==Design and description==
The ''Dupleix''-class ships were much smaller and more lightly armed than ''Jeanne d'Arc''. They measured {{convert|132.1|m|ftin|sp=us}} [[Length overall|long overall]]<ref name=s9>Silverstone, p. 79</ref> with a [[beam (nautical)|beam]] of {{convert|17.8|m|ftin|sp=us}} and had a maximum [[draft (ship)|draft]] of {{convert|7.46|m|ftin|sp=us}}. The cruisers [[Displacement (ship)|displaced]] {{convert|7700|t|LT|sp=us|0}} as designed. To reduce [[biofouling]], their hulls were sheathed in [[teak]]. The ships normally had a crew of 19 officers and 550 enlisted men, but accommodated 24 officers and 583 enlisted men when serving as flagships.<ref>Jordan & Caresse, pp. 82, 91</ref>
The ships' propulsion machinery consisted of three [[Marine steam engine#Triple or multiple expansion|vertical triple-expansion steam engine]]s, each driving a single [[propeller shaft]], using steam provided by [[water-tube boiler]]s, but the types of machinery differed between them. The first two ships, {{Ship|French cruiser|Dupleix||2}} and {{Ship|French cruiser|Desaix||2}}, had four-cylinder engines fed by 24 [[Belleville boiler]]s with a working pressure of {{convert|20|kg/cm2|kPa psi|0|abbr=on|lk=on}} while the last ship, {{Ship|French cruiser|Kléber||2}}, had three-cylinder engines that used 20 [[Niclausse boiler]]s at {{convert|18|kg/cm2|kPa psi|0|abbr=on}}. The engines of all three ships were designed to produce a total of {{convert|17100|PS|lk=on|sp=us}} that was intended to give them a maximum speed of {{convert|21|kn|lk=in}}. Despite exceeding their horsepower rating, only ''Kléber'' met or exceeded her designed speed during their [[sea trial]]s, the ships attaining {{convert|20.6|-|21.5|kn}} from {{convert|17177|-|17870|PS|sp=us}}. The sisters carried up to {{convert|1200|t|sp=us}} of coal and could steam for {{convert|6450|nmi|lk=in}} at a speed of {{convert|10|kn}}.<ref>Jordan & Caresse, pp. 82, 94</ref>
