Daimler-Benz DB 602
The Daimler-Benz DB 602, originally known as Daimler-Benz LOF.6, was a German diesel cycle aero 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 Schnellboot-type attack craft of 1933 series S10...13. The engine was modified into V20 MB 501 of 2000 hp that had a variety of applications.
