In 1941, one of the 4.7 in guns and the aft bank of torpedo tubes was removed, with a anti-aircraft gun replacing the torpedo tubes and an enhanced anti-submarine armament, which included 70 depth charges and the ability to drop patterns of 10 charges. Radar was also fitted, and the destroyer's close-in anti-aircraft outfit was supplemented by the addition of Oerlikon 20 mm cannons, of which two were fitted in 1941 followed by four more later on. The 3 inch gun was removed by 1943, when high-frequency direction finding gear was fitted. A second 4.7 in gun was replaced in 1944 by two QF 6-pounder Hotchkiss guns.
