67-462: Kura Missile Test Range (Russian: Ракетный полигон Кура́ ), originally known as Kama , is a Russian intercontinental ballistic missile impact area located in northern Kamchatka Krai in the Russian Far East . It is the destination for ballistic missiles which are test fired from other centers, and was chosen due to its remoteness and distance. It is 130 kilometers (81 mi) northeast of
134-438: A ballistic missile deploys multiple warheads above a single aimpoint which then drift apart, producing a cluster bomb-like effect. These warheads are not individually targetable. The advantage of an MRV over a single warhead is the increased effectiveness due to the greater coverage; this increases the overall damage produced within the center of the pattern, making it far greater than the damage possible from any single warhead in
201-657: A combination of warheads and massive amounts of countermeasures designed to defeat anti-missile systems ; it was announced by the Russian military as a response to the US Prompt Global Strike . In July 2023, North Korea fired a suspected intercontinental ballistic missile that landed short of Japanese waters. The launch follows North Korea's threat to retaliate against the US for alleged spy plane incursions. The following flight phases can be distinguished: ICBMs usually use
268-484: A covert purpose to map mass concentrations and determine local gravity anomalies , in order to improve accuracies of ballistic missiles. Accuracy is expressed as circular error probable (CEP). This is the radius of the circle that the warhead has a 50 percent chance of falling into when aimed at the center. CEP is about 90–100 m for the Trident II and Peacekeeper missiles. A multiple re-entry vehicle (MRV) system for
335-611: A large-scale exercise to check the readiness of its strategic forces. The Strategic Rocket Forces conducted two ICBM launches – a Topol missile was launched from the Plesetsk test site and an R-36M2 (RS-10V/SS-18) missile from a silo in Dombarovskiy. Both missiles delivered their warheads to the Kura test site in Kamchatka. Previous impact was recorded at 10:15 (06:15 GMT) on Wednesday 23 May 2012 when
402-605: A miniaturized physics package and a lower mass re-entry vehicle, both of which are highly advanced technologies. As a result, single-warhead missiles are more attractive for nations with less advanced or less productive nuclear technology. The United States first deployed MRV warheads on the Polaris A-3 SLBM in 1964 on the USS Daniel Webster . The Polaris A-3 missile carried three warheads each having an approximate yield of 200 kilotonnes of TNT (840 TJ). This system
469-455: A minimal independent nuclear deterrent entering its own cold war after an ideological split with the Soviet Union beginning in the early 1960s. After first testing a domestic built nuclear weapon in 1964, it went on to develop various warheads and missiles. Beginning in the early 1970s, the liquid fuelled DF-5 ICBM was developed and used as a satellite launch vehicle in 1975. The DF-5, with
536-641: A network of binary addition circuits that continually recalculate the missile's position. The inputs to the navigation circuit are set by a general-purpose computer according to a navigational input schedule loaded into the missile before launch. One particular weapon developed by the Soviet Union ;– the Fractional Orbital Bombardment System – had a partial orbital trajectory, and unlike most ICBMs its target could not be deduced from its orbital flight path. It
603-459: A new Oreshnik intermediate-range ballistic missile , striking Dnipro . Analysts stated the missile used a multiple independently targetable reentry vehicle (MIRV), likely marking their first use in combat. The night attack was reported to see six sequential vertical flashes, each comprising a cluster of up to six individual projectiles. Ukraine's air force initially claimed an intercontinental ballistic missile (range greater than 5,500 km)
670-537: A new as yet unnamed ballistic missile designed to evade the US missile shield was tested. The missile was fired from a mobile launcher on the Plesetsk range. The warhead was delivered successfully to its designated area on the Kura range on Kamchatka. A Bulava missile, launched from submarine Dimitri Donskoi , landed at Kura in October 2010. Test launches of R-29RMU Sineva and RT-2PM2 Topol-M missiles also frequently target
737-611: A range of 10,000 to 12,000 km (6,200 to 7,500 mi)—long enough to strike the Western United States and the Soviet Union—was silo deployed, with the first pair in service by 1981 and possibly twenty missiles in service by the late 1990s. China also deployed the JL-1 Medium-range ballistic missile with a reach of 1,700 kilometres (1,100 mi) aboard the ultimately unsuccessful Type 092 submarine . In 1991,

#1732845285297804-518: A ready state. Failure rates were very high throughout the early years of ICBM technology. Human spaceflight programs ( Vostok , Mercury , Voskhod , Gemini , etc.) served as a highly visible means of demonstrating confidence in reliability, with successes translating directly to national defense implications. The US was well behind the Soviets in the Space Race and so US President John F. Kennedy increased
871-467: 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. Pakistan is the only nuclear-armed state that does not possess ICBMs. Early ICBMs had limited precision , which made them suitable for use only against
938-513: A single reentry vehicle system, as part of its obligations under the New START treaty. The military purpose of a MIRV is fourfold: MIRV land-based ICBMs were considered destabilizing because they tended to put a premium on striking first . The world's first MIRV—US Minuteman III missile of 1970—threatened to rapidly increase the US's deployable nuclear arsenal and thus the possibility that it would have enough bombs to destroy virtually all of
1005-609: Is an exoatmospheric ballistic missile payload containing several warheads , each capable of being aimed to hit a different target. The concept is almost invariably associated with intercontinental ballistic missiles carrying thermonuclear warheads , even if not strictly being limited to them. An intermediate case is the multiple reentry vehicle (MRV) missile which carries several warheads which are dispersed but not individually aimed. All nuclear-weapon states except Pakistan and North Korea are currently confirmed to have deployed MIRV missile systems. The first true MIRV design
1072-552: Is because of their first-strike capability that land-based MIRVs were banned under the START II agreement. START II was ratified by the Russian Duma on 14 April 2000, but Russia withdrew from the treaty in 2002 after the US withdrew from the ABM treaty . In a MIRV, the main rocket motor (or booster ) pushes a "bus" into a free-flight suborbital ballistic flight path. After the boost phase,
1139-655: Is believed to have deployed a road mobile nuclear ICBM, the Jericho III , which entered service in 2008; an upgraded version is in development. India successfully test fired Agni V , with a strike range of more than 5,000 km (3,100 mi) on 19 April 2012, claiming entry into the ICBM club. The missile's actual range is speculated by foreign researchers to be up to 8,000 km (5,000 mi) with India having downplayed its capabilities to avoid causing concern to other countries. On 15 December 2022, first night trial of Agni-V
1206-409: Is crucial because doubling the accuracy decreases the needed warhead energy by a factor of four for radiation damage and by a factor of eight for blast damage. Navigation system accuracy and the available geophysical information limits the warhead target accuracy. Some writers believe that government-supported geophysical mapping initiatives and ocean satellite altitude systems such as Seasat may have
1273-526: Is no rocket exhaust or other emissions to mark its position to defenders. The high speeds of the warheads make them difficult to intercept and allow for little warning, striking targets many thousands of kilometers away from the launch site (and due to the possible locations of the submarines: anywhere in the world) within approximately 30 minutes. Many authorities say that missiles also release aluminized balloons, electronic noisemakers, and other decoys intended to confuse interception devices and radars . As
1340-446: The Arrow missile in 1998, but it is mainly designed to intercept shorter-ranged theater ballistic missiles, not ICBMs. The Alaska-based United States national missile defense system attained initial operational capability in 2004. ICBMs can be deployed from multiple platforms: The last three kinds are mobile and therefore hard to detect prior to a missile launch. During storage, one of
1407-503: The LGM-30 Minuteman , Polaris and Skybolt . Modern ICBMs tend to be smaller than their ancestors, due to increased accuracy and smaller and lighter warheads, and use solid fuels, making them less useful as orbital launch vehicles. The Western view of the deployment of these systems was governed by the strategic theory of mutual assured destruction . In the 1950s and 1960s, development began on anti-ballistic missile systems by both

#17328452852971474-556: The Soviet Union's nuclear weapons and negate any significant retaliation. Later on the US feared the Soviet's MIRVs because Soviet missiles had a greater throw-weight and could thus put more warheads on each missile than the US could. For example, the US MIRVs might have increased their warhead per missile count by a factor of 6 while the Soviets increased theirs by a factor of 10. Furthermore,
1541-464: The Strategic Air Command 's (SAC) arsenal and replace them with the new Minuteman IIIs outfitted with a MIRV payload, increasing their overall effectiveness. The smaller power of the warheads used (W62, W78 and W87) was offset by increasing the accuracy of the system, allowing it to attack the same hard targets as the larger, less accurate, W56. The MMIII was introduced specifically to address
1608-494: The USSR /Russia preferred ICBM designs that use hypergolic liquid fuels, which can be stored at room temperature for more than a few years. Once the booster falls away, the remaining "bus" releases several warheads, each of which continues on its own unpowered ballistic trajectory , much like an artillery shell or cannonball. The warhead is encased in a cone-shaped reentry vehicle and is difficult to detect in this phase of flight as there
1675-464: The cryogenic fuel liquid oxygen boiled off and caused ice formation, and therefore fueling the rocket was necessary before launch. This procedure was a source of significant operational delay and might allow the missiles to be destroyed by enemy counterparts before they could be used. To resolve this problem Nazi Germany invented the missile silo that protected the missile from Strategic Bombing and also hid fueling operations underground. Although
1742-409: The 32-metre-tall (105 ft) Unha-3 rocket. The United States claimed that the launch was in fact a way to test an ICBM. (See Timeline of first orbital launches by country .) In early July 2017, North Korea claimed for the first time to have tested successfully an ICBM capable of carrying a large thermonuclear warhead. In July 2014, China announced the development of its newest generation of ICBM,
1809-907: The A9/A10 rocket was tested a few times in January and February 1945. After the war, the US executed Operation Paperclip , which took von Braun and hundreds of other leading Nazi scientists to the United States to develop IRBMs , ICBMs, and launchers for the US Army. This technology was predicted by US General of the Army Hap Arnold , who wrote in 1943: Someday, not too distant, there can come streaking out of somewhere – we won't be able to hear it, it will come so fast – some kind of gadget with an explosive so powerful that one projectile will be able to wipe out completely this city of Washington. After World War II,
1876-692: The American missile defense batteries in California and Alaska. New development of ICBM technology are ICBMs able to carry hypersonic glide vehicles as a payload such as RS-28 Sarmat . On 12 March 2024 India announced that it had joined a very limited group of countries, which are capable of firing multiple warheads on a single ICBM. The announcement came after successfully testing multiple independently targetable reentry vehicle (MIRV) technology. [REDACTED] Russia [REDACTED] Russia [REDACTED] Russia [REDACTED] Russia Russia,
1943-646: The Americans and Soviets. Such systems were restricted by the 1972 Anti-Ballistic Missile Treaty . The first successful ABM test was conducted by the Soviets in 1961, which later deployed a fully operational system defending Moscow in the 1970s (see Moscow ABM system ). The 1972 SALT treaty froze the number of ICBM launchers of both the Americans and the Soviets at existing levels and allowed new submarine -based SLBM launchers only if an equal number of land-based ICBM launchers were dismantled. Subsequent talks, called SALT II, were held from 1972 to 1979 and actually reduced
2010-511: The Americans and the Soviets started rocket research programs based on the V-2 and other German wartime designs. Each branch of the US military started its own programs, leading to considerable duplication of effort. In the Soviet Union, rocket research was centrally organized although several teams worked on different designs. The US initiated ICBM research in 1946 with the RTV-A-2 Hiroc project. This
2077-665: The Atlas. Due to the improvements in engine technology and guidance systems the Titan I overtook the Atlas. In the Soviet Union, early development was focused on missiles able to attack European targets. That changed in 1953, when Sergei Korolyov was directed to start development of a true ICBM able to deliver newly developed hydrogen bombs. Given steady funding throughout, the R-7 developed with some speed. The first launch took place on 15 May 1957 and led to an unintended crash 400 km (250 mi) from

2144-509: The Dongfeng-41 ( DF-41 ), which has a range of 12,000 kilometres (7,500 miles), capable of reaching the United States, and which analysts believe is capable of being outfitted with MIRV technology. Most countries in the early stages of developing ICBMs have used liquid propellants, with the known exceptions being the Indian Agni-V , the planned but cancelled South African RSA-4 ICBM, and
2211-495: The Kura Missile Test Range. The Kura range attracted intense interest from United States intelligence agencies in 1957. There was early speculation that missiles were being launched from this range, but this was settled by information from Lockheed U-2 missions in summer 1957 which flew directly over the range and could find no launch infrastructure. The study noted that impacts in the nearby water were likely, and that
2278-498: The MRV cluster; this makes for an efficient area-attack weapon and makes interception by anti-ballistic missiles more challenging due to the number of warheads being deployed at once. Improved warhead designs allow smaller warheads for a given yield, while better electronics and guidance systems allow greater accuracy. As a result, MIRV technology has proven more attractive than MRV for advanced nations. Multiple-warhead missiles require both
2345-535: The Soviet construction of an anti-ballistic missile (ABM) system around Moscow; MIRV allowed the US to overwhelm any conceivable ABM system without increasing the size of their own missile fleet. The Soviets responded by adding MIRV to their R-36 design, first with three warheads in 1975, and eventually up to ten in later versions. While the United States phased out the use of MIRVs in ICBMs in 2014 to comply with New START , Russia continues to develop new ICBM designs using
2412-455: The Soviet testing of their first thermonuclear weapon , but it was not until 1954 that the Atlas missile program was given the highest national priority. The Atlas A first flew on 11 June 1957; the flight lasted only about 24 seconds before the rocket exploded. The first successful flight of an Atlas missile to full range occurred 28 November 1958. The first armed version of the Atlas, the Atlas D,
2479-509: The Soviets were expected to install sonic detection systems to measure water impacts. The missions revealed a regiment of seven Mil Mi-4 helicopters based at Klyuchi which provided logistical support for the range. Up to 1994, the United States maintained Eareckson Air Station (formerly Shemya Air Force Base) only 935 km (581 mi) away, equipped with radars and aircraft to monitor impacts at Kura. One of these radars, Cobra Dane ,
2546-414: The US had a much smaller proportion of its nuclear arsenal in ICBMs than the Soviets. Bombers could not be outfitted with MIRVs so their capacity would not be multiplied. Thus the US did not seem to have as much potential for MIRV usage as the Soviets. However, the US had a larger number of submarine-launched ballistic missiles , which could be outfitted with MIRVs, and helped offset the ICBM disadvantage. It
2613-608: The United States and the Soviet Union agreed in the START I treaty to reduce their deployed ICBMs and attributed warheads. As of 2016 , all five of the nations with permanent seats on the United Nations Security Council have fully operational long-range ballistic missile systems; Russia, the United States, and China also have land-based ICBMs (the US missiles are silo-based, while China and Russia have both silo and road-mobile ( DF-31 , RT-2PM2 Topol-M missiles). Israel
2680-955: The United States, China, North Korea, India and Israel are the only countries currently known to possess land-based ICBMs. The United States currently operates 405 ICBMs in three USAF bases. The only model deployed is LGM-30G Minuteman-III . All previous USAF Minuteman II missiles were destroyed in accordance with START II , and their launch silos have been sealed or sold to the public. The powerful MIRV-capable Peacekeeper missiles were phased out in 2005. The Russian Strategic Rocket Forces have 286 ICBMs able to deliver 958 nuclear warheads: 46 silo-based R-36M2 (SS-18) , 30 silo-based UR-100N (SS-19), 36 mobile RT-2PM "Topol" (SS-25) , 60 silo-based RT-2UTTH "Topol M" (SS-27) , 18 mobile RT-2UTTH "Topol M" (SS-27) , 84 mobile RS-24 "Yars" (SS-29), and 12 silo-based RS-24 "Yars" (SS-29).

The Safeguard ABM facility, located in North Dakota, was operational from 1975 to 1976. The Soviets deployed their ABM-1 Galosh system around Moscow in the 1970s, which remains in service. Israel deployed a national ABM system based on

2814-530: The bus maneuvers using small on-board rocket motors and a computerized inertial guidance system . It takes up a ballistic trajectory that will deliver a re-entry vehicle containing a warhead to a target and then releases a warhead on that trajectory. It then maneuvers to a different trajectory, releasing another warhead, and repeats the process for all warheads. The precise technical details are closely guarded military secrets , to hinder any development of enemy counter-measures. The bus's on-board propellant limits
2881-461: The distances between targets of individual warheads to perhaps a few hundred kilometers. Some warheads may use small hypersonic airfoils during the descent to gain additional cross-range distance. Additionally, some buses (e.g. the British Chevaline system) can release decoys to confuse interception devices and radars , such as aluminized balloons or electronic noisemakers. Accuracy
2948-476: The largest targets , such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) demanded the use of a more precise, crewed bomber . Second- and third-generation designs (such as the LGM-118 Peacekeeper ) dramatically improved accuracy to the point where even
3015-573: The most important features of the missile is its serviceability. One of the key features of the first computer-controlled ICBM, the Minuteman missile , was that it could quickly and easily use its computer to test itself. After launch, a booster pushes the missile and then falls away. Most modern boosters are Solid-propellant rocket motors , which can be stored easily for long periods of time. Early missiles used liquid-fueled rocket motors . Many liquid-fueled ICBMs could not be kept fueled at all times as
3082-710: The nearby detonation of friendly warheads), one neutron-resistant material developed for this purpose in the UK is three-dimensional quartz phenolic . Circular error probable is crucial, because halving the circular error probable decreases the needed warhead energy by a factor of four . Accuracy is limited by the accuracy of the navigation system and the available geodetic information. Strategic missile systems are thought to use custom integrated circuits designed to calculate navigational differential equations thousands to millions of FLOPS in order to reduce navigational errors caused by calculation alone. These circuits are usually

The RS-28 Sarmat (Russian: РС-28 Сармат; NATO reporting name : SATAN 2), is a Russian liquid-fueled , MIRV -equipped, super-heavy thermonuclear armed intercontinental ballistic missile in development by the Makeyev Rocket Design Bureau from 2009, intended to replace the previous R-36 missile . Its large payload would allow for up to 10 heavy warheads or 15 lighter ones or up to 24 hypersonic glide vehicles Yu-74 , or
3216-522: The nuclear warhead reenters the Earth's atmosphere, its high speed causes compression of the air, leading to a dramatic rise in temperature which would destroy it, if it were not shielded in some way. In one design, warhead components are contained within an aluminium honeycomb substructure , sheathed in a pyrolytic carbon - epoxy synthetic resin composite material heat shield. Warheads are also often radiation-hardened (to protect against nuclear armed ABMs or
3283-625: The number of nuclear warheads held by the US and Soviets. SALT II was never ratified by the US Senate , but its terms were honored by both sides until 1986, when the Reagan administration "withdrew" after it had accused the Soviets of violating the pact. In the 1980s, President Ronald Reagan launched the Strategic Defense Initiative as well as the MX and Midgetman ICBM programs. China developed
3350-883: The range is administratively under Plesetsk Cosmodrome , and consequently is part of the Russian Space Forces . Kura Missile Testing Range remains active in 2024. An ICBM was launched there on 25 Oct 2023, after the Russian Parliament withdrew from the 1996 Nuclear Test Ban treaty in response to the failure by the USA to ratify the Treaty for 28 years. It was reported that the strategic nuclear submarine Yury Dolgorukiy of Project 955 (Borei) on Wednesday, 29 October 2014 20:27 MSK (17:27 UTC) successfully conducted its fifth launch of Bulava submarine-launched ballistic missile (SLBM) at Kura firing range. On 30 October 2013 Russia conducted
3417-482: The settlement of Klyuchi and the military townlet is called Klyuchi-1, after the nearest settlement. The range was developed beginning in 1955 and was operational in 1957. The first impact occurred on 21 August 1957, and was followed by 136 impacts through 1964. Although the range is a test site for intercontinental ballistic missiles , which are controlled by the Russian Strategic Rocket Forces ,

#17328452852973484-466: The site. The first successful test followed on 21 August 1957; the R-7 flew over 6,000 km (3,700 mi) and became the world's first ICBM. The first strategic-missile unit became operational on 9 February 1959 at Plesetsk in north-west Russia. It was the same R-7 launch vehicle that placed the first artificial satellite in space, Sputnik , on 4 October 1957. The first human spaceflight in history
3551-477: The smallest point targets can be successfully attacked. ICBMs are differentiated by having greater range and speed than other ballistic missiles: intermediate-range ballistic missiles (IRBMs), medium-range ballistic missiles (MRBMs), short-range ballistic missiles (SRBMs) and tactical ballistic missiles . The first practical design for an ICBM grew out of Nazi Germany 's V-2 rocket program. The liquid-fueled V-2, designed by Wernher von Braun and his team,
3618-482: The stakes with the Apollo program , which used Saturn rocket technology that had been funded by President Dwight D. Eisenhower . These early ICBMs also formed the basis of many space launch systems. Examples include R-7 , Atlas , Redstone , Titan , and Proton , which was derived from the earlier ICBMs but never deployed as an ICBM. The Eisenhower administration supported the development of solid-fueled missiles such as
3685-445: The technology. The introduction of MIRV led to a major change in the strategic balance. Previously, with one warhead per missile, it was conceivable that one could build a defense that used missiles to attack individual warheads. Any increase in missile fleet by the enemy could be countered by a similar increase in interceptors. With MIRV, a single new enemy missile meant that multiple interceptors would have to be built, meaning that it
3752-428: The trajectory which optimizes range for a given amount of payload (the minimum-energy trajectory ); an alternative is a depressed trajectory , which allows less payload, shorter flight time, and has a much lower apogee. Modern ICBMs typically carry multiple independently targetable reentry vehicles ( MIRVs ), each of which carries a separate nuclear warhead , allowing a single missile to hit multiple targets. MIRV
3819-432: Was a three-stage effort with the ICBM development not starting until the third stage. However, funding was cut in 1948 after only three partially successful launches of the second stage design, that was used to test variations of the V-2 design. With overwhelming air superiority and truly intercontinental bombers, the newly formed US Air Force did not take the problem of ICBM development seriously. Things changed in 1953 with
3886-509: Was accomplished on a derivative of R-7, Vostok , on 12 April 1961 , by Soviet cosmonaut Yuri Gagarin . A heavily modernized version of the R-7 is still used as the launch vehicle for the Soviet/Russian Soyuz spacecraft , marking more than 60 years of operational history of Sergei Korolyov 's original rocket design. The R-7 and Atlas each required a large launch facility, making them vulnerable to attack, and could not be kept in
3953-763: Was also used by the Royal Navy who also retained MRV with the Chevaline upgrade, though the number of warheads in Chevaline was reduced to two due to the ABM counter-measures carried. The Soviet Union deployed 3 MRVs on the R-27U SLBM and 3 MRVs on the R-36P ICBM. Refer to atmospheric re-entry for more details. On November 21, 2024, as part of the Russian invasion of Ukraine , Russia launched
4020-520: Was an outgrowth of the rapidly shrinking size and weight of modern warheads and the Strategic Arms Limitation Treaties ( SALT I and SALT II ), which imposed limitations on the number of launch vehicles. It has also proved to be an "easy answer" to proposed deployments of anti-ballistic missile (ABM) systems: It is far less expensive to add more warheads to an existing missile system than to build an ABM system capable of shooting down
4087-418: Was declared operational in January 1959 at Vandenberg, although it had not yet flown. The first test flight was carried out on 9 July 1959, and the missile was accepted for service on 1 September. The Titan I was another US multistage ICBM, with a successful launch February 5, 1959, with Titan I A3. Unlike the Atlas, the Titan I was a two-stage missile, rather than three. The Titan was larger, yet lighter, than

However, according to reports, Russia is working on the new Sarmat ICBM which leverages Fractional Orbital Bombardment concepts to use a Southern polar approach instead of flying over the northern polar regions. Using that approach, it is theorized, avoids

Intercontinental ballistic missile 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 (delivering one or more thermonuclear warheads ). 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
4288-449: Was much less expensive to increase the attack than the defense. This cost-exchange ratio was so heavily biased towards the attacker that the concept of mutual assured destruction became the leading concept in strategic planning and ABM systems were severely limited in the 1972 Anti-Ballistic Missile Treaty in order to avoid a massive arms race . In June 2017 the United States finished converting its Minuteman III missiles back to using

The range has been increased to 7,000 km. By 2012 there was speculation by some intelligence agencies that North Korea is developing an ICBM. North Korea successfully put a satellite into space on 12 December 2012 using

The Minuteman III held three smaller W62 warheads, with yields of about 170 kilotons of TNT (710 TJ) each in place of the single 1.2 megatons of TNT (5.0 PJ) W56 used on the Minuteman II. From 1970 to 1975, the United States would remove approximately 550 earlier versions of the Minuteman ICBM in

Under Projekt Amerika, von Braun's team developed the A9/10 ICBM, intended for use in bombing New York and other American cities. Initially intended to be guided by radio, it was changed to be a piloted craft after the failure of Operation Elster . The second stage of
