K-535 Yuriy Dolgorukiy is the first Borei-class ballistic missile submarine of the Project 955 in service with the Russian Navy. Named after the founder of Moscow, Yuri Dolgoruki, the vessel was laid down on 2 November 1996 and was first planned to enter service in 2001. However, the R-39M missile that the Borei class was supposed to carry was abandoned after several failed tests, and the submarine was redesigned for the Bulava missile. The Bulava missile is smaller than the original R-39M, and in the 2007 START treaty data exchange it was reported that all Borei-class submarines would carry 16 missiles instead of 12, as originally intended. As of January 2013 the submarine is active with the Russian Navy. Borei II would carry 20 Bulava Missiles, first submarine would be active early 2018.
On 15 April 2007 the submarine was rolled out of the construction hall into a launch dock in Severodvinsk, when the vessel was about 82% complete. The Russian government allocated nearly 5 billion rubles, or 40% of the Navy's 2007 weapons budget, for the completion of the submarine.
There was some speculation that Yuriy Dolgorukiy would be rushed through the rest of the production and testing phases in order to be ready for the 2008 Russian presidential elections. Much of the vessel's equipment remained uninstalled and untested, a process that would normally take over a year to complete.
On 13 February 2008 Yuriy Dolgorukiy was finally launched from the floating dock in Severodvinsk where the final outfitting took place. The submarine's reactor was first activated on 21 November 2008, and the submarine began its sea trials on 19 June 2009.
In July 2010 Yuriy Dolgorukiy passed the first of several company sea trials, in which navigation systems, buoyancy control system, and some other characteristics were tested at sea. All company tests were completed by the end of September 2010 and she was then preparing for state trials.
It was initially planned to conduct the first torpedo launches during the ongoing state trials in December 2010 and then in same month conduct the first launch of the main weapon system, the R-30 (RSM-56) Bulava missile. The plan was then postponed to mid-summer 2011 due to ice conditions in White Sea.
