From the wartime G.55 fighter the Fiat company developed the postwar G.55A single seat fighter/trainer and G.55B dual trainer, both with 1310 hp Fiat RA. 1050 (licence built Daimler Benz 605) engine.
In 1948 the engine was switched to the Rolls Royce Merlin T.24 or Mk 500, rated at 1630 hp, the former being fitted to the G.59 1 and 2 and the Mk 500/20 the 3 and 4. The 4 had a lower rear fuselage to match a blister hood. In each case the suffix A denoted a single seater and B a dual two-seat version. Single seat versions could have two 20 mm (0.79 in) Hispano cannon and camera gun, and racks for two 100 kg (220 1b) bombs.
Production G.59s were delivered to Italy and Syria. A proposed family of true fighter derivatives with 2000 hp Packard V¬1650 11 (Merlin) engines was not proceeded with.
Among the customers were Argentina, Egypt and Syria.
