F/A-18 Hornet Military Occupational Specialties Personnel Transition
This MARADMIN outlines the transition plan for F/A-18 Hornet maintenance personnel as the Marine Corps phases out F/A-18 C/D operations and transitions to an all-5th Generation tactical aircraft fleet. Enlisted Marines in six F/A-18 maintenance MOSs (6217, 6227, 6257, 6287, 6317, and 6337) will be reclassified into new MOSs based on regional deactivation timelines, with priority given to transitioning into F-35 maintenance positions. The transition will occur in phases by region: Eastern Region by August 1, 2028, Western Region by August 1, 2029, and Reserve Region by August 1, 2030.
Issued: May 4, 2026
1. Purpose. As outlined in Ref (a) F/A-18 C/D Hornet (VMFA) Plan, Manpower and Reserve Affairs (M&RA) is transitioning the F/A-18 maintenance population in accordance with Marine Aviation's TACAIR transition plan and force modernization objectives. 2. Background. Marine Aviation is transitioning to an all-5th Generation Tactical Aircraft Fleet and modernizing all other aspects of the ACE to be postured to fight tonight against our nation's adversaries. The phased deactivation of F/A-18 C/D Hornet operations is a critical element of this effort. 3. This MARADMIN is applicable exclusively to enlisted Marines in the following Military Occupational Specialties (MOS): 6217 Fixed Wing Aircraft Mechanic F/A-18, 6227 Fixed-Wing Aircraft Power Plants Mechanic F404 F/A-18, 6257 Fixed Wing Airframe Mechanic F/A-18, 6287 Fixed Wing Aircraft Safety Equipment Mechanic F/A-18, 6317 Aircraft Comm/Nav/Radar Systems Technician F/A-18, and 6337 Aircraft Electrical Systems Technician F/A-18. 3.a. Retention and promotion opportunities in the MOSs listed above will be tied to the continued operation of F/A-18 units in each region. By Fiscal Year (FY) 30, with final Hornet unit deactivation, no further promotion or retention opportunities will exist for the remaining F/A-18 maintenance population. Those Marines serving outside the F/A-18 MOS, for example on Special Duty Assignment, will be given an Intended MOS (IMOS) for F-35 and will remain eligible for promotion. At present, other MOSs do not require the use of force shaping measures as part of the 2026 Marine Aviation Plan. Manpower Management Enlisted Assignments (MMEA) will publish guidance if subsequent phases of the 2026 Marine Aviation Plan require force shaping for Marines in additional MOSs. 3.b. First Term Alignment Plan (FTAP) Marines who are within their reenlistment cohort and are considering a lateral move remain eligible under normal retention processing procedures. 3.c. FTAP Marines who are not within their reenlistment cohort and are considering a lateral move, will first be considered for transition to F-35 maintenance community MOSs with comparable skill sets in keeping with Ref (a) via MOS reclassification. 3.d. Subsequent Term Alignment Plan (STAP) Marines, regardless of reenlistment cohort, who submit for lateral move will be processed, with priority consideration given to transition into F-35 maintenance community MOSs with comparable skill sets in keeping with Ref (a). 4. MOS Reclassifications. In accordance with Ref (a), Marines in MOS 6217, 6227, 6257, 6287, 6317, and 6337 who are not stabilized for deployment, pending orders, approved for lateral move, or separation due to voluntary actions will be reclassified into a new MOS. Additionally, these MOS reclassifications will be based solely on the needs of the Marine Corps, regardless of remaining contract time, by the following regional deadlines: 4.a. Eastern Region (MAG-31/MCAS Beaufort). Not later than 1 August 2028, or upon cessation of F/A-18 operations at MCAS Beaufort. After this date, no F/A-18 maintenance billets will remain at this location. 4.b. Western Region (MAG-11/MCAS Miramar). Not later than 1 August 2029. This is aligned to the completion of active component Hornet operations aboard MCAS Miramar. 4.c. Reserve Region (MAG-41/NAS JRB Fort Worth). Not later than 1 August 2030. This is aligned to the completion of reserve component Hornet operations aboard NAS JRB Fort Worth. 4.d. Marines at the rank of Sergeant and below, or who are subject to reclassification, will be processed in accordance with established procedures per Ref (b). 4.e. Senior enlisted Marines (Staff Sergeants and above) will be processed in accordance with the applicable guidelines for their ranks per Ref (b). 4.f. Marines serving outside the regions listed in paragraphs 4.a through 4.c are encouraged to contact the F-35 Monitor prior to receipt of follow-on assignment orders, or no later than six months before the end of their unit deactivation, whichever occurs first. 4.g. Marines within the MOSs listed in paragraph 3 who desire to remain and deactivation their current units are authorized to extend their current End of Active Service (EAS) to align with formally established unit deactivation dates, once published via Marine Corps Bulletin (MCBUL) promulgated by the Total Force Structure Division (TFSD). Marines requesting for extension must be eligible in accordance with retention guidelines. 5. Coordinating Instructions. Marines are highly encouraged to lateral move from F/A-18 MOSs to F-35 MOSs. The MOS Reclassification process will commence during the regional transition year unless otherwise coordinated per paragraph 5.d in this message. Affected Marines will be notified of their new PMOS or IMOS on or about 30 September of that year. 5.a. Manpower Management (MM), will conduct the MOS Reclassification process in phases corresponding to the deadlines in paragraph 4. 5.b. New PMOS assignments and subsequent orders will be based solely on the needs of the Marine Corps. Each Marine's situation will be reviewed on a case‐by‐case basis, to include opportunities for transition to F-35 maintenance or other critically short MOSs. 5.c. Marines receiving a new PMOS as a result of MOS reclassification will not incur any additional obligated service after completion of their new PMOS schooling. 5.d. Due to operational requirements, the milestones in paragraph 4 may be adjusted earlier or later than the initial estimates. Any changes will be coordinated between MM, TFSD, Marine Aviation, and fleet leadership in accordance with Ref (a). 6. This MARADMIN is applicable to the Active Component for the MOSs listed in paragraph 3. 7. Release authorized by MajGen Fridrik Fridriksson, Director, Manpower Management Division.
