The Russian Navy will receive a second Graney Class nuclear-powered multipurpose attack submarine, the Kazan, in 2015, a Malakhit design bureau spokesman said.

“The hull of the Kazan submarine has been built, but we still have to make many upgrades on the first vessel in the series. We are planning to deliver the submarine to the navy in 2015,” the official added.

Construction began in 2010 at the Sevmash Shipyard in the northern Russian city of Severodvinsk.

The second submarine will feature more advanced equipment and weaponry than the first vessel, the Severodvinsk, according to RIA Novosti.

The Graney Class submarines are designed to launch long-range cruise missiles with conventional or nuclear warheads and are equipped with 24 cruise missiles, eight torpedo launchers, mines and anti-ship missiles.

The first vessel will enter service by the end of 2011.
