French destroyer Lion

The Guépard-class ships were improved versions of the preceding Jaguar class. They had an overall length of 130.2 meters (427 ft 2 in), a beam of 11.5 meters (37 ft 9 in),^[2] and a draft of 4.68 meters (15 ft 4 in). The ships displaced 2,436 metric tons (2,398 long tons) at standard load^[3] and 3,220 metric tons (3,170 long tons) at deep load. Their crew consisted of 10 officers and 200 crewmen in peacetime and 102 officers and 224 enlisted men in wartime.^[4]

The ships were powered by two geared steam turbines, each driving a propeller shaft using steam provided by four du Temple boilers. The turbines were designed to produce 64,000 metric horsepower (47,000 kW; 63,000 shp) which was intended give the ships a speed of 35.5 knots (65.7 km/h; 40.9 mph). During her sea trials on 24 September 1930, Lion sustained a speed of 35.47 knots (65.69 km/h; 40.82 mph) from 66,258 PS (48,733 kW; 65,352 shp). The ships carried enough fuel oil to give them a range of 3,000 nautical miles (5,600 km; 3,500 mi) at 14.5 knots (26.9 km/h; 16.7 mph).^[5]

The main battery of the Guépard class consisted of five 138.6-millimeter (5.5 in) Modèle 1923 guns in single shielded mounts, one superfiring pair fore and aft of the superstructure and the fifth gun abaft the rear funnel. Their anti-aircraft armament consisted of four semi-automatic 37-millimeter (1.5 in) Modèle 1927 guns in single mounts positioned amidships. They were equipped with two rotating triple mounts for 550-millimeter (21.7 in) torpedo tubes, one mount between the two pairs of funnels as well as another aft of the rear funnel. A pair of depth charge chutes were built into their stern; these housed a total of sixteen 200-kilogram (440 lb) depth charges, with eight more in reserve. They were also fitted with four depth-charge throwers, two on each side abreast the forward pair of funnels, for which the ships carried a dozen 100-kilogram (220 lb) depth charges.^[6]
