Design and description

Sister ship Bisson in harbor

The Bisson class were enlarged versions of the preceding Bouclier class built to a more standardized design. The ships had a length between perpendiculars of 78.1 meters (256 ft 3 in), a beam of 8.6 meters (28 ft 3 in), and a draft of 3.1 meters (10 ft 2 in). Designed to displace 850–880 metric tons (837–866 long tons), they displaced 756–791 t (744–779 long tons) at normal load. Their crew numbered 80–83 men.

Commandant Lucas was powered by a pair of Breguet steam turbines, each driving one propeller shaft using steam provided by four Indret water-tube boilers. The engines were designed to produce 15,000 shaft horsepower (11,000 kW) which was intended to give the ships a speed of 30 knots (56 km/h; 35 mph). During her sea trials, Commandant Lucas reached a speed of 30.02 knots (55.60 km/h; 34.55 mph). The ships carried enough fuel oil to give them a range of 1,450 nautical miles (2,690 km; 1,670 mi) at cruising speeds of 14 knots (26 km/h; 16 mph).

The primary armament of the Bisson-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.

Construction and career

Commandant Lucas was ordered from the Arsenal de Toulon and was launched on 11 July 1914. The ship was completed later that year.
