Service history.
U.S. Navy, World War II, 1944–1945.
After shakedown, "Sausalito" arrived at Adak, Territory of Alaska, on 5 October 1944 for convoy escort duty in the Alaskan Sea Frontier. She performed these duties until – having been selected for transfer to the Soviet Navy in Project Hula, a secret program for the transfer of US Navy ships to the Soviet Navy at Cold Bay, Alaska, in anticipation of the Soviet Union joining the war against Japan – she departed on 5 June 1945, for overhaul at Seattle, Washington, to prepare her for transfer. She then proceeded to Cold Bay and began training her new Soviet crew.
Soviet Navy, 1945–1949.
Following the completion of training for her Soviet crew, "Sausalito" was decommissioned on 16 August 1945, at Cold Bay, and transferred to the Soviet Union, under Lend-Lease immediately along with her sister ships , , , , and . Commissioned into the Soviet Navy immediately, "Sausalito" was designated as a "storozhevoi korabl" ("escort ship") and renamed EK-16 in Soviet service. She soon departed Cold Bay, bound for Petropavlovsk-Kamchatsky, in the Soviet Union, and served as a patrol vessel in the Soviet Far East.
In February 1946, the United States began negotiations for the return of ships loaned to the Soviet Union for use during World War II. On 8 May 1947, United States Secretary of the Navy James V. Forrestal informed the United States Department of State that the United States Department of the Navy wanted 480 of the 585 combatant ships it had transferred to the Soviet Union for World War II use returned, "EK-16" among them. Negotiations for the return of the ships were protracted, but on 1 November 1949 the Soviet Union finally returned "EK-16" to the US Navy at Yokosuka, Japan.
U.S. Navy, Korean War, 1950–1952.
Reverting to her original name, "Sausalito" was placed in reserve at Yokosuka. With the outbreak of the Korean War on 25 June 1950, the U.S. Navy needed additional escort vessels, and on 15 September 1950, "Sausalito" was recommissioned at Yokosuka. On 26 November 1950, she departed Yokosuka for Hŭngnam, 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 naval mines, and conducting shore bombardment when required.
Between February and May 1951, "Sausalito"s assignments included escorting the battleship on her shore bombardment station, blockade patrols, shore bombardment on the east coast of North Korea from Wonsan to Chongjin, and harbor control duty at Wonsan, broken by periods of upkeep at Sasebo and Yokosuka, Japan. Between June and August 1951, she escorted underway replenishment groups off the Korean coast.
After drydocking and upkeep at Yokosuka, "Sausalito" departed for the Philippine Islands, in October 1951. In late November and early December 1951, she conducted a patrol against unauthorized fishing vessels in the Sonsorol Islands, in the western Caroline Islands, apprehending one vessel. After spending Christmas 1951, in Subic Bay, on Luzon, she made a good-will tour to Saigon, South Vietnam; Bangkok, Thailand; Singapore; and Penang, Federation of Malaya. February 1952, 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 1952. The US Navy decommissioned "Sausalito" on 9 June 1952.

On 4 September 1952, the United States transferred the ship, on loan, to the Republic of Korea for service in the Republic of Korea Navy as ROKS "Imchin" (PF-66). She replaced another "Tacoma"-class patrol frigate, the South Korean ship ROKS "Apnok", ex-, which had been irreparably damaged in a collision on 21 May 1951.
