The main armament of the "Bristol" class was two BL 6-inch (152 mm) Mk XI guns that were mounted on the centreline fore and aft of the superstructure and ten BL 4-inch Mk VII guns in waist mountings. All these guns were fitted with gun shields. Four Vickers 3-pounder (47 mm) saluting guns were fitted, while two submerged 18-inch (450 mm) torpedo tubes were fitted. This armament was considered rather too light for ships of this size, while the waist guns were subject to immersion in a high sea, making them difficult to work.
