Only 10 Fiat CR.25s were ever built. Originally intended as a reconnaissance-bomber, the ten aircraft ended their days shuttling VIPs between Mussolini’s Italy and Nazi Germany.
First flying in 1937, the aircraft was generally well liked by its pilots but this was not enough to encourage further orders. Despite this, the 10 aircraft were built in three distinct variants excluding the two initial prototypes. The CR.25bis was the main variant and was a strategic reconnaissance and long-range escort fighter aircraft. The 10th aircraft was reworked into the first transport aircraft and redesignated CR.25D. It was primarily used as a transport for the Italian air attaché in Berlin. The most promising variant was the CR.25quater, flown in 1940, which was a more heavily armed version with a slight increase in wing area but it failed to attract anymore orders.

Imperial Japanese Air Force
Not as far fetched as you might think. The Japanese actually flew Fiat BR.20 bombers against the Chinese from 1937. Japan was desperately short of modern long range bombers at the time and Mussolini promised to prioritise any Japanese order for bombers even over his own air force. Although phased out of frontline use by Pearl Harbour, the aircraft still received an Allied codename – “Ruth”.

Latvian Naval Aviation
Had Latvia acquired the CR.25 toward the end of the 1930s then they would not have lasted long as they would have been captured by the Soviets when they annexed the small Baltic country in 1940.
