Borei-class Nuclear Ballistic Missile Submarine

The Project 955/A/B Borei-class is the new class of nuclear-powered ballistic missile submarine produced by Russia and operated by the Russian Navy, while the Severodvinsk-class submarine is the new Russian attack submarine. The class is intended to replace the Delta III, Delta IV and Typhoon classes now in Russian Navy service. The class is named after Boreas, the North wind.

Despite being a replacement for many types of the Borei-class submarines are much smaller than those of the Typhoon-class in length, volume, and crew (560 feet (170.69 meters) as opposed to 574 feet (174.96 meters), 24,000 tons opposed to 48,000 tons and 107 people as opposed to 160 for the Typhoons. Borei is more accurately a follow-on to a replacement for the Delta IV-class SSBNs. These changes were in part designed to reduce the cost to build and maintain the submarines.

In November 2017, Russia began development work of Project 955B.
