The Daimler-Benz DB 602 was a Germandiesel cycleaero engine designed and built in the early 1930s. It was a liquid-cooled upright V16, and powered the two Hindenburg class airships. It has roughly the same displacement and weight of the Beardmore Tornado, which was used in the ill-fated R101, but has almost twice the power of the Tornado, showing Daimler-Benz's superior knowledge regarding diesel engine construction. Also, these engines, under designation MB 502, powered four Schnellboots of 1933 series S10...13 (three engines on each). Then, the engine was modified into V20 MB 501 of 2000 hp that had a variety of applications.
