The Heinkel He 45 was a light bomber produced in Germany in the early 1930s, one of the first aircraft adopted by the newly formed ''Luftwaffe''. Its appearance was that of a conventional biplane and included seating for pilot and gunner in tandem, open cockpits. Developed in parallel with the He 46, it appeared in 1931 as a general-purpose biplane and was employed mainly as a trainer, but was also used by the ''Luftwaffe'' for reconnaissance and light bombing duties. Production of this plane totalled 512 aircraft, including those built under licence by Gotha, Focke-Wulf, and BFW.
