11 September 1953: At Naval Ordnance Test Station China Lake, the experimental Philco/General Electric XAAM-N-7 “Sidewinder” heat-seeking air-to-air missile scored its first “hit” when it passed within 2 feet (0.6 meters) of a radio-controlled Grumman F6F-5K Hellcat. The missile was fired from a Douglas AD-4 Skyraider flown by Lieutenant Commander Albert Samuel Yesensky, United States Navy, the Officer-in-Charge (OIC) of Guided Missile Unit SIXTY-ONE (GMU-61).

The Sidewinder was later redesignated AIM-9. It entered service in 1956 as the AIM-9B and has been a primary fighter weapon for 60 years.

The AIM-9 Sidewinder is a Mach 2.5+ missile, equipped with an infrared seeker to track the heat signature of the target aircraft. (The Hellcat drones used in the early test had flares mounted on the wingtips to give the experimental missile a target).
The current production version, AIM-9X Block II, is produced by Raytheon Missile Systems, Tucson, Arizona. It is 9 feet, 11 inches long (3.023 meters), 5 inches in diameter (12.70 centimeters), and weighs 188 pounds (85 kilograms). The warhead weighs 20.8 pounds (9.4 kilograms). The missile’s range and speed are classified. At current production levels, the average cost of each AIM-9X is $420,944 (FY 2015 cost). Block III development was cancelled for FY 2016.

NOTC China Lake is now designated as Naval Air Weapons Station (NAWS) China Lake. It is located approximately 55 miles (88 kilometers) north-northeast of Edwards Air Force Base in the high desert of Southern California.

21 August 1956: At 40,000 feet (12,192 meters) over Naval Ordnance Test Station China Lake, near Ridgecrest, California, Commander Robert Wilks Windsor, Jr., United States Navy, flew a production Chance Vought Aircraft F8U-1 Crusader, Bu. No. 141345, to 1,015.428 miles per hour (1,634.173 kilometers per hour)—Mach 1.54—over a 15 kilometer (9.3 miles) straight course. This established a new National Aeronautic Association U.S. national speed record, breaking the previous record set by a North American Aviation F-100C Super Sabre two years earlier by 193.16 miles per hour (310.86 kilometers per hour).

F8U-1 Bu. No. 141345 was the twelfth production Chance Vought F8U-1 Crusader. It was a single-place, single-engine turbojet-powered air superiority day fighter designed to operate from the United States Navy’s aircraft carriers.
The F8U-1 (redesignated F-8A in 1962) was 54 feet, 3 inches (16.535 meters) long with a wingspan of 35 feet, 8 inches (10.770 meters) and overall height of 15 feet, 9 inches (14.801 meters). With the wings folded for storage, the span is 22 feet, 6 inches (6.858 meters). The wings were swept aft 42° at ¼-chord.
The swept wing is placed high on the fuselage and its angle of incidence is adjustable in flight. The wing has a total area of 375 square feet (34.84 square meters) and has a “dog tooth” leading edge, extending 1 foot, 0.7 inches (0.323 meters). The leading edges are swept aft to 47° (42° at ¼-chord), and there is 5° anhedral. The horizontal stabilator is placed lower than the wings. Its leading edge is swept aft to 50° and it has 3° 25′ dihedral.
The empty weight of the F8U-1 was 15,513 pounds (7,037 kilograms) with a maximum takeoff weight of 27,500 pounds (12,474 kilograms).
The F8U-1 is powered by a single Pratt & Whitney J57-P-4 engine. The J57 was a two-spool, axial-flow turbojet engine with a 16-stage compressor section (9 low- and 7-high-pressure stages) and a 3-stage turbine section (1 high- and 2 low-pressure stages). Its Normal (continuous) rating is 8,700 pounds of thrust (38.70 kilonewtons) at 5,780 r.p.m. The Military Power rating is 10,200 pounds (45.37 kilonewtons) at 6,100 r.p.m., and it can produce 16,000 pounds (71.17 kilonewtons) at 6,100 r.p.m. with afterburner. The J57-P-4 is 20 feet, 10 inches (6.35 meters) long, 3 feet, 5 inches (1.041 meters) in diameter, and weighs 4,860 pounds (2,205 kilograms).
The F8U-1 had a maximum speed of 637 knots (733 miles per hour/1,180 kilometers/hour) at Sea Level, and 880 knots (1,013 miles per hour/1,630 kilometers per hour) at 35,000 feet (10,668 meters). Its service ceiling is 42,300 feet (12,893 meters), and it has a combat ceiling of 51,500 feet (15,697 meters) with afterburner. The airplane’s combat radius is 310 nautical miles (357 statute miles/ kilometers)and the combat range is 1,150 nautical miles (1,323 statute miles/2,130 kilometers) at 494 knots (568 miles per hour/915 kilometers per hour)and 42,100 feet (12,832 meters).

The F8U-1 was armed with four Colt Mk. 12 20 mm cannon with 500 rounds of ammunition, and two AIM-9 Sidewinder infrared-homing air-to-air missiles. It could also carried thirty-two 2.75-inch Folding Fin Aerial Rockets (FFAR) internally.
Commander Windsow was a Navy test pilot who carried out much of the F8U test program, including the aircraft carrier qualifications aboard USS Forrestal (CVA-59).
Bu. No. 141345 was assigned to the Pacific Missile Test Center (PMTC), NAS Point Mugu, California, in 1961. It was converted to an F-8D, but was withdrawn from service in 1964.
Chance Vought built 1,213 F-8 Crusaders. 318 were the F8U-1 variant. Crusaders were in service with the United States Navy for 30 years.
