The Caproni Ca.5 was an Italian heavy bomber of World War I and the postwar era.
By late World War I, developments in aircraft technology made older bomber designs unable to penetrate targets defended by modern fighters.
Apart from greater power, various refinements were made to the design, including modifications to the main nacelle and undercarriage, and completely new wings.
The crew of four was placed in an open central nacelle (front gunner, two pilots and rear gunner-mechanic).
The rear gunner manned upper machine guns, standing upon the central engine in a protective "cage", just before a propeller.
