Jeanne d'Arc

Part of the Duguay-Trouin class light cruisers consisting of the Duguay-Trouin, Lamotte-Picquet and Primaguet, succeeded by the Jeanne d’Arc. Design progress started mid-1919 and in which Italy was considered to be the opponent especially in the control of the Mediterreanean. At the end of the same year was the Project 171 design completed but as the navy and the chief off the general staff had their objections was the design stricken in February 1920. Against the end that year were four designs available using the hull design of the American Omaha-class cruisers. Of these four designs was chosen for design C and two years was the building ordered although there were still objections against the design. For launching the 2 Gourdou-Leseurre GL-812 HY flying boats (later replaced by the GL-832) was on the quarter deck a catapult available.
