94th Bombardment Wing
The Type 094 (; Chinese designation: 09- IV; NATO reporting name: Jin class) is a class of ballistic missile submarine developed by China for the People's Liberation Army Navy Submarine Force. The Type 094 succeeds the Type 092 submarine and precedes the Type 096 submarine, which is under development. Background The Type 094 was first spotted in 2006 on commercial satellite imagery of the Xiaopingdao Submarine Base. It was noted as being longer than the Type 092. Two Type 094s were spotted at the Bohai Shipyard in May 2007, although it was not clear if these included the one spotted in 2006. One was operational in 2010, three in 2013, four in 2015, and possibly six in 2020. The PRC is interested in augmenting its ICBM forces with SSBNs to enhance its comprehensive nuclear deterrent force. Nuclear deterrent patrols commenced in December 2015. Description The Type 094's design is likely based on the Type 093 nuclear attack submarine. It was initially armed with 12 JL-2 ...

ICBM
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sail (submarine)
In naval parlance, the sail (American usage) or fin (British/Commonwealth usage) (also known as a fairwater) of a submarine is the tower-like structure found on the dorsal (topside) surface of submarines. Submarine sails once housed the conning tower (command and communications data center), the periscope(s), radar and communications masts (antenna), though most of these functions have now been relocated to the hull proper (and so the sail is no longer considered a "conning tower"). When above the water's surface, the sail serves as an observation platform. It also provides an entrance and exit point on the submarine that has enough freeboard to prevent the submarine being swamped. Under water, the sail acts as a vertical stabilizer. In some submarines, the sail also supports diving planes (or fairwater planes), which are control surfaces used for underwater stability and steering.Office of Naval ResearchSubmarines - How They Work.

South China Sea
The South China Sea is a marginal sea of the Western Pacific Ocean. It is bounded in the north by the shores of South China (hence the name), in the west by the Indochinese Peninsula, in the east by the islands of Taiwan and northwestern Philippines (mainly Luzon, Mindoro and Palawan), and in the south by Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around . It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan (e.g. the Mindoro and Balabac Straits), the Strait of Malacca via the Singapore Strait, and the Java Sea via the Karimata and Bangka Straits. The Gulf of Thailand and the Gulf of Tonkin are also part of the South China Sea. The shallow waters south of the Riau Islands are also known as the Natuna Sea. The South China Sea is a region of tremendous economic and geostrategic importance. One-third of the world's maritime shipping passe ...

Continental United States
The contiguous United States (officially the conterminous United States) consists of the 48 adjoining U.S. states and the Federal District of the United States of America. The term excludes the only two non-contiguous states, Alaska and Hawaii (also the last ones admitted to the Union), and all other offshore insular areas, such as American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. The colloquial term "Lower48" is used also, especially in relation to just Alaska (Hawaii is farther south). The related but distinct term continental United States includes Alaska (which is also on the continent of North America but separated from the 48 states by British Columbia and Yukon of Canada), but excludes the Hawaiian Islands and all U.S. territories in the Caribbean and the Pacific. The greatest distance (on a great-circle route) entirely within the contiguous U.S. is 2,802 miles (4,509 km), between Florida and the State of Washington; th ...

Delta III-class Submarine
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 s, the Delta III class is a double hulled design, with a thin low magnetic steel outer hull wrapped around a thicker inner pressure hull. Design The technical description and requirements for a new ballistic missile submarine were published in 1972. Development of Project 667BDR was begun at the Rubin Central Design Bureau for Marine Engineering under the direction of main designer Sergeiy Nikiticz Kovalev (Сергей Никитич Ковалёв). The submarine was to be a successor to the project 667BD. The Delta III-class submarines are significantly quieter and have a higher missile section for newer, longer-ranged missiles. The hull is divided into ten waterproof sections. The first, third, and tenth sections are emergency sections with escape hatches and transverse struts added to increase pressu ...

Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 10 (approximately ). The unit expresses a relative change or an absolute value. In the latter case, the numeric value expresses the ratio of a value to a fixed reference value; when used in this way, the unit symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is " V" (e.g., "20 dBV"). Two principal types of scaling of the decibel are in common use. When expressing a power ratio, it is defined as ten times the logarithm in base 10. That is, a change in ''power'' by a factor of 10 corresponds to a 10 dB change in level. When expressing root-power quantities, a change in ''ampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Submarine-launched Ballistic Missile
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles. Modern submarine-launched ballistic missiles are closely related to intercontinental ballistic missiles (ICBMs), with ranges of over , and in many cases SLBMs and ICBMs may be part of the same family of weapons. History Origins The first practical design of a submarine-based launch platform was developed by the Germans near the end of World War II involving a launch tube which contained a V-2 ballistic missile variant and was towed behind a submarine, known by the code-name ''Prüfstand XII''. The war ended before it could be tested, but the engineers who had worked o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
