Photos - One more bird from the shops of Martin Aircraft. This a Martin XP6M-1 Seamaster, which first flew on 14 July 1955. It was a swept-wing seaplane powered by four Allison J-71 tubojet engines, and would have been tasked with the delivery of nuclear weapons and the laying mines. Unfortunately, it did not survive its four years of operational evaluation, and was eventually cancelled. This was the last in the long line of Martin flying boats I really wish I could have seen one of these in action. Fly Navy

 

The Martin P6M SeaMaster was an experimental strategic bomber flying boat built by the Glenn L. Martin Company for the United States Navy that almost entered service; production aircraft were built and Navy crews were undergoing operational training, with service entry expected in about six months, when the program was cancelled on 21 August 1959. Envisioned as a strategic nuclear weapon delivery system for the Navy, the SeaMaster was eclipsed by the Polaris submarine-launched ballistic missile (SLBM). Due to the political situation at the Pentagon, the Navy promoted the P6M primarily as a high speed minelayer.
