USS Albacore (AGSS-569) was a unique research submarine that pioneered the teardrop hull form (sometimes referred to as an “Albacore hull”) of modern submarines. It was the third ship of the United States Navy to be named for the albacore, a small tuna found in temperate seas throughout the world.
After frequent diesel engine failures had caused repeated delays in her operations, her deployment in support of Project SURPASS was canceled and preparations for her deactivation were begun. Albacore was decommissioned on December 9, 1972 and laid up at Philadelphia, Pennsylvania. Her name was struck from the Naval Vessel Register on May 1, 1980, and she was towed back to Portsmouth late in April 1984. When being towed to her drydock, the Albacore became stuck in the mud of Portsmouth Harbor. In 1985, she was dedicated as a memorial.
