Douglas F4D Skyray
 The Douglas F4D Skyray (later redesignated F-6 Skyray) was an American carrier-based supersonic fighter/interceptor built by the Douglas Aircraft Company. Although it was in service for a relatively short time and never entered combat it was notable for being the first carrier-launched aircraft to hold the world's absolute speed record at 752.943 mph and was the first United States Navy and United States Marine Corps fighter that could exceed Mach 1 in level flight.
