The incomplete XB-70 Valkyrie was designed to become a US B-70 nuclear-capable strategic bomber. The prototype for the plane was able to reach an acceleration of 2,056 miles per hour. The plan for the jet was abandoned when the Soviet Union introduced a new missile defense system.
Following the closure of the B-70 Program, two prototypes were kept and used as test vehicles for high-speed flights. The XB-70 Valkyrie experienced its only time in flight in 1964.
