pedestal for the main armament was substituted in all ships except which received an enclosed mounting with a five-meter rangefinder. A high-angle rangefinder was fitted for the ant-aircraft guns. A torpedo director was located above the primary gunnery director on the foremast. It used a separate five-meter OPL Modèle 1935 stereoscopic rangefinder to provide the bearing and range to a Modèle 1933 electro-mechanical computer which calculated the torpedo firing angle. This was sent to the remotely controlled torpedo tubes, and the command to fire could be given by either the torpedo director or either of the secondary positions on the wings of the bridge. Modifications In early 1941 a pair of single mounts for Browning 13.2-millimetre AA machine guns were added to all ships on the quarterdeck. In late 1941, Le Hardi had her anti-aircraft suite reinforced and rearranged. The twin Hotchkiss machine gun mounts were repositioned on the quarterdeck and a pair of single mounts for Hotchkiss AA guns were installed in their place in front of the bridge. In addition the Browning machine guns were transferred to newly built platforms on the sides of the superfiring turret aft. Later in the year and in early 1942, L'Adroit, Casque and Mameluk received the same modifications. Revised design In 1938, after observing the experiences of ships attacked by aircraft while performing neutrality patrols during the Spanish Civil War of 1936–1939, the (Naval General Staff) revised its assumptions about a naval war. It now viewed a dual-purpose (DP) armament as a requirement for ships intended to escort capital ships. This was the role of the Le Hardi class and the staff wanted to evaluate how the four ships scheduled to be laid down in mid-1939 could be modified to accommodate the DP guns. Three proposals were submitted in response on 30 November, all on a hull that was enlarged by more than . The staff accepted two of them, the first for three ships to be armed with 130 mm DP mounts derived from those used on the Dunkerque-class battleships, while the remaining ship was to be armed with the standard 130 mm low-angle mounts to allow it to form a three-ship division with Le Corsaire and Le Flibustier, but its AA armament was to consist of a pair of twin-gun high-angle mounts, one of which replaced a torpedo-tube mount, and the standard pair of twin-gun AA machine gun mounts. Its
