The Jumo 211 engine was designed by a team led by professor Hugo Junkers, an excellent aircraft and engine designer. Its development was connected with the plans of rapid extension of German military aviation. Several versions of the engine were built in large numbers throughout World War II. Production totalled about 68,OOO examples. The Jumo 211 powered most variants of the Heinkel He 111 and Junkers Ju 88 bombers, and the Junkers Ju 87 dive bombers.
