Model Name:   XB-70 VALKYRIE

History:
The North American Aviation XB-70 Valkyrie was the prototype version of the proposed B-70 nuclear-armed deep penetration bomber for the United States Air Force's Strategic Air Command. Designed in the late 1950s, the Valkyrie was a large six-engined aircraft able to fly Mach 3+ at an altitude of 70,000 ft (21,000 m), which would have allowed it to avoid interceptors, the only effective anti-bomber weapon at the time.

The introduction of effective high-altitude surface-to-air missiles, the program's high development costs, and changes in the technological environment with the introduction of ICBMs led to the cancellation of the B-70 program in 1961. Although the proposed fleet of operational B-70 bombers was cancelled, two prototype aircraft were built as the XB-70A and used in supersonic test flights from 1964 to 1969. One prototype crashed following a midair collision in 1966; the other is on display at the National Museum of the United States Air Force in Ohio.
