The Fiat G.55 Centauro fighter was designed by Giuseppe Gabrielli at the Fiat factory in 1942 and flown in the spring of the same year (April 30). The plane was to be a response to the demand for an interceptor capable of operating at high altitudes, which was dictated by the increasing intensity of Allied air raids on Italian cities and military infrastructure. A total of 130 copies of this machine were produced.

Most Fiats G.55 were stationed in bases in northern Italy, from which they defended industrial plants located in these regions. The G.55 fighters were very highly rated by the pilots who considered them superior to the German Bf 109s G and K versions, and the Focke-Wulf Fw 190A. Unfortunately, due to the bombing of Fiat factories and problems with the supply of a sufficient number of Daimler Benz 603 engines, the production of the aircraft was stopped.
