Khabarovsk-class Submarine
The ''Khabarovsk'' class, or Project 09851 is a class of nuclear submarines under construction for the Russian Navy. Development The lead submarine ''Khabarovsk'', was slated to be floated in June 2020. However, the launch was delayed. This class of submarines is based on the Borei-class submarine's hull (other sources refers to the Project 949A class - to be verified), but is significantly smaller as it does not have the ballistic missile section. Surface displacement is reported to be about 10,000 tons. The class is intended to carry six Status-6 Oceanic Multipurpose System The Poseidon (russian: Посейдон, "Poseidon", NATO reporting name Kanyon), previously known by Russian codename Status-6 (russian: Статус-6), is an autonomous, nuclear-powered unmanned underwater vehicle under development by Rubin ... long-range nuclear torpedoes, and will be the second submarine to carry this weapon after .

Attack Submarine
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet and Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and missile submarines. Some attack subs are also armed with cruise missiles, increasing the scope of their potential missions to include land targets. Attack submarines may be either nuclear-powered or diesel-electric ("conventionally") powered. In the United States Navy naming system, and in the equivalent NATO system (STANAG 1166), nuclear-powered attack submarines are known as SSNs and their anti-submarine (ASW) diesel-electric predecessors are SSKs. In the US Navy, SSNs are unofficially called "fast attacks". History Origins During World War II, submarines that fulfilled the offensive surface attack role were termed fleet submarines in the U.S. Nav ...

Cruise Missile Submarine
A cruise missile submarine is a submarine that carries and launches cruise missiles (SLCMs and anti-ship missiles) as its primary armament. Missiles greatly enhance a vessel's ability to attack surface combatants and strike land targets, and although torpedoes are a more stealthy option, missiles give a much longer stand-off range, 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' characteristics. Originally early designs of cruise missile submarines had to surface to launch their missiles, while later designs could do so underwater via dedicated vertical launching system (VLS) tubes. Many modern attack submarines can launch cruise missiles (and dedicated anti-ship missiles) from their torpedo tubes while some ...

Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...

Status-6 Oceanic Multipurpose System
The Poseidon (russian: Посейдон, "Poseidon", NATO reporting name Kanyon), previously known by Russian codename Status-6 (russian: Статус-6), is an autonomous, nuclear-powered unmanned underwater vehicle under development by Rubin Design Bureau, capable of delivering both conventional and nuclear warheads. The Poseidon is one of the six new Russian strategic weapons announced by Russian President Vladimir Putin on 1 March 2018. History The first public appearance of Poseidon dates back to September 2015 and cites United States Department of Defense, Pentagon sources. On 10 November 2015, a page of a document that contained information about a secret "oceanic multi-purpose system" called "Status-6" was "accidentally" revealed by Russian NTV (Russia), NTV television channel. The leak happened during Russian President Vladimir Putin's speech denouncing American plans concerning defensive missile technology. Speculation arose as to whether this was a warnin ...

Nuclear Submarine
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a range virtually unlimited, making the only limits on voyage times being imposed by such factors as the need to restock food or other consumables. The limited energy stored in electric batteries means that even the most advanced conventional submarine can only remain submerged for a few days at slow speed, and only a few hours at top speed, though recent advances in air-independent propulsion have somewhat ameliorated this disadv ...

Borei-class Submarine
The Borei class, alternate transliteration Borey, Russian designation Project 955 ''Borei'' and Project 955A ''Borei-A'' (russian: Борей, , Boreas, NATO reporting name Dolgorukiy), are a series of nuclear-powered ballistic missile submarines being constructed by Sevmash for the Russian Navy. The class is projected to replace the Soviet-era Delta III, Delta IV and classes in Russian Navy service. Despite being a replacement for many types of SSBNs, Borei-class submarines are much smaller than those of the Typhoon class in both volume and crew (24,000 tons opposed to 48,000 tons and 107 personnel as opposed to 160 for the Typhoons). In terms of ''class'', they are more accurately a follow-on for the Delta IV-class SSBNs. History The first design work on the project started in the mid-1980s and the construction of the first vessel started in 1996. Previously, a short-lived, smaller parallel design appeared in 1980s with designation Project 935 Borei II. A new submarine ...

Submarine Classes
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of ...
