USS Clamagore (SS-343) was a Balao-class submarine of the United States Navy, built in 1945 and still in training when World War II ended. She was named for the clamagore or blue parrotfish, Scarus coeruleus, found in the West Indies and along the Atlantic coast as far north as Maryland.

Clamagore was built by Electric Boat Co. in Groton, Connecticut near the end of World War II. She was launched on 25 February 1945 and commissioned on 28 June 1945, with Commander S.C. Loomis, Jr., taking command.[9]

Clamagore was first assigned to Key West, and reported there on 5 September 1945. She operated off Key West with various fleet units and with the Fleet Sonar School, voyaging on occasion to Cuba and the Virgin Islands until 5 December 1947, when she entered Philadelphia Naval Shipyard for GUPPY II modernization and installation of snorkel.[9]

Clamagore returned to Key West 6 August 1948 and assumed local and Caribbean operations for the next eight years, except for a tour of duty in the Mediterranean from 3 February to 16 April 1953.[9]

Clamagore called at New London and Newport early in 1957, returning to Key West 13 March. Between 23 September and 7 December she took part in NATO exercises in the North Atlantic, calling at Portsmouth, England, and NS Argentia, Newfoundland. On 29 June 1959, she arrived at Charleston, her new home port, and after a period of coastwise operations, sailed 5 April 1960 to join the 6th Fleet in the Mediterranean for a tour of duty which continued until July, when the submarine returned to Charleston. For the remainder of 1960 Clamagore operated off the east coast.[9]

In 1962, Clamagore became one of only nine boats to undergo the GUPPY III conversion.[10] She had a 15 feet (4.6 m) hull extension added forward of the control room, a plastic sail and the BQG-4 PUFFS passive ranging sonar, which included the three sharkfin sensors on her deck.[5]

Clamagore finished her GUPPY III conversion in February 1963, and was transferred to New London.[citation needed]

Post operational history[edit]

USS Clamagore, 24 November 2003.

Clamagore was decommissioned 12 June 1975 and stricken on 27 June 1975.[1][2] She was donated as a museum ship on 6 August 1979.[citation needed]

Clamagore arrived at Patriot's Point Naval & Maritime Museum, Charleston, South Carolina in May 1981,[11] where she was docked as a museum ship along with aircraft carrier Yorktown and destroyer Laffey. Clamagore is available for visitor tours. Her continually deteriorating condition, however, may lead to the sub being sunk as an artificial reef unless critical repairs can be made in a timely manner.[12]

Clamagore was listed on the National Register of Historic Places and designated a National Historic Landmark on 29 June 1989.[8][7][13]

According to the South Carolina Department of Archives and History, Clamagore "is now the only surviving GUPPY type III submarine in the United States. She represents the continued adaptation and use of war-built diesel submarines by the Navy for the first two decades after the war. The GUPPY conversion submarines comprised the bulk of the nation's submarine forces through the mid-1960s."[14]
