USS S - 48 ( SS - 159 ) foundered 7 December 1921 in 80 feet of water on a pre-commissioning dive. She was raised and commissioned 14 October 1922. During World War II During World War II, the U.S. Navy 's submarine service suffered the highest casualty percentage of all the American armed forces, losing one in five submariners. Some 16,000 submariners served during the war, of whom 375 officers and 3131 enlisted men were killed. Fifty - two submarines of the United States Navy were lost during World War II. Two -- Dorado ( SS - 248 ) and Seawolf ( SS - 197 ) -- were lost to friendly fire ( with S - 26 ( SS - 131 ) probably additional friendly fire, as the collision with USS Sturdy ( PC - 460 ) appears due to being mistaken for a U-boat ), at least two more -- Tulibee and Tang -- to defective torpedoes, and six to accident or grounding. Another eight submarines went missing while on patrol and are presumed to have been sunk by Japanese mines, as there were no recorded Japanese anti-submarine attacks in their patrol areas. The other thirty - three lost submarines are known to have been sunk by the Japanese.

USS Halibut ( SS - 232 ) was damaged by Japanese air and surface forces on 14 November 1944. She was able to reach Saipan and later Pearl Harbor on 1 December, departing San Francisco for Portsmouth Navy Yard on 16 February 1945. There it was determined that she was beyond economical repair, but might be useful as a school ship, similar to the postwar immobile pierside training submarines. However, her career in this capacity was brief, and Halibut was decommissioned at Portsmouth Navy Yard 18 July 1945 and sold for scrap in January 1947. USS Lancetfish ( SS - 296 ) was commissioned on 12 February 1945 and sank at pier 8 at the Boston Navy Yard on 15 March 1945, apparently without loss of life and reportedly still incomplete. She was raised eight days later, decommissioned on 24 March 1945, and never completed or fully repaired. Postwar, she was listed as a Reserve Fleet submarine until stricken in 1958 and scrapped in 1959, having never gone to sea. Additional incidents The former USS R - 19 ( SS - 96 ) was transferred to the Royal Navy 9 March 1942 and renamed as the RMS P. 514. On 21 June 1942 she was rammed by the Royal Canadian Navy minesweeper HMCS Georgian and sank with all hands. The former USS S - 49 ( SS - 160 ) was sold in 1931 to a private owner for use as a tourist attraction, with the hulk reacquired by the U.S. Navy for `` experimental purposes '' in 1941. She foundered and sank in the Patuxent River 16 December 1942. The former USS S - 25 ( SS - 130 ) was transferred to the Royal Navy 4 November 1941 and renamed as the RMS P. 551 then transferred to the Polish Navy in exile and renamed ORP Jastrząb. On 2 May 1942 she was attacked in a friendly fire incident by a Royal Navy minesweeper and destroyer and sank with all hands. The USS R - 1 ( SS - 78 ), originally commissioned on 16 December 1918 and decommissioned after more than 12 years of service, was recommissioned and served for five additional years during WWII. R - 1 was decommissioned at Key West on 20 September 1945 and was struck from the Naval Vessel Register on 10 November. Still at Key West awaiting disposal on 21 February 1946, the submarine sank in 21 feet ( 6.4 m ) of water. Raised three days later, she was sold for scrap on 13 March 1946 State adoptions The United States Submarine Veterans of World War II have suggested each of the fifty states of the United States `` adopt '' one submarine, except California and New York, which should adopt two.

Lost between 22 May and 5 June 1968 Cause unknown ; numerous theories have been advanced. Recent deep submergence photography indicates the possibility of an implosion event not unlike the USS Thresher. North Atlantic Ocean, 400 nautical miles ( 740 km ) southwest of the Azores Stickleback SS - 415 000000001958 - 05 - 20 - 0000 20 May 1958 Collision with USS Silverstein ( DE-534 ) Oahu, Hawaii Thresher SSN - 593 000000001963 - 04 - 10 - 0000 10 April 1963 Exact cause unknown ; one theory is a seawater leak led to a reactor plant shutdown, compounded by a heavy trim ( excess negative buoyancy ) and an inadequate ballast tank blow system. Another theory is that a reactor plant scram occurred for tests ; a flaw caused an inability to operate key reactor valves and other valves, which prevented emergency surfacing. Or, a problem in the procedures for a scram caused the inability to operate a very important steam plant valve, causing a loss of propulsion. Any of these problems could have caused the boat to sink beyond crush depth. 200 nautical miles ( 370 km ) east of Cape Cod, Massachusetts Additional incidents The USS Tarpon ( SS - 175 ) Was decommissioned on 15 November 1945 and sold for scrap 8 June 1957. The Tarpon foundered in deep water, south of Cape Hatteras, North Carolina, on 26 August 1957, while under tow to the scrap yard. The USS Guitarro ( SSN - 665 ) flooded and sank pier - side prior to commissioning at Mare Island Naval Shipyard on 15 May 1969. Two shipyard teams, apparently unaware of each other 's efforts, were conducting work involving filling tanks in both the forward and after portions of the submarine. Eventually the lack of coordination led to flooding through the bow hatch. The submarine was raised, but completion was delayed 32 months. Guitarro was commissioned on 9 September 1972. USS Bugara ( SS - 331 ) was decommissioned and struck from the Naval Register 1 October 1970. On 1 June 1971, while under tow near Cape Flattery, Washington state, Bugara swamped and sank accidentally. USS Bonefish ( SS - 582 ) was not repaired after a fire near Florida on 24 April 1988 that killed three crewmembers. She was decommissioned 28 September 1988 and hulked 17 August 1989. The hull was later purchased by Northrop Grumman for testing. USS Miami ( SSN - 755 ) experienced a fire during overhaul at Portsmouth Naval Shipyard on 23 May 2012 that caused significant damage, though with no loss of life. A civilian shipyard worker confessed to arson. Although repairs were considered, using components from the decommissioned USS Memphis ( SSN - 691 ), the estimated cost of $700 million was considered uneconomical in a time of reduced budgets. Miami was decommissioned on 28 March 2014, to be disposed of via the nuclear Ship - Submarine Recycling Program.
