Hispano-Suiza Model 8 Ca

In 1917 Hispano-Suiza developed the Model 8 Ca, which featured an innovative cast-aluminum cylinder construction with internal water passages. It also had a 37 mm Puteaux cannon mounted between the cylinder banks that could fire through the hollow propeller shaft. French ace Georges Guynemer used the first of these “moteurs-canon,” or cannon engines, on a SPAD XII and shot down one enemy aircraft. French aces Charles Nungesser and Rene Fonck also used cannon-equipped SPADs.

The cannon fired only one shot at a time, an extreme disadvantage in combat. Development of the cannon engines continued through the Hispano-Suiza Model K, an experimental engine designed to carry a fully automatic 37 mm cannon.
