Compact Kinetic Energy Missile
The Compact Kinetic Energy Missile (CKEM) was a developmental program to produce a hypersonic anti-tank guided missile for the U.S. Army. Lockheed Martin was the primary contractor. The program was the third in a series of projects based on kinetic energy missiles that stretches back to 1981's Vought HVM through the 1990s to 2000s LOSAT and finally to the CKEM. The Army Aviation and Missile Command (AMCOM) developed this program as part of the Army's Future Combat Systems. This missile was primarily an anti-tank weapon, and could be mounted on land vehicles and low-altitude aircraft. The goal of these weapons was to demonstrate a state-of-the-art system for the next generation. The program has since been cancelled.

Hypersonic
In aerodynamics, a hypersonic speed is one that exceeds 5 times the speed of sound, often stated as starting at speeds of Mach 5 and above. The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at different speeds; these effects collectively become important around Mach 5-10. The hypersonic regime can also be alternatively defined as speeds where specific heat capacity changes with the temperature of the flow as kinetic energy of the moving object is converted into heat. Characteristics of flow While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow. The peculiarity in hypersonic flows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-tank Guided Missile
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 lig ...

Lockheed Martin
The Lockheed Martin Corporation is an American aerospace, arms, defense, information security, and technology corporation with worldwide interests. It was formed by the merger of Lockheed Corporation with Martin Marietta in March 1995. It is headquartered in North Bethesda, Maryland, in the Washington, D.C. area. Lockheed Martin employs approximately 115,000 employees worldwide, including about 60,000 engineers and scientists as of January 2022. Lockheed Martin is one of the largest companies in the aerospace, military support, security, and technologies industry.

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] |
Vought HVM
{{no footnotes, date=November 2015 Vought's HVM, short for Hyper-Velocity Missile, was an anti-tank missile developed during the 1980s. The HVM carried no warhead and killed its targets with kinetic energy alone using a metal rod penetrator. Development as an air-launched weapon for the A-10 Thunderbolt II ended sometime in the late 1980s but continued for helicopter use into the 1990s along with ground-launched (High Mobility Multipurpose Wheeled Vehicle, HMMWV) as the larger MGM-166 LOSAT. None of these systems was operationally deployed. The HVM was intended as a fairly inexpensive weapon, compared to the AGM-65 Maverick at least, offering the standoff performance while requiring a minimum of support electronics. The target was acquired using a FLIR system on the launch vehicle, and after launch the missile quickly accelerated to 1500 m/s (5,000 ft/s, 5,400 km/h, Mach 4.3) and into the view of the FLIR, which tracked both the target and missile from that point on.

LOSAT
The MGM-166 LOSAT (Line-of-Sight Anti-Tank) was a United States anti-tank missile system designed by Lockheed Martin (originally Vought) to defeat tank A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engin ...s and other individual targets. Instead of using a High-explosive anti-tank, high explosive anti-tank (HEAT) warhead like other anti-tank missiles, LOSAT employed a solid steel kinetic energy penetrator to punch through armor. The LOSAT is fairly light; it was designed to be mounted onto a Humvee light military vehicle while allowing the vehicle to remain air-portable. LOSAT eventually emerged on an extended-length heavy-duty Humvee with a hard-top containing four KEMs used by special operations. Although LOSAT never "officially" entered service, it was used for the smaller Compact K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
