Returning to Pearl Harbor or San Francisco to refill her holds with needed supplies, Boreas provisioned many of the major islands and bases in the Pacific including Samoa; Funafuti; Kwajalein; Eniwetok; Tulagi; Guadalcanal; Guam; Saipan; Iwo Jima; Okinawa; Manus; Ulithi; Efate; Tarawa; Makin; Christmas Island; and Auckland, New Zealand. Boreas generally steamed alone, only occasionally rating a small escort, but the store ship never suffered damage and rarely even saw an enemy. Late in 1944, she salvaged cargo from , a concrete storage barge that had grounded on a coral reef off Saipan during a severe storm. The average load of the USS Boreas was valued at $917,280, with a maximum individual load value of $1,077,961 and a minimum individual load value of $688,001. The value of the Boreas cargo of fresh, frozen and dry stores for the entire period amounted to the sum total of $25,028,288. A further breakdown of cargo delivered reveals the following: Auckland and New Zealand were the principal loading ports for the USS Boreas during the latter part of 1944 and 1945. It was because of this that the Boreas achieved the distinction of being the special friend of small craft and the "splinter fleet" at all bases. The ship's store would purchase from three to five thousand gallons of ice cream at each loading which was sold only to small craft for the low price of three dollars and seventy-five cents per tub of five imperial gallons. During the Okinawan campaign, the Boreas was consistently under the protection of the harbor smoke boats. The souvenir craze was as popular on the USS Boreas as it was with any other group of Americans. On the final voyage to Japan, each officer and crewman received at least a Japanese rifle, bayonet and signal pistol as a war trophy. Post-war career After the Japanese agreed to surrender on 15 August 1945, Boreas carried supplies to Okinawa to support occupation forces there. Later in the fall of 1945, she received orders to move on to Japan and provisioned Wakayama, Nagoya, Sasebo, and Kure from 20 October to 18 November when orders came sending her home. Boreas arrived at San Diego on 23 December. The store ship steamed via the Panama Canal for the Norfolk Navy Yard, where she arrived on 19 January 1946. Boreas was decommissioned on 15 February, and her name was struck from the Naval Vessel
