Composite Squadron (VC) Twelve was the Navy's first Reserve Fleet Composite Squadron. The squadron used the single seat A-4E/F and dual seat TA-4J Skyhawks and was assigned the support mission with air intercept and dissimilar air combat maneuvering (ACM) training for Atlantic and Pacific fleet units. This near black Skyhawk used JY as tailcode (not visible) in 1987 (later on the squadron was redesgnated VFC-12 and used tailcode AF) and was stored at AMARC in August 1993.
