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 — and which, like the similar DB 606 that it replaced, weighed 1,515 kg — was used in the A-3 and all A-5 variants of Germany's only operational heavy bomber, the Heinkel He 177A.
