The Mighty SeaMaster
Seamaster was the last aircraft built by Martin before ICBM’s became the wepon platform of choice for long range attacks. This Aircraft was designed during the Height of the SAC’s influence, intended to convoy with submarines and patrol boats to set up mobile bases with the idea that they would be hard to track. This aircraft made stunning first impressions; it was 50 feet longer than its predecessor, the P5M, and outweighed the massive
Mars by 25 tons! Its slender hull/fuselage and t-tail made it iconic, and instantly recognizable, along with a pronounced anhedral wing, used to rest pontoons on the water. Initially intended to use a Curtiss-Wright turbo-ramjet prototype for a ppowerplant, Martin instead used Allison J-71’s, which were lacking in power and due to their placement would scorch and damage the aft section of fuselage. Later, the P6M-2 used Pratt & Whitney J-75-T-2 engines, outputting 17,500 ft/lbs of thrust each, totaling 70,000 ft'lbs of gross thrust using four engines in pods of two, each pod exhaust now angled outboard 5 degrees. The original Seamasters beached with an external set of pontoons, which could deploy their own landing gear once attached. Taxiing tests on open waters revealed that the hull WAS indeed strong enough to endure six to nine-foot swells. First liftoff occurred on July 14th, 1955 over the Chesapeake Bay. The Seamaster was the first aircraft designed to maintain high speed at sea-level altitude. The bomb bay (not modeled) is sealed by air pressure, making it watertight. An initial order of 30 aircraft was placed, but supplying the aircraft with fuel and armament proved difficult, and soon the orders dwindled. Additionally, the rise of the ICBM meant that long-range nuclear attacks no longer required a separate carrier aircraft. This lead to the end of the contract, and Martin sought development in long-range missile technology, leaving aircraft design and engineering behind.
Action Groups: “1” toggles afterburner, “2” toggles flaps
Takeoff: Engage afterburner, Engage flaps. Wait until speed reaches 38 m/s, and then pull up.
Landing: Engage flaps, contact water at 60 m/s or less.
This is strictly a seaplane!
It is tricky to fly, for sure!
Built in the SPH in KSP version 1.2.2.
