The ship was armed with four 32-calibre BL 13.5-inch Mk I–IV guns in two twin gun turrets, one fore and aft of the superstructure. Each gun was provided with 80 shells. "Hood"s secondary armament consisted of ten 40-calibre 6-inch Mk I-III guns mounted in casemates in the superstructure. A major problem with the four of these guns mounted on the upper deck was that they were mounted low in the ship and were unusable at high speed or in heavy weather. They were removed in 1904. The ship carried 200 rounds for each gun.
