USS ''Topeka'' (SSN-754), a , was the third ship of the United States Navy to be named for Topeka, Kansas. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 28 November 1983 and her keel was laid down on 13 May 1986. She was launched on 23 January 1988, sponsored by Elizabeth Dole, and commissioned on 21 October 1989, with Commander Timothy Reichert in command.〔("Elizabeth Dole refers to sponsoring USS Topeka in a speech." )〕 The ''Topeka'' and form a unique sub-class among ''Los Angeles'' class submarines. The pressure hulls of both ships were partially manufactured using stronger HY-100, instead of the HY-80 steel used in the manufacturing of all other ''Los Angeles'' class submarines. This was done to test construction methods using this steel, which would later be employed in the assembly of the new s. In theory, this permits the ''Albany'' and ''Topeka'' to dive to a slightly greater depth than any other member of the ''Los Angeles'' class, though it remains unclear if this ability has ever been tested by either vessel.〔"The Illustrated Directory of Submarines of the World" 2002, p. 377.〕 == History == In 1993 the mini series ''Submarines: Sharks of Steel'' used the ''Topeka'' to produce segments of their program. During New Year's Eve 2000 the USS ''Topeka'' straddled the international dateline, thus was famously "in two millenniums at once".〔("U.S. NAVY SUBMARINE STRADDLES HISTORY" )〕 In October 2002, after completing a Modernization Period in Pearl Harbor Naval Shipyard, ''Topeka'' shifted homeport to San Diego, California, from Pearl Harbor. In December 2012, the submarine began an overhaul at Portsmouth Naval Shipyard. Earlier that same year the submarine completed a six-month-long deployment in the Western Pacific, covering around 35,000 nautical miles.〔http://www.seacoastonline.com/articles/20121110-NEWS-211100318〕 In May 2015, after miscellaneous repairs at Pearl Harbor Naval Shipyard, the ''Topeka'' shifted homeport to Naval Base Guam as part of the U.S. Navy's rebalance of force into the Pacific. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「USS Topeka (SSN-754)」の詳細全文を読む スポンサード リンク
