Design and description
[edit]The Georges Leygues-class ships were designed as anti-submarine (ASW) escorts for the fleet.[1] They had an overall length of 139 metres (456 ft), a beam of 14 m (45 ft 11 in) and a draught of 5.7 m (18 ft 8 in). The ships had a standard displacement of 3,830 tonnes (3,770 long tons) and 4,500–4,580 tonnes (4,430–4,510 long tons) at full load. The Georges Leyguess' propulsion machinery used a CODOG configuration with one SEMT-Pielstick 16PA6-V280 diesel engine and a Rolls-Royce Olympus TM3B gas turbine were coupled to each of the two propeller shafts. The diesels were used for speeds under 21 knots (39 km/h; 24 mph) and the gas turbines for sprints up to 30 knots (56 km/h; 35 mph). The diesels were rated at a total of 12,800 metric horsepower (12,600 bhp; 9,400 kW) and the turbines at a total of 46,200 shp (46,800 PS; 34,500 kW).[2] The combination give the ships a range of 9,500 nautical miles (17,600 km; 10,900 mi) at 17 knots (31 km/h; 20 mph). The frigates had a complement of 216 sailors.[1]
The primary anti-ship weapon of the Georges Leyguess consisted of four single box launchers for MM38 Exocet anti-ship missiles, located aft of the funnel with two launchers on each broadside. The frigates were designed with a single 100-millimetre (3.9 in) Modèle 1968 dual-purpose gun in a single-gun turret forward of the superstructure. They were also equipped with two 20 mm (0.8 in) guns. The ships were fitted with a octuple Crotale anti-aircraft missile launcher with 26 reloads located on the aft superstructure. The anti-submarine| (ASW) weapons of the Georges Leygues-class ships consisted of two torpedo launchers , one on each side of the ship. Each ship carried ten torpedoes. The ships were designed to carry helicopters, a pair of Westland Lynx ASW helicopters in a double hangar at the stern.[1][2]
They were completed with a DRBV 51C search radar, a DRBC 32E fire-control radar and a DRBV 26 early-warning radar. For anti-submarine warfare, they were equipped with a DUBV 23B hull-mounted sonar and DUBV 43B towed variable depth sonar. For electronic defence, the vessels mounted two Syllex chaff launchers. The SENIT 4 tactical data system coordinated sensor data.[1][2]
Construction and career
[edit]Dupleix was built by the Arsenal de Brest with her keel being laid down on 17 October 1975. The vessel was launched on 2 December 1978 and was commissioned on 13 June 1981.[1] The ship was decommissioned in 2014, and taken to Saint-Mandrier, to replace the ex-Rance at the diving school located there.[3]
