FGM-148
The FGM-148 Javelin, or Advanced Anti-Tank Weapon System-Medium (AAWS-M), is an American-made portable anti-tank missile system in service since 1996, and continuously upgraded. It replaced the M47 Dragon anti-tank missile in US service. Its fire-and-forget design uses automatic infrared guidance that allows the user to seek cover immediately after launch, in contrast to wire-guided systems, like the system used by the Dragon, which require a user to guide the weapon throughout the engagement. The Javelin's high-explosive anti-tank (HEAT) warhead can defeat modern tanks by top attack, hitting them from above, where their armor is thinnest, and is also useful against fortifications in a direct attack flight. , the Javelin had been used in around 5,000 successful engagements. Overview Javelin is a fire-and-forget missile with lock-on before launch and automatic self-guidance. The system takes a top attack flight profile against armored vehicles, attacking the usually thinner top arm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M47 Dragon
The M47 Dragon, known as the FGM-77 during development, is an American shoulder-fired, man-portable anti-tank guided missile system. It was phased out of U.S. military service in 2001, in favor of the newer FGM-148 Javelin system. The M47 Dragon uses a wire-guidance system in concert with a high explosive anti-tank warhead and was capable of defeating armored vehicles, fortified bunkers, main battle tanks, and other hardened targets. While it was primarily created to defeat the Soviet Union's T-55, T-62, and T-72 tanks, it saw use well into the 1990s, seeing action in the Persian Gulf War. The U.S. military officially retired the weapon in 2001. The United States destroyed the last of its stocks of the missile in 2009. The weapon system remains in active service with other militaries around the world. History In 1959, the US Army Ordnance Missile Command suggested the development of a heavy medium range assault weapon. In 1960, the United States Army launched the MAW (Mediu ...

Anti-tank Missile
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a Missile guidance, guided missile primarily designed to hit and destroy Armoured fighting vehicle, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandem Warhead
A tandem-charge or dual-charge weapon is an explosive device or projectile that has two or more stages of detonation, assisting it to penetrate either reactive armour on an armoured vehicle or strong structures. Anti-tank Tandem charges are effective against reactive armour, which is designed to protect an armoured vehicle (mostly tanks) against anti-tank munitions. The first stage of the weapon is typically a weak charge that either pierces the reactive armour of the target without detonating it, leaving a channel through the reactive armour so that the second warhead may pass unimpeded, or simply detonates the armour, causing the timing of the counter-explosion to fail. The second detonation from the same projectile (which defines it as a tandem charge) attacks the same location as the first detonation where the reactive armour has been compromised. Since the regular armour plating is often the only defence remaining, the main charge (second detonation) has an increased likel ...

Top Attack
Plunging fire is a form of indirect fire, where gunfire is fired at a trajectory to make it fall on its target from above. It is normal at the high trajectories used to attain long range, and can be used deliberately to attack a target not susceptible to direct or grazing fire due to not being in direct line of sight. In naval warfare, plunging shellfire was theoretically capable of penetrating an enemy ship's thinner deck armor rather than firing directly at a warship's heavily armored side. Plunging fire in terrestrial warfare allows attacking a target not in direct line of sight, for example over the brow of a hill engaging in a reverse slope defence. Artillery weapons such as howitzers and mortars are designed for this purpose. Machine guns and belt-fed grenade launchers may also use plunging fire. A top attack weapon is designed to attack armoured vehicles from above as a form of plunging fire, as the armour is usually thinnest on the top of the vehicle. Ideally, it will p ...

Man-portable Anti-tank Systems
Man-portable anti-tank systems (MANPATS or MPATS) are traditionally portable shoulder-launched projectile systems firing heavy shell-type projectiles (although throwing and lunge weapons have existed), typically designed to combat protected targets, such as armoured vehicles, field fortifications and at times even low-flying aircraft (especially helicopters). MPATS-launchers can be either unguided or guided weapons and generally fall into three distinct categories: *''Disposable systems'', consisting of a small pre-loaded, single-shot launch tube meant to be disposed after firing, operated by one soldier. Examples include: Panzerfaust 1, M72 LAW, Miniman, AT4, FGM-148 Javelin, NLAW, etc. *''Reusable systems'', consisting of a reloadable firing system onto/into which a rocket or cartridge is loaded, operated by one or two soldiers. Examples include: Bazooka, Panzerschreck, Carl Gustaf 8.4 cm recoilless rifle, RPG-7, Panzerfaust 2, etc. *''Semi-disposable systems'', where the launch ...

Martin Marietta
The Martin Marietta Corporation was an American company founded in 1961 through the merger of Glenn L. Martin Company and American-Marietta Corporation. In 1995, it merged with Lockheed Corporation to form Lockheed Martin. History Martin Marietta formed in 1961 by the merger of the Glenn L. Martin Company and American-Marietta Corporation. Martin, based in Baltimore, was primarily an aerospace concern with a recent focus on missiles, namely its Titan program. American-Marietta was headquartered in Chicago and produced paints, dyes, metallurgical products, construction materials, and other goods. In 1982, Martin Marietta was subject to a hostile takeover bid by the Bendix Corporation, headed by William Agee. Bendix bought the majority of Martin Marietta shares and in effect owned the company. However, Martin Marietta's management used the short time separating ownership and control to sell non-core businesses and launch its own hostile takeover of Bendix (known as the Pac-Ma ...

Fire-and-forget
Fire-and-forget is a type of missile guidance which does not require further external intervention after launch such as illumination of the target or wire guidance, and can hit its target without the launcher being in line-of-sight of the target. This is an important property for a guided weapon to have, since a person or vehicle that lingers near the target to guide the missile (using, for instance, a laser designator) is vulnerable to attack and unable to carry out other tasks. Generally, information about the target is programmed into the missile just prior to launch. This can include coordinates, radar measurements (including velocity), or an infrared image of the target. After it is fired, the missile guides itself by some combination of gyroscopes and accelerometers, GPS, onboard active radar homing, and infrared homing optics. Some systems offer the option of either continued input from the launch platform or fire-and-forget. Fire-and-forget missiles can be vulnerable ...

Imaging Infrared
Infrared thermography (IRT), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become ea ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...
