Canon de 138 mm Modèle 1893 naval gun

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 pre-dreadnought battleships. Guns from scrapped warships were later mounted on auxiliary ships during the 1930s.

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.

Ammunition
The 7.257 kg propellant charge for the Mle 1893 was contained in a cartridge case.
