aircraft carrier and
destroyer .
Clamagore was listed on the
National Register of Historic Places and designated a
National Historic Landmark on 29 June 1989. According to the South Carolina Department of Archives and History,
Clamagore was the last surviving GUPPY type III submarine in the United States. The GUPPY conversion submarines constituted the bulk of the nation's submarine force through the mid-1960s. Due to severe degradation of the hull the Patriot Point museum had, on several occasions, looked for an alternate means to preserve the vessel. On 10 January 2017 the Palm Beach County Commissioners voted unanimously to approve funds for the vessel to be sunk as an artificial reef. On 16 April 2019 a group of retired submariners sued the State of South Carolina to save the
Clamagore. In early 2020, the museum formed a plan to sink
Clamagore at the Vermilion Reef site before the 2021 hurricane season. During the summer of 2022, the museum began the process of scrapping the
Clamagore. Her National Historic Landmark designation was withdrawn in September 2024. File:USSClamagore112403.jpg|USS
