In 2012, as part of an ambitious rebuilding effort, President Vladimir Putin announced a plan to build 51 modern ships and 24 submarines by 2020. Of the 24 submarines, 16 will be nuclear-powered. On 10 January 2013, the Russian Navy finally accepted its first new "Borei"-class SSBN ("Yury Dolgorukiy") for service. A second "Borei" ("Aleksandr Nevskiy") was undergoing sea trials and entered service on 21 December 2013. A third "Borei-"class boat ("Vladimir Monomakh") was launched and began trials in early 2013, and was commissioned in late 2014.
