The Daimler-Benz DB 605 is a German aircraft engine, built during World War II. Developed from the DB 601, the DB 605 was used from 1942 to 1945 in the Messerschmitt Bf 109 fighter, and the Bf 110 and Me 210C heavy fighters. The DB 610, a coupled "power system" powerplant comprising a pair of side-by-side configured examples of the DB 605, geared together in the front to turn a single output shaft, was used in Germany's only operational heavy bomber, the Heinkel He 177.
License-built versions of the DB 605 were used in the Macchi C.205, Fiat G.55, Reggiane 2005 and some other Italian aircraft. It was also initially used in the pusher-design Swedish Saab J21. Approximately 42,400 DB 605s of all kinds were built.
