Provenance Model of the NAC-60, which was North American Aviation's SST airframe concept, with a delta-wing design of 195 feet long that would carry 187 passengers. Maximum cruising speed was to be Mach 2.65 (1750 mph) with a cruising altitude of 35,000 feet.

North American's SST design was based on the XB-70 prototype of its proposed B-70 Valkyrie high-altitude, high-speed bomber, which had a delta wing housing six engines, hinged outer wings, and a planned cruise speed of Mach 3 and operating altitude of 70,000 feet. North American's proposed SST had a less tapered fuselage than the XB-70, and new compound delta wing, but retained the XB-70's high-mounted canard and box-like engine area under the fuselage.

Unique to the North American's NAC-60 nose, was that only the windscreen adjusted for supersonic flight, avoiding the complexity and weight of the droop nose adopted by Boeing and Lockheed for their proposed SST designs.

Of the SST airframes presented by Boeing, Lockheed and North American, the NAC-60 was the first to be eliminated from the competition in 1966. Boeing was eventually awarded a contract for two SST prototypes in May 1967.
