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 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, or maritime force is the 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 the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...

Type 091 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. The Type 091 has operated mainly in local wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Base
A submarine base is a military base that shelters submarines and their personnel. Examples of present-day submarine bases include HMNB Clyde, Île Longue (the base for France's Force océanique stratégique), Naval Submarine Base Kings Bay, Naval Submarine Base New London, and Rybachiy Nuclear Submarine Base (near Petropavlovsk-Kamchatsky). INS Vajrabahu and INS Satavahana are the submarine bases of the Indian Navy. A new underground submarine base, INS Varsha is under construction near Vishakhapatnam for the new expanding fleet of Indian nuclear submarines. The Israeli navy bases its growing submarine force in Haifa. Former submarine bases include DORA 1, , Naval Submarine Base Bangor (now part of Naval Base Kitsap), Mare Island Naval Shipyard (a nuclear-capable base), Ordnance Island in Bermuda during World War II, and the formerly-classified Soviet base at Balaklava in the now Autonomous Republic of Crimea.

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 ...

Ballistic Missile Submarine
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. The United States Navy's hull classification symbols for ballistic missile submarines are SSB and SSBN – the ''SS'' denotes submarine, the ''B'' denotes ballistic missile, and the ''N'' denotes that the submarine is nuclear powered. 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 SSBNs is dominated by the United States and Russia (following the collapse of the Soviet Union). Smaller numbers are in service with France, the United Kingdom, China and India; North Korea is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Anti-submarine Warfare
Anti-submarine warfare (ASW, or in 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 involved 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 instan ... [...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 definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

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 ...

Carrier Battle Group
A carrier battle group (CVBG) is a naval fleet consisting of an aircraft carrier capital ship and its large number of escorts, together defining the group. The ''CV'' in ''CVBG'' is the United States Navy hull classification code for an aircraft carrier. The first naval task forces built around carriers appeared just prior to and during World War II. The Imperial Japanese Navy (IJN) was the first to assemble many carriers into a single task force, known as ''Kido Butai''. This task force was used with devastating effect in the Japanese attack on Pearl Harbor. Kido Butai operated as the IJN's main carrier battle group until four of its carriers were sunk at the Battle of Midway. In contrast, the United States Navy deployed its large carriers in separate formations, with each carrier assigned its own cruiser and destroyer escorts. These single-carrier formations would often be paired or grouped together for certain assignments, most notably the Battle of the Coral Sea and ...

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, high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
