Russia's Twin Underwater Threat: 885 M-Class and Borei-Class Nuclear Submarines (Short Overviews)

Overview of Russia Navy’s Perm Yasen M-Class Nuclear Multi-Purpose Submarine and Prince Pozharsky Borei-Class Nuclear Ballistic Missile Submarine.

The Severodvinsk-class submarine (Russian: Проект 885 "Ясень", "ash tree"; NATO reporting name: "Severodvinsk", also known erroneously as the Graney class) is the newest Russian nuclear-powered multipurpose attack submarine. Based on the Akula-class submarine and the Alfa-class submarine, it is projected to replace Russia's Soviet-era attack submarines, both the Akula and Oscar-class submarines.

According to one of the U.S. Navy’s top submarine officers Rear Adm. Dave Johnson, Naval Sea Systems Command’s (NAVSEA) program executive officer (PEO) submarines, "We’ll be facing tough potential opponents. One only has to look at the Severodvinsk, Russia’s version of a [nuclear guided missile submarine] (SSGN). I am so impressed with this ship that I had Carderock build a model from unclassified data [so that he could look at it every day on his way to his office].”

The Borei class (Russian: Борей; transliterated as Borey, NATO Reporting Name: Dolgorukiy class, after the name of the lead vessel, Yury Dolgorukiy) 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 much smaller than those of the Typhoon class in both volume and crew (107 people as opposed to 160 for the Typhoons). The goal of this downsizing is to reduce the cost to build and maintain the submarines.
