TheDouglas DTbomber was theDouglas Aircraft Company's first military contract, forging a link between the company and theUnited States Navy. Navy Contract No. 53305 of April 1, 1921, required only 18 pages to set out the specifications that resulted in the purchase of three DT (D for Douglas, T fortorpedo) folding-wingaircraft.

The DT used a welded steel fuselage with aluminum covering the forward and center sections and fabric covering the rear section. Douglas built 46 DT-1 and DT-2 torpedo bombers for the U.S. Navy, Norwegian Navy, andPeruvian Navy. 20 DT-2 aircraft were built under license by theL-W-F Engineering Company Inc., six by theNaval Aircraft Factory (NAF), and 11 by theDayton-Wright Company. Another seven were built forNorway under license byMarinens Flyvebåtfabrik. Although still in servicewhen the Germans invaded Norway, the Norwegian DTs did not see action in theNorwegian Campaign. The DT could be fitted either with pontoons or wheeledlanding gear and could carry a 1,800 lb (816 kg) torpedo.

The first flight was in November1921 and production continued until1929. The DT operated off the U.S. Navy's first aircraft carrier,USS Langley, from land bases, and fromseaplane tenders. Several were flown by theMarine Corps.

Variations of the DT-2 aircraft were designated DT-4, DT-5, DT-6, and DTB. Machines licence-built byDayton-Wright were internally designatedSDW by that company. The type became the basis for theDouglas World Cruiser.
