The North American F-100 Super Sabre was a 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. As the first of the Century Series collection of USAF jet fighters, it was the first of a series of US fighters capable of supersonic speed in level flight and made extensive use of titanium throughout the aircraft.
The F-100 was designed originally as a higher performance follow-on to the F-86 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 several NATO air forces and with other US allies. In its later life, it was often referred to as "the Hun," a shortened version of "one hundred."
