The Le Hardi class was designed to escort the fast battleships of the Dunkerque class and to counter the large destroyers of the ItalianNavigatori and JapaneseFubuki classes.[1] The ships had an overall length of 117.2 meters (384 ft 6 in), a beam of 11.1 meters (36 ft 5 in),[2] and a draft of 3.8 meters (12 ft 6 in). The ships displaced 1,800 metric tons (1,772 long tons) at standard and 2,577 t (2,536 long tons) at deep load. They were powered by two geared steam turbines, each driving one propeller shaft, using steam provided by four Sural-Penhöetforced-circulation boilers. The turbines were designed to produce 58,000 metric horsepower (42,659 kW; 57,207 shp), which was intended to give the ships a maximum speed of 37 knots (69 km/h; 43 mph). Le Hardi, the only ship of the class to run sea trials, comfortably exceeded that speed during her trials on 6 November 1939, reaching a maximum speed of 39.1 knots (72.4 km/h; 45.0 mph) from 60,450 metric horsepower (44,461 kW; 59,623 shp). The ships carried 470 metric tons (463 long tons) of fuel oil which gave them a range of 3,100 nautical miles (5,700 km; 3,600 mi) at 10 knots (19 km/h; 12 mph). The crew consisted of 10 officers and 177 enlisted men.[3]
Unlike most of the ships in Toulon, Bison was undamaged when the Germans attempted to capture the French ships there on 27 November 1942 because she was still in reserve and did not have any crew assigned to scuttle her. The Italians rejected a German request to complete her and redesignated her as FR35. After the Italian armistice in September, she was used as a smoke-generatorhulk by the Germans. She was first damaged during an Allied air raid in early 1944 and then by a collision with a German submarine on 25 June. The ship sank in the commercial port of Brégaillon-Toulon; she was refloated the following year and scrapped.[6]
