The Mitsubishi A6M Reisen (other names: Zero or Zeke) is a Japanese, single-engine, all-metal low-wing fighter aircraft from the Second World War. The flight of the prototype took place on April 1, 1939, and it was put into service in the summer of 1940. The first prototypes were powered by a Mitsubishi Zuisei 13 engine, but from the A6M2 model 11 onwards, the Nakajima NK1B Sakae 12 engine with 950KM was used, which made the aircraft one of the best we early war period plum town. New versions were written just before and during the war. One of the most famous was the A6M2 model 21, prepared at the beginning of the Pacific war, its special version with folding wings for aircraft carriers, which became the basic Japanese on-board fighter. The next versions are A6M3 and A6M5, each of which had several versions. The first one used the 1130 HP Nakajima Sakae 21 engine with a compressor, which, however, meant an increase in weight and a decrease in range and maneuverability.
