The He 111F saw the first major change to the basic design of the aircraft. In order to simplify production the elliptical wing used in all earlier models was replaced by a more traditional straight edged wing. As a result the wingspan of the aircraft was reduced from 74 feet 1.8 inches to 73 feet 9.8 inches. The new wing had first been used on the He 111G commercial transport version of the aircraft, but was not introduced into military production until late in 1937.
The pre-production F-0 was completed late in 1937. It was powered by the 1,100hp Junkers Jumo 211A-3 engine, giving it a top speed of 267mph at 16,400 feet.
Twenty-five He 111F-1s were built for Turkey during 1938, remaining in service in Turkey until 1946.
The F-2 was similar to the F-1 but with improved radio equipment. Twenty were built.
The F-3 was a reconnaissance version that was never built.
The F-4 was similar to the E-4, with external bomb racks. Forty were built during 1938, before the He 111F was replaced by the He 111P with its improved nose.
