The main armament of the "Hawkins"-class ships consisted of seven Mk VI guns in single mounts protected by gun shields. They were arranged with five guns on the centreline, four of which were in superfiring pairs fore and aft of the superstructure, the fifth gun on the quarterdeck, and the last two as wing guns abreast the aft funnel. Their secondary armament consisted of ten 20 cwt guns. Six of these were in low-angle mounts, two in casemates between the forward 7.5-inch guns, another pair on platforms abreast the conning tower and the remaining guns on a platform between the funnels, although these last two guns were removed in 1921. The last four served as anti-aircraft (AA) guns and were positioned around the base of the mainmast. The rest of their anti-aircraft suite consisted of a pair of 2-pounder () AA guns. The ships were also fitted with six 21-inch (533 mm) torpedo tubes, one submerged and two above water on each broadside.
