Armored Vehicle
Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships. Civilian vehicles may also be armoured. These vehicles include cars used by officials (e.g., presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the hijacking of the cargo. Armour may also be used in vehicles to protect from threats other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against impacts from micrometeoroids or fragments of space debris. Modern aircraft powered by jet engines usually have them fitted with a sort of armour in the form of an aramid composite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bunker
A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes. Trench bunkers are small concrete structures, partly dug into the ground. Many artillery installations, especially for coastal artillery, have historically been protected by extensive bunker systems. Typical industrial bunkers include mining sites, food storage areas, dumps for materials, data storage, and sometimes living quarters. When a house is purpose-built with a bunker, the normal location is a reinforced below-ground bathroom with fiber-reinforced plastic shells. Bunkers deflect the blast wave from nearby explosions to prevent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missile
In military terminology, a missile is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still ...

Joint Common Missile
The AGM-169 Joint Common Missile (JCM) was a tactical air-to-surface missile program (2002–2007) developed by the Lockheed Martin corporation for the United States military aircraft, such as attack and utility helicopters, strike fighters and fighter-bombers. Overview The missile was designed to replace the AGM-114 Hellfire and AGM-65 Maverick. Its seeker head used a combination of semi-active laser, millimeter wave, and IR guidance similar to that found on the FGM-148 Javelin anti-tank missile. This allows the missile to have a greater fire and forget capability and to operate off all current air platforms. The missile has longer range, a more potent warhead, and a "safing" system, allowing naval aircraft to return to ship without jettisoning the munitions. This missile also shares similarities to the MBDA Brimstone missile. Development Originally known as CMM (Common Modular Missile), the JCM (Joint Common Missile) was to be also a replacement for the BGM-71 TOW, but ...

Precision Attack Missile
The Non-Line of Sight Launch System (NLOS-LS) was a self-contained missile launcher system that was under development by NETFIRES LLC, a partnership between Lockheed Martin and Raytheon. Each Container Launch Unit (CLU) holds 15 missiles, and a self-locating networked communications system. CLUs can be linked for coordinated launching, with the missiles fired and controlled remotely via autonomous vertical launch. The weapon is roughly 2 metres tall. The program was cancelled early 2011. It was being developed for the United States Navy's Littoral Combat Ship, but has been criticised for performance issues. The Griffin missile has been recommended for use instead. NLOS-LS was to be used primarily on the United States Army's Future Combat Systems before it was canceled. Concept There were to be two types of missile used with NLOS-LS: the Precision Attack Munition (PAM) and the Loitering Attack Munition (LAM). The LAM was originally contracted to Lockheed Martin Missiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AH-64 Apache
The Boeing AH-64 Apache () is an American twin-turboshaft attack helicopter with a tailwheel-type landing gear arrangement and a tandem cockpit for a crew of two. It features a nose-mounted sensor suite for target acquisition and night vision systems. It is armed with a M230 chain gun carried between the main landing gear, under the aircraft's forward fuselage, and four hardpoints mounted on stub-wing pylons for carrying armament and stores, typically a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods. The AH-64 has significant systems redundancy to improve combat survivability. The Apache began as the ''Model 77'' developed by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the AH-1 Cobra. The prototype YAH-64 was first flown on 30 September 1975. The U.S. Army selected the YAH-64 over the Bell YAH-63 in 1976, and later approved full production in 1982. After purchasing Hughes Helicopters in 1984, McDonnell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AH-1 Super Cobra
The Bell AH-1 SuperCobra is a twin-engined attack helicopter that was developed on behalf of, and primarily operated by, the United States Marine Corps (USMC). The twin Cobra family, itself part of the larger Huey family, includes the AH-1J SeaCobra, the AH-1T Improved SeaCobra, and the AH-1W SuperCobra. The Super Cobra was derived from the single-engined AH-1 Cobra, which had been developed during the mid-1960s as an interim gunship for the U.S. Army. The USMC had quickly taken an interest in the type, but sought a twin-engined arrangement for greater operational safety at sea, along with more capable armaments. While initially opposed by the Department of Defense, who were keen to promote commonality across the services, in May 1968, an order for an initial 49 twin-engine AH-1J SeaCobras was issued to Bell. The type entered service during the final months of the US's involvement in the Vietnam War, seeing limited action in the theatre as a result. The USMC promptly sought ...

MH-60 Pave Hawk
The Sikorsky MH-60G/HH-60G Pave Hawk is a four-blade, twin-engine, medium-lift Utility helicopter, utility military helicopter manufactured by Sikorsky Aircraft. It is a derivative of the Sikorsky UH-60 Black Hawk, UH-60 Black Hawk and incorporates the US Air Force PAVE electronic systems program. The HH-60/MH-60 is a member of the Sikorsky S-70 family. The MH-60G Pave Hawk's primary mission is insertion and recovery of special operations personnel, while the HH-60G Pave Hawk's core mission is recovery of personnel under hostile conditions, including combat search and rescue. Both versions conduct day or night operations into hostile environments. Because of its versatility, the HH-60G may also perform peacetime operations such as civil search and rescue, emergency medical evacuation, aeromedical evacuation (MEDEVAC), disaster relief, international aid and counter-drug activities. Design and development In 1981, the U.S. Air Force chose the Sikorsky UH-60 Black Hawk, UH-60A Bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millimeter Wave
Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band and the far infrared band, the lower part of which is the terahertz band. Radio waves in this band have wavelengths from ten to one millimetre, so it is also called the millimetre band and radiation in this band is called millimetre waves, sometimes abbreviated MMW or mmWave. Millimetre-length electromagnetic waves were first investigated by Indian physicist Jagadish Chandra Bose, who generated waves of frequency up to 60GHz during experiments in 18941896. Compared to lower bands, radio waves in this band have high atmospheric attenuation: they are absorbed by the gases in the atmosphere. Absorption increases with frequency until at the top end of the band the waves are attenuated to zero within a few meters. Absorption by humidity in the atmosp ...

Active Radar Homing
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a receiver) and the electronics necessary for it to find and track its target autonomously. The NATO brevity code for an air-to-air active radar homing missile launch is fox three. Advantages There are two major advantages to active radar homing: * As the missile is tracking the target it is going to be much closer to the target than the launching platform during the terminal phase, thus the missile's tracking can be much more accurate and better resistant to electronic countermeasures. Active radar homing missiles have some of the best kill probabilities, along with missiles employing track-via-missile guidance. * Because the missile is totally autonomous during the terminal phase, the launch platform does not need to have its radar enabled at all during this phase, and in the case of a mobile launching platform ...

Infrared Homing
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cuing system. Heat-seekers are extremely effective: 90% of all United States air combat losses over the past 25 years have been caused by infrared-homing missiles. They are, however, subject to a number of simple countermeasures, most notably by dropping flares beh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
