The USS Hunley (AS-31) was a submarine tender launched on September 28, 1961, and commissioned on June 16, 1962. Built by Newport News Shipbuilding & Dry Dock Company in Virginia, she was specifically designed from the keel up to support and service the U.S. Navy’s nuclear-powered Polaris ballistic missile submarines. Her hull featured complete facilities for maintaining the complex Polaris weapons systems and performing various submarine repairs, excluding major overhaul work typically done at shipyards. The vessel measured with a robust construction tailored for her strategic role. She was distinguished by her capability to handle the Polaris missile system, with modifications made to support the new A3 Polaris missile, ensuring her operational relevance throughout her service life. Her service began with shakedown training off Cuba and included visits to Gulf and Atlantic ports, before heading to Holy Loch, Scotland, in January 1963 to relieve USS Proteus as the tenders’ primary support for the Polaris fleet. Throughout her operational career, Hunley played a critical role in the maintenance and readiness of the U.S. Navy’s SSBN fleet, performing routine refits, repairs, and upgrades. Notably, she reached a milestone in December 1965 by conducting her 100th refit of a nuclear ballistic submarine, reflecting her vital role in maintaining strategic deterrence over 16.5 years of continuous Polaris patrols. Her work included welding on pressure hulls, reactor fluid systems, and installing safety enhancements, exemplifying her technical versatility. Her service included deployments to Holy Loch, Guam, Charleston, and Bremerton, with periods spent in shipyard overhauls and conversions, such as the 1973 overhaul at Bremerton. She was decommissioned on September 30, 1994, and struck from the Naval Vessel Register in 1995. After her decommissioning, she was transferred to the Maritime Commission and ultimately sold for scrap in 2007. The USS Hunley’s contribution was significant in supporting the United States’ strategic missile submarine fleet, ensuring their operational readiness and technological advancement during the Cold War era.
