In 1976 , ex - " Menhaden " was towed from California to Washington to begin a new career as the " Yellow Submarine . " The boat , stripped of her engines and painted yellow , was operated by the Naval Undersea Warfare Engineering Station in Keyport , Wash . Affectionately referred to as " The Hulk " , she served as a remotely controlled , unmanned acoustic test vehicle capable of submerging to moderate depths in support of undersea weapons testing , and as a target ship to train Trident missile submarine crews off the coast of Washington . In 1988 she sank , due to a leaking main - ballast - tank vent - valve when she was being cut up for scrap . As the tide came in , she was not able to float fast enough to avoid being flooded through all of the holes cut through her pressure hull . The city of Everett eventually finished scrapping the abandoned hulk .
