For the remainder of World War II, "Tallulah" operated from the base at Ulithi in support of the invasion forces at Okinawa and of the Fast Carrier Task Force during its strikes against Japan and her outposts in China and Southeast Asia. She returned to Ulithi periodically for upkeep and to take on fresh supplies of oil. Then with her tanks full, she carried her precious cargo to the fighting forces. In addition to Ulithi, she visited the base at Leyte Gulf, the forward base at Kerama Retto — located just to the west of Okinawa — and Buckner Bay at the island itself.
