French destroyer Mécanicien Principal Lestin

The Enseigne Roux class was an enlarged version of the preceding Bisson class. The ships had an overall length of 82.6 meters (271 ft 0 in), a beam of 8.6 meters (28 ft 3 in), and a draft of 3 meters (9 ft 10 in). They displaced 850 metric tons (837 long tons) at normal load. Their crew numbered 76–81 men.[1]

The ships were powered by a pair of Parsons steam turbines, each driving one propeller shaft using steam provided by four water-tube boilers. The engines were designed to produce 17,000 shaft horsepower (13,000 kW) which was intended to give the ships a speed of 30 knots (56 km/h; 35 mph). During her sea trials, Mécanicien Principal Lestin reached a speed of 31.2 knots (57.8 km/h; 35.9 mph).[2] The ships carried enough fuel oil to give them a range of 1,400 nautical miles (2,600 km; 1,600 mi) at cruising speeds of 14 knots (26 km/h; 16 mph).[1]

The primary armament of the Enseigne Roux-class ships consisted of two 100-millimeter (3.9 in) Modèle 1893 guns in single mounts, one each fore and aft of the superstructure, and four 65-millimeter (2.6 in) Modèle 1902 guns distributed amidships. They were also fitted with two twin mounts for 450-millimeter (17.7 in) torpedo tubes amidships.[2]

Mécanicien Principal Lestin was ordered from the Arsenal de Rochefort and was laid down on 12 November 1913. The ship was launched on 15 May 1915 and completed the following year. She was initially assigned the Mediterraneand Fleet and was transferred to the Dunkirk Flotilla defending the English Channel in 1918.[3]
