Terminal High Altitude Area Defense System
Terminal High Altitude Area Defense (THAAD), formerly Theater High Altitude Area Defense, is an American Anti-ballistic missile, anti-ballistic missile defense system designed to shoot down Short-range ballistic missile, short-, medium-range ballistic missile, medium-, and intermediate-range ballistic missile, intermediate-range ballistic missiles in their terminal phase (descent or reentry) by intercepting with a hit-to-kill approach. THAAD was developed after the experience of Iraq's Scud missile attacks during the Gulf War in 1991. The THAAD interceptor carries no warhead, instead relying on its kinetic energy of impact to destroy the incoming missile. Originally a United States Army program, THAAD has come under the umbrella of the Missile Defense Agency. The Navy has a similar program, the sea-based Aegis Ballistic Missile Defense System, which also has a land component ("Aegis Ashore"). THAAD was originally scheduled for deployment in 2012, but initial deployment took plac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-ballistic Missile
An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles (missile defense). Ballistic missiles are used to deliver nuclear, chemical, biological, or conventional warheads in a ballistic flight trajectory. The term "anti-ballistic missile" is a generic term conveying a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs). Current counter-ICBM systems There are a limited number of systems worldwide that can intercept intercontinental ballistic missiles: * The Russian A-135 anti-ballistic missile system (renamed in 2017 to A-235) is used for the defense of Moscow. It became operational in 1995 and was preceded by the A-35 anti-ballistic missile system. The system uses Gorgon and Gazelle missiles previously armed with nuclear warheads. These missiles have been updated (2017) and use non-nuclear kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aegis Ballistic Missile Defense System
The Aegis Ballistic Missile Defense System (Aegis BMD or ABMD), also known as ''Sea-Based Midcourse'', is a United States Department of Defense Missile Defense Agency program developed to provide missile defense against short to intermediate-range ballistic missiles. The program is part of the United States national missile defense strategy and European NATO missile defence system. Aegis BMD is an expansion of the Aegis Combat System deployed on warships, designed to intercept ballistic missiles in post-boost phase and prior to reentry. Aegis BMD-equipped vessels can engage potential threats using the Standard Missile 3 mid-course interceptors and the Standard Missile 2 and Standard Missile 6 terminal-phase interceptors.Aegis BMD web page , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infrared Countermeasure
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing ("heat seeking") missiles by confusing the missiles' infrared guidance system so that they miss their target (electronic countermeasure). Heat-seeking missiles were responsible for about 80% of air losses in Operation Desert Storm. The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile. An infrared sensor that is sensitive to heat, such as emitted from an aircraft engine, is included on missiles launched by man-portable air-defense systems (MANPADS). Using a steering system, the missile is programmed to home in on the infrared heat signal. Because they are portable, MANPADS missiles have a limited range, burning out a few seconds after launch. Countermeasure systems are usually integrated into the aircraft, such as in the fuselage, wing, or nose of the aircraft, or fixed to an outer po ...

Electrostatic Discharge
Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two electrically charged objects caused by contact, an electrical short or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark. ESD can create spectacular electric sparks (lightning, with the accompanying sound of thunder, is a large-scale ESD event), but also less dramatic forms which may be neither seen nor heard, yet still be large enough to cause damage to sensitive electronic devices. Electric sparks require a field strength above approximately 40 kV/cm in air, as notably occurs in lightning strikes. Other forms of ESD include corona discharge from sharp electrodes and brush discharge from blunt electrodes. ESD can cause harmful effects of importance in industry, inc ...

EM Pulse
An electromagnetic pulse (EMP), also a transient electromagnetic disturbance (TED), is a brief burst of electromagnetic energy. Depending upon the source, the origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a conducted electric current. The electromagnetic interference caused by an EMP disrupts communications and damages electronic equipment; at higher levels of energy, an EMP such as a lightning strike can physically damage objects such as buildings and aircraft. The management of EMP effects is a branch of electromagnetic compatibility (EMC) engineering. EMP weapons are designed to deliver the damaging effects of a high-energy EMP that will disrupt unprotected infrastructure in the country, thus the employment of an EMP weapon against a country is the scenario of war most likely to collapse the functionality of the electrical network of the country.

EM Radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum. Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields. Depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted ''c''. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The position of an electromagnetic wave within the electromagnetic spectrum can be characterized by either its f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EM Interference
Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. The disturbance may degrade the performance of the circuit or even stop it from functioning. In the case of a data path, these effects can range from an increase in error rate to a total loss of the data. Both man-made and natural sources generate changing electrical currents and voltages that can cause EMI: ignition systems, cellular network of mobile phones, lightning, solar flares, and auroras (northern/southern lights). EMI frequently affects AM radios. It can also affect mobile phones, FM radios, and televisions, as well as observations for radio astronomy and atmospheric science. EMI can be used intentionally for radio jamming, as in electronic warfare. History Since the earliest days of ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hera Missile
Hera is a target missile for development testing of missile defense systems such as Terminal High Altitude Area Defense and Patriot PAC-3. History In 1992, the United States Army Space and Missile Defense Command awarded the Theater Missile Defense (TMD) Targets contract to Coleman Aerospace with Space Vector and Aerotherm as sub-contractors. Coleman developed Hera using the second and third stages of the Minuteman II and the guidance section of the Pershing II. The Rocket Systems Launch Program at Detachment 12, USAF Space and Missile Systems Center, provided technical program management services involved with removing the liquid injection thrust vector control system from the retired MMII second stages in favor of a flex-seal system enabling robust flight control from launch to burn out. First launch was on April 24, 1995, at White Sands Missile Range. Because of its range, Russia claims Hera qualifies as an IRBM and hence violates Item 1, Article 6 of the INF Treaty. Her ...

White Sands Missile Range
White Sands Missile Range (WSMR) is a United States Army military testing area and firing range located in the US state of New Mexico. The range was originally established as the White Sands Proving Ground on 9July 1945. White Sands National Park is located within the range. Significant events *The first atomic bomb (code named Trinity) was test detonated at Trinity Site near the northern boundary of the range on 16 July 1945, seven days after the White Sands Proving Ground was established. *After the conclusion of World War II, 100 long-range German V-2 rockets that were captured by U.S. military troops were brought to WSMR. Of these, 67 were test-fired between 1946 and 1951 from the White Sands V-2 Launching Site. (This was followed by the testing of American rockets, which continues to this day, along with testing other technologies.) *NASA's Space Shuttle Columbia landed on the Northrop Strip at WSMR on 30 March 1982 as the conclusion to mission STS-3.

Lockheed Corporation
The Lockheed Corporation was an American aerospace manufacturer. Lockheed was founded in 1926 and later merged with Martin Marietta to form Lockheed Martin in 1995. Its founder, Allan Lockheed, had earlier founded the similarly named but otherwise-unrelated Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. History Origins Allan Loughead and his brother Malcolm Loughead had operated an earlier aircraft company, Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. The company built and operated aircraft for paying passengers on sightseeing tours in California and had developed a prototype for the civil market, but folded in 1920 due to the flood of surplus aircraft deflating the market after World War I. Allan went into the real estate market while Malcolm had meanwhile formed a successful company marketing brake systems for automobiles. On December 13, 1926, Allan Lockheed, John Northrop, Kenneth Kay and Fred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
