Dehorter was one of a dozen Bouclier-class destroyers built for the French Navy in the first decade of the 20th century.

Design and description

[edit]

The Bouclier class were designed to a general specification and varied significantly from each other in various ways.[1] The ships had an overall length of 74–78.3 meters (242 ft 9 in – 256 ft 11 in), a beam of 7.6–8 meters (24 ft 11 in – 26 ft 3 in), and a draft of 2.9–3.1 meters (9 ft 6 in – 10 ft 2 in). Designed to displace 800 metric tons (787 long tons), they displaced 720–756 t (709–744 long tons) at normal load. Their crew numbered 80–83 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 13,000 shaft horsepower (9,700 kW) which was intended to give the ships a speed of 30 knots (56 km/h; 35 mph). Dehorter only reached 29.3 knots (54.3 km/h; 33.7 mph) during her sea trials. The ships carried enough fuel oil to give them a range of 1,200–1,600 nautical miles (2,200–3,000 km; 1,400–1,800 mi) at cruising speeds of 12–14 knots (22–26 km/h; 14–16 mph).[2]

The primary armament of the Bouclier-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.[1]

During World War I, a 45-millimeter (1.8 in) or 75-millimeter (3 in) anti-aircraft gun, two 8-millimeter (0.31 in) machine guns, and eight or ten Guiraud-type depth charges were added to the ships. The extra weight severely overloaded the ships and reduced their operational speed to around 26 knots (48 km/h; 30 mph).[1]

Construction and career

[edit]

Dehorter was ordered from Ateliers et Chantiers de Penhoët and was launched from its Saint-Nazaire shipyard on 18 April 1912. The ship was completed the following year.[3] When the First World War began in August 1914, Dehorter was the flagship (chef de division) for the Group of Submarines and Destroyers (Flottille de sous-marins et torpilleurs) of the 1st Naval Army (1ère Armée Navale).[4]
