K-329 Severodvinsk is a Yasen-class nuclear attack submarine of the Russian Navy. The construction of the submarine started in 1993 and was first planned to be launched in 1998. However budgetary problems delayed the construction for years, and she was only launched on 15 June 2010. She underwent mooring trials and was prepared for the shipyard's sea trials to be started in May 2011. The submarine is expected to begin operational service with the Russian Navy by the end of 2011.
The Russian Navy plans to have two Yasen-class submarines in service by 2015.

Severodvinsks torpedo-launching systems have been fitted behind the compartment of the central station. Severodvinsk began sea trials on 12 September 2011. The submarine returned from her first voyage by 6 October 2011.
