The Yasen class submarine (Russian: Проект 885 “Ясень”, “ash”), also known as the Graney class (wrong) and Severodvinsk, is a new Russian nuclear multipurpose attack. The class is based on the Akula-class Alpha and is expected to go to replace the Akula class and Oscar class.
The Yasen Class will be the direct antagonists of American Seawolf, since they will be the newest nuclear attack submarines of the Russian Navy beginning of the millennium. The Russians provide, at best, to produce seven boats in the class, bet but it seems a bit ‘risky, given the current state of the Russian military.
Yasen class submarines were designed by SKB-18 design office. Work on the (initial) design began in 1977 and was completed in 1985.
The construction of the first submarine began Dec. 21, 1993. The submarine was scheduled for launch in 1998, but was delayed due to problems of financing the project. In 1996, work on the submarine appeared to have stopped completely. Some sources indicated its completion from 1999 to less than 10 percent. In 2003 the project received additional funding and the finishing work of the submarine continued.
In 2004 it was reported that the work was moving forward, but because of the priority given to the new Borei class SSBN, Severodvinsk, the main unit of the Yasen class I would not be ready before 2010. In July 2006, the vice chairman of the military-industrial complex, Vladislav Putilin said that two Yasen Classes would reach the Russian Navy by 2015.
On 24 July 2009 the work on a submarine Yasen Class, called Kazan, was started. On July 26, the command of the Russian Navy announced that a multi-purpose submarine would be built each year, not necessarily in this class, starting in 2011.
An August 2009 report by the U.S. Office of Naval Intelligence estimated the Yasen, such as less noisy compared to modern nuclear submarines from Russia and China.
In April 2010 it was reported that on May 7 the launch of the first boat had been delayed due to ‘technical reasons’. The beginning of sea trials was reported in September 2011. On 9 November 2011, Russia has signed a contract for 4 Yasen class submarines to be delivered by 2016.
