Russia's Advanced Borei-class SSBN to Serve Until 2050

The new Borei-class nuclear-powered ballistic missile submarines will serve for more than 30 years due to planned maintenance and modernization. Each commissioned Borei-class SSBN costs more than 23 billion Russian Rubles.

Eight submarines will join—and become the backbone of—the Russian Strategic Naval Forces. They are slowly replacing the ageing Delta III-class and the Typhoon-class SSBN.

Powered by a nuclear reactor, the Borei-class SSBN can reach 30 knots submerged and can dive to 1,400+ feet. With a crew of 107, its range is unlimited but restricted by food supply.

Presently, three Borei-class submarines are already operational:

K-535 Yury Dolgorukiy – commissioned on 10 January 2013, Northern Fleet.
K-550 Aleksandr Nevskiy – commissioned on 21 December 2013, Pacific Fleet.
K-551 Vladimir Monomakh – commissioned on 19 December 2014, Pacific Fleet.

Armed with 16 Bulava missiles, the Borei-class SSBN will be able to launch them to a range up to 10,000 kilometers. The Bulava missile is based on the Topol-M missile and can carry six to ten re-entry vehicles with a yield of 100kt-150kt each.
