The Heinkel He.111 was a German monoplane medium bomber (also torpedo bomber and attack bomber). The Hе.111 H-3 entered production in November 1939 and could also be used in a naval bomber role. However its defensive armament was not particularly effective, with limited defensive arcs and a very low rate of fire of only 540 rounds per minute.
The He.111 H-3 had a crew of five, but when used in a maritime role, this would usually be increased to six. The bomber was powered by Jumo 211 D-1 engines with a takeoff power of 1,200 HP. Up to 2,000 kg of bombs could be housed in the bomb bay; the left section of the bay could also house extra fuel tanks.
