Fleet Replacement Squadrons (FRS) for fixed wing carrier based aircraft use the CVW style tail code.
Naval Air Force Pacific Fleet carrier based fixed wing aircraft FRS use tail code NJ and Naval Air Force Atlantic Fleet carrier based fixed wing aircraft FRSs display tail code AD.
Light transport aircraft assigned to Marine Corps Air Stations use a two place tail code consisting of a number 5 followed by a letter unique to each Marine Corps Air Station.
