Daimler-Benz DB 603
The Daimler-Benz DB 603 was a German aircraft engine used during World War II. It was a liquid-cooled 12-cylinder inverted V12 enlargement of the 33.9 Liter DB 601, which was in itself a development of the DB 600. Production of the DB 603 commenced in May 1942, and with a 44.5 liter (44,500 cc) displacement, was the largest displacement inverted V12 aircraft engine to be used in front line aircraft of the Third Reich during World War II. The DB 603 powered several aircraft, including the Do 217 N&M, Do 335, He 219, Me 410, BV 155 and Ta 152C. == Design and development == As Germany's largest displacement inverted V12 aviation powerplant in production during the war years, the DB 603 saw wide operational use as the primary engine type for many twin and multi-engined combat aircraft designs — the promising twin-engined Dornier Do 335 Pfeil prototype heavy fighter, the front-line Messerschmitt Me 410 Hornisse heavy fighter and Heinkel He 219 Uhu twin-engined night fighter were all designed to be powered by the DB 603.
