TROPHY Active Protection System
Trophy (Israel Defense Forces designation מעיל רוח, lit. "Windbreaker") is a military active protection system (APS) designed to protect vehicles from anti-tank guided missiles (ATGMs), rocket-propelled grenades (RPGs), anti-tank rockets, and high-explosive anti-tank (HEAT) rounds. A small number of explosively formed projectiles destroy incoming threats before they hit the vehicle. Its principal purpose is to supplement the armour of light and heavy armored fighting vehicles. Developed by Rafael Advanced Defense Systems Ltd. of Israel and currently fielding over 1,000 systems to all major Israeli ground combat platforms (Merkava Mark 3 & 4 and Namer APCs), and U.S. Abrams M1A1/2, and tested on the Stryker APCs and Bradley Fighting Vehicles (BFVs). Trophy protects against a wide variety of anti-tank threats, while also maximizing the vehicle's ability to identify enemy location to crews and combat formation, thereby providing greater survivability and maneuverability in ...

AESA Radar
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matrix i ...

Abrams M1A1
The M1 Abrams is a List of main battle tanks by generation, third-generation American main battle tank designed by Chrysler Defense (now General Dynamics Land Systems) and named for General Creighton Abrams. Conceived for modern Armoured warfare, armored ground warfare and now one of the heaviest tanks in service at nearly 68 short tons (almost 62 tonne, metric tons), it introduced several modern technologies to US armored forces, including a multifuel gas turbine, turbine engine, sophisticated Chobham armour, Chobham composite armor, a computer fire control system, separate ammunition storage in a blow-out compartment, and Weapon of mass destruction, NBC protection for crew safety. Initial models of the M1 were armed with a licensed-produced 105 mm Royal Ordnance L7 gun, while later variants feature a licensed Rheinmetall Rh-120, Rheinmetall 120 mm L/44. The M1 Abrams was developed from the failure of the MBT-70 project to replace the obsolescent M60 tank. There are three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9M133 Kornet
The 9M133 Kornet (russian: Корнет; "Cornet", NATO reporting name AT-14 Spriggan, export designation Kornet-E) is a Russian man-portable anti-tank guided missile (ATGM) intended for use against main battle tanks. It was first introduced into service with the Russian army in 1998. The Kornet is among the most capable Russian ATGMs. It is not intended to fully replace previous systems, due to its high cost. It was further developed into the 9M133 Kornet-EM, which has increased range, and an improved warhead. The Kornet has been widely exported and is produced under license in several countries. It was first used in combat in 2003 and has since been used in many conflicts. Development The Kornet anti-tank missile was unveiled in October 1994 by the KBP Instrument Design Bureau. The missile started development in 1988 as a modular, universal system able to engage any target from a mix of platforms using a reliable laser beam guidance system that was simple to use. It is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armored 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 armament and are not designed to provide direct fire support in battle. Infantry units which travel in APCs are known as mechanized infantry. Some militaries also make a distinction between infantry units which use APCs and infantry units which use IFVs, with the latter being known as armoured infantry in such militaries.

Kinetic Energy Penetrator
A kinetic energy penetrator (KEP), also known as long-rod penetrator (LRP), is a type of ammunition designed to penetrate vehicle armour using a flechette-like, high-sectional density projectile. Like a bullet or kinetic energy weapon, this type of ammunition does not contain explosive payloads and uses purely kinetic energy to penetrate the target. Modern KEP munitions are typically of the armour-piercing fin-stabilized discarding sabot (APFSDS) type. History Early cannons fired kinetic energy ammunition, initially consisting of heavy balls of worked stone and later of dense metals. From the beginning, combining high muzzle energy with projectile weight and hardness have been the foremost factors in the design of such weapons. Similarly, the foremost purpose of such weapons has generally been to defeat protective shells of armored vehicles or other defensive structures, whether it is stone walls, sailship timbers, or modern tank armour. Kinetic energy ammunition, in its vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Propelled Grenade
A rocket-propelled grenade (RPG) is a shoulder-fired missile weapon that launches rockets equipped with an explosive warhead. Most RPGs can be carried by an individual soldier, and are frequently used as anti-tank weapons. These warheads are affixed to a rocket motor which propels the RPG towards the target and they are stabilized in flight with fins. Some types of RPG are reloadable with new rocket-propelled grenades, while others are single-use. RPGs are generally loaded from the front. RPGs with high-explosive anti-tank (HEAT) warheads are very effective against lightly armored vehicles such as armored personnel carriers (APCs) and armored cars. However, modern, heavily-armored vehicles, such as upgraded APCs and main battle tanks, are generally too well-protected (with thick composite or reactive armor) to be penetrated by an RPG, unless less armored sections of the vehicle are exploited. Various warheads are also capable of causing secondary damage to vulnerable syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command And Control
Command and control (abbr. C2) is a "set of organizational and technical attributes and processes ... hatemploys human, physical, and information resources to solve problems and accomplish missions" to achieve the goals of an organization or enterprise, according to a 2015 definition by military scientists Marius Vassiliou, David S. Alberts, and Jonathan R. Agre. The term often refers to a military system. Versions of the United States Army ''Field Manual 3-0'' circulated circa 1999 define C2 in a military organization as the exercise of authority and direction by a properly designated commanding officer over assigned and attached forces in the accomplishment of a mission. A 1988 NATO definition is that command and control is the exercise of authority and direction by a properly designated individual over assigned resources in the accomplishment of a common goal. An Australian Defence Force definition, similar to that of NATO, emphasises that C2 is the system empowering de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Countermeasure
A countermeasure is a measure or action taken to counter or offset another one. As a general concept, it implies precision and is any technological or tactical solution or system designed to prevent an undesirable outcome in the process. The first known use of the term was in 1923. "Countermeasure" defined Countermeasures can refer to the following disciplinary spectrum: * Medicine * Materials engineering * Electro-magnetic engineering * Policing * Information technology * * Diplomatic security * Pollution prevention * Aviation Defense countermeasures are often divided into ...

Explosively Formed Penetrator
An explosively formed penetrator (EFP), also known as an explosively formed projectile (EFP), a self-forging warhead, or a self-forging fragment, is the product of a shaped charge designed to penetrate armor effectively. As the name suggests, the effect of the explosive charge is to deform a metal plate into a jet, slug or rod shape and accelerate it toward a target. They were first developed as oil well perforators by American oil companies in the 1930s, and were deployed as weapons in World War II. Difference from conventional shaped charges A shaped charge generally has a metal liner that is forced by an explosive blast into a metal jet or slug able to penetrate thick steel armor and knock out vehicles. A disadvantage of this arrangement is that the jet of metal loses effectiveness the further it travels, as it breaks up into disconnected particles that drift out of alignment. An EFP operates on the principle designed to form a distinct projectile (slug or jet), permittin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-control Radar
A fire-control radar (FCR) is a radar that is designed specifically to provide information (mainly target azimuth, elevation, range and range rate) to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as targeting radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar. A typical fire-control radar emits a narrow, intense beam of radio waves to ensure accurate tracking information and to minimize the chance of losing track of the target. This makes them less suitable for initial detection of the target, and FCRs are often partnered with a medium-range search radar to fill this role. In British terminology, these medium-range systems were known as tactical control radars. Most modern radars have a track-while-scan capability, enabling them to function simultaneously as both fire-control radar and search radar. This works either by having t ...
