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 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).
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than 5,500 kilometres (3,400 mi), primarily designed for nuclear weapons delivery. Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicle (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. The United States, Russia, China, France, India, the United Kingdom, Israel, and North Korea are the only countries known to have operational ICBMs.
National missile defense (NMD) refers to the nationwide antimissile program the United States has had in 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.
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.
Sary Shagan is an anti-ballistic missile testing range located in Kazakhstan.
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.
Terra-3 was a Soviet laser testing centre, located on the Sary Shagan anti-ballistic missile (ABM) testing range in the Karaganda Region of Kazakhstan. It was originally built to test missile defence concepts, but these attempts were dropped after the Anti-Ballistic Missile Treaty was signed. The site later hosted two modest devices used primarily for experiments in space tracking. Several other laser test sites were also active during this period. During the 1980s, officials within the United States Department of Defense (DoD) suggested it was the site of a prototypical anti-satellite weapon system. The site was abandoned and is now partially disassembled.
The S-300VM "Antey-2500" is a Russian anti-ballistic missile system. The system is designed to target short- and medium-range ballistic missiles, aeroballistic missiles, cruise missiles, fixed-wing aircraft, loitering ECM platforms, and precision-guided munitions.
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.
The A-35 anti-ballistic missile system was a Soviet military anti-ballistic missile (ABM) system deployed around Moscow to intercept enemy ballistic missiles targeting the city or its surrounding areas. The A-35 was the only Soviet ABM system allowed under the 1972 Anti-Ballistic Missile Treaty. In development as of the 1960s and in operation from June 1972 until the 1990s, it featured the nuclear-armed A350 exoatmospheric interceptor missile. The A-35 was supported by two Dunay radars and the Soviet early warning system. It was followed by the A-135 in the early 1990s.
Dunay radar was a system of two Soviet radars used to detect American ballistic missiles fired at Moscow. They were part of the A-35 anti-ballistic missile system. One sector of one of the radars, the Dunay-3U is still operational and is run by the Russian Space Forces as part of the Main Control Centre of Outer Space.
Gabala Radar Station was a Daryal-type bistatic Passive electronically scanned array early warning radar, built by the Soviet Union in the Qabala district of the Azerbaijan SSR in 1985. It was operated by the Russian Aerospace Defence Forces and closed at the end of 2012. The radar station had a range of up to 6,000 kilometres (3,728 mi), and was designed to detect missile launches as far as the Indian Ocean. The radar's surveillance covered Iran, Turkey, India, Iraq and the entire Middle East. It could detect the launch of missiles and track the whole trajectory to enable a ballistic missile defense system to intercept an offensive strike. The Radar Station hosted about 1,000 Russian servicemen with about 500 Azerbaijanis.
Baranavichy Radar Station is a 70M6 Volga-type radar near Hantsavichy. It is an early warning radar, which is run by the Russian Space Forces. It is designed to identify launches of ballistic missiles from western Europe and can also track some artificial satellites, partly replacing the demolished radar station at Skrunda in Latvia.
The 53T6 is a Russian anti-ballistic missile. Designed in 1978 and in service since 1995, it is a component of the A-135 anti-ballistic missile system.
The Daryal-type radar is a Soviet bistatic early-warning radar. It consists of two separate large active phased-array antennas separated by around 500 metres (1,640 ft) to 1.5 kilometres (4,921 ft). The transmitter array is 30 m × 40 m and the receiver is 80 m × 80 m in size. The system is a VHF system operating at a wavelength of 1.5 to 2 meters. Its initial transmit capacity was 50 MW with a target capacity of 350 MW.
Dnestr radar and Dnepr radar, both known by the NATO reporting name Hen House are the first generation of Soviet space surveillance and early warning radars. Six radars of this type were built around the periphery of the Soviet Union starting in the 1960s to provide ballistic missile warnings for attacks from different directions. They were the primary Soviet early warning radars for much of the later Cold War. In common with other Soviet and Russian early warning radars they are named after rivers, the Dnestr and the Dnepr.
The Don-2N radar is a large missile defense and early warning active electronically scanned array radar outside Moscow, and a key part of the Russian A-135 anti-ballistic missile system designed for the defense of the capital against ballistic missiles. Located near Sofrino in Pushkinsky District of Moscow Oblast, it is a quadrangular frustum 33 m (108 ft) tall with sides 130 m (427 ft) long at the bottom, and 90 m (295 ft) long at the top. Each of its four faces has an 18 m (59 ft) diameter Super high frequency band radar giving 360 degree coverage. To the right of each circular search and track array, separated by a vertical structure for shielding, is a square antenna array for guiding the interceptor missile by data link. The system is run by an Elbrus-2 supercomputer.
Balkhash Radar Station is the site of two generations of Soviet and Russian early warning radars. It is located on the west coast of Lake Balkhash near Sary Shagan test site in Kazakhstan. Although it was used for monitoring satellites in low Earth orbit it was mainly a key part of the Russian system of warning against missile attack. It provided coverage of western and central China, India, Pakistan and submarine missile launches in the Bay of Bengal. There have been six radars at this site, the last one was removed from service on 1 June 2020, and it was run by the Russian Space Forces.
Olenegorsk Radar Station is the site of a Soviet and Russian early warning radar. It is located near Olenegorsk on the Kola Peninsula, north of the Arctic Circle in north west Russia. It is considered to be a key part of the Russian early warning system against ballistic missile attack, and provides coverage of ballistic missile launches in the Norwegian Sea and North Sea. The station is operated by the Russian Space Forces.
The 5N65 radar was a Soviet military phased array radar initially designed for the S-225 anti-ballistic missile system which was never commissioned. The radar was later installed near the Kura Test Range in Kamchatka in the Russian Far East as a part of 5K17 tracking and measuring system and was demolished in 2006.
