The Caproni Ca.37 was a ground attack aircraft designed and built in Italy by Caproni around 1916.

Design and development

During 1916 Caproni embarked on the design of a small light ground attack aircraft which followed the design philosophy of its much larger cousins the Ca.3 and Ca.4.

The Ca.37 followed the twin boom layout with central nacelle, which housed the tandem cockpits and the 190 kW (250 hp) Lancia Tipo 4 6-cylinder in-line piston engine, driving a 2-bladed pusher propeller. The tail-plane spanned across the two tail-booms and mounted two all-flying rudders for yaw control. Twin main-wheel units were strut mounted under each boom which also carried wooden tail-skids.

The front cockpit was to house a gunner with a flexibly mounted machine-gun. Small bombs were also to be carried for trench attacks and anti-personnel attacks.

Limited further development, in the form of streamlined pod and booms, was carried out as the Ca.38, but no production resulted.

Variants

Ca.38
