had a crew of 44 officers and 1,160 enlisted men when serving as a flagship. Unlike her sister ships, Béarn was intended to be equipped with two sets of Parsons steam turbines, each driving a pair of propeller shafts using steam provided by 28 Niclausse boilers. The engines were rated at and were designed for a speed of , although use of forced draft was intended to increase their output to and the maximum speed to . The ships were designed to carry enough coal and fuel oil to give them an estimated range of at . Armament and armor The main battery of the Normandie class consisted of a dozen Canon de Modèle 1912M guns mounted in three quadruple turrets. One turret was placed forward, one amidships, and one aft of the superstructure, all on the centerline. The ships would also have been equipped with a secondary armament of 24 Canon de Modèle 1910 guns, each singly mounted in casemates near the main-gun turrets. Anti-aircraft defense probably would have been provided by four Canon de Modèle 1902 AA guns. The ships also would have been equipped with six underwater torpedo tubes, three on each broadside. The waterline armor belt of the Normandie-class ships extended almost the entire length of the hull, save for at the stern. The thickest portion of the armor protected the hull between the barbettes of the end turrets and was thick. From the forward barbette to the bow, the plates progressively reduced in thickness from , aft of the rear turret, the armor plates were progressively reduced in thickness from 260 millimeters to . The turrets were protected with an armor thickness of 300 millimeters on their faces, on the sides, and 100 millimeters on the roof. The casemates were defended by 160-millimeter armor plates. The portions of the barbettes that extended outside the upper armor were protected by plates. The sides of the conning tower were thick and its roof was also 100 millimeters thick. The lower armored deck ranged in thickness from with the thickest portion of the deck where it sloped to meet the bottom of the armor belt. The upper armored deck was thick with the thickest part on the outer edges. The torpedo bulkhead of the Normandies consisted of a nickel-steel plate, faced with a plate of corrugated mild steel that was intended to absorb the shock wave from a
