Reserve Fleet Composite Squadron (VC) 12 "Fighting Omars" used this dark, 1963 built, A-4E Skyhawk. VC-12 used the JY tailcode, but this was not carried here. On 16 Jul'93, the squadron flew their last mission with the A-4 and transitioned a year later to the F/A-18A/B Hornet. VC-12 provided adversary training to East Coast Navy air wings. This A-4E was already retired to AMARC from Jan'78 to Jul'80 with inventory code 3A523, but returned to operational service. After VC-12 got rid of their A-4s, it was moved to the National Museum of Naval Aviation at Penscacola.
