The Messerschmitt Bf 109 was a German World War II fighter aircraft that was used by the Luftwaffe, the air force of Nazi Germany, from 1935 until the end of the war in 1945. It was designed by Willy Messerschmitt and Robert Lusser during the early 1930s, and was the most produced fighter aircraft in history, with over 30,000 produced.
The Bf 109 was a cantilever low-wing monoplane with a closed cockpit and a retractable tailwheel landing gear. It was powered by a single Junkers Jumo 211 or Daimler-Benz DB 601 engine, and was armed with two MG 17 machine guns and two MG FF cannons.
The Bf 109 was a very successful fighter aircraft, and was used in all theaters of World War II. It was particularly effective in the early years of the war, when it was flown by some of the most experienced and skilled German pilots. However, as the war progressed, the Bf 109 was gradually outclassed by newer Allied fighter aircraft, such as the Supermarine Spitfire and the North American P-51 Mustang.
The Bf 109 remained in service with the Luftwaffe until the end of the war, and was also used by a number of other countries after the war. It was a very influential design, and its success led to the development of a number of other successful fighter aircraft, including the Messerschmitt Me 262 and the Focke-Wulf Fw 190.
The top speed of the Bf 109 varied depending on the model and engine, but the top speed of the Bf 109 G-10/U4, which was the most powerful and most advanced variant of the Bf 109, was 469 mph. This made the Bf 109 one of the fastest fighter aircraft of World War II.
