The XSSM-A-5 Boojum, also known by the project number MX-775B, was a supersonic cruise missile developed by the Northrop Corporation for the United States Air Force in the late 1940s. Intended to deliver a nuclear warhead over intercontinental range, the project was determined to be too ambitious given technical difficulties with the SM-62 Snark which it was planned to follow, and it was canceled in 1951.
