Production of 283 examples of the C.R.32bis followed for the Regia Aeronautica, this having the improved 600 hp A 30 RAbis engine, an armament of two 0.303 in (7.7 mm) and two 0.50 in (12.7 mm) machine guns, and more minor changes. Forty-five similar fighters were supplied to Austria and 52 to Hungary (the latter eventually receiving 38 of those originally purchased by the former). The C.R.32ter, of which 150 were produced for the Regia Aeronautica in July-December 1937, reverted to the twin 0.50 in (12.7 mm) machine guns armament, and featured improved gunsight and instrumentation. The definitive model for the Italian air arm was the similarly-armed C.R.32quater, of which 337 were delivered to the Regia Aeronautica, similar aircraft being purchased by Paraguay and Venezuela, which received five and nine respectively.
A total of 377 C.R.32s fought with Italian and Spanish units over Spain, and 100 C.R.32quater fighters were license-built in Spain by Hispano-Suiza during 1940-1943, forty of these subsequently being converted as two-seaters. Production of the C.R.32 totaled 1,211 aircraft. The following data relate to the C.R.32ter."
