DISCUSSION

I. SOVIET POUCY TOWARD STRATEGIC DEFENSE FORCES

I. Confronted by large and powerful Western strategic attack forces, tbe Soviets haveustained and vigorous effort to improve tlicir defenses. In tlie past several years, snrfacc-to.air missiles and Dsn* generations ofaircraft have been widely deployed Warning and control systemsen expanded and sophisticated. At the same time, the Soviets have pursued lln more advanced air defense systems. And lorecade they havearge-scale, high-priority program to develop antimissile defenses.

oviet expenditures (or strategic defense have grown steadilyn recent years, these expenditures have roughly equaled those for strategic attack, when the major buildup of strategic missile forces was in process. The USSRuch larger share of its military expenditures tu strategic defense duringeriod than did thc US. Manpower allocated to the strategic defense mission has also0 toen at present. This increase occurrederiod of large scale reductions in military manpower.

espite impressive improvements, however. Soviet strategic defensehave not overtaken increasingly sophisticated US attack capabilities. Thus, while the USSR hasormidable capability against aircraft attacking at medium and high altitudes, its air defense systemtill susceptible to penetration by stand-off weapons and to low-altitude tactics. Finally, tlie Soviets must realize that their surface-to-air (SAM) and mterceptor forces and the supporting warning and control elements of their air defensewould be highly vulnerable to attack by missile strikes which they would expect to be coordinated with an air attack against the USSR.

hile thc bulk of Soviet expenditures for strategic defense In tlie past few years has gone to air defense, the character of the US threat has changed. In assessing the future threat, the Soviets undoubtedly consider tbe most pressing problem to be the threat posed by massive and growing US ballistic missile forces, because this threat cannot now be met adequately by either pre-emptive attack or active defense. In addition, the threat posed by bombers has probably not diminished in Soviet eyes. Considering the forthcoming Introdixtion of advanced aircraft by the US, the Soviets probably foresee little reduction In the bomber threat into. Thc Soviets are no doubt also concerned with US activities in space which have military applications.

he Soviets must feel pressed to respond to these USasically deterrent strategy, they are now strengthening their forces for strategic attack, but they are not, we believe, attempting to achieve a

fiircc capability.* In building their forces for strategic defense, theye responding to thc challenges lo their security that they can now see amiballistic missiles, and earth satellites.

Warning ond Control

B There arc now moreadars deployed at wellites In the USSR. These sites have at least two radars and many are equipped with five to seven sets. This deployment provides overlapping radar coverage of most of the nation; coverage is particularly dense west of the Urals and in peripheral areas. The density of coverage heightens the probability ofand frequency diversification provides some defense against electronic countermeasuresut. al the same time, the redundancy of radar coverage Increases thc load on communications and filter centers.

arly Warning. The altitude coverage of the Soviet early warning (EW) system exceeds the combat ceiling of any US aircraft. Under optimumthe Soviet EW system could detect and track aircraft flying at medium or high altitudes at. away from Soviet territory, and under normal

Communications. The Soviet air defense warning and weapons control structureommunications network whichigh degree ofand flexibility. The most important development in air defense communications in recent years has been the spreademiautomatie-data transmission system. The ground-to-ground link of this system has probably been deployed extensively in the USSR and in parts of Eastern Europe. Origi-ivally believed to be associated only with early warning and interceptor control, the system probably is now being used to support SAM operations in someWe believe that the ground-to-air link has been deployed extensively in the USSR and is being used by Soviet forces In East Cermany, Poland, and Hungary. It is also probably being employed by one or two of the Eastair forces

Outlook. During the next tan years, the number of radar sites probably will remain steady or decline slightly. We estimate that the number of radar sets, however, depending on their age and serviceability, will be reduced from the present level perhaps by as much as one-half. The Soviets will probably deploy new radars designed to enhance low altitude and antijamming capabilities. We estimate that deployment of the ground-to-ground link of the semiautomatic data transmission system will be extended, and SAM units will be fully incorporated in the system; the ground-to-air link will be standardon all new interceptors. We believe that the Soviets are developing more fully automated systems for interceptor control which could become operational in the next year or two.

Armament Virtually all of the older Soviet interceptors and some of the current models are equipped wiih guns and rockets. Less than half of thc currently operational Soviet interceptors are equipped with air-to-air missilesor the most part these aircraft are limited to effective attack ranges of less than five nm. and all are restricted to tail chase attack tactics. We believe that tbe Firebar. Fiddler, and other new interceptors will be armed with improved AAMs and radars which will allow these mlerceptors to employattack tactics at effective ranges of more than

Capabilities. The Soviet Interceptor force has good capabilities against subsonic, andesser extent against strperscwuc aircraft attacking at medium and high altitudes, in daylight or under clear air mass conditions. The force has, however, limited all-weather capabilities and poor low altitude capabilities. Despite increased training In low altitude intercepts and attempts to employ the Firebar In this role, the problems of lead pursuit and till chase attack at altitudeseet, sod particularlyeet, remain severe. The Soviets probably also plan to use their Interceptors against air-to-surface missiles, at least as an interim measure,

utlook. Although the present Soviet SAM defenses provide good all-wcatlver, medium- aod high-altitude protection against aircraft and air-to-surface missiles, they are deficient In long-range and low-altitude capabilities. Over tho next few years tbe Soviets will attempt to overcome these deficiencies. They will probably expand the deployment of their new long-range SAM system toarrier defense against bombers and long-range airto surface missiles in the peripheral areas of thc USSR and at some key urbanuch deployment would probablyotalomplexes and eoule-bc completedhe Soviets may seek to meet their requirement for very low-altitude capabilities with improved AAA. We believe it more likely, however, lhat they will develop an improvedew SAM system, although we have no evidence of such development.

III. BALLISTIC MISSILE DEFENSES

or the past decade, the Soviets have been assiduously working to develop defenses against ballistic missiles. ctivities associated with tlve Soviet program continue to be conducted at the large Sary Shagan missile teat center io central Asia. umber of missiles, radars and other systemhave been developed and tested over the years for both tactical and strategic systems. We believe that the Soviets have conducted an atrnosphcric intercept test program, and they have probably investigated exoatmosp^serictechniques as well. It seems likely tbat they have studied both point and area defenses and examined the feasibility of recession and barrage type intercepts. In the field of electronics, (hey have explored the advantages of using relatively low frequencies as well as those higher lo the spectrum; they have worked with large dish-type and phased-array radars. Thus, the scope and diversity of the program have been impressive, but the Soviets liaveexperienced many failures aod frustrations.

We know of no tests that they have conducted specifically for this purpose, but they could have acquired some information On tliese effects without our knowledge from underground tests.

Ocfense of Moscow

We estimate that the Soviets are now deploying an ABM system for thc defense of Moscow. We do not yet know tlx characteristics of thla system, or how it will function. We believe, however, that wc have identiiied some of its key elements. There are several huge radars in the northwestern USSR and facilities in the Moscow area which probably serve the functions of earlytarget acquisition and tracking, and missile guidance. In addition, it is possible that the Galosh missile, which the Soviets displayedswith the system.

The Soviets are constructing very large radars in the northwest, which probably are Intended to function as partallistic missile defense. These dual Hen House radars are being installed at Olenegorsk on the Kola Peninsula and at Skrunda on the Baltic coast, and could be operationalliese radars, developed at Sary Shagan. probably are phased-arrays transmittingelatively low frequency.n thc VHF band. They arc oriented inashion as to be able to detect ICBMs launched from the US toward most targets In western USSR; they will probably also be capable of detecting ballistic missiles launched by submarines In the Norwegian Sea and thc North Atlantic at targets in the Soviet northwest. We believe that these radars willallistic missile early warning function, and may provide some tracking and prediction data for use by AMM launch units.

In addition to the Dog House, Ihe Soviets are continuing to workeries of "triads" located at some of the outer ringites inriad consuls of one large budding and two smaller ones, each probablyhili-type radar atop. We believe that the triads will provide final targetand missile guidance for the Moscow ABM system.

If Caloshimilar missile is to be used, the system is likely to be intended to perform exoatmosprseric intercepts at tanges up toiles. On thc other hand, thc Moscow system may be designed lo use another type of missile and to achieve atmospheric intercepts of incoming warheads. It is even possible that both types of missiles and intercepts are fanned for the; system. Regardless of the system's characteristics, we estimate that ballistic rnissile defenses at Moscow could achieve some capability as earlyut weore likely date for an initial operational apaWity

Prospects for Missile Defenses

The USSR will almost certainly continue (Isffort on antimissile defense. This effort will be directed generally toward countering thc increasingly aocshisticated threat that will be posed by US strategic missile forces. Whatever the present characteristics of the Moscow system, we believe that future defenses will provide for both long-range exoatmospheric Intercept and short-range Intercept within the atinosxibere-

We believe that over the next ten years the USSR will extend Rsdefenses beyond the Moscow area. The evidence is insufficient for us to estimate with confidence the scale or timing of such deployment or towhether point or area defenses will be emphasized. We believe, however, that the Soviets will deploy ABM defenses for major urban-industrial areas

IV. ANTISAIElLire DEFENSES

he Sovi 'continue to acciuc the US of employing ita space vchiclei mainly for reconnaissance and espionagend their traditional concern lor military iccrecy gives the Sovicii an incentive to develop defenses against US satellites In addition, the Soviets are probably conenned that the US will eventually develop space weapon systems.

In any event, we believe that the Soviets would prefer toystem which could track foreign satellites more accurately and permit the me ol non-nuclear kill mechanismi.11

An antisatellite system employing these radars could use an existing missileudear warhead. Non-nuclear kill, on the other hand, wouldoming missile capable of eioatmospheric maneuver which could be developed in about two yearsecision to do so. Although we have no evidence of such devdopmcnt. it could be well under way without our knowledge. We believe, therefore, that at about the time the Hen Houses become operational the Soviets could have an antisatellite capability with either nuclear or non-nuclear kill Wo consider the latter more likdy because the capabilities of the Hen House radars appear to exceed that requireduclear kill.

On the basis of the foregoing considerations, we estimate that the Soviets will bave an oraerational antisatellite capabilityophisticated system

ilitary control of Soviet civil defense has increased steadilyhen the program was shifted lo the Ministry of Defense. The ranks of the military officers assigned to civil defense staffs have also been upgraded, and the cuient head of the programarshaleputy Minister of Defense. During the same period, the Soviets have continued to implement compulsory training courses for the general public; we estimate that as many as ono hundred million Soviets have been exposed to instruction, and that many have been highly trained in basic civil defense procedures. In thea training, the Soviets have been emphasizing ways to conduct strategic urban evacuation andfAr homemade fallout shelters. They have abo created mobile units, or rescue columns, to provide post-attack assistance both in urban and rural areas. The effectiveness of these procedures depends on strategic warning. apathy on the part of the public has tended to reduce ihe plannedof this training.

e calculate that there are aboutillion fallout shelter spaces available for the urban population, or roughly one space for every five dtydwellers. Most of these shelters were built riuring, when new public buildings and apartment houses were constructed with special basements for civil defense purposes. Since thehe Sovieti have severely curtailed their urban shelter construction program, and we have no evidence to indicate that Ihey areesumptionajor shelter construction program They have,probably made some provisiorss for including shelters in certain publicnow under construction. In view of the program's emphasis on urbanand rural self-reliance, we believe that tho Soviei leadership does not expect the present civil defense program to provide significant protection for moremall portion of tbe population. Although the Soviets might during the decado resume Uxge-aeaue shelter construction, we think that other demands of Soviet resources, particularly those for advanced weapon systems, will preventevelopment.

" Mr. Thomas L. Hughes, the Director of Inrelllgenoe and Research. Department of State, bclievea that thewoold conclude that the adverse cemaeaucaec* of destroying or damaging US latdLtci tn peacetime would outweigh ihr advantagra of pjch an action. He therefore believes rt highly unlikely that they would attack US satellites la peacetime.
