Returning to Guam on 15 April, the "beef boat" then sailed for the United States. A severe tropical storm enlivened her passage home before she arrived at San Francisco on 12 May. Sailing for the west again on 2 July, "Arctic" arrived at Ulithi on the 26th before she proceeded, in convoy UOK-43, for Okinawa, where — from 5–21 August — she issued fresh, frozen and dry provisions to fleet units. After Japan capitulated, she returned to Pearl Harbor on 11 September for repairs and reloading, before sailing for Japanese waters on 24 October. While "en route" to Tokyo, she sank a mine with gunfire on 12 November.
