The
Messerschmitt Bf 109, commonly called the
Me 109 (most often by
Allied aircrew and even amongst the German aces themselves, even though this was not the official German designation), is a
German World War II fighter aircraftdesigned by
Willy Messerschmitt and
Robert Lusser during the early to mid-1930s. The "Bf 109" designation was issued by the German ministry of aviation and represents the developing company
Bayerische Flugzeugwerke (at which the engineer Messerschmitt led the development of the plane) and a rather arbitrary figure. It was one of the first truly modern fighters of the era, including such features as all-metal
monocoque construction, a closed
canopy, and retractable
landing gear. It was powered by a
liquid-cooled, inverted-
V12 aero engine.
The Bf 109 first saw operational service during the
Spanish Civil War and was still in service at the dawn of the jet age at the end of World War II, during which time it was the backbone of the
Luftwaffe's fighter force. From the end of 1941, the Bf 109 was steadily being supplemented by the superior
Focke-Wulf Fw 190.
Originally conceived as an
interceptor, later models were developed to fulfill multiple tasks, serving as
bomber escort,
fighter-bomber,
day-,
night-, all-weather fighter,
ground-attack aircraft, and as
reconnaissance aircraft. It was supplied to and operated by several states during World War II, and served with several countries for many years after the war. The Bf 109 was the most produced fighter aircraft in history, with a total of 33,984 airframes produced from 1936 up to April 1945.
The Bf 109 was flown by the three top-scoring German
fighter aces of World War II, who claimed 928 victories among them while flying with
Jagdgeschwader 52, mainly on the
Eastern Front. The highest scoring fighter ace of all time,
Erich Hartmannof Germany, flew the Bf 109 and was credited with 352 victories (and also survived the war). The plane was also flown by
Hans-Joachim Marseille, the highest scoring German ace in the
North African Campaign, who scored 158 victories - 154 of which were against
fighter aircraft flown by western-trained pilots. It was also flown by several other aces from
Germany's allies, notably
Finn Ilmari Juutilainen, the highest scoring non-German ace on the type
with 58 victories flying the Bf 109G, and pilots from
Italy,
Romania,
Croatia,
Bulgaria and
Hungary. Through constant development, the Bf 109 remained competitive with the latest
Allied fighter aircraft until the end of the war.
