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 Strategic Defense Initiative (SDI), derisively nicknamed the Star Wars program, was a proposed missile defense system intended to protect the United States from attack by ballistic nuclear missiles. The program was announced in 1983, by President Ronald Reagan. Reagan called for a system that would render nuclear weapons obsolete, and to end the doctrine of mutual assured destruction (MAD), which he described as a "suicide pact". Elements of the program reemerged in 2019 under the Space Development Agency (SDA).
The MIM-104 Patriot is a mobile interceptor missile surface-to-air missile (SAM) system, the primary such system used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system. The AN/MPQ-53 at the heart of the system is known as the "Phased Array Tracking Radar to Intercept on Target," which is a backronym for "Patriot". In 1984, the Patriot system began to replace the Nike Hercules system as the U.S. Army's primary high to medium air defense (HIMAD) system and the MIM-23 Hawk system as the U.S. Army's medium tactical air defense system. In addition to these roles, Patriot has been given a function in the U.S. Army's anti-ballistic missile (ABM) system. As of 2016, the system is expected to stay fielded until at least 2040.
The Arrow or Hetz is a family of anti-ballistic missiles designed to fulfill an Israeli requirement for a missile defense system that would be more effective against ballistic missiles than the MIM-104 Patriot surface-to-air missile. Jointly funded and produced by Israel and the United States, development of the system began in 1986 and has continued since, drawing some contested criticism. Undertaken by the MALAM division of the 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 forms the long-range layer of Israel's multi-tiered missile defence system, along with David's Sling and Iron Dome and Iron Beam [experimental].
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 Dongfeng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng is a two-stage, solid-fuel, single-warhead medium-range ballistic missile developed by China's Changfeng Mechanics and Electronics Technology Academy. A part of the Dongfeng missile family, the DF-21's development started in the late 1960s, and it was completed around 1985–86, but not deployed until 1991. It was developed from the JL-1 submarine-launched missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers; approximately 10-11 missiles can be built annually.
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.
The RIM-174 Standard Extended Range Active Missile (ERAM), or Standard Missile 6 (SM-6), is a missile in current production for the United States Navy (USN). It was designed for extended-range anti-air warfare (ER-AAW) purposes, providing capability against fixed and rotary-wing aircraft, unmanned aerial vehicles, anti-ship cruise missiles in flight, both over sea and land, and terminal ballistic missile defense. It can also be used as a high-speed anti-ship missile. The missile uses the airframe of the earlier SM-2ER Block IV (RIM-156A) missile, adding the active radar homing seeker from the AIM-120C AMRAAM in place of the semi‑active seeker of the previous design. This will improve the capability of the Standard missile against highly agile targets and targets beyond the effective range of the launching vessels' target illumination radars. Initial operating capability was planned for 2013 and was achieved on 27 November 2013. The SM-6 is not meant to replace the SM-2 series of missiles but will serve alongside and provide extended range and increased firepower. It was approved for export in January 2017. An air-to-air variant of the SM-6, known as the AIM-174, is the first dedicated long-range air-to-air missile employed by the USN since the 2004 retirement of the AIM-54 Phoenix. SM-6 can also be fired from the U.S. Army's Typhon missile launcher as part of the Strategic Mid-range Fires System (SMRF).
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 their 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 Lightweight Exo-atmospheric Projectile (LEAP) is a lightweight miniaturized kinetic kill vehicle designed to destroy incoming ballistic missiles both inside or outside the Earth's atmosphere. The warhead is delivered to the interception point by a system such as the Aegis Ballistic Missile Defense System.
Quick Kill is an active protection system (APS) designed to destroy incoming anti-tank missiles, rockets, and grenades. The Quick Kill system is designed and produced by Raytheon for the U.S. Army. The Quick Kill system was part of the United States Army's Future Combat Systems.
The Ground-Based Interceptor (GBI) is the anti-ballistic missile component of the United States' Ground-Based Midcourse Defense (GMD) system.
The AN/TPY-2 Surveillance Transportable Radar, also called the Forward Based X-Band Transportable (FBX-T) is a long-range, very high-altitude active digital antenna array X band surveillance radar designed to add a tier to existing missile and air defence systems. It has a range of 2,900 mi. Made by Raytheon, it is the primary radar for the Terminal High Altitude Area Defense (THAAD) missile system, but also cues the AN/MPQ-53 radar of the MIM-104 Patriot system. Patriot PAC-3 is a lower-altitude missile and air defense system than THAAD.
The Miniature Self-Defense Missile (MSDM) is a US Air Force concept for a weapon designed to take out anti-aircraft missiles. Lacking a warhead, it requires a direct impact to destroy its target. It was first announced in 2015 and is being developed by Raytheon with first fly test expected by 2023.
