Patterned along the lines of the Caproni Ca.3 series of biplane bombers, the larger triplanes of the Ca.4 series were designed to be more effective in combat. Sometimes armed with up to eight machine guns, these cumbersome bombers were capable of accurately delivering large payloads of bombs to distant enemy targets. Although mainly used at night, they took part in daylight raids towards the end of the war. Of thirty-two Ca.42s manufactured in 1918, six of them were used by the Royal Naval Air Service.
