A single-engined three-seat biplane, it became a standard torpedo bomber of the U.S. Navy, operating from both land bases and from aircraft carriers from 1926 to 1932.

[1] The T3M was a large single-engined biplane capable of being fitted with either a conventional tailwheel undercarriage or floats.

The fuselage was constructed of welded steel tube in place of the riveted steel frame of the CS/SC,[2] with the pilot and bombardier seated side by side in the front cockpit situated forward of the wing, with the bombardier having a position under the nose for aiming the aircraft's bombs or torpedoes, while the gunner had a cockpit well aft of the wing, with a radiator slung under the top wing between the cockpits.

[4] The U.S. Navy ordered 100 T3M-2s, one of which was re-engined with the Pratt & Whitney Hornet and the Wright Cyclone radial engines as the XT3M-3 and XT3M-4 respectively.
