COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 III-2-4 2.3 COMMON MAINTENANCE FACILITIES - ALL AREAS OF RESPONSIBILITY. The following types of maintenance facilities are common to all AORs and provide the services indicated. 2.3.1 Afloat Fleet Maintenance Activities. 2.3.1.1 Capabilities. For purposes of this volume, the Repair Department of a submarine tender will be referred to as Afloat Fleet Maintenance Activity (AFMA). AFMAs offer the broadest range of industrial capabilities of any afloat Navy activity. AFMAs are capable of repairs in all areas (e.g., hull, mechanical, electrical, electronic and ordnance equipment). Where there are shortfalls in shipboard expertise, AFMAs will be augmented by outside resources. 2.3.1.2 Workload. Maintenance Managers, Operational Commanders and AFMA Commanding Officers will maximize use of deployed AFMA Fly Away Teams (FAT), deployed or otherwise. 2.3.1.3 Afloat Fleet Maintenance Activity Fly Away Team. FATs provide a unique method of rapid deficiency correction which stresses mobility, initiative and maximization of resource utilization. AFMA FATs must be used for CASREP correction and technical assistance for ships not collocated with the AFMA. AFMA FATs are tasked by the Maintenance Manager only after the following conditions have been established: a. Casualty is not correctable by any sh ip, element or unit of the Strike Force Intermediate Maintenance Activity (SFIMA). b. Ship will provide parts or FAT can carry all required parts. Each AFMA will establish procedures to enable the deployment of FATs within hours of receiving tasking. The procedures will include pre-designation of FAT members, rapid preparation for travel orders, travel regulation briefings, advances in travel funding, area briefings, and area clearance messages as appropriate. 2.3.1.4 Fly Away Team Funding. FAT funding will be provided following Fleet direction. 2.3.1.5 Afloat Fleet Maintenance Activity Tasking. Tasking AFMA for performance of VRs, FAT assistance or other availabilities will be: Maintenance Brokers for Fifth, Sixth and Seventh Fleet assigned units will request AFMA support and availability periods, via CTF 74, who will directly task AFMAs located in Guam. For AFMAs in other locations in Fifth, Sixth and Seventh Fleet, Maintenance Brokers will request AFMA support and availability periods via the CTF (54, 69, 74) exercising Operational Control of the tender. The CTF exercising Operational Control will directly task the appropriate tender. CTF 54, 69, 74 or COMSUBRON 15, as applicable, must provide the required support based on AFMA operational considerations and resource limitations (e.g., manpower and materials). 2.3.2 Strike Force Intermediate Maintenance Activity. 2.3.2.1 Mission. The mission of the SFIMA is to provide a first response to units needing assistance with maintenance candidates beyond their capability to correct while deployed, at sea, or away from regular support facilities. Requests for an impending service or equipment requirement will be processed through the Strike Force Commander, Ship’s Maintenance Manager and the Aviation Intermediate Maintenance Department Officer via a Naval Message or SIPRNET E-mail. This will permit efficient work scheduling, advanced personnel planning and minimize disruption to other scheduled jobs. All work for the engineering repair shops will be

COMUSFLTFORCOMINST 4790.3 REV D CHG 3 07 Nov 2023 III-2-5 conducted and coordinated by the Ship’s Maintenance Manager through the repair officer and repair division technicians. The repair officer will coordinate all efforts through the quality assurance program, planning and estimating, non-destructive testing and repair technicians. All SFIMA work requires an individual work candidate entry by the repair work center into the maintenance data system. This will account for all repair man-hours and material through the 3- M up-line reporting process. 2.3.2.2 Policy. With the exception of SUBSAFE, Strike Force maintenance and repair actions are limited only by the procedures and guidelines contained in reference (b) and in the Quality Maintenance section, Volume V, Part I, Chapter 2 of this manual. The Strike Force is not authorized to perform SUBSAFE work. 2.3.2.3 Applicability. This paragraph applies to all Forces, Ships, Units and Detachments deploying as a cohesive force. The SFIMA, Volume III, Chapter 6 of this manual, describes policies, provides governance and reporting requirements, and assigns roles, responsibilities, and actions necessary for Strike Group units. 2.3.3 Regional Maintenance Center. RMCs provide contract maintenance support in all ports when assigned. RMC functions include shipcheck of screened work packages, specification writing, contract technical representation and Quality Assurance of contracted work. Working closely with FLC-Naval Regional Contracting Detachment (NRCD), which performs the Primary Contracting Officer functions; RMCs ensure all work accepted for accomplishment as VR is completed on time and per specifications. RMCs are located in Naples, Bahrain and Japan. 2.3.4 Regional Maintenance Center and Technical Assistance. The RMC Technical Support mission is to promote shipboard self-sufficiency per reference (a). This is carried out by providing system and equipment Subject Matter Experts to assist and train Ship’s Force in casualty prevention and correction. When the assistance required is not resident in the AOR, the responsible RMC will arrange technical assistance from other sources. Each RMC publishes a list of their organic technical capabilities. RMCs can request additional resources to provide assistance per Volume VI, Chapter 2 of this manual. RMCs can provide assistance for all non- nuclear shipboard systems. Additional details on FTA are available in Volume VI, Chapter 2 of this manual and reference (a). 2.3.5 Naval Regional Contracting. FLC-NRCD Naples and Singapore, provide contracting in support of AFLOAT and ASHORE activities. In support of afloat maintenance, FLC-NRCDs can perform all pre- and post-award contracting functions. They execute a variety of contract actions to support ship maintenance such as: issue Master Agreements for Repair and Alterations of Vessels (MARAV); place calls against Blanket Purchase Agreements, award Contracts or Purchase Orders; and compete job orders among MARAV holders. Please note that establishment of a MARAV only pre-qualifies industrial activities to accomplish Navy work which streamlines the procurement process. Being a MARAV holder does not guarantee the industrial activity can accomplish all types of work. 2.4 UNIQUE MAINTENANCE FACILITIES - COMMANDER, UNITED STATES NAVAL FORCES, EUROPE-COMMANDER, UNITED STATES NAVAL FORCES, AFRICA- COMMANDER, SIXTH FLEET AREA OF RESPONSIBILITY.
