68-487: The RTV-A-2 Hiroc (high-altitude rocket) was a product of the United States' first effort to develop an intercontinental ballistic missile (ICBM). The project was named MX-774 . The project was canceled in 1947, but leftover funds were used to build and launch three of the planned 10 research vehicles designated RTV-A-2. The design included several innovations; the gimbaled thrust chambers provided guidance control,
136-559: A fin span (the maximum width of the rocket, accounting for the fins) of 6 feet 10 inches (2.08 m), a diameter of 30 inches (760 mm), an empty weight including payload of 1,205 pounds (547 kg) and a gross liftoff weight (GLOW) of 4,090 pounds (1,860 kg). The missile's propulsion system consisted of an XLR35-RM-1 composed of four thrust chambers, built by Reaction Motors , which produced 2,000 lbf (8.9 kN ) of thrust each and could independently swivel up to ten degrees on one axis. The gimbaling motion

272-502: A camera and some instruments survived. During the test on 2 December, the Hiroc reached a maximum height of 30 miles (48 km) and reached a maximum velocity of 2,653 feet per second (809 m/s). The parachute failed to open yet again, this time due to the nose cone damaging it after being ejected, while the Hiroc was at an altitude of 121,000 feet (37,000 m) and moving at a speed of 1,500 feet per second (460 m/s). The camera
340-675: 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
408-461: 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
476-664: 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
544-628: 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,
612-529: 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
680-474: 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
748-472: A total of 150,000 lbf (670 kN) of thrust, compared to the Hiroc's total of 8,000 lbf (36 kN) thrust. In April 1946, Convair received a 1.9 million dollar contract from the US Government under Air Material Command designation Material, Experimental-774B (MX-774B) to investigate the development of ballistic missiles. This was one of a large number of missile projects being studied by

#1732781074541816-763: Is a United States Army military testing area and firing range located in the US state of New Mexico . The range was originally established in 1941 as the Alamogordo Bombing and Gunnery Range , where the Trinity test site lay at the northern end of the Range, in Socorro County near the towns of Carrizozo and San Antonio . It then became the White Sands Proving Ground on 9 July 1945. White Sands National Park founded in
884-428: 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

El Paso International Airport is the nearest airport with regularly scheduled commercial flights. There have been no regularly scheduled commercial passenger flights from Las Cruces International Airport since 25 July 2005, when Westward Airways ceased operations; general aviation, New Mexico Army National Guard (4 UH-72 Lakota Helicopters), private charters and CAP, among others, still use
1020-665: 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
1088-526: 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
1156-450: 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
1224-559: The Atlas rockets . Several changes were made in the Atlas, such as the aluminum used for the missiles airframe of the Hiroc, was changed to stainless steel in the Atlas. The early Atlas utilized the MX-774 project developed Azusa interferometry based guidance system which served Cape Canaveral during the early space age. The engines of the Atlas missiles were also much more powerful, generating
1292-511: 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

The original of MX-774B called for a missile that could deliver a 5,000 pounds (2,300 kg) payload 5,000 miles (8,000 km), and which had an accuracy that allowed it to deliver it to within 5,000 feet (1,500 m) of the target. The MX-774B project was headed by Karel Bossart , who would go on to head
1564-498: 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
1632-464: 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

1768-409: 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,
1836-872: 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,

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,
1972-651: 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
2040-521: 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
2108-624: 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

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,
2312-685: 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
2380-907: 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).

This made the rocket lighter as only the nose cone and its instruments and recording camera had to be able to survive recovery, rather than the entire rocket. The unique innovations of the Hiroc missiles, such as the gimbaled thrust chambers, and the internal pressure supported airframe, would go on to be utilized in

Tracking was provided Askania Cine theodolite, cameras, Sky-screen observers and four tracking telescopes and tracking radar. White Sands Proving Ground provided housing and support for the launch program. On the RTV-A-2 (MX-774), a camera recorded the flight data displayed upon an instrument panel. Both
2788-628: The creation of the Atlas rockets. Although development of the specification MX-774B was inspired by the German V-2 the MX-774B introduced several significant innovations, such as an integrated propellant tank, swiveling engines, pressurized body, and detachable nose cone. As a result of drastic defense cuts in 1946 and for 1947 the USAAF's missile budget was cut in half from $ 29 to $ 13 million in what became known as "the black Christmas of 1946". Many of

In late 1948 the Air Force proposed the continuation of the MX-774 program with an additional 15 missiles for high altitude research but the proposal was refused by the Research and Development Board's Committee on Guided Missiles which decided that the more capable Navy Viking Missile RTV-N-12
2924-623: The internal gas pressure was used to support the airframe and the nose cap was separable. All of these concepts were later used on the Atlas missile and the first two on the Viking rocket . Also developed as part of MX-774 was the Azusa guidance system which was not used on the Hiroc missile but did contribute to the Atlas missile as well as many other early guided missiles launched from Cape Canveral. The Hiroc missiles were 31.5 feet (9.6 m) long, had
2992-485: 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
3060-578: 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
3128-713: 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
3264-526: 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
3332-649: 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
3400-405: The number of parameters recorded and the survivability of the film record were limited. Therefore, dependence upon the intact recovery of this camera was problematic. During the test on 13 July, the Hiroc reached a maximum height of 6,200 feet (1,900 m), but lost thrust after 12.6 seconds and hit the ground at 48.5 seconds, 415 feet (126 m) from the launch pad. Due to a mistake in packing,
3468-490: The payload recovery parachute failed to open; a camera and a few other instruments survived, so the test was deemed a partial success. During the test on 27 September, the Hiroc reached an altitude of 24 miles (39 km) at 48 seconds and a maximum velocity of 2,350 feet per second (720 m/s). The parachute failed again, this time due to a battery problem; the Hiroc began to freefall before its oxygen tank exploded at 20,000 feet (6,100 m). This caused it to break up, but

#17327810745413536-609: The projects were canceled outright, but MX-774 instead continued with reduced funding. The project was eventually canceled in June 1947 as the Army concentrated their efforts on cruise missiles, which were more promising at that time. Convair arranged to use the remaining contract funding to launch three of the rockets, which were named RTV-A-2 Hiroc. The tests took place at White Sands Proving Grounds . The three tests took place on 13 July 1947, 27 September, and 2 December. These tests validated
3604-429: The rocket was supported by nitrogen gas pressure inside the tank, which could contain propellant or nitrogen gas when stored. Having gas pressure provide rigidity to the structure reduced the empty weight by requiring less metallic components for structural reinforcement, but made the missile fragile because it required continuous pressurization. The RTV-A-2 Hiroc had an airframe to propellant ratio three times better than

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
3740-477: 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,

WSMR is located between Las Cruces, New Mexico to the west, Alamogordo, New Mexico 40 miles to the east, and Chaparral, New Mexico and El Paso, Texas to the south. White Sands National Park and the San Andres National Wildlife Refuge are federally-protected natural areas contained within
3876-486: 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
3944-428: 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
4012-647: Was a superior high altitude research vehicle. Convair retained the core design team after program cancellation. That core led to Convair proposing a missile to meet the Air Force Request For Proposal MX-1593 which ultimately resulted in the Weapon System 107A, better known as the B-65/SM-65 Atlas, America's first ICBM. Intercontinental ballistic missile An intercontinental ballistic missile ( ICBM )
4080-432: 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
4148-518: 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

#17327810745414216-534: 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
4284-418: 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
4352-416: Was decommissioned in compliance with arms control agreements, which address the maximum range of ICBMs and prohibit orbital or fractional-orbital weapons. 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
4420-443: Was recovered, although it was partly damaged. The third Hiroc had its nose compartment extended 34 inches to allow more instrumentation. All three Hiroc missiles had partially failed due to premature closure of the liquid oxygen valve. The cause of failure was determined from a light on the instrumentation coming on when the valve closed. The cause of the valve closing was traced to vibration of solenoids which caused pressure change in
4488-408: Was successfully carried out by SFC from Abdul Kalam Island, Odisha. The missile is now 20 percent lighter because the use of composite materials rather than steel material. 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
4556-470: Was then widely used by Nazi Germany from mid-1944 until March 1945 to bomb British and Belgian cities, particularly Antwerp and London. 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
