French destroyer Lansquenet (1909)

The Spahi-class was over 50 percent larger than the preceding Branlebas class to match the increase in size of foreign destroyers.[1] Lansquenet had an length between perpendiculars of 64 meters (210 ft), a beam of 6.6 meters (21 ft 8 in),[2] and a draft of 2.3 meters (7 ft 7 in). The ships displaced 530–550 metric tons (522–541 long tons) at deep load. Their crew numbered 77–79 officers and men.[1]

Lansquenet was powered by two triple-expansion steam engines, each driving one propeller shaft using steam provided by four Normand boilers. The engines were designed to produce 7,500 indicated horsepower (5,600 kW) which was intended to give the Spahi class a speed of 28 knots (52 km/h; 32 mph). During her sea trials, Lansquenet reached a speed of 28.84 knots (53.41 km/h; 33.19 mph). She carried more coal than her sister ships which gave her a range of 2,880 nautical miles (5,330 km; 3,310 mi) at a cruising speed of 10 knots (19 km/h; 12 mph).[3]

The primary armament of the Spahi-class ships consisted of six 65-millimeter (2.6 in) Modèle 1902 guns in single mounts, one each fore and aft of the superstructure and the others were distributed amidships. They were also fitted with three 450-millimeter (17.7 in) torpedo tubes. One of these was in a fixed mount in the bow and the other two were on single rotating mounts amidships.[1]

Lansquenet was ordered from Dyle et Bacalan and was launched at their shipyard in Bordeaux on 20 November 1909. She was completed in October 1910.[4]
