The Russian Ministry of Defence (MoD) is planning to begin construction of a fifth Borey-class nuclear-powered ballistic-missile submarine in late 2014.

RIA Novosti cited Russian Navy commander-in-chief admiral Viktor Chirkov saying construction of another Borey will start within a year during a conference on prospects of military shipbuilding until 2050

The Russian Navy commissioned its first Borey-class submarine, Yury Dolgoruky, in January.

According to Russia’s United Shipbuilding Corporation, the second submarine of the class, Alexander Nevsky, is due to be delivered to the Russian Navy at the end of November or in early December 2013.

"The 170.5m-long Borey-class submarines have a crew capacity of 130 and are powered by an OK-650 nuclear reactor."

Vladimir Monomakh, the third Borey-class boat, is undergoing sea and state trials while the fourth submarine, Knyaz Vladimir has been under construction at the Sevmash shipyard since July 2012.
