USS Oak Ridge ( ARDM - 1 ) USS " Oak Ridge " ( ARD - 19 / ARDM - 1 ) , was an 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 .

The Leyte landings soon followed and the repair facilities were moved up to San Pedro Bay . On 27 November ARD - 19 was moored in that bay with USS " Ross " ( DD - 563 ) in dock undergoing repairs . Shortly before noon the Japan ese launched an air attack . A " Tojo " fighter crashed into the drydock , passed through the starboard wingwall of the dock , and caused gasoline fed flames to encompass the dock basin deck , searing " Ross " as they spread . As the fire was being contained another Japanese fighter commenced a strafing run , but was splashed by gunfire from the ARD , " Ross " , and . Heavy damage kept the ARD busy on self - repairs for only a brief time . She soon resumed her drydocking and repair role , and continued that service , at Subic Bay , Luzon , until after the end of World War II .

In March 1949 she carried YFN – 599 to Puget Sound , took on cranes and got underway , in tow , for the Panama Canal Zone . From the Canal Zone she continued on to Orange , Texas , with more district craft in her dock basin . Arriving 10 June , she continued her ferry service until decommissioned and assigned to the Texas Group , Atlantic Reserve Fleet for berthing , 30 September 1949 . Thirteen years later , September 1962 , " ARD - 19 " was brought out of reserve and taken to Jacksonville , Florida , where she was converted , by the Gibbs Shipyards to a fleet Los Angeles - class " fast attack " submarine drydock . Her length increased to 536 ’ 1 ” and her displacement to 9 , 700 tons , she became the first mobile single unit capable of such docking . She was then named , redesignated , and recommissioned as " Oak Ridge ( ARDM - 1 ) " , 1 October 1963 . Further changes , such as the replacement of two 10 - ton cranes with two 25 - ton cranes , kept her at Norfolk until 4 June 1964 when she was taken under tow by Atakapa to begin the long journey to her homeport of Rota , Spain . With in her dock basin , she arrived at Rota 22 days later and commenced providing the services , to Polaris - equipped submarines and others as required , which she continued into 1970 .
