces needed to support the plant(s) being inspected. This would include main and auxiliary machinery spaces, switchboards, diesels, shaft alleys, uptakes, repair lockers, oil laboratories and calibration laboratories for Automatic Boiler Control systems, etc. Confirm spaces subject to inspection with the Afloat Training Group. d. Emergent work items or additional disc repancies requiring industrial activity work that become apparent during the pre-LOA period need to be accommodated. Normally these requirements can be worked during night shifts or inclusive weekends.

p. 138

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-10 However, any industrial activity work during this period will be permitted only with the consent of the Supervising Authority and the OIC. e. This Key Event is largely an exercise in attention to detail and coordination at and between all three levels of maintenance activity (Ship’s Force, the Shipbuilder and the Supervising Authority). LOA preparations should begin months before the availability. f. First-hand inspections of main and aux iliary machinery spaces are most effective when industrial activity personnel are not on board (weekends and holidays). During these periods, joint inspections by the Engineer Officer with Leading Petty Officers are recommended for every main space. Similar inspections of the auxiliary spaces should be conducted by either the CO or the Executive Officer, along with the Leading Petty Officers of those spaces. Discrepancy lists convert readily to work lists. Night repair teams (primarily composed of duty section personnel) can work discrepancies when industrial activity workers are not in the way. g. The Plan of Action and Milestones for a succ essful LOA must be written in detail, at the minor equipment or minor task level, and the more detailed, the better. It is a dynamic document and requires updating and revision daily as the LOA date approaches. 3.3.15 Shipboard Crane Certification Program (Surface Force Ships and Aircraft Carriers as appropriate). The Shipboard Crane Certification Program established by reference (ab) is intended to improve the reliability and safety of all shipboard cranes and is applicable to all cranes mounted on board and cranes assigned to forces afloat (exceptions are listed in reference (ab)). Initial crane certification should be accomplished per reference (ab). 3.3.16 Marine Gas Turbine Inspection. a. Purpose. To validate and certify engine alignment, foundation integrity, engine frame integrity, engine resilient mounts, fluid system cleanliness, intake and uptake cleanliness, compressor and turbine blade integrity, fluids leakage, controls and instrumentation functionality and engine starting and performance. b. Conduct. Marine Gas Turbine inspections must be conducted per Volume IV, Chapter 23 of this manual. 3.4 MAINTENANCE AND MATERIAL MANAGEMENT PROGRAM. 3.4.1 Planned Maintenance System. a. The installation of the Planned Maintena nce System (PMS) on new construction ships should be scheduled to provide maintenance documentation to support the Operational Control Transfer (OCT) of systems and equipment from the shipbuilder to Ship’s Force. This early load out of PMS allows Ship’s Force personnel to become familiar with the maintenance procedures and facilitates the identification of problems with the Maintenance Requirement Cards (MRC) prior to the ship being placed in operation. Local RMC coordinates the scheduling of PMS installations with the ship’s Maintenance and Material Management (3-M) Coordinator. In addition, Naval Sea Logistics Center (NAVSEALOGCEN) is responsible for:

p. 139

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-11 (1) Generating a preliminary List of Effective Pages (LOEP) for Phase I validation. (2) Conducting Phase I of the PMS installation. (3) Generating a final LOEP based on Phase I and 3-M Coordinator Feedback. (4) Notifying local RMC of the required PMS documentation (LOEP requirements) and the date the documentation is required to support Phase II PMS installation. (5) Compile Phase II PMS package and forward to ship. (6) Conduct Phase II PMS installation. (7) Effect additional LOEP corre ctions as a result of Phase II. (8) Outbrief with ship’s PCO or OIC concerning status of ship’s 3-M program. b. PMS installation for nuclear powered sh ips will be conducted approximately six months prior to initial reactor plant criticality. The installation for Surface Force Ships will be conducted at least three months prior to delivery. Installation of PMS is accomplished in two phases. (1) Phase I. Phase I results in the establishment of a ship’s LOEP. Local RMC, utilizing either the LOEP from the previous ship of the class or configuration information provided by Submarine Maintenance Engineering, Planning and Procurement (SUBMEPP) Activity (Submarines only), Supervisor of Shipbuilding Newport News PMS 312C, (Aircraft Carriers) or applicable TYCOM (Surface Force Ships), generates a preliminary LOEP for Ship’s Force review. This preliminary LOEP and copies of the listed Maintenance Index Pages (MIP) are delivered to the new construction unit for a review by the ship’s 3-M Coordinator, Work Center Supervisors and maintenance personnel. Ship’s Force personnel review the documentation, verify MIP to Work Center assignments and approve the preliminary LOEP. Phase I occurs approximately two months prior to Phase II. (2) Phase II. Phase II is the actua l load out of PMS documentation, final verification of the LOEP, generation of preliminary schedules for local RMC review and a Ship’s Force validation of provided documentation. Depending upon the ship class, quantity of documentation, and Ship’s Force preparation, Phase II can last from two to four days. Additionally, maintenance support organizations such as Naval Surface Warfare Center, Philadelphia Division, SUBMEPP or Submarine Monitoring, Maintenance and Support Program Office may be participants. c. The preparation of preliminary Cycle, Qu arterly, or Weekly schedules to support PMS load out prior to the preparation of First Quarter after Overhaul schedules is recommended. As a minimum, the development of a cycle schedule for each work center should be accomplished prior to Phase II PMS installation. As systems or equipment is turned over, Ship’s Force maintenance should be scheduled to support. This preliminary quarterly schedule (schedule “A”) is utilized to track maintenance

p. 140

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-12 prior to the official First Quarter after Overhaul start date. Additional preliminary quarterly schedules identified as “B”, “C”, etc. may be developed as required. d. The “official” PMS start date depends upon several factors: OCT of equipment, available manpower, availability of supporting documentation and the availability of tools, parts, test equipment, and material. The start date is also an arbitrary date arrived at by the ship’s 3-M Manager and 3-M Coordinator. A start date should be selected that causes as little disruption and preparation of schedules as possible. Utilization of preliminary schedules as discussed in paragraph 3.4.1.c of this chapter will allow for the flexibility to start PMS “officially” at the beginning of a quarter. However, should this approach not support your situation, the starting of PMS should be indicated on your quarterly schedule with a yellow vertical line, top to bottom, indicating your start date. e. Inactive Equipment Maintenance (IEM). (1) IEM, per the direction of reference (ac), may be implemented anytime that an equipment will be out of service for thirty days or longer. The implementation of IEM may be appropriate for those systems or equipment which was transferred to ship’s custody early in the construction cycle. Ship’s Force should follow the guidance of reference (ac) when implementing. (2) In deciding whether to place equipm ent in layup, consideration should be given to the training opportunity lost. As long as equipment is in an active status, Ship’s Force will be performing PMS. By virtue of accomplishing those maintenance tasks, they will become more familiar with the equipment, its operation and the maintenance procedures. Maintaining equipment in an active status also allows for the identification of procedural problems within the MRCs. 3.4.2 Technical Feedback Reports. Ship’s Force should start using Technical Feedback Reports (TFBR) to report problems with PMS as soon as the PMS package is installed. TFBRs should be submitted per the requirements of reference (ac). The TFBR tracking log should be established, even if PMS has not officially started. TFBRs are processed through the ISIC for further processing to RMC. If an ISIC is not available, TFBRs are to be processed through the TYCOM or directly to RMC. New construction ships will provide their TFBRs to the local RMC. The current contact information for the RMCs is listed in volume VI, chapter 2, appendix A of this manual. 3.4.3 Establishment of Current Ship’s Maintenance Project. The ship’s Current Ship’s Maintenance Project (CSMP) will be initialized at delivery. That does not mean however, that significant maintenance related events do not happen during the construction period. In fact, every industrial activity has their own deficiency tracking programs, all of which contain a certain degree of data that should be retained in the ship’s CSMP. The problem is that this data resides on industrial activity computers which for the most part do not “talk” to Navy computers. When the ship leaves the industrial activity, it generally leaves without this data. Ship’s Force will load into the CSMP any deficiencies not adjudicated at delivery and any historical construction related maintenance data deemed worthy of future retrieval.

p. 141

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-13 3.4.4 Naval Tactical Command Support System. Space & Naval Warfare Systems Center Atlantic (SSC Atlantic) and Space & Naval Warfare Systems Center Pacific (SSC Pacific) are responsible for the software installation, installation training, hardware support and software support. Ship’s Force should initiate liaison with the appropriate SSC Atlantic and Pacific team to facilitate installation or installation training. All support requests are initiated via the Navy 311 Help Desk. Additional details describing the SSC Atlantic and Pacific support functions are addressed in Chapter 2, paragraph 2.10.5 of this volume. 3.5 EQUIPMENT LOAD OUT. 3.5.1 Test Equipment. The General Purpose Electronic Test Equipment (GPETE) load out involves personnel from the ship, the Supervising Authority, NAVAIRWARCEN, China Lake, CA. The actual load out will vary dependent upon the platform. Generally, the equipment arrives during the construction phase and is stored by the shipbuilder until load out. Ship’s Force, if not requested to do so by the Supervising Authority, should inventory and identify shortages while the GPETE is in storage. Coordinate with TYCOM METCAL Point of Contact to assist in resolving TMDE deficiencies. 3.5.2 Hand Tools and Weight Handling Equipment. Hand tools and weight handling equipment will also be arriving. Inventory of this equipment against Allowance Equipage Lists (AEL) or Allowance Parts Lists (APL) or class specific load lists at the earliest opportunity ensures the required support material is available when maintenance of equipment begins. Weight handling equipment requires certification prior to use and while it may be months before this equipment is required, a recall schedule should be developed to get the equipment certified. 3.6 LOGISTIC SUPPORT. 3.6.1 Technical Manuals and Drawings. Technical manuals and drawings are provided by the Supervising Authority and the Navy. The shipbuilder develops and provides manuals and drawings for all Contractor Furnished Equipment (CFE), including equipment furnished by subcontractors. In the case of Government Furnished Equipment (GFE), the shipbuilder will identify the required manuals to the Navy Publication and Printing Service Manuals Office, Washington, D.C., via the Supervising Authority and the Navy Shipbuilding Program Manager. Navy Publication and Printing Service Manuals Office will deliver the manuals to the shipbuilder. For the first ship of a class, equipment manuals for new design GFE may not be immediately available from the Navy Publication and Printing Service Manuals Office. These manuals will be shipped with the equipment by the vendor. The shipbuilder will provide stowage and custody of this documentation until actual shipboard load out. To ensure all required technical manuals and drawings are received, initial documentation validation should be accomplished on a random sampling basis with emphasis placed on low visibility items such as power supplies and electronic subsystem manuals. Final validation will occur during load out. Each Navy Shipbuilding Program Manager has assigned an activity with the responsibility for loading out of Technical Manuals and Drawings. Contact the Supervising Authority or the Navy Distance Support Anchor Desk to determine the Navy Shipbuilding Program Manager. The Anchor Desk can be reached at 1-877-418-6824 or by e-mail ([email protected]). a. Ship Systems Manual (SSM) or Ship Info rmation Book (SIB). The SSM or SIB (SSM for submarines and SIB for surface force ships and aircraft carriers) are the primary descriptive and operating manuals for non-propulsion plant ship systems. They are

p. 142

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-14 designed as a class manual and are the basic source of information for locating, describing and operating the following non-propulsion plant systems: (1) Mechanical. (2) Piping. (3) Electrical. (4) Electronic. (These manuals do not provide detailed maintenance information but do reference sources of information on maintaining, testing, troubleshooting, installing and removing these systems and equipment. SSMs and SIBs must be turned over to the ship prior to or at OCT or custody transfer of the system or equipment.) b. Engineering Drawings. All engineering dr awings belong to one of two groups: ship construction drawings or equipment drawings. Each group is made up of several types of drawings. (1) Ship Construction Drawings. These drawings are developed for building the ship and to reflect installed systems. These drawings are each assigned a seven-digit NAVSEA number and depending upon the platform a three-digit Component Identification Number, Ship Work Breakdown Structure or Expanded Ship Work Breakdown Structure may appear on the drawing. The NAVSEA number identities the drawing and the Component Identification Number, Ship Work Breakdown Structure or Expanded Ship Work Breakdown Structure assigns the drawing to a group of related drawings. Ship construction drawings are usually “class drawings” however, ships of a class, built at different times, may vary from the original design as improvements are made. This necessitates the development of hull unique construction drawings which have been verified by the shipbuilder and Supervising Authority to reflect an individual ship’s configuration. Systems requiring these Selected Record Drawings (SRD) are identified in the ship’s building specifications. (2) Equipment Drawings. Equipment draw ings describe equipment shown on ship construction drawings. They are prepared by industrial activities or equipment manufacturers and may be called vendor drawings. Equipment drawings are rarely assigned NAVSEA or any other government controlled number. These drawings are identified by a Commercial and Government Entity code with a manufacturer’s drawing number. c. Drawing Types. Engineering practices have developed common titles that are used on most drawings. By understanding the kind of technical information associated with each title, the drawing needed for a given job can be determined. The following is a list of common drawing types (they may be either equipment or ship construction drawing group types). (1) System diagrams - A system diagram shows how a system is designed and describes the relationship among system components. System diagrams do not include physical or dimensional data, but normally refer to other drawings and documents that contain detailed information.

p. 143

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-15 (2) Arrangement drawings - Arrangement drawings show locations, dimensions, and other system component information necessary to make correct installation on the ship. (3) Assembly and subassembly drawings - Assembly and subassembly drawings show how individual parts fit together to form a larger component or equipment. (4) Installation drawings - Installa tion drawings show piping, foundations, ventilation ducting, and other installation details. Installation drawings are used to install systems and equipment in the ship. (5) Outline drawings - Outline drawings show the outward appearance of major system components and contain dimensions and service requirements necessary to install the component. (6) Detail drawings - Detail drawings show dimensions and other manufacturing data for individual parts of components. (7) Electrical drawings - Electrical drawings have a family of titles similar to those of other engineering drawings. Proceeding from the general to the detailed the following are the common electrical drawing types: (a) Electrical system wiring diagrams - Electrical system wiring diagrams show how the overall system is intended to function. (b) Cabling drawings - Cabling drawin gs describe cable runs in greater detail (similar to piping system diagrams). (c) Wireway drawings - Wireway draw ings show how cables are routed from one point to another in the ship (similar to system arrangement drawings). (d) Schematic wiring diagrams - Schematic wiring diagrams describe individual wires inside the cables and how they connect to components. (e) Wiring tables - Wiring tables prov ide detailed point-to-point data for connecting ship’s wiring between components. d. Technical Variance Documentation (T VD). Drawings may be amended with supplementary information called TVD. A set of TVD is a collection of documents describing how the as-built configuration of a ship differs from the class drawing design. TVD is not intended to be a revision to a drawing. Liaison Problem and Solution Sheets, Engineering Notices, Waivers and Deviations are some of the documents that make up TVD. e. Format of Onboard Drawings. Very fe w drawings are provided to ships and shore facilities in hard copy form. Most are on microfilm aperture cards or microfiche, collectively known as microform. For selected platforms, Compact Disc Read Only Memory (CD-ROM) is being utilized. However, some of the more important SRDs are provided in hard copy as well as in other mediums. f. Ship Drawing Index (SDI). The SDI lists all drawings for a class of ship. Using the SDI is the only way to determine a drawing’s applicability. In addition to drawing

p. 144

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-16 applicability, it provides drawing revision applicability and TVD applicability. The SDI will also identify whether a drawing contains Submarine Safety (SUBSAFE) information, Noise Control information or is an SRD. 3.6.2 Unrestricted Operations Maintenance Requirement Cards (Submarines only). a. Reference (ad) establishes the maintenance requirements and identifies the responsibilities and actions required to support continued unrestricted submarine operations to design test depth. This program is invoked on all SUBSAFE certified submarines. To support this program, the Navy Shipbuilding Program Manager issues individual manuals containing required, periodic SUBSAFE maintenance actions for each class and in some instances particular ships. b. Load out of Unrestricted Operations (U RO) MRCs will be accomplished at delivery. The ISIC SUBMEPP Representative will provide to the ship’s Quality Assurance Officer the ship’s copy of the “URO CD-ROM”. SUBMEPP manages the URO program for Navy Shipbuilding Program Managers. c. Upon receipt of the naval certification message of new ship delivery to the fleet, SUBMEPP will update the URO Last Maintenance Accomplishment (LMA) dates to reflect the first day of the month following ship's delivery. d. Upon receipt of the nava l certification message of new SSN completing Post Shakedown Availability (PSA), SUBMEPP will update the UROs LMA dates to reflect the first day of the month following PSA End Date. URO tracking by SUBMEPP and the ISIC will commence at the completion of delivery. e. Additional information concerning the URO program can be found in Volume VI, Chapter 25 of this manual. 3.6.3 Preventive Maintenance Requirement (Submarines only). a. The integration of the Class Maintenan ce Plan forms the basis of the Preventive Maintenance Requirement (PMR) program. The PMR program is developed and managed for Navy Shipbuilding Program Managers by SUBMEPP Activity. b. Load out of PMR Inventories and Sche dules will be made available from the Maintenance & Ship Work Planning program at delivery. These are provided by the shipbuilder via the URO/PMR MRCs on the ship’s Advanced Technical Information System (ATIS) drive. c. Upon receipt of the naval certification message of new ship delivery to the fleet, SUBMEPP will update the PMR LMA dates to reflect the first day of the month following ship's delivery. d. Upon receipt of the naval certification message of new construction submarines completing PSA, SUBMEPP will update the non-flask recertification PMRs LMA dates to reflect the first day of the month following PSA End Date. PMR tracking by SUBMEPP and the ISIC will commence at the completion of PSA delivery. e. Additional information concerning the PMR program can be found in Volume VI, Chapter 24 of this manual.

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-17 3.7 OPERATIONAL CONTROL TRANSFER. OCT, depending on the platform, will happen in one of several ways. The entire ship is turned over at one specific time (ship custody transfer), compartments or spaces are turned over as completed, or systems are turned over as completed without regard to space completion. a. The shipbuilder will: (1) Ensure all testing is complete to the most practical extent possible. (2) Provide Ship’s Force and the Superv ising Authority with a turnover schedule. (3) Conduct a review of all existing work and deficiencies with Ship’s Force and the Supervising Authority and determine those items that must be cleared or resolved to support a safe and operational system turnover. (4) Verify system, space or ship ready for turnover. (5) Conduct walk-through with Ship’s Force. (6) Execute turnover. b. Ship’s Force should be prepared to: (1) Provide system experts for walk-throughs. (2) Address concerns regarding turnover to the Supervising Authority’s Ship Manager. (3) Ensure all work and deficiencies are cleared or resolved to ship’s satisfaction prior to acceptance. (4) Assume maintenance responsibility u pon receipt. (PMS installation should be scheduled to support OCT). NOTE: IN SOME INSTANCES, SYSTEMS MAY BE TURNED OVER THAT REQUIRE TEMPORARY SUPPORT SYSTEMS. THE INDUSTRIAL ACTIVITY WILL PROVIDE OPERATING INSTRUCTIONS, DRAWINGS (AS NECESSARY) AND OPERATING INDOCTRINATION TO SHIP’S FORCE. FOLLOWING THE REMOVAL OF TEMPORARY SUPPORT SYSTEMS, SHIP’S FORCE AND THE SHIPBUILDER SHOULD BE PREPARED TO CONDUCT ADDITIONAL WALK-THROUGHS. 3.8 SOUND SILENCING PROGRAMS UNIQUE TO NEW CONSTRUCTION (MHC and SSN only). a. Isolation System Survey. During the construction process, the shipbuilder, through Noise Reduction Program requirements, periodically inspects the ship to identify incorrect installation and poor construction techniques relating to the silencing nature of the ship. It is imperative that no sound shorts exist between sound isolated systems or components and the hull structure. Ship’s Force can play a major role in the inspection process by identifying deficiencies. This survey is the basis for acoustic measurements to be completed in subsequent surveys. Additional information concerning submarine noise reduction surveys is addressed in Volume VI, Chapter 23 of this manual.

p. 146

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3-18 b. (Submarines only) Topside and Housekeeping Survey. During the construction process, this survey is completed to accomplish two aspects of silencing. First, the topside inspection checks the outside of the pressure hull, especially flow exposed areas, to ensure that tones or rattles are not caused by loose gear, fairing plates, and other discontinuities. Secondly, the housekeeping inspection checks the inside of the pressure hull to ensure sound shorts do not occur as a result of installation of lockers and locker doors, stowage, clogged ventilation ducts or filters, etc. This survey usually identifies problems associated with items not covered by ship design, but those items typically handled by the ship. c. Structure borne and Overside Survey s. Upon installation of Noise Critical components and their associated operating systems, structure borne noise surveys are accomplished to check the acoustic nature of the installation. Proper installation of isolation features and proper maintenance of the component during any layup is crucial to the success of this survey. Ship’s Force must continually be aware of the installation practices of the shipbuilder and thoroughly inspect the installation for sound shorts and proper alignment prior to system or component turnover. The Overside Survey is accomplished outside the hull (pressure hull for submarines) as an indication of radiated noise. Proper operation of systems and components during this process is crucial to satisfactory acoustic levels. Reference (ae) provides additional information concerning acoustic surveys for submarines.

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3D-1 APPENDIX D APPENDIX D IN-SERVICE COMPARTMENT SURVEILLANCE GUIDE (AIRCRAFT CARRIERS AND SUBMARINES ONLY) 1. As directed by OPNAVINST 4700.8 , approximately two to four weeks for submarines, or two to four months for aircraft carriers, prior to the first Sea Trial, a nuclear ship is to be placed “In- Service”. A prerequisite to placing the ship “In-Service” is satisfactory habitability conditions. There still remains industrial and fitting out work prior to ship completion and readiness for Sea Trials. The accepting authority must take this action into consideration when scheduling the habitability inspection prior to the crew moving on board. The purpose of this inspection is to ascertain whether the spaces within which the crew will live, primarily berthing and messing, are clean, safe, and ready to receive the crew. 2. Spaces that are considered finished and ha ve been inspected by Ship’s Force should be complete to approved plans. 3. The following is a list of attributes which should be checked for completeness during “In- Service” inspections of spaces in the final phases of construction. a. Cable hanger and banding - properly installed. b. Cleanliness - equipment, equipment space, and bilge area free of industrial dirt and debris (there may be areas of light dust). c. System completeness - handwheels, spray shields, etc. are installed. d. Bilges - free of standing oil. e. Compartment free of damage - pipe scars, arc strikes, etc. f. Grounding straps - properly installed. g. Lockers - stowage and shelving solidly attached and operable. h. Compartment lighting - installed and operable. i. Compartments - to be free from constr uction material and any unsecured objects that may cause a threat to personnel safety. j. Safety chains, ladders, and handrails - installed, fastened in place, and per plan. k. Permanent deck plates - corners bolted down, well fitted, and do not present a tripping hazard (deck plates over bilge areas need not be bolted at this time). l. Welding - all structures complete. m. Preservation paint - neat and comple te, with approved color schemes. Basic preservation applied to all structures and equipment (areas of minor rust and bare ferrous metal are acceptable at this time in compartments in the final phases of construction). n. Appearance paint (applied for cosmetics rather than preservation) - applied to routinely visible surfaces and presents a neat appearance.

p. 170

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3D-2 APPENDIX D o. Accessibility of equipm ent - convenient for operation, repairs, replacement, maintenance, testing, and visible use. p. Store Rooms - complete (i nstallations and painting). q. Marking of equipment - valve labels, na me plates, instruction and warning plates installed and readable. r. Protection of equipment from any da mage - as required by plans or planned maintenance guidance (e.g., Scott Foam). s. Berthing and Messing arrangement - prope r type, accessibility, clearance, seating capacity, etc. per plan. t. Joiner work - compartment bulkheads, overhead structures, moldings, and furniture installation complete and presents a neat appearance; Formica will be free of damage. u. Condition of deck coverings (Tile and Terrazzo) - free of any damage and major discoloration. v. Watertight and non-watertight doors - inst allation complete, well fitted, with proper operation (ease of opening and closing) and protection devices installed.

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 I-3E-1 APPENDIX E APPENDIX E SAMPLE PRE-COMMISSIONING HABITABILITY INSPECTION CHECKLIST FOR NEW CONSTRUCTION SHIPS Ref: (a) OPNAVINST 4700.8 - Trials, Accep tance, Commissioning, Fitting Out, Shakedown and Post Shakedown Availability of U.S. Naval Ships Undergoing Construction or Conversion 1. A pre-commissioning habitability inspecti on is required for new construction ships by reference (a). The purpose of the inspection is to verify that living and messing spaces are clean, safe and ready to receive the crew. Upon completion of the inspection, the inspection team leader will provide copies of the deficiency list to the Navy Shipbuilding Program Manager’s representative, the Supervising Authority, the Commanding Officer of the ship’s pre- commissioning unit and the TYCOM. 2. This assessment is not of the magnitude or de tail required by the Supervising Authority to ensure shipbuilder compliance with all building specifications in the contract or by the Board of Inspection and Survey during acceptance trials. This assessment is a qualitative judgment of the ability of the crew to live on board safely and comfortably during the fitting out period. This assessment does not fulfill shipboard system certification requirements or other inspection requirements related to food service sanitation, laundry and dry cleaning, potable water and marine sanitation devices. 3. Areas to be inspected include general safety and sanitation, galley, scullery, messing, dry food storage spaces, refrigerated food storage spaces, berthing spaces, washrooms, showers, heads, lounges and potable water. Only spaces designated to support initial crew move aboard will be inspected. For example, if only the aft galley will be used at move aboard, the forward galley will not be inspected. 4. It is understood that not all equipment, spaces and systems aboard the ship will be completed and transferred to Ship’s Force at the time of the assessment. If a space or system to be inspected has not been transferred to the crew, the shipbuilder and Supervising Authority will present the space or system to the inspector. If a space or system has been accepted by the crew, the crew will present the space; cognizant shipbuilder and Supervising Authority personnel should be present. As remaining habitability related spaces or systems are completed after crew move aboard, the Supervising Authority and Ship’s Force are responsible for inspecting spaces or systems per the turnover procedure specified in the contract. 5. The pre-commissioning habitability inspection t eam will evaluate the following areas utilizing the enclosed inspection checklists: A. General B. Food Service C. Living Spaces D. Freshwater E. Collection, Holding and Transfer (CHT) System (See Note) F. Laundry and Dry Cleaning (See Note) NOTE: OPERATIONAL LAUNDRY FACI LITIES AND WASTE REMOVAL SYSTEMS ARE CONSIDERED DESIRABLE TO SUPPORT CREW MOVE

CHAPTER 4

p. 184

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-2 4.1 PURPOSE. To identify the Trials incident to new construction, provide a brief description of each, identify unique support requirements and list specific test areas. 4.2 DOCK TRIALS. 4.2.1 Purpose. To demonstrate that major systems and equipment is ready to support Fast Cruise and Sea Trials. 4.2.2 Conduct. Dock Trials are conducted by Ship’s Force per reference (a) for nuclear powered ships and following the Builder’s Contract for Surface Force Ships. Normally a period of one day is assigned for integrated Dock Trials, tests and evolutions. 4.2.3 Scheduling. Dock Trials must take place prior to crew certification for submarines, prior to Fast Cruise for aircraft carriers and prior to the first Ship’s Force underway period for Surface Force Ships. Dock Trials should be scheduled by mutual agreement between the ship, shipbuilder and the Supervising Authority. Dock Trials should be completed with adequate time allowed to correct deficiencies. NOTE: THE SHIPBUILDER OR SUPERVISING AUTHORITY MAY DESIRE TO CONDUCT “MACHINERY CHECKOUT” OR SYSTEM CHECKS PRIOR TO DOCK TRIALS IN ORDER TO TEST SHIP SYSTEMS. COMPLETION OF REPAIRS AND MODIFICATIONS ARE NOT REQUIRED EXCEPT FOR SYSTEMS THAT DIRECTLY SUPPORT THE TESTS. IN ORDER TO SUPPORT THESE EVOLUTIONS, CLOSE LIAISON BETWEEN THE PROSPECTIVE COMMANDING OFFICER (PCO) OR OFFICER IN CHARGE (OIC) AND THE SHIPBUILDER OR SUPERVISING AUTHORITY WILL BE REQUIRED. NOTE: SHIP’S FORCE MUST HAVE OPERATIONAL CONTROL OF ALL SHIP’S SYSTEMS REQUIRED FOR SEA TRIALS PRIOR TO THE CONDUCT OF DOCK TRIALS. 4.2.4 Specific Test Areas. There are specific tests which relate to both system and ship safety which must be conducted in preparation for Fast Cruise and Sea Trials. Appendix A of this chapter lists the minimum alongside tests to be conducted by Ship’s Force during Dock Trials. References (b) and (c) provide additional information for aircraft carriers. 4.3 FAST CRUISE. 4.3.1 Purpose. To train the crew and determine the crew’s ability to safely take the ship to sea. 4.3.2 Conduct. a. Fast Cruise is conducted per references (a), (d), and (e). b. In addition to the normal underway routine, the Commanding Officer (CO) or OIC must have all equipment operated to check for proper operation and to determine the state of training of the crew. Fast Cruise must, as far as is practical, simulate at-sea operating conditions. It is to be conducted by Ship’s Force and is to be unhampered by construction or repair work or by movement of industrial activity personnel through the ship. Neither the shipbuilder nor the Supervising Authority will schedule any trials, tests or other work on the ship during this period.

p. 185

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-3 c. The ship will be operated as if underway, simulating the various evolutions required for safe operation. Each underway watch section must be exercised in the evolutions which are normally performed on a section basis. Check out all communication systems during each evolution. Ensure that each is in proper working order and that, where duplicate systems exist, a priority system is designated. d. (Submarines only) The Fast Cruise should be a minimum of four days in duration. It should be completed within a five-day period. It should end not more than three days prior to underway trials. Normally, the ship will go to sea for underway trials within a day after completion of Fast Cruise. Should the 72-hour period be exceeded, the Type Commander (TYCOM) may direct an additional Fast Cruise. 4.3.3 Scheduling. Fast Cruise is scheduled immediately prior to underway trials. Approximately 7 days prior to the first underway trial, the Supervising Authority with the concurrence of the CO or OIC notifies the Navy Shipbuilding Program Manager that the ship is ready to commence Fast Cruise (Volume I, Chapter 2, paragraph 2.4.1.v of this manual refers). 4.3.4 Specific Test Areas. Appendix B of this chapter lists the minimum evolutions and drills to be conducted during Fast Cruise. Additional drills and evolutions are at the discretion of the PCO or OIC. References (b) and (c) provide additional information for aircraft carriers, reference (e) for Surface Force Ships. 4.3.5 Reports (Nuclear Powered Ships only). The Supervising Authority with concurrence from the PCO or OIC reports the successful completion of Fast Cruise using the format of Volume I, Chapter 2, Appendix B 7 of this manual (submarines only). Volume I, Chapter 2, paragraph 2.4.1 of this manual refers. 4.4 SEA TRIALS. 4.4.1 General. a. The policies, procedures and responsibilities pertaining to Sea Trials for ships undergoing construction are set forth with reference (d). References (a), (f), (g) and (h) augment the basic instruction. b. Sea Trials for the various platforms undergoing construction differ in complexity, conduct and scope of Ship’s Force involvement. Surface Force Ship platforms such as the DDGs or LHDs go through Builder’s Trials (BT) which for the most part are conducted with little to no involvement by Ship’s Force. Industrial activity employees take the ship to sea and perform the majority of system or equipment testing. Paragraph 4.4.2 of this chapter provides additional information concerning BTs. c. Nuclear powered ships’ Sea Trials, however, are much more orientated to Ship’s Force involvement. Ship’s Force is responsible for taking the ship to sea and operating all shipboard equipment. The terms Alpha Trial, Bravo Trial, Charlie Trial, Combined Trial (CT) and Guarantee Material Inspection (GMI) are most often associated with submarine Sea Trials whereas aircraft carriers undergo BTs prior to Acceptance Trials (AT). Subsequent paragraphs provide amplifying information concerning these trials. d. Underway trials following construction, particularly initial submerged and test depth trials for submarines, must be undertaken with the knowledge that the crew lacks

p. 186

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-4 recent experience operating as a unit and that the ship’s structure and fittings have not been tested in an at-sea environment. All tests and procedures must be conducted carefully and methodically. In the case of submarines, systems and components designed to operate at test depth should not be exercised at test depth for the sole purpose of proving the design. They should be operated at the deepest depth at which they might be used. Trials and tests which are inherently hazardous should not be conducted. For example, a submarine’s hovering system should not be demonstrated at test depth. Reference (i) provides additional information concerning the testing of submarine seawater systems during underway Sea Trials. Sea Trials following new construction are normally conducted with a significant number of “riders”. These riders represent Naval Sea Systems Command (NAVSEA), TYCOM, Shipbuilder and Board of Inspection and Survey (INSURV) personnel onboard to observe various tests and trial evolutions. The ship’s normal load out of Lithium Hydroxide canisters, Lithium Hydroxide curtains, Emergency Air Breathing (EAB) masks, Submarine Escape and Surface Survival Personnel Equipment (SESSPE) suits and Oxygen candles is not sufficient to support this increase in personnel. Therefore, an additional four Lithium Hydroxide canisters, four Lithium Hydroxide curtains, one EAB mask, one SESSPE suit (as applicable), and two oxygen candles must be carried for each rider exceeding normal crew manning. Lithium Hydroxide canisters, EABs, SESSPE suit (as applicable) and Lithium Hydroxide curtains are to be obtained from the industrial activity. e. The following general conditions apply: (1) A shipbuilder generated, Supervising Authority, Navy Shipbuilding Program Manager or TYCOM approved agenda is required for each Sea Trial. (2) All trial periods must be organized such that each member of the crew has an opportunity to get six uninterrupted hours of sleep during each 24-hour period. Sea Trial elements which can be accomplished by a normal watch section may be conducted concurrently with crew rest periods. (3) Sea Trials should normally be scheduled to allow at least three weeks between CT or AT and the scheduled delivery date. (4) The prerequisites for aircraft carrier and submarine Sea Trials are a Pre-Critical Reactor Safeguard Examination (RSE), Crew Certification, Dock Trials and Fast Cruise. (5) Each submarine watch section must be provided with approximately two hours’ experience submerged at moderate speeds prior to the deep dive or full power run. (6) Critical operation of reactors while naval nuclear powered ships are in a Naval or private industrial activity will be governed by reference (j). Prior to delivery, permission to conduct critical reactor plant operations must be obtained by the Supervising Authority from NAVSEA Nuclear Propulsion Directorate (08). (7) During inspections, deficiencies should be limited to those items for which a correction is mandatory to ensure safe operation during Sea Trials.

p. 187

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-5 (8) At the start of Fast Cruise the ship should be ready in all respects for the commencement of Sea Trials with the exception of the additional training the crew will receive during Fast Cruise. (9) Inspectors must determine that all work and testing necessary to support Sea Trials has been completed or identified for completion prior to commencement of Fast Cruise including the following: (a) All ship systems which affect safe operation during Sea Trials must be operable. (b) All work necessary for safe operation of the ship during Sea Trials has been satisfactorily completed and tested. Included must be a check for any special configuration or installations ensuring that they have been authorized by the proper authority (NAVSEA and TYCOM), that their impact has been fully assessed and that the Sea Trial agenda addresses these impacts or limitations. (10) NAVSEA and the Supervising Authority are expected to properly discharge their responsibilities for quality assurance and control of authorized industrial work (e.g., it is not necessary for the Immediate Superior in Command (ISIC) inspections to inspect the quality of the pressure hull radiographs or other nondestructive test records of the industrial activity). (11) Following completion of the required training and material readiness certification, the CO or OIC must keep the ISIC fully informed of any changes in personnel, training or material status which could affect the validity of certification. Prompt notification is required to permit revision of Operational Orders and services required. (12) (Submarines only) Prior to getting underway for Sea Trials, Shipyard, Ship’s Force and Type Commander must jointly agree that the required seven day supply of Oxygen (O2) and seven day supply of Carbon Dioxide (CO2) removal capacity will be available in each compartment, based upon the number of expected occupants of that compartment, independent of the supply and removal capacity in the other compartment(s). (13) Sea Trial Situation Reports (SITREP) (Submarines only). Ships executing Sea Trials associated with a new construction program must submit daily SITREPs using the message format in Volume II, Part I, Chapter 3, Appendix BM of this manual following the SITREP guidelines contained in Volume II, Part I, Chapter 3, paragraph 3.6.8.3.9 of this manual. 4.4.2 Builder’s Trials. BTs conducted by a private shipbuilder are normally comprised of a Builder’s Dock Trial (BDT) and one or more Builder’s Sea Trials (BST). Some DDGs are currently undergoing three BSTs. The first BST, referred to as an Alpha Trial by the DDG community, is primarily a propulsion plant trial. The second BST, referred to as a Bravo Trial, primarily covers Combat System evolutions and the third BST is the AT. While the actual content of BSTs will be dependent upon the platform, the primary purpose is still the same; the validation of ship’s equipment and systems in preparation for Charlie Trials or AT. Appendix C of this chapter provides a sample listing of tests to be performed during an aircraft carrier’s BT.

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-6 4.4.3 Alpha Sea Trial (Submarines only). A submarine’s first underway period primarily conducted for propulsion plant testing and the initial tightness dive. (First ship of each class normally conducts a dive to Test Depth during this trial). a. Testing. The tests and evolutions to be carried out while on the surface en-route to the test dive area, just prior to the initial dive and during the initial dive are identified in Appendix D of this chapter. b. Restrictions. The following rules apply to the conduct of trials and tests associated with ship construction, Navy Shipbuilding Program Manager sponsored Trials and Tests or any other situation where the ship is requested to conduct trials or tests: (1) No test or trial event will be conducted that requires crew intervention to avoid exceeding normal operating limits. Trial agendas will be based on the expectation that the ship will remain within normal operating limits of the Submerged Operating Envelope (SOE) and at angles less than 30 degrees. (2) The trial director must be prepared to project whether the next event might exceed normal operating limits based on the empirical results of the previous event. A run that is predicted to exceed normal operating limits should be deleted along with the more demanding runs of that sequence. (3) Any run which will result in exceeding normal limits of the SOE or 30 degree angles but which is essential to provide adequate test data must be specifically approved by the TYCOM. The test or trial sponsor will obtain this permission. (4) A violation of the SOE limit or exceeding a 30-degree angle, not previously approved, must be reported by unit Situation Report (SITREP). No further testing or trials will be conducted until TYCOM concurrence is obtained. (5) Specific written approval by the TYCOM is not required to operate outside the upper limits of the SOE, i.e., shallow and fast, while conducting the following operations during Sea Trials or tests following an agenda approved by the ISIC, Navy Shipbuilding Program Manager or higher authority: (a) Conducting full power runs or cavitation curves. (b) Navy Shipbuilding Program Manager sponsored acoustic trials following an approved acoustic trial agenda. (6) The first underway will be limited in scope. The initial tightness dive will be a deliberate, planned, step-by-step evolution as defined in Appendix D of this chapter, using conservative angles and moderate speed. The maximum water depth for this dive must be 400 feet, as prescribed by Appendix D of this chapter. c. Escort. The submarine must be accompanied by an escort properly equipped with sonar communication equipment. The escort ship must have the capabilities identified in Appendix E of this chapter. Specifically, an escort is required for:

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-7 NOTE: FOR ALPHA SEA TRIAL, A BACK-UP ESCORT WILL BE ASSIGNED AND READY IN CASE OF FAILURE OF THE PRIMARY ESCORT. (a) Initial tightness dive after construction and the first dive to any deeper depth. (b) Initial deep dive after construction. (c) Emergency Main Ballast Tank (EMBT) blow test under the following conditions: 1 Blow for first time from each depth. Trial agenda will specify depths. 2 Any blow from greater than 400 feet. Rationale is to give submarine added protection to prevent interference from any surface contact. NOTE: IN ALL CASES, HULL STRENGTH, TIGHTNESS AND VALVE OPERATIONS WILL HAVE BEEN TESTED TO A DEPTH EQUAL TO OR GREATER THAN EMBT BLOW DEPTH BEFORE TESTING EMBT BLOW SYSTEM. (d) The second and subsequent underway periods if major hull and system work has been accomplished since the last Sea Trial. (2) Alternate Escort. If a surface ship meeting the requirements of Appendix E of this chapter is not available, then a submarine with the required capabilities will be assigned. In any event, each situation must be examined on a case basis and approval by the TYCOM must be obtained to conduct the initial tightness or test depth dives. (3) When an escort ship is other than a submarine, an officer qualified in submarines (Gold Dolphins) must be embarked during the escort duty. (4) Assignment of Submarine Rescue Diving Recompression System (SRDRS). A SRDRS consisting of a designated SRDRS support ship, will be placed in a modified alert status at the beginning of those Sea Trials requiring an escort for: (a) Ship’s initial tightness and deep dive events. (b) Subsequent Sea Trials until the completion of the initial dive to design test depth. (c) If, in the TYCOM’s judgement, a Sea Trial requires an escort due to major hull cuts, etc., the TYCOM must obtain Navy Shipbuilding Program Manager concurrence when determining the need for escort and SRDRS services. The ship conducting Sea Trials will notify Commander, Submarine Development Squadron Five and Commander Naval Sea Systems Command (COMNAVSEASYSCOM) when SRDRS is no longer required due to completion of the events necessitating the alert status or due to delays in completing Sea Trials.

p. 190

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-8 (d) The cognizant shipyard activity and Commander Submarine Force Atlantic or Commander Submarine Force Pacific must notify COMNAVSEASYSCOM and Commander, Submarine Development Squadron Five 30 Days prior to the SRDRS need date. All changes in the requested modified alert date will be immediately identified to COMNAVSEASYSCOM and Commander, Submarine Development Squadron Five. Sample messages in Volume II, Part I, chapter 3, Appendices BN and CQ of this manual. (e) Commander Submarine Force Atlantic or Commander Submarine Force Pacific must identify the SRDRS support ship in the tasking message. The TYCOM must ensure Airport and Seaport verification checks are current or accomplished to support SRDRS activation. (f) The SRDRS is not required to be placed in a modified alert status for those Sea Trials requiring an escort solely for the accomplishment of an EMBT blow from depths greater than 400 feet. d. Reporting Criteria. The Supervising Authority is responsible for reporting the satisfactory completion of Alpha Sea Trial to the Navy Shipbuilding Program Manager. Volume I, Chapter 2, Appendix C1 of this manual refers. 4.4.4 Bravo Sea Trial (Submarines only). Bravo Sea Trial is generally the submarine’s second underway period and first dive to Test Depth. NOTE: THE FIRST SHIP OF EACH CLASS NORMALLY CONDUCTS ITS FIRST DIVE TO TEST DEPTH DURING ALPHA TRIAL. a. Testing. (1) The tests and evolutions to be carried out following the initial tightness dive and prior to the deep dive, during the deep dive, submerged following the deep dive, and on the surface following the deep dive, are identified with Appendix F of this chapter. (2) Shutter Stall Speed. Run ahead at maximum speed allowed by SOE. Operate torpedo tube shutters and ejection pump shutters. If shutters do not open, gradually reduce speed until shutters open. This establishes “stall speed” for each shutter. b. Restrictions. As specified in paragraph 4.4.3.b of this chapter. c. Escort. As specified in paragraph 4.4.3.c of this chapter. d. Reporting Criteria. With the exception of reporting the deficiencies during the trial, reporting of the completion of Bravo Trial is not required. Daily SITREPs to the Supervising Authority and the Supervising Authority’s message concerning the completion of all trials (Volume I, Chapter 2, Appendix D1 of this manual refers) satisfies the reporting requirements. 4.4.5 Charlie Sea Trial (Submarines only). Charlie Sea Trials are conducted prior to CT. Bravo Trial retest items are also included in this trial. The standard restrictions and escort requirements as specified per paragraphs 4.4.3.b and 4.4.3.c of this chapter apply.

p. 191

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-9 4.4.6 Acoustic Trials (Platform and Radiated) (Submarines only). New construction acoustic trials, performed by the shipbuilder, are accomplished to determine, under various conditions of operation, the radiated and platform acoustic signatures of the submarine, the controlling noise offenders including those which are speed dependent, and whether or not the submarine meets its underway noise objectives. Proper operation of systems and components and the use of proper personnel quieting techniques is vital for successful acoustic measurements. Acoustic trials performed by Naval Surface Warfare Center Carderock Division (NAVSURFWARCEN CD) are used to establish the ship’s baseline signature for normal operating conditions by performing independent measurements under preset conditions of speed, depth, aspect angle, and machinery line up. It is imperative that Ship’s Force understand that this trial will determine its future operating conditions during various “patrol quiet” conditions. 4.4.7 Shock Trials. Shock Trials are designed to test the survivability characteristics of a ship under deliberate and controlled conditions. Normally scheduled for the first ship of a class just before Post Shakedown Availability (PSA); Shock Trials satisfy Congressionally mandated Live Fire Test and Evaluation requirements. Navy Shipbuilding Program Managers are responsible for the development of a management plan for the conduct of Shock Trials. 4.4.8 Acceptance Trials, Combined Trials, Final Contract Trials and Guarantee Material Inspection. a. Reference (d) tasks the INSURV with conducting an independent verification of the readiness of a newly constructed ship prior to its acceptance into Naval Service. Reference (k) states that the procedures for conducting trials and inspections must be specified by the President, INSURV. References (f) and (h) provide those procedures for submarines and surface ships respectively. References (f) and (h) are augmented by reference (a) in their application to nuclear powered ships. References (l) and (m) provide detailed information concerning the documentation of deficiencies. In addition, each Supervising Authority, TYCOM, the Naval Ships’ Technical Manual (NSTM) and reference (n) all provide additional information concerning AT, CT, GMI and Final Contract Trials (FCT). TYCOM directives are identified in the applicable TYCOM 5215 Notice. b. Prior to the acceptance and delivery of a new ship, all machinery, electronics and weapons systems installed must be subjected to ATs to determine that the installations are capable of meeting performance specifications. Depending upon the platform type, these trials are referred to as either ATs, or CTs. This independent verification of the ship’s readiness for acceptance and recommendation for fleet introduction, as specified in reference (d), is the responsibility of the President, INSURV. c. These trials are generally two part evolutions. There is an underway portion during which time the INSURV observes the performance of the ship and all equipment and systems. Upon completion of the underway portion, trial board designated equipment and associated components are disassembled for post-trial examination (the open and inspect evolution). References (f) and (h) provide amplifying information concerning this issue. d. CTs, usually the norm for submarines, are a combination of ATs and FCTs. The AT for non-submarine platforms results in a conditional acceptance primarily based on the

p. 192

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4-10 fact that the ship still requires fitting out. Submarines go through the fitting out period during the construction phase which produces a completed ready for sea vessel at delivery. The standard restrictions and escort requirements as specified per paragraphs 4.4.3.b and 4.4.3.c of this chapter apply. e. FCTs are conducted after the ship has been fully equipped, armed, made complete and ready for service. These trials are normally held just prior to PSA and prior to the end of the guarantee period. Their objective is to determine if there are any defects, failures or deterioration, other than that due to normal wear and tear, directly related to shipbuilder fault which have not been corrected or resolved. The scope of FCTs is essentially the same as AT. f. A GMI is a material inspection, conducted on submarines prior to PSA by an INSURV per reference (f). g. INSURV reports from previous ships as held by the Supervising Authority provide familiarity with problems and corrective actions already taken. In addition, these reports provide a baseline for conducting shipboard inspections and generating inputs for the PCO’s monthly progress reports.

COMUSFLTFORCOMINST 4790.3 REV D CHG 2 31 MAR 2022 I-4F-6 APPENDIX F NOTES 1. Each person involved in Sea Trials should be allowed a minimum of six hours of continuous, uninterrupted sleep during any 24-hour period encompassed by the Sea Trial. 2. Event is optional with regard to sequence. May be conducted at any time during Sea Trials and is not a prerequisite to the deep dive. If listed with initial tightness dive events, completion is not mandatory prior to proceeding with remainder of trials. 3. Those seawater systems which are not required for normal safe operation of the ship at test depth but which have been designed for and may be subjected to test depth pressure should not be subjected to submergence pressure during the initial dive to any specified depth (e.g., a blown sanitary tank). (See reference (i)). 4. At maximum safe speed, operate the rudder and planes through full throw in both directions in normal and emergency power. Time evolutions and check against design values. 5. Deep dive should be conducted using moderate speed, or as approved by NAVSEA, and constantly adjusting trim, at depths specified in reference (i), to maintain neutral buoyancy. Moderate speed must be defined as that range of speed that allows the ship to recover from a loss of stern plane control or flooding casualty. 6. Reference (i) prescribes procedures for systems operation during deep dive. 7. In the execution of any Sea Trial, whether escorted or not, submarine COs are reminded of their responsibility to communicate with escorts or shore authorities, or both, within prescribed, previously agreed upon time limits to avoid initiation of inadvertent lost contact or submarine disaster procedures. 8. Integrity of launchers or signal ejectors must be established by admitting sea pressure through equalizing lines or flooding connection and the muzzle valve or door operated before conducting operational tests. Shoot water slugs from specified launchers or signal ejectors, at specified depths, as required by the CS or CCS test program. Shoot pyrotechnics on initial dive and at test depth on the deep dive. Shooting of pyrotechnics during the initial dive must be accomplished in conjunction with the 200 foot EMBT Blow. Shooting of pyrotechnics at test depth during the deep dive must be accomplished in conjunction with the test depth EMBT blow. 9. Cycling of rudder and planes through full throw should be limited to 90% of test depth. 10. Test to demonstrate the ability of the tank to withstand external pressure. 11. The required sequence of events is initial dive, deep dive, full power run submerged, then high speed maneuverability and steep angle tests. On initial propulsion plant trials for new construction nuclear powered submarines, the deep dive will be to test depth minus 300 feet unless otherwise approved by NAVSEA or the TYCOM and reflected in the Sea Trial Agenda. 12. Run full power submerged for at least two hours. COs may schedule the full power run for four hours if deemed necessary. Operate at minimum non-cavitating depth but not to exceed 400 feet. Water depth is not limited for this event.

A Sample Page of 4760-1 Report with Representative Data B Legend and Explanation of Symbols Used in Report 4760-1 C Preparation for Guarantee Material Inspection and Final Contract Trials 5.1 PURPOSE. The purpose of this chapter is to provide a procedure to identify and document deficiencies found in new construction ships. This chapter focuses on the period from initial Acceptance Trials (AT) until the termination of funding responsibility under the Shipbuilding and Conversion, Navy (SCN) appropriation. Proper management of these deficiencies is necessary to ensure: a. Final settlement of the construction contract with the shipbuilder. b. Correction of the maximum number of shipbuilder responsible deficiencies under terms of the construction contract. c. Correction of the maximum number of government responsible deficiencies under the SCN appropriation. d. Identification of all new construction deficiencies which must be corrected subsequent to the guarantee period under appropriations other than SCN, and identification of improvement items which have class application. Deficiency items not adjudicated prior to Combined Trials (CT) and the Guarantee Material Inspection (GMI) for submarines or during ATs and Final Contract Trials (FCT) for all other ships are identified to the Navy by the Board of Inspection and Survey (INSURV). Additional items are identified during Naval Sea Systems Command (NAVSEA) Acoustic Trials, Underwater Electromagnetic Trials, Combat System Certification Trials (CSCT) and by the Commanding Officer (CO) of the ship during the contract guarantee period and reported to the Supervising Authority. 5.2 DEFICIENCY CORRECTION. Deficiencies are addressed in terms of three general categories. The procedure for initiating corrective action for a deficiency is determined by the category. 5.2.1 Government Responsible Items. The obligation and work limiting date for all shipbuilding programs under the SCN appropriation will normally be at the end of the 11th month following completion of the fitting out period. For submarines, the fitting out period ends at delivery. Government responsible work accomplished in support of a new construction ship and funded

CHAPTER 5

p. 219

COMUSFLTFORCOMINST 4790.3 REV D CHG 1 15 JAN 2021 I-5-2 under SCN is limited to work which can be completed prior to the end of this 11-month period. Authorization for correction of non-reactor plant government responsible deficiencies is provided by the Navy Shipbuilding Program Manager based on a priority assignment by the ship and recommendations from the Type Commander (TYCOM). Authorization for correction of reactor plant government responsible deficiencies is provided by NAVSEA Nuclear Propulsion Directorate (08). 5.2.2 Shipbuilder Responsible Items. Construction contracts with private industrial activities contain a guarantee clause. The rights of the government concerning deficiencies identified during the guarantee period are set forth in the contract. Deficiencies must be identified and reported to the shipbuilder and cognizant government agencies prior to the end of the guarantee period in order for corrective action to be established. Correction of deficiencies designated shipbuilder responsible can be accomplished during any subsequent period that the ship is made available to the shipbuilder. Availability of the ship is usually limited to the Post Shakedown Availability (PSA), except under special circumstances when immediate corrective action prior to PSA is required to permit the ship to meet operational commitments. The ship may also be made available to the shipbuilder after PSA to permit follow-up corrective action on shipbuilder responsible deficiencies identified during the guarantee period but not satisfactorily corrected during PSA. 5.2.3 Recommended Changes in Characteristics, Design Specifications, or Plans. Improvements to the ship recommended by INSURV will be investigated by the Navy Shipbuilding Program Manager. Action, as appropriate, will be initiated by a government approved change. This change may be in the form of a Field Modification Request (FMR), Headquarters Modification Request (HMR), Ship Change, Strategic Systems Programs Alteration (SPALT), Service Change and Field or Engineering Change Proposal. Changes of this nature usually have application to more than one ship of the class. Improvements to the ship recommended by Ship’s Force should be forwarded by the CO per Volume VI, Chapter 3 (submarines) or Volume VI, Chapter 36 (surface force ships and aircraft carriers), as appropriate, of this manual to the Navy Shipbuilding Program Manager via the Supervising Authority. 5.3 REQUIRED REPORTS. The responsibility for ensuring deficiencies are corrected rests jointly with the CO, the Supervising Authority and the Navy Shipbuilding Program Manager. The method of corrective action varies with the type of deficiency and may involve the coordinated action of several activities. In order to effectively prosecute each deficiency, special reporting and handling procedures are necessary. The Ship’s Maintenance Data System must be implemented not later than delivery per reference (a). This will provide a smooth transition into the appropriate ship and shore based data management systems and permit Maintenance and Material Management (3-M) documentation of all INSURV deficiencies for use with the Consolidated Report. The Consolidated Report provides follow-up action on all deficiencies and minimizes administrative effort. a. Consolidated Report. A Consolidated Report, compiled by the Navy Shipbuilding Program Manager, combines into one document the screening actions, reports of completed actions and significant information listed (as applicable): (1) AT or CT INSURV Report. (2) FCT or GMI INSURV Report.

(b) List of INSURV GMI or FCT items: Prepared by the ship per Appendix C of this chapter immediately following the GMI or FCT for use by NAVSEA at the GMI or FCT Card Conference. The Navy Shipbuilding Program Manager will distribute a finalized GMI or FCT list following the GMI or FCT Card Conference. (2) Part C-I, C-II, C-III, D and F: Prepared and distributed by the Navy Shipbuilding Program Manager. (3) Part E: Prepared by the ship as discussed in section 5.6 of this chapter. d. Reporting. (1) Thirty days after delivery, the ship will submit marked up copies of Part B indicating the priority assignment of each uncorrected CT or AT deficiency (Navy Shipbuilding Program Manager, TYCOM, Immediate Superior in Command (ISIC), Supervising Authority). (2) The Navy Shipbuilding Program Manager will prepare and distribute marked up copies of Parts C-I, C-II, C-III, D and F as the information becomes available. (3) Priority assignment for Part B deficiencies (including review of all uncorrected CT or AT deficiencies) is determined at the GMI or FCT Card Conference. Marked up copies are retained by all participants. (Navy Shipbuilding Program Manager, TYCOM, ISIC, Ship, Supervising Authority). (4) The ship will report deficiencies discovered after GMI or FCT and before the end of the SCN period per section 5.6 of this chapter. (5) Deficiencies listed in the Consolidated Report which are corrected by Forces Afloat are to be reported in writing to the Navy Shipbuilding Program Manager with copies to the TYCOM, the Supervising Authority as appropriate, and the scheduled PSA activity. This report will normally be submitted by the ship at the end of a refit or maintenance period. Negative reports are not required. (6) The ship will submit a marked up copy of the Consolidated Report to the TYCOM; copy to the ISIC, Navy Shipbuilding Program Manager, Supervising Authority, Submarine Maintenance Engineering, Planning and Procurement (SUBMEPP) Activity (for submarines), Surface Maintenance Engineering, Planning Program (SURFMEPP) (for surface force ships) and the President of the INSURV Board thirty days after PSA or at the end of the guarantee period, whichever is later. This report will indicate the final status of all deficiencies identified during the guarantee period. 5.4 COMBINED TRIALS or ACCEPTANCE TRIALS. The CT or AT is scheduled by the Supervising Authority and conducted by the INSURV Board. The Supervising Authority in

p. 222

COMUSFLTFORCOMINST 4790.3 REV D CHG 1 15 JAN 2021 I-5-5 conjunction with the ship’s CO will present to the INSURV Board known deficiencies which require correction. 5.5 GUARANTEE MATERIAL INSPECTION or FINAL CONTRACT TRIALS. GMIs or FCTs are scheduled by the TYCOM and conducted by the INSURV Board after shakedown, prior to the end of the guarantee period. These inspections or trials provide a formal evaluation of the material condition of each newly constructed ship after limited service. GMIs or FCTs are conducted sufficiently in advance of PSA to allow “lead time” for the procurement of material and the advanced planning required for the correction of deficiencies during the availability. The CO will present the ship’s material status to the INSURV Board following the guidance in Appendix C of this chapter. GMIs are conducted for submarines; all other ships will undergo an FCT. 5.6 POST DELIVERY DEFICIENCY ITEMS. The CO is responsible for reporting deficiencies not otherwise identified by INSURV, until the end of the SCN period per the following procedures. By using the same format for PDDI reporting as for INSURV items and by extending the use of the Consolidated Report to include these items, the same management attention is afforded to all construction deficiencies. a. The following types of problems should be reported as PDDIs: (1) Recurring failures in a piece of equipment or machinery such that the reliability is considered unsatisfactory. (2) Major equipment or component malfunction which requires outside assistance to correct (vendor or industrial activity). (3) Symptoms of major machinery problems which require investigation to determine the extent of the problem. (Improper temperatures, pressures, leakage, vibration, noise, etc.). (4) Insufficient supply support for specific equipment or machinery based on operational experience. Allowance deficiencies reported as PDDIs should be supplemented by submission of Allowance Change Requests or Configuration Change Reports as appropriate. (5) Excessive or accelerated wear, erosion, or corrosion determined through inspection. (6) Improper bonding of preservation on surfaces that must be protected. (7) Any casualty which results in a Casualty Report (CASREP). Insert an amplification data set immediately after the Parts Identification data set consisting of “AMPN/PDDI: ___- ___//”, ensuring that the CASREP includes all appropriate PDDI addressees. A separate PDDI must also be submitted. (8) Identification of any condition or defect which requires a Departure from Specification request. (9) Improper alignment, clearance, or resistance to ground which indicates an unaccounted for change from baseline data.

p. 223

COMUSFLTFORCOMINST 4790.3 REV D CHG 1 15 JAN 2021 I-5-6 (10) Significant internal and external valve leakage. (Primary, seawater, steam, air, hydraulics, etc.). (11) Any significant AT or CT deficiency item reported corrected which has recurred. Refer to the AT or INSURV number in the text of the deficiency description. (12) Any AT or CT deficiency item reported corrected by the shipbuilder which is not considered by the ship to be complete. Refer to the AT or INSURV number in the text of the deficiency description. NOTE: DEFICIENCIES AND MATERIAL PROBLEMS WHICH ARE CORRECTED BY SHIP’S FORCE WITHOUT ASSISTANCE SHOULD NOT BE REPORTED AS PDDIs. b. Reporting. (1) Between delivery and GMI or FCT, uncorrected deficiencies of the nature described in paragraph 5.6 of this chapter should be documented in the Current Ship’s Maintenance Project (CSMP) and presented to the INSURV Board for consideration during GMI or FCT. (2) Problems requiring corrective action prior to PSA, or of such significance that planning will have to commence as early as possible, should be reported by OPNAV 4790/2K without delay. The OPNAV 4790/2K must contain the sequential identification number of the PDDI and a brief description of the problem being reported. Multiple PDDIs per report are encouraged. Items reported by OPNAV 4790/2K should be included in the next regular PDDI report. The OPNAV 4790/2K should also be sent by message, or e-mail where appropriate, and must be addressed to the Supervising Authority, with information copies to the Navy Shipbuilding Program Manager, TYCOM (N40), the ISIC, and NAVSEA 08 (for items with nuclear cognizance). (3) Routine PDDIs must be reported by OPNAV 4790/2K and summarized at least monthly after the GMI or FCT.

COMUSFLTFORCOMINST 4790.3 REV D CHG 1 15 JAN 2021 I-5B-1 APPENDIX B APPENDIX B LEGEND AND EXPLANATION OF SYMBOLS USED IN REPORT 4760-1 1. Each activity will enter in the applicable column the appropriate symbol to indicate status, position, priority, responsibility or authorization for each item. 2. Extra pages may be added to the package as necessary to provide history, results of investigations or comments to clarify the position or the item itself. 3. The action taken for each item in each of the columns from the “N/S Action” column through the “PSA” column will be an integrated action by all concerned following INSURV CT or AT, GMI or FCT, and PSA related conferences. 4. The following is a brief description of the purpose of each column: a. Column “N/S Action” - Indicates Navy Shipbuilding Program Manager assignment of responsibility. No government SCN funded work is authorized in this column. Authorization of work will be as stated under the “PSA” column for each line item in the work package. b. Column “K” - Column “K” is used to indicate the position of the shipbuilder for an item indicated in column “N/S Action” as being the responsibility of the shipbuilder to correct. The shipbuilder may prepare insert pages for comments as appropriate. A rationale is to be provided for all items not accepted (marked “KZ”) by the shipbuilder. c. Column “SOS” - This column is used to indicate the position of the Supervising Authority for each of the items as feasible but especially for those items on which the shipbuilder has responded in column “K”. d. Column “Ship” - This column is used by the ship to indicate the status or action desired for each item still considered open, including a priority assignment regardless of the responsibility or action indicated by INSURV or assigned by the Navy Shipbuilding Program Manager or reported corrected by the Supervising Authority. Comments from Ship’s Force providing further information and clarification as insert pages are especially helpful in planning correction of any item. e. Column “TY” - This column indicates the position of the TYCOM on the priority assignment of the ship. f. Column “PSA” - This column is used by NAVSEA. Authorization of SCN funded work appears only in this column. g. Column “Final” (Ship and Supervising Authority) - This column is used to indicate the final status of each deficiency at the end of the SCN funded period. This column may be used by the shipbuilder to report to the Supervising Authority the status of deficiencies at the end of the guarantee period. This column is used by Supervising Authority to provide the final status of all authorized work (government and shipbuilder) as reported by the shipbuilder at completion of PSA. This information should be used as a portion of the Departure Report which is to be forwarded to the Navy Shipbuilding Program Manager not later than 50 days following the end of the

A Major Funding Milestones During Construction or Conversion B Post Shakedown Availability Planning Events Milestone Schedule C Summary of Major Milestones for Post Shakedown Availability 6.1 PURPOSE. a. Post Shakedown Availability (PSA) is an industrial activity availability assigned to correct deficiencies found during the shakedown cruise or to accomplish other authorized improvements. PSAs are scheduled to commence after delivery and to be completed prior to the Shipbuilding and Conversion, Navy (SCN) obligation work limiting date. This date occurs at the end of the 11th month after the month in which the Fitting-Out Period completed for surface units or at the end of the 11th month after the month in which delivery occurs for submarines. Appendix A of this chapter, taken from reference (a), reflects the Major Milestones during Construction related to funding. Funding guidelines for PSA are outlined in reference (b). b. The length of time designated for PSAs will vary dependent on the platform. Acceptance Trial (AT), Final Contract Trial (FCT), Combined Trial (CT) and Guarantee Material Inspection (GMI) related deficiencies constitute the majority of the PSA workload. Navy Shipbuilding Program Manager planned, authorized and funded modifications may also be included. 6.2 PLANNING AND EXECUTION. The events leading to a successful completion of PSA involve several activities and a variety of actions and reports. Appendix B of this chapter outlines the schedule of PSA planning events. 6.3 TRIALS, INSPECTIONS AND CREW CERTIFICATION. For nuclear and Surface Force Ships, Appendix C of this chapter provides a summary of major milestones required for PSA. For submarines, Appendices BC and CC in Volume II, Part I, Chapter 3 of this manual provide a summary of major milestones. 6.4 SEA TRIALS. Sea Trials are required to test work completed during PSA. The mandatory submarine requirements for PSA Sea Trials are identified in Volume II, Part I, Chapter 3 of this

CHAPTER 6

COMUSFLTFORCOMINST 4790.3 REV D 16 Oct 2019 I-6-2 manual. Volume II, Part I, Chapter 3, Appendix K of this manual provides a list of the minimum tests to be performed during Sea Trials for Surface Force Ships. The industrial activity must include at least two days in the availability for Sea Trials. The industrial activity must prepare an agenda for Sea Trials conducted after a PSA. Extensions or reductions of the Sea Trial period may be granted where warranted by the scope of work accomplished. Where an extension of Sea Trial and a change in the availability schedule is required, requests for such extensions must be submitted by the industrial activity to the Type Commander (TYCOM) as early as practical. All deficiencies resulting from Sea Trials must be satisfactorily resolved prior to completion of the availability. If no Sea Trial deficiencies are found, the availability may be completed with TYCOM concurrence at the completion of Sea Trials. 6.5 DEFICIENCY CORRECTION PERIOD. A deficiency correction period will be scheduled after Sea Trials and prior to PSA completion. The scheduled length of this deficiency correction period will be determined by the type and magnitude of the remaining deficiencies. 6.6 PERIOD FOLLOWING POST SHAKEDOWN AVAILABILITY. Depending on the PSA contract, the industrial activity will normally guarantee work accomplished during an availability for a period of 90 days from the completion of the availability. This does not include responsibility for malfunctioning machinery and equipment due to normal wear, improper adjustment, or tuning by Ship’s Force and failure of limited life components. Ship’s Force is required to report guarantee items to the industrial activity prior to the guarantee period expiration date. If operational commitments prohibit reporting prior to the 90-day period, the ship should report problems as soon as operations permit. A message is the preferred method of reporting these items. The message outlining specific deficiencies should be submitted to the Supervising Authority with a copy to the TYCOM, the Immediate Superior in Command (ISIC) and the Navy Shipbuilding Program Manager who will pass a copy to Naval Sea Systems Command (NAVSEA) 04, and to NAVSEA 08 for nuclear cognizant issues. Additionally, any Casualty Reports (CASREP) submitted during the guarantee period must also be addressed to the Supervising Authority and the Navy Shipbuilding Program Manager with passing instructions to NAVSEA 04, and to NAVSEA 08 for nuclear cognizant issues.
