Commonly known as the 'Gustav' because of the G suffix in its name, The Messerschmitt Bf 109G began rolling off assembly lines in February 1942 and remained in production until the end of World War II. The Bf 109G was mainly distinguished from its predecessor by the fact that it incorporated the Daimler Benz DB 605 A engine, a powerplant with a take off rating of 1,475 h.p. - 125 h.p. more than the DB 601E engine in the Bf 109F-4. Production of the Bf 109G was also undertaken by Germany's Allies, including Romania and Hungary. No reliable manufacturing statistics survive but it is estimated that a massive 23,000 Gustavs were built by the end of the war.
