Me-109

The Messerschmitt Bf 109 was a German World War II fighter aircraft designed by Willy Messerschmitt in the early 1930s. It was one of the first true modern fighters of the era, including such features as an all-metal monocoque construction, a closed canopy, and retractable landing gear. The Bf 109 was produced in greater quantities than any other fighter aircraft in history, with a total of 33,984 units produced up to April 1945.

The Bf 109 was the backbone of the Luftwaffe fighter force in World War II, although it began to be partially replaced by the Focke-Wulf Fw 190 from 1941. The Bf 109 was the most successful fighter of World War II, shooting down more aircraft than any of its contemporaries. Originally conceived as an interceptor, it was later developed to fulfill multiple tasks, serving as bomber escort, fighter bomber, day-, night- all-weather fighter, bomber destroyer, ground-attack aircraft, and as reconnaissance aircraft. Although the Bf 109 had weaknesses, including short range and challenging take off and landing characteristics, it stayed competitive with Allied fighter aircraft until the end of the war.
