The North American F-100 Super Sabre was a supersonic jet fighter aircraft that served with the United States Air Force (USAF) from 1954 to 1971 and with the Air National Guard (ANG) until 1979. The first of the Century Series collection of USAF jet fighters, it was the first USAF fighter capable of supersonic speed in level flight. The F-100 was originally designed by North American Aviation as a higher performance follow-on to the F-86 Sabre air superiority fighter.

Adapted as a fighter bomber, the F-100 would be supplanted by the Mach 2 class F-105 Thunderchief for strike missions over North Vietnam. The F-100 flew extensively over South Vietnam as the Air Force's primary close air support jet until replaced by the more efficient subsonic A-7 Corsair II. The F-100 also served in other NATO air forces and with other U.S. allies. In its later life, it was often referred to as "the Hun," a shortened version of "one hundred."

In January 1951, North American Aviation delivered an unsolicited proposal for a supersonic day fighter to the United States Air Force. Named Sabre 45 because of its 45° wing sweep, it represented an evolution of the F-86 Sabre. The mockup was inspected 7 July 1951 and after over a hundred modifications, the new aircraft was accepted as the F-100 on 30 November 1951. Extensive use of titanium throughout the aircraft was notable. On 3 January 1952, the USAF ordered two prototypes followed by 23 F-100As in February and an additional 250 F-100As in August.

Robert A. "Bob" Hoover (born January 24, 1922) is a former air show pilot and United States Air Force test pilot, known for his wide-brimmed straw hat and wide smile. In aviation circles, he is often referred to as "The pilots' pilot."

Bob Hoover learned to fly at Nashville's Berry Field while working at a local grocery store to pay for the flight training. He enlisted in the Tennessee National Guard and was sent for pilot training with the Army. During World War II, he was sent to Casablanca where his first major assignment was test flying the assembled aircraft ready for service. He was later assigned to the Spitfire-equipped 52nd Fighter Group in Sicily. In 1944, on his 59th mission, his malfunctioning Mark V Spitfire was shot down by a Focke-Wulf Fw 190 off the coast of Southern France and he was taken prisoner. He spent 16 months at the German prison camp Stalag Luft 1 in Barth, Germany.

He managed to escape from the prison camp, stole an Fw 190, and flew to safety in the Netherlands. After the war, he was assigned to flight-test duty at Wright Field. There he impressed and befriended Chuck Yeager. Later when Yeager was asked who he wanted for flight crew for the supersonic Bell X-1 flight, he named Bob Hoover. Hoover was Yeager's backup pilot in the Bell X-1 program and flew chase for Yeager in a Lockheed P-80 Shooting Star during the Mach 1 flight. He also flew chase for the 50th anniversary in an F-16 Fighting Falcon.
