Namer
Namer (, ; meaning "leopard," and also a syllabic abbreviation of "Nagmash" (APC) and "Merkava") is an Israeli armoured personnel carrier based on a Merkava#Merkava Mark IV, Merkava Mark IV tank chassis. Namer was developed by and is being assembled by the Israeli Ordnance Corps. It has entered service in limited numbers with the Israel Defense Forces since the end of 2008. Due to budgetary constraints, the introduction of the Namer into the IDF has been slow, leaving the ground forces dependent on the M113 until 2027. History 1990s–2004 The experience of converting Centurion tanks into armoured personnel carriers (Nagmashot, Nagmachon) and combat engineering vehicles (Puma armored engineering vehicle, Puma, Nakpadon), followed by the conversion of many T-54/55, T-54 and T-55 tanks into IDF Achzarit, Achzarit infantry fighting vehicles, further promoted the idea of converting Merkava tanks into heavily armoured armoured personnel carrier, APCs / IFVs. This concept was also d ... [...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 ...

Armoured Personnel Carrier
An armoured personnel carrier (APC) is a broad type of armoured military vehicle designed to transport personnel and equipment in combat zones. Since World War I, APCs have become a very common piece of military equipment around the world. According to the definition in the Treaty on Conventional Armed Forces in Europe, an APC is "an armoured combat vehicle which is designed and equipped to transport a combat infantry squad and which, as a rule, is armed with an integral or organic weapon of less than 20 millimetres calibre." Compared to infantry fighting vehicles (IFVs), which are also used to carry infantry into battle, APCs have less weapon, armament and are not designed to provide direct fire support in battle. Infantry units that travel in APCs are known as mechanized infantry. Some militaries also make a distinction between infantry units that use APCs and infantry units that use IFVs, with the latter being known as armoured infantry.

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 ...

2014 Gaza War
The 2014 Gaza War, also known as Operation Protective Edge (, ), and Battle of the Withered Grain (), was a military operation launched by Israel on 8 July 2014 in the Gaza Strip, a Palestinian territory that has been governed by Hamas since 2007.Though Hamas governs the Gaza Strip, the majority of the international community (including the UN General Assembly, the United Nations Security Council, the European Union, the International Criminal Court, and many human rights organizations) consider Israel to be occupying Gaza, as it controls the region's airspace, coastline and most of its borders. Following the kidnapping and murder of three Israeli teenagers in the West Bank by Hamas-affiliated Palestinian militants, the Israel Defense Forces (IDF) initiated ''Operation Brother's Keeper'', in which it killed 10 Palestinians, injured 130 and imprisoned more than 600. Hamas reportedly did not retaliate but resumed rocket attacks on Israel more than two weeks later, following th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FN MAG
The FN MAG (, , ) is a Belgian 7.62 mm calibre, 7.62 mm general-purpose machine gun, designed in the early 1950s at Fabrique Nationale de Herstal, Fabrique Nationale (FN) by Ernest Vervier. It has been used by more than 80 countries and it has been made under licence in several countries, including Argentina, Canada (as the C6 GPMG), Egypt, India, and the United Kingdom.Hogg, Ian (2002).

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.

Sloped Armor
Sloped armour is armour that is oriented neither vertically nor horizontally. Such angled armour is typically mounted on tanks and other armoured fighting vehicles (AFVs), as well as 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 shells, kinetic energy penetrators and 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 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 the point of impact by increasing the thickness measured in the horizontal plane, the angl ...

Reactive Armour
Reactive armour is a type of vehicle armour used in protecting vehicles, especially modern tanks, against shaped charges and hardened kinetic energy penetrators. The most common type is ''explosive reactive armour'' (ERA), but variants include ''self-limiting explosive reactive armour'' (SLERA), ''non-energetic reactive armour'' (NERA), ''Non-explosive reactive armor, non-explosive reactive armour'' (NxRA), and electric armour. NERA and NxRA modules can withstand multiple hits, unlike ERA and SLERA. When a shaped charge strikes the upper plate of the armour, it detonates the inner explosive, releasing blunt damage that the tank can absorb. Reactive armour is intended to counteract anti-tank munitions that work by piercing the armour and then either killing the crew inside, disabling vital mechanical systems, or creating spalling that disables the crew—or all three. Reactive armour can be defeated with multiple hits in the same place, as by tandem-charge weapons, which fire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alloy
An alloy is a mixture of chemical elements of which in most cases at least one is a metal, metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described. Metallic alloys often have properties that differ from those of the pure elements from which they are made. The vast majority of metals used for commercial purposes are alloyed to improve their properties or behavior, such as increased strength, hardness or corrosion resistance. Metals may also be alloyed to reduce their overall cost, for instance alloys of gold and Copper(II) sulfate, copper. A typical example of an alloy is SAE 304 stainless steel, 304 grade stainless steel which is commonly used for kitchen utensils, pans, knives and forks. Sometime also known as 18/8, it as an alloy consisting broadly of 74% iron, 18% chromium and 8% nickel. The chromium and nickel alloying elements add strength and hardness to the majority iron element, but their main function is ...

Nickel
Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
