The Requin-class submarines were a class of nine diesel-electric attack submarines built for the French Navy in the mid-1920s. Most saw action during World War II for the Vichy French Navy or the Free French Naval Forces. Nine ships of this type were built in the shipyards of Brest, Cherbourg and Toulon between 1923 and 1928. The class was part of the French Marine Nationale, serving in the Mediterranean Sea. All member ships took part in World War II, fighting on both sides of the conflict; Four were captured by Italian forces and sunk by the Allies. Only one ship survived the war - Marsouin, decommissioned shortly after the war's end.
