She took part in fleet problems and exercises on the west coast, in Hawaiian and Caribbean waters; operated with Aircraft, Battle Force; conducted practice cruises to Canadian and Alaskan ports for members of the Naval Reserve; and spent from 15 July to 17 December 1934 in the Rotating Reserve.

Chelsea reached Devonport, England, 28 September 1940. Assigned to the Sixth Escort Group, Western Approaches Command, Liverpool, for Atlantic convoy duty, she fought the double-menace submarine and air attacks on vital supplies. On 6 April 1941 she rescued 29 survivors of SS Olga S. which had been sunk by an air attack.[1]Chelsea was modified for trade convoy escort service by removal of three of the original 4"/50 caliber guns and one of the triple torpedo tube mounts to reduce topside weight for additional depth charge stowage and installation of hedgehog.[2]
Chelsea joined Arbutus on 5 February 1942 to hunt for a submarine sighted from their convoy. Two hours later Arbutus was torpedoed. Chelsea opened fire on the surfaced submarine and made three depth charge attacks after she dived but contact was lost and she returned to pick up the survivors from Arbutus.[1]
In November 1942 Chelsea was lent to the Royal Canadian Navy and until the end of 1943 operated in the mid and western Atlantic Ocean escorting convoys to and from Great Britain. She returned to Derry, Northern Ireland, 26 December 1943 and early in 1944 was reduced to reserve on the Tyne. On 16 July 1944 she was transferred to Russia and renamed Derzky[1] (rus. Дерзкий, "Insolent").[note 2]
