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 figure, was the largest displacement inverted V12 aviation engine to be produced and used in front line aircraft of the Third Reich during World War II.
