The Yasen-class submarine (Russian: Проект 885 "Ясень", "ash tree"; NATO reporting name: "Severodvinsk", also known erroneously as the ''Graney'' class) is the newest Russian nuclear-powered multipurpose attack submarine. Based on the and the s it is projected to replace Russia's Soviet-era attack submarines, both ''Akula'' and s. According to one of the U.S. Navy’s top submarine officers Rear Adm. Dave Johnson, Naval Sea Systems Command’s (NAVSEA) program executive officer (PEO) submarines, "We’ll be facing tough potential opponents. One only has to look at the Severodvinsk, Russia’s version of a (guided missile submarine ) (SSGN). I am so impressed with this ship that I had Carderock build a model from unclassified data (that he could look at it every day on his way to his office ).” ==History== Yasen-class submarines were designed by the Malakhit Central Design Bureau, formed by the combination of SKB-143 and TsKB-16, with work on the initial design scheduled for start in 1977 and completion in 1985. Malakhit is one of the three Soviet/Russian submarine design centers, along with Rubin Design Bureau and Lazurit Central Design Bureau. Construction on the first submarine started on 21 December 1993 with its launch slated for 1995 and commissioning for 1998. However, the project was delayed due to financial problems and it appeared during 1996 that work on the submarine had stopped completely. Some reports suggested that as of 1999 the submarine was less than 10 percent completed. In 2003 the project then received additional funding and the work of finishing the submarine continued. In 2004 it was reported that the work on the submarine was moving forward, but due to the priority given to the new SSBN , ''Severodvinsk'', the lead unit of the Yasen class would not be ready before 2010. In July 2006 the deputy chairman of the Military-Industrial Commission, Vladislav Putilin, stated that two Yasen-class submarines were to join the Russian Navy before 2015. On 24 July 2009, work commenced on a second Yasen submarine, named ''Kazan''. On 26 July, the Russian navy command announced that starting in 2011, one multipurpose submarine would be laid down every year, although not necessarily of this class. An August 2009 report from the U.S. Office of Naval Intelligence estimated the Yasen-class submarines to be the quietest, or least detectable, of contemporaneous Russian and Chinese nuclear submarines but is still not as quiet as contemporary U.S. Navy submarines (i.e. ''Seawolf'' and ''Virginia'' classes). In April 2010 it was reported that the 7 May launch of the first boat had been postponed due to 'Technical Reasons'. The launch of the first ship of this class and the beginning of sea trials was reported in September 2011.〔(【引用サイトリンク】title=Russia's new attack submarine goes for sea trials | Defense | RIA Novosti )〕 K-329 ''Severodvinsk'' went on her first voyage in September 2011 in order to conduct sea trials. On 9 November 2011 Russia signed a contract for 4 Yasen-class submarines to be delivered by 2016. On 26 July 2013 the third submarine, ''Novosibirsk'', was laid down. On 30 December 2013 the first submarine, ''Severodvinsk'', was handed over to the Russian Navy. The flag-raising ceremony was held on 17 June 2014 marking its introduction into the Russian Navy. 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「Yasen-class submarine」の詳細全文を読む スポンサード リンク
