were given a large torpedo battery in consequence. Two triple Modèle 1928T torpedo launchers were fitted on each beam between the funnels and two twin Modèle 1928D launchers were located on the beam, abaft the second funnel. The placement of each launcher on the beam significantly increased each launcher's arc of fire (25° to 150°) in comparison to the Le Fantastaques centerline mount (60°-100°). However this was not without cost as her torpedo broadside was weaker by one tube than the older class, but the extra launchers positioned close to the ship's side imposed, more importantly, a weight and stability penalty. All of her mounts used the Modèle 1923DT torpedo with a warhead. This torpedo used a four-cylinder, radial Brotherhood alcohol engine to power it at two set speeds. The fast speed was to a range of while the slow speed setting was to a range of . Twin depth charge tunnels were built into the rear hull of the Mogador-class ships. Each tunnel housed eight Guirard depth charges, with another sixteen stowed in the rear magazine. They were launched by remote control in patterns of four using a chain system. Since no sonar equipment was fitted these depth charges were unlikely to actually damage a submarine. Fixed pairs of mine rails were mounted above the stern and each pair could carry five Bréguet B4 mines. These could be extended using removable section stowed between decks to carry another thirty mines if necessary. Fire control The centralized fire-control system was similar to that of the Le Fantasque-class with 12 × 72 target-designation binoculars on each side of the bridge linked by Granat transmitters to the directors located atop the bridge and abaft the second funnel. Each director had a OPL Modèle 1935 stereoscopic rangefinder and sent the range to the where it was fed into a modernized Modèle 1929 electro-mechanical computer which calculated the firing solution and transmitted it to the turrets. The turrets could also be controlled locally if necessary. The torpedo-control system was much the same, although entirely separate from the gunnery system. 8 × 30 target-designation binoculars were mounted on each side of the bridge and transmitted the target's bearing to the torpedo director located above the primary gunnery director above the bridge. It used a separate 5-metre OPL Modèle 1935 stereoscopic rangefinder to provide the bearing and range to a Modèle 1933 electro-mechanical computer which calculated
