On 20 June 1941, the United States Navy placed an order with the Douglas Aircraft Company for two prototypes of a new two-seat dive bomber to replace both the Douglas SBD Dauntless and the new Curtiss SB2C Helldiver, designated XSB2D-1. The resulting aircraft, designed by a team led by Ed Heinemann, was a large single-engined mid-winged monoplane. It had a laminar flow gull-wing, and unusually for a carrier-based aircraft of the time, a tricycle undercarriage. It was fitted with a bomb bay and underwing racks for up to 4,200 lb (1,900 kg) of bombs or one torpedo (typically the Mark 13), while defensive armament consisted of two wing-mounted 20 mm (0.79 in) cannon and two remote-controlled turrets, each with two .50 in (12.7 mm) machine guns
The prototype first flew on 8 April 1943, demonstrating good performance, being faster than the Dauntless and capable of carrying more bombload, but it was heavier and more complex. The U.S. Navy had made a request for a new torpedo bomber developed from the XSB2D-1. Douglas reworked the XSB2D-1 by removing the turrets and second crewman, while adding more fuel and armor, while wing racks could carry not just one but two torpedoes, producing the BTD-1 Destroyer. The orders for the SB2D-1 were converted to the BTD-1, with the first BTD-1 flying on 5 March 1944. The BTD-1 was heavier than the XS2BD-1 and had poorer performance. Ed Heinemann asked for cancelling of the BTD-1.
