The turbines were designed to produce 31,000 metric horsepower (22,800 kW; 30,576 shp), which would propel the ships at 33 knots (61 km/h; 38 mph).

[1] The main armament of the L'Adroit-class ships consisted of four Canon de 130 mm (5.1 in) mm Modèle 1924 guns in single mounts, one superfiring pair each fore and aft of the superstructure.

For defense against strafing aircraft the ships were equipped with a pair of mounts for two or four 8-millimeter (0.315 in) Hotchkiss Mle 1914 machine guns abreast the bridge.

In addition two Thornycroft depth-charge throwers were fitted at the end of the forecastle for which six 100-kilogram (220 lb) depth charges were carried.
