Merkava Tank
The Merkava (, , "chariot") is a series of main battle tanks used by the Israel Defense Forces (IDF) which are the backbone of the IDF's Armored Corps. Current iterations of this tank are considered broadly equivalent to the capabilities of the M1 Abrams, Leopard 2 and the Challenger 2. The current Merkava uses the same MTU EuroPowerPack powerplant as a number of other tanks. Development began in 1970, and its first generation, the Merkava Mark 1, entered official service in 1979. Four main variants have been deployed. As of 2023, Merkava Mark 4 Barak is the latest version. The Merkava was first used extensively in the 1982 Lebanon War. The name "Merkava" was derived from the IDF's initial development program name. The tank was developed in the Merkava and Armored Combat Vehicles Division of the Israeli Ministry of Defense, and most of its parts are manufactured in Israel. The Merkava was designed to provide maximum protection for its crew, and therefore its front armor was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trophy (countermeasure)
Trophy (Israel Defense Forces designation ) is a protection system for military armored vehicles. It is termed an active protection system (APS) and is designed by Rafael Advanced Defense Systems. It is designed to supplement the standard armor of light and heavy armored fighting vehicles. The system is in active use on Merkava Mark 3 & 4 tanks and the Namer armored personnel carrier (APC). It is also found on the Abrams M1A1/2 tanks, and has been tested on Stryker APCs and Bradley Fighting Vehicles. The Trophy system protects against a wide variety of anti-tank threats, while also enhancing the vehicle's ability to identify enemy locations. Design Trophy's first production manufacturing contract between IDF and Rafael was signed in 2007. Israeli Government/IDF Safety certification was granted in 2010. First deliveries began immediately afterward. The design is centered on the Elta Systems, Elta EL/M-2133 F band (NATO), F/G band (NATO), G band fire-control radar with four f ...

ATGM
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank weapons, like anti-tank rifles and magnetic anti-tank mines, generally had very short range, sometimes on the order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote wire guidance that made the ATGM much more effective than these earlier weapons, and gave ...

Israel Defense Forces
The Israel Defense Forces (IDF; , ), alternatively referred to by the Hebrew-language acronym (), is the national military of the 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. 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), defense minister. On the orders of first prime minister 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. It was formed shortly after the Israeli Declaration of Independence and has participated in List of wars involving Israel, every armed conflict involving Israel. In the wak ...

Main Battle Tank
A main battle tank (MBT), also known as a battle tank or universal tank or simply tank,Ogorkiewicz 2018 p222 is a tank that fills the role of armour-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter composite armour allowed for the design of a tank that had the firepower of a super-heavy tank, the armour protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. The first ''designated'' MBT was the British Chieftain (tank), Chieftain tank, which during its development in the 1950s was re-designed as an MBT. Throughout the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armoured fighting vehicles.

Chariot
A chariot is a type of vehicle similar to a cart, driven by a charioteer, usually using horses to provide rapid Propulsion, motive power. The oldest known chariots have been found in burials of the Sintashta culture in modern-day Chelyabinsk Oblast, Russia, dated to c. 1950–1880 BC and are depicted on cylinder seals from Central Anatolia Region, Central Anatolia in Kültepe dated to c. 1900 BC. The critical invention that allowed the construction of light, horse-drawn chariots was the spoked wheel. The chariot was a fast, light, open, two-wheeled conveyance drawn by two or more Equidae, equids (usually horses) that were hitched side by side, and was little more than a floor with a waist-high guard at the front and sides. It was initially used for ancient warfare during the Bronze Age, Bronze and Iron Age, Iron Ages, but after its military capabilities had been superseded by Light cavalry, light and Heavy cavalry, heavy cavalries, chariots continued to be used for travel and t ...

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Turbocharger
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.

MTU Friedrichshafen
MTU Friedrichshafen GmbH, trading as MTU Solutions (stylised as mtu Solutions) is a German manufacturer of commercial internal combustion engines founded by Wilhelm Maybach and his son Karl Maybach in 1909. Wilhelm Maybach was the technical director of Daimler-Motoren-Gesellschaft (DMG), a predecessor company of the German multinational automotive corporation Daimler AG, until he left in 1907. On 23 March 1909, he founded the new company, Luftfahrzeug-Motorenbau GmbH (Aircraft Engine Manufacturing Corp), with his son Karl Maybach as director. A few years later the company was renamed to Maybach-Motorenbau GmbH (Maybach Engine Manufacturing Corp), which originally developed and manufactured diesel and petrol engines for Zeppelins, and then railcars. The Maybach Mb.IVa was used in aircraft and airships of World War I. The company first built an experimental car in 1919, with the first production model introduced two years later at the Berlin Motor Show. Between 1921 and 1940, t ...

Sloped Armour
Sloped armour is armour that is oriented neither Vertical and horizontal, vertically nor horizontally. Such angled armour is typically mounted on tanks and other armoured fighting vehicles (AFVs), as well as Naval ship, naval vessels such as battleships and cruisers. Sloping an armour plate makes it more difficult to penetrate by anti-tank weapons, such as Armour-piercing shell, armour-piercing shells, kinetic energy penetrators and Rocket (weapon), rockets, if they follow a more or less horizontal trajectory to their target, as is often the case. The improved protection is caused by three main effects. Firstly, a projectile hitting a plate at an angle other than 90° has to move through a greater thickness of armour, compared to hitting the same plate at a right-angle. In the latter case only the plate thickness (the surface normal, normal to the surface of the armour) must be pierced. Increasing the armour slope improves, for a given plate thickness, the level of protection at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Composite Armour
Composite armour is a type of vehicle armour consisting of layers of different materials such as metals, plastics, ceramics or air. Most composite armours are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It is possible to design composite armour stronger, lighter and less voluminous than traditional armour, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle. Its primary purpose is to help defeat high-explosive anti-tank (HEAT) projectiles. HEAT had posed a serious threat to armoured vehicles since its introduction in World War II. Lightweight and small, HEAT projectiles could nevertheless penetrate hundreds of millimetres of the most resistant rolled homogeneous armour, steel armours. The capability of most materials for defeating HEAT follows the "density law", which states that the penetration of shaped charge jets is proportional to the square root of t ...

Smoke Grenade
A smoke grenade is a canister-type grenade used as a signaling device, target or landing zone marking device, or as a screening device for unit movements. Smoke grenades are generally more complex and emit a far larger amount of smoke than smoke bombs, which are a type of firework typically started with an external fuse rather than a pin. Smoke grenades often cost around compared to smoke bombs, which can often cost just a few cents. The phrase "to smoke", meaning to fake, bluff, or beat around the bush, comes from the military usage of smoke grenades to obscure and conceal movement; similarly, "pop smoke", derived from a common way of ordering the use of smoke grenades, is used as a slang term for quickly leaving a place. __TOC__ Design left, Diagram and cross section of an M18 smoke grenade A typical design consists of a sheet steel cylinder with four emission holes on top and one on the bottom to allow smoke release when the grenade is ignited.
