The Borei class (or Borey; Russian: Борей, named after Boreas) is a type of nuclear-powered ballistic missile submarine (SSBN) produced and operated by Russia. It is intended to replace the Delta III and Typhoon class in the Russian Navy.

Work on the first unit of the Borei class (officially designated Project 935) started in 1996. A new submarine-launched ballistic missile was developed in parallel, called the SS-N-28. However, the work on the SS-N-28 was abandoned, and a new missile called the SS-NX-30 Bulava was designed. The submarine needed to be redesigned to accommodate the new missile, and the project name was changed to Project 955. The vessels are being built in Sevmash by Rubin Design Bureau.

The Borei is claimed to represent the state of the art in submarine design, incorporating characteristics that make it superior to any submarine currently in service, such as the ability to cruise silently and be less detectable to sonar. Advances include a compact and integrated hydrodynamically efficient hull for reduced broad band noise and the first ever use of pump-jet propulsion on a Russian nuclear submarine.Russian Borei Class Submarine Costing some $890 million USD,Би-би-си | Россия | Россия спустила на воду атомную подлодку Borei is approximately 170 metres long, 10 metres in diameter, and has a maximum submerged speed of at least 46 kilometers per hour (25 knots). Smaller than the Typhoon class, the Borei was initially slated to carry the same number of missiles, 20, but has been forced to sacrifice 4 missiles due to the increase in mass of the 45 ton Bulava SLBM (a modified version of the Topol-M ICBM) over the proposed SS-N-28.

The launch of the first submarine of the class, the Yury Dolgoruky, was scheduled for 2002 but was delayed because of budget constraints. The vessel was eventually launched on April 15, 2007 in a ceremony attended by many senior military and industrial personnel.Russia to launch new nuclear submarine First RF submarine hits the water; Missile defense update The Yury Dolgoruky was the first strategic missile submarine to be launched in 17 years since the end of the Soviet era; in fact, it was the first Russian (rather than Soviet) vessel. Currently, there are two more Borei class submarines under construction, named Alexander Nevsky and Vladimir Monomakh. The planned contingent of 12 strategic submarines is expected to be commissioned within the next decade (5 "project 955" are planned for purchase to 2015(Russian) ВЕДОМОСТИ - Оружия не хватит - Для переоснащения армии нет средств).
