Martin T3M

The Martin T3M was an American single-engined three-seat torpedo bomber biplane of the 1920s that became a standard torpedo bomber of the United States Navy, operating from land bases and aircraft carriers from 1926 to 1932. Having built 75 Martin SC aircraft, the production version of the Curtiss CS, the Glenn L. Martin Company offered an improved design in answer to a Navy requirement, and the T3M-1 first flew in July 1926. It could have wheels or floats, had a welded steel tube fuselage, and used a 575 horsepower Wright T-3B V-12 engine in 24 T3M-1 aircraft. The underpowered T3M-1 gave way to the T3M-2, with a 770 horsepower Packard engine and revised wings, of which the Navy ordered 100.
