The XB-70A Valkyrie is one of the sleekest, good-looking military aircraft ever built. Unfortunately, the aircraft appeared just at a time when military requirements were changing and the manned bomber was being de-emphasized in favor of intercontinental ballistic missiles. The XB-70A program came out from the Boeing Aircraft Corporation's MX-2145 Project after Boeing along with the Band Corporation conducted studies relating to the type of weapon system required to deliver high-yield special weapons. The study included intercontinental bombers, delivering both gravity bombs and pilot-less parasite bombers; manned bombers, air-refueled by tankers to attend their ranges and cover round-trip intercontinental distances; manned aircraft and drone bomber combinations; and unmanned bombers. During the study, the Air Force requested to further include possible trade-off information on weight for speed, weight for range and speed for range. Boeing managed to present the requested information on 22 January 1954, pointing out the possibilities of a bomber aircraft powered by chemically augmented nuclear power plants. It was B-70. In May 1946, the Army Air Forces signed a treaty with the Fairchild Engine and Airplane Corporation, conferring on the highly classified. With regard to operational characteristics, the new weapon system was to rely primarily on nuclear weapons to accomplish its mission, and the origin and termination of its operations were to be within the limits of the North American continent. The Air Force specified that weapon system I l0A/L would have to be capable of performing during the day, at night, and in any kind of weather. A minimum unrefueled radius of 4,000 nautical miles, and a desirable extended radius of 5,500 nautical miles were required, with aerial refueling allowed in the latter case. Finally, the minimum target altitude was to be 60,000 feet, and the contracts reiterated that cruise speed could not be less than mach .9, with maximum supersonic dash speed in the combat zone. These were exacting characteristics. Studies of conventional aircraft had shown that no such performance could be obtained with proven design techniques. The Air Force acknowledged that the ability to satisfy its demands, particularly the radius-of-action and speed requirements, would depend on the use of high-energy fuels, new engines, new design techniques, and some other break-through in the state-of-the-art by the operational date of 1963. The Air Force also made sure that the contractors knew that while range and speed trade-offs would be acceptable in order to assure maximum supersonic dash at a "practical" gross weight, every reduction would have to be minimal. Finally, the new weapon system's configuration would have to allow for the easy addition of state-of-the-art improved subsystems and components, not initially incorporated.
