Messerschmitt Bf 109
The Messerschmitt Bf 109, was a German World War II fighter aircraft that was the backbone of the Luftwaffe‘s fighter force. The Bf 109 first saw operational service during the Spanish Civil War (1939) and was still in service at the dawn of the jet age at the end of World War II (1945). It was one of the most advanced 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. From the end of 1941, the Bf 109 was steadily being supplemented by the superior Focke-Wulf Fw 190.
It was 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. The “Bf 109” designation was issued by the German ministry of aviation and represents the developing company Bayerische Flugzeugwerke and is a rather arbitrary figure.
