As completed, the ship's armament consisted of eleven BL 6-inch Mk VII naval guns, nine QF 12-pounder 12 cwt naval guns, six 3-pounder guns, three machine guns, and two 18-inch (450-mm) torpedo tubes mounted broadside. By the 1920s, the 6-inch and 12-pounder guns had been reduced to three and four respectively, although a 12-pounder field gun was added to the ship's arsenal. A single QF 3-pounder Hotchkiss gun replaced the six 3-pounders, while the original three machine guns were supplanted by four Maxim guns and two Lewis guns.
