Caproni Ca.310

The Caproni Ca.4 was an Italian heavy bomber of the World War I era. A three-engine, twin-boom triplane of a wooden construction with a fabric-covered frame, armament consisted of four (but up to eight) Revelli 6.5 mm or 7.7 mm machine guns in front ring mounting and two boom ring mountings. Bombs were suspended in a bomb bay, which was a long and narrow container fixed to a lower wing. Photographs show at least four different arrangements with regard to the bombing nacelle.

The Italian Caproni was the only major bomber the Norwegians had available in their arsenal when the Germans invaded their country in 1939.
