The North American F-100 Super Sabre is an American 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 of USAF jet fighters, it was the first USAF fighter capable of supersonic speed in level flight. The F-100 was 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 was supplanted by the Mach two-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 being replaced by the more efficient subsonic LTV 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".

Variants

YF-100A - Prototype, model NA-180 two built, s/n 52-5754 and 5755.

YQF-100 - Nine test unmanned drone versions

F-100A- Single-seat day fighter; 203 built, model NA-192.

RF-100A ("Slick Chick") - Six F-100A aircraft modified for photo reconnaissance in 1954. Unarmed, with camera installations in lower fuselage bay. Used for overflights of Soviet Bloc countries in Europe and the Far-East. Retired from USAF service in 1958, the surviving four aircraft were transferred to the Republic of China Air Force and retired in 1960.

F-100B - See North American F-107

F-100BI - Proposed interceptor version of F-100B, did not advance beyond mock-up.

F-100C - Seventy Model NA-214 and 381 Model NA-217. Additional fuel tanks in the wings, fighter-bomber capability, probe-and-drogue refueling capability, uprated J57-P-21 engine on late production aircraft. First flight: March 1954; 476 built.

TF-100C - One F-100C converted into a two-seat training aircraft.
