The first Borei-A-class ballistic missile submarine (SSBN) officially joined the Russian Navy today (June 12). JSC Sevmash Shipyard held a ceremony led by the Commander-in-Chief of the Russian Navy - Admiral Nikolai Yevmenov.

Russia's Sevmash Shipyard has officially handed over the first Borei-A-class submarine to the Russian Navy. The acceptance act for the 'Knyaz Vladimir', the first Project 955A SSBN was signed in Severodvinsk, the Defense Ministry said.

The Project 955A Borei-A class nuclear-powered ballistic missile submarine Knyaz Vladimir (NATO reporting name: Dolgorukiy-class) has completed its sea trials and arrived in Severodvinsk in north Russia, the Defense Ministry’s press office said.

The Knyaz Vladimir Borei A-class nuclear submarine of project 955A began underwater trials in the White Sea before the handover to the Northern fleet, the Defense Ministry said.

The project to build a series of eight SSBN was reported in May 2018 when a defense industry source disclosed a decision to build another six submarines of project 955A at Sevmash Shipyard.

Borei-A-class SSBN of project 955A will operate in the Far East. Five out of eight submarines will serve in the Pacific fleet. The Russian Navy is restoring the Far Eastern nuclear arsenal which was nearly lost thirty years ago.

The Russian Navy will be protected against adversary antisubmarine aircraft and drones. Burak-M buoys will make a sea area impenetrable. Communications by all channels will be jammed or complicated to the maximum by the new system. It is intended for Borey-class SSBN of project 955 and Dolphin-class of project 667BDRM, as well as diesel-electric submarines, the Izvestia writes.
