## About This Content
A technological tour de force of epic proportions, the legend of the XB-70
Valkyrie™ very nearly surpasses the performance of this extraordinary
aircraft. Built in the 1960s as a result of a USAF proposal for a supersonic
bomber with high subsonic cruising speed and supersonic dash capabilities, the
massive XB-70™ was to have carried the same bombload as the B-52
Stratofortress™ at a higher supersonic speed than the Air Force’s current
strategic bomber, the B-58 Hustler™. A later requirement specified that the
plane be able to fly the entire mission at Mach 3.0 or greater, with a range
of up to 10,500 miles and a maximum gross weight of 490,000 pounds. In the
event, technology quickly relegated the Valkyrie to the role of supersonic
research testbed and flagship of the USAF’s public relations fleet. Ground-to-
air missiles and advanced radar made the XB-70’s supersonic mission
impossible. The bomb bay of the aircraft was instead packed with data
acquisition equipment.
