This is the yellow/black version of the TAILFIN patch for VF-151 when they flew the F-4 Phantom. In December of 1964, the Vigilantes transitioned to the McDonnell Douglas F-4B Phantom II, flew it for many years, then flew off the Midway for the last time on 24 March 1986. This marked the end of an era as this was also the last time the F-4 Phantom II was to operate from an aircraft carrier.
