lorrain 1913 model 1912 340mm turrets
The guns could fire a 1,200-pound shell to 15,000 yards, limited due to the 12-degree elevation of their turret. This was later modified to 18 degrees in a 1920s refit, which produced a range of 20,000 yards. In the 1930s, the Bretagne-class received the slightly more modern Model 1912M version of the guns originally intended for the scrapped Normandie-class battleships, and their elevation was increased again, to 23 degrees, allowing for 25,000-yard shots. Each tube could fire every 35 seconds and the magazine held 100 shells per gun.
