TX-29

Early in 1954, a feasibility study of the warhead was authorized for use with the NAVAHO, a supersonic, surface-to-surface, pilotless bomber (as the missiles were called in those days), capable of striking targets at ranges up to 3500 nautical miles. Initial studies showed that it would be difficult to provide a warhead with the desired weight, and the program was temporarily set aside pending receipt of data from Operation Teapot. Subsequently, the Division of Military Application notified the Military Liaison Committee March 16, 1955, that it appeared better to proceed with modifications to the Mk 15 program, which would provide a lighter caseand a contact fuze, than to continue with work on the TX-29. It was pointed out that a completely new design, such as the TX-29, might providea slightly increased yield over the Mk 15 design. The program was subsequently canceled by the Division of Military Application August 25, 1955.
