Canon de 274 modèle 1893/1896

The Canon de 274 modèle 1893/1896 were a family of French naval guns developed in the years before World War I that armed a variety of warships of the French Navy. Guns salvaged from scrapped ships found a second life as coastal artillery and railway artillery during World War I.

Design

The mle 1893/1896 guns were typical built-up guns of the period with several layers of steel reinforcing hoops. The guns used an interrupted screw breech and fired separate loading bagged charges and projectiles. They were shorter and lighter than the preceding Canon de 274 modèle 1887/1893 and despite being shorter they used a larger propellant charge which gave them higher muzzle velocity and range than their predecessors.

Mle 1893/1896 guns armed coastal defense ships, ironclads and pre-dreadnoughts of the French Navy built or refit between 1887-1905.[1]

Coastal defense ships

  • Terrible Class - Three ships of this class the Caïman, Indomptable, and Requin received two single mount mle 1893/1896 guns during refits in 1901.

Ironclads

  • Redoutable - This ship received three mle 1893/1896 guns in single mounts after an 1894 refit.

Pre-dreadnoughts

Railway guns

During World War I four guns were removed from Caïman and Indomptable and converted by Schneider to railway guns. These were designated Canon de 274 modèle 93/96 Berceau and they were widely used. When their barrels were worn they were bored out to 285–288 mm (11.2–11.3 in) and given new ammunition.[3]

Ammunition

Ammunition was of separate loading type with a bagged charge and projectile. The charge weighed 85 kg (187 lb).

The guns were able to fire:
