The McDonnell F-101 Voodoo is a supersonic jet fighter designed and produced by the American McDonnell Aircraft Corporation.

Development of the F-101 commenced during the late 1940s as a long-range bomber escort (then known as a penetration fighter) for the United States Air Force's (USAF) Strategic Air Command (SAC). It was also adapted as a nuclear-armed fighter-bomber for the USAF's Tactical Air Command (TAC), and as a photo reconnaissance aircraft based on the same airframe. On 29 September 1954, it performed its maiden flight. The F-101A set a number of world speed records for jet-powered aircraft, including fastest airspeed, attaining 1,207.6 miles (1,943.4 km) per hour on 12 December 1957.
