Russia has about 14 nuclear-powered fast attack submarines and 11 nuclear- powered cruise missile submarines. Additionally, it operates around 12 nuclear-powered, nuclear-armed ballistic missile submarines (SSBNs), consisting of five Delta-class and seven Borei-class vessels. Overall, Russia's nuclear submarine fleet is estimated to be around 37 submarines by combining these figures, but specific counts can vary slightly depending on new commissions and retirements. This includes the strategic ballistic missile submarines central to its nuclear deterrent.
