thirteen sessions on gunnery ranges. The primary anti-aircraft (AA) armament of the Le Hardi-class ships was intended to consist of a twin-gun mount for 70-caliber Canon de Modèle 1935 guns. Development of the automatic weapon was still in progress when the ships were completed in 1939–1940 and a twin-gun mount for 50-caliber Canon de 37 mm Modèle 1933 guns on the aft superstructure was installed instead. These manually-loaded guns could elevate to a maximum of +80° and they had a practical rate of fire of 15–21 rounds per minute. The ships carried a total of 2,960 rounds for the guns. Their muzzle velocity of gave their shells an effective range of . The ships were also fitted with two twin Hotchkiss Modèle 1929 anti-aircraft machine gun mounts abreast the bridge. The weapons had a practical rate of fire of 250 rounds per minute and an effective range of . Ready-use lockers stowed 480 rounds near each gun and the remaining 1,920 rounds per gun were in the magazine. The ships carried one triple and two twin sets of torpedo tubes amidships; the twin-tube aft mounts were positioned one on each broadside, but the triple-tube forward mount could traverse to both sides. One depth charge chute was built into the stern in the first batch of six ships; this housed eight depth charges. The other side of the stern was used for the handling gear for a towed Ginocchio captive anti-submarine torpedo, but this was removed before they were completed. The second batch of six ships had two depth charge chutes in the stern with a capacity of a dozen depth charges. Fire control The fire-control system of the Le Hardi class as designed was identical to that of the larger s with a director equipped with a OPL Modèle PC.1936 stereoscopic rangefinder built around the base of the foremast above the bridge. The director sent the range to the where it was fed into a Modèle 1929 electro-mechanical computer which calculated the firing solution and transmitted it to the turrets. The intended to equip the turrets so they could be controlled by the director, but abandoned the effort in 1942 after equipment trials were unsuccessful and it concluded that the ships lacked the necessary electrical capacity. Space and weight had been allocated for a director for the 37-millimetre Modèle 1935 guns, but when this was unavailable a rangefinder on a
