Dakar-class Submarine
The ''Dakar''-class submarine (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). The ''Dakar'' class features a new design compared to the Israeli Navy's currently-serving s. It has been customized to fulfill the operational requirements of the Israeli Navy. The class was named in honor of , an Israeli submarine which mysteriously sank in 1968. In January 2022, Israel's Ministry of Defense 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 the operational requirements of the Israeli Navy.

Special Operations
Special operations (S.O.) are military activities conducted, according to NATO, by "specially designated, organized, selected, trained, and equipped forces using unconventional techniques and modes of employment". Special operations may include reconnaissance, unconventional warfare, and counter-terrorism actions, and are typically conducted by small groups of highly-trained personnel, emphasizing sufficiency, stealth, speed, and tactical coordination, commonly known as " special forces". History Australia In World War II following advice from the British, Australia began raising special forces. The first units to be formed were independent companies, which began training at Wilson's Promontory in Victoria in early 1941 under the tutelage of British instructors. With an establishment of 17 officers and 256 men, the independent companies were trained as "stay behind" forces, a role that they were later employed in against the Japanese in the South West Pacific Area during 1942†...

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapon
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 d ...

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), armed wi ...

Vertical Launching System
A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of ''cells'', which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up far enough to clear the cell and the ship, then turns on to the desired course. A VLS allows surface combatants to have a greater number of weapons ready for firing at any given time compared to older launching systems such as the Mark 13 single-arm and Mark 26 twin-arm launchers, which were fed from behind by a ...

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...

Type 216 Submarine
The Type 216 is a submarine design concept announced by Howaldtswerke-Deutsche Werft based on the Type 212/ 214. Development The design is double hulled with two decks, includes a fuel cell, Permasyn motor, and lithium-ion batteries. It is a larger design targeted to meet the needs of the Australian ''Collins''-class submarine replacement project, lso known as SEA 1000, and the needs of other countries possibly including India and Canada. The Royal Australian Navy eventually chose the Shortfin Barracuda, a conventional variant of the French Barracuda-class submarine and no Type 216 was put in production, though this deal was later rescinded. Successor The AIP-equipped Type 218SG of the Republic of Singapore Navy is a modified design based on the Type 216.. Five submarines were ordered by the Republic of Singapore Navy and the lead vessel RSS ''Invincible'' was launched in February 2019, followed by two more launched on 13 December 2022, with another two more under construc ...

Invincible-class Submarine
The ''Invincible''-class submarines, formally classified as the Type 218SG submarines, is a class of conventionally-powered attack submarines, ordered by the Republic of Singapore Navy (RSN) from German-based naval conglomerate ThyssenKrupp Marine Systems (TKMS). The Type 218SG is an extensively-customised derivative of the export-oriented Type 214 submarine, with specific design characteristics drawn from Type 212 submarines. They feature several capabilities - including a substantial level of automation, a significant payload capacity, enhanced underwater endurance and superlative ergonomics. Singapore's Ministry of Defense (MINDEF) ordered four Type 218SG submarines - two in 2013 and two in 2017, as a replacement to the RSN's currently-serving and submarines. The first submarine - RSS ''Invincible'', was launched in February 2019, and is expected to be commissioned by 2022. The RSN plans to have all four submarines in active service by 2024.

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...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] |
Intelligence, Surveillance, Target Acquisition, And Reconnaissance
ISTAR stands for intelligence, surveillance, target acquisition, and reconnaissance. In its macroscopic sense, ISTAR is a practice that links several battlefield functions together to assist a combat force in employing its sensors and managing the information they gather. Information is collected on the battlefield through systematic observation by deployed soldiers and a variety of electronic sensors. ''Surveillance'', ''target acquisition'' and ''reconnaissance'' are methods of obtaining this information. The information is then passed to intelligence personnel for analysis, and then to the commander and their staff for the formulation of battle plans. Intelligence is processed information that is relevant and contributes to an understanding of the ground, and of enemy dispositions and intents. Intelligence failures can happen. ISR (Intelligence, surveillance and reconnaissance) ISR is the coordinated and integrated acquisition, processing and provision of timely, accurat ...
