High Endoatmospheric Defense Interceptor (HEDI) was an atmospheric missile defense layer developed for the Strategic Defense Initiative, along with Exoatmospheric Reentry-vehicle Interceptor Subsystem. It consisted of a two-stage launch vehicle (booster) and an infrared homing kill vehicle with a conventional warhead. [1] Hughes Aircraft and Aerojet were contractors, and McDonnell Douglas was the system integrator. [1] [2]
The HEDI aimed to employ ground-based missiles to intercept submarine-launched ballistic missiles and intercontinental ballistic missiles and operate in the high endoatmosphere region in order to destroy them. [1]
An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles. 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 for 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).
The Aegis ballistic missile defense system, also known as Sea-Based Midcourse, is a Missile Defense Agency program under the United States Department of Defense developed to provide missile defense against short and intermediate-range ballistic missiles. The program is part of the United States national missile defense strategy and European NATO missile defense system.
National missile defense (NMD) refers to the nationwide antimissile program the United States has had under development since the 1990s. After the renaming in 2002, the term now refers to the entire program, not just the ground-based interceptors and associated facilities.
Ground-Based Midcourse Defense (GMD), previously National Missile Defense (NMD), is an anti-ballistic missile system implemented by the United States of America for defense against ballistic missiles, during the midcourse phase of ballistic trajectory flight. It is a major component of the American missile defense strategy to counter ballistic missiles, including intercontinental ballistic missiles (ICBMs) carrying nuclear, chemical, biological or conventional warheads.
Terminal High Altitude Area Defense (THAAD), formerly Theater High Altitude Area Defense, is an American anti-ballistic missile defense system designed to intercept and destroy short, medium, and intermediate-range ballistic missiles in their terminal phase. The THAAD interceptor carries no warhead, instead relying on its kinetic energy of impact to destroy the incoming missile. THAAD was developed after the experience of Iraq's Scud missile attacks during the Gulf War in 1991.
The Missile Defense Agency (MDA) is a component of the United States government's Department of Defense responsible for developing a comprehensive defense against ballistic missiles. It had its origins in the Strategic Defense Initiative (SDI) which was established in 1983 by Ronald Reagan and which was headed by Lt. General James Alan Abrahamson. Under the Strategic Defense Initiative's Innovative Sciences and Technology Office headed by physicist and engineer Dr. James Ionson, the investment was predominantly made in basic research at national laboratories, universities, and in industry. These programs have continued to be key sources of funding for top research scientists in the fields of high-energy physics, advanced materials, nuclear research, supercomputing/computation, and many other critical science and engineering disciplines—funding which indirectly supports other research work by top scientists, and which was most politically viable to fund from appropriations for national defense. It was renamed the Ballistic Missile Defense Organization in 1993, and then renamed the Missile Defense Agency in 2002. The current director is Lieutenant General Heath A. Collins.
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles. Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles.
The maneuverable reentry vehicle is a type of warhead for ballistic missiles that is capable of maneuvering and changing its trajectory.
Brilliant Pebbles was a ballistic missile defense (BMD) system proposed by Lowell Wood and Edward Teller of the Lawrence Livermore National Laboratory (LLNL) in 1987, near the end of the Cold War. The system would consist of thousands of small satellites, each with missiles similar to conventional heat seeking missiles, placed in low Earth orbit constellations so that hundreds would be above the Soviet Union at all times. If the Soviets launched their ICBM fleet, the pebbles would detect their rocket motors using infrared seekers and collide with them. Because the pebble strikes the ICBM before the latter could release its warheads, each pebble could destroy several warheads with one shot.
The Sprint was a two-stage, solid-fuel anti-ballistic missile (ABM), armed with a W66 enhanced-radiation thermonuclear warhead used by the United States Army during 1975–76. It was designed to intercept incoming reentry vehicles (RV) after they had descended below an altitude of about 60 kilometres (37 mi), where the thickening air stripped away any decoys or radar reflectors and exposed the RV to observation by radar. As the RV would be traveling at about 5 miles per second, Sprint needed to have phenomenal performance to achieve an interception in the few seconds before the RV reached its target.
The A-135 is a Russian anti-ballistic missile system deployed around Moscow to intercept incoming warheads targeting the city or its surrounding areas. The system was designed in the Soviet Union and entered service in 1995. It is a successor to the previous A-35, and complies with the 1972 Anti-Ballistic Missile Treaty.
Space Systems Command (SSC) is the United States Space Force's space development, acquisition, launch, and logistics field command. It is headquartered at Los Angeles Air Force Base, California, and manages the United States' space launch ranges.
The Indian Ballistic Missile Defence Programme is an initiative to develop and deploy a multi-layered ballistic missile defence system to protect India from ballistic missile attacks. It was launched in 2000 after the Kargil War by the Atal Bihari Vajpayee government. Testing was carried out and continuing as of 2006, and the system was expected to be operational within four years according to the head of the country's missiles development programme, Vijay Kumar Saraswat.
The RIM-161 Standard Missile 3 (SM-3) is a ship-based surface-to-air missile used by the United States Navy to intercept short- and intermediate-range ballistic missiles as a part of Aegis Ballistic Missile Defense System. Although primarily designed as an anti-ballistic missile, the SM-3 has also been employed in an anti-satellite capacity against a satellite at the lower end of low Earth orbit. The SM-3 is primarily used and tested by the United States Navy and also operated by the Japan Maritime Self-Defense Force.
A kinetic energy weapon is a projectile weapon based solely on a projectile's kinetic energy to inflict damage to a target, instead of using any explosive, incendiary/thermal, chemical or radiological payload. All kinetic weapons work by attaining a high flight speed — generally supersonic or even up to hypervelocity — and collide with their targets, converting its kinetic energy and relative impulse into destructive shock waves, heat and cavitation. In kinetic weapons with unpowered flight, the muzzle velocity or launch velocity often determines the effective range and potential damage of the kinetic projectile.
The RIM-113 Shipboard Intermediate Range Combat System, or SIRCS, was an advanced surface-to-air missile proposed by the United States Navy in the 1970s. The project failed to be approved for funding and was cancelled in 1979.
Missile defense systems are a type of missile defense intended to shield a country against incoming missiles, such as intercontinental ballistic missiles (ICBMs) or other ballistic missiles. The United States, Russia, India, France, Israel, Italy, United Kingdom, China and Iran have all developed missile defense systems.
The Arrow 3 or Hetz 3 is an exoatmospheric hypersonic anti-ballistic missile, jointly funded, developed and produced by Israel and the United States. Undertaken by Israel Aerospace Industries (IAI) and Boeing, it is overseen by the Israeli Ministry of Defense's "Homa" administration and the U.S. Missile Defense Agency. It provides exo-atmospheric interception of ballistic missiles, including intercontinental ballistic missiles (ICBMs) carrying nuclear, chemical, biological or conventional warheads. With divert motor capability, its kill vehicle can switch directions dramatically, allowing it to pivot to see approaching satellites. The missile's reported flight range is up to 2,400 km (1,500 mi).
The Ground-Based Interceptor (GBI) is the anti-ballistic missile component of the United States' Ground-Based Midcourse Defense (GMD) system.
The Exoatmospheric Reentry-vehicle Interceptor Subsystem, or ERIS, program, was a component of the United States' Strategic Defense Initiative during the Cold War. The ERIS system was named after Eris, Greek goddess of strife. ERIS was a kinetic kill system, launched from a ground-based system, and impacting directly to destroy an incoming Intercontinental ballistic missile (ICBM) before the targeted ICBM re-entered the Earth's atmosphere.
