CHRONOLOGY OF THE DEVELOPMENT
OF BALLISTIC MISSILE DEFENSE

1955

Mar (U) Western Electric Company (WECo) and Bell Telephone Laboratories (BTL) began an 18-month study of a "new forward looking ground-to-air guided-missile system capable of effectively engaging the target threats within the Continental United States (CONUS) during the period 1960 - 1970."

[NIKE-ZEUS Guided Missile System", Volume I, System Study Report prepared by BTL and Douglas Aircraft Company on behalf of Western Electric Co., Inc., 1 Mar 57, Page vii, Foreword.]

Primary emphasis in the NIKE-II study was to be on defense against the intercontinental ballistic missile (ICBM). The 18-month study was under Contract DA-30-069-ORD-1082, with funding of $1.65 M.

15 Nov (U) An Air Force contract for a 12-month anti-ICBM weapon study was awarded to WECo. Two other defense contractors, Boeing and Lockheed, were selected for the Air Force competitive study.

2 Dec (U) A full status report of the Nike II system study was presented to Army Ordnance at Redstone Arsenal, AL. A common data gathering system was proposed using a defensive missile with interchangeable noses, one for intercepting air-breathing targets and the other for engaging ballistic targets.

1956

21 Mar (U) Limited exploratory development and experimental studies of component hardware for the NIKE-II System were provided in a further extension of the existing Contract DA-30-069-0RD-1082. $1.8 M was added to expedite exploratory hardware work.

Jun (U) Chief of Ordnance determined that tests of NIKE-II should be planned at White Sands Missile Range (WSMR) with the possible exception that radars might be placed on Ascension Island to acquire and track targets of opportunity fired from Cape Canaveral.

1 Oct (U) The NIKE-II feasibility study was completed, and the results were presented to the Army General Staff by WECo. The study defined the threat expected to confront the air defenses of the U.S. between 1960 - 1970 and described the proposed weapon system for confronting it. The study includes a discussion of the guidance problem, the equipment that is recommended for its solution, a summary of exploratory development work performed, and a proposed schedule for a development program.

(U) The study concluded that it is feasible to provide an anti-ICBM defense with the NIKE-II System. If development of the system were funded at maximum rate, the first operational capability could be obtained in late calendar year 1962 under a normal production program.

2 Oct (U) The Special Assistant for Guided Missiles to the Secretary of Defense informed the Secretaries of the Army and the Air Force that in the antimissile field, the Air Force would have responsibility for developing the early warning system and the Army would have responsibility for the active defense system. The assignment to the Army was justified on the grounds that major targets were already defended by NIKE sites; NIKE-II appeared to be the only project beyond the study stage capable of accomplishing the mission, and there was a basic similarity between the anti-ICBM problem and the anti-missile-missile for field army use.

25 Oct (U) The Department of Defense Anti-ICBM Committee was notified of the following possible schedules for NIKE-II.

Operational Availability Date

Maximum Rate Funding

Budget Limited Funding

1. Early anti-ICBM capability (75-mile range, 130,000 ft altitude).

4th Qtr CY 62

3rd Qtr CY 65

2. Full high-altitude anti-ICBM capability (75-mile range, 500,000 ft altitude).

4th Qtr CY 63

2nd Qtr CY 67

3. Extended range antiaircraft (manned and unmanned) capability.)

4th Qtr CY 64

1st Qtr CY 69

Nov (U) The Army Chief of Research and Development formally directed the Chief of Ordnance to initiate phased development of the NIKE-II System. Funds were made available in the amount of nine million dollars. The phased program had the following three objectives:

1. To develop an early anti-ICBM capability to 130,000 feet altitude and 75 nautical miles range.

2. To develop a full anti-ICBM capability to 500,000 feet altitude and 75 nautical miles range.

3. To develop an extended range capability against aircraft, manned or unmanned to 200 nautical miles range.

15 Nov (U) Per DA Cir 700-22, the following popular names were assignedto the NIKE family of missiles:

NIKE-AJAX – NIKE-I
NIKE-HERCULES – NIKE-B
NIKE-ZEUS - NIKE-II

1 Dec (U) Contract DA-30-069-ORD-1082 was supplemented to include active development of the NIKE-II System by WECo. This marks the beginning of actual development work.

1957

Jan (U) U. S. Continental Army Command (CONARC) was presented a draft of military characteristics of the NIKE-II System. CONARC recommended to the Joint Chiefs of Staff (JCS) that NIKE-II be implemented in two phases: Early Capability Anti-missile-missile and the Antiaircraft Missile.

Feb (U) The Army awarded Western Electric/Bell Telephone Laboratories prime contractor system responsibility for development of an anti-ICBM defense system and changed its name from NIKE-II to NIKE-ZEUS. The research and development effort was under Army Ordnance Contract DA-30-069-0RD-1955, and was administered through the New York Ordnance District. With the growing concern for the ICBM threat, BTL effort would now concentrate solely on the ICBM defensive missile, terminating work on defense against air-breathing targets. '

1 Mar (U) The final written report on the NIKE-II (NIKE-ZEUS) study was published: "System Study, NIKE-ZEUS Guided Missile System, Bell Laboratories Report, Vol I Requirements, and Vol II Appendices."

Apr (U) Secretary of Defense (Charles E. Wilson) detailed areas of responsibility for the major services regarding missile and system development. He approved recommendations that the Air Force develop the early warning system and communications; that the Army carry out research and development on Local Acquisition Radar (LAR), Target Track Radar (TTR), and the missile for ICBM defense; and that a joint Army-Air Force Committee be established (Skifter Committee) to monitor missile development.

Sep (U) A joint Atomic Energy Commission - Department of Defense study concluded that it was feasible to develop a warhead for NIKE-Zeus which would be capable of destroying an ICBM warhead and that such a warhead could become available by 1961.

Oct (U) Cost and schedule data were developed by army studies, to indicate an operational, on-site defense of Continental United States (CONUS). Assuming an accelerated program wherein production of tactical NIKE-ZEUS equipment would be undertaken concurrently with manufacture and test of the prototype, and assuming availability of funds by 1 Jan 58, the following schedule was provided:


Estimated Cumulative Cost

Early Capability


3 batteries* by end-CY 61
30 batteries by end-CY 62

$2.0 billion

Full Capability


100 batteries by end-CY 65

$4.0 billion

Extended Range Capability


100 batteries by mid-CY 66

$6.0 billion



A battery comprised all the elements required for carrying out the engagement of an assigned target: radars for tracking and discrimination, defensive missiles, and related computer equipment. The organizational concept envisioned at this time (1958) for deployment of the NIKE-ZEUS System consisted of two major elements beside the weapons batteries: the Local Defense Center (LDC), consisting of the Local Acquisition Radar (LAR) and tactical control equipment for the one to five batteries associated with the LDC; the Forward Acquisition Radar (to be deployed forward of the defended area in the direction of possible ICBM attack) which was to acquire target data to be transmitted to the LDC's.

3 Oct (U) The Redstone Anti-Missile Missile Systems Office (RAMMSO) was established, per General Order No. 55, U. S. Army Ordnance Corps, Redstone Arsenal, to direct and control the NIKE-ZEUS Project. RAMMSO was under the command of the Acting Deputy Commander for Anti-Missile Missile Systems.

17 Oct (C) The NIKE-ZEUS program was reoriented to provide a system capability according to the following phased programs: Phase I -development of the local control system and an anti-missile missile limited to approximately 100,000 feet altitude and approximately 70 nautical miles range. Phase II - development of an anti-missile missile with jet-head, thereby extending capabilities to 500,000 feet altitude. Phase III - development of an anti-missile missile with a fully active seeker, thereby extending range capabilities against aerodynamically supported aircraft to approximately 200 nautical miles.

1958

Jan (U) A study was completed on sites considered for jet-head tests: (RSA Report No. AM-ZB-1-58) "Determination of the Test Locations for Certain NIKE-ZEUS Tests", dated 29 Jan 58. Recommendation from study was that jet-head development tests be performed at Point Mugu.

(U) By National Security Council action, the highest national priority ("S - Priority") was established for the development of NIKE-ZEUS.

16 Jan (U) The Secretary of Defense (Neil McElroy) directed that development effort of a missile system against the ICBM be under the direction of the Advanced Research Projects Agency (ARPA). Until ARPA could be established, the Secretary directed maximum coordination of the effort between the Army and the Air Force. The Army was directed to "continue its development effort in the NIKE-ZEUS program as a matter of urgency, concentrating on system development that will demonstrate the feasibility of achieving an effective, active anti-ICBM system in an electronic counter measure and decoy environment."

[Memorandum for the Secretary of the Army from the Secretary of Defense, subj: Program for Defense Against the Intercontinental Ballistic Missile, dtd 16 Jan 58.]

The work was to be limited to the missile and launch system, and the acquisition, tracking and computer components required for an integrated missile system. In a separate memorandum, the Secretary of Defense directed the Air Force to continue that portion of its NIKE-ZEUS program pertaining to early warning and acquisition and tracking radars, discontinuing its effort on the missile system proper.

28 Jan (U) The Office of the Chief of Research and Development, forwarded to the Director of Guided Missiles, Army, the following recommendations with regard to attaining an early defense against ballistic missiles:

1. Drop from further consideration for accelerated development and deployment for defense, all active ballistic missile defense systems except NIKE-ZEUS and the land-based TALOS.

b. As first priority, fund the NIKE-ZEUS program.

[On 30 Sep 58, representatives of WECo and the New York Ordnance District (NYOD) signed Supplement No. 9 to Contract DA-069-ORD-1955, covering the research and development effort for the NIKE-ZEUS program from 1 Oct 58 to 30 Sep 59. The contract amounted to $135 million and was the largest single contract ever negotiated by the NYOD. A production planning contract with WECo was initiated in FY 59 in the amount of $19. 9 million.]

30 Jan (U) Chief of Ordnance requested that Redstone Arsenal organize reconnaissance for facilities for downrange Atlantic Missile Range testing.

Mar (U) Funds as specified in studies of AM-1-58 were not available by 1 Jan 58. New guidelines were established for revising AM-1-58, the most significant being the limitation of funds to be made available for this program during FY 59. The lack of FY 58 industrial funds plus the limitation of funds during FY 59. resulted in a slippage of the planned operational date.

1 Apr (U) The Army Rocket and Guided Missile Agency (ARGMA) was organized as a subordinate element of the U. S. Army Ordnance Missile Command (USAOMC) at Redstone Arsenal, Alabama, by USAOMC General Orders No. 6.

Apr (U) Ascension, Antigua, and Barbuda Islands were reconnoitered as possible downrange sites for NIKE-ZEUS testing. Detailed results of the reconnaissance were included in ARGMA Report Nr. AM-ZB-2-58, "Test Site Reconnaissance of Antigua, Ascension, and Barbuda Islands for Project NIKE-ZEUS", dated 28 May 58.

14 Apr (U) Redstone Anti-Missile-Missile Systems Office (RAMMSO) was abolished, per General Order No. 5, U. S. Army Ordnance Missile Command. The mission of RAMMSO was assumed by various segments of ARGMA.

1 Jun (U) ARGMA was established as a Class II activity under jurisdiction of the Chief of Ordnance, by DA General Order No. 22.

Nov (U) State Department informed DOD that the NIKE-ZEUS Project would not obtain permission from United Kingdom for use of Barbuda as a ZEUS test site. The Chief of Ordnance directed that a new test site for downrange tests be selected and new test plans be prepared. Though it was originally planned to conduct the ZEUS downrange program in the Atlantic Missile Range, the directive did not restrict the test site selection to existing or proposed impact areas in either the Atlantic or Pacific Missile Range (the Kwajalein -Johnston Island complex was subsequently chosen).

Nov (U) Award of contract and start of construction of NIKE- ZEUS experimental facilities at WSMR. (This was the first specific ZEUS structure, but work was actually started on roads, utilities, etc., as early as Feb 58.)

Dec (U) ARGMA received from Office, Chief of Ordnance, a teletype which stated that the FY 60 PEMA "shopping list" did not mention the NIKE-ZEUS program. If no FY 60 industrial funds were provided, the planned initial operational capability date would be delayed to Jun 64. This teletype also stated that the Department of Defense had not approved an operational date for the NIKE-ZEUS.

1959

2 Jan (U) U. S. Army Air Defense Command was assigned responsibility for preliminary selection of sites for the NIKE-ZEUS System.

12 Feb (U) The Ballistic Missile Committee of the Department of Defense approved a test plan for conducting NIKE-ZEUS tests in the Kwajalein-Johnston Island complex utilizing intermediate range ballistic missile (IRBM) targets. Steps were immediately begun to prepare agreements with the Department of the Navy and the Department of the Air Force to establish responsibilities and methods of operation. This plan was also approved by the Dir-ectorof Guided Missiles on 2 Mar 59.

1 Mar (U) The Army Ballistic Missile Agency (ABMA) was delegated responsibility for development of ballistic targets for the NIKE-ZEUS test program. ABMA developed the criteria for the facilities at Johnston Island.

Apr (U) Design release of the first 15 research and development missiles was completed and six were fabricated. Missiles were early capability type without jet reaction nose.

May (U) DOD approved a 40 x 40 mile extension to WSMR for use in connection with the NIKE-ZEUS test program.

30 Jun (U) Award of a contract for the first package of construction at Kwajalein Island was opened by the Honolulu District Engineers. Included in this bid was one Target Track Radar (TTR) building, Acquisition Radar Receiver, Receiver Antenna, and transmitter buildings.

Jul (U) A new missile configuration was approved. The missile airframe was simplified and strengthened by removing the large wings from the sustainer section (small wings later had to be added for stability). This design increased range and maneuverability and simplified handling, maintenance, and launching. Initial flights of this design were to begin in mid-1960.

Jul (U) Bids for facilities at Ascension Island, test site for the TTR, were opened. Facilities covered include BOQ, generator sets, water tanks, utilities, and TTR building.

(U) DOD directed a dual development approach of a warhead for the NIKE-ZEUS System.

Aug (U) ARG MA published a NIKE-ZEUS test plan. Test sites and their utilization were as follows:

WSMR for the development portion of the radar tests and for missile tests in the 80 - 120 nautical mile category.

Point Mugu, California (Pacific Missile Range) for initial testing in the 560 nautical mile category.

Kwajalein-Johnston Island Complex for performance of the downrange test program, and for final radar performance and system tests in the 250 and 560 nautical mile category.

Ascension Island was chosen as the site for TTR tests because it afforded an opportunity to test radar effectiveness against ICBM targets fired from Cape Canaveral.

26 Aug (U) The first NIKE-ZEUS missile (Nr. 101) was fired at WSMR. Overall results of the test were partially successful. The missile broke up shortly before sustainer-booster separation. This missile, and the other two rounds fired in 1959, were designed for uncontrolled flights, constructed with fixed-fins and a dummy nose instead of the thrust vectoring nose.

22 Sep (U) A Memorandum of Understanding was executed between the Army and the Navy to provide peacetime coordination of the NIKE-ZEUS test program in the Kwajalein-Johnston Island complex.

Oct (U) The WSMR Acquisition Radar Receiver building and the Acquisition Radar Transmitter building were completed, with equipment ready for installation.

14 Oct (U) The second NIKE-ZEUS missile (Nr. 102) was fired at WSMR. Lift-off, boost phase, separation, sustainer ignition and sustainer operation were successful. Missile failsafe and loss of telemetry occurred at 35.3 seconds; insufficient altitude was attained to acquire warhead component data, but other test objectives were met successfully.

Nov (U) The Deputy Secretary of Defense approved use of 30 JUPITERS for IRBM-type targets to be fired from Johnston Island in the NIKE-ZEUS test program. A contract was let by ABMA for fabrication of 15 of these targets. (This decision was later reversed; see page 12, entry for 25 - 26 May 60. )

4 Dec (U) A revised launching and handling concept was approved which provided for subsurface launching of the NIKE-ZEUS missiles. A subsurface cell was approved for installation at WSMR for checking the design prior to acceptance for the Kwaja-lein Test Site. Contract award for the construction of this cell was 22 Dec 59.

16 Dec (U) The third fixed-fin, winged NIKE-ZEUS missile (Nr. 104) was fired at WSMR. Complete success was not achieved in that the sustainer did not ignite.

1960

3 Feb (U) The fourth NIKE-ZEUS fixed-fin, winged missile (Nr. 105) was fired at WSMR. The firing was a complete success, with all test objectives met.

28 Apr (U) This was the initial test of a NIKE-ZEUS missile launched from an underground prototype cell at WSMR. Objectives of obtaining design criteria for the underground type cell and investigating the effect of exhaust gases on missile performance were achieved.

May (U) Design was completed for all facilities at WSMR, Point Mugu, and Ascension Island except for certain minor changes.

25-26 May (U) An ad hoc panel was appointed by the Special Assistant to the President for Science and Technology to resolve the controversy over which target missiles should be used to test the NIKE-ZEUS System. The Army proposed use of JUPITER intermediate range ballistic missile (IRBM) targets launched from Johnston Island for intercept by NIKE-ZEUS missiles launched from Kwajalein Atoll. The Director of Defense Research & Engineering (DDR&E) advocated the substitution of ATLAS intercontinental ballistic missiles (ICBMs) to be launched from Vandenberg Air Force Base (VAFB). After two days of hearings, the panel ruled in favor of the latter.

29 Jun (U) A memorandum from the Secretary of Defense to the Secretaries of the Army, Navy, and Air Force directed that all NIKE-ZEUS ICBM targets would be delivered by ATLAS missiles launched from VAFB. Plans for development of launch facilities at Johnston Island, and the production of all JUPITER missiles for use in NIKE-ZEUS testing were cancelled.

20 Jul (U) The Army Rocket and Guided Missile Agency (ARGMA) received the first increment ($18 million) of the $25 million previously authorized for prove-out of manufacturing techniques for certain critical ZEUS System components.

10 Aug (U) The ninth ZEUS missile (20009) was successfully fired at WSMR. This was the first firing of the advanced design ("wingless") missile.

Oct (U) The NIKE-ZEUS Field Office was formally established at WECo, Burlington, N. C. This location was to provide the government a rapid response to needs of contract or program changes.

28 Oct (U) Memorandum of Agreement between the Army-Air Force on the ICBM target program was signed.

Nov (U) Installation of the Missile Track Radar (MTR) at WSMR was completed.

21 Nov (U) The NIKE-ZEUS-Ad Hoc Advisory Committee, chaired by Mr. Richard S. Morse, transmitted to the Chief of Staff the report of the Committee relating to early production and deployment of the NIKE-ZEUS System. Recommendations were:

1. That a program for the production of NIKE-ZEUS batteries at the rate of four per year be immediately initiated.

2. That the units produced be deployed in the defense of the North American Continent in consonance with antimissile defense plans of the North American Air Defense Command (NORAD).

3. That the present NIKE-ZEUS research and development program be continued with the primary objectives of determining the system effectiveness against various types of threats and of improving this effectiveness consistent with the state of the art.

Dec (U) Installation of the Target Track Radar (TTR) on Ascension Island was completed and power turned on.

1 Dec (U) The 12th NIKE-ZEUS missile (20013) was successfully launched at WSMR from open pit launcher 207 at a quadrant elevation of 70 degrees, marking the first guided missile firing. Thrust separation and simultaneous control were for the first time successfully employed in a missile of this type.

4 Dec (U) Secretary of the Army recommended to the Secretary of Defense that:

1. An interim program for production and deployment of NIKE-ZEUS at the rate of four batteries, two defense centers, and 200 missiles per year be initiated without delay.

2. FY61 funds in the amount of $73.3 million be provided to permit initiation of a production contract by 31 Mar 6l.

3. Units produced be deployed as recommended by Commander-in-Chief, NORAD.

1961

Jan (U) The Army Rocket and Guided Missile Agency (ARGMA) submitted the "NIKE-ZEUS Defense Production Plan" to the Chief of Ordnance. The plan provided for the production and deployment, over a period of eight years, of 29 defense centers, 70 batteries and supporting equipment, and 3,610 missiles. Total cost was estimated at $8 billion. The Secretary of the Army approved the plan and it was forwarded to the Secretary of Defense for approval.

25 Jan (U) The NIKE-ZEUS Test Unit, U. S. Army Air Defense Command (ARADCOM), was organized at the Army Air Defense Center, Ft. Bliss, Texas, with the mission of assisting the Army Air Defense Board 1n conducting and evaluating a "valid user test of the NIKE-ZEUS System."

Mar (U) Two Target-lntercept Computers, one at WSMR and one at Point Mugu, were successfully operated for over 40 million transistor hours and nine million transistor hours respectively.

29 Mar (U) The first attempt of the Target Track Radar (TTR) on Ascension Island to track an ICBM fired from Cape Canaveral failed because the TTR computer did not properly translate trajectory data.

28 May (U) The TTR on Ascension Island successfully tracked an ATLAS missile fired from Cape Canaveral.

6 May (U) The TTRs at BTL and Ascension Island tracked the ECHO I satellite to a distance of 2,000 miles.

25 May (S) After several partial failures of the advanced missile design, the firing of ZEUS missile ZW16 (20021) at WSMR was a complete success. The missile remained on trajectory for the 88-seconds flight duration, in a severe thermodynamic environment, and proved that the heating problem could be overcome.

Jun (U) Authorization to proceed with the design of a prototype model of a phased array radar, based on an earlier BTL study, was added to the ZEUS prime contract with WECo (BTL retained responsibility for supervision of the design). Sylvania was selected as the major subcontractor for detailed design of the prototype model and fabrication of the model to be installed at WSMR. Sperry Rand Univac was subcontractor for the digital computer as well as programming for the prototype radar.

(U) The prototype ZEUS Multifunction Array Radar (ZMAR) (later referred to as MAR-I) was an exploratory system which would perform the functions of acquisition, discrimination and tracking of ICBMs by electronic scanning. The phased array would have no mechanical moving parts and no necessity for a rotating antenna. Four installations at 90 degree intervals would be required to cover 360 degrees in azimuth.

Jul (U) The ZEUS Acquisition Radar (ZAR) at WSMR operated as a system for the first time. A track on a target aircraft was successfully initiated by ZAR data processing equipment.

(U) Successful tracking of a NIKE-ZEUS missile by the Missile Track Radar (MTR) was maintained during firing from the underground launch cell at WSMR.

Aug (U) The ZEUS missile research and development firing schedule was revised with the principal change being a reduction of 28 missile firings at Point Mugu and a corresponding increase in tests at WSMR. The shift in location stemmed from a decision to test fire more ZEUS missiles without separation of the 2nd and 3rd stages. This mode would lessen range safety problems associated .with higher altitude flights and permit firings at White Sands where missile parts could be recovered for analysis and study.

Sep (U) The first successful jet-head, single blast tube, elbow and nozzle test firing was conducted at Sacramento, California.

9 Sep (U) NIKE-ZEUS missile ZM-1 (20025) was launched at Point Mugu, California. This was the first NIKE-ZEUS missile tested at Point Mugu. Test objectives were partially achieved.

22 Sep (U) The Secretary of Defense approved the first two phases of a three phase plan for production and deployment of NIKE-ZEUS defense of twelve metropolitan areas. This decision was to be reversed in January 1962, when the Secretary of Defense informed Congress that only those funds required to keep the NIKE-ZEUS development program at "top priority level" would be spent in FY 63.

15 Nov (U) NIKE-ZEUS missile ZW-28 (20030) was launched at WSMR against a HIGHBALL. II missile, the first firing of a ZEUS missile against a real target. Test objectives were partially achieved.

22 Nov (U) The Ascension Island TTR, participating in an ATLAS test, acquired the target at 680 kilometers and tracked continuously for 96 seconds until splash.

14 Dec (U) Three ZEUS firings were successfully conducted at different locations.

1. NIKE-ZEUS ZM-6 (20043) was successfully test fired at Point Mugu, in the longest and highest test flight made to date.

2. At WSMR, the ZEUS ZW-34 (20041) successfully acquired, tracked and intercepted a high altitude, maneuvering supersonic NIKE-HERCULES missile. This was the first intercept of a HERCULES guided missile, and also the first successful integrated system test.

3. NIKE-ZEUS ZK-1 (20047) was test fired from Kwajalein against a space point, the first firing from this test facility.

Dec (U) Unofficial reports circulated in the press implied that President John F. Kennedy and Secretary of Defense McNamara had decided to ask for ZEUS production funds in the new military budget. In presenting his FY 63 budget to Congress in Jan 62, however, President Kennedy indicated his decision to delay the production decision pending final ZEUS firings against ATLAS targets later in 1962.

1962

24 Jan (U) The Kwajalein ZEUS Acquisition Radar (ZAR) received its first signal returns from an intercontinental ballistic missile (ICBM), the initial test of the ZAR against a real target.

17 Feb (U) The ZAR at Kwajalein successfully acquired and transmitted the position of an ATLAS missile to the Target Track Radar (TTR). This marked the first transfer of an ICBM target from the ZAR to the TTR.

Mar (U) The data processing equipment at Kwajalein was integrated into the ZAR subsystem. Tracks were initiated on an ATLAS ICBM fired from VAFB and target position data were successfully transferred to the battery, the first time that a track has been initiated on an ICBM by the Acquisition Radar data processing equipment.

30 Mar (U) A feasibility study was completed on a fast-reaction, surface-to-air missile which by its rapid acceleration, would maximize the time available to a defense for discriminating between warheads and possible decoys. This missile, designated SPRINT, would become a subsystem of the NIKE-X System.

18 Apr (U) The ZAR at Kwajalein participated in a satellite-tracking exercise. Track was initiated and maintained on two objects designated as SPUTNIK 12. On 19 Apr 62, the ZAR again tracked the SPUTNIK 12 booster and successfully transferred the target to the TTR.

27 Apr (U) The Secretary of Defense placed a requirement on the NIKE-ZEUS program to provide the capability, by 1 May 63, for a satellite interception demonstration at Kwajalein. The project was assigned the code name MUDFLAP.

Jun (U) The Deputy Commanding General, Guided Missiles, of the Army Ordnance Missile Command (AOMC), approved a staff study utilizing WECo/BTL as prime contractor for the ZEUS and Hardsite Defense Systems with the government directing the selection of major subcontractors.

[The Hardsite Defense System was defined at this time as, "a hardened system consisting of a Multiple Array Radar Subsystem, a Data Processing and Control Subsystem, a SPRINT Missile Subsystem, and associated support equipment." Experimental models of the Multiple Array Radar (MAR) (or ZMAR, as it was known until Jan 63) were to supply the basic technology for a multi-function radar to replace the current ZEUS radars.]

A pre-award survey of possible subcontractors would begin 11 Jun 62, for the development and production of the SPRINT missile.

Jun (U) The NIKE-ZEUS research and development contract was modified to provide FY 62 authority to develop a satellite intercept system.

26 Jun (U) The entire NIKE-ZEUS system was installed at KMR, consisting of a hemispheric Acquisition Radar (ZAR); two Target Track Radars (TTRs); one Discrimination Radar (DR); three Missile Track Radars (MTRs); battery control equipment and target interceptor computer; four ZEUS launch cells. The first test of the entire system with an interceptor ICBM fired from Vandenburg AFB was attempted on this date. Tracking of the RV was lost and the test was unsuccessful.

Jul (U) WECo was informed that the NIKE-ZEUS production planning contract (ORD-2612) would be terminated when the funds already in the contract were used up.

19 Jul (U) NIKE-ZEUS ZK-7 (20071) made the first successful interception of an ICBM ballistic target nose cone, flown at true ICBM range, speed and trajectory, over Kwajalein. The miss-distance was estimated to be within the lethal blast radius of the ZEUS warhead. Target was boosted into trajectory by an ATLAS missile launched from VAFB.

NIKE-ZEUS & NIKE-X Development

(U) The United States research on ballistic missile defense began in 1945 when the Army initiated, through the Bell Telephone Laboratories, a feasibility study for developing an anti-aircraft missile. The NIKE-AJAX was the first defensive missile to reach full development, and its performance was impressive enough to warrant its deployment, in the early nineteen-fifties, around U. S. cities and air bases as a bomber defense. The 2nd generation NIKE was the nuclear-tipped HERCULES, emerging as an operational missile in 1958. A total of 3,000 HERCULES missiles were produced and deployed against bomber attacks.

(U) While HERCULES was being developed, a missile specifically to defend against other missiles was under study, and in 1955 the Army initiated a contract for the investigation of the first true antimissile missile. This led to the develop-ment and successful testing of the NIKE-ZEUS system. The famous NIKE-ZEUS trial over Kwajalein on 19 July 1962 became a milestone in the evaluation of our strategic defense forces, for it demonstrated what the skeptics had doubted: that "a bullet can hit a bullet." An incoming ICBM, fired from Vandenberg Air. Force Base, was actually intercepted and theoretically destroyed by a ZEUS missile.

(U) In early 1963 , DoD directed work on an advanced system which would include more versatile and higher capacity radars and computers, and an interceptor missile fast enough to be launched after an enemy object re-entered the atmosphere. The advanced system was designated NIKE-X, and its development was conducted on the highest priority.

(U) Under the NIKE-X project multifunctional radars were developed which could search and track enemy missiles, and guide and track defensively launched missiles. These radars incorporated the phased-array technique, which could generate many beams and steer them electronically across the sky in a matter of microseconds, thus permitting complete coverage of the radar horizon. (U) An interceptor missile capable of accelerating to a terminal velocity of many thousands of feet per second in a few seconds was another vital development under NIKE-X. The SPRINT missile can be withheld from fire until after enemy objects re-enter the atmosphere; the radar can then accomplish discrimination, filtering out the decoys to designate the real warhead before the SPRINT is launched to intercept it.

(U) Production and deployment of the NIKE-X System had been considered at the highest governmental levels for several years prior to the production decision of September 1967. While the major NIKE-X effort was devoted to development, some deployment planning effort had been undertaken, and in 1965, two major contributions to deployment preparation were completed. The first of these was a maintenance study which provided a basis for manning and logistical support of a deployed NIKE-X System. The second was the organizational plan approved by the Department of the Army (DA) on 5 Jun 65, visualizing a NIKE-X System Manager at DA level. This System Manager would execute a decision to deploy the NIKE-X Weapon System, using the existing Army Staff to the maximum extent to assist him. He would be supported in the field by the major Army commands and agencies and by a sizable NIKE-X field organization which would be under hi s direct command.

(U) Upon approval of the organizational plan, the Chief of Staff of the Army directed that a cadre be set up to plan implementation of the concept. An implementation plan was completed in March 1966. The time was now appropriate to designate a System Manager for NIKE-X, and in October 1966, the Chief of Research and Development, Lieutenant General A. W. Betts, was appointed to act as NIKE-X System Manager in addition to his other duties. At the same time, the NIKE-X Project Office and the NIKE-X Engineering/Service Test Office of the Army Materiel Command (AMC) were placed under the operational control of the System Manager to assist him in the field. The NIKE-X System Office was organized and located in the Washington ;area to,assist the System Manager in carrying out his mission.

(U) One of the first actions of the System Manager was to prepare and issue Letters of Instruction to each of the Army major commands and agencies which was to have a NIKE-X role .and mission. A second action of major importance by the NIKE-X System Manager was to establish representative deployment models, thereby providing a common basis for planning by all agencies. The first accepted deployment model was termed "DEMOD 1-67", and it defined a mix of weapons for a specified amount of money keyed to a "thin" defense. On 5 Jul 67, Secretary of Defense Robert McNamara was briefed on this deployment model, as well as on alternatives which would provide defense against the more advanced Soviet threat and against the fractional orbital bonbardment system (FOBS) threat. (U) Secretary McNamara asked for a 30-day study of the evolving Chinese Communist threat and of a deployment based on modular growth to counter it. A committee was established by the Director of Defense Research and Engineering (known as the Montgomery Committee) which held its first meeting on 11 Jul 67. The committee presented a generally favorable report on 15 Aug, indicating that the NIKE-X DEMOD 1-67 constituted an adequate base for proceeding.

(U) In a speech on 18 Sep 67 before the United Press International Editors and Publishers in San Francisco, the Secretary of Defense announced the decision to proceed with production and deployment of an antiballistic missile system.

[This speech is reproduced in full as Document 1, Supporting Documents.]

The defensive system as outlined by Secretary McNamara was a relatively modest "thin" shield, estimated to cost $5 billion, and principally to defend against the growing threat from the Chinese People's Republic.

(U) Secretary McNamara explained his opposition to deploying a large scale, or "thick" ACM system, not primarily because of the estimated $40 billion price tag, but because he felt that it was not possible to build an impenetrable shield which would guarantee protection of our population against a Soviet attack. Should we attempt to build such a system - at whatever price - a corresponding Soviet reaction would be virtually certain, and the U. S. would, in the long run, gain no significant improvement in security. The system approved by Secretary McNamara was therefore not designed to protect against a Soviet attack on U. S. cities, but had other objectives. One was in relation to the emerging nuclear capability of Communist China. Other objectives were to provide protection against an accidental intercontinental ballistic missile launch by any nuclear-capable foreign power, and to preserve an option for protection of certain of our MINUTEMAN sites against attack from any enemy nation, to insure survival of a portion of our offensive retaliatory capability.

(U) The deployed system was to consist of the SPRINT and SPARTAN interceptor missiles, whose development had begun under the NIKE-ZEUS and NIKE-X projects; the perimeter acquisition radar (PAR) and the missile site radar (MSR) utilizing technology from previous phased array radar programs; and a data processing system to fulfill the command and control function. The name "SENTINEL" was given to the system in November 1967, in General Orders 48. These orders designated the U. S. Army Air Defense Command (ARADCOM), with headquarters in Colorado Springs, Colo., the ultimate user of the system. The CG, SENSCOM, as Deputy SENTINEL System Manager, would have command "over tactical SENTINEL sites during the activation phase, until acceptance of the operational site by the CG, ARADCOM."

SUMMARY OF THE SENTINEL PROGRAM FY 68

(U) With the announcement of plans to deploy the antiballistic missile system, the Army moved rapidly to put the SENTINEL System into being. The NIKE-X Project was discontinued and the SENTINEL System established by general orders issued on 15 Nov 67. The U. S. Army Engineer Division, Huntsville was established in October 1967, and the SENTINEL Logistics Command on 15 Apr 68. Both agencies will be collocated with SENSCOM when the new SENSCOM Headquarters Building is completed early in 1969. The Army Air Defense Command rapidly expanded its site selection activities. Four SENTINEL contact teams, each headed by the commanding general of the region, went into action, presenting briefings to the public and to local officials in each potential site area. Under the SENTINEL System Command, the pace of the pre-production program quickened, as contractor effort stepped up on computer programing, engineering design, and complete documentation of the system - the groundwork for actual deployment. A measured buildup of personnel brought the SENSCOM nearer to its total approved strength of nearly 1,000 civilians and 125 military. Progress in missile and radar development and testing, in training plans, and in site activation planning is briefly summarized below.

(U) Based on cost, schedules, and current technology, it was decided not to build an R&D prototype perimeter acquisition radar (PAR). Phasedarray technology had been developed under such previous radar programs as the Multifunction Array Radar I and II, and the Air Force AN/FDS-85. Configuration of the PAR was extensively reviewed in FY 69, with a decision in favor of the single face design, capable of expansion to two or three faces. Traveling wave tubes would be used to energize the antenna elements. A common aperture would both transmit and receive. With the PAR requirements and configuration defined, Phase I was completed; Phase II, the design and manufacture of the first PAR at a site near Boston, began late in FY 68.

(U) An R&D version of the missile site radar (MSR) has been installed in the Meck Island control building. "Power-on" of the MECK MSR, demonstrated 18 May 68, was a key event of FY 68. Integration of the MSR with its associated data processor began in late May. The MECK MSR will be used to track targets and guide missiles in tests of the SENTINEL System, scheduled to start in November 1969.

(U) Missile development continued, with the first successful test firings of the SPARTAN, launched from Kwajalein Missile Range, occurring in March and May of this year. The SPRINT flight testing program began the fiscal year with a successful flight in August 1967, in which the missile for the first time executed a second stage maneuver on command. Of the twelve FY 68 test firings, six were termed fully successful, achieving all objectives. A SPRINT investigating committee, chaired by Dr. H. W. Augustadt of BTL, studied the SPRINT program and recommended certain design changes to increase the reliability and structural integrity of the missile. Modifications to extend the range/flight time of the SPRINT were developed in FY 68, and it was planned to test the extended range SPRINT in July 1969.

(U) It had been determined under the NIKE-X System that commercially available computers were not adequate to the system's requirements for speed, realtime capability and reliability. Bell Telephone Laboratories, with the help of several subcontractors, is developing data processing hardware specifically for the SENTINEL System, termed Central Logic and Control (CLC). Two sites are in use for the checkout of CLC hardware, and for software development: the Data Processing Laboratory at Whippany, N. J. and the Missile Site Data Processor at Meek Island.

(U) Software development presented major problems in this FY. The concurrent evolution of hardware and software posed scheduling problems, and the development of an operating system (the NIKE-X Operating System or NEXOS) presented time-consuming and severe difficulties. Some slippages in tactical software development will result. However, the checkout of NEXOS is now nearing completion. The Whippany Data Processing Laboratory was reconfigured in June 1968 to operate as a split system, doubling the time available for software development, and a split system operation for the MECK data processing system was planned for early 1969.

(U) A Central Training Facility (CTF), located at Ft. Bliss, Tex., will be the site for all resident training for the SENTINEL System. Engineer/service test (EST) courses, conducted at White Sands Missile Range by the contractor, were initiated in this fiscal year for the major SENTINEL subsystems (with the exception of the PAR). These courses are designed to qualify personnel to participate in the testing of R&D equipment and provide early technical training. The first combined SPARTAN/SPRINT EST course started in August 1967, and the first MSR course in March 1968.

(U) A Training Devices Working Group was established in December 1967. A training contract was awarded in May 1968 for assistance in developing a task and skill analysis, and for an independent review and evaluation of training plans.

(U) Production of hardware for the SENTINEL System will be initially accomplished through continuation of (ILLEGIBLE) and development contract structure inaugurated under the NIKE-X System. A pre-production contract with the Western Electric Co., awarded 1 Apr 67 for a 6-month period, was extended to 1 Apr 68. On this date, the initial SENTINEL production contract, in the amount of $85,480,628, was awarded. The award will be shared by nine firms including the Western Electric Co., which received $28,000,000.

(U) Ten geographic areas were announced in November 1967 by the Department of Defense as possible site locations for the SENTINEL System. In May 1968, three additional locations were identified. Selection of the potential locations was based mainly tactical and technical considerations, to fulfill the SENTINEL objective of area defense of the entire United States, and to protect the option for point defense of United States strategic forces.

(U) Community relations functions, public meetings and briefings accompanied the site selection and validation efforts. Some opposition has developed locally to installation of a SENTINEL site in a particular area, mainly on the grounds that the SENTINEL installation would adversely affect surrounding communities.

(J) The first site, and the first PAR installation, will be in the Boston area. Initial criteria for the PAR building was approved, and a PAR design contract awarded for the Boston and Detroit PARs, in June 1968. Also in June a contract was awarded for design of the power plants to supply the PARs. Criteria for the MSR building was released in January 1968, and a design and engineering contract awarded. It was planned to begin advanced construction at the PAR site in the Boston area in October 1968, providing the PAR design is sufficiently advanced, and the real estate acquisition completed at this time.

(U) Manpower strength in the SENTINEL System Command at the end of the fiscal year was 823: 719 civilians and 104 military. At the beginning of FY 68, comparable figures for the NIKE-X Project Office were 398 civilians and 49 military. The total approved funding program was $577,745,000 of which $569,735,000 was obligated.

"SUMMARY OF SENTINEL/SAFEGUARD PROGRAM PROGRESS, FY69"

FY 69 was a year of change for the SENTINEL System, with a new designation to "SAFEGUARD System", revised deployment objectives, and reduced deployment plans.

Opposition to the SENTINEL System, and particularly to specific site deployment locations, was at a mounting tempo through 1968 and 1969. Ten potential site areas had been publicly announced by DoD in November 1967, three more in May 1968, and two more on 13 Nov 68. These 15 sites (in addition to two additional areas, Washington, D.C., and Fairbanks, Alaska, which were never publicly announced were to be located in the following general areas:

Boston Massachusetts
Chicago, Illinois
Seattle, Washington
San Francisco, California
Whiteman Air Force Base, Missouri
Detroit, Michigan
Grand Forks Air Force Base, North Dakota
Albany, Georgia
Malmstrom Air Force Base, Montana
Dallas, Texas
Warren Air Force Base, Wyoming
Salt Lake City, Utah
Los Angeles, California
New York City, New York
Oahu, Hawaii

Briefing teams, composed variously of personnel from the Air Defense Command, the SENTINEL System Command, the SENTINEL System Office and Corps of Engineers, visited many of the above locations. They conducted public meetings and disseminated general information to local and state officials and press media of SAFEGUARD objectives and deployment plans. Increasingly the teams met with hostile questioning, challenges to debate the ABM issue, doubt (ILLEGIBLE) and effectiveness of the SENTINEL System, and criticism of planned site locations.

Scientific and environmental groups joined with peace organizations and citizens' groups to voice their adverse reaction to deployment of an ABM system. The objections generally expressed were that such a system would be obsolete when deployed, would be ineffective, would only serve to accelerate the arms race, or would endanger and despoil a particular locale.

Resistance to the SENTINEL System reached peak momentum by early 1969, with especially adverse reaction in Boston, Seattle, and Chicago. Between 10 and 26 Feb 69, over 2300 pieces of correspondence were received in Washington relative to the proposed SENTINEL System, and the ratio of opposition to support was about 20 to 1.

President Nixon, following his inauguration in January 1969, announced that a thorough review of the SENTINEL System would be made. Pending the outcome, all SENTINEL site activities, construction, and site surveys were halted. On 14 March 69, President Nixon announced his decision to reorient the ABM system, calling the new approach "a safeguard program." The principal defense objective changed from an area defense of the United States to a defense of the U. S. offensive forces. Three objectives were defined:

Safeguard the U. S. deterrent system.
Safeguard against an ICBM attack by the People's Republic of China.
Safeguard against an accidental attack from any source, of less than massive magnitude.

Deployment of the revised ABM system would be at twelve potential sites with the important proviso that the program would be reviewed annually, and site deployments authorized incrementally in consonance with the National defense posture and the international strategic situation. Five of the 12 sites were unchanged from the SENTINEL Program: Grand Forks, Malmstrom, Whiteman and Warren Air Force Bases, and Washington, D.C. The other 7 sites were identified regionally as follows:

Upper Northwest
Central California
Southern California
Central Texas
Michigan/Ohio
Florida, Georgia
Southern New England

The first phase of the revised deployment would authorize only Grand Forks and Malmstrom as ABM sites. The name change to "SAFEGUARD" became official on 25 Mar 69 and all organizational elements were accordingly redesignated. Contracts were modified where necessary, and a new SAFEGUARD System Deployment Description was issued in April 1969.

Site selection activities were in process at many cf the proposed SENTINEL sites when the directive to halt all site acquisition/construction came in late January 1969. Actual construction, however, had commenced only in the Boston area, which was to be the first SENTINEL site. A pre-construction and excavation contract had been awarded in September 1968 for the PAR building and power plant and another contract for power generating equipment. A construction contract had been awarded, on 22 Jan 69, to Morrison-Knudsen Company. The contractor had mobilized and accomplished a small amount of drilling and excavation work when the termination order was issued on 6 Feb 69.

Development of SAFEGUARD weapon systems continued in FY 69 and was not significantly affected by the changed deployment objectives. However, considerable revision of tactical operational planning, the command and control of the deployed system, and software weapons (ILLEGIBLE) from the new ballistic missile defense rationale.

The performance/design specifications for SPARTAN and SPRINT were accepted, with minor changes, by the SENTINEL Configuration Control Board on 20 Sept 68. Development testing of the SPARTAN, at Kwajalein Missile Range (KMR), and the SPRINT, at White Sands Missile Range (WSMR) continued. Fifteen SPARTAN and 42 SPRINT development flights were planned, with the objective of verifying the performance and integrity of missile components, and the ability of the complete missile to function in a tactical weapons system. Following developmental testing, the SPARTAN and SPRINT missiles will be fired from Meck Island in integrated system tests with the Missile Site Radar (MSR) and the missile site data processor (MSDP). The Meek Test Program is scheduled to commence in April 1970. Target requirements for the program have been finalized, using surplus Minuteman and Polaris missiles supplied by the Air Force and Navy for high performance targets. Modifications of nine Intercontinental Ballistic Missiles (ICBM) and 5 Intermediate Range Ballistics Missiles (IRBM) were completed in this fiscal year.

Extensive modifications to KMR facilities to support the Meck Test Program were nearing completion in FY 69. Two SPARTAN launch cells (numbers 21 and 22) were under construction and scheduled for completion this year. The Meck Island Control Building, housing the MSR and missile site data processor, and the test tower for the MSR were completed. The SPRINT complex at Meck Island, consisting of four launch stations, a vertical missile assembly building, and missile holding bay, has been constructed.

Seven SPARTAN missiles were fired in FY 69, with a record of four successful and two partially successful missions, and one failure. Modified Zeus launch facilities at Kwajalein Island, and the Zeus Early Missile Track Radar were used for these missions. The first assembly of the SPARTAN warhead section was completed 12 Dec 68 at Sierra Army Depot, using the tactical ballistic case, and a dynamic warhead model furnished by the Atomic Energy Commission. SPARTAN warhead section tests flights were scheduled to commence in July 1969.

Eleven SPRINT flights were conducted in FY 69, with nine successful, two partially successful and one failing to achieve any objectives. The Meck Test Program will include testing of SPRINT missiles in the remote launch mode. Six tests (five with actual targets) were planned, in which SPRINT will be launched from an adjacent island but acquired and tracked by the MSR located on Meck Island. Remote launches will be conducted from Illeginni, if land lease negotiations with the Marshallese for that island are successful. A secondary site, Gagan Island, where land use rights are already authorized, will be used if Illeginni is unavailable.

Two R&D configurations of the SAFEGUARD data processing hardware, known as "Central Logic and Control" (CLC) were in operation in FY 69, one at the SAFEGUARD Data Processing Laboratory (SDPL) , Whippany, NJ, and the other at the Meck MSR. These are CLC1 design; a tactical design designated CLC2 was planned for installation at the sites and at BTL's Tactical Software Control Site. The SDPL became operational early in FY 69 as a split data processing system, permitting dual, separate software development on each system. Split system operation of the MSDP at Meck Island was also begun in the second quarter, FY 69.

Meck-0 software, a set of real time processes to check out the MSR, MSDP and their interfaces prior to system testing, was developed in FY 69 and shipped to Meck. Meck-0 testing commenced in March 1969. Meck-1 software, which will test the initial weapons system capability, was in the integration stage at the SDPL, and expected to be completed for shipment to Meck by October 1969. The first Meck system test, a SPARTAN firing scheduled for April 1970, will (ILLEGIBLE) this software.

Design definition of the PAR was completed in September 1968 and development of long leadtime and critical items was initiated. General Electric, subcontractor for PAR development, began assembly of the PAR Limited Engineering Development Model (LEDM). This brassboard model will consist of a 24-element active array with a full string of PAR sensor equipment. The LEDM will supply the test bed for operational and life testing of PAR equipment groups.

The Meck MSR became operational with power turn-on in May 1968. Full power operation was achieved in January 1969 with full peak and average power radiated through the antenna for several hours without failure. Subsystem tests of the antenna, transmitter and receiver were in process and would continue through the first half of FY 70, to demonstrate the operational capability of the MSR/ MSDP to support Meck system testing.

A significant event of this year for the SAFEGUARD System Command was the relocation of the Command from Redstone Arsneal to the new headquarters building in Research Park, Huntsville, AL. The move took place in the first two weeks of January 1969, and dedication ceremonies were held on 8 Feb 69. An open house for friends and families of employees followed. The SAFSCOM Headquarters building, begun in April 1968, was constructed by a private contractor and leased to the General Services Administration. The building has some 300,000 square feet of office space and an annex immediately adjacent to the headquarters which is occupied by the U. S. Army Engineer Division, Huntsville. With the move of U. S. Army SAFEGUARD Logistics Command and Advanced Ballistic Missile Defense Agency into the SAFSCOM headquarters in April and May 1969, all Huntsville-based SAFEGUARD organizations are now consolidated in one location.

SUMMARY OF THE SAFEGUARD PROGRAM, FY 70

BG Robert C. Marshall was named the new Commanding General of the SAFEGUARD System Command following the retirement of BG Ivey O. Drewry on 31 July 69.

During the summer of 1969 the SAFEGUARD System, and antiballistic missile development in general, were subjects of intense interest by Congress, press media, and the general public. Many weeks of Congressional Committee hearings and over a month of heated debate on the Senate floor preceded a vote on the Administration's proposed SAFEGUARD Program for FY 70.

On the date that the SAFEGUARD authorization came before the Senate for voting, 6 Aug 69, an unusual perfect attendance of 100 Senators was recorded. Several amendments which would have terminated SAFEGUARD deployment were narrowly defeated. The final key vote tallied a 50-50 tie, allowing the SAFEGUARD program to continue.

In January 1970, President Nixon, after annual review of the SAFEGUARD System, announced the Administration's program for further SAFEGUARD deployment in FY 71: continue the previously approved sites at Grand Forks, ND, and Malmstrom, MT; an additional third site at Whiteman AFB, MO; and advance preparation at five additional sites. The Senate Armed Services Committee in June 1970, however, approved the additional site at Whiteman AFB, advanced preparation at Warren AFB, WY, and deleted funds for advanced preparation at any other site.

The SAFEGUARD System began to be discussed in a new role: as a "bargaining chip" in the Strategic Arms Limitation Talks between the U. S. and the Soviet Union which were initiated in November 1969. Secretary of Defense Melvin 0. Laird declared that a unilateral cut in SAFEGUARD funds, or discontinuance of the ABM deployment would impair the U. S. position (ILLEGIBLE) talks. A limitation of the ABM defense of both nations was considered a likely area for potential agreements between the U. S. and the Soviet Union.

Technical progress in SAFEGUARD System weapons continued to be good, with initial Meck integrated system testing at the Kwajalein Missile Range (KMR) perhaps the most important technical milestone. The Meck Test Program, projected for a 5-year period, was designed to demonstrate capability of the Missile Site Radar (MSR), Missile Site Data Processor (MSDP), and the SAFEGUARD missiles to function as an integrated system. Space point and live intercepts for both SPARTAN and SPRINT, remote launch tests of SPRINT, and salvo firings of both missiles have been planned. PAR interfaces will be simulated.

The last SPARTAN development flight was successfully conducted at KMR on 15 Dec 69, with all missile and warhead objectives achieved. A total of 14 SPARTAN missiles were flight tested in this development program, the first in March 1968. Eleven full-duration flights were achieved; three tests were terminated early due to in-flight failures and one additional launch attempt failed. The first integrated system test at Meck Island (Mission M1-1), attempted on 14 Apr 70, failed due to loss of MSR track and subsequent auto destruct of the SPARTAN missile. An investigation located the cause of failure in an arithmetic control unit of a processor within the missile site data processing system. A hardware solution was subsequently installed to prevent a repeat of this circumstance. Mission M1-1 was re-run on 24 Jun 70, with the SPARTAN successfully intercepting a fixed spacepoint target under guidance of the MSR/MSDP.

The extended range SPRINT missile was flight-tested at White Sands Missile Range (WSMR) for the first time on 22 Jul 69, and all subsequent flights were conducted with the extended range SPRINT. The first SPRINT warhead section/ adaption kit development flight was accomplished in November 1969. Two SPRINT flights in October and December 1959 resulted in premature ignition of the first stage and structural failure. Development flights were suspended pending investigation of these failures, and modifications were made in the launch eject equipment and first stage aft skirt of the missile. Successful SPRINT flight tests were accomplished in Kay and June 1970. Forty one of the planned forty-two SPRINT development flights were accomplished by the end of FY 70; six of these demonstrated warhead/adaption kit objectives as well as missile performance. After the last SPRINT mission, scheduled for early FY 71, SAFEGUARD testing at WSMR will be phased out. All system flight testing will then be within the Meck Test Program.

Very significant verification of MSR capability was achieved in FY 70. A major milestone occurred in late November 1969 when satellite "targets of opportunity" were acquired and tracked by the Meck MSR. This was the first automatic tracking of high velocity targets under control of Meck test track software. Further tracking demonstrations followed and in December 1969, the MSR successfully acquired and tracked an ICBM launched from Vandenburg AFB, CA.

The PAR Limited Engineering Development Model (LEDM) was a brassboard model constructed in lieu of a prototype PAR, at the General Electric Syracuse plant. The LEDM was completed in August 1969 for operational testing to commence. All groups of PAR equipment will be tested prior to critical design reviews and release to production. Planned LEDM testing was about 57% complete at the end of FY 70.

Data processing subsystem development, both hardware and software, was approximately on schedule. Operating system and support processes have been checked out and delivered to support test and tactical software development.

SAFEGUARD software was under development at Bell Telephone's Whippany, NJ, SAFEGUARD Data Processing Laboratory. A facility for integration of tactical software, designated the Tactical Software Control Site (TSCS) was begun in 1970. The TSCS will eventually comprise two separate systems of PAR and MSR sensor equipment, data processing hardware for each, and some communications equipment. This will essentially duplicate a tactical site. A "basic TSCS" became operational in May 1970 with a minimum hardware data processor configuration. A new building was under construction in Madison, NJ (scheduled for completion in April 1972) which will house the total PAR and MSR TSCS equipment.

Multiprocessor operation of SAFEGUARD data processing hardware was successfully demonstrated in FY 70, both at the SAFECUARD Data Processing Laboratory and at the Meck missile site data processor. Four processors were installed at Meck in November 1969 , and computer throughput, using one, two, three and four processors was subsequently measured.

Meek-Zero software, providing checkout of the MSR, its data processor, and the SAFEGUARD missiles as an integrated system, was delivered to Meck in early FY70. Meek-Zero testing was essentially completed by February 1970. All Meck-1 software processes were delivered to Meck by December 1969 in preparation for the commencement of system testing in April 1970.

Turning now to SAFEGUARD site deployment, FY 70 saw the commencement of construction at both the Grand Forks, ND and Malmstrom, MT sites. Selection of the sites in these areas was publicly announced in October 1969 and field offices were opened at both locations.

On 31 Mar 70, Morrison-Knudsen Company and associates were awarded a contract for $137,868,850 for construction of the PAR, the MSR, their associated power plants and certain other support facilities at the Grand Forks site. Three bids were received for this competitive award, ranging from the winning low bid of $137.8 million to a high of $181.2 million. Ground was broken at the PAR site on 6 Apr 70.

It was decided to award advance construction contracts for the Malmstrom site, rather than a single large contract, in order to match schedule requirements with available funds. Advance work such as excavation, access roads, and base slabs for the tactical buildings commenced in May 1970; follow-on contracts were planned for award in Apri 1 1971. The Watson Construction Company was the successful low bidder ($3.4 million) for initial construction at the MSR site. A contract in the amount of $4.7 million was awarded to the joint venture of H. C. Smith Company and Amalco Corp. for initial work at the PAR site. These contracts were awarded on 4 May and 19 May 70, respectively, and ground breaking took place shortly thereafter at the Malmstrom site.

TEST FIRINGS OF THE SPRINT MISSILE (NOVEMBER 1965 THROUGH MAY 1970) (U)

TYPE & SERIAL NO OF MISSILE

DATE

OBJECTIVES & RESULTS

FLA-1 (Flight 1)

17 Nov 65

The first guided flight of the SPRINT missile. The test verified compatibility of the eject and flight systems, missile in-flight communications, and the ability of the guidance and control systems, structure, heat shield, and motors to perform in actual flight environments. A maximum velocity of 10, 223 fps at 10, 000 feet altitude was achieved.

FLA-2 (Flight 2)

25 Jan 66

Launch eject and first and second stage burning ay seared normal; however, pitch-over angle was greater than predicted. Planned dive commands were transmitted at 5. 2 seconds and initiation of dive was visually observed. Malfunction of missile autopilot resulted in self destruct at 5. 85 seconds.

FLA-3 (Flight 3)

15 Mar 66

Launch order was given, but the flight was aborted due to a major alarm generated by the failure of thrust vector control (TVC) valve No 3 to close in the allotted time during the launch sequence. An in-cell explosion occurred approximately 23 minutes later as a result of heat generated by the normal firing of the missileborne gas generators. The missile and cell were completely destroyed. The cell was to be rebuilt, with the target date for completion January 1967.

FLA-4 (Flight 4)

3 May 66

The missile impacted 1200 feet north and east from the launch site. Telemetry records indicated that feedback signals from TVC valves 2, 3, and 4 were lost at certain time intervals. The crater caused by the impact was approximately 30 feet wide and 7 feet deep, and the south side of the hole showed evidence of an explosion.

FLA-5 (Flight 5)

2 Aug 66

The missile departed radically from the planned trajectory and the flight safety system automatically destroyed it at 2.035 seconds. However, the test objectives of the eject and first stage propulsion systems were met, and operation of the flight safety system autodestruct mode wa6 demonstrated for the first time. The flight path error was due to a malfunctioning rate gyro.

F LA-6 (Flight 6)

3 Nov 66

The flight was prematurely terminated at 0. 960 seconds. When the first stage motor dome ruptured, the missileborne flight safety system operated and segmented the missile. Early failure prevented accomplishment of all but eject, launch phase, and initial pitchover objectives.

F LA-9 (Flight 7)

18 Apr 67

Eject, velocity, and pitchover of the missile appeared normal. However, the flight was terminated at 4. 5 seconds. Recovered parts showed evidence of some burning inside the second stage aft skirt.

FLA-10 (Flight 8)

23 May 67

First stage flight, including pitchover, appeared normal. Separation and second stage ignition occurred, but the flight was terminated early in the second stage. A telemetry loss at 3 seconds resulted in the Target Intercept Computer automatically transmitting a destruct signal at about 4 seconds.

FLA-8 (Flight 9) (Planned)

27 Jun 67

The missile was counted down to launch, but did not eject from the cell. The flight was aborted because thrust vector control valve No 2 did not close within its allotted time. Slow thrust vector control valve closure was also the reason FLA-3 was aborted.

FLA-8 (Flight 9)

18 Jul 67

Flight was terminated at 4.433 seconds. Missile performance during eject, first stage flight, and up to second stage tail-off was essentially as predicted. Test objectives achievable within the time frame of missile flight were all met.

FLA-11 (Flight 10)

8 Aug 67

This test was completely successful, with the entire trajectory very close to that predicted. This was the first missile to execute successfully a second stage maneuver command.

FLA-13 (Flight 11) (Planned)

28 Aug 67

Launch was attempted but aborted. The squibs for the gas eject generator malfunctioned.

FLA-12 (Flight 11)

19 Sep 67

The launch sequence through first stage burnout appeared normal; however, flight was prematurely terminated shortly after two seconds. Termination was due to failure in the missile guidance set which triggered fail-safe.

FLA-7 (Flight 12)

10 Oct 67

The first SPRINT flight using the closed loop guidance. The flight was fully successful and accomplished the first intercept of a space point, at an altitude of 20, 000 feet.

FLA-14 (Flight 13)

31 Oct 67

The missile in-flight performance was essentially as predicted and all flight objectives achieved.

FLA-15 (Flight 14)

20 Nov 67

After a normal countdown, checkout and launch, the flight was terminated prematurely during second stage burning at roughly 7 seconds after launch order. Investigations indicated that one of the Target Intercept Computers failed to correctly interpret the SEMTR data.

FLA-13 (Flight 15)

11 Dec 67

Eject, first stage ignition, separation and second stage ignition occurred as planned, and full missile flight time was achieved. All planned orders were transmitted with the missile responding as programmed.

FLA-16 (Flight 16)

5 Feb 68

The flight was prematurely terminated just after first stage separation, A computer programming error resulted in erroneous gain commands and subsequent system instability which caused missile breakup.

FLA-17 (Flight 17)

26 Feb 68

Flight through planned destruct, including three planned maneuvers, appeared flawless. This was the first flight to use the tactical cell closure and tactical second stage motor. The flight also demonstrated the ability of the interceptor to respond to maneuver commands within specified time limits.

FLA-18 (Flight 18)

25 Mar 68

The missile ejected and first stage ignited. Pitchover was initiated as planned but not terminated; the missile completed a full loop and impacted the ground nose -first, approximately 500 yard6 north of the launcher.

FLA-19 (Flight 19)

22 Apr 68

Ejection and first stage ignition, pitchover, and first stage flight appeared normal. Separation did occur but apparently involved a transient and early second stage ignition. The flight terminated at 2. 44 seconds when flight safety destruct occurred.

FLA-20 (Flight 20)

27 Jun 68

This was a full duration flight, with all test objectives successfully accomplished. The trajectory was designed to subject the missile to the most severe thermal environment possible at WSMR. As part of the planned experiment, the missile tumbled 2 1/2 times end over end before destruction. The condition of the recovered hardware indicated that this maneuver minimized impact damage.

FLA-21 (Flight 21)

29 Jul 68

A successful flight, achieving all objectives. The S-band telemetry system, in its first flight test, provided data throughout the flight.

FLA-22 (Flight 22)

22 Aug 68

This flight was designed to demonstrate missile structure and control system integrity through the intercept of a space point and to determine missile response to a switch plane maneuver.

FLA-23 (Flight 23)

9 Sep 68

This flight provided a severe test of the missile hydraulic system; pressure readings showed that the system functioned normally and full control capability was maintained.

FLA-24 (Flight 24)

8 Oct 68

The objectives of demonstrating the missile's structural and control system integrity through the intercept of a space point, were fully achieved.

FLA-25 (Flight 25)

28 Oct 68

Designed primarily as a missile control system endurance test, the missile responded as predicted to cyclic commands issued to test the endurance of the hydraulic control system.

FLA-26 (Flight 26)

2 Dec 68

The flight was prematurely terminated at approximately 2.3 seconds. Flight termination resulted from a malfunction in the missile autopilot, causing the pitchover angle to increase to 92. 9 degrees from vertical versus 38 degrees predicted. FLA-26 autopilot was recovered in good condition.

FLA-27 (Flight 27)

10 Feb 69

This was the first of three staging experiment flights to verify wind tunnel test data by a controlled staging maneuver which was accomplished by introducing moderate sized vane deflections and staging transients. All flight objectives were successfully achieved.

FLA-30 (Flight 28)

17 Mar 69

Performance of this flight was as predicted from launch until approximately 8 seconds into the flight. A rupture of the second stage gas-generator then caused loss of missile control.

FLA-28 (Flight 29)

21 Apr 69

A successful flight designed to obtain aerodynamic and environmental staging data and to determine missile stability at second stage ignition. All objectives were achieved.

FLA-31 (Flight 30)

26 May 69

This flight provided a severe test of the missile hydraulic system. All objectives were achieved.

FLA-29 (Flight 31)

23 Jun 69

The third staging experiment flight designed to acquire environmental data resulting from second stage ignition at minimum separation distance. Missile responded properly to all commands and all flight test objectives were achieved.

SPRINT F LT-32 (FLA-32)

22 Jul 69

Designed primarily to demonstrate an extended range controlled flight time duration of 51 seconds and to perform an overall evaluation of the MOD III System performance. No missile problems were experienced during the countdown and missile performance was as predicted from launch until end of programed flight. All flight test objectives were achieved.

SPRINT FLT-33 (FLA-35)

15 Sep 69

Designed primarily as a verification round of the MOD III Missile configuration and extended range flight time capability. No missile problems were experienced during the countdown and missile performance was as predicted from launch until end of programed flight. All flight test objectives were achieved.

SPRINT FLT-34 (FLA-36)

6 Oct 69

Designed primarily to obtain intermediate to high angle of attack data during the period of high Mach number environment. No missile problems occurred during the countdown. Missile failure occurred during the eject phase as an apparent result of eject piston dome rupture. The missile was destroyed at 2.436 seconds by RF destruct command. No missile test objectives were achieved.

SPRINT FLT-35 (FLA-38)

23 Oct 69

Designed primarily to obtain intermediate to high angle of attack data during the period of high Mach number environment. This test demonstrated the ability to sequentially countdown two missiles (FLA-38 and FLA-34) and to countdown a missile

SPRINT FLT-35 (c

on. )

(FLA-34) after being subjected to the environment of a missile (FLA-38) launched from an adjacent cell. All desired aerodynamic data were obtained as the missile responded satisfactorily to all maneuver commands. All test objectives were achieved.

SPRINT FLT-36(FLA-33)

6 Nov 69

Designed primarily to subject the warhead/adaption kit (WH/AK) unit to the extremes of the aerodynamic environment effects and to verify the functional integrity of the airborne telemetry system. No missile problems occurred during the countdown. Missile flight was normal until approximately 5 seconds when the missile experienced severe lateral accelerations resulting in missile breakup. Good warhead telemetry data was obtained until missile breakup.

SPRINT FLT-37 (FLA-34)

1 Dec 69

Designed primarily to subject the WH/AK unit to the extremes of the aerodynamic environment effects and to verify the functional integrity of the airborne telemetry system. Missile destruct occurred during launch eject as a result of eject piston dome failure, which was similar to that of FLA-36. The missile was destroyed at 12.3 seconds based on programed 5,000 ft. minimum altitude criterion.

SPRINT FLT-38 (FLA-39)

19 Mar 70

Designed primarily to test the WH/AK configuration consisting of an instrumental warhead and adaption kit with an associated airborne telemetry system. Terminated prematurely at 4. 38 seconds when the missile experienced severe lateral accelerations and subsequent structural breakup. The ability to launch the missile from RF test request was demonstrated.

SPRINT FLT-39 (FLA-42)

7 May 70

Designed to obtain flight teat data on the warhead section development and the evaluation of missile performance. The missile was aborted in the cell during the attempted launch due to noise recorded during the vane null check.

SPRINT FLT-39 - (FLA-40)

28 May 70

TEST FIRINGS OF THE SPARTAN MISSILE (MARCH 1968 THROUGH DECEMBER 1969) (U)

TYPE & SERIAL NO OF MISSILE

DATE

OBJECTIVES & RESULTS

KT-01 (800003)

30 Mar 68

The first SPARTAN flight, with, all test objectives achieved. The missile response to guidance commands was normal; second stage burnout was completed at 23. 8 seconds and the missile left the atmosphere, after which third stage separation and performance were as programmed. At 208 seconds into the flight, the HPU turbine failed structurally. The flight was terminated at 277.7 seconds.

KT-02 (800004)

22 May 68

In the second SPARTAN flight, the missile followed the long range, medium altitude, atmospheric trajectory planned. The flight was terminated at 134. 6 seconds as a result of the planned activation of the manual destruct system.

KT-03 (800005)

7 Aug 68

The third full-duration flight of the SPARTAN missile. All objectives were achieved during the endoatmospheric test in a total of 152. 5 seconds flight time. The modified ZEUS DM15C hydraulic power unit, flown as an interim measure pending availability of the tactical design, performed satisfactorily.

KT-04 (800007)

16 Sep 68

This flight was unsuccessful due to malfunction in the fin position demodulator, causing uncontrolled oscillations in the yaw control system shortly after second stage motor ignition. Destruct was accomplished by a discrete command from the SPARTAN Guidance Computer at 18. 55 seconds.

KT-05 (800006)

21 Nov 68

Only a few of the planned objectives were attained in this flight, due to premature destruct, at 13. 8 seconds. Failure occurred in the aft end of the second stage.

KT-06 (800008)

6 Feb 69

The purpose of the test was to evaluate thermodynamic integrity of the missile, overall missile performance, and subsystem operation during a medium range, low altitude, atmospheric trajectory flight. First and second stage motors performed normally, third stage motor was not ignited. All flight objectives were successfully achieved.

KT-07 (800009)

22 Mar 69

Test was aborted during launch countdown due to a battery failure. This missile will be returned to the contractor for checkout; to avoid delay, Missile No 800010 will be used for KT-07.

(800010)

25 Apr 69

All flight objectives were achieved in this test to evaluate two stage missile thermodynamic integrity and overall inflight missile performance and subsystem operation on a long range, medium altitude atmospheric trajectory.

KT-08 (800009)

18 May 69

A successful flight test to evaluate overall performance on a long range, medium altitude, exoatmospheric trajectory. The end of the planned flight occurred at 403 seconds at a range of 395 nautical miles.

KT-09 (800011)

4 Jun 69

Only a few of the objectives were achieved due to premature termination of this flight at 15. 1 seconds. Malfunction of the hydraulic pumping unit gas generator shut-off valve initiated the sequence of events that led to missile destruct.

SPARTAN KT-10 (Msl 800013)

16 Jul 69

Designed to evaluate the overall inflight missile performance and subsystem operation on a medium altitude, long range, exoatmospheric trajectory. The missile flew on the intended trajectory, and all flight objectives were achieved.

SPARTAN KT-11 (Msl 800014)

31 Jul 69

Designed to evaluate the overall missile performance and subsystem operation on a long range, low altitude, exoatmospheric trajectory and to provide environmental data for application to warhead development. All missile development and warhead system measurement objectives were achieved.

SPARTAN KT-12 (Msl 800012)

13 Aug 69

Test was conducted unsuccessfully. The first stage motor ignition was prevented during the launch countdown sequence. An inspection of the missile hardware revealed that the explosive harness connections had been interchanged between the HPU and the third stage motor. This resulted in the third stage motor being ignited when the HPU ignition signal was sent.

SPARTAN KT-13 (Msl 800016)

17 Oct 69

Designed to all-systems test of the two stage missile configuration in the atmospheric mode and to evaluate the warhead/adaption kit (WH/AK) in a severe atmospheric heating environment. All missile, WH, and AK objectives were achieved.

SPARTAN KT-14 (Msl 800015)

25 Nov 69

Designed to evaluate the thermodynamic integrity and overall performance of the missile during a long range, medium altitude, atmospheric trajectory. The flight was terminated at 211 seconds after completion of all missile test objectives.

SPARTAN KT-15 (Msl 800017)

15 Dec 69

Designed to evaluate the performance and subsystem missile operation and to obtain flight environment data on WH section dynamic components during a long range, medium altitude, exoatmospheric trajectory. The flight was terminated at 440 seconds after achieving all missile, WH, and AK objectives. This was the last of the programed SPARTAN development flights.

SPARTAN M1-1 (Msl 800018)

14 Apr 70

Designed to verify that the MSR and associated MSDD was capable of guiding a missile through a predetermined space point. Missile launch occurred with system performance approximately as predicted until 19. 1 -seconds into flight Although MSR/missile objectives were demonstrated to a certain degree, the mission objectives were reassigned to mission M1-1A.

SPARTAN M1-1A (Mel 800019)

24 Jun 70

Designed to demonstrate the ability of the MSR, MSDP, and SPARTAN subsystem to work together in launching and guiding a SPARTAN missile to a space point. All primary and secondary mission objectives were achieved.
