The P6M Seamaster, built by the Martin Co., was a jet powered flying boat that underwent trials for the United States Navy. It was intended to be a strategic bomber, capable of dropping nuclear ordnance. However, at the time of its trials, the Navy said that the aircraft was to be used primarily as a patrol flying boat and for mine laying.

A total of twelve P6M Seamaster prototype aircraft were produced. Initially under powered, the aircraft were able to fly at trans-sonic speeds when fitted with more powerful engines. They were the fastest, highest flying, four engine flying boats ever made.

Initially handling problems were encountered, but these were overcome. However, after almost ten years of testing, the project was over budget and schedule. Shortly before P6M production was about to begin, the Navy decided on a different strategic weapons delivery system.

Nuclear powered submarines were being built with the ability to launch long range missiles. The P6M Seamaster could not justify its cost as a patrol flying boat or mine layer. No production aircraft were ever built.
