the depth-charge throwers were removed in 1936 and more 200-kilogram depth charges were carried in their place. the navy reconsidered its anti-submarine warfare tactics after the war began in september and intended to reinstate the depth-charge throwers, although these were an older model than the one previously installed; "le chevalier paul" had not received hers before her loss. as an interim measure, a pair of rails were installed on the stern for depth charges. each rail could accommodate three depth charges and ten more were stored in the magazine. during the ship's late 1940–early 1941 anti-aircraft refit, the mainmast was replaced by a platform for a single 37-millimeter twin-gun mount and two of her single 37-millimeter mounts were transferred to the platform while the other two single mounts were removed. the hotchkiss machineguns were repositioned in front of the bridge and a pair of browning 13.2-millimeter aa machine guns were installed on new platforms between the funnels. her aft torpedo mount was removed to compensate for the additional weight. "le chevalier paul" was scheduled to receive a british alpha 128 asdic system, but was sunk before it could be installed.
