87-605: The Network Centric Airborne Defense Element (NCADE) is an anti-ballistic missile system being developed by Raytheon for the Missile Defense Agency . On Sept. 18, 2008 Raytheon announced it had been awarded a $ 10 million contract to continue NCADE research and development. The NCADE system is a boost phase interceptor based heavily on the AIM-120 AMRAAM , with the AMRAAM fragmentation warhead replaced by

174-692: A Taepodong-1 missile over northern Japan, the Japanese have been jointly developing a new surface-to-air interceptor known as the Patriot Advanced Capability 3 (PAC-3) with the US. Tests have been successful, and there are 11 locations that are planned for the PAC-3 to be installed. The approximate locations are near major air bases, like Kadena Air Base , and ammunition storage centers of the Japanese military. The exact location are not known to

261-408: 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). There are a limited number of systems worldwide that can intercept intercontinental ballistic missiles : During 1993,

348-558: A hit-to-kill vehicle powered by a hydroxylammonium nitrate monopropellant rocket motor from Aerojet . The launch vehicle will be a Boeing F-15C Golden Eagle with an AESA radar . This article relating to missiles is a stub . You can help Misplaced Pages by expanding it . 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

435-467: A land-based anti-ballistic missile test on 11 January 2010. The test was exoatmospheric and done in midcourse phase and with a kinetic kill vehicle . China is the second country after US that demonstrated intercepting ballistic missile with a kinetic kill vehicle, the interceptor missile was a SC-19 . The sources suggest the system is not operationally deployed as of 2010. On 27 January 2013, China did another anti ballistic missile test. According to

522-635: A Spitfire happened upon a V-2 rising through the trees, and fired on it with no effect. This led to allied efforts to capture launching sites in Belgium and the Netherlands. A wartime study by Bell Labs into the task of shooting down ballistic missiles in flight concluded it was not possible. In order to intercept a missile, one needs to be able to steer the attack onto the missile before it hits. A V-2's speed would require guns of effectively instantaneous reaction time, or some sort of weapon with ranges on

609-519: A complex test designed to validate how the system can detect, identify, track and then discriminate real from decoy targets delivered into space by an improved Silver Sparrow target missile. According to officials, the milestone test paves the way toward low-rate initial production of the Arrow 3. David's Sling (Hebrew: קלע דוד), also sometimes called Magic Wand (Hebrew: שרביט קסמים), is an Israel Defense Forces military system being jointly developed by

696-506: A decade when Safeguard was announced, and the arguments against such a system were well known both in the military and civilian circles. In military circles, the most basic argument against Safeguard was that adding an ABM requires the Soviets to build another ICBM to counter it, but the same is true if the US builds another ICBM instead. The Air Force was far more interested in building more of their own ICBMs than Army ABMs, and lobbied against

783-574: A few more times, including in November 2015. The HQ-29, a counterpart to the MIM-104F PAC-3 , was first tested in 2011. Surface-to-air missiles that supposedly have some terminal ABM capability (as opposed to midcourse capability): The technology and experience from the successful anti-satellite test using a ground-launched interceptor during January 2007 was immediately applied to current ABM efforts and development. China carried out

870-407: A head at a meeting outside Boston, when an estimated 1,000 to 2,000 people showed up to express their displeasure in spite of a raging blizzard. Congressmen were flooded by letters from constituents demanding the sites be moved, and Congress was soon threatening to freeze all additional funds for the system. Nixon announced construction would be delayed while the system underwent a review. The review

957-820: A latest generation ABM system with a radar site in the Czech Republic and the launch site in Poland . The system was announced to be aimed against ICBMs from Iran and North Korea. This caused harsh comments by Russian President Vladimir Putin at the Organization for Security and Co-operation in Europe (OSCE) security conference during spring 2007 in Munich. Other European ministers commented that any change of strategic weapons should be negotiated on NATO level and not 'unilaterally' [sic, actually bilaterally] between

1044-671: A letter of intent and agreeing to initial joint requirements. The ultimate goal of the project is to develop a countermeasure that could be integrated into the French-led EU TWISTER (Timely Warning and Interception with Space-based TheatER surveillance) capability program. TWISTER, launched in 2019 with MBDA France acting as lead contractor as well, is intended to be an air defense system capable of early warning, tracking and intercepting high-performance air threats, including defense against ballistic missiles (BMD) and hypersonic vehicles. The program involves France, Italy, Spain ,

1131-706: A new missile defence system in Central Europe. According to a July 2007 survey, a majority of Poles were opposed to hosting a component of the system in Poland. By 28 July 2016 Missile Defense Agency planning and agreements had clarified enough to give more details about the Aegis Ashore sites in Romania (2014) and Poland (2018). Project 640 had been the PRC's indigenous effort to develop ABM capability. The Academy of Anti-Ballistic Missile & Anti-Satellite

1218-473: A series of talks, the Johnson administration was under intense pressure to deploy an ABM system. In 1966 Congress voted to provide deployment funding for Nike-X, although McNamara refused to use it. As the 1967 elections approached, it became clear that this was going to be a major election issue. McNamara proposed arms limitations talks with the Soviets to put upper limits on the numbers of ABMs and warheads, but

1305-643: A subject of debate among historians and political commentators. Through the Safeguard era, talks between the US and Soviet Union originally started by President Lyndon B. Johnson were continuing. The Anti-Ballistic Missile Treaty of 1972 limited the US and Soviet Union to two ABM sites each. Safeguard was scaled back to sites in North Dakota and Montana , abandoning initial work at a site in Missouri, and cancelling all other planned bases. Construction on

1392-474: A symposium was held by western European nations to discuss potential future ballistic missile defence programs. In the end, the council recommended deployment of early warning and surveillance systems as well as regionally controlled defence systems. During spring 2006 reports about negotiations between the United States, Poland, and the Czech Republic were published. The plans propose the installation of

1479-409: A target going faster than ICBM warheads. On 16 November 2020 an SM-3 Block IIA interceptor successfully destroyed an ICBM in mid-course, under Link-16 Command and Control, Battle Management, and Communications ( C2BMC ). The U.S. Army Terminal High Altitude Area Defense (THAAD) system began production in 2008. Its stated range as a short to intermediate ballistic missile interceptor means that it

1566-430: Is South Korea's next anti-ballistic missile generation. It is expected to have a range of 150 km and be able to intercept targets between 40 km and 100 km of altitude, and it can also be used as an aircraft interceptor. The L-SAM system is expected to be complete and ready to use in 2024. The idea of destroying rockets before they can hit their target dates from the first use of modern missiles in warfare,

1653-582: Is expected to perform much better than the Patriot did in the Gulf War. On 29 July 2004 Israel and the United States carried out a joint experiment in the US, in which the Arrow was launched against a real Scud missile. The experiment was a success, as the Arrow destroyed the Scud with a direct hit. During December 2005 the system was deployed successfully in a test against a replicated Shahab-3 missile. This feat

1740-629: Is for terminal phase interception. The current Phase-1 of the Indian ABM system can intercept ballistic missiles of range up to 2,000 km and the Phase-2 will increase it up to 5,000 km. Iran used Arman and S-300 missile systems for ballistic missile defense. The Arrow project was begun after the U.S. and Israel agreed to co-fund it on 6 May 1986. The Arrow ABM system was designed and constructed in Israel with financial support by

1827-852: Is not designed to hit midcourse ICBMs, which can reach terminal phase speeds of mach 8 or greater. The THAAD interceptor has a reported maximum speed of mach 8, and THAAD has repeatedly proven it can intercept descending exoatmospheric missiles in a ballistic trajectory. The U.S. Army Ground-Based Midcourse Defense (GMD) system was developed by the Missile Defense Agency . It combines ground-based AN/FPS-132 Upgraded Early Warning Radar installations and mobile AN/TPY-2 X-band radars with 44 exoatmospheric interceptors stationed in underground silos around California and Alaska, to protect against low-count ICBM attacks from rogue states. Each Ground-Based Interceptor (GBI) rocket carries an Exoatmospheric Kill Vehicle (EKV) kinetic kill interceptor, with 97% probability of intercept when four interceptors are launched at

1914-658: Is the Sky Bow III (TK-3) . Since North Korea started developing its nuclear weapon program, South Korea has been under imminent danger. South Korea started its BDM program by acquiring 8 batteries of the MIM-104 Patriot ( PAC-2 ) missiles from the United States. The PAC-2 was developed to destroy incoming aircraft and is now unreliable in defending a ballistic missile attack from North Korea, as they have developed further their nuclear program. As of 2018, South Korea decided to improve its defense system by upgrading to

2001-502: Is to propose an architecture and technology maturation concept study for an endo-atmospheric interceptor to counter new, highly sophisticated emerging threats. HYDIS² is centered around the MBDA's Aquila hypersonic missile interceptor concept and will involve a consortium of 19 partners and over 30 subcontractors from 14 European countries. France, Germany, Italy and the Netherlands have already confirmed their support and commitment, by signing

2088-554: The Aegis Ballistic Missile Defense System . Japan is currently modifying another 4 destroyers so that they can take part of their defense force against ballistic missiles, bringing the total number to 8 ships. The Moscow ABM defense system was designed with the aim of being able to intercept the ICBM warheads aimed at Moscow and other important industrial regions, and is based on: In several tests,

2175-620: The Defence Research and Development Organisation (DRDO) is developing a new Prithvi interceptor missile code-named PDV. The PDV is designed to take out the target missile at altitudes above 150 km (93 mi). The first PDV was successfully test fired on 27 April 2014. According to scientist V K Saraswat of the DRDO, the missiles will work in tandem to ensure a hit probability of 99.8 percent. On 15 May 2016, India successfully launched AAD renamed Ashwin from Abdul Kalam Island off

2262-551: The Fakel 5V61 (known in the west as Galosh), was developed to carry the larger warhead and carry it much further from the launch site. Further development continued, and the A-35 anti-ballistic missile system , designed to protect Moscow, became operational in 1971. A-35 was designed for exoatmospheric interceptions, and would have been highly susceptible to a well-arranged attack using multiple warheads and radar black-out techniques. A-35

2349-587: The Glassboro Summit Conference ultimately came to nothing. By late 1967 it was clear the Soviets were not seriously considering limitations, and were continuing deployment of their own ABM system. In September, the Chinese tested their first H-bomb . McNamara and Johnson seized on this as a solution to the problem; a defense against the tiny Chinese fleet was both technically possible and relatively low-cost. Deploying this system would mute

2436-586: The Kapustin Yar , and intercepted by a V-1000 launched from Sary-Shagan . The dummy warhead was destroyed by the impact of 16,000 tungsten-carbide spherical impactors 140 seconds after launch, at an altitude of 25 km (82,000 ft). The V-1000 missile system was nonetheless considered not reliable enough and abandoned in favour of nuclear-armed ABMs. Retired V-1000 was used to develop 1Ya2TA sounding rocket , capable of launching 520 kg scientific payload to an altitude of 400 km. A much larger missile,

2523-717: The PAC-3 , which has a hit-to-kill capability against incoming missiles. The main reason that the South Korean anti-ballistic defense system is not very developed is because they have tried to developed their own, without help from other countries, since the beginning of the 1990s. The South Korean Defense Acquisition Program Administration (DAPA) has confirmed that it has test launched the L-SAM system in February 2022. This particular missile has been in development since 2019 and

2610-532: The US Air Force and nuclear weapons establishments who suggested it would be much simpler to build more nuclear warheads and guarantee mutually assured destruction . Zeus was eventually cancelled in 1963. In 1958, the U.S. sought to explore whether airbursting nuclear weapons might be used to ward off ICBMs. It conducted several test explosions of low-yield nuclear weapons – 1.7kt boosted fission W25 warheads – launched from ships to very high altitudes over

2697-582: The ABM, inherited the system with his election win . He also inherited a massive NIMBY backlash that blew up in late 1968 when the Army chose to deploy the missiles in suburban locations to allow future expansion to be easier. City-dwellers could tolerate the idea of an armed rocket attack against bombers going on over their heads. They were less comfortable with the concept of nuclear anti-missiles detonating against incoming missiles at low altitudes. The issue came to

2784-430: The Army continually. In the public sphere, opinion by the late 1960s was anti-military in general, and in an era of ongoing Strategic Arms Limitation Talks the entire concept was derided as sabre rattling. Safeguard had been developed to calm opposition but found itself just as heavily opposed. Nixon pressed ahead in spite of objections and complaints about limited performance, and the reasons for his strong support remains

2871-721: The Aster 30 Block II, which can destroy ballistic missiles up to a maximum range of 3,000 km (1,900 mi). It will incorporate a kill vehicle warhead. Involving France, Italy, Germany and the Netherlands , the HYDIS² (HYpersonic Defence Interceptor Study) was announced on June 20, 2023 and is a project led by MBDA . It was selected in March 2023 and is partially funded by the European Defense Fund (EDF). Its aim

2958-573: The Aster 30 missile and on 1 December 2011 a successful interception of a Black Sparrow ballistic target missile. The Horizon-class frigates in French and Italian service, the Royal Navy 's Type 45 destroyers , and the French and Italian FREMM-class frigates are all armed with PAAMS (or variants of it) integrating Aster 15 and Aster 30 missiles. France and Italy are developing a new variant,

3045-607: The Chinese Defence Ministry, the missile launch is defensive in character and is not aimed against any countries. Experts hailed China's technological breakthrough because it is difficult to intercept ballistic missiles that have reached the highest point and speed in the middle of their course. Only two countries, including the US, have successfully conducted such a test in the past decade. On 4 February 2021, China successfully conducted mid-course intercept anti-ballistic missile test. Military analysts indicates that

3132-539: The German V-1 and V-2 program of World War II . British fighters destroyed some V-1 "buzz bombs" in flight, although concentrated barrages of heavy anti-aircraft artillery had greater success. Under the lend-lease program, 200 US 90 mm AA guns with SCR-584 radars and Western Electric / Bell Labs computers were sent to the UK. These demonstrated a 95% success rate against V-1s that flew into their range. The V-2,

3219-594: The Israeli defense contractor Rafael Advanced Defense Systems and the American defense contractor Raytheon , designed to intercept tactical ballistic missiles, as well as medium- to long-range rockets and slower-flying cruise missiles, such as those possessed by Hezbollah , fired at ranges from 40 km to 300 km. It is designed with the aim of intercepting the newest generation of tactical ballistic missiles, such as Iskander . Since 1998, when North Korea launched

3306-724: The Missile Site Radar, the Spartan missile launchers, co-located Sprint missile launchers, and Remote Sprint missile launchers. The PAR was a large passive electronically scanned array radar that was intended to detect incoming ballistic missile warheads as they crossed over the North Pole region. Potential targets detected by the PAR would be sent to the Missile Site Radar (MSR) and to North American Aerospace Defense Command . Two radar sites were intended to be constructed on

3393-562: The Montana MSR site 48°08′18″N 111°45′41″W  /  48.13831°N 111.76152°W  / 48.13831; -111.76152 were dismantled and buried. Remote Sprint Launchers were established around the MSR main complex in order to place missile launchers closer to their intended targets, and thus reduce the flight range to the targets. Four sites were completed, and they still remain there, 10 to 20 miles (16 to 32 km) around

3480-556: The Netherlands, Finland and Germany. Competing against HYDIS², the EU HYDEF (European Hypersonic Defence Interceptor) also covers the concept phase to develop an endo-atmospheric interceptor and is related to TWISTER. Selected in July 2022, it is also partially funded by the EDF. It is coordinated by Spain's SENER Aeroespacial Sociedad Anonima , while Germany's Diehl Defence is serving as

3567-614: The U.S. Patriot missiles. China has acquired and is license-producing the S-300PMU-2/S-300PMU-1 series of terminal ABM-capable SAMs. China-produced HQ-9 SAM system may possess terminal ABM capabilities. PRC Navy's operating modern air-defense destroyers known as the Type 052C Destroyer and Type 051C Destroyer are armed with naval HQ-9 missiles. The HQ-19, similar to the THAAD , was first tested in 2003, and subsequently

3654-482: The U.S. and other states (although most strategic arms reduction treaties were between the Soviet Union and U.S., not NATO). The German foreign minister Frank-Walter Steinmeier , a Social Democrat, expressed severe concerns about the way in which the U.S. had conveyed its plans to its European partners and criticised the U.S. administration for not having consulted Russia prior to announcing its endeavours to deploy

3741-490: The U.S. military have demonstrated the feasibility of destroying long and short range ballistic missiles. Combat effectiveness of newer systems against 1950s tactical ballistic missiles seems very high, as the MIM-104 Patriot (PAC-1 and PAC-2) had a 100% success rate in Operation Iraqi Freedom. The U.S. Navy Aegis Ballistic Missile Defense System (Aegis BMD) uses RIM-161 Standard Missile 3 , which hit

3828-567: The US's W47 of the UGM-27 Polaris weighed only 330 kilograms (730 lb). This meant that much smaller rockets could carry these new warheads to the same range, greatly reducing the cost of the missile, making them far cheaper than bombers or any other delivery system. When Nikita Khrushchev angrily boasted that the Soviet Union was producing new missiles "like sausages", the US responded by building more ICBMs of their own, rather than attempting to defend against them with Zeus. Adding to

3915-404: The United States by a multibillion-dollar development program called "Minhelet Homa" (Wall Administration) with the participation of companies like Israel Military Industries , Tadiran and Israel Aerospace Industries . During 1998 the Israeli military conducted a successful test of their Arrow missile. Designed to intercept incoming missiles travelling at up to 2-mile/s (3 km/s), the Arrow

4002-620: The Whiteman AFB location was canceled despite the fact that specific missile and radar site locations had already been selected. Construction was actually commenced at the North Dakota and Montana sites, but only the North Dakota site was completed. Remnants of the incomplete PAR system still remain in rural Montana. The Safeguard system consisted of several primary components, the Perimeter Acquisition Radar,

4089-473: The Zeus base. However, in an era when ICBMs cost about the same as a strategic bomber , such an attack would cost an enormous amount. Through the late 1950s a new generation of much lighter thermonuclear bombs cut warhead weight from 3,000 kilograms (6,600 lb) in the case of the original Soviet R-7 Semyorka ICBM to perhaps 1,000 kilograms (2,200 lb), and further reductions were known to be possible -

4176-546: The aim of creating a missile capable of intercepting the V-2. But defences against Soviet long-range bombers took priority until 1957, when the Soviet Union demonstrated its advances in ICBM technology with the launch of Sputnik , the Earth's first artificial satellite. The US Army accelerated development of their LIM-49 Nike Zeus system in response. Zeus was criticized throughout its development program, especially from those within

4263-623: The atmosphere) interceptor system, intercepted a Prithvi-II ballistic missile. The PAD missile has the secondary stage of the Prithvi missile and can reach altitude of 80 km (50 mi). During the test, the target missile was intercepted at a 50 km (31 mi) altitude. On 6 December 2007, the Advanced Air Defence (AAD) missile system was tested successfully. This missile is an endo-atmospheric interceptor with an altitude of 30 km (19 mi). First reported in 2009,

4350-502: The case, but Argus returned key data about a related effect, the nuclear electromagnetic pulse (NEMP). Other countries were also involved in early ABM research. A more advanced project was at CARDE in Canada, which researched the main problems of ABM systems. A key problem with any radar system is that the signal is in the form of a cone, which spreads with distance from the transmitter. For long-distance interceptions like ABM systems,

4437-575: The coast of Odisha . As of 8 January 2020, the BMD programme has been completed and the Indian Air Force and the DRDO are awaiting government's final approval before the system is deployed to protect New Delhi and then Mumbai. After these two cities, it will be deployed in other major cities and regions. India has structured a five-layer missile shield for Delhi as of 9 June 2019: PAD and PDV are designed for mid-course interception, while AAD

4524-431: The cost; When you are looking toward city defense, it needs to be a perfect or near perfect system because, as I examined the possibility of even a thick defense of cities, I have found that even the most optimistic projections, considering the highest development of the art, would mean that we would still lose 30 million to 40 million lives... However, they disagreed with the concept of a light city defense as well. There

4611-427: The first true ballistic missile, has no known record of being destroyed in the air. SCR-584's could be used to plot the trajectories of the missiles and provide some warning, but were more useful in backtracking their ballistic trajectory and determining the rough launch locations. The Allies launched Operation Crossbow to find and destroy V-2s before launch, but these operations were largely ineffective. In one instance

4698-458: The go-ahead to begin deployment of such a system on 17 August 1956. Their test system, known simply as System A, was based on the V-1000 missile, which was similar to the early US efforts. The first successful test interception was carried out on 24 November 1960, and the first with a live warhead on 4 March 1961. In this test, a dummy warhead was released by a R-12 ballistic missile launched from

4785-517: The incoming warhead with radiation rather than heat or blast. The Spartan carried a weapon with a 5 megatons of TNT (21 PJ) yield; the Sprint in the 1 kiloton of TNT (4.2 TJ) range. The envisioned sequence was as follows: Plans were made in the late 1960s to deploy Safeguard systems in three locations, Whiteman AFB , Missouri, Malmstrom AFB , Montana, and Grand Forks AFB , North Dakota, to protect important strategic weapons assets. However

4872-418: The inherent inaccuracy of the radar makes an interception difficult. CARDE considered using a terminal guidance system to address the accuracy concerns, and developed several advanced infrared detectors for this role. They also studied a number of missile airframe designs, a new and much more powerful solid rocket fuel, and numerous systems for testing it all. After a series of drastic budget reductions during

4959-409: The interceptor missile to climb to its altitude. Zeus had limited traffic handling capabilities, designed to deal with a small number of attacking missiles arriving over a period of as long as an hour. It was calculated that an attack of only four missiles arriving within one minute would allow one of the warheads to pass by while the system was busy attacking others, making it relatively easy to attack

5046-471: The late 1950s the research ended. One offshoot of the project was Gerald Bull 's system for inexpensive high-speed testing, consisting of missile airframes shot from a sabot round, which would later be the basis of Project HARP . Another was the CRV7 and Black Brant rockets, which used the new solid rocket fuel. The Soviet military had requested funding for ABM research as early as 1953, but were only given

5133-412: The missile bases themselves, ensuring that no limited attack could be contemplated. This did not have to be perfect, or even close to it; When you are talking about protecting your deterrent, it need not be perfect. It is necessary only to protect enough of the deterrent that the retaliatory second strike will be of such magnitude that the enemy would think twice about launching a first strike. Safeguard

5220-560: The missile before it was below 20,000 feet (6.1 km) altitude, combined with the 5 miles (8.0 km) per second terminal speed of the RV meant there were only 2 to 3 seconds to develop a track and shoot the interceptor. This would demand extremely fast missiles, high-performance radars and advanced computers. In 1963, Robert McNamara cancelled the upcoming deployment of Zeus and announced that money would instead be provided for research into this new system, now known as Nike-X. Construction on

5307-556: The new phased array radar and its associated computer systems began at the MAR-I site in White Sands Missile Range . MAR could track hundreds of warheads and the interceptor missiles sent to attack them, meaning the Soviets would have to launch hundreds of missiles if they wanted to overwhelm it. And now that decoys were no longer an issue, the cost-exchange ratio fell back to reasonable levels. The Nike-X developed

5394-401: The newly created ARPA to suggest solutions. ARPA noted that because the decoys were lighter than the actual warhead, they would slow down more rapidly as they reentered the lower atmosphere. They proposed a system using a short range missile that could wait until the warhead was below 100,000 feet (30 km) altitude, at which point the decoys would have been decluttered . Desiring to destroy

5481-879: The northern border of the United States, one in Montana and one in North Dakota. Construction was begun at both locations, but because of the ratification of the Anti-Ballistic Missile Treaty , only the site at North Dakota was completed. That site, near Cavalier, North Dakota , is now operated by the United States Space Force as Cavalier Space Force Station . Remnants of the Montana PAR site are located east of Conrad, Montana , at 48°17′15.83″N 111°20′32.39″W  /  48.2877306°N 111.3423306°W  / 48.2877306; -111.3423306 . The Missile Site Radar

5568-420: The ongoing debate, even over the long term if the option was open to expand the system to Nike-X coverage levels in the future. On 18 September 1967, McNamara announced the Sentinel program, with 17 bases covering all of the US, along with a total of just under 700 missiles, about 1 ⁄ 10 the number in a baseline Nike-X. Nixon, having campaigned that the Democrats were deliberately dragging their feet on

5655-449: The order of dozens of miles, neither of which appeared possible. This was, however, just before the emergence of high-speed computing systems. By the mid-1950s, things had changed considerably, and many forces worldwide were considering ABM systems. The American armed forces began experimenting with anti-missile missiles soon after World War II, as the extent of German research into rocketry became clear. Project Wizard began in 1946, with

5742-437: The overall technical lead. They are heading a consortium of partners and subcontractors from various EU countries. India has an active ABM development effort using indigenously developed and integrated radars, and indigenous missiles. In November 2006, India successfully conducted the PADE (Prithvi Air Defence Exercise) in which an anti-ballistic missile, called the Prithvi Air Defence (PAD) , an exo-atmospheric (outside

5829-408: The problems, as the warhead weight dropped, existing missiles had leftover throw weight that could be used for various radar decoys , which Zeus proved unable to distinguish from the actual RV. The Army calculated that as many as twenty Zeus' would have to be fired to ensure a single incoming missile was destroyed. Faced with these problems, both the Eisenhower and Kennedy administrations turned to

5916-434: The public. A military spokesman said that tests had been done on two sites, one of them a business park in central Tokyo, and Ichigaya – a site not far from the Imperial Palace. Along with the PAC-3, Japan has installed a US-developed ship-based anti-ballistic missile system, which was tested successfully on 18 December 2007. Japan has 4 destroyers of this type capable of carrying RIM-161 Standard Missile 3 and equipped with

6003-497: The same calculations were run for Nike-X, it was calculated that they would have to deploy 7,000 Sprint missiles , and the cost-exchange ratio was 20-to-1 in favor of the Soviets. When presented with these numbers, McNamara concluded that deploying Nike-X would prompt to Soviets to build more ICBMs, increasing the risk of an accidental war. From this point on, he opposed building a "heavy" ABM system like Nike-X. In spite of all of these problems, which McNamara repeatedly made public in

6090-583: The same sort of trouble as the Zeus before it. In this case it was ironically due to the Soviet's own ABM system which was very similar to Zeus. To ensure they could defeat it, the US Air Force began equipping their own ICBMs with decoys, which would defeat the Soviet's Zeus-like system. However, concerned that the Soviets would upgrade their system to Nike-X like performance, they instead began replacing their warheads with lighter ones, and carrying three of them. This meant that every US missile would require three (or six accounting for redundancy) interceptors. When

6177-402: The southern Atlantic Ocean. Such an explosion releases a burst of X-rays in the Earth's atmosphere, causing secondary showers of charged particles over an area hundreds of miles across. These can become trapped in the Earth' magnetic field, creating an artificial radiation belt. It was believed that this might be strong enough to damage warheads traveling through the layer. This proved not to be

6264-507: The target. Since 2004, the United States Army plans to replace Raytheon 's Patriot missile (SAM) engagement control station (ECS), along with seven other forms of ABM defense command systems, with Integrated Air and Missile Defense Battle Command System (IBCS) designed to shoot down short, medium, and intermediate range ballistic missiles in their terminal phase by intercepting with a hit-to-kill approach. Northrop Grumman

6351-667: The tense situations with China, Taiwan developed the Sky Bow (or Tien-Kung ), this surface-to-air missile can intercept and destroy enemy aircraft and ballistic missiles. These system was created in partnership with Raytheon Technologies , using Lockheed Martin ADAR-HP as inspiration to create the Chang Bai S-band radar system. The missiles have a range of 200 km and was designed to take on fast moving vehicles with low radar cross-section. The latest variant of this system

6438-463: The test and dozens done before reflects China's improvement in the area. Rumored midcourse missiles: The Aster is a family of missiles jointly developed by France and Italy . The Aster 30 variants are capable of ballistic missile defense. An export customer, the United Kingdom also operates the Aster 30 Block 0. On 18 October 2010, France announced a successful tactical ABM test of

6525-578: The two remaining bases continued until 1974, when an additional agreement limited both countries to a single ABM site. The Montana site was abandoned with the main radar partially completed. The remaining base in North Dakota, the Stanley R. Mickelsen Safeguard Complex , became active on 1 April 1975 and fully operational on 1 October 1975. By that time the House Appropriations Committee had already voted to deactivate it. The base

6612-464: Was a two-layer defense system. The long-range Spartan missile would attempt interception outside the Earth's atmosphere. The missile's long range allowed protection of a large geographic area. If the Spartan failed to intercept the incoming offensive missile, the high performance and high speed but short ranged Sprint missile would attempt an interception within the atmosphere. Both missiles used nuclear warheads, and they relied on destroying or damaging

6699-519: Was also proposed. Despite the development of missiles, the programme was slowed down due to financial and political reasons. It was finally closed down during 1980 under a new leadership of Deng Xiaoping as it was seemingly deemed unnecessary after the 1972 Anti-Ballistic Missile Treaty between the Soviet Union and the United States and the closure of the US Safeguard ABM system. In March 2006, China tested an interceptor system comparable to

6786-471: Was completed on 14 March 1969 and announced in a lengthy speech made by Nixon and various DoD advisers. The entire concept was reviewed and all possibilities considered fresh. Among these, the idea of a heavyweight Nike-X-like system was considered, but Defense Secretary Melvin Laird apparently came to the same conclusion as McNamara before him, stating that the protection the system offered simply didn't justify

6873-592: Was enormous. Looking for alternatives, the Sentinel program offered a lightweight cover that would protect against limited attacks. Sentinel began construction in 1968 but ran into a firestorm of protest over its bases being placed in suburban areas. In March 1969, incoming President Richard M. Nixon announced that Sentinel would be cancelled and redirected to protect the missile farms, and that its bases would be placed well away from any civilian areas. The debate about ABM protection of US ICBMs had been going on for over

6960-577: Was established from 1969 for the purpose of developing Project 640. The project was to involve at least three elements, including the necessary sensors and guidance/command system, the Fan Ji (FJ) missile interceptor, and the XianFeng missile-intercepting cannon. The FJ-1 had completed two successful flight tests during 1979, while the low-altitude interceptor FJ-2 completed some successful flight tests using scaled prototypes. A high altitude FJ-3 interceptor

7047-421: Was no reason to deploy a system that only worked under contrived circumstances, especially as accepting them as possibilities meant that the enemy was ignoring your deterrent. If that was the case, why have missiles at all? The real issue becomes ensuring they cannot ignore your deterrent, and it was this concept that Nixon chose. Instead of deploying the ABM system to protect cities, the new deployment would protect

7134-563: Was repeated on 11 February 2007. The Arrow 3 system is capable of exo-atmosphere interception of ballistic missiles, including of ICBMs . It also acts as an anti-satellite weapon. Lieutenant General Patrick J. O'Reilly, Director of the US Missile Defense Agency , said: "The design of Arrow 3 promises to be an extremely capable system, more advanced than what we have ever attempted in the U.S. with our programs." On 10 December 2015 Arrow 3 scored its first intercept in

7221-637: Was selected as the prime contractor in 2010; the Army spent $ 2.7 billion on the program between 2009 and 2020. IBCS engagement stations will support identification and tracking of targets using sensor fusion from disparate data streams, and selection of appropriate kill vehicles from available launcher systems. In February 2022 THAAD radar and TFCC (THAAD Fire Control & Communication) demonstrated their interoperability with Patriot PAC-3 MSE missile launchers, engaging targets using both THAAD and Patriot interceptors. Procurement of MIM-104 Patriot and indigenous Tien-Kung anti-ballistic missile systems. With

7308-463: Was shut down on 10 February 1976. An anti-ICBM defensive ABM system was first considered by the US Army in 1955 under the name Nike II. This was essentially an upgraded version of their Nike B surface-to-air missile (SAM) along with dramatically improved radars and computers able to detect the incoming reentry vehicles (RVs) and develop tracking information while still leaving enough time for

7395-427: Was the control of the Safeguard system. It housed the computers and a phased array radar necessary to track and hit back at incoming ICBM warheads. The radar building itself is a pyramid structure several stories tall. Construction was begun in both Montana and North Dakota, but only the North Dakota site remains standing. The MSR complex included 30 Spartan missile launchers and 16 Sprint missile launchers. Remnants of

7482-471: Was the ultimate development of an ever-changing series of designs produced by Bell Labs that started in the 1950s with the LIM-49 Nike Zeus . By 1960 it was clear that Zeus offered almost no protection against a sophisticated attack using decoys. A new design emerged, Nike-X , with the ability to defend against attacks with hundreds of warheads and thousands of decoys, but the cost of the system

7569-598: Was upgraded during the 1980s to a two-layer system, the A-135 . The Gorgon (SH-11/ABM-4) long-range missile was designed to handle intercepts outside the atmosphere, and the Gazelle (SH-08/ABM-3) short-range missile endoatmospheric intercepts that eluded Gorgon. The A-135 system is considered to be technologically equivalent to the United States Safeguard system of 1975. Safeguard Program Safeguard
