The Fiat CR.32, a compact and agile biplane fighter designed by Celestino Rosatelli, was already considered obsolete by the outbreak of World War II.
Nevertheless, it remained in service with several air forces and saw combat in multiple theatres.
Pre-War Legacy
The CR.32 gained fame during the Spanish Civil War (1936–1939), where Italy deployed over 380 aircraft to support Franco’s Nationalists.
Its performance against Soviet-supplied aircraft earned it a reputation as one of the finest biplane fighters of its time.
By 1939, two-thirds of the Regia Aeronautica’s fighter strength still consisted of CR.32s, with 294 stationed in Italy and North Africa and 34 in Italian East Africa.
WWII Combat Service
North Africa & Mediterranean
The CR.32 participated in early clashes against British aircraft, including successful engagements against Bristol Blenheim bombers and even Hawker Hurricanes.
In one notable encounter, six CR.32s downed two Blenheim’s without loss.
Albania & Balkans
The aircraft supported Italian operations during the invasion of Albania and later in the Balkans, though its limited speed and firepower made it vulnerable to newer monoplane fighters.
Italian East Africa
CR.32s flew defensive and reconnaissance missions, often facing logistical challenges and overwhelming Allied air superiority.
Hungary & Germany
Austrian CR.32s were absorbed into the Luftwaffe after the Anschluss but saw little use.
Germany later transferred some to Hungary, where they were used for training and secondary roles.
Decline and Retirement
As monoplane fighters like the Macchi C.200 and Fiat G.50 entered service, the CR.32 was gradually relegated to training, liaison, and rear-area defence roles.
Despite its obsolescence, the aircraft remained in limited use until 1943, with some surviving in Spanish service until the 1950s.
