Russia's first modern nuclear attack submarine, the Severodvinsk, was delivered to its navy Monday, a defense official confirmed.
The submarine, designated Yasen-class by the Russian military and Graney-class by NATO, had been under construction since 1993 at the Sevmash shipyard in the Arctic Sea city of Severodvinsk, the Russian news agency RIA Novosti reported.
It is the first of eight in a series, ordered by the navy, projected to replace Soviet-era nuclear attack submarines.
The sub, which carries cruise missiles, self-guided torpedoes and mines, has a length of 119 meters (390 feet), can dive to depth of 600 meters (1,968 feet) and carries a crew of 90, RIA Novosti said.
