Additionally:
* {{USS|G-2||2}}, decommissioned as a target, flooded and sank unexpectedly 30 July 1919 in Two Tree Channel near [[Niantic, Connecticut]] with the loss of three crew.
* {{USS|S-48||2}} foundered 7 December 1921 in {{convert|80|ft|m|0}} of water on a pre-commissioning dive. She was raised and commissioned 14 October 1922.
* {{USS|R-8||2}}, decommissioned on 2 May 1931, she was berthed at Philadelphia until 26 February 1936 when she sank at her mooring. Later raised, she was struck from the Naval Vessel Register on 12 May 1936 and on 19 August she was used as a target vessel for an aerial bombing test.

==During World War II==
===American submarine losses===
{{Further|Allied submarines in the Pacific War}}
During [[World War II]], the U.S. Navy's submarine service suffered one of the highest casualty percentage of all the American armed forces, losing one in five submariners.<ref>Blair, pp. 877</ref> Some 16,000 submariners served during the war, of whom 375 officers and 3,131 enlisted men were killed, resulting in a total fatality rate of around 22%.<ref name=":0">Blair, p. 877.</ref>

Fifty-two [[submarine]]s of the [[United States Navy]] were lost during [[World War II]], all but one, {{USS|Dorado|SS-248|3}}, were lost in the Pacific theater of operations.<ref>″United States Submarine Losses World War II″, Naval History Division, Office of the Chief of Naval Operations, Washington: 1963 (Fifth Printing)</ref> Two – ''Dorado'' (SS-248) and {{USS|Seawolf|SS-197|3}} – were lost to [[friendly fire]] (though there is speculation that the ''Dorado'' may have struck a German mine), at least three more – [[USS Tullibee (SS-284)|''Tulibee'']], [[USS Tang (SS-306)|''Tang'']], and [[USS Grunion (SS-216)|''Grunion'']] – to defective [[Mark 14 torpedo|torpedoes]], and six to accident or grounding.<ref>Blair, Clay, Jr. ''Silent Victory'' (Philadelphia: Lippincott, 1975), pp. 991–92, {{ISBN|0-553-01050-6}}.</ref>

Another eight submarines went missing while on patrol and are presumed to have been sunk by Japanese mines, as there are no known Japanese anti-submarine attacks in their patrol areas. The other thirty-three lost submarines are known to have been sunk by the Japanese.

===Additional casualties===
There are two additional casualties to submarines in World War II that are sometimes considered as effectively two additional losses.

{{USS|Halibut|SS-232|6}} 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 a [[constructive total loss]] and 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||6}} 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.<ref>Bauer & Roberts, p. 275</ref><ref>Friedman through 1945, p. 297</ref><ref>Silverstone, p. 199</ref> Postwar, she was listed as a [[United States Navy reserve fleets|Reserve Fleet]] submarine until stricken in 1958 and scrapped in 1959, having never gone to sea.

===Additional incidents===
The former {{USS|R-19||6}} was transferred to the [[Royal Navy]] 9 March 1942 and renamed as HMS ''P.514''. On 21 June 1942 she was rammed by the Royal Canadian Navy minesweeper {{HMCS|Georgian}} and sank with all hands after the submarine was mistaken for a German U-boat.

The former {{USS|S-49||6}} 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||6}} was transferred to the [[Royal Navy]] 4 November 1941 and renamed as 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.

{{USS|R-1||6}}, originally commissioned on 16 December 1918 and decommissioned after more than 12 years of service, was recommissioned and served for five additional years during World War II. ''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 {{convert|21|ft}} of water. Raised three days later, she was sold for scrap on 13 March 1946.

{{USS|S-37||6}} was decommissioned on 6 February 1945, was stripped, and her hulk was supposed to be expended as a target for aerial bombing off San Diego, California, but she broke her tow cable and sank, coming to rest in some {{convert|50|to|60|ft|0}} of water, on 20 February 1945. Her name was stricken from the Naval Vessel Register three days later. Salvagers unsuccessfully tried to retrieve the wreck of ''S-37'' for her scrap value, but lost her again off [[Imperial Beach, California]], in {{convert|20|to|30|ft}} of water at {{coord|32|36.2541|N|117|08.2334|W|name=USS ''S-37''}}, where she remains to this day.

| 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.

===Additional incidents===
{{USS|Tarpon|SS-175|6}} 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.

USS Sargo - SSN-583 was docked in Pearl Harbor on 14 June 1960, preparing to take Bhumibol Adulyadej and his wife Mom Rajawongse Sirikit Kitiyakara, the King and Queen of Thailand on a cruise the next day. Sargo was charging her oxygen tanks when the oxygen line, which entered the submarine through the stern torpedo room hatch, developed a leak and a fire ignited. Two Mark 37 torpedo warheads detonated "low-order", and the fire spread dramatically, killing the crewman tending the oxygen line, machinist's mate third class James E. Smallwood. The fire, fed by the pressurized oxygen, shot flames over 100 feet (30 m) in the air through the hatch. When the combined forces of the shipyard and the boat's crew were unable to control the fire, Sargo's officers took the submarine a short distance from the pier and submerged with the stern room hatch open. The fire was extinguished, and Sargo bottomed in the channel. A floating crane later raised the Sargo, which was towed to Pearl Harbor Naval Shipyard for repairs. Subsequent repairs took three months in drydock. Sargo was returned to active service in October 1960 and remained so until decommissioned and stricken from the Naval Vessel Register on 21 April 1988. James E. Smallwood MM3(SS), who sacrificed his life in the fire while taking action to save the ship was awarded, posthumously, the Navy and Marine Corps Medal for having "firmly and meticulously carried out the ship's safety precautions requiring isolation of the charging compartment from the remainder of the vessel. Aware of the potential danger involved, he kept the watertight door and bulkhead flappers shut." Other crew members were also awarded medals and letters of commendation for outstanding courage over and above the call of duty.

{{USS|Guitarro|SSN-665|6}} 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 aft portions of the submarine. Eventually the lack of coordination led to flooding through the bow hatch.<ref>{{Cite web|url=http://www.history.navy.mil/library/special/guitarro.htm|archive-url=https://web.archive.org/web/20030430180414/http://history.navy.mil/library/special/guitarro.htm|url-status=dead|archive-date=April 30, 2003|title=Report of the Armed Services Investigating Subcommittee on the sinking of ''Guitarro'', 30 June 1969}}</ref> The submarine was raised, but completion was delayed 32 months.

{{USS|Bonefish|SS-582|6}} 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|6}} 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]].<ref>{{Cite web|url=https://www.navy.mil/Resources/Blogs/|archive-url=https://web.archive.org/web/20200801110337/https://www.navy.mil/Resources/Blogs|url-status=dead|archive-date=August 1, 2020|title=Blogs|website=www.navy.mil}}</ref><ref>McDermott, Jennifer, "[http://www.stripes.com/news/us/fire-stricken-submarine-uss-miami-is-decommissioned-1.275179#.UziilcKRVZI Fire-stricken submarine USS Miami is decommissioned]", ''[[The Day (New London)|The Day]]'', 29 March 2014; reprinted in ''[[Stars and Stripes (newspaper)|Stars and Stripes]]''</ref>
