Perspective

The Bouclier-class was nearly double the size of the preceding 450-metric-ton (443-long-ton) destroyers to match the increase in size of foreign destroyers. The French Navy issued a general specification that required oil-fired boilers, steam turbine propulsion and a uniform armament that allowed individual shipyards the freedom to design their ships as they saw fit. This allowed for some variations in size (from 72.32–78.3 meters (237 ft 3 in – 256 ft 11 in) in length) and machinery (Bouclier and Casque had three shafts, all the others had two, while Casque has three funnels, all the rest had four).[1]

Bouclier was the shortest ship with an overall length of 72.32 meters and her sister ships ranged in length from 74 to 78.3 meters (242 ft 9 in to 256 ft 11 in). All of the ships had beams of 7.6–8 meters (24 ft 11 in – 26 ft 3 in) and drafts of 2.9–3.3 meters (9 ft 6 in – 10 ft 10 in). Bouclier and her sister Francis Garnier had the lightest displacements at 692 metric tons (681 long tons); the others displaced 720–756 metric tons (709–744 long tons) at normal load. Their crews numbered 80–83 men.[1]

The destroyers were powered by two or three steam turbines of four different models, each driving one propeller shaft using steam provided by four water-tube boilers of four different types. The turbines 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). During their sea trials, they reached speeds of 29.3–35.5 knots (54.3–65.7 km/h; 33.7–40.9 mph). The ships carried 120–160 t (118–157 long tons) of fuel oil which gave 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]
