- Xb 70 valkyrie speed. To achieve Mach 3 performance, the B-70 was XB-70 Valkyrie With a top speed of Mach 3 and a cruising altitude of more than 70,000 feet, the XB-70 was designed to be too fast and too high for any Soviet aircraft to Early on, however, there were plans to follow the B-58 with a much more capable supersonic bomber, the "B-70 Valkyrie", but only two XB-70 prototypes were XB-70A-1-NA 62-0001 rollout at Air Force Plant 42, 11 May 1964. Its inaugural flight — 60 years ago in September 1964 — kicked The XB-70 Valkyrie, with a planned cruise speed of Mach 3 and operating altitude of 70,000 feet, was to be the ultimate high-altitude, high-speed manned The XB-70’s use of exotic materials and its sophisticated cooling systems provided valuable data for future high-speed aircraft—including the The XB-70 Valkyrie was a supersonic bomber aircraft designed to fly at over three times the speed of sound while carrying nuclear weapons. The XB-70 Valkyrie was primarily designed as a high-altitude, supersonic strategic bomber and was not specifically developed to carry This is the story of the Valkyrie XB70 nuclear strike When Strategic Air Command drew up its B-70 plans a half-century ago, the Valkyrie was projected to become the centerpiece of the most advanced fleet of manned The North American XB-70 Valkyrie, an experimental military aircraft, reached a top speed of up to Let's take a look at what was to be the ultimate high The B-70 Valkyrie, with a planned cruise speed of Mach 3 and operating altitude of 70,000 feet, was to be the ultimate high-altitude, high-speed manned strategic bomber.
