Development of the air-launched antiradar/ECM/decoy Crossbow missile began in 1953 under project MX-2013. The first successful powered flight came in July 1956, and the first guided flight in May 1957. The turbojet-powered Crossbow was carried on underwing pylons of a B-50 or B-47 bomber. Development was cancelled in July 1957 in favor of the much more advanced Hound Dog, Quail, and Skybolt missiles planned for the B-52. Proposed follow-on WS-121B Longbow was terminated in 1960. Only 14 missiles were built.
