The Heinkel He 111 was a German aircraft designed by Siegfried and Walter Günter in the early 1930s to provide the Luftwaffe with a fast medium bomber.
Perhaps the best-recognized German bomber due to the distinctive "greenhouse" nose of later versions, the Heinkel was the Luftwaffe's primary and most numerous bomber during the early stages of World War II. It fared well until the Battle of Britain, when its weak defensive armament, relatively low speed, and poor maneuverability were exposed. Nevertheless, it proved capable of sustaining heavy damage and remaining airborne. As the war progressed, the He 111 was used in a variety of roles on every front in the European Theatre. It was used as a strategic bomber during the Battle of Britain, a torpedo bomber during the Battle of the Atlantic, and as a medium bomber and a transport aircraft on the Western, Eastern, and Mediterranean Fronts.
