SEVERODVINSK /Arkhangelsk Region/, December 26. /TASS/. The sixth Borei-class nuclear-powered ballistic missile submarine was laid down on Friday at a ceremony at the Sevmash shipyard in Severodvinsk, northern Russia.

Russian Deputy Prime Minister Dmitry Rogozin attended the ceremony.

The Generalissimo Suvorov is the third modified Project 955A submarine. The boat is named after legendary Russian commander Alexander Suvorov, one of the few commanders in history who never lost a battle.

The Project 955 Yuri Dolgoruky, Alexander Nevsky and Vladimir Monomakh submarines have already entered service with the Russian Navy.

The Project 955A Knyaz (Prince) Vladimir and Knyaz Oleg submarines, which were laid down in 2012 and 2014, are currently under construction.

The Borei-class ballistic-missile submarines are to become the backbone of the Russian Navy's strategic nuclear deterrent.

The submarines displace 24,000 tons, reach speeds of 29 knots (some 54 km per hour), can dive to 450 meters and carry crews of 107 people. The vessels will be armed with up to 16 Bulava submarine-launched ballistic missiles, which have range of over 8,000 kilometers.
