a speed of , depending on which boilers were fitted. Their endurance was almost half that of their predecessors due to the uneconomical fuel consumption of their turbines at low speeds and meant that they needed frequent coaling stops during the war. Armament The main battery of the Danton-class ships consisted of four 305 mm Modèle 1906 guns mounted in two twin-gun turrets, one each fore and aft of the superstructure. Each turret could elevate up to +12° that gave the guns a maximum range of . The guns fired armor-piercing projectiles at a muzzle velocity of at a rate of 1.5 rounds per minute. Each turret stored eight rounds along the rear wall and their propellant was kept between the floor of the firing chamber and the bottom of the turret. The ships normally stowed 75 rounds per gun, but space was available for an additional 10 rounds. Their secondary armament consisted of twelve 240mm/50 Modèle 1902 guns in six twin-gun turrets, three on each side of the ship. Maximum elevation of the turrets was +13° and the shell could be fired to a range of . The guns could fire at a rate of two rounds per minute. Each turret had space for 12 shells and the necessary 36 propellant charges; 80 rounds per gun was normally carried, but maximum capacity was 100 rounds per gun. The Dantons carried a number of smaller guns to defend themselves against torpedo boats. These included sixteen Modèle 1908 Schneider guns mounted in unarmored embrasures in the hull sides. These guns had a range of and could fire approximately 15 rounds per minute. Because the shell hoists were slow and the shells difficult to handle in their three-round cases in the magazines, a total of 576 rounds were stored close to the guns in ready-use lockers. Each gun was provided with 400 rounds, but the maximum storage available was 430 rounds per gun. The ships also mounted ten Hotchkiss guns in pivot mounts on the superstructure. They had the same rate of fire as the larger 75 mm guns, but only a range of . Each gun had 36 rounds nearby in ready-use lockers and the ships were provided with a maximum of 800 rounds per gun. The battleships were also armed with two submerged torpedo tubes, one on each broadside. Each tube was angled 10° forward and 3° downward. Each ship
