USS Oak Ridge (ARD-19/ARDM-1), was an ARD-12-class floating dry dock suitable for docking destroyers, submarines and landing craft. Self-propelled but unable to cross the ocean under her own power, she was towed, in stages across the Pacific. While in transit she was used as a van to help move the service squadron forward and at the end of August 1944 arrived at Seeadler Harbor carrying a YTL, 2 pontoon crane barges, and 20 LCMs and LCVPs. From Manus ServRon 10 provided the logistic support for the Palau offensive, then moved itself forward to Ulithi and Kossol Roads. The Leyte landings soon followed and the repair facilities were moved up to San Pedro Bay.
