Submarines Of The People's Liberation Army Navy
The People's Liberation Army Navy Submarine Force (PLANSF) is the submarine service of the People's Liberation Army Navy. It consists of all types of submarines in operational service organized into three Naval fleet, fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet. Submarines have long been one of the three focuses of the People's Liberation Army Navy (the other two are aircraft and major surface combatants), and when the decision was made in late 2006 to concentrate on building other principal surface combatants to strengthen the air defense and to further delay the construction of aircraft carriers due to insufficient air cover, submarines will continue to play the lead dominant role in the assault force for the PLAN. Currently, PLANSF operates a fleet of 66 submarines which include nuclear as well as conventional submarines. Its surface branch counterpart is the People's Liberation Army Navy Surface Force.

Naval Ensign Of The People's Republic Of China
A navy, naval force, military maritime fleet, war navy, or maritime force is the military branch, branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of a navy also may incorporate nuclear deterrence by use of submarine-launche ...

Type 093 Submarine
The Type 093 submarine (NATO reporting name: Shang class) is a class of nuclear-powered attack submarines constructed by the People's Republic of China for the People's Liberation Army Navy (PLAN). Development The first-generation of Chinese nuclear submarines, the Type 091 attack and the Type 092 ballistic missile submarines (SSBN), were costly for their limited capability. There was little political support for further development after the Cultural Revolution; they were not a priority in Deng Xiaoping's Four Modernizations. Research on design and foreign developments continued throughout the 1980s, with a new reactor design in development by 1987. Support for new nuclear submarines emerged in 1994 under Jiang Zemin after the 1993 Yinhe incident and continued tensions with Taiwan. Reportedly, Russian experts contributed to the Type 093's design. The first boat was laid down in 1994 and commissioned in 2006. The first two boats had unsatisfactory speed and noise. Further boats ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 virtually unlimited range, making the only limits on voyage times factors such as the need to restock food or other consumables. Thus nuclear propulsion solves the problem of limited mission duration that all electric ( battery or fuel cell powered) submarines face. The high cost of nuclear technology means that relatively few of the world's military powers have fielded nuclear submarines. Radiation incidents have occurred wit ...

Ballistic Missile Submarine
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect (see acoustic signature), thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence. The deployment of ballistic missile submarines is dominated by the United States, Russia (following the collapse of the Soviet Union) and China. In fact, 70% of nuclear warheads in the USA are carried by ballistic missile submarines.Rafal, A. S. (2021).

Victor-class Submarine
The Victor class, Soviet designations Project 671 ''Yorsh'', Project 671RT ''Syomga'' and Project 671RTM/RTMK ''Shchuka'', (List of NATO reporting names for submarines, NATO reporting names Victor I, Victor II and Victor III, respectively), are series of Nuclear submarine, 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 hull, teardrop shape, allowing them to travel at high speed. These vessels were primarily designed to protect Soviet surface fleets and to attack United States Navy, 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).

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in the older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involve a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Los Angeles-class Submarine
The ''Los Angeles'' class of submarines are nuclear-powered fast attack submarines ( 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 2024, 24 of the ''Los Angeles'' class remain in commission—more than any other class in the world—and they account for almost half of the U.S. Navy's 50 fast attack submarines. Submarines of this class are named after American towns and cities, such as Albany, New York; Los Angeles, California; and Tucson, Arizona, with the exception of , named for the " father of the nuclear Navy." This was a change from traditionally naming attack submarines after marine animals, such as or . Rickover explained the decision to name the submarines after cities (and occasionally politicians influential in defense issues) by observing that "fish don't vote." Development In the lat ...

Task Force
A task force (TF) is a unit or formation established to work on a single defined task or activity. Originally introduced by the United States Navy, the term has now caught on for general usage and is a standard part of NATO terminology. Many non-military organizations now create "task forces" or task groups for temporary activities that might have once been performed by '' ad hoc (designated purpose)'' committees. In non-military contexts, working groups are sometimes called task forces. Military Naval Army In the U.S. Army, a task force is a battalion-sized (usually, although there are variations in size) ''ad hoc'' unit formed by attaching smaller elements of other units. A company-sized unit with an armored or mechanized infantry unit attached is called a ''company team''. A similar unit at the brigade level is called a '' brigade combat team'' (BCT), and there is also a similar '' Regimental combat team'' (RCT). In the British Army and the armies of other Common ...

Anechoic Tile
__NOTOC__ Anechoic tiles are rubber or synthetic polymer tiles containing thousands of tiny voids, applied to the outer hulls of military ships and submarines, as well as anechoic chambers. Their function is twofold: *To absorb the sound waves of active sonar, reducing and distorting the return signal, thereby reducing its effective range. *To attenuate the sounds emitted from the vessel, typically its engines, to reduce the range at which it can be detected by passive sonar. Development in the Third Reich The technology of anechoic tiles was developed by the ''Kriegsmarine'' during the Second World War, codenamed ''Alberich'' after the invisible guardian dwarf of the Rhinegold treasure from Richard Wagner's Der Ring des Nibelungen music dramas. The coating consisted of sheets approximately square and thick, with rows of holes in two sizes, and in diameter. Manufactured by IG Farben as a specially formed synthetic rubber tile and made using a stabilized, non-polar, hig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...
