After shakedown, Sausalito arrived at Adak, Alaska, on 5 October 1944 for convoy escort duty in the Alaskan Sea Frontier. She performed these duties until departing on 5 June 1945 for overhaul at Seattle. On 16 August 1945, she was decommissioned at Cold Harbor, Alaska, and transferred to the Soviet Union under Lend Lease as EK-13.
The ship was returned to United States custody by the Soviet Union on 1 November 1949 and was placed in reserve in Japan. With the outbreak of the Korean War, additional escort vessels were needed ; and, on 15 September 1950, Sausalito was recommissioned at Yokosuka, Japan, Lt. Comdr. Francis W. Deily in command. On 26 November, she departed Yokosuka for Hungnam, North Korea. There, until 24 December 1950, she performed harbor control duties which included escorting ships through the mineswept channel, passing instructions to ships entering the harbor, patrolling the entrance against hostile craft and drifting mines, and conducting shore bombardment when required. Between February and May 1951, her assignments included escorting battleship, Missouri (BB-63), on her shore bombardment station, blockade patrols and shore bombardment on the east coast of North Korea from Wonsan to Chongi in, and harbor control duty at Wonsan, broken by periods of upkeep at Sasebo and Yokosuka, During the period from June to August, she escorted underway replenishment groups off the Korean coast.
After drydocking and upkeep at Yokosuka, Sausalito sailed for the Philippines in October. In late November and early December, she conducted a patrol against unauthorized fishing vessels in the Sonsorol Islands in the Western Carolines, apprehending one vessel. After Christmas in Subic Bay, she made a good-will tour to Saigon, Bangkok, Singapore, and Penang. February found her back in Korean waters, where she resumed escort and patrol duties before returning to Yokosuka for the last time under the United States flag on 31 May. On 9 June 1952, Sausalito was decommissioned and on 4 September was transferred, on loan, to the Republic of Korea as Imchin (PF-66).
