After returning to Purvis Bay, Florida Island, on 28 October, "George" resumed anti-submarine patrols and escorted convoys to New Guinea, Manus, Guam, and Saipan. During the liberation of the Philippines, she escorted convoys out of Ulithi, and in February 1945, she escorted ships from Guam to Iwo Jima during the invasion and occupation of that embattled island. In addition, she served as air-sea rescue station, and on 18 April 1945, she rescued three survivors from a B-29 forced to ditch off Iwo Jima.
