Editing Balao-class submarine (section)

==Postwar service history==

Postwar, 55 ''Balao''s were modernized under the Fleet Snorkel and Greater Underwater Propulsion Power ([[GUPPY]]) programs, with some continuing in US service into the early 1970s. The last ''Balao''-class submarine in United States service was {{USS|Clamagore|SS-343}}, which was decommissioned in June 1975.<ref name="guppysubmarinetribute.homestead.com">[https://web.archive.org/web/20000819012150/http://guppysubmarinetribute.homestead.com/Tribute.html GUPPY and other diesel boat conversions page]</ref> Seven were converted to roles as diverse as guided-missile submarines (SSG) and amphibious transport submarines (SSP). 46 were transferred to foreign navies for years of additional service, some into the 1990s, and {{USS|Tusk|SS-426|2}} remains active in [[Taiwan]]'s [[Republic of China Navy]] as ''Hai Pao''.

===Naval Reserve trainer===

Interested in maintaining a ready pool of trained [[United States Navy Reserve|reservists]], the Navy assigned at least 58 submarines from 1946 to 1971 to various coastal and inland ports (even in [[Great Lakes]] ports like [[Cleveland]], [[Chicago]], and [[Detroit]]), where they served as training platforms during the Reservists' weekend drills. At least 20 ''Balao''-class boats served in this capacity. In this role, the boats were rendered incapable of diving and had their propellers removed. They were used strictly as pierside trainers. These were in commission but classed as "in service in reserve", thus some were decommissioned and recommissioned on the same day to reflect the change in status.<ref>Friedman 1995, p. 285</ref><ref>[http://www.submarinesailor.com/Boats/Reserve/Reserve.asp Reserve Training Boats at SubmarineSailor.com]</ref><ref name="Friedman since 1945, pp. 228-231">Friedman since 1945, pp. 228-231</ref>

===Foreign service===

The large numbers of relatively modern, but surplus U.S. fleet submarines proved to be popular in sales, loans, or leases to allied foreign navies. 46 ''Balao''-class submarines were transferred to foreign navies, some shortly after World War II, others after serving nearly 30 years in the US Navy. These included 17 to Turkey, 2 to Greece, 3 to Italy, 2 to the Netherlands, 5 to Spain, 2 to Venezuela, 4 to Argentina, 5 to Brazil, 2 to Chile, 2 to Peru, 1 to Canada and 1 to Taiwan.<ref name="Friedman since 1945, pp. 228-231"/> One of the Venezuelan boats, ''ARV Carite'' (S-11) formerly [[USS Tilefish (SS-307)|USS ''Tilefish'']] (SS-307), featured in the 1971 film ''[[Murphy's War]]'' with some cosmetic modification.
