Russian submarine K-550 ''Alexander Nevsky'' is a Russian nuclear ballistic missile submarine of the fourth generation (Project 955A). Named after the Russian saint Alexander Nevsky, the submarine was laid down in March 2004 and was first planned to be launched in 2009. However budgetary problems and repeated failures of the submarines main weapon, the Bulava SLBM missile, pushed the launch date forward. Russian officials have however claimed that the submarine has been completed on time and even ahead of schedule.〔 ==Design and description== The submarine was to have been rolled out from its construction hall on 30 November 2010. This was postponed to December due to bad weather, according to the shipyard's press service. On 2 December 2010 the submarine was rolled out from its construction hall to floating dock and would be launched at an unknown future date. The submarine was inspected by the Russian Prime Minister, Vladimir Putin on 13 December 2010. With an estimated cost of 23 billion RUR (~$900 million USD), the new submarine has no significant differences from the lead ship, SSBN .〔 On 24 October 2011 the submarine started its sea trials. It was planned to launch the first SLBM from ''Alexander Nevsky'' in 2012. The submarine entered service on 23 December 2013. 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「Russian submarine Alexander Nevsky (K-550)」の詳細全文を読む スポンサード リンク
