K-549 Knyaz Vladimir (Russian: АПЛ Князь Владимир) is a Borei-class nuclear-powered ballistic missile submarine, and the first upgraded Borei-A (Project 955A) unit to enter service with the Russian Navy. The submarine is named after Prince Vladimir the Great.


Project 955A was developed by the Rubin Design Bureau, and the chief designer was Sergey Kovalev. The keel was expected to have been laid down in 2010 but this was delayed until July 2012 because of a price dispute between the Russian MOD and the United Shipbuilding Corporation.[1]

Knyaz Vladimir is the first unit of the Project 955A sub-class and will differ by several modifications from the previous units of the project 955. These modifications will include major structural changes, reduced acoustic signature, and more modern communication equipment. While initially reported to have four more (20 in total) launch tubes, the 955A includes 16 missile tubes same as the project 955.[2] [3]The submarine will be armed with the newest Russian submarine launched ballistic missile (SLBM), the RSM-56 Bulava. Knyaz Vladimir and its sister ships will eventually replace the Soviet-era Delta and Typhoon-class submarines in the Russian Navy.

Knyaz Vladimir was floated out on 17 November 2017,[4] and began the first stage of factory trials by late November 2018.[5] The submarine returned back to Sevmash in early 2019 and was to begin a second stage of factory trials by late June 2019.[6]
