The Kh-15 was a missile carried by the supersonic strike bomber operated by what organization?
Tupolev Tu-22M The Tupolev Tu-22M (Russian: Туполев Ту-22М; NATO reporting name: Backfire) is a supersonic, variable-sweep wing, long-range strategic and maritime strike bomber developed by the Tupolev Design Bureau. According to some sources, the bomber was believed to be designated Tu-26 at one time. During the Cold War, the Tu-22M was operated by the Soviet Air Force (VVS) in a strategic bombing role, and by the Soviet Naval Aviation ("Aviacija Vojenno-Morskogo Flota", AVMF) in a long-range maritime anti-shipping role. Significant numbers remain in service with the Russian Air Force, and as of 2014 more than 100 Tu-22Ms are in use.
North American X-15 The North American X-15 was a hypersonic rocket-powered aircraft operated by the United States Air Force and the National Aeronautics and Space Administration as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's official world record for the highest speed ever recorded by a manned, powered aircraft, set in October 1967 when William J. Knight flew Mach 6.72 at 102100 ft , a speed of 4520 mph (2020.278 meters per second), has remained unchallenged as of .
