The eleventh HMS ''Vanguard'' of the Royal Navy is the lead boat of her class of Trident ballistic missile-armed submarines. The submarine is based at Faslane, HMNB Clyde, Argyll, Scotland. ''Vanguard'' was built at Barrow-in-Furness by Vickers Shipbuilding and Engineering Ltd (now BAE Systems Submarine Solutions), was launched on 4 March 1992, and commissioned on 14 August 1993. She has two crews, "Port" and "Starboard".〔http://www.royal-navy.mod.uk/linkedfiles/referencelibrary/ref_library_docs/20110603bridgecard03jun11.pdf〕 ==Operational history== The submarine's first commanding officer was Captain David Russell. In February 2002, ''Vanguard'' began a two-year refit at HMNB Devonport. The refit was completed in June 2004 and in October 2005, ''Vanguard'' completed her return to service trials (Demonstration and Shakedown Operations) with the firing of an unarmed Trident missile. During this refit, ''Vanguard'' was illegally boarded by a pair of anti-nuclear protestors.〔(BBC News, 13 March 2003 )〕 On 4 February 2009, ''Vanguard'' collided with the French submarine ''Triomphant'' in the Atlantic.〔 〕 She returned to Faslane in Scotland under her own power, arriving on 14 February 2009. In January 2012 radiation was detected in the PWR2 test reactor's coolant water, caused by a microscopic breach in fuel cladding. This discovery led to ''Vanguard'' being scheduled to be refuelled in its next "deep maintenance period", due to last 3.5 years from 2015, and contingency measures being applied to other ''Vanguard'' and ''Astute'' class submarines, at a cost of £270 million. This was not revealed to the public until 2014. 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「HMS Vanguard (S28)」の詳細全文を読む スポンサード リンク
