The sleek Valkyrie took advantage of "compression lift," where the shock wave generated by the airframe at supersonic speed supports part of the airplane's weight. The XB-70A could also droop its wingtips as much as 65 degrees for additional stability at high speeds. (U.S. Air Force photo)

The Valkyrie’s airframe was built with advanced techniques and materials to reduce weight and to withstand high temperatures from aerodynamic heating at high speed. (U.S. Air Force photo)

The futuristic XB-70A was originally conceived in the 1950s as a high-altitude, nuclear strike bomber that could fly at Mach 3 (three times the speed of sound) -- any potential enemy would have been unable to defend against such a bomber.

By the early 1960s, however, new Surface-to-Air Missiles (SAMs) threatened the survivability of high-speed, high-altitude bombers. Less costly, nuclear-armed ICBMs (Intercontinental Ballistic Missiles) were also entering service. As a result, in 1961, the expensive B-70 bomber program was canceled before any Valkyries had been completed or flown.

Even so, the USAF bought two XB-70As to test aerodynamics, propulsion and other characteristics of large supersonic aircraft. The first XB-70A, on display here, flew in September 1964, and it achieved Mach 3 flight in October 1965. The second Valkyrie first flew in July 1965, but in June 1966, it was destroyed following an accidental mid-air collision. The third Valkyrie was not completed.

The first XB-70A airplane continued to fly and generate valuable test data in the research program until it came to the museum in 1969.
