Nakajima Ki-43 II Hayabusa

The Nakajima Ki-43 Hayabusa (Falcon) fighter, nicknamed Oscar in Allied code, was Japan's equivalent of the Spitfire and the Messerschmitt Bf-109 - it was a core piece of the Imperial Japanese Army Aviation throughout the Second World War, and was refined and produced in successive versions during all that period. Although it remained somewhat in the shadow of the naval Mitsubishi Zero, famous on the Pacific front thanks to its spectacular carrier battles, the Hayabusa played a major role in the battles over the Asian continent: over China, Burma, Malaya, but also over the Philippines and New Guinea. There it fought effectively against the air forces of China, the USA, Great Britain, Australia and the Netherlands, making a major contribution to the initial great victories of the Japanese.

The Ki-43 fighter was developed in the late 30s at the Nakajima factory under the direction of Hideo Itokawa, based on experience with the highly successful Ki-27 airframe, which had proved excellent in combat over China. The design of the Ki-43 was based on the specific concept of a light aircraft, with excellent manoeuvrability and climb and good speed, achieved at the cost of a rather fragile structure, weak armament and virtually no armour. This corresponded to the Japanese doctrine of sophisticated manoeuvre combat, requiring masterful training and great courage of the pilots. Interestingly, the Hayabusa was powered by the same engine as the Zero. In the early period of the war, when the Japanese armies were conquering more and more areas of Southeast Asia, the Ki-43 was a match for its opponents, easily defeating Hurricanes or Buffalos. Later, however, the Oscars became increasingly obsolete and their lightweight construction did not allow for major improvements. In 1944 they began to be replaced on the main production lines and in combat units by the excellent Ki-84 Hayate, but until the end of the war their production was maintained and they were also used in combat, including in Kamikaze units.
