Russian Navy Submarine Knyaz Vladimir Completes State Trials

The Russian Navy’s new Borei-A-class ballistic missile submarine Knyaz Vladimir has completed the cycle of state trials and arrived at the Northern Fleet’s Belomorsk naval base, TASS reported.

“The latest Project Borei-A strategic underwater cruiser Knyaz Vladimir has completed state trials at the Northern Fleet’s combat training ranges in the White Sea and arrived in Severodvinsk,” the Northern Fleet’s press office said in a statement.

During the trials, the submarine conducted the first test-firing of a Bulava submarine-launched ballistic missile (SLBM). The missile was fired by the submarine while submerged in the White Sea to the Kura Missile Test Range, located on the Kamchatka Peninsula in Russian Far East.

Knyaz Vladimir is the Russian Navy’s fourth Project 955 Borei-class nuclear-powered ballistic missile submarine (SSBN) and the first of the upgraded Project 955A Borey-A class. She is named after Prince Vladimir the Great.

The submarine was laid down on 30 July 2012, floated out on 17 November 2017, and began the first stage of factory trials by late November 2018.

The submarine has a surface displacement of 14,720 tonnes and a submerged displacement of 24,000 tonnes. The Borei has a maximum operating depth of 400 meters and can develop a surface speed of 15 knots and a submerged speed of up to 29 knots. It has a sea endurance of 90 days and a crew of 107.

The submarine will be armed with the newest submarine-launched ballistic missile (SLBM) developed in Russia, the R-30 (RSM-56) Bulava (NATO designation: SS-NX-32). Borey-A class boats have 16 missile tubes each. If armed with Bulava SLBMs with ten warheads atop each, a single Borei-class SSBN could then carry 160 warheads.

The first three Borei-class submarines – the Yury Dolgoruky, the Alexander Nevsky and the Vladimir Monomakh – have been already actively deployed by the Navy and have conducted multiple Bulava launches.

Knyaz Vladimir and its sister ships will eventually replace the Soviet-era Delta and Typhoon-class submarines of the Russian Navy.
