75-774: Download coordinates as: The following is a list of Nike missile sites operated by the United States Army . This article lists sites in the United States, most responsible to Army Air Defense Command ; however, the Army also deployed Nike missiles to Europe as part of the NATO alliance, with sites being operated by both American and European military forces. U.S. Army Nike sites were also operational in South Korea, Japan and were sold to Taiwan . Leftover traces of

150-721: A Defense Area formed a circle around these cities and bases. There was no fixed number of Nike batteries in a Defense Area and the actual number of batteries varied from a low of two in the Barksdale AFB Defense Area to a high of 22 in the Chicago Defense Area. In the Continental United States the sites were numbered from 01 to 99 starting at the north and increasing clockwise. The numbers had no relation to actual compass headings, but generally Nike sites numbered 01 to 25 were to

225-560: A battery in Leonardo, New Jersey on 22 May 1958, killing six soldiers and four civilians. A memorial can be found at Fort Hancock in the Sandy Hook Unit of Gateway National Recreation Area . Even as Nike Ajax was being tested, work started on Nike-B, later renamed Nike Hercules (MIM-14). It improved speed, range and accuracy, and could intercept ballistic missiles . The Hercules had a range of about 100 miles (160 km),

300-427: A central missile assembly point from which missiles would be taken out to prepared above-ground launch racks ringing the defended area. However, the Army discarded this semimobile concept because the system needed to be ready for instantaneous action to fend off a "surprise attack." Instead, a fixed-site scheme was devised. Due to geographical factors, the placement of Nike batteries differed at each location. Initially,

375-545: A few are intact and preserve the history of the Nike project. General Belgian Nike info: The Nike missile system was operational in the Belgian airforce from 1959 until 1990. It was organized into a Missile Group (the overall staffing); a Support Wing (tech and log support), and 2 (9th and 13th) Missile Wings, each with 4 subordinate units. All Belgian Nike sites were in the 2 ATAF part of then West- Germany . Their defending area

450-492: A few remain intact and preserve the history of the Nike project. There are also a few sites abroad, notably in Germany, Turkey and Greece. Defense areas within the United States were: The Nike boosters were also used as stages in sounding rockets as they became surplus starting in the 1950s in the following versions: Kols%C3%A5s An old farm beneath the mountain has the name Kolsberg . The first element in this name

525-452: A letter, L = launch site, C = IFC (Integrated Fire Control) site. The Formerly Used Defense Sites (FDS) program processed many former sites and then transferred them out of Defense Department control. The Alaska Nike sites were under the control of United States Army Alaska (USARAK), rather than Army Air Defense Command. Air Defense Command / NORAD radar sites at Fire Island AFS (F-1) and King Salmon AFS (F-3) AK were integrated into

600-466: A more appropriate name when the system was put into production. This never came to pass; the original Nike-X concept was replaced by a much more limited defense system known as the Sentinel program that used some of the same equipment. Nike-X was a response to the failure of the earlier Nike Zeus system. Zeus had been designed to face a few dozen Soviet ICBMs in the 1950s, and its design would mean it

675-469: A much longer-ranged, collision-course system named Project Thumper , which eventually delivered the BOMARC missile . Bell Labs' proposal would have to deal with bombers flying at 500 mph (800 km/h) or more, at altitudes of up to 60,000 ft (20,000 m). At these speeds, even a supersonic rocket is no longer fast enough to be simply aimed at the target. The missile must "lead" the target to ensure

750-816: A number of studies carried out between 1965 and 1967 examined a variety of scenarios where a limited number of interceptors might still be militarily useful. Among these, the I-67 concept suggested building a lightweight defense against very limited attacks. When the Chinese exploded their first H-bomb in 1967, I-67 was promoted as a defense against a Chinese attack, and this system became Sentinel in October. Nike-X development, in its original form, ended. The figures do not include approximately 1 billion dollars for research and development, paid to Western Electric. Total cost to Army: 1,545.1 Soviet development of ICBMs decreased

825-533: A single plug on the warhead from the "Safe Plug" to "Surface to Air" or "Surface to Surface" and a range setting in the TRR. The Nike Hercules was deployed starting in June 1958. First deployed to Chicago , 393 Hercules ground systems were manufactured. By 1960 ARADCOM had 88 Hercules batteries and 174 Ajax batteries, defending 23 zones across 30 states. Peak deployment was in 1963 with 134 Hercules batteries not including

900-485: A top speed in excess of 3,000 mph (4,800 km/h) and a maximum altitude of around 150,000 ft (30 km). It had solid fuel boost and sustainer rocket motors. The boost phase was four of the Nike Ajax boosters strapped together. In the 70's some (foreign)users replaced vacuum tube guidance circuits in the missile with more reliable solid-state components but electron tube circuits were still used well into

975-541: A training area for climbers since beginning of the 20th century. Today it is the largest rock climbing area in the Oslo region. The wall Øvre Sydstup on the southern wall has more than 200 climbing routes. The northern hillside of Kolsås has alpine skiing facilities. Kolsåsbanen is part of the subway rail system Oslo T-bane , running from downtown Oslo to Kolsås station , via Gjettum station and Hauger station . The military base Kolsås leir , partly located inside

1050-447: A very fast, short-range missile known as Sprint . Large numbers would be clustered near potential targets, allowing successful interception right up to the last few seconds of the warhead's re-entry. They would operate below the altitude where decoys or explosions had any effect. Nike-X also used a new radar system that could track hundreds of objects at once, allowing salvoes of many Sprints. It would require dozens of missiles to overwhelm

1125-583: Is a missile launch site operated by the US-Army until April 1985. It was part of the Nike-Belt , a defense system which was created to defend Europe against the then newly invented jets. The site fired Nike missiles at potentially incoming jets as part of the Project Nike . The Italian Nike units were initially combined Nike Ajax and Hercules equipped but switched completely over to Nike Hercules in

1200-419: Is sorted by state. The "Missile type" code indicates the numbers and types of missiles and other installation details. For example, "2AK/18L-H" means the site contained two Nike Ajax magazines (A), located above ground (K), with eight launchers (8L) being converted to Nike Hercules (H). Many listings will have "FDS" following either the control site or launch site heading, which means that the site has gone through

1275-565: Is the genitive case of the old male name Kolr , and the last element is berg n 'mountain'. The parish and municipality of Bærum ( Old Norse Bergheimr ) is probably named after this prominent mountain. The last element in the name of the mountain was later changed to ås m 'mountain ridge' to distinguish it from the name of the farm. The area from Kolsås to Dælivannet is a protected landscape area from 1978 (five square kilometers), with four nature reserves : Skotta , Dalbo , Kolsåsstupene and Kolsåstoppen nature reserve . Kolsås has been

1350-507: The Anti-Ballistic Missile Treaty signed during 1972, and further budget reduction, almost all Nike sites in the continental United States were deactivated by April 1974. Some units remained active until the later part of that decade in a coastal air defense role. These trucks and trailers were used with the Nike system. By 1958, the Army deployed nearly 200 Nike Ajax batteries at 40 "Defense Areas" within

1425-581: The Fairbanks area, which included Fort Wainwright and Eielson AFB . Manned by the 2nd Missile Battalion, 562d Air Defense Artillery . The sites around Fairbanks were inactivated in 1970 and 1971. The USAF radar site at Murphy Dome AFS , AK (F-2) was shared with the Army for Nike missile-defense system. The CPS-6B radar was removed in July 1958, FPS-8 removed 4Q 1960 until the Nike sites were inactivated in 1971. Army Air-Defense Command Post (AADCP) LA-45DC

1500-732: The Homestead AFB /Miami Defense Area, those starting with NY were in the New York Defense Area, and so forth. As an example Nike Site SF-88L refers to the launcher area (L) of the battery located in the northwestern part (88) of the San Francisco Defense Area (SF). During the early-to-mid-1960s the Nike Ajax batteries were upgraded to the Hercules system. The new missiles had greater range and destructive power, so about half as many batteries provided

1575-577: The Nike Hercules missile and NASA 's Nike Smoke rocket , used for upper-atmosphere research. Project Nike began during 1944 when the War Department demanded a new air defense system to combat new jet aircraft , as existing gun-based systems proved largely incapable of dealing with the speeds and altitudes at which jet aircraft operated. Two proposals were accepted. Bell Laboratories offered Project Nike while General Electric proposed

1650-628: The Rygge and Gardermoen airbases and the naval base Karljohansvern . Construction of the Nike batteries started in 1959; becoming limited operational in 1960 and fully operational in 1961. Initially operating both Nike Ajax and Hercules but later on only Nike Hercules, the Norwegian Nikes were only conventional armed with the T-45 High Explosive warhead.

1725-496: The "Formerly-Used Defense Site" program and has been transferred from DoD control to another party. With the exception of Alaska, in which sites were given a specific name, Nike missile sites were designated by a coding system of the Defense Area Name abbreviation; a two-digit number representing the degree from north converted to a number between 01 and 99 (North being 01; East being 25; South being 50; West being 75), and

1800-423: The 80's. The electron tube's resistance to EMP effects over earlier non EMP hardened solid state circuits played a major part in the retention of 'obsolete' technology until hardened circuits were developed. The missile also had an optional nuclear warhead to improve the ability to defend against mass formations. The W-31 warhead had four variants offering 2, 10, 20 and 30 kiloton yields. The 20 kt version

1875-650: The AN/GSS-1 Electronic Search Central with the AN/TPS-1D radar) searched for a target to be handed over to the Target Tracking Radar (TTR) for tracking. The Missile Tracking Radar (MTR) tracked the missile by way of a transponder , as the missile's radar signature alone was not sufficient. The MTR also commanded the missile by way of pulse-position modulation , the pulses were received, decoded and then amplified back for

1950-639: The Air Force during 1948. They merged their own long-range research with Project Thumper , while the Army continued to develop Nike. During 1950 the Army formed the Army Anti-Aircraft Command (ARAACOM) to operate batteries of anti-aircraft guns and missiles. ARAACOM was renamed the US Army Air Defense Command (USARADCOM) during 1957. It adopted a simpler acronym, ARADCOM, in 1961. The first successful Nike test

2025-606: The Army National Guard began to replace their guns and adopt the Ajax system. Each launch site had three parts, separated by at least 1,000 yards (914 m). One part (designated C) of about six acres (24,000 m ) contained the IFC (Integrated Fire Control) radar systems to detect incoming targets (acquisition and target tracking) and direct the missiles (missile tracking), along with the computer systems to plot and direct

2100-643: The Army Nike operations. Radars used at Fire Island were CPS-6B, FPS-8, CPS-4, FPS-20A, FPS-6B. Nike missile operations continued there until 1979 when the site was closed. Afterwards, the Army Air Defense Command Post was moved to King Salmon. Radars were FPS-93A and in 1982 the FPS-117 was installed. King Salmon Long Range Radar Site is still in use. Fairbanks Defense Area : Sites were installed to replace Anti-Aircraft guns defending

2175-465: The Launch Area, depending upon site configuration, obstructions, and the availability of land. The Launch Area provided for the maintenance, storage, testing, and firing of the Nike missiles. The selection of this area was primarily influenced by the relatively large amount of land required, its suitability to extensive underground construction, and the need to maintain a clear line-of-sight between

2250-547: The MTR to track. Once the tracking radars were locked the system was able to work automatically following launch, barring any unexpected occurrences. The computer compared the two radars' directions, along with information on the speeds and distances, to calculate the intercept point and steer the missile. The entirety of this system was provided by the Bell System's electronics firm, Western Electric . The Douglas -built missile

2325-497: The US Army Hercules batteries deployed in Germany, Greece, Greenland, Italy, Korea, Okinawa, Taiwan, and Turkey. In 1961, SAC and the U.S. Army began a joint training mission with benefits for both parties. SAC needed fresh (simulated) targets which the cities ringed by Nike/Hercules sites provided, and the Army needed live targets to acquire and track with their radar. SAC had many Radar Bomb Scoring (RBS) sites across

2400-557: The USAF Strategic Air Command , later Military Airlift Command base. The 436th Anti-Aircraft Artillery Battalion was active by 1955. The 436th AAAB was redesignated as an antiaircraft artillery missile battalion on 5 January 1957 and subsequently occupied four Nike Ajax sites, which went to 1st Missile Battalion, 61st Artillery on 1 September 1958. Controlling the SAMs was the 29th Artillery Group (Air Defense). During

2475-662: The United States (including Alaska and Hawaii) in which Project Nike missiles were deployed. Within each Defense Area, a "Ring of Steel" was developed with a series of Nike Integrated Firing and Launch Sites constructed by the Corps of Engineers. The deployment was designed to initially supplement and then replace gun batteries deployed around the nation's major urban areas and vital military installations. The defense areas consisted of major cities and selected United States Air Force Strategic Air Command bases which were deemed vital to national defense. The original basing strategy projected

2550-481: The United States' first operational anti-aircraft missile system, the Nike Ajax , in 1953. A great number of the technologies and rocket systems used for developing the Nike Ajax were re-used for a number of functions, many of which were given the "Nike" name (after Nike , the goddess of victory from Greek mythology ). The missile's first-stage solid rocket booster became the basis for many types of rocket including

2625-598: The aircrews. The results of these bomb runs were used to promote or demote air crews. ECM activity also took place between the bombers and the Nike sites. The performance of the NIKE crews improved remarkably with this "live target" practice. Many Nike Hercules batteries were manned by Army National Guard troops, with a single active Army officer assigned to each battalion to account for the unit's nuclear warheads. The National Guard air defense units shared responsibility for defense of their assigned area with active Army units in

2700-681: The approximately 265 Nike missile bases can still be seen around cities across the United States. As the sites were decommissioned, they were first offered to federal agencies. Many were already on Army National Guard bases who continued to use the property. Others were offered to state and local governments, while others were sold to school districts. The leftovers were offered to private individuals. Many Nike sites are now municipal yards, communications, and FAA facilities, probation camps, and even renovated for use as airsoft gaming and military simulation training complexes. Several were obliterated and turned into parks. Some are now private residences. Only

2775-403: The area, and reported to the active Army chain of command. This is the only known instance of Army National Guard units being equipped with operational nuclear weapons. Development continued, producing Improved Nike Hercules and then Nike Zeus A and B. The Zeus was aimed at intercontinental ballistic missiles (ICBMs). Zeus, with a new 400,000 lbf (1.78 MN) thrust solid-fuel booster,

2850-466: The continental United States until 1974. The Alaskan sites were deactivated in 1978 and Florida sites stood down during the following year. Although the missile left the U.S. inventory, other nations maintained the missiles in their inventories into the early 1990s and sent their soldiers to the United States to conduct live-fire exercises at Fort Bliss, Texas. Leftover traces of the approximately 265 Nike missile bases can still be seen around cities across

2925-478: The country which had very similar acquisition and tracking radar, plus similar computerized plotting boards which were used to record the bomber tracks and bomb release points. Airmen from these sites were assigned TDY to Nike sites across the country to train the Nike crews in RBS procedures. The distances from the simulated bomb landing point and the "target" were recorded on paper, measured, encoded, and transmitted to

3000-596: The country. As the sites were decommissioned they were first offered to federal agencies. Many were already on Army National Guard bases who continued to use the property. Others were offered to state and local governments while others were sold to school districts. The left-overs were offered to private individuals. Thus, many Nike sites are now municipal yards, communications and FAA facilities (the IFC areas), probation camps, and even renovated for use as Airsoft gaming and MilSim training complexes. Several were obliterated and turned into parks. Some are now private residences. Only

3075-427: The intercept. The second part (designated L), around forty acres (160,000 m ), held 1–3 underground missile magazines each serving a group of four launch assemblies and included a safety zone. The site had a crew of 109 officers and men who ran the site continuously. One launcher would be on 15 minutes alert, two on 30 minutes and one on two hour alert. The third part was the administrative area (designated A), which

3150-557: The international political situation in the world. The logistics train was airlifting by US CH-47's within 6 hrs after receipt of a coded message. This event actually took place in October 1962 during the Cuban missile crisis when NATO came on full alert. On Okinawa, the 30th ADA Brigade was on Okinawa. On Reversion Day, May 15, 1972, all Nike Hercules missile sites were handed over to the JASDF. Battery B,8th Battalion,3rd Air Defense Brigade

3225-468: The larger size of the Nike Hercules, an underground magazine's capacity was reduced to eight missiles. Thus, storage racks, launcher rails, and elevators underwent modification to accept the larger missiles. Two additional features that readily distinguished newly converted sites were the double fence and the kennels housing dogs that patrolled the perimeter between the two fences. The Nike Hercules

3300-511: The late 1960s and early 1970s, the Travis battalion assumed responsibility for the remaining active batteries guarding the entire San Francisco region. Inactivated by 1974. Nike (rocket)#Project legacy Project Nike (Greek: Νίκη , "Victory") was a U.S. Army project, proposed in May 1945 by Bell Laboratories , to develop a line-of-sight anti-aircraft missile system. The project delivered

3375-507: The mid-1970s. Each site with a US Custodial Team had an on-site load of 10 nuclear warheads ready to be launched at very short notice. The sites were using mixed warheads; meaning always 2 sections nuclear-capable ( W31 selectable 20 or 2 kiloton yield) and 1 section only conventional (T-45 High Explosive) armed. Another 60 spare W31's had been kept in permanent storage at grid 45°28'46"N 11°35'57"E Longare . These were supposed to be airlifted to certain Nike sites in case of deterioration of

3450-465: The missile could be pushed manually along a railing to a launcher placed parallel to the elevator. Typically, four launchers sat atop the magazine. Near the launchers, a trailer housed the launch control officer and the controls he operated to launch missiles. In addition to the launch control trailer, the launch area contained a generator building with three diesel generators, frequency converters, and missile assembly and maintenance structures. Because of

3525-519: The missile to help ensure a lethal hit. The missile's limited range was seen by critics as a serious flaw, because it often meant that the missile had to be situated very close to the area it was protecting. Consolidated Western Steel produced the launcher loaders. Fruehauf Trailer Corporation produced the trailers. After disputes between the Army and the Air Force (see the Key West Agreement ), all longer-range systems were assigned to

3600-482: The missiles in the Launch Area and the missile-tracking-radar in the Battery Control Area. The first Nike sites featured above-ground launchers. This quickly changed as land restrictions forced the Army to construct space-saving underground magazines. Capable of hosting 12 Nike Ajax missiles, each magazine had an elevator that lifted the missile to the surface in a horizontal position. Once above ground,

3675-433: The northeast and east, those numbered 26 to 50 were to the southeast and south, those numbered 51 to 75 were to the southwest and west, and those numbered 76 to 99 were to the northwest and north. The Defense Areas in the Continental United States were identified by a one- or two-letter code which were related to the city name. Thus those Nike sites starting with C were in the Chicago Defense Area, those starting with HM were in

3750-407: The planners chose fixed sites well away from the defended area and the Corps of Engineers Real Estate Offices began seeking tracts of land in rural areas. However, Army planners determined that close-in perimeter sites would provide enhanced firepower. Staggering sites between outskirt and close-in locations to urban areas gave defenders a greater defense-in-depth capability. Each Nike missile battery

3825-571: The project was canceled in favor of the Thor based Program 437 system during 1966. In the end, neither development would enter service. However, the Nike Zeus system did demonstrate a hit-to-kill capability against ballistic missiles during the early 1960s. See National Missile Defense and anti-ballistic missile (ABM) systems. Nike Hercules was included in SALT I discussions as an ABM. Following

3900-601: The remaining missile batteries. When the Army abandoned the launch area of SF-88 at Fort Barry in 1974, the National Park Service assumed custody of the site, incorporating it into the Golden Gate National Recreation Area . Through the efforts of various volunteer groups, as of 1995, this is the only Nike site in the country that has been preserved and is open for public viewing. Army Air-Defense Command Post (AADCP) SF-90DC

3975-610: The same defensive capability. Regular Army batteries were either upgraded to the Hercules system or decommissioned. Army National Guard units continued to use the Ajax system until 1964, when they too upgraded to Hercules. Eventually, the Regular Army units were replaced by the National Guard as a cost-saving measure, since the Guard units could return to their homes when off duty. A Nike Ajax missile accidentally exploded at

4050-621: The system. Nike-X considered retaining the longer range Zeus missile, and later developed an extended range version known as Zeus EX . It played a secondary role in the Nike-X system, intended primarily for use in areas outside the Sprint protected regions. Nike-X required at least one interceptor missile to attack each incoming warhead. As the USSR's missile fleet grew, the cost of implementing Nike-X began to grow as well. Looking for lower-cost options,

4125-560: The target is hit before the missile depletes its fuel. This means that the missile and target cannot be tracked by a single radar, increasing the complexity of the system. By this point, the US had considerable experience with lead-calculating analog computers , starting with the British Kerrison Predictor and a series of increasingly capable U.S. designs. For Nike, three radars were used. The acquisition radar (such as

4200-420: The value of the Nike (aircraft) air defense system. Beginning around 1965, the number of Nike batteries was reduced. Thule air defense was reduced during 1965 and SAC air base defense during 1966, reducing the number of batteries to 112. Budgetary cuts reduced that number to 87 in 1968, and 82 in 1969. Some small-scale work to use Nike Zeus as an anti-satellite weapon (ASAT) was carried out from 1962 until

4275-497: The warhead damage. Nike Hercules batteries at SAC bases and in Hawaii were installed in an outdoor configuration. In Alaska, a unique above-ground shelter configuration was provided for batteries guarding Anchorage and Fairbanks. Local Corps of Engineer Districts supervised the conversion of Nike Ajax batteries and the construction of new Nike Hercules batteries. Nike missiles remained deployed around strategically important areas within

4350-406: Was a two-stage missile using a solid fuel booster stage and a liquid fueled ( IRFNA / UDMH ) second stage . The missile could reach a maximum speed of 1,000 mph (1,600 km/h), an altitude of 70,000 ft (21 km) and had a range of 25 miles (40 km). The missile contained an unusual three part payload , with explosive fragmentation charges at three points down the length of

4425-1405: Was at the Vestvolden , a fortification at grid 55°41'23"N 12°26'11"E connected with the Karup Air Force Headquarters 94th ADA Group, headquartered in Kaiserslautern for most of the Nike-Hercules period had four battalions as follows, with locations: 2/1 ADA headquartered at Wiesbaden Air Base - A Battery: Wackernheim - B Battery: Dexheim - C Battery: Quirnheim - D Battery: Dichtelbach 5/6 ADA headquartered in Neubruecke - A Battery: Schoenborn - B Battery: Wueschheim - C Battery: Baumholder - D Battery: Hontheim 2/56 ADA headquartered in Pirmasens - A Battery: Geinsheim - B Battery: Landau - C Battery: Salzwoog - D Battery: Oberauerbach 3/71 ADA headquartered in Ludwigsburg - A Battery: Dallau - B Battery: Grosssachsenheim - C Battery: Hardheim - D Battery: Pforzheim - In Pforzheim (Hagenschieß/Wurmberg), in Baden-Württemberg there

4500-582: Was deployed first at Fort Meade, Maryland during December 1953. A further 240 launch sites were built up to 1962. They replaced 896 radar-guided anti-aircraft guns , operated by the National Guard or Army to protect certain key sites. This left a handful of 75 mm Skysweeper emplacements as the only anti-aircraft artillery remaining in use by the US. By 1957 the Regular Army AAA units had been replaced by missile battalions. During 1958

4575-481: Was designed to defend Minuteman ICBMs, and which was also based on the Nike-X system. It became operational in 1975, but was shut down after just three months. Nike-X was a proposed US Army anti-ballistic missile (ABM) system designed to protect major cities in the United States from attacks by the Soviet Union 's ICBM fleet. The name referred to its experimental basis, it was intended to be replaced by

#1732787166276

4650-432: Was designed to use existing Nike Ajax facilities. With the greater range of the Nike Hercules allowing for wider area coverage, numerous Nike Ajax batteries were permanently deactivated. In addition, sites located further away from target areas were desirable due to the nuclear warheads carried by the missile. Unlike the older Ajax sites, these batteries were placed in locations that optimized the missiles' range and minimized

4725-416: Was divided into two basic parcels: the Battery Control Area and the Launch Area. The Battery Control Area contained the radar and computer equipment. Housing and administration buildings, including the mess hall, barracks, and recreation facilities, were sometimes located in a third parcel of land. More likely, however, the housing and administration buildings were located at either the Battery Control Area or

4800-409: Was during November 1951, intercepting a drone B-17 Flying Fortress . The first type, Nike Ajax (MIM-3), were deployed starting in 1953. The Army initially ordered 1,000 missiles and 60 sets of equipment. They were placed to protect strategic and tactical sites within the US. As a last-line of defense from air attack, they were positioned to protect cities as well as military installations. The missile

4875-576: Was established at Mill Valley AFS , CA in 1960 for Nike missile command-and-control functions. The site was equipped with the AN/GSG-5(V) BIRDIE solid-state computer system. SF-90DC was integrated with the USAF Air Defense Command / NORAD Semi Automatic Ground Environment (SAGE) air defense radar network as Site P-38 / Z-38 The AADCP was inactivated in mid-1971. Travis AFB Defense Area (T) : Established to defend

4950-490: Was established at San Pedro Hill AFS , CA in 1960 for Nike missile command-and-control functions. The site was initially an AN/FSG-l Missile-Master Radar Direction Center. It was later equipped with the AN/TSQ-51 "Missile Mentor" solid-state computer system. LA-45DC was integrated with the USAF Air Defense Command / NORAD Semi Automatic Ground Environment (SAGE) air defense radar network as Site RP-39 / Z-39 The AADCP

5025-529: Was first test launched during August 1959 and demonstrated a top speed of 8,000 mph (12,875 km/h). The Nike Zeus system utilized the ground-based Zeus Acquisition Radar (ZAR), a significant improvement over the Nike Hercules HIPAR guidance system. Shaped like a pyramid, the ZAR featured a Luneburg lens receiver aerial weighing about 1,000 tons. The first successful intercept of an ICBM by Zeus

5100-532: Was in 1962, at Kwajalein in the Marshall Islands . Despite its technological advancements, the Department of Defense terminated Zeus development in 1963. The Zeus system, which cost an estimated $ 15 billion , still suffered from several technical flaws that were believed to be uneconomical to overcome. Still, the Army continued to develop an anti-ICBM weapon system referred to as "Nike-X" – that

5175-423: Was inactivated 1 Sep 1974 along with the remaining Nike Hercules sites. San Francisco Defense Area (SF) : San Francisco was defended by 12 Nike sites: SF-08, SF-09, SF-25, SF-31, SF-37, SF-51, SF-59, SF-87, SF-88, SF-89, SF-91 and SF-93. Its defenders included both Regular Army and National Guard units. Sites SF-87 and SF-93 were deactivated in 1971. Three years later, the U.S. Army Air Defense Command deactivated

5250-626: Was largely based on the technological advances of the Zeus system. Nike-X featured phased-array radars, computer advances, and a missile tolerant of skin temperatures three times those of the Zeus. In September 1967, the Department of Defense announced the deployment of the LIM-49A Spartan missile system, its major elements drawn from Nike X development. In March 1969. the Army started the anti-ballistic missile Safeguard Program , which

5325-496: Was largely useless by mid-1960s when it would be facing hundreds. It was calculated that a salvo of only four ICBMs would have a 90% chance of hitting the Zeus base, as their radars could only track a few warheads at the same time. Worse, the attacker could use radar reflectors or high-altitude nuclear explosions to obscure the warheads until they were too close to attack, making a single warhead attack highly likely to succeed. Nike-X addressed these concerns by basing its defense on

5400-511: Was located on the Chinen peninsula in southern part of the island. The U.S. reverted the islands to Japan on May 15, 1972, setting back a Ryūkyū independence movement that had emerged. A Battery was located on Isikawa Dake, the narrow waist of the island. There was also a battery at Naha. These were covering the Norwegian capital, the former Kolsås HQ Allied Forces Northern Europe (AFNORTH),

5475-516: Was the industrial Ruhr area. As Greenland is Danish and that country refused to host foreign military and nuclear weapons, a bilateral agreement was signed allowing access for all US forces and weaponry in Greenland. This way all Thule batteries could yet be nuclear armed. Hq Nike Group and staffing was located at the Avedøre camp , at grid 55°37'59"N 12°26'55"E. Nike Group Operations Control

5550-459: Was used in the Hercules system. At sites in the United States the missile almost exclusively carried a nuclear warhead. Sites in foreign nations typically had a mix of high explosive and nuclear warheads. The fire control of the Nike system was also improved with the Hercules and included a surface-to-surface mode which was successfully tested in Alaska. The mode change was accomplished by changing

5625-601: Was usually co-located with the IFC and contained the battery headquarters, barracks, mess, recreation hall, and motor pool. The actual configuration of the Nike sites differed depending on geography. Whenever possible the sites were placed on existing military bases or National Guard armories; otherwise land had to be purchased. The Nike batteries were organized in Defense Areas and placed around population centers and strategic locations such as long-range bomber bases, nuclear plants, and (later) ICBM sites. The Nike sites in
