USS Oak Ridge (ARDM-1)

• Unique Vessel Type: USS Oak Ridge (ARDM-1) is a Medium Auxiliary Repair Dry Dock, a floating dry dock designed to provide repair and maintenance services to submarines and smaller naval vessels. • First of Its Class: Oak Ridge was the lead ship of her class and the first ARDM built specifically for the U.S. Navy, commissioned in 1963. • Named After a City: The dry dock is named after Oak Ridge, Tennessee, a city known for its role in the Manhattan Project during World War II. • Homeport in Connecticut: For much of her service life, Oak Ridge was homeported at the Naval Submarine Base New London, Groton, Connecticut, supporting Atlantic fleet submarines. • Support During the Cold War: Oak Ridge played a crucial role in keeping the U.S. submarine fleet operational during the height of the Cold War, providing vital maintenance and repairs. • Versatile Capabilities: The dry dock could lift and service both diesel-electric and nuclear-powered submarines, including the Los Angeles-class attack submarines. • Named Crew Spaces: Unlike warships, Oak Ridge’s crew included both Navy personnel and civilian shipyard workers, reflecting her unique mission and operational requirements. • Deactivation and Reactivation: Oak Ridge was placed out of service in 2001 but was reactivated in 2002 to continue supporting submarine maintenance needs. • International Service: In 2023, Oak Ridge was transferred to the Philippine Navy as BRP Nestor Acero (ARDM-1), marking a new chapter in her service life. • Longevity and Legacy: Having served for over 60 years under two flags, Oak Ridge exemplifies the durability and adaptability of naval auxiliary vessels, with a legacy of supporting submarine readiness across generations.
