USS Oak Ridge (ARD-19/ARDM-1) was originally a United States Navy Auxiliary floating drydock suitable for dry docking destroyers, submarines and landing craft, built by the Pacific Bridge Company.

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.

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 support forward deployed Fleet Ballistic Missile (FBM) submarines.

With USS Mahoa (YTM-519) in her dock basin, she arrived at Rota 22 days later and commenced providing the services, to Polaris-equipped submarines and others as required attached to SUBRON 16 until June 1979.

Oak Ridge was decommissioned on 10 August 2001, stricken from the Naval register on 26 November 2001, and transferred to the United States Coast Guard on 8 February 2002; categorized as a moveable piece of docking equipment and recorded as General Purpose Property.
