Full Documentary, A Look at the Bell X-2, North American XB-70 Valkyrie, Mikoyan-Gurevich Mig-25, McDonnell Douglas F-15 Eagle, Concorde, Lockheed F-104 Starfighter, Bell X-1, and Chuck Yeager's biography. as well as a look at Skunk Works Kelly Johnson, or the X-15, SR-71, YF-12, X-43A and X-51 and the history of the American SST program, and the Boeing 2707. The North American Aviation XB-70 Valkyrie was the prototype version of the planned B-70 nuclear-armed, deep-penetration supersonic strategic bomber for the United States Air Force Strategic Air Command. Designed in the late 1950s by North American Aviation (NAA), the six-engined Valkyrie could cruise for thousands of miles at Mach 3+ while flying at 70,000 feet (21,000 m). By the mid-1950s, the United States had developed a state-of-the-art, all-jet-powered bomber force. The newly introduced Boeing B-52 Stratofortesss could reach the Soviet Union from just about anywhere in the world. The soon-to-be-introduced supersonic Convair B-58 Hustler could dash to supersonic speeds. Both aircraft were engineering marvels. But even so, they were expected to perform poorly over Soviet airspace. The B-52 flew too slowly to stand a chance against the latest generation of Soviet interceptors, while the supersonic B-58 lacked the required range and payload to be truly effective. The U.S. Air Force needed a next-generation bomber that would combine the capabilities of both these aircraft. A plane that could fly at supersonic speeds travel long distances and carry large payloads. To meet their new bomber requirements, the Air Force contracted leading aerospace companies to explore radical new technologies, like nuclear-powered jet engines for extending aircraft range and high-energy ‘zip-fuels’ to increase aircraft performance. Boeing and North American Aviation would play a vital role in research. But given the limitations of technology, the most practical solution was the ‘dash concept’, which detailed an enormous aircraft that would travel most of the way to its target subsonically before jettisoning outer portions of its wings and fuel tanks to make a supersonic dash. These concepts were studied in an era of extraordinary advances in aviation technology and engineering, and by 1957 it became apparent that it might be possible to build a large, long-range bomber that could fly supersonically over its entire mission. In 1957, the Air Force outlined their specifications for an aircraft that would cruise at Mach 3, up to an altitude of 75,000 feet. It was expected to offer a similar payload and range to the B-52. Boeing and North American Aviation submitted design concepts, but North American’s proposal was selected for development. A key principle in North America’s design was compression lift, which would significantly improve the aircraft’s lift-to-drag ratio when flying at high supersonic speeds. The new bomber would be designed as the B-70 (XB-70 in experimental prototype form) and named the Valkyrie.
