CRDA CANT 25 (Italy)
Of the world's major military powers between the two World Wars, only Italy persisted with the single-seat fighter flying-boat. An outstanding example was the CANT 25, a slim sesquiplane with a single-step hull, Warren-girder
wing bracing and an open cockpit for the pilot just in front of the lower wing leading edge. The prototype was followed by the CANT 25M, which entered service with the Regia Aeronautica in 1931. Powered by a 305.5 kW (410 hp) Fiat A. 20 water-cooled engine driving a two-blade pusher propeller, it was armed with two 7.7 mm (0.303 in) Vickers machine-guns fixed in the bow and firing forward.
The CANT 25AR version also went into production. It had conventional wing strutting and folding wings for shipboard stowage. Structural strengthening permitted catapult launching. A number of CANT 25s survived as trainers up to 1940.
