re carriers etc - same funding discussion re what USAF, USN and USMC have from a deterent perspective.
the original great planes documentary, not the trashy discover remake gives a good overview of the projects going on publically and not publically and how the infighting panned out.
the seamaster was cancelled really before it flew....... really keeping martin in business
really interesting to compare the US approach with that of UK
see wiki " The major defense budget cuts of the Eisenhower administration were forcing the Navy to make choices. In August 1959 Martin was told to halt operations; the program was going to be canceled. Seaplanes were a small community in Naval Aviation, and the P6M, significantly over budget and behind schedule, was competing with aircraft carriers for funding. The Navy had an impending superior system for the nuclear strike role, the Fleet Ballistic Missile Submarine." ref
