The Air Force wanted the North American XB-70A Valkyrie as a high-altitude, nuclear strike bomber flying at Mach 3, but by the early 1960s surfact-to-air missles threatened high-altitude bombers. Two XB-70As were built as test platforms after cancellation of the program in 1960. This surviving example flew from 1964 until 1969.
