The French cruiser Dupleix was the fourth vessel of the Suffren class, built as a treaty cruiser with notable specifications and a service history marked by wartime activities and damage. She was constructed with a focus on protection against 155 mm shells at 18,000 meters, featuring increased armor thickness and an armor layout similar to her sister ship Foch. Her armament included twin 1930 mounts for secondary weapons, with four quad 13.2 mm machine guns fitted on the bridge structure, although their installation remains uncertain. She was launched on 9 October 1930 after being ordered in April 1929 and was commissioned on 5 May 1932, entering service in November 1933. Dupleix was assigned to the First Light Division at Toulon and participated in various peacetime activities, including a naval review in 1935 and cooperation with film productions depicting naval life. In 1937, she was part of the reformed First Cruiser Division alongside Colbert and Algérie, undergoing a major refit that year. At the outbreak of World War II, Dupleix was based in Toulon, actively engaged in patrol and escort missions, notably participating in the hunt for the German pocket battleship Graf Spee and operations off West Africa. She was involved in the bombardment of Vado, Italy, in June 1940, which was her only active combat firing during the war. Following the Franco-German Armistice, she remained at Toulon until the fleet was scuttled in November 1942 to prevent capture by German forces. Subsequently, she was raised by Italians in 1943, but her service was interrupted when she was bombed and sunk in 1944. She was later salvaged and scrapped in 1951. Throughout her career, Dupleix exemplified the interwar French naval design and played a role in the early naval engagements of WWII, representing France's efforts to modernize and adapt her cruiser force amidst evolving maritime threats.
