203mm/50 Modèle 1924 gun

With the signing of the Washington Naval Treaty of 1922 the Marine Nationale found itself with no 8-inch naval gun for mounting on the designated 10,000-ton cruiser. In order to maintain its position as a major naval power, it decided to develop one from scratch. Starting in 1924 they developed the 203mm/50 Modèle 1924 naval gun for use on the seven Treaty-class cruisers of the Marine Nationale. It was also modified for use on the Surcouf a French submarine built in the 1930s. The gun entered service on the Duquesne in 1928. The gun would remain in active service until 1948, when the last cruiser was placed in reserve. The gun was finally removed for inventory when the last treaty cruiser was towed for scrap in 1976.
