The French cruiser Dupleix was one of three Dupleix-class armoured cruisers built for the French Navy in the first decade of the 20th century.
Designed by the naval architect Emile Bertin, the Dupleix-class ships measured 132.1 meters (433 ft 5 in) long overall with a beam of 17.9 meters (58 ft 9 in) and had a maximum draft of 7.4 meters (24 ft 3 in). They displaced 7,735 metric tons (7,613 long tons). They had a crew of 531 or 580 officers and enlisted men.
The ships had three vertical triple-expansion steam engines, each driving a single propeller shaft. Steam for the engines was provided by 20 or 24 boilers and they were rated at a total of 17,500–17,800 indicated horsepower (13,000–13,300 kW) that gave them a speed of 20.7–21 knots (38.3–38.9 km/h; 23.8–24.2 mph). The Dupleix-class ships carried up to 1,180 metric tons (1,160 long tons; 1,300 short tons) of coal and could steam for 7,600 nautical miles (14,100 km; 8,700 mi) at a speed of 10 knots (19 km/h; 12 mph).
The ships of the Desaix class had a main armament that consisted of eight quick-firing (QF) 45-caliber Canon de 164 mm Modèle 1893-96 guns. They were mounted in four twin gun turrets, one each fore and aft of the superstructure and a pair of wing turrets amidships. For anti-torpedo boat defense, they carried four 45-caliber QF 100-millimeter (3.9 in) guns on the forecastle deck, ten QF 47-millimeter (1.9 in) Hotchkiss guns. They were also armed with two above water 450-millimeter (17.7 in) torpedo tubes.
