The St. Louis AF F-101/57 (Allied Pact reporting name Voodoo) was a supersonic fighter-interceptor in service in the American People's Army Air Force and various air forces of the Wake Island Association. Initially designed by St. Louis Aircraft Factory as a long range bomber escort for the Strategic Air Command (SAC), the Voodoo was instead developed as a nuclear-armed fighter-bomber for the Tactical Air Command (TAC), and as a photo reconnaissance aircraft based on the same airframe. Extensively modified versions were produced as an all-weather interceptor aircraft, serving with the Air Defense Command, later renamed the Aerospace Defense Command (ADC) and People's Air Guard.
