"France" sank after striking a rock in Quiberon Bay in 1922. Between the wars the surviving ships were modernised several times, but they were not rebuilt thoroughly enough to prevent them from becoming obsolete in comparison to modern German or Italian battleships. They were relegated to training duties during the 1930s. "Courbet" and "Paris" escaped to Portsmouth where they became depot and accommodation ships after the French armistice in 1940. "Jean Bart" was demilitarised, renamed "Océan", and became a school hulk in Toulon. She was captured there on 27 November 1942, although she was not scuttled. She was used for experiments with large shaped charge warheads by the Germans until she was sunk by the Allies in 1944, later broken up in place in 1945. "Courbet" was scuttled on 9 June 1944 as a breakwater for a Mulberry harbour used during the Battle of Normandy.
