carried six Modèle 1909R torpedoes. They had a warhead and two speed/range settings: at or at . The Dantons also had storage space for 10 Harlé Modèle 1906 mines, which had an explosive charge of of guncotton. These could not be laid by the ships themselves, but had to be off-loaded for use. Fire control Finding the British Barr & Stroud coincidence rangefinder design superior to existing French designs, the Dantons mounted a pair of FQ rangefinders atop the conning tower and a rangefinder on each turret top for use by the turret commanders. Integrating these into the overall fire-control system took some time, so eight Ponthus & Therrode stadimeters, which required knowledge of the target's mast height and overall length, were used in the interim. During the war, the rangefinders were replaced by longer, more precise instruments. A triple model was installed above the conning tower and 2-meter models replaced the smaller ones on the turret roofs. Armor The Danton-class ships were built with of armor, 36 percent of their designed displacement and almost more than their predecessors. Their waterline armored belt had a maximum thickness of between the fore and aft turrets that reduced to towards the bow and stern. The belt consisted of two strakes of armor, high, that covered the sides of the hull up to the main deck and extended below the normal waterline. Most of the lower armor plates tapered to a thickness of along their bottom edge and the upper plates tapered to amidships and down to at the ends of the ship. The belt armour was backed by of teak. It extended almost the entire length of the ship, with only the very stern unprotected. At the stern, the belt terminated in a transverse bulkhead; the forward transverse bulkhead connected the sides of the forward barbette to the belt. The main gun turrets had of armor on their faces, sides, and roofs of three layers of mild-steel plates. Their barbettes were protected by of armor which thinned to below the upper protected deck. The secondary gun turrets had faces, sides, and a roof of three layers of plates. The 240-millimeter turret barbettes had sides . The front of the conning tower had armor thick and its sides were . The walls of its communication tube down to the fire-control center (poste central de tir) were 200 millimeters thick down to the upper
