From 21 November-13 December, "Arctic" provisioned fleet units off Yokosuka before she returned to Hawaiian waters — again sinking a mine "en route" — on 20 December. She departed Pearl Harbor on 2 January 1946 and arrived at San Diego on the 16th, where she remained for a little over a month. She left the west coast of the United States for the last time on 18 February, bound for the Gulf of Mexico. Material defects having rendered continued operation of the venerable "Arctic" "impracticable," the veteran "beef boat" was on her last voyage. Transiting the Panama Canal on 7 March, "Arctic" arrived at New Orleans, Louisiana on the 15th. There, at Pendleton Shipyards, she was decommissioned on 3 April. Her name was struck from the Naval Vessel Register on 1 May. Transferred to the Maritime Commission for disposition on 3 July, the ship was then sold on 19 August 1947 to the Southern Shipwrecking Corp. and met her end under the scrapper's torch.
