The North American F-100 Super Sabre was 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.
