The Messerschmitt Bf-109 is a German metal-structure single-engine fighter in a low wing configuration with a classic tail. It turned out to be the basic and most produced Luftwaffe fighter during World War II. The flight of the prototype took place on May 29, 1935, and serial production continued in the years 1936-1945. In total, it is estimated that a total of about 35,000 Messerschmitt Bf-109 fighters of all varieties were produced, many of which ended up in the Czech and Israeli air forces after the war. The roots of the Bf-109 go back to the competition announced in 1933 by the Luftwaffe for a new fighter plane. In competition with the He-112, the Bf-109 project initially lost, but thanks to Willie Messerschmitt's intrigues, the project could continue and eventually he was the winner of the competition, becoming the Luftwaffe's primary fighter.
