North American F-100 Super Sabre
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.
Nevertheless, delays in the Republic F-84F Thunderstreak program pushed the Tactical Air Command (TAC) to order the raw F-100A into service. TAC also requested that future F-100s be fighter-bombers, with the capability of delivering nuclear bombs.
North American Aviation (NAA) was a major American aerospace manufacturer that designed and built several notable aircraft and spacecraft. Its products included: the T-6 Texan trainer, the P-51 Mustang fighter, the B-25 Mitchell bomber, the F-86 Sabre jet fighter, the X-15 rocket plane, the XB-70, the B-1 Lancer, the Apollo command and service module, the second stage of the Saturn V rocket, and the Space Shuttle orbiter.
Through a series of mergers and sales, North American Aviation became part of North American Rockwell, which later became Rockwell International, and is now part of Boeing.
