The X-10 Was Built to Smash Russia in a Nuclear War
North American built 13 X-10s, ten of which were used in test flights, with the first of those occurred in October 1953. They had one mission.
During the early days of the Cold War, the U.S. military sought new ways of delivering a nuclear warhead to a target. One platform to do that, the Navaho surface-to-surface cruise missile, utilized the North American Aviation (NAA) RTV-A-5 (Research Test Vehicle, Air Force). Also known as the X-10, the turbojet-powered aircraft was used to test the flight characteristics and guidance, navigation, and control systems for the planned SM-64 Navaho.
