In recent years, Russia has been putting many efforts in building a modern-day nuclear submarine fleet.
The Russian Navy expects to receive the Project 955A nuclear submarine Prince Vladimir and the Project 885M Yasen-M nuclear-powered underwater cruiser Kazan in 2017, said Russian Navy Deputy Commander-in-Chief Vice-Admiral Viktor Bursuk in a statement.
"The first improved Project 955-A submarine and the Yasen-M will be floated out within the time limits stipulated by the contract," the vice-admiral said.
Three submarines of this class have already been delivered to the Navy, according to Sputnik.
Yasen-class project 885 submarines, designed by St. Petersburg's Malachite mechanical engineering bureau, are Russia's newest class of submarines, while the Borei-class nuclear-powered subs are to become the mainstay of the naval component of the country’s strategic nuclear deterrent.
Meanwhile the eighth Borei-class (project 955) submarine was laid down at the Sevmash shipyard.
The new missile-carrying strategic submarine was named the Knyaz Pozharsky. It is expected to be the last in a series of eight Borei-class submarines for the Russian Navy.
