101-568: The Missile Warning Center coordinates, plans, and executes worldwide missile, nuclear detonation, and space re-entry event detection to provide timely, accurate, and unambiguous strategic warning in support of the United States and Canada. During deployment of the computerized air defense network for the United States, the Soviet Union announced that they had successfully tested an ICBM . BMEWS General Operational Requirement 156

202-474: A Lockheed Martin contract "to upgrade all of the mission systems within Cheyenne Mountain, which included the space surveillance systems" for delivery in 2006. The portion of CCIC2S modernizing "attack warning systems within Cheyenne Mountain [was to] cost more than $ 700 million from fiscal years 2000 to 2006", and the delayed CCIC2S upgrades for space surveillance were superseded by systems for

303-651: A skeleton crew and no longer operates on a 24/7 basis. The complex is on "warm standby", meaning it is only staffed when required. On the fiftieth anniversary of the NORAD agreement—May 12, 2008—the Command Center located within Cheyenne Mountain Complex was officially re-designated as the NORAD and USNORTHCOM Alternate Command Center. The Cheyenne Mountain Division of NORAD and USNORTHCOM

404-479: A $ 700 million contract with Raytheon to move systems into the complex to shield it from electromagnetic pulse attack, with additional work to be done at Vandenberg and Offutt . According to Gortney, "because of the very nature of the way that Cheyenne Mountain's built, it's EMP-hardened. And so, there's a lot of movement to put capability into Cheyenne Mountain and to be able to communicate in there". Electronic Systems Division Detachment 10 at Ent AFB became

505-894: A Message Processing Subsystem and a Video Distribution Subsystem, and [to upgrade] the NORAD Computer System display capability and four major centers: (1) the Air Defense Operations Center , (2) the NORAD Command Center, (3) the Battle Staff Support Center, and (4) the Weather Support Unit." It was also to process and display " nuclear detection data provided from the Integrated Correlation and Display System." For $ 230 million

606-626: A US Zone of the Interior facility for anti-ICBM fire control by Air Defense Command (ADC) was for it to be "the heart of the entire ballistic missile defense system" with Nike Zeus SAMs . On 19 October 1959, HQ USAF assigned ADC the "planning responsibility" for eventual operation of the Missile Defense Alarm System to detect ICBM launches with infrared sensors in space. The BMEWS Central Computer and Display Facility (CC&DF) built as an austere facility instead of

707-499: A bad computer chip was updated, and staff and commander processes were improved to better respond to warnings. The Cheyenne Mountain Upgrade (CMU) of November 1988, designed to consolidate five improvement programs, was not installed because it was not compatible with other systems at Cheyenne Mountain and it did not meet the defined specifications according to deficiencies identified during testing. The five improvement programs were

808-675: 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

909-523: A computer chip "went haywire" and issued false missile warnings, which raised the possibility that a nuclear war could be started accidentally, based upon incorrect data. Staff analyzed the data and found that the warnings were erroneous, and the systems were updated to identify false alarms. Gen. James V. Hartinger of the Air Force stated that "his primary responsibility is to provide Washington with what he calls 'timely, unambiguous, reliable warning' that

1010-506: A large quantity of cots for most of the personnel, including suites for high-ranking officers within the bunker. Amenities include a medical facility, store, cafeteria, and fitness centers inside and outside the mountain. The bunker is built to deflect a 30 megaton nuclear explosion as close as 1.2 miles (1.9 km). Within a mountain tunnel are sets of 25-ton blast doors and another for the civil engineering department. The doors were built so that they can always be opened when needed. Should

1111-400: 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

1212-664: 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

1313-547: A nuclear attack. In 1957, the Strategic Air Command began construction in New England inside Bare Mountain for a hardened bunker to contain the command post for the 8th Air Force , which was located at nearby Westover Air Force Base , Chicopee, Massachusetts . This underground facility was nicknamed " The Notch " (or formally as the 8th AF "Post-Attack Command and Control System Facility, Hadley") and

1414-455: A nuclear blast hit the building, they are designed to withstand a blast wave . There is a network of blast valves with unique filters to capture airborne chemical, biological, radiological, and nuclear contaminants. Outside of the military complex are the parking lots, a fire station, and outdoor recreational facilities. The recreational amenities include Mountain Man Park, picnic areas,

1515-420: A racquetball facility, softball field, sand volleyball court, basketball court, a putting green, and horseshoe area. The complex has its own power plant, heating and cooling system, and water supply. The 21st Mission Support Group ensures there is a 99.999% degree of reliability of its electricity, water, air conditioning, power, and other support systems. The threats, in descending order of likelihood, that

1616-466: A raid on North America has begun." He explained that there are about 6,700 messages generated on average each hour in 1979 and 1980 and all had been processed without error. An off-site testing facility was established in Colorado Springs by NORAD in late 1979 or early 1980 so that system changes could be tested off-line before they were moved into production. Following another failure in 1980,

1717-628: 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,

1818-529: 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

1919-474: 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

2020-600: A system integrator and modernized the communications to a major data processing system, was completed in October 1972. The Ballistic Missile Defense Center (BMDC) BW 1.2 release was installed in February 1974 in the Combat Operations Center, under the command of CONAD.

Also located in Colorado Springs is Peterson Space Force Base , where the North American Aerospace Defense Command (NORAD) and United States Northern Command (USNORTHCOM) headquarters are located. Formerly

2323-665: 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

Cheyenne Mountain Air Force Station

2525-526: 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

2626-590: Is owned and operated by Air Force Space Command. NORAD and USNORTHCOM now use just under 30% of the floor space within the complex and comprise approximately 5% of the daily population at Cheyenne Mountain. The Cheyenne Mountain Complex serves as NORAD and USNORTHCOM's Alternate Command Center and as a training site for crew qualification. Day-to-day crew operations for NORAD and USNORTHCOM typically take place at Peterson Air Force Base. In early 2015, Admiral William E. Gortney , commander of NORAD and NORTHCOM, announced

2727-1043: The AN/FPS-129 HAVE STARE (Globus II) radar in California had been upgraded to "relay data to Cheyenne Mountain", and by October 1995 the 1st Command and Control Squadron (1CACS) in the bunker was providing space collision avoidance data to the Cheyenne Mountain Operations Center's space control center. In June 1993, the Cheyenne Mountain Complex Operations Center had the USSPACE and NORAD Command Center, NORAD Air Defense Operations Center (ADOC), NORAD/USSPACECOM Combined Intelligence Watch Center (CIWC), USSPACECOM Space Defense Operations Center (SPADOC), USSPACECOM Space Surveillance Center (SSC), AFSPACECOM Weather Operations Center, and

2828-450: 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

2929-826: The Cheyenne Mountain nuclear bunker ( FOC of the new bunker's command center—a portion of the Burroughs 425L Command/Control and Missile Warning System —had been on July 1, 1966.) Interim operations of the Avco 474N SLBM Detection and Warning System began in July 1970 (IOC was 5 May 1972), and in 1972 20% of the Bendix AN/FPS-85 Phased Array Radar 's surveillance capability "became dedicated to search for SLBMs" (the FPS-85 relayed SLBM data via

3030-637: The Joint Space Operations Center 's Space C2 program and Integrated Space Situational Awareness program. By 2003, consoles for the Ground-Based Mid-Course Defense (GMD) had been contracted for Cheyenne Mountain, and the planned 18 month Cheyenne Mountain Realignment to move Command Center operations to Peterson AFB was complete by May 13, 2008. On August 3, 2011, a ribbon cutting was held for

3131-511: 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

3232-718: The National Civil Defense Warning Center was in the bunker. System Development Corporation updated Air Defense Command satellite information processing systems for $ 15,850,542 on January 19, 1973. The improvements were primarily to the Space Computational Center's displays and application software, which was updated to provide real-time positioning of orbiting space systems for the NORAD Combat Operation Center. The first phase, which established

3333-650: The Satellite Intercept System which would use orbit data from a Space Defense Center . By December 15, 1964, NORAD had an implementation plan for a "Single Integrated Space Defense Center" for NORAD/CONAD to centralize both missile warning and space surveillance. The 1st Aero on February 6, 1967, moved operations to the Group III Space Defense Center , the integrated missile warning/space surveillance facility (496L Spacetrack system with Philco 212 primary processor) at

3434-910: The Space Control Center which AFSPC was moving from Cheyenne Mountain to Vandenberg .) In May 2010, USSTRATCOM decided to keep its missile warning center at Cheyenne Mountain, which had begun a $ 2.9 million renovation in January 2010 (a temporary MWOC facility had to be set up.) ICBM 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

3535-498: 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

3636-464: 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

3737-579: The surveillance center in New Hampshire "was discontinued as the new SPADATS Center became operational at Ent AFB" with the 496L Space Detection and Tracking System (i.e., NORAD began aerospace operations). In 1962 the Army's LIM-49 Nike Zeus program was assigned the satellite intercept mission ( Program 505's "Operation Mudflap " conducted a test), and the 1962 SECDEF assigned the USAF to develop

3838-791: The " Joint Task Force – Cheyenne Mountain Operations organization was brought online to take responsibility for the installation", Brig. Gen. Donald Peterson was the commander of the JTF, which was renamed the " U.S. Space Command Cheyenne Mountain operations center" by March 1995. On July 28, 2006, the Cheyenne Mountain Realignment redesignated the Cheyenne Mountain Directorate to the Cheyenne Mountain Division. Circa 2004

3939-565: The "missile and space surveillance and warning system" consisted of a space computational center and 5 sensor systems: By 1981 Cheyenne Mountain was providing 6,700 messages per hour compiled via sensor inputs from the Joint Surveillance System , BMEWS, the SLBM "Detection and Warning System, COBRA DANE , and PARCS as well as SEWS and PAVE PAWS ". During the 1991 Gulf War , the missile operations section that supported

4040-825: The 1970s. In 1979, the Cheyenne Mountain Complex Improvements Program 427M system became fully operational. It was a consolidated Cheyenne Mountain Upgrade program for command center, space, ballistic missile, and space functions, developed using new software technology and designed for computers with large processing capacity. There were three major segments of the 427M system: the Communication System Segment (CSS), NORAD Computer System (NCS), and Space Computational Center (SCC). The 425L Command and Control System, Display Information Processor, Command Center Processing System, and other hardware were replaced by

4141-409: 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,

4242-653: The 474N network for SLBM warning to " SAC , the National Military Command Center , and the Alternate NMCC over BMEWS circuits"). The NORAD/CONAD Missile Warning Center came under NORAD/ADCOM control in 1975 when the unified Continental Air Defense Command ended and in early 1972, the 427M improvement program was planned; e.g., ( NORAD Computer System to replace the 425L System.) After SAC assumed control of ballistic missile warning and space surveillance facilities on December 1, 1979,

4343-817: 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,

4444-545: The AFSPACECOM Systems Center within its facility. Plans to house the USSPACECOM and NORAD command centers in the same location began by July 1994. A $ 450 million upgrade was made to the missile warning center beginning in February 1995. The effort was part of a $ 1.7 billion renovation program for Cheyenne Mountain. 'Granite Sentry' was an improvement program for the complex. It aimed "to provide

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

4747-521: 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

4848-676: 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

4949-649: The Battle Staff Support Center. The Space Defense Operations Center (SPADOC), established on October 1, 1979, consolidated United States Air Force satellite survivability, space surveillance, and US ASAT operations into one wartime space activities hub at the NORAD Cheyenne Mountain Complex. Space surveillance and missile warning functions were performed by the Core Processing Segment (CPS) using Worldwide Military Command and Control System 's Honeywell H6080 computers at

5050-814: The CCPDS Replacement (CCPDS-R), CSS Replacement (CSS-R), Granite Sentry upgrade, SCIS, and SPADOC 4. SPADOC 4 was for upgrading the SCC with primary and backup 3090-200J mainframes ), and SPADOC 4 block A achieved initial operating capability (IOC) in April 1989. The CSS-R "first element" achieved IOC on April 12, 1991; and the 427M system was replaced c.  1992 . The CSSR, SCIS, Granite Sentry, CCPDS-R, and their interfaces were tested in 1997. Testing of Granite Sentry nuclear detonation (NUDET) data processing system found it to be inadequate. The Joint Surveillance System (JSS), developed under an agreement with

The Space and Warning Systems Center maintained "26 stovepipe systems" for USSPACECOM , NORAD, and AFSPC , and the Space Computational Center was replaced in 1992. In February 1995, "the missile warning center at Cheyenne Mountain AS [was] undergoing a $ 450 million upgrade program as part of Cheyenne Mountain's $ 1.7 billion renovation package." At Cheyenne Mountain on September 11, 2001, Major Richard J. Hughes

5858-560: The MWC was in the same room as HQ NORAD/ADCOM J31's Space Surveillance Center (separated by partitions.) The "NORAD Missile Warning and Space Surveillance System " was the general term for the entire network applied by the House's 1981 Armed Services Committee —the Core Processing Segment (CPS) handled missile warning/space surveillance with three Honeywell H6080 computers, e.g., a NORAD Computer System (NCS) H6080 for command and control and for missile warning functions (2nd for space surveillance and 3rd as backup for both). Circa 1986,

5959-424: The NORAD Combat Operations Center beginning on May 18, 1961, by Utah Construction & Mining Company . The Space Defense Center and the Combat Operations Center achieved full operational capability on February 6, 1967. The total cost was $ 142.4 million. Its systems included a command-and-control system developed by Burroughs Corporation . The electronics and communications system centralized and automated

6060-412: The NORAD Computer System (NCS). The new system was designed to centralize several databases, improve on-line display capabilities, and consolidate mission warning information processing and transmission.

In 2006, NORAD relocated to a basement in the Peterson No. 2 building at the nearby Peterson AFB . Northern Command and Space Command and Canadian military defense partners relocated at Peterson. The Cheyenne Mountain complex is maintained by

6666-488: 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

6767-909: 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).

6868-420: The additional warheads; hence, most ABM system proposals have been judged to be impractical. The first operational ABM systems were deployed in the United States during the 1970s. 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

6969-400: The base requires, and a 1,500,000-gallon (5,700,000-litre) reservoir ensures that even in event of fire, there is enough water to meet the facility's needs. A reservoir of 4,500,000 gallons (17,000,000 litres) of water is used as a heat sink. There is a "massive" reservoir for diesel fuel and a "huge" battery bank with redundant power generators. The North American Air Defense Command (NORAD)

7070-417: The bunker and in 1992, an airman of the "1010th Civil Engineering Squadron at Cheyenne Mountain Air Force Base" developed a 3-D AutoCAD model of the bunker "to zoom in on a specific room". By 1995 a "missile operations section" supported the missile warning center, and in 2001 the 1989 1CACS at the Cheyenne Mountain Air Force Station was renamed the 1st Space Control Squadron . On June 24, 1994, when

7171-476: The center for the United States Space Command (USSC) and NORAD, the Complex monitored the airspace of Canada and the United States for missiles, space systems, and foreign aircraft through its worldwide early-warning system. Since 2008, NORAD and the USSC have been based at Peterson Space Force Base and the complex, re-designated as an Air Force station, is used for crew training and as a back-up command center if required. The military complex has included, in

7272-409: The complex may face are "medical emergencies, natural disasters, civil disorder, a conventional attack, an electromagnetic pulse attack, a cyber or information attack, chemical or biological or radiological attack, an improvised nuclear attack, a limited nuclear attack, [and] a general nuclear attack." The least likely events are the most hazardous. There is more water produced by mountain springs than

7373-599: The instantaneous (one-millionth of a second) evaluation of aerospace surveillance data. The Space Defense Center moved from Ent AFB to the complex in 1965. The NORAD Combat Operations Center was fully operational April 20, 1966 and The Space Defense Command's 1st Aerospace Control Squadron moved to Cheyenne Mountain that month. The following systems or commands became operational between May and October, 1966: The NORAD Attack Warning System, Combat Operations Command, and Delta I computer system, which recorded and monitored every detected space system. By January 4, 1967,

7474-485: 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

7575-578: 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

7676-713: 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

7777-566: The now in service Israeli Jericho III . 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

7878-526: 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

7979-649: 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

8080-555: The past, many units of NORAD, USSC, Aerospace Defense Command (ADCOM), Air Force Systems Command , Air Weather Service, and the Federal Emergency Management Agency (FEMA). The complex's communication center is also used by the nearby U.S. Civil Defense Warning Center. The complex was built under 2,000 feet (610 metres) of granite on five acres (2 hectares). Fifteen three-story buildings are protected from movement, e.g., earthquake or explosion, by

8181-698: The planned AICBM control center became operational on September 30, 1960, at Ent AFB when BMEWS ' Thule Site J became operational. Site J's computers (e.g., in the Sylvania AN/FSQ-28 Missile Impact Predictor Set ) processed 4 RCA AN/FPS-50 Radar Sets ' data, and alerts transferred via the BMEWS Rearward Communications System to the CC&;DF for NORAD attack assessment and warning to RCA Display Information Processors (DIPs) at

8282-677: The program was also to "replace display screens of the Attack Warning and Attack Assessment System." It was delayed from 1993 to 1996. Granite Sentry and other Cheyenne Mountain Upgrade interfaces were tested in 1997, and Granite Sentry's processing regarding "simulated [nuclear] detonation messages…injected into the Defense Support Program Data Distribution Center [was] not adequate...". The Combatant Commander's Integrated Command and Control System (CCIC2S) program began in 2000 with

8383-469: 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

8484-477: 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,

8585-486: 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

8686-428: 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

8787-432: 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

8888-518: 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

8989-534: 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

9090-418: 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

9191-416: 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

9292-541: Was established and activated at the Ent Air Force Base on September 12, 1957. The Command is a binational organization of Canadian ( 1 Canadian Air Division ) and United States air defense command units, in accordance with NORAD Agreements first made on May 12, 1958. In the late 1950s, a plan was developed to construct a command and control center in a hardened facility as a Cold War defensive strategy against long-range Soviet bombers, ballistic missiles, and

9393-458: Was hardened to protect it from the effects of a nearby nuclear blast and designed so that the senior military staff could facilitate further military operations. Four years later, construction at Cheyenne Mountain was started to create a similar protection for the NORAD command post. Cheyenne Mountain was excavated under the supervision of the Army Corps of Engineers for the construction of

9494-624: Was issued on November 7, 1957 (BMEWS was "designed to go with the active portion of the WIZARD system ") and on February 4, 1958; the USAF informed Air Defense Command (ADC) that BMEWS was an "all-out program" and the "system has been directed by the President , has the same national priority as the ballistic missile and satellite programs and is being placed on the Department of Defense master urgency list." The subsequent plan by June 1958 for

9595-500: Was re-designated as the J36 branch within the NORAD and USNORTHCOM's Operations Directorates. Since 2002, the complex has been classed as Cheyenne Mountain Air Force Station and has been used in crew qualification training, while the former command function has been redesignated as the "NORAD and USNORTHCOM Alternate Command Center" since 2008 after all the original functions of the complex were removed to Peterson Air Force Base. The complex

9696-603: Was subject to delays and cost overruns. By 1992, the project was estimated to be delayed to 1995 and cost projected to increase from $ 142 million to $ 234 million. By 1992, the U.S. Space Command Space Surveillance Center (SSC) was the data analysis and tracking center for Baker-Nunn camera images and Cheyenne Mountain was connected to the AN/URC-117 Ground Wave Emergency Network (GWEN) communication site in Pueblo, Colorado . By 1995,

9797-408: 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

9898-670: Was the Missile Warning Center Commander and the Chief of the J7 Exercise Branch. In 2003, construction began for a new command center at Cheyenne Mountain to include Ground-Based Midcourse Defense —the "new Missile Correlation Center" (MCC) was to have new consoles, mission system connectivity and communications capabilities. The Missile Correlation Center (MCC) and Space Control Center were in Cheyenne Mountain by March 4, 2005 when Patrick Mullin

9999-536: Was the commander of the MCC, which by 2006 was receiving input from five Joint Tactical Ground Stations. The 2006–8 Cheyenne Mountain Realignment divided MCC operations into NORAD/ NORTHCOM 's Missile and Space Domain at Peterson AFB and STRATCOM's facility in Cheyenne Mountain ("Missile Warning Operations Center" in 2007.) USSTRATCOM announced a 2007 plan to relocate the MWOC from Cheyenne Mountain to Schriever AFB ( cf.

10100-470: 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

10201-489: Was upgraded to the more robust UNIVAC 1100/42 . The 427M system, intended to modernize systems and improve performance, was initially "wholly ineffective" and resulted in several failures of the Worldwide Military Command and Control System (WWMCCS) system. In 1979 and 1980, there were a few instances when false missile warnings were generated by the Cheyenne Mountain complex systems. For instance,
