Throughout early September, "Rudyerd Bay" served as a replenishment carrier, providing replacement aircraft (from VC-77), parts, and supplies for the frontline Fast Carrier Task Force of the Third Fleet, which at the time was supporting the Mariana and Palau Islands campaign. Later, during October, she continued supporting the fast carriers as they operated in support of the Philippines campaign. "Rudyerd Bay" was still a part of Task Group 30.8, now renamed the At Sea Logistics Group. The fleet oilers had been detached, and the number of escort carriers involved had increased to eleven. On 18 October, the carrier took on the wounded of the light cruiser , which had been subjected to two separate aerial torpedo hits. She transported them to Ulithi in the Caroline Islands, and by November, the carrier was back to replenishment duties, which would eventually take her into Typhoon Cobra.
