French destroyer Mécanicien Principal Lestin

The French destroyer Mécanicien Principal Lestin was the second of two Enseigne Roux-class destroyers built for the French Navy during the First World War.

Design and description
The Enseigne Roux class was an enlarged version of the preceding Bisson-class destroyer. The ships had an overall length of 82.6 m, a beam of 8.6 m, and a draft of 3 m. They displaced 850 t at normal load. Their crew numbered 76–81 men.

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 17000 shp which was intended to give the ships a speed of 30 kn. During her sea trials, Mécanicien Principal Lestin reached a speed of 31.2 kn. The ships carried enough fuel oil to give them a range of 1400 nmi at cruising speeds of 14 kn.

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

Construction and career
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.
