The Northrop BT was a two seat, single engine, monoplane, dive bomber built by the Northrop Corporation for the US Navy. At the time Northrop was a subsidiary of the Douglas Aircraft Company. The design of the initial version began in 1935. A 700 hp Pratt and Whitney XR-1535-66 Twin Wasp Jr. double row, radial air-cooled engine powered the aircraft. The aircraft had slotted flaps and a landing gear that partially retracted.
The next iteration of the BT, designated the XBT-1 was equipped with a 750 hp R-1535 engine. This aircraft was followed in 1936 by the BT-1 that was powered by an 825 hp Pratt and Whitney R-1535-94 engine. One of the BT-1 aircraft was modified with a fixed tricycle landing gear and was the first such aircraft to land on an aircraft carrier.
The next version, the XBT-2, was a BT-1 aircraft modified to incorporate a fully retracting landing gear, wing slots, a re-designed canopy, and was powered by an 800 hp Wright XR-1820-32 radial air-cooled engine. The XBT-2 first flew on 25 April 1938 and became the prototype for the Douglas SBD-1.
