Development and design

A Caproni Ca.1 equipped with three Gnome rotary engines

Constructed as a fabric-covered wooden biplane, the Ca.1 featured a tri-motor configuration. Its open central nacelle accommodated a crew of four: two pilots, a forward gunner, and a rear gunner-mechanic who operated the upper machine guns while positioned atop the central engine within a protective cage, situated just ahead of the rear propeller. The aircraft employed a tricycle landing gear arrangement.

Prior to World War I, Italy and Russia pioneered efforts to develop heavy bomber capabilities. The initial heavy bomber designed by Gianni Caproni was a twin-boom biplane with three 67 kW (80 hp) Gnome rotary engines arranged sequentially within a central nacelle: the rearmost engine powered a pusher propeller, while the other two drove tractor propellers mounted at the front of each boom. This model, known by Caproni as the Caproni 260 hp and later designated after the war as the Ca.30, underwent flight trials in a slightly revised version (termed the Ca.31) in October 1914.

Flight testing demonstrated that the power output was inadequate and that the engine configuration was problematic. Consequently, Caproni revised the design by keeping the pusher engine in its original position but relocating the other two engines to the front of each boom, directly driving their respective propellers. Equipped with more powerful inline engines, this updated model, referred to as the Caproni 300 hp (later known as the Ca.32), attracted interest from the Italian Army’s aviation branch, which adopted it under the designation Ca.1. Between August 1915 and December 1916, 166 units were produced.

Following the war, several Ca.1 aircraft were converted into airliners capable of transporting up to six passengers; this modification was identified as the Ca.56 in Caproni’s postwar classification system.

Discrepancies exist among published references concerning early Caproni designations, largely due to three distinct naming conventions applied: Caproni’s internal designations at the time, those assigned by the Italian Army, and retrospective designations established by Caproni for earlier models after the war.

Operational history

The Ca.1 was introduced into service with the Italian Army around mid-1915 and made its combat debut on August 20, 1915, targeting the Austrian airfield at Aisovizza. Ultimately, fifteen bomber squadrons (numbered 1 through 15 Squadriglia) were outfitted with Ca.1, Ca.2, and Ca.3 bombers, primarily conducting bombing missions against locations within Austria-Hungary. The 12th squadron was deployed in Libya, while in 1918, three squadrons (3rd, 14th, and 15th) were active in France.
