Fotografie amerického jaderného bombardéru + North American XB-70 Valkyrie

  • English: XB-70A parked on a ramp at Edwards Air Force Base in 1967.

Originally designed as a Mach 3 bomber, the XB-70A never went into production and instead was used for flight research involving the Air Force and NASA's Flight Research Center FRC, which was a predecessor of today's NASA Dryden Flight Research Center. The aircraft's shadow indicates its unusual planform. This featured two canards behind the cockpit, followed by a large, triangular delta wing. The outboard portions of the wing were hinged so they could be folded down for improved high-speed stability.
