History

The built-up guns were used on the two battleships of the Richelieu class, Richelieu and Jean Bart. They were mounted in quadruple turrets, which allowed mounting all the main battery at the bow, and saved weight on turret armour in the context of the Washington Naval Treaty.

During World War II seven guns were captured by the Germans and three of these were taken to Norway. It was planned to install them in a coastal battery at Vardaasen (MKB 6./501 Nötteröy), using Bettungsschiessgerüst (Firing platform) C/39 armoured single mounts, but the war ended before the battery became operational. In 1949 the guns were returned to France (in exchange for 3 German 38 cm SKC/34 from Todt Battery) where they were then refurbished at Ruelle.

Five guns remain: one is on display at the Arsenal of Brest, under Recouvrance Bridge; another at Lanvéoc at the École Navale; and a third gun survives at Gâvres, near Lorient.^[1] Two others are on display, at Ruelle and at La Spezia.^[2] The honour room of the École Navale also displays two 380mm shells and tampions.^[3]
