Based upon the current aviation transition strategy, there will no longer be a requirement for USMC Naval Flight Officers (NFOs) after FY19. The F/A-18D WSO MOS (7525) and the EA-6B ECMO MOS (7588) will be programmed to end as a primary MOS at a date TBD. Marine Aviation is actively engaged with Manpower and Reserve Affairs to ensure officer end strength and accessions provide flexibility and professional opportunities for remaining NFOs, while capitalizing on NFO MOS expertise. The sundown plan will include both increased NFO-to-pilot transitions and alignment of the electronic warfare and missions systems expertise in the NFO community with emerging requirements in the UAS Family of Systems (FoS), manned ISR initiatives and the F-35B program.
