The Martin AN/FSG-1 Antiaircraft Defense System, better known as Missile Master, was an electronic fire distribution center for United States Army surface-to-air missiles. [5] It aimed to computerize Cold War air defense (AD) command posts [4] from manual plotting board operations [6] to automated command and control. [7] [8]
The 10 C3 systems used radar netting ("electronic umbrella") [9] at Missile Master military installations for coordinating ground-controlled interception by Nike and MIM-23 Hawk missiles. The vacuum tube fire control logic reduced the time to designate the appropriate missile battery to launch if an enemy target had intruded into a defense area where an AN/FSG-1 system was deployed.
The AN/FSG-1 was an outgrowth of the July 1945 Signal Corps' Project 414A for an electronic Air Defense Fire Distribution System (ADFDS), [10] a 1950 prototype computer and console system, [11] and the 1954 experimental forerunner/"test system" [3] [12] : 55 (AN/GSG-2) installed at Fort George G. Meade. [11] The 1st AN/FSG-1 was contracted in August 1955, [13] the program had been publicly announced by August 1956, [3] Missile Master sites had been selected by June 1957, [14] and the "operational" [4] AN/FSG-1 at the Fort Meade radar station was "put into action" on December 5, 1957. [15] A 13-minute AN/FSG-1 military film (MF 11-8923) was produced in 1958, [7] and Congressional funding for additional sites was initiated in 1959 after the "Missile Master Plan" resolved the Army Project Nike and USAF CIM-10 Bomarc plans for SAM air defense. [16]
During the October 1959-July 1960 study regarding the system's algorithm for Automatic Target and Battery Evaluation (ATABE), [17] the "first production model AN/FSG-1" was dedicated in January 1960 at Fort Lawton Air Force Station (AFS), Washington. [18] : 313 Following installation, a checkout period, and AN/FSG-1 acceptance; a dedication ceremony was often held and open to media (e.g., May 1960 acceptance at Highlands AADS, New Jersey, [13] with June 5 dedication). [19] The "SAGE/Missile Master test program" conducted large-scale field testing of the AN/FSG-1 "mathematical model" using actual radar tracks of SAC and ADC aircraft sorties[ clarification needed ] into the defense areas [17] (SAC-simulated bomb runs were planned after September 22, 1960). [18] : 314 The last (10th) AN/FSG-1 was dedicated in December 1960 at Fort MacArthur, California.

With the availability of solid-state direction center (DC) equipment such as the Martin AN/GSG-6 BIRDIE deployed in 1961, the United States Department of Defense approved in December 1963 the replacement of the AN/FSG-1. [18] : 317 Six were replaced with Hughes AN/TSQ-51 Air Defense Command and Coordination Systems [34] with the last replacement on February 8, 1967, at Oakdale AFS, Pennsylvania. [18] : 317, 320 Ft Lawton, [35] Fort Heath MA, [34] and Lockport AFS NY [36] were replaced with BIRDIEs [9] while instead of replacement, the AN/FSG-1 at Pedricktown Army Air Defense Base was removed after its defense area was incorporated[ when? ] into the combined New York-Philadelphia Defense Area controlled by Highlands AADS [37] —which later switched to a BIRDIE by July 1, 1972 [34] : C-23 (conversely, Ft Heath & Lockport subsequently switched from BIRDIE to AN/TSQ-51). [34]
The "semiautomatic" [4] : 17 AN/FSG-1 automatically plotted target tracks, evaluated missile sites for use against a target, and automated the communication with batteries. [38] The automation reduced delay "by four or five times" over the previous command post method with manual plotting, [6] review of hardcopy performance charts to estimate an intercept point, and telephone voice commands. [19] Operators at the AADCP reviewed the 19 in (48 cm) [39] orange interactive plan position indicator CRTs which displayed the AN/FSG-1 radar network's data, e.g., "14 pieces of information…height, level, priority, direction…", [40] etc. in the tiered Antiaircraft Operations Center (AAOC). The "Blue Room" [19] was recessed in a pit with a stage, [41] blue walls, blue overhead fluorescent illumination, and more than 12 blue consoles. In the rear of the AAOC was the highest "third row [with] a "friendly protector" console, three tactical monitor consoles, and a tactical director's console. The defense commander's room…at the top rear" had a window for viewing into the AAOC. [12] The AAOC crew was typically 22 soldiers and 5 company grade officers. [42]
Via an automated data link (ADL) of digital information, [4] the AN/FSG-1 communicated the identification friend or foe status from the AADCP to remote fire units where a "foe" symbol was placed "around[ specify ] each radar return on the scope". [43] The AN/FSG-1 assigned a Nike fire unit to a target using the same ATABE "programmed selection logic" as the USAF SAGE system, and the algorithm could be tested using a simulator (a "20-target raid…with maneuvering targets, takes approximately 1 1/4 minutes.") [17] When the AN/FSG-1 had automatically assigned a battery to a foe, a technician used the "entry stick" to alert the battery to "prepare to engage" (e.g., lock the Target Tracking Radar on the target). [31] The director's console was subsequently used to manually input the attack command, and the AN/FSG-1 transmitted [44] a change[ specify ] to the foe symbol at the designated fire unit [43] where the Battery Control Officer reacted to the symbol and issued the firing order to a ready[ specify ] missile. [5] The AN/FSG-1 also provided[ clarification needed ] a communication function previously performed[ clarification needed ] by the Interim Battery Data Link (IBDL) system which had transmitted the "missile away" notification from the firing battery to other sites, allowing "battery commanders to see which targets were being engaged by other batteries".

Fort George G. Meade is a United States Army installation located in Maryland, that includes the Defense Information School, the Defense Media Activity, the United States Army Field Band, and the headquarters of United States Cyber Command, the National Security Agency, the Defense Courier Service, Defense Information Systems Agency headquarters, and the U.S. Navy's Cryptologic Warfare Group Six. It is named for George G. Meade, a Union general from the U.S. Civil War, who served as commander of the Army of the Potomac. The fort's smaller census-designated place includes support facilities such as schools, housing, and the offices of the Military Intelligence Civilian Excepted Career Program (MICECP).
Fort MacArthur is a former United States Army installation in San Pedro, Los Angeles, California. A small section remains in military use by the United States Air Force as a housing and administrative annex of Los Angeles Air Force Base. The fort is named after Lieutenant General Arthur MacArthur. His son, Douglas MacArthur, would later command American forces in the Pacific during World War II.
Ground Equipment Facility J-33 is a Federal Aviation Administration (FAA) radar station of the Joint Surveillance System's Western Air Defense Sector (WADS) with an Air Route Surveillance Radar (ARSR-4). The facility was previously a USAF general surveillance radar station during the Cold War.
Highlands Air Force Station was a military installation in Middletown Township near the borough of Highlands, New Jersey. The station provided ground-controlled interception radar coverage as part of the Lashup Radar Network and the Semi-Automatic Ground Environment network, as well as providing radar coverage for the Highlands Army Air Defense Site. The site's 240 acres (97 ha) is now the Rocky Point section in Hartshorne Woods Park of the Monmouth County Parks System.
Fort Heath was a US seacoast military installation for defense of the Boston and Winthrop Harbors with an early 20th-century Coast Artillery fort, a 1930s USCG radio station, prewar naval research facilities, World War II batteries, and a Cold War radar station. The fort was part of the Harbor Defenses of Boston and was garrisoned by the United States Army Coast Artillery Corps. The fort's military structures have been replaced by a residential complex, including the luxurious Forth Heath Apartments, and recreation facilities of Small Park, which has both a commemorative wall and an historical marker for Fort Heath.
The SAGE radar stations of Air Defense Command were the military installations operated by USAF squadrons using the first automated air defense environment and networked by the SAGE System, a computer network. Most of the radar stations used the Burroughs AN/FST-2 Coordinate Data Transmitting Set (CDTS) to automate the operator environment and provide radar tracks to sector command posts at SAGE Direction Centers (DCs), e.g., the Malmstrom Z-124 radar station was co-located with DC-20. The sector/division radar stations were networked by DCs and Manual Control Centers to provide command, control, and coordination for ground-controlled interception of enemy aircraft by interceptors such as the F-106 developed to work with the SAGE System.
Fort Lawton Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located on Fort Lawton in the Magnolia neighborhood of northwest Seattle, Washington. The Air Force inactivated its unit in 1963; while the site remained under Army control until 1974. Today the Federal Aviation Administration (FAA) operates the site as part of the Joint Surveillance System (JSS).
The Fort Meade radar station was an air defence radar installation used by the Army and USAF. The site operated c. 1950 until 1979 and had a Project Nike command post and radar network.
The Hughes AN/TSQ-51 Air Defense Command and Coordination System was a transportable electronic fire distribution center for automated command and control of remote Nike missile launch batteries. The radar netting system replace the vacuum tube AN/FSG-1 in 6 United States Missile Master bunkers after the upgrade was approved by the United States Department of Defense in 1963; and additional deployments were at Homestead-Miami, Florida, and Providence, Rhode Island, to replace Battery Integration and Radar DIsplay Equipment (BIRDIE) systems; as well as at San Francisco. As with the AN/FSG-1, the AN/TSQ-51 could provide fire control for 24 Nike batteries, but the smaller AN/TSQ-51 could be fielded in 2 trailers.
The Sievers Sandberg Reserve Center is a U.S. Army Reserve training installation in New Jersey. It occupies 39 acres (16 ha).
Missile Master was a US Army surface-to-air missile control complex/facility. It controlled Project Nike missiles. Virtually all Missile Masters had a bunker housing the Martin AN/FSG-1 Antiaircraft Defense System, as well as additional structures for "an AN/FPS-33 defense acquisition radar (DAR) or similar radar, two height-finder radars," and identification friend or foe secondary radar. The radars, along with Automated Data Links (ADL) from remote Nike firing units, provided data into the AN/FSG-1 tracking subsystem with the DAR providing surveillance coverage to about 200 mi (320 km).
The Martin AN/GSG-5 Battery Integration and Radar DIsplay Equipment (BIRDIE) was a transportable electronic fire distribution center for automated command and control of remote surface-to-air missile launch batteries. The solid state radar netting system replaced the vacuum tube AN/FSG-1 at 3 United States Missile Master bunkers and BIRDIEs were deployed at over 25 US locations including Homestead-Miami, Florida; Providence, Rhode Island; and San Francisco. The AN/GSG-5 with 3 consoles was a direction center for up to 16 Nike missile batteries, but a smaller variant with only 1 console and without computer and storage equipment could control only 2 batteries and was the 1st BIRDIE deployed. Several BIRDIE systems were replaced by Hughes AN/TSQ-51 Air Defense Command and Coordination Systems, and the last AADCP with an AN/GSG-5 was at Ft Lawton on July 1, 1973.
The Highlands Army Air Defense Site (HAADS) was a United States Army air defence site in Middletown Township, New Jersey.
The Western Electric System 1393 Radar Course Directing Central (RCDC) was a Cold War complex of radar/computer systems within the overall Improved Nike Hercules Air Defense Guided Missile System. The RCDC was installed at the "battery control areas" of ~5 hectares each which was for commanding a nearby missile Launching Area (LA), firing a missile from the LA, and guiding a launched missile to a burst point near an enemy aircraft.
The Raytheon AN/MSQ-18 Battalion Missile Operations System was a Project Nike command, control, and coordination system for "each associated missile battery" to control a Nike missile as directed from a Raytheon AN/MSQ-28 at the Army Air Defense Command Post. Raytheon Company constructed the AN/MSQ-18 as 2 separate subsystems:
The Martin AN/TSQ-8 Coordinate Data Set was a Project Nike CCCS system for converting data between Army Air Defense Command Posts (AADCP) and Integrated Fire Control sites for missile Launch Areas. The AN/TSQ-8 in the Firing Unit Integration Facility (FUIF) was first installed for each Launch Area controlled from a Martin AN/FSG-1 Antiaircraft Defense System and then later for other Nike CCCS. The system included a "data converter, range computer, summing amplifier, status relay panel, status control panel, problem unit, [and] power control panel".
A command, control, and coordination system (CCCS) was a Cold War computer system for United States command posts to use a single location to coordinate multiple units' ground-controlled interception and may refer to:
The Arlington Heights Army Air Defense Site was a Project Nike Missile Master site near Chicago, Illinois. It operated from 1960 until 1968.
The Fort Heath radar station was a USAF radar site and US Army Missile Master installation of the joint-use site system (JUSS) for North American Air Defense at a former coastal defense site. The Cold War radar station had 2 USAF AN/FPS-6B height finding radars, 2 Army AN/FPS-6A height finders, an FAA ARSR-1 radar emplaced 1958-9, and an Army nuclear bunker. Arctic Towers were the pedestals for the FPS antennas and radomes, while the Air Route Surveillance Radar was on a 50-foot extension temperate tower adjacent to the Federal Aviation Administration building.
NORAD Control Centers (NCCs) were Cold War "joint direction centers" for command, control, and coordination of ground-controlled interception by both USAF Air Defense Command (ADC) and Army Air Defense Command (ARADCOM). The Joint Manual Steering Group was "formed by the Army and Air Force in July 1957 to support…collocation" of USAF Air Defense Direction Centers and Army Air Defense Command Posts, which began after a January 28, 1958, ADC/ARADCOM meeting with NORAD to "collocate the Fairchild-Geiger facilities" Army contracts for 5 NCCs had been let by August 17, 1958, after 1956 DoD approval for collocation of interim "pre-SAGE semiautomatic intercept systems" and radar squadrons at 10 planned Army Missile Master AADCPs
