Her armament consisted of ten 14-inch/45-caliber guns which could be elevated to 15 degrees, and arrayed in five double mounts designated, from bow to stern, 1, 2, 3, 4, and 5. The class was the last to feature a turret mounted amidships. As built, she also carried twenty-one /51-caliber guns, primarily for defense against destroyers and torpedo boats. The 5-inch guns were poor in accuracy in rough seas due to the open casemates mounted in the hull, so the 5-inch armament was reduced to 16 guns in 1918 by removal of the least useful positions near the ends of the ship. The ship was not designed with anti-aircraft (AA) defense in mind, but two /50 caliber AA guns were added in 1918. She also had four torpedo tubes, 1 each on the port side bow and stern and starboard bow and stern, for the Bliss-Leavitt Mark 3 torpedo. The torpedo rooms held 12 torpedoes total, plus 12 naval defense mines. Her crew consisted of 1,042 officers and enlisted men.
