The Oscar class, Soviet designations Project 949 Granit and Project 949A Antey, are a series of nuclear-powered cruise missile submarines designed in the Soviet Union for the Soviet Navy. First built in the 1970s, six remain in service with the Russian Navy. Two other vessels were slated to be modernized since at least 2017 as Project 949AM, to extend their service life and increase combat capabilities but it is unclear whether work continues as of 2023.
The Yankee class, Soviet designations Project 667A Navaga (navaga) and Project 667AU Nalim (burbot) for the basic Yankee-I, were a family of nuclear-powered ballistic missile submarines built in the Soviet Union for the Soviet Navy. In total, 34 units were built: 24 in Severodvinsk for the Northern Fleet and the remaining 10 in Komsomolsk-on-Amur for the Pacific Fleet. Two Northern Fleet units were later transferred to the Pacific.
A cruise missile submarine is a submarine that carries and launches cruise missiles as its primary armament. Missiles greatly enhance a warship's ability to attack surface combatants and strike land targets; although torpedoes are a more discreet option for submerged submarines, missiles give a much longer stand-off range, shorter time to impact the target, as well as the ability to engage multiple targets on different headings at the same time. Many cruise missile submarines retain the capability to deploy nuclear warheads on their missiles, but they are considered distinct from ballistic missile submarines due to the substantial differences between the two weapons systems' flight characteristics; cruise missiles fly aerodynamically using flight surfaces like wings or fins, while a ballistic missile uses its engine power alone as it may exit the atmosphere.
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. In the US classification, nuclear-powered submarines are designated as SSxN, where the SS denotes submarine, x=G means that the submarine is equipped with guided missiles, x=B means that the submarine is equipped with ballistic missiles and the N means that the submarine is nuclear-powered. SSN refers to nuclear-powered attack submarines, which do not carry missiles.
The Akula class, Soviet designation Project 971 Shchuka-B is a series of fourth generation nuclear-powered attack submarines (SSNs) first deployed by the Soviet Navy in 1986. There are four sub-classes or flights of Shchuka-B, consisting of the original seven Project 971 boats, commissioned between 1984 and 1990; six Project 971Is, commissioned between 1991 and 2009; one Project 971U, commissioned in 1995; and one Project 971M, commissioned in 2001. The Russians call all of the submarines Shchuka-B, regardless of modifications.
The Echo class were nuclear cruise missile submarines of the Soviet Navy built during the 1960s. Their Soviet designation was Project 659 for the first five vessels, and Project 675 for the following twenty-nine. Their NATO reporting names were Echo I and Echo II. All were decommissioned by 1994.
The Project 940 Lenok class was a military submarine design of the Soviet Union. Two vessels of this class were built for the Soviet Navy; both were scrapped in the 2000s.
The Delta class, Soviet designations Project 667B Murena, Project 667BD Murena-M, Project 667BDR Kalmar, Project 667BDRM Delfin, are a family of nuclear-powered ballistic missile submarines, designed and built in the Soviet Union, which formed the backbone of the Soviet and Russian strategic submarine fleet since their introduction in 1973. They carry nuclear ballistic missiles of the R-29 Vysota family, with the Delta I, Delta II, Delta III and Delta IV classes carrying the R-29/SS-N-8 'Sawfly', R-29D/SS-N-8 'Sawfly', R-29R/SS-N-18 'Stingray' and R-29RM/SS-N-23 'Skiff' respectively.
The Delta III-class submarine, Soviet designation Project 667BDR Kaľmar (Squid), is a large ballistic missile submarine operated by the Russian Navy. Like other previous Delta-class submarines, the Delta III class is a double hulled design, with a thin low magnetic steel outer hull wrapped around a thicker inner pressure hull.
The Sierra class, Soviet designations Project 945 Barrakuda and Project 945A Kondor,, are a series of nuclear-powered attack submarines intended for the Soviet Navy and currently in service with the Russian Navy.
The Project 670 Skat submarine was a nuclear-powered cruise missile submarine built for the Soviet Navy and later operated by the Russian Navy. All Charlie I/II-class submarines are decommissioned. One Charlie-class submarine was used for testing an Oniks missile. Charlie I and its successor Charlie II-class submarines are designed by the Lazurit Central Design Bureau of Gorky.
B-414 Daniil Moskovsky was a Project 671RTM Schuka attack submarine of the Russian Northern Fleet. The submarine was laid down in 1989, launched and commissioned in 1990. It was known as K-414 before renaming in 1992. In 1994 B-414 took part in joint combat service with SSBN Karelia (K-18) of the Delta IV class. In 1996 the submarine was named after Prince Daniil Moskovsky, the youngest son of Alexander Nevsky.
K-64 was the lead ship of the Project 705 nuclear-powered attack submarines of the Soviet Navy.
B-276 Kostroma is a Russian Sierra-class submarine. She was launched in 1986, commissioned in 1987, and named K-276 Crab until 1992. Kostroma was built at Gorky and later towed to Severodvinsk for completion. She is part of the Russian Northern Fleet.
K-114 Tula is a Russian Project 667BDRM Delfin-class nuclear-powered ballistic missile submarine (SSBN). As such, she carries a complement of R-29RM Shtil and R-29RMU Sineva nuclear submarine-launched ballistic missiles (SLBM) as her primary deterrent mission, along with anti-ship missiles and torpedoes, the latter for self-defense. Built in Severodvinsk during the late 1980s, she served with the Soviet Navy before being transferred to the Russian Navy following the dissolution of the Soviet Union. Tula underwent an extensive overhaul during 2000–2004 and was fitted with upgraded Shtil SLBMs, several of which were launched from her during her later operational life. She was sponsored by the city of Tula, and is homeported in Gadzhiyevo.
Razumnyy was a 1135 Burevestnik-class Large Anti-Submarine Ship or 'Krivak' class frigate that served with the Soviet and Russian Navies. Launched on 20 July 1973, the vessel operated as part of the Pacific Fleet, as a dedicated anti-submarine vessel, with an armament built around the Metel Anti-Ship Complex. The vessel undertook a number of tours, visiting the People's Democratic Republic of Yemen and India. The ship was decommissioned on 16 March 1998 and subsequently disarmed ready to be broken up before the end of the year.
Zadornyy was a Project 1135 Burevestnik-class guard ship or Krivak-class frigate that served with the Soviet and Russian Navies. Displacing 3,200 tonnes full load, the vessel was built around the Metel anti-submarine missile system. Zadornyy was launched on 25 March 1979 in Leningrad, the last of the class to be built by the A.A. Zhdanov shipyard, and served with the Northern Fleet. After taking part in exercises Avangard-81, Sever-81 and Okean-83, and cruising as far as Havana, Cuba, the vessel was upgraded between 11 June 1990 and 23 May 1995 with missiles that added anti-ship capability. While serving with the Russian Navy, the ship took part in joint exercises with frigates of the Royal Navy, including a commemoration of the first Arctic convoy of the Second World War with HMS Campbeltown. After more than twenty-five years service, the ship was decommissioned on 3 December 2005.
Razyashchiy was a Project 1135 Burevestnik-class Large Anti-Submarine Ship or Krivak-class frigate of the Soviet Navy. Displacing 3,200 tonnes full load, the vessel was built around the Metel anti-submarine missile system. Launched on 22 July 1974, Razyashchiy joined the Pacific Fleet of the Soviet Navy. While serving in the Arabian Sea, in 1983, Razyashchiy suffered minor hull damage from colliding with the destroyer USS Fife while approaching a US fleet. The ship also undertook visits to Port Louis, Mauritius, and Danang, Vietnam, to, among other objectives, enhance the relationships between these countries and the Soviet Union. In 1991, the vessel was transferred to the newly-formed Russian Navy. After nearly twenty years of service, however, Razyashchiy was in a poor state and so was decommissioned on 29 October 1992 and sold to be broken up on 6 October 1994.
