Her personnel went ashore daily to clear debris from the hangars and the surrounding area in order to make the base operable, thereby relieving the congestion at aircraft tenders.

When Shelikof departed on 3 December 1944, Naval Air Base Saipan, was being used as a supply depot and a major overhaul facility.

Shelikof spent the next three months shuttling spare parts and supplies between Guam, Ulithi Atoll, and Saipan.

The seaplane base was shifted to Chimu Wan, Okinawa, on 15 July 1945 and Shelikof operated there until the end of hostilities with Japan on 15 August 1945, which brought World War II to a close.

After the end of the war, Shelikof shuttled between Okinawa and ports in Japan until departing for the United States on 25 October 1945.

En route she made port at Midway Atoll; Pearl Harbor; San Diego; Acapulco, Mexico; and Coco Solo, Panama Canal Zone, before arriving at Norfolk, Virginia, on 4 December 1945.
