Submarine
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 Autonomous underwater vehicle, 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 navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

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 ...

Qing-class Submarine
The Type 032 submarine ( NATO reporting name: Qing-class) is a class of diesel-electric submarine currently undergoing testing in China's People's Liberation Army Navy. It is said to be the world's largest conventional submarine, at a submerged displacement of 6,628 tonnes and is able to submerge for a maximum of 30 days. Design The Type 032 has a similar ventral "bay" to the Golf-class submarine that protrudes downward. The project for this double hulled submarine begun in January 2005, and construction begun at Wuhan Shipyard in 2008. The submarine was launched on September 10, 2010, and sea trials were completed in September 2012. The submarine entered service on October 12, 2012 with pennant number 201. The submarine is a testbed for new technologies such as combustion powered torpedoes, compartments for special forces, underwater unmanned vehicles, new SLBMs, new cruise missiles, new anti ship missiles, new SAMs, and a new escape pod which are applied to the Type 095 an ...

Air-independent Propulsion
Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels. Modern non-nuclear submarines are potentially stealthier than nuclear submarines; although some modern submarine reactors are designed to rely on natural circulation, most naval nuclear reactors use pumps to constantly circulate the reactor coolant, generating some amount of detectable noise. Non-nuclear submarines running on battery power or AIP, on the other hand, can be virtually silent. While nuclear-powered designs still dominate in submergence times, speed, range and deep-ocean performance; small, high-tech non-nuclear attack submarines can be highly effective in coastal operations and pose a significant threat to less-stealthy and less-maneuverable nuclear submarines. AIP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virginia-class Submarine
The ''Virginia'' class, also known as the SSN-774 class, is a class of nuclear-powered cruise missile fast-attack submarines, in service in the United States Navy. Designed by General Dynamics Electric Boat (EB) and Huntington Ingalls Industries, the ''Virginia'' class is the United States Navy's latest submarine model, which incorporates the latest in stealth, intelligence gathering, and weapons systems technology. ''Virginia''-class submarines are designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. They are scheduled to replace older s, many of which have already been decommissioned. ''Virginia''-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to remain into the 2070s. History The class was developed under the codename Centurion, later renamed New SSN (NSSN). The "Centurion Study" was initiated in ...

Victor-class Submarine
The Victor class, Soviet designations Project 671 ''Yorsh'', Project 671RT ''Syomga'' and Project 671RTM/RTMK ''Shchuka'', (NATO reporting names Victor I, Victor II and Victor III, respectively), are series of nuclear-powered attack submarines built in the Soviet Union and operated by the Soviet Navy. Since the 1960s, 48 units were built in total, of which the last remaining are currently in service with the Russian Navy. The Victor-class submarines featured a teardrop shape, allowing them to travel at high speed. These vessels were primarily designed to protect Soviet surface fleets and to attack American ballistic missile submarines. Project 671 began in 1959 with the design task assigned to SKB-143 (one of the predecessors of the Malakhit Marine Engineering Bureau). Versions Project 671 ''Yorsh'' (Victor I) Soviet designation Project 671 ''Yorsh'' (ruffe)—was the initial type that entered service in 1967; 16 were produced. Each had six torpedo tubes for launching Type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trafalgar-class Submarine
The ''Trafalgar'' class is a class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy, and the successor to the . Like the majority of Royal Navy nuclear submarines, all seven boats were constructed at Barrow-in-Furness shipyard, Cumbria. With only one boat remaining active and in commission (as of 2022) and six retired from the seven originally in service, the class makes up part of the Royal Navy's nuclear-powered ‘hunter-killer’ submarine force. The ''Trafalgar'' class is being gradually replaced by the larger and more capable , of which five are currently commissioned. The name ''Trafalgar'' refers to the Battle of Trafalgar fought between the Royal Navy and the combined fleets of France and Spain in 1805. Development The ''Trafalgar'' class were designed in the early 1970s during the Cold War as a refinement of the preceding ''Swiftsure'' class. Including , the ''Trafalgar'' class are the fifth class of nuclear-powered fleet submarines to enter ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra-class Submarine
The Sierra class, Soviet designations Project 945 ''Barrakuda'' and Project 945A ''Kondor'', (NATO reporting names Sierra I and Sierra II respectively), are series of nuclear-powered attack submarines intended for the Soviet Navy and currently in service with the Russian Navy. The class is unique due to its light and strong titanium pressure hull which enables the submarines of the class to dive to greater depths, reduce the level of radiated noise and increase resistance to torpedo attacks. It is powered by a single OK-650 pressurized water reactor. The upgraded version, the Sierra II class was specifically developed for search and destroy missions against US nuclear submarines. It has speeds and diving depth greater than its American counterparts at the time it was designed. It has also improved quieting and sonar. Versions Project 945 ''Barrakuda'' (Sierra I) The first submarine of the Project 945, ''Carp'', was laid down in July 1979 at the Gorky shipyard and was launc ...

Seawolf-class Submarine
The ''Seawolf'' class is a class of nuclear-powered, fast attack submarines (SSN) in service with the United States Navy. The class was the intended successor to the , and design work began in 1983. A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines. The end of the Cold War and budget constraints led to the cancellation of any further additions to the fleet in 1995, leaving the ''Seawolf'' class limited to just three boats. This, in turn, led to the design of the smaller . The ''Seawolf'' class cost about $3 billion per unit ($3.5 billion for ), making it the most expensive United States Navy fast attack submarine and second most expensive submarine ever, after the French nuclear-powered ballistic missile submarines. Design The ''Seawolf'' design was intended to combat the threat of advanced Soviet ballistic missile submarines such as the , and attack submarines such as the in a deep-ocean environment. ''Seawolf''-class hull ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubis-class Submarine
The ''Rubis'' class is a series of nuclear-powered attack submarines operated by the French Navy. The class comprises six vessels, the first entering service in 1983 and the last in 1993, with another two being cancelled. All six submarines of the ''Rubis'' class are based at Toulon and are part of the ''Escadrille de sous-marins nucléaires d'attaque''. Smaller than contemporary designs of other major world navies, the ''Rubis'' class shares many of its system designs with the conventionally-powered . In the late 1980s, the ''Rubis'' class was proposed as an export to Canada in their plan to acquire nuclear-powered submarines. The submarines of the class were built in two batches, with the final two built to an improved standard to reduce noise emissions that plagued the original design. Dubbed the AMÉTHYSTE rebuild, the first four hulls were refitted to its standard until they were practically indistinguishable from the final two hulls. Four of the submarines have had signifi ...

Los Angeles-class Submarine
The ''Los Angeles'' class of submarines are Nuclear marine propulsion, nuclear-powered fast attack submarines (hull classification symbol, SSN) in service with the United States Navy. Also known as the 688 class (pronounced "six-eighty-eight") after the hull number of lead vessel , 62 were built from 1972 to 1996, the latter 23 to an improved 688i standard. As of 2022, 26 of the ''Los Angeles'' class remain Ship commissioning, in commission — more than any other class in the world — and they account for more than half of the U.S. Navy's 50 fast attack submarines. Of the 34 retired boats, a few were in commission for nearly 40 years, including , and . With a wide variance in longevity, 12 of the 688s were laid up halfway through their projected lifespans, being the youngest-retired at 15 years, 11 months. Another five also laid up early (20–25 years), due to their Refueling and overhaul, midlife reactor refueling being cancelled, and USS Miami (SSN-755)#2012 fire, one was l ...

Han-class Submarine
The Type 091 (Chinese designation: 09- I; NATO reporting name: Han class) is a first-generation nuclear-powered attack submarine produced by China. It was the first nuclear submarine employed by the People's Liberation Army Navy Submarine Force, and the first indigenously-produced nuclear attack submarine in Asia. Background The Chinese naval nuclear power program started in July 1958 when the Central Military Commission gave approval to start the Type 091 submarine project. Mao Zedong declared that China would build nuclear attack submarines "even if it took ten thousand years." Peng Shilu was the first chief designer of this project. The first submarine in the class, ''Changzheng 1'' ("Long March 1"), was commissioned in 1974; the last was launched in 1990.Erickson and Goldstein (2007: 58) In 1983, Peng moved to the civilian development of nuclear power plants, and he was succeeded at the nuclear submarine project by Huang Xuhua.
