Caproni Ca.311

The Caproni Ca.311 was a light bomber-reconnaissance aircraft produced in Italy prior to and during World War II. It was a member of the large family of Caproni designs derived from the Ca.306 airliner prototype of 1935, and more directly a modification of the Ca.310 bomber. As with other related types, it was a low-wing cantilever monoplane of conventional design. This particular design incorporated the Ca.310's retractable main undercarriage, as well as the heavily glazed nose that had been tested on the Ca.310bis prototype. New features included a relocation of the dorsal turret to a position immediately aft of the cockpit, and additional glazing throughout the fuselage.

From 1940, this aircraft began to replace the IMAM Ro.37 in service, completing this process the following year.
