Zvezdochka Shipyard has completed the repair of the Project 667BDRM Delfin-class strategic nuclear-powered ballistic missile submarine (SSBN) Tula (K-114).
The repairing of the SSBN was carried out within the Navy Main Command Plan stipulating for maintenance of nuclear-powered submarines of third generation together with construction of the fourth-generation ones.
The Zvezdochka Shipyard started depot repair of the SSBN Tula in 2015. The submarine has undergone all the factory sea trials, and will return to home station in the Northern Fleet in the near future.
Tula (K-114) (К-114 Тула) is a Project 667BDRM Delfin-class (NATO reporting name: Delta-IV) nuclear-powered ballistic missile submarine (SSBN).
As such, she carries a complement of R-29RM Shtil and R-29RMU Sineva nuclear submarine-launched ballistic missiles (SLBM) as her primary deterrent mission, along with anti-ship missiles and torpedoes, the latter for self-defense.
Built in Severodvinsk during the late 1980s, she served with the Soviet Navy before being transferred to the Russian Navy following the dissolution of the Soviet Union.
Tula underwent an extensive overhaul during 2000–2004 and was fitted with upgraded Shtil SLBMs, several of which were launched from her during her later operational life. She was sponsored by the city of Tula, and is homeported in Gadzhiyevo.
