Design and description

The Spahi-class was over 50 percent larger than the preceding Branlebas class to match the increase in size of foreign destroyers.[1] Enseigne Henry had an length between perpendiculars of 65.8 meters (215 ft 11 in), a beam of 6.6 meters (21 ft 8 in),[2] and a draft of 2.4 meters (7 ft 10 in). The ships displaced 530–550 metric tons (522–541 long tons) at deep load. Their crew numbered 77–79 officers and men.[1]

Enseigne Henry was powered by two triple-expansion steam engines, each driving one propeller shaft using steam provided by four Guyot 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, Enseigne Henry reached a speed of 28.46 knots (52.71 km/h; 32.75 mph). The ships carried enough coal to give them a range of 1,000–1,200 nautical miles (1,900–2,200 km; 1,200–1,400 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]

Construction and career

Enseigne Henry was ordered from the Arsenal de Rochefort and was launched on 12 May 1911. She was completed in April 1912.[4]

gollark: I mean, most of us would have internet connectivity anyway, VPSes are very cheap if you know where to look, and electricity is probably only a few £/month.
gollark: Excellent!
gollark: Ugh, bee discord and/or poor internet connectivity.
gollark: ¡¡¡
