Borei-class Nuclear Ballistic Missile Submarine

The 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 submarines, the Borei-class submarines are slightly smaller than the Typhoon-class in length (560 feet (170.69 meters) as opposed to 574 feet (174.96 meters)) and crew (107 people). 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.
