The British Aircraft Corporation TSR-2 was a cancelled Cold War strike and reconnaissance aircraft developed by the British Aircraft Corporation (BAC) for the Royal Air Force (RAF) in the late 1950s and early 1960s. The TSR-2 was designed to penetrate a well-defended forward battle area at low altitudes and very high speeds, and then attack high-value targets in the rear with nuclear or conventional weapons. Another intended combat role was to provide high-altitude, high-speed photo reconnaissance. Some of the most advanced aviation technology of the period was incorporated in order to make it the highest-performing aircraft in the world in its projected missions. Only one airframe flew and test flights and weight rise during design indicated that the aircraft would be unable to meet its o
