Cockpit view of the Messerschmitt Bf 109G-10 in the National Museum of the U.S. Air Force World War II Gallery. The Messerschmitt Bf 109 began as an entry by the Bayerische Flugzeugwerke in a Luftwaffe (German Air Force) fighter competition in the early 1930s. Willy Messerschmitt's creation incorporated one of the most advanced aerodynamic designs at the time, with retractable landing gear, an enclosed cockpit, automatic slats, cantilever wings and stressed skin construction. During the trials, the Bf 109 clearly outperformed the larger and heavier favorite, Heinkel's He 112. The first production model, the Bf 109B, began coming off the lines in 1936.
