== Operational submarines ==

As of 2007 {{USS|Tusk|SS-426|2}}, a ''Balao''-class submarine, was one of the last two operational submarines in the world built during World War II. The boat was transferred to [[Taiwan]]'s [[Republic of China Navy]] in the early 1970s. The ''Tench''-class ex-{{USS|Cutlass|SS-478|2}} is the other one. They are named ''Hai Pao'' and ''Hai Shih'', respectively, in Taiwanese service.<ref>[http://www.maritime.org/taiwan/index.htm Museum documents an operating US, WW II built submarine in Taiwan]</ref><ref>{{cite news|publisher=Taipei Times|title=World's longest-serving sub feted|author=Jimmy Chuang|date=17 Apr 2007|page=2|url=http://www.taipeitimes.com/News/taiwan/archives/2007/04/17/2003356990}}</ref>
