G. There arc critical uncertainties in our knowledge ofnd deployment in thc antiballislic missile (ABM) field. From thc evidence now available, however, certain general conclusions can Iw drawn; first, theffort has been extensive and of long duration, and thc USSR several years ago probably solved thc technical problem of intercepting ballistic targets arriving singly or in small numlwrs; second, some initial ABM deployment activity was probably begun as long agout both the deployment and BAD programs werenterruptedmodified; third, th-gniludend thc probable early deployment activity pointtrong Soviet desire to obtain ABM defenses rapidly;ew antimissile missile (AMM) has appeared, and some additionalactivity may now be underway, but the USSR docs not have any operational defenses against strategic ballistic missiles today,

Thc new AMM which wasby the Soviets is probably designed to conductintercepts at considerable ranges,arge nuclearto achieve its kill. We believe, however, that thc Sovietsnot conducted many AMM firings to exoatmosphericand that they have probably not attempted full systeminterceptions at these altitudes.

Recent Defensive Deployments

However, wethat the initial design has been changed, Wc cannotnature of this change, or whether it was caused byealization lhat the system was vulnerable toaids, or important new developments in the statc-of-theare similarities between new construcbon at one of thecomplexes and two recently discovered defensive complexes un-

F. We arc unable to associate the new complexes with any systems equipment, and any explanation for the mission of these complexes and the modified Leningrad complex is open to some doubt. There is

to defend against aerodynamic vehicles. On the other hand, we have noted intensive Soviet research on missile defenses for several yean and indications that the USSR has been working toward new andABM capabilities. In light of this factor and otherwe think there are also persuasive reasons for believing that thc new complexes are related to missile defense. However, any judgment at this time on their mission is in our view premature,O) C. We have observed at Moscow three developments which may indicate ABM deploymentarge radar now undercould be the acquisition and early target tracking element of an ABM system. Other.facilities also under construction^could serve as the final target tracking and missile guidance element.ites which are now being modified could be used as the AMM launchfor the systems. However, the activities we have observed thus far may not be related, and some of them may represent improvements in Moscow's defense against aerodynamic vehicles orpace function. The missile to be employedajor unknown; thedisplayed AMM could be used at Moscow to conduct exoatmos-pheric intercepts of ballistic missiles, perhaps at distances of several hundreds of miles from the city. In sum. we continue to believe that the Soviets may be deploying ABM defenses at Moscow, but we do not yet understand how the installations we have observed would function as an ABM system. )

ABM Proipflcts

H. If ABM deployment activity is now underway at either Moscow or the other locations we have noted, the USSR is likely to have some initial strategic ABM defenses operational within the next two years or so. Limited deployment, especially at Moscow, couldpecial, highest-priority effort to defend the Soviet capital with an early and still unproved system. But widespread ABM deployment activity, whenever it occurred, would imply that the Soviets consider their ABM

We cannot exclude this possibility, but oursuggests lhat thc Soviets have been proceeding cautiously since they modified their program. )

I. In considering whether to provide ABM defenses for many of their urban-industrial centers and other targets, the Soviet leaders will have to weigh the great cost of such an eflort against thc likelyof the ABM systems available. Area defenses might offer considerable savings over point defenses, but we cannot be sure of this and in anyajor commitment of resources would beThe Soviets may defer widespread deployment pendingork on existing systems, or in the hope of achieving better systemsater date. They might even decide that the cost of large-scale ABM deployment would not be commensurate with the protection it could offer against anticipated Western strikeWe are certain that the Soviets will push ahead withffort, but we cannot forecast whether or when they will achieve ABM systems with capabilities and costs justifying widespread deployment.

We expect, therefore, that Ihe Soviets will continue to spend large sums on air defense despite the planned deerense in the size o( the US strategic bomber force over the nest few years.

In addition, the Soviets have been faced for tome yean with tlie certain knowledge that as this decade advances, ballistic missiles, presenting wholly new defensive requirements, will comprise the main strategic threat to the USSR. The ballistic missile threat not only poses the question of how much additional effort to pour inlo improved defenses, but also raises the problem of whether, regardless of resources commit led, it is feasible for Ihe Soviets to create nndefense of major targets against the US strategic strike forces.


The Soviet air defense mission is the responsibility of the PVO Strany (Anti-Air Defense of thehoseeputy Minister of Defense, is ranked with the heads of the ground, naval, air and strategic missile forces. The PVO is composed of three major elements, each of which perforins one of the key functions of the sir defense mission. Le, early warning and control, interceptor, and surface-to-air missile (SAM) operations. In addition to forces directly assigned to the PVO. other Soviet forces which can contribute toair defense mission are also operationally available lo this command.

In addition to air defense, the commander of the PVO probably is assigned the missile defense mission. The Soviets have referred to the existence of PRO (Anti-Rocket Defense) units, and have usually Indicated that these units are subordinate to. or at least integrated with, the PVO Strany. The Ministry of Defense implements the civil defense program, but such operations are not subordinate to tho PVO.

We estimate that there an nowadars deployed atperational sites in Ha USSR. Thb system provides overlapping radar coverage of most of the nation; coverage is very dense wetl of the Ural* and in peripheral areas. Almost all sites have at least two radan and many are equipped with Eve lo seven wis, most of whtchin different frequencyhe resulting density of coverage heightens the probabdity of detection, and the frequency divenificanon provides some defense against electronic counlermeainres.

he altitude coverage of thc. Soviet EW system eicccdi the combat ceiling of any US aircraft now in service. Under optimum conditions, the Soviet EW system could detect and track aircraft flying at medium or high altitudes atm. away from Soviet territory, and under normal conditionsand tracking of enemy aircraft flying at such altitudes is virtually assured. beyond the Soviet borders. The use of supersonic aircraft and cruise missiles, because of their very high speeds, will reduce the warning time provided by this ryitem. The detection range of the EW system is progressively reduced against aircraft penetrating at lower altitudes. Moreover, even where detection of low altitude penelrators occurs, the system is unlikely to be able to accomplish continuous tracking of an intruding enemy aircrafteet

S As the Soviet EW systemuality, the number of radar sites probably will be gradually reduced. We estimate that0 the rangeof the Soviet EW system will be limited only by the radar boruon Tine of sight. The Soviets will place increased emphasis on the problem of detecting and tracking low altitude targets. Radars bettor able to cope with such targets probably will be deployed, particularly in border areas and along likelyroutes. Nevertheless, radar pcjformance at low altitudes will remain limited.

that CCI range capabilities vary frotn aboutun. lon (lie radar employed at tlie site. Soviet CCI setsigh altitude coverage which eitcodn the combat ceilings of all US aircraft.

Thc semiautomatic data system may be modified to increase traffic handling capabilities. 'All new model Interceptors brought inlo service probably will be equipped to operate with the data link.


n the Soviet air defense system, interceptor aircraft constitute the first line of active defense, performing both area and point defense roles. We believe that during the past Iwo years, the Soviets have been placing greater emphasis on improving the mobility and coverage of tlveir interceptor force, especially through the use of forward deployment tactics. Air defense training hasIncluded the dispersal and redeployment of PVO aircraft.

The Soviets are likely to continue to rely on lives the principal SAM system for air defense during the period of this estimate.

The most recent modifications, made during Ihe past year, were probably designed primarily to increase its range and improve its capabilities against supersonic targets.

The Soviets expect that their air defense system will have to contend with electronic countermeasurcshe density of EW/CCl radar sites, the frequency diversification at these sites, and the probable use of microwave links and coaxial cables all reduce the vulnerability of tho Soviet a* defense system to ECM. The Soviets may employ frequency diversification in their semUutomatlc data transmission systems.

Tlic massive deployment of air defenses over many years Indicates the Ingh priority that the Sovicu have assigned to ll* straiegic defense mission. The general Soviet concept has been toefense in depth for their major Centers of population nod national power. In addition, they haveendency lo deploy delemive systems having some capabilityortion of the threat, rather tlian to wait until more effective defenses can be developed. The expenditure of resources on strategic defenses has been very large; in recent years it has amounted to about one-fifth of the expenditures which we can attribute to the major military missions.

The foregoing generalizations are well-supported by the varioussummarized in preceding sections of (his paper. In addition to those developments, wc believe that the Soviets have been working actively on other new systems for strategic defense. The present state of our evidence and analysis is such that we are not able to estimate with confidence the precise nature of much of this work. However, some perspective On Soviet thinking about icquircmcnts for new strategic defense systems it available from classifiedliterature of recent years.

Ami-Ballistic Missile (ABM) Systems

Articles appearing in the classified Soviet military literature1 argued that an ABM system to defend against strategic missiles should be capable of performing intercepts at high altitudes and long ranges

In those few articles discussing ballistic missile defenseldl wo are cognizant, tbe most practical mctlwd of destroying an incoming ballistic missile wa* said to be caratrrmphcric. intercept prior toibead'* entry into thu dense layen of the atmosphere. One Soviet general asserted that minimum intercept altitudes against ICBMs and IflBMs should be fromoepending on tlie yield of the enemy warhead. Another Soviet general observed thnt it would be necessary lo have antimissile missiles (AMMs) capable of ranges on tlie orderun. and altitudes of not less lhaii.

Some officers, according to classified Sovietbelieved that theissile could be mod.Red for use againstmissiles. In addition, the Soviets have repeatedly referred to the(first displayedeapon capable of being employedmodern means of aerial and spacehich suggests that thisoriginally intended to serve asAM and an AMM.


development of Soviet defensive weapon systems has beenat two test ranges. Kapustin Yar and Sary Shagan. The activitiessystems at Kapustin Yar began in the; to the best ofthese activities have been directed toward the developmentof SAM systems and for training. Sary Shagan has servedan ABM development center, although it has also supported other mspace piograms and work on SAM systems has been conducted there.

Surface-to-Air Missiles

have no specific evidence of any SAM system being, andowever, some new SAMs (eg, the Canef tacticalappeared in Soviet parades, and they may already be in the earlydeployment. We have therefore thoroughly examined our ability toidentify the development of SAM systems,ong-rangeand we bave concluded that such systems could have beentested without our knowledge.

However, we cannot determine whether tliey haw made any atiempt to create ICBM re-entry angles or velocities during any ol llic tests. We hnve no evidence that thc Soviets havo conducted tests involving thc use ofultiple warheads, or oilier penetration techniques at Sary Shagan. and wc think it unlikely.

at face value, thc evidenceoncentration on tlwintercepting medium-range missiles. The Soviets have not attemptedagainst ICBMs. but they have, of course, obtained considerable datare-entry characteristics from their many ICBM tests. We believe thathave concluded that thc problem of intercepting ICBMs is notfrom that of intercepting medium-range missiles, except thatranges arc required for thc acquisition ond tracking of an ICBM.

Rodor Development end Deployment

Important part ofork at Sary Shagan has been theof large radars, tlie Hen Roost and Hen House, wr-ch we^believcfor initial testing in

to Soviet development of radars which scan their beams electronically rather than by physical movement of rise antenna. Large radars employing thisare particularly applicable to ballistic missile early warning, to long-range acquisition and early target tracking of ballistic missiles, and to detection and tracking of satellites. We believeumber of these large radars are under construction in the USSR.

e believe two Hen House-type radars are now under construction on the Kola Peninsula. These radars probably will serve as ballistic missile early warning radars, but they couldpace surveillance- function as well. They could provide warning of US ICBMs directed toward westernfor example.inutes In the case of Moscow. Additional radars in other locations would be required to provide similar warning of missile strikes against other target areas In tbe USSR. We have no evidence of the construction of radars suitably located for this purpose, but we estimate that the Sovietswilt extend their ballistic missile early warning coverage. We believe that the Soviets require about two or three yean to construct radars of this type in the field; the ones in the Kola Peninsula will probably be in operation

We believe that the Criffou missile was developed for use at the large complexes which the Soviets have been constructingniogrsd since the winter. (See later paragraphs.)


n4 parade In Moscow, the Soviets displayed what they described as an antimissile missile capable of destroying ballistic missiles "at great distances" from their targets. Preliminary analysis of parade pho-tograohy leads us to accept an AMM role for this missile. From its site and what can be seen of its booster engines, we think that it is likely toarge warhead and to be designed to perform exoatmospheric Intercepts. Very preliminary calculations indicate that the missile in-the-caniiter may be able to accomplish intercepts at altitudesew hundred miles and at ranges of several hundred miles from its launch point,arhead in the megaton range.issile could also be used in an antisatellite role.

ome new AMM may have been tested initially at Sary Shagan as early as the end. There is some chance that the Soviets could have conducted propulsion or component testing of an exoatmospheric system,est program Involving moreew AMM firings would probably have been detected. All things considered, we believe that the Soviets have probably not conducted many AMM firings to exoatmospheric altitudes, and lhat they have probably not attempted full system tests involving interceptions at these altitudes.

ur evidence shows that the Soviets approach the testing of missile systemstrong presumption that the tests will be successful and that the system will be deployed. In fact, wc have observed initial operational deployment of certain missile systems at about the same lime as tost firings began.

onstruction of three new defensive complexes was begun at Leningrad in the winter. While our evidence has never been adequate toirm Judgment about live function of the Leningrad facilities, we have estimated for the past several years that they probably comprised ao ABM system which would be capable of engaging both IRBMs and ICBMs. Last year we estimated that the Leningrad system mightapabilitymall number of reentering objects arriving at about the same timeither more than one missileissilemall number ofut that it would probably have little capability against saturation attacks orpenetration techniques."

e believe that the Leningrad system was originally designed toapability against ballistic missiles, and perhaps against aerodynamic vehicles as well, bul thst the initial design has been changed. We cannot determine the nature of this change, nor can we determine whether It was caused by serious technical difficulties, the realization that the system was vulnerable to penetration aids, or important new developments in thc state-of-the-art. There are similarities between new construction at one of thc Leningrad com-

(ilexes and recently discovered defensive complexes under construction aT" Tallin and Cliercpovels in northwestern USSR. (See latern light of these similarities, at least these three complexes may now be intended for (lie deployment of Uie same defensive system. However, we are unable to associate the new complexes with any systems equipment, and anyfor the mission of these complexes and for the modifications al Leningrad is open to *omc doubt.

Tallin and Cherepovets

Wu know of no Installations in tho vicinity of Tallin and Cherepovets which would call for this selection as early sites for an ABM system or even forew SAM system. -In order to function at part of an area ABM defense for thc western urban-industrial region, the complexes at Tallin and Cherepovets would need toissile with long-range, exoatmospheric capabilitiesompatible acquisition AMM. complexes at these locations could defend against both ICBMs and Polaris missiles ontowards Moscow or other key targets in the western region. To defend Moscow from these locations, intercepts would have to be performed at altitudes of.

These complexes, however, could be intended to serveAM role If so, we believe they would beong-range system, and that they may bo thc startarrier torincipal route of US bombers toward the industrial centers of western USSR. The missile used byystem could be the Criffon or some other missile not yet identified. If used with appropriate guidance equipment, the Criffon would probably be effective to ranges on the order. against aerodynamic vehicles at medium and high altitudes.

Thus, there is some support for tho belief that the complexes areAM system to defend against aerodynamic vehicles. On the other hand, wo have noted intensive Soviet research on missile defenses for several years and indications that the USSR has been working toward new and different ABM capabilities- In light of this factor and some of the foregoingwc think there are also persuasive reasons for believing that theseare related to missile defense. However, any judgment at this tirno on their mission is in our view premature.

Thus we have observed under construction at Moscow what may be tltree key elements of an ABM system.

Also, the missile toajor unknown; thecould be used at Moscow

In sum, we continue to believe that the Soviets may now be deploying ABM defenses at Moscow, but we do not yet understand how die installations wo have observed would function as an ABM system.

Bollistk Missile Defense

are critical uncertainties in our knowledge of thend deployment in the ABM field. At this point in time,make no confident estimate about the future prospects for Sovietstrategte ballistic missiles. From thc evidence now avaiisblc,general conclusions can bo drawn:

theffort has been extensive and of long duration, and the USSR several years ago probably solved the technical problem ofballistic targets arriving singly or in small numbers;

some initial ABM deployment activity was probably begun as long agout both the deploymentrograms wereinterrupted and modified;

At tlw Other extreme, it is possible that live recent activity include* two simultaneous ABM deployment programs:efense of Moscow, and the other an area defense of tise western urban-mduitrial region- If ABM dersloyment activity is now underway at either Moscow or the other locations we have noted, the USSR i* Ubely to have some initial strategic ABM defenses operational within the neat two years or so.

Limited deplovment activity, especially at Moscow, couldpecial, highest-priority effort to defend the Soviet capital with an early and stillsystem. But widespread ABM deployment activity, whenever itwould imply that the Soviets consider their ABM systems-good enough to justify extraordinarily large new expenditures. It would indicate that the Soviets had achieveduccesses and. perhaps, that Ihey had taken high-risk production and deployment decbions. We cannot exclude thisbut our evidence suggests that thc Soviets have been proceedingsince they modified their program.

In considering whether to provide ABM defenses for many of their urban-industrial centers and other targets, thc Soviet leaders will havo to weigh the great cost of such an effort against Ihe likely effectiveness of the ABM systems available Area defenses might offer considerable savings over point defenses, but we cannot be sure of thb and in anyajor commitment ofwould be required. The Soviets may defer widespread deployment pendingork on existing systems, or in the hope of achieving better systemsnter date. They might even decide that the cost of Urge-scale ABM deployment would not be commensurate with the protection it could offer against anticipated Western strike capabilities. We are certain that the Soviets will push ahead withffort, but we cannot forecast whether or when they will achieve ABM systems with capabilities and costs justifying widespread deployment.

In addition, the USSR already has the capacity to track its own satellites, utilizing transmissions from them, with greater accuracy than would be provided by the new system. Considering these factors, we think the chances are better than even that the Soviets intend to provide themselves, not onlypace surveillance system, but with an anh'sateliite capability us well.*

The kill mechanism which could be employed by an snctsatellite system depends on the capabilities of its tracking radars and the accuracy andof tho interceptor missile It employs.
