Dolphin-class Submarine
The ''Dolphin'' class (Hebrew: הצוללות מסדרת דולפין) is a diesel-electric submarine developed in Israel and constructed by Howaldtswerke-Deutsche Werft AG (HDW) in Kiel, Germany, for the Israeli Navy. The first boats of the class were based on the export-only German 209-class submarines, but modified and enlarged. The ''Dolphin'' 1 sub-class is slightly larger than the German Navy Type 212 in length and displacement. The three newer air-independent propulsion (AIP) equipped boats are similar to the Type 212 vessels in underwater endurance, but are longer, nearly 500 tonnes heavier in submerged displacement and have a larger crew than either the Type 212 or the Type 214. The ''Dolphin 2'' class are the largest submarines to have been built in Germany since World War II. The ''Dolphin''-class boats are the most expensive single vehicles in the Israel Defense Forces. The ''Dolphin'' class replaced the aging , which had served in the Israeli navy since the lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dakar-class Submarine
The ''Dakar''-class submarines (Hebrew : הצוללות מסדרת דקר) is a class of AIP-capable, diesel-electric attack submarines ordered by the Israeli Navy from German-based naval conglomerate ThyssenKrupp Marine Systems (TKMS). Compared to the Israeli Navy's currently-serving s, the ''Dakar'' class features a starkly-new design and has been specifically customised to fulfill the operational requirements specified by the Israeli Navy. The class has been named in honor of , an Israeli-submarine which mysteriously sank in 1968. In January 2022, Israel's Ministry of Defense (מִשְׂרַד הַבִּטָּחוֹן) ordered three submarines - as a replacement to the first batch of the Israeli Navy's ''Dolphin''-class submarines; the first of the new submarines are slated to enter service within nine years. Overview Design Current details about the class' design are scant; however, it is understood that the submarines have been specifically engineered to fulfill th ...

Type 209 Submarine
The Type 209 is a class of diesel-electric attack submarine developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. The original variant (Type 209/1100) was designed in the late 1960s. The class is exclusively designed for export market. Despite not being operated by the German Navy, five variants of the class (209/1100, 209/1200, 209/1300, 209/1400 and 209/1500) have been successfully exported to 13 countries, with 61 submarines being built and commissioned between 1971 and 2008. Development In the early 1970s, many navies began to need replacements for World War II-era submarines, aging United States GUPPY conversions, and British units transferred postwar. During this time, few western submarine designs were available for export as most were large, expensive, sophisticated and difficult to operate, and designed for the Cold War. Several designs originally built for specific nations were available including the French , British , and the Soviet subma ...

Second Strike
In nuclear strategy, a retaliatory strike or second-strike capability is a country's assured ability to respond to a nuclear attack with powerful nuclear retaliation against the attacker. To have such an ability (and to convince an opponent of its viability) is considered vital in nuclear deterrence, as otherwise the other side might attempt to try to win a nuclear war in one massive first strike against its opponent's own nuclear forces. Theory The possession of second-strike capabilities counters a first-strike nuclear threat and can support a no first use nuclear strategy. Reciprocal second-strike capabilities usually cause a mutual assured destruction defence strategy, though one side may have a lower level minimal deterrence response. Second-strike capabilities can be further strengthened by implementing fail-deadly mechanisms. These mechanisms create a threshold and guaranteed consequences if that threshold is breached. For instance, a threshold may be for an allied na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunday Times
''The Sunday Times'' is a British newspaper whose circulation makes it the largest in Britain's quality press market category. It was founded in 1821 as ''The New Observer''. It is published by Times Newspapers Ltd, a subsidiary of News UK, which is owned by News Corp. Times Newspapers also publishes ''The Times''. The two papers were founded independently and have been under common ownership since 1966. They were bought by News International in 1981. ''The Sunday Times'' has a circulation of just over 650,000, which exceeds that of its main rivals, including ''The'' ''Sunday Telegraph'' and ''The'' ''Observer'', combined. While some other national newspapers moved to a tabloid format in the early 2000s, ''The Sunday Times'' has retained the larger broadsheet format and has said that it would continue to do so. As of December 2019, it sells 75% more copies than its sister paper, ''The Times'', which is published from Monday to Saturday. The paper publishes ''The Sunday ...

Plutonium
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthetically produced and isolated in late 1940 and early 1941, by a deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 ( half-life 2.1 days) was synthesized, which subsequently beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Since ...

Nuclear Warhead
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deploy ...

Submarine-launched Cruise Missile
A submarine-launched cruise missile (SLCM) is a cruise missile that is launched from a submarine (especially a SSG or SSGN). Current versions are typically standoff weapons known as land-attack cruise missiles (LACMs), which are used to attack predetermined land targets with conventional or nuclear payloads. Anti-ship cruise missiles (ASCMs) are also used, and some submarine-launched cruise missiles have variants for both functions. History of development The U.S. Navy's first land-attack cruise missile submarines (4 SSG and 1 SSGN) deployed with the Regulus missile from 1958 until retired in 1964 with the arrival of the Polaris ballistic missile submarines (SSBNs) in the Pacific. The US deployed the short-range Harpoon anti-ship missile on submarines beginning in 1981. The Soviet Navy converted 13 Whiskey-class submarines (Project 613) for the land-attack cruise missile (LACM) role in the late 1950s (Whiskey Single Cylinder, Whiskey Twin Cylinder, Whiskey Long Bin), arme ...

Popeye (missile)
Popeye (Hebrew: פופאי) is a family of air-to-surface missiles developed and in use by Israel, of which several types have been developed for Israeli and export users. A long-range submarine-launched cruise missile variant of the Popeye Turbo has been speculated as being employed in Israel's submarine-based nuclear forces.Israeli missile FAS The United States operated the Popeye under a different designation according to US naming conventions as the AGM-142 Have Nap. Design The Popeye is designed for precision attack against large targets from stand off ranges. The standard Popeye and smaller Popeye-Lite are powered by a single-stage[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/ submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though ...

Israel Defense Forces
The Israel Defense Forces (IDF; he, צְבָא הַהֲגָנָה לְיִשְׂרָאֵל , ), alternatively referred to by the Hebrew-language acronym (), is the national military of the Israel, State of Israel. It consists of three service branches: the Israeli Ground Forces, the Israeli Air Force, and the Israeli Navy. It is the sole military wing of the Israeli security forces, Israeli security apparatus, and has no civilian jurisdiction within Israel. The IDF is headed by the Chief of the General Staff (Israel), Chief of the General Staff, who is subordinate to the Ministry of Defense (Israel), Israeli Defense Minister. On the orders of David Ben-Gurion, the IDF was formed on 26 May 1948 and began to operate as a Conscription in Israel, conscript military, drawing its initial recruits from the already-existing paramilitaries of the Yishuv—namely Haganah, the Irgun, and Lehi (militant group), Lehi.

Type 214
The Type 214 is a diesel-electric submarine developed by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class is exclusively designed for export market. The submarine class combines the design principles of the Type 209 family and the features of the Type 212A submarines. However, as an export design, it lacks some of the classified technologies of the smaller Type 212, the most important of which is probably the non-magnetic steel hull, which makes the Type 212 submarine difficult to detect using a magnetic anomaly detector. Due to improvements in the pressure hull materials, the Type 214 can dive nearly . It can also carry food, fresh water and fuel for 84 days of operation. A contract to build four boats for the Hellenic Navy was signed 15 February 2000 and a fourth unit was ordered in June 2002. The first boat was built ...
