Caproni altered the aircraft, retaining the pusher engine in its original location and moving the other two engines to the front of the booms, directly driving the propellers.

. Some Ca.1s survived the war to be rebuilt as airliners, able to carry up to six passengers. This conversion became known as the Ca.56 in Caproni's postwar naming scheme. There is some variation in published sources over early Caproni designations. The confusion stems, in part, from three separate schemes used to designate these aircraft – Caproni's in-house designations of the time, those used by the Italian Army, and designations created after the war by Caproni to refer to past designs.

Operational history

The Ca.1 entered service with the Italian Army in the middle of 1915 and first saw action on August 20, 1915, attacking the Austrian air base at Aisovizza. Fifteen bomber squadrons (1-15 ''Squadriglia'') were eventually equipped with Ca.1, Ca.2, and Ca.3 bombers, bombing mostly targets in
