 The US Navy's Fighter Weapons School established in 1969 at Miramar Naval Air Station in California, better known as Top Gun, was tasked with supplying the USN with trained jet pilots for aerial combat missions over the skies of North Vietnam.From 25 January through 28 April 1971 a batch of "Maneuverability Augmentation System for Tactical Air Combat Simulation" (MASTACS) systems were modified onto existing US Navy "BQM-34A" drones (UAVs).These UAVs were test flown to evaluate their maneuvering characteristics, which were deemed good.
