"Africa" had a main battery of four 40-calibre guns mounted in twin-gun turrets fore and aft. These were supported by a heavy secondary battery of four guns in four single turrets, two on each broadside. The ships also mounted ten 6-inch 50 calibre guns mounted in casemates, in addition to fourteen 12-pounder guns and fourteen 3-pounder guns for defence against torpedo boats. As was customary for battleships of the period, she was also equipped with five torpedo tubes submerged in the hull; two were on each broadside, with the fifth in the stern.
