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 it was determined to be too ambitious a project given technical difficulties with the SM-62 Snark which it was to follow on from and was canceled in 1951.
