The Messerschmitt Bf 109 (often incorrectly called the Me 109) was the standard fighter aircraft of the German Luftwaffe throughout World War II. It was one of the first truly modern fighters, featuring all-metal monocoque construction, a closed canopy, retractable landing gear, and was powered by a liquid-cooled inverted-V12 engine. First flown in 1935, it was the most produced fighter aircraft in history with over 33,000 airframes produced from 1936 to April 1945.
Design and Development
The Bf 109 was designed by Willy Messerschmitt and Robert Lusser during the early 1930s. It first flew on 28 May 1935 powered by a Rolls-Royce Kestrel engine, as the intended Junkers Jumo 210 was not yet available. The design won the 1935 Reichsluftfahrtministerium fighter competition against the Arado Ar 80, Focke-Wulf Fw 159, and Heinkel He 112.
Messerschmitt used the smallest possible airframe combined with the most powerful available engine. The result was a small, fast, and agile fighter, though the narrow-track undercarriage led to many landing accidents throughout the type's service life.
Operational History
The Bf 109 saw its combat debut during the Spanish Civil War (1936–1939) with the Condor Legion, where early models proved superior to Republican fighters. By the outbreak of World War II, the Bf 109E (Emil) was the Luftwaffe's primary fighter.
During the Battle of Britain (1940), the Bf 109E proved roughly equal to the Supermarine Spitfire Mk I, though its limited range meant it could only spend about 20 minutes over England when flying from bases in France. The Bf 109F (Friedrich), introduced in 1941, is considered by many to be the best-handling variant of the series.
The Bf 109G (Gustav), introduced in 1942, was the most-produced variant. While faster and more heavily armed than earlier models, the additional weight degraded handling qualities somewhat. The final major variant, the Bf 109K (Kurfurst), entered service in late 1944.

Notable Aces
The Bf 109 was flown by the highest-scoring fighter aces in history, including Erich Hartmann (352 victories), Gerhard Barkhorn (301), and Gunther Rall (275). All three flew Bf 109G variants on the Eastern Front.
Legacy
After the war, Bf 109 production continued in Czechoslovakia (as the Avia S-199) and Spain (as the Hispano Aviacion HA-1112 Buchon). The Spanish aircraft, re-engined with Rolls-Royce Merlin engines, served until the 1960s and were later used in the 1969 film Battle of Britain.
