The Canon de 138 mm Modèle 1893 was a medium-calibre naval gun of the French Navy used during World War I and World War II. It was carried by a number of ships built during the 1890s including the Charlemagne-class pre-dreadnought battleships. Guns from scrapped warships were later mounted on auxiliary ships during the 1930s.[1]

Design

The 45-calibre Mle 1893 used the typical built-up construction of its time. It had a screw breech and used separate-loading ammunition. In the battleships it was installed in armored casemates, using central pivot mounts, but no details are available.[2]

Ammunition

The 7.257-kilogram (16.00 lb) propellant charge for the Mle 1893 was contained in a cartridge case.[3]
