The Fastest Nuclear Bomber That Looked Fake
The XB-70 Valkyrie was a supersonic strategic bomber developed by the United States in the 1950s and 1960s by North American Aviation for the U.S. Air Force. The aircraft was designed to be capable of flying at Mach 3 (three times the speed of sound) at high altitudes, allowing it to outrun interceptors and surface-to-air missiles.
