The Martin P6M SeaMaster built by the Glenn L. Martin Company was a 1950s strategic bomber flying boat for the United States Navy that almost entered service; production aircraft had been built and Navy crews were undergoing operational conversion with a service entry about six months off when the program was cancelled on August 21 1959. Envisioned as a way to give the Navy a strategic nuclear force the SeaMaster was eclipsed by the Polaris submarine launched ballistic missile.
