The Estimate docs not consider all the systems which the Soviets regard as strategic. It does not cover in detail all the Soviet medium-arid intermediate-range nuclear delivery systems, which arc intended mainly for operations on the Eurasian periphery. Nor does thc Estimate treat Soviet objectives and policies governing the use of all elements of national power toward thc attainment of overall strategic goals. For

In estimating Soviet objectives, policies, and programs, we have assumed that future United States forces will be as described in the Department of Defense, Five-Year Defense Programhich includes US programs for such strategic systems as the Trident ballistic missile submarine,omber, the improved Minuteman HI missile,CBM. and advanced cruise missiles. Wc have made this assumption in the belief that US programed forces probably comprise the minimum future US inventory of forces for intercontinental conflict against which the Soviets plan and evaluate their own programs. Our forecast of thc strategic environment does not attempt lo weigh the implications of increases or decreases in programed levels of US effort or of alternative US decisions about specific weapon systems.

In order to judge the future overall effectiveness or all Soviet forces for inlerconlinenlalas well asdetailed net assessment is required which pays particular attention to operational factors and to the way in which the full range of US and Soviet forces and capabilities might interact. We have not madeet assessment.

KEY JUDGMENTS CURRENT DEVELOPMENTS IN SOVIET PROGRAMS

In offensive forces for intercontinental conflict, the Soviets arc continuing their long-term effort to acquire more powerful, flexible, and survivablc weapon systems.

intercontinental ballistic missiles (ICBMs) are being deployedoderate pace.ow are operational, most of them with multiple independently targetabie reentry vehiclesnd there will probably be morehese missiles have belter accuracy, greater throw weight, and more survivable silos than their predecessors. Deploymenland-mobile ICBM is apparently still deferred

Several unitsew version of the Soviets' latest class of nuclear-powered ballistic missile submarine (SSBN) have been launched. They will probably carry the first Soviet submarine-launched ballistic missile (SLBM) to be equipped withew. large ballistic missile submarine may be under construction. If so, it could be operational by

Improvements in ICBMs and SLBMs will not slop with tin-current missiles The Soviets areumber of new and modified ICBMs and

iThcsc systems will incorporate qualitative improvements, probably including still better

Backfire bomber continurs lo be deployed. Theie are uncertainties and differences of view within the Intelligence Community about the extent of the Backfire's capability for intercontinental operations and about Soviet intentions to employ it in (his role. We have additional evidence this year pointing to Soviet development ofa new long-range bomberew aerial tanker.

The Sovicls arr also pressing ahead wiih efforts lo improve their strategic defenses.

l,argc new radars under consliuction in the northwestern USSR will improve and extend Soviet ballistic missile early warning capabilities when they become operational inhere are uncertainties and differences of view in the Intelligence Community about whether these radars will also be given capabilities to direct and manage antiballistic missile (ABM) defenses. The Soviets continue their research and development on ABM systems.

A number of programs are aimed at remedying thc critical deficiencies in Soviet defenses against low-altitude air attack. The Sovicls have been deploying data-handling systems and are introducing an improved fighter into strategic air defense forces. New air defenseew low-altilude surfacc-to-air missile (SAM) system,ew fighter with better low-altitude intercept capabilities arc under development and could be operational by

Soviet forces for antisubmarine warfare (ASW) are improving but are not now an effective counter to US SSBNs. The Soviets continue to investigate both acoustic and nonacousticin an effort to solve Iheir fundamental problem of detecting and tracking SSBNs at sea.

The Soviets have this yearapability to attack satellites at low to medium altitudesore timely manner.

Soviet civil defense preparations are steadily improving. This program is more extensive and better developed than we had previously understood, Thc Sovicls also continue to harden facilities associated with strategic forces.

The Soviets arc conducting research and development which could lead to dircctcd-energy weapons having important applications in strategic defense. The Assistant Chief of Staff. Intelligence, Department of the Air Force, belieoes that this effortarge and well-funded program toharged-particte-beam weapon.

SOVIET OBJECTIVES AND EXPECTATIONS

The growth of Soviet capabilities for inlerconlinental conflict over thc past decade has provided the USSRowerful deterrent and

oe9fShPe/t

has contributed to its recognitionuperpower equal to the US. An

assessment of Ihe perceptions and objectives underlying present Soviet programsatter of interpretation and considerable uncertainty. Much that we observe can be attributedombination of defensive prudence, superpower compelitivem-ss. worst-case assumptions about USilitary doctrine which stresses war-fighting capabilities,ariety of internal polilical and institutional factors. But the continuing persistence and vigor of Soviet programs give rise lo the question of whether the Soviet leaders now hold as an operative, practical objeclive thc achievement of cleat strategic superiority over tlic US during the period of this Estimate.

The Soviets' belief in the evenhial supremacy of their system is strong. They see iheir forces for Intercontinental conflict as contributing to their ultimate goal ofominant position over the West, particularly the United States, in teims of political, economic, social, and military slrength. Having come this far in strategic arms competition with lhe US, the Soviets may be optimistic about their long-term prospects in this competiiion. But ihey cannot be certain ilwut future US behavior or aboul their own fuiure strategic capabilities relative to those of lhe US They have seen US lechnology and industry mobilized to grcnl effect ln the past and are concerned about current US force modernization programs. Thus, ihey probably cannot today set practical policy objectives in terms of some specific relationship between iheir intercontinental capabilities and those of thc US. to be achievedpecific period of time.

We do noi believe that the Soviet leadeis presently countcombination of actions by the USSB and lack of action by tbe US which would give them, in lhc nextapabilily for intercontinental conflict so effective that the USSR could devastate the US while preventing the US from devastating lhc USSR. Soviet expectations, however, clearly reach wellapabilily that merely confines to be sufficient to deler an all-out attack.

In our view, the Soviets aie striving to achieve war-fighting and wur-survival capabilities which would leave lhe USSRetter position ihan the US if war occurred The Soviets also aim for intercontinental forces which have visible and therefore politically useful advantages over lhe US. They hope that their capabilities for intercontinental conflict will give ihem more latitude ihan they have had in the past for (he vigorous pursuit nf foreign policy objectives, and that these capabilities will discourage the US and others Irom using force ot lhe threat of force to influence Soviet actions

The Director, Bureau of Intelligence and Research. Department of State, agrees with the statement above on the ultimate Soviet goal but believes the Soviet leaders have more modest expectations for tlieir strategic programs. He uxiuld emphasize that the Soviet leaden

that the US need not concede the USSR any meaningful strategic advantage and do not expect the US to do to, whatever their assessment of present US resolve might be: and

not entertain,ractical objective in thc foreseeable fuiure, the achievement of what could reasonably beas a war-wlnning" or "war-survivor posture.

Rather, in his view, Soviet strategic weapon programs are pragmatic in nature and are guided by more proximate foreign policy goals. He sees the Soviets undertaking vigorous strategic force improvementsiew to achieving incremental advantages where possible but, above all, to avoid falling behind lhe UStrategic environment increasingly characterized by qualitativethus losing the position of rough equivalence with the US which ihey have achieved In recent years through great effort. Moreover, he believes il unlikely that the Soviet leaden anticipate any improvement in the USSR's slrategic situationis the US over lhe nexlears which would substantially influence theirtheirfor riskperiods of crisis or confrontation with the West.

The Defense Intelligence Agency, the Energy Research and -Development Administration, thc Assistant Chief of Staff forDepartment of the Army, the Director of Naval Intelligence. Department of thc Navy, and the Assistant Chief of Staff, Intelligence, Department of thc Air Force, believe that the Soviets do. in fact, see as attainable their objective of achieving the capability to wage an intercontinental nuclear war, shouldar occur, and survive il with resources sufficient to dominate the postioar period. Further, these agencies believe lhal this objective servesractical guideline for Soviet strategic force development even though the Soviets have not necessarilypecific date for its achievement. In their view:

Soviel programs for improving forces for intercontinental conflict (including those for strategic lutrdening and civilheir extensive research on advanced iveaponsand their resource allocation prioriucs are in keeping with this objective and illustrate its practical effect.

combination with other military and nonmilitary deoelop-ments, the buildup of intercontinental nuclear capabilities is integralrogramed Soviet effort to achieve tlie ultimate goalominant position in the world.

it cannot be said until confidence when the Sooiets believe they will achieve this goal, they expect to move closer lo it over the nextears and.esult, to be able increasingly to deter US initiatives and to inhibit US opposition to Soviet initxatiws.

The Assistant Chief of Staff, Intelligence, Department of the Air Force, further believes that this Estimate understates, as have previous NIEs, the Soviet drive for strategic superiority. The lines of Soviet strategic policy, objectives, and doctrines enunciatedarge body of authoritative literature ore viewed within tlie context of differing US perceptions and aspirations rather tlian in the larger context of Soviet history, ideology, and military investmetit.

The Soviets have made great strides toward achieving general military superiority over all perceived constellations of enemies and forcar-winning capability at all levels of conflict. War survival and civil defense efforts to date have already placed the VSosition of serious strategic disadvantage by neutralizing much of its capability to destroy or damage effectively those elements of the Soviet leadership, command, military, and urban-industrial structure required forredible deterrentealistic calculation of nuclear fatality exchange ratiosar today would probably show the USSH emerging with considerably morewentymo-one advantage.

Tliere nowubstantial basis for judging that the Soviets' negotiations at SALT and their detente, economic, and arms-control diplomacy have thus far been exploited by them for strategic advantage: by slowing down US defense investment and by permitting easy access to high US technology. Thc net effect of improved Soviel and Easi European access to loans, goods, and services from many Western countries is that inefficient sectors of the Soviet economy are in effect being subsidized, thus encouraging uninterrupted investment in strategicegree of hostage control is being acquired over elements of thc West European banking structure by Moscow and Us East Europeanthe form of extensive loans [now approaching allowable limits for manylias serious economic warfare implications. Additionally, tlie extraordinary advances being made by the Soviets in ASW and high-energy particle-beam technology could

5

place the Free World's offensioe ballistic missile capability at serious risk well before the terminal date of this Estimate.

While the present NIE is much improved over some of its predecessor documents, it falls far short of grasping the essential realities of Soviet conflict purpose and evolving capability, the latter clearly constituting the most extensive peacetime war preparations in recordedsituation not unlike that of the. when the entire Free World failed to appreciate the true nqtttre of Nazi Germany's readily discernible preparationsr and conflict. The dissenting judgments of the past five years regarding Soviet defense expenditures, Soviet. strategic objectives and policy, ICHM refire capability, predictions3 that someoajor new or modified offensive ballistic missile systems were under development, Soviet war-survival and civil-defense measures. Backfire bomber capability, and directed^energy weapons development have often served as the principal means of alerting the national leadership to trends which now are clearly evidenced. Failure now to anticipate the implications of such trends will impact adversely on lead times essential for the alteration of policy and redirection of technology programs.

Such lead-time impacts are illustrated dramatically in judgments of the0 which implied tltat Soviet goals entailed tio more than strategic parity and did not involve commitmentajor civil defense program. The Assistant Chief of Staff. Intelligence, Dej>artment of the Air Force, believes that the former was the basis for US arms control policyliile the latter influenced the ABM Treatye is concerned that the present perceptions of Soviet goals and evolving capability provide an inadequate basis for the pursuit of further negotiations at SALT or thc reformulation of national defense and foreign security policy. Al issue is whether present intelligence perceptions provide an adequate basis for averting global conflict in the decades ahead.

TRENDS IN fORCES AND CAPABILITIES

Varying degrees of uncertainly characterize our estimates of Soviet strategic programs and of the quantity and quality of Soviet forces. Forecasts (or the next few years can he made with relatively high confidence on the basis of direct evidence. For the period of primarytoearsof system characteristics and force composition musl be based on very limited evidence and indirect considerations. In this connection, it should be noted lhat uncertainties about lhc quality of stralegic weapons and

rap

preseni nnd particularly for theIn some areas large enoughf feci judgments about Important asjwcls of lhe strategic balance.

Our forecast for the nextears assumes lhat the ABM Treaty remains in effect and lhal US forces will evolve as currently programed We employ commonly used measures of force capabilily bul cannot take full account of operational factors which would affect the actual outcome of an intercontinental conflict. Examples of such factors are lhc efficiency and vulnerability of US and Soviet command and control systems, and the effectiveness of US air attacks and Soviet air defenses in an electronic warfare environment.

Offensive CopobilitiBv

The bulk of Soviet intercontinental striking power will remain In ICBM forces. The striking power and survivability of SLBM forces will continue toelatively small intercontinental Inimber force will be retained to complement lhe ballistic missile forces.

the, the number of Soviet missile reentry vehicles {HVs) will probably approximate and possibly exceed that of the US. The large Soviet advantage in missile throw weighl will be much greater than it is loday, and (lie Soviel advantage in total equivalent mcgalonnage (EMT) will be somewhat greater. Soviet ICBMs will pose an increased threat lo US missile silos; this threat couldajor one In the next year or so if Soviet ICBM capabilities arc at the more threatening bul highly unlikely extremes of our range of uncertainly. Soviet silo-based ICBMs. however, will not be very much mote vulnerable than at present. Despite the probability that the US will continue to have more varied offensive forcesarger total number of weapons, increasing Soviet missile throw weight and numbers of RVs. and the increased threat to US silo-based ICBMs. will add to perceptions of Soviet strategic power.

the, the raw power of Soviet offensive forces will coniinue to increase. Soviet ICBMs willajor threat to US missile silos, although thc Soviets themselves would remain uncertain alxml the results of counlersilo attacks. If US forces develop as now programed and Soviet forces continue to develop along preseni lines, some of the earlier Soviet gains in relative offensive capabilities will be eroded. With tbe deploy-meni of new US systems. Soviel forces would be likely to fall behind in numbers of missile RVs and farther behind in total weapons. In any event, lhe chances that the Soviets could

7

arge lead in missile RVs would he reduced. Their advantage in total EMT would he likely to drop back lo about today's level, but their advantage in missile throw weight would remain very large. The Soviets could judge that their own silo-based missile forces had become very vulnerable.

In lhe licit few years, SLBMs willarger percentage of the total Soviet ICBM and SLBM force, thus increasing the proportion of launcheri which can achieve better survivability through mobility. Although lhe Soviets have evidently deferred deploymentand-mobili' ICBM. they will probablyn such systems and might deploy one toerceived danger to their silo-basedand-mobile intermediate-range ballistic missile (IRBM) now aboul lo be deployed will be difficult for US inlelligence to distinguishimilar land-mobile ICBM and might be convertible Io an ICBM fairly rapidly.

The Sovieis could at any time increase the threat to US bombers on alert by deploying SSBNs close lo US coastlines to reduce the potential warning limes available lo bomber bases. In deciding whether to rely on SLBMs for this purpose, the Sovicls would have to consider US ASW capabilities, US options to reduce the vulnerability of existing bombers, and Iherogram. We believe the Soviets would conclude that, throughout the nextears, most US alert bombers wouldurprise SLBM attack

We believe lhe Soviets have no compelling military reasons to deploy long-range cruise missile systems in the present strategic environment. They evidently believe the USechnological advantage in such systems, but if they cannot prevent US deployment through SALT, they may follow suit They could modify uny one of several existing air- and sea-launched cruise missiles for long-range use or could develop large, new ones for deployment by the end of. Small, long-range cruise missiles accurate enough lo destroy hard laigels probably could not be flight-tested before lhe early to.

Soviet Intercontinental striking power would be increased if Backfire bombers were employed against thc US The Backfire is well suited to operations against land and sea targets on the Eurasian peripheryariety of flight profiles, and it has some capability for operations against the US on high-altitude subsonic profiles. The Defense Intelligence Agency, the Assistant Chief of Staff for Intelligence. Department of the Army, and the Assistant Chief of Staff. Intelligence, Department of the Air Force, estimate that the Backfire has stgntficant capabilities for operations against the US without air-to-

ooaisi-Tti/

Top Stoat*

air refueling. The Central Intelligence Agency and lhe Department of State estimate that it has marginal capabilities against the US under the same conditions. With air-to-air refueling, the Backfire would have considerably increased capability for intercontinental operations, even in the case of the lowest performance estimate. In addition, the Backfire could be modified in various ways to improve its range.

Wc believe it is likely that Backfires will continue to be assigned to theater and naval missionsthc exception of DIA, ERDA, Army, and Airbelieve it is correspondingly unlikely thai they will be assigned to intercontinental missions. If thc Soviets decided to assign any substantial number of Backfires lo missions against thc US. they almost certainly would upgrade lhe performance of the aircraft ororce of compatible new lankers for their suppori. The Defense Intelligence Agency, the Energy Research andAdministration, the Assistant Chief of Staff for Intelligence, Department of the Army, and the Assitant Chief of Staff, Intelligence, Department of the Air Force, believe tlie available evidence on Backfire employment indicates only that peripheral and naval attack are its current primary missions. Since the Soviets could use the Backfire's intercontinental capabilities at their initiative, these agencies believe that the Backfire clearlyhreat to the US. even witliout the deploymentompatible tanker force or the upgrading of the aircraft's performance. The Assistant Chief of Staff, Intelligence, Department of the Air Force, further believesortion of tlie Backfire force will have missions against the contiguous US.

Defensive Capabilities

Thc Sovicls arc continuing to improve their ballistic missile detection and tracking systems lo close gaps in existing coverage, to make warning information more precise, and to provide additional warning time. Wc believe thai two large phased-array radars now under construction in the northern USSH will be used for ballistic missile warning. Radars such as these, however, could also be given thc capability for ABM bat lieis. to provide tracking and prediclion dala to support ABM defenses. The Central Intelligence Agency and the Department of State, basing their judgment on analysis of the individual characteristics, locations, and orientation of tlw.se two radars and on the status of the Soviet ABM research and development program, believe that both radars are intended only for ballistic missile early tiximing. The Defense Intelligence Agency, the Assistant Chief of Staff for Intelligence, Department of the Army, and thc Assistant Chief of Staff, Intelligence. Department of the Air Force, however, believe

9

the available evidence regarding these radars does notonfident judgment about whether they may alto be intended for ABM battle management. Concern aboul (be possible use of tbc large phased-array radars for ABM battle management would Increase if lhc Soviets started to construe! more such radars in locations appropriate for ABM support and if lhe Soviets punned ABM research and development vigorously. The Department of Stale believes lhat the extent to which construction of additional such radars would be cause for concern would also depend on the assessment at the time of the likelihood of Soviet abrogation of tlie ABM Treaty. This assessment, in turn, would depend in large part on the cxlent to which the circumstances which led tlxc Soviets to negotiate thisthus avoid an ABM competition with thechanged. The Assistant Chief of Staff. Intelligence. Department of the Air Force, believes the two radars alone might be able to support significant deployment of ABM defenses In the western and central USSR.

An ABM system which the Soviets have been developing7 is more rapidly deployable than thc current system al Moscow. Thc pace of fllghl testing has been slow over the past two years, but recently lhe interceptor missile was firedive target for the first time. With this interceptor, the system appears to have atimited capability. Recent construction at the test range suggests developmentighinterceptor, which could greatly enhance the system's capability. If development proceeds vigorously, the system could be ready for deployment in one lo three years or so, depending on whether it Includes thc high-acceleration interceptor. This ABM research and development activity probablyedgencertainties about the futute strategic situation. We believe it is highly unlikely that the Soviets now plan to deploy ABM defensesscow.

The USSR will probably not have significantly better defenses against low-altitude air attackor the period beyond that lime, we estimate that:

For defense against low-altitude bombers, improvements in Soviet air defenses will have lhe potential for overcoming many existing technical deficiencies by lhe. Il might be possible for the Soviets to oveicome these deficiencies somewhat earlierery high level of effort If Soviet deployments are at the rates we think probable, bomber penetration of Soviet defenses would be considerably more difficult in thehan it would be loday.

10

-fop 6wwf

defense against short-range attack missiles (SRAMs) in flight, one Soviet SAM system now under development might have some capability. While there are uncertainties about the characteristics of this system, we believe that, if it has any capability against SRAMs. engagements would be at short ranges with low reliability. We believe that thc Soviets will not have an effective defense against the SRAM by the.

defense against low-altitude cruise missiles in flight, current Soviet low-altitude SAMs and future air defense systems would have some capabilities Their effectiveness will depend on their specific characteristics, their numbers, and their deployment patterns. Wc are uncertain about the degree of protection that could be achieved against low-altilude cruise missiles In the, but we believe it would be low. The Assistant Chief of Staff, Intelligence, Department of the Air Force, believes, however, that the Soviet SAM system underdevelopment might have capabilities permitting deployment to provide some limited terminal defense against cruise missiles for approri-maicly half thc estimated target groupings in the USSB tn the.

The combination of US air attack forces will coniinue to be more difficult to defend against than any one of ils elements alone. The air defense problems which the Soviets now face would be complicated even further by US deployment of advanced bombers and cruise missiles US penetration tactics and tbe degradation of defenses by ballistic missile strikes would continue to weigh heavily against the overall effectiveness of Soviet air defenses. Wc cannot, however, assess the full effects of these and other operational factors.

Recent developments point to modest but steady improvement in Soviet ASW systems and continued growth in their numbers. Tbe future effectiveness of Soviet defenses against SSBNs on patrol will depend in targe part on how successful the Soviets are in detecting and tracking SSBNs at sea. Improved US SSBNs and greatly expanded SSBN operating areas will further compound thc Soviet problem. From our understanding of the technologies involved and ofrograms iu thc US and the USSR, we believe that the Soviets have little potential for overcoming SSBN detection and tracking problems in broad ocean areas This judgment must be qualified, however, because of gaps in our knowledge of some technical aspects of potential sensor developments. On the basis of evidence now available, wc believe that Soviet capabilities againsi SSBNs in confined waters will improve during the period of this Estimate, bul that Sovicl ASW capabilities

-Jep Sew*.

will Tall short of being able to prevent most US SSBNs on station from launching their missiles.

Soviet civil defense preparations couldignificant impact on both Soviet mid US assessments of the likely outcomeuclear conflict. Thc Sovieis probably believe thai civil defense measures contribute to giving tbehanceurviveational entity and to beetter position than thc USuclear exchange. The priorities of lhe Soviet program evidently arc: first, to assure the continuity of government by protecting the leadership; second, lo provide for lhc continuity of important economic [unctions and the protection of essential workers; and, last, lo pcotcct lhe nonessential pari of the population.

There are gaps in our knowledge of lhe civil defense program. Our tentative judgment is that, under optimum conditions which included an adequate period of warning and evacuation. Soviet civil defenses would assure survivalarge percentage of the leadership, reduce urban casualtiesmall percentage, ond give (heood chance of sustaining the population with essential supplies. With minimal warning, some key leaders would probably survive, but the urban population would suffer high casualties and the chances of adequately supplying survivors would be poor. The Soviets probably do notighly optimistic view about tbe effectiveness of their present civil defenses. Even under the most favorable conditions, they probably wouldreakdown of the economy and, under the worst conditions, catastrophic human casualties as well.

Our evidence of Soviel civil defense prepaialionontinuing, steady program ratherrash effort. Because of the gaps in our knowledge, however, we cannotonfident estimate of its pace and future effectiveness.

The Deportmenl of State believes thai thc Soviet civil defense program is seen by the Soviet leadership primarilyrudent hedge against the possibility of attackuclear-armed adversary. The Department believes that tliese Soviet civil defense efforts toil! not materially increase Soviet willingness touclear exchange and will not undermine the deterrent value of US strategic attack forces. It further believes that, at the present time, the scope of the civil defense program does not indicate Soviet strategic objectives beyond maintenance of rough equivalence with the US.

Thc Defense Intelligence Agency, the Energy Research and Development Administration, the Assistant Chief of Staff forDepartment of the Army, the Director of Naval Intelligence,

12

Department of the Navy, and the Assistant Chief of Staff, Intelligence, Department of the Ait Force, believe that the impact of Soviet war-survival efforts upon the US-USSR strategic liatance is greater tlian can be inferred from the foregoing discussion of the Soviet civil defense program In their view, the Soviets see their civil and passive defense program as an essential element in the achievement of the capability to wage intercontinental nuclear war. should one occur, and survive with resources sufficient to dominate the postwar period. These agencies believe that this program willefinite and increasing impact on US-USSR strategic balance assessments in the years ahead. Further, they believe the Soviets wilt attempt to enhance their influence, particularly tn the Third World and Europe, by capitalizing on real and perceived improvements in their war-waging capabilities. The Assistant Chief of Staff, Intelligence, Department of the Air Force, further believes that the strategic balance already has been alteredajor way by civil defense and other measures the Soviets have carried out thus far.

OTHER CONSIDERATIONS

Some of thc Soviets' present programs reflect concerns that US programs would affect their own strategic position adversely. Examples arc ICBM silo hardening and the deployment of long-range SLBMs. Wc are uncertain about the implications of others. The mobile IRBM und ICBM programs, for example, would enable thc Soviets to place more of their missiles on launchers less vulnerable to attack. By their continuing efforts lo improve ABM technology, the Sovieis could put themselvesosition to deploy additional ABM defenses if the ABM Treaty were nbrogated. Such programs probably represent Soviet hedges against future US threats as well as deterrents lo US withdrawal from strategic arms limitation agreements. They could also represent efforts to give lhc Soviet leaders the future option to break out of such limitations if they concluded lhat the situation warranted.

A SALT TWO agreemenl based on the Vladivostok accord would confront thc Soviets with difficult choices and tradr-offs between new and existing systems within an aggregate ceiling on delivery vehicles. Il would limil the more extreme possibilities for growih in Soviel missile throw weight and number of missile HVs. In the absenceALT TWO agreement, the Sovieis would probably increase theirdelivery forces moderately; il is possible thai they would increase ihem considerably. They would not. hrrwever. expect quantitative competition alone to aller lhe strategic balance significantly. They have evidently come to recognize that thc strategic environment in lhc

la

ill be most significantly affected by tlie quality of the forces deployed by the two sides. Their progress in this area will be larpely independent ofWO.

Soviet RAD programs arc consistentesire both to avoid dipping behind the US and to gain the lead in the technology of strategic offensive and defensive forces, particularly if US programs falter. We continue to examine closdy Soviet RAD programs and prospects for major advances that might seriously erode US deterrent capabilities. Wc give particular attention to RAD applicable to directed-energy weapons [or use in air and missile defense and to the detection and tracking of US ballistic missile submarines. Thc Soviets arc working actively in both fields, and there are gaps in our knowledge of this work. Thc available evidence, together with our appreciation of ihe physical, engineering, and operational hurdles which must be overcome, leads us to rate as small the chances that the Soviets can sharply alter the slrategic balance through such technological advances in the nextears. Bul Soviet efforts in these fields merit very close watching.

The Assistant Chief of Staff. Intelligence, Department of the Air Force, believes that the Soviets are significantly ahead of the West in the technologies applicable to particle beam-weapons research, and that the Soviets could berototype eharged-porticU-beam system

PROSPECTS FOR IHE STRATEGIC ENVIRONMENT

The long time period of (his Estimate and the gaps in our understanding and information about aspects of Soviet capabilities require that judgments aboul tlic futuie strategic environment be made with varying degrees of certainty. Wc conclude that:

slrenglh of Soviet offensive forces for intercontinenlal attack will coniinue to increase It may be at its greatest relative Io US programed foices in the. In subsequent years, some of thc earlier Soviet gains will be eroded, assuming that US forces develop as now programed and Soviet forces continue to develop along present lines.

Soviet ICBMs will pose an increasing threat to US missile silos.

but Soviet forces will almost certainly remain unable to prevent most US alert bombers and SLBMs at sea from being launched Soviet defenses will almosi certainly remain penetrable by missile and bomber weapons.

u

Soviet forces will be able to inflict massive damage on the US in either initial or retaliatory attacks. It is extremely unlikely that Soviet forces will be able lo prevent massive damage to tlic USSR from initial or retaliatory US attacks.

There are critical uncertainties, however, about the degree to which the Soviets inould be able to reduce human casualties and limit damage to those functions and facilities which the leadership would consider essential to the survival of their society.

He rejects lhe negative notion regarding Soviet defense Industries as "Uss efficient than formerly believed" He also believes llutt the eslent of the economic burden of lhe Soviet defense effort is greater than reflected, because of its physical dimension and because of the economic growth rate and the paucity af consumer goods.

They have high respect for US technological and industrial strength They have seen it moblll/ed to gteal effect in tbe past and are concerned thai current US force moderniration program! could aflect theit own strategic position adversely, Titus, lhc Soviel leaders probably cunnot today set practical policy obteclives in teitm of some specific and immutable posture for their intercontinental forces to be achievedredetermined period of time Their programs almost certainly arc framed and adjusted to hedge against possible futuie developments.

e do not doubt lhat if Ihey thought they could achieve Lt, Ihe Soviets would program now lo attain capabilities for intercontinental nuclear conflict so effective thai lhe USSB could devastate Ihe US while preventing tho US from devastating Ihe USSR Wc do not believe however, that thev presently countombination ul actions by thc USSR and lack ofy Ihe US which would produce such capabilities during (he nextears.

he Defense Inlelligence Agency, the Energy Research and Development Administration, the Assistant Chief of Slaff for Intelligence. Department of lhe Army, tlie Direclor of Naval Intelligence, Department of the Novy. and the Assistant Chief of Staff, Intelligence, Department of the Air Force, believe lhat the foregoing discussion is in error In that it gives the impression tliat lhe Sovieis believe thai ultimate goals cannot serve as practical policy objectives for future force development because they cannot be achieved in some predetermined limeexample,year period of this Estimate. These agencies believe that the Soviets do, in fact, see as attainable their objective of achieving the capability lo wage an intercontinental nuclear war. shouldar occur, and survive ll with resources sufficient to dominate lhe postwar period. Further, these agencies believe that this objective servesractical guideline for Soviet strategic force development, even though the Soviets have not necessarilypecific dale fvr its achievement. In their view:

Soviet programs for .mproving forces forconflict {including those for strategic hardening and civilheir extensive research on advanced weapons technology, and their resource allocation priorities, are In keeping with this objective, illustrate ils practical effect, and are bringing it progressively closer to realization.

In combination wtlh other military and non-military developments, the buildup ofnuclear capabilities is integralrogramed Soviet effort lo achieve the ultimate goalominant position in the world.

While it cannot be said with confidence when the Sovieis believe they will achieve ihis goal, they expect to move closer lo it over the next JO wears and,esult, to be able increasingly to dcler US initiatives and lo inhibit US opposilion to Soviet initiatives.

he Assistant Chief of Slaff. Inlelligence. Department of lhe Air Force, further believes lhaltlmale understates, as have previous SIF.S, the Soviet drive for strategic superiority. The lines of Soviel strategic policy, objectives, and doctrines enunciatedarge body of authorilaUve literature are viewed within the context of differing US

perceptions and aspirations rather tlian In the larger context of Soviel history. Ideology, ond military investment.

he Soviets have made great strides toward achieving general miliiary superiority over allconstellations of enemies and foraiwmcapability al all levels of conflict. War suiili.i/ and civil defense efforts to date have already placed the USosition of serious strategic disadvantage by neutralizing much of thc US capability to destroy or damage effectively those elements of the Soviet leadership, command, military, and urban-Industrial structure required fora credible deterrentealisticof nuclear fatality exchange ratiosar today would probably show the USSR emerging with considerably marewenty-to-one advantage.

2ft There nowubstantial basts forjudging thai the Soviets' negotiations at SALT and their detente, economic, and arms-control diplomacy have thus far been exploited by them for stralegic advantage: by slowing down US defense investment and byeasy access to high US technology. The net effect of improved Soviet and East European access to loans, goods, and services from many Western countries is lliai inefficient sectors of the Sooiet economy are in effect being subsidized, thus encouraginginvestment in strategicegree of hostage control is being acquired over elements of the Wen European banking structure by Moscow and ils East Europeanihe form of extensive hats (now approaching allowable limits for manyhas serious economic warfareAdditionally, the extraordinary advances being made by the Sovieis in ASW and high-energy particle-beam technology could place thc Free World's offensive ballistic missile capability at serious risk well before the terminal date of this Estimate.

Soviet Ballistic Missile Early Warning and Battle Management Radar Coverage

NOTES

-fop Seed-

-fop.

Wc believeboth lhc new radars will improve Soviet ballistic missile early warningand coverage and that they will be used in ihis role. Large phased-array radars such as these, however, could be given the capability for ABM bailiethe capability to provide tracking and prediction dataupport thc operation of ABM systems. For such radars to perform this role, they would need lo have appropriate signal character-Islics. lo be operated in an appropriate way. and to be equipped with suilable computer hardware and software as well as data transmission systems!"

]

If radars al these locationsattle management role, tbey would noi significantlylhe baltle management support alreadyto the Moscow ABM syslem by eiisting tadars. Assumlngole, they could provide support for limited deployment of additional ABM defenses in the western and central USSB Additional battle management radars would be required lo support widespread ABM deploy men! in these areas. Battle management radars could constitute the long-lead-time elements of an ABM syilern like theow under development al Sary Shagan (secB7

There are differences of view within the Inlelligence Community about the likelihood lhal the radars now under construction will have capabilities for ABM baltle management tittd aboul thc likelihood that the Soviets ate building them Inr use In this role. Concern about the possible use of latge. phased-array radars for bailie management would increase if the Soviets started lo construct more such radars in locations appropriate for ABM support, and if the Soviets pursued ABM research and development vigorously.

Central Intelligence Agency beheoesini^nt. physicalorientations of thru two new radari requirehe eoniideied separately. CIA believes thatof lite new Otentgortk radar was dictated byuse with the Hen House radar at thisIn CIA's view, lhe combined capabilitiesnew radar and the Hen House will noi makefor an ABM battle management role, because

the Hen House is highly susceptible to nuclear blackout and thus cannot be defended by nuclear-armed ABMs CIA docs not believe the Sovieis would base an ABM defensealllt management radar which Is not itself dcfcndabU.

The Central Intelligence Agency furtherihai lhe design of the PechoraIsdictatedequirement to operate autonomously, perfonnlng boih search and tracking functions. Tlwre is no Hen House al this location. The new radar it oriented lo view US ICBMs launched toward the central USSR, and thus wilt provide early (turning to areas, which are not now provided such Information. Although the Pechora radar might have ABM bailie managemeni capabilities, lit location and orientation are not suitable for supporting ABM systems In lhe western USSR, and defense of the central USSR is probably not as high in Soviet priorities.

TrSc Central Intelligence Agency therefore believes thai the new radars are only for ballistic missile early warning. Moreover, CIA doubts that tlie Soviets will lutve an ABM system worth deploying againsi the US threal In the foreseeable future. Nevertheless, further deployment of Pechora-type radars in locations appropriate for supporting ABM defense would be of major concern.

The Deportmenl of State generally supports the CIA assessment of the role and capabilities of these rodan. The Department believes, however, thai the extent to which construction of additional such radars would be cause for concern would depend not only on ihetr locations but also on lhe assessment al lhal time of the likelihood of Soviet abrogation of the ABM Treaty. This assessment. In turn, would depend In large part on the estent to which tlie circumstances which led lhe SovieU to negotiate thisthus aoo'd an ABM competition with thechanged.

The Defense Intelligence Agency, the Assistant Chief of Slaff for Intelligence, Department of the Army, and the Assistant Chief of Slaff. Intelligence, Department of the Air Force, agree lhal the radars ot Pechora and Otenegonk will be used to provide BMEW.

Electronic Warfare

During thc past year we learned that aboul half of fhe ground-based Jamming equipment in lhe USSR belongs to Soviet strategic air defense forces. Previously wc had believed that this equipment belonged to the Soviet ground forces. These jammers probably would be used against terrain avoidance radars and bombing and navigation equipment. The overall effectiveness of Soviet defensive- jamming would dependumber of factors, however, such as weather, thc number and location of jammers, bomber penetration tactics, US electronic counter-counter measuresnd Improvements in US bomber forces.

The Soviels are aware of the degradation which jamming by enemy forces can have on their own ait defense systems, and they haveariety of ECCM measures to minimize the effects of such Jamming. In view of thc many uncertainties, wc are unable loonfident Judgment about (he effectiveness of Soviet ECCM. Such evidence as we have suggests that, in thc aggregate, current Soviet ECCM would not be successful in offsetting (he effects of US electronic countcnncasurcs (ECM).

If Soviet deployments arcrales wc think probable, bomber jwnetrationdefenses would be considerably morelhchan it would be today.

The only Sovicl defensive system which might be able to engage the SRAM is the new SAM under development. While there are uncertainties about the characteristics of the new system, wc believe lhal. if it has any capability against the SRAM, engagements would be at shod tanges with low tcliabiliiy. VVC therefore believe that thc Soviets wilt not have an cffcclivc defense againsi thc SRAM by thcnd will have to seek lo atlack SHAM carriers prior to missile launch.

For defense against low-altitude cruise missiles, current low-altitude SAM syslcms might have some capabilities at short ranges. Fuiure Soviel air defenseAWACS. interceptors, and SAMs-will have some capabllilics against lo*-allilude cruise missiles in flight. Their effectiveness would depend upon their specific characteristics, their

Inielligence, Department of the Air Force, believe, however, lhat lhe combination of characteristics and numbers ol Soviet defensive systems will belo provide prelection fot moremall proportion of the target base.

IIS. The combination of US air atlack forces will coniinue lo be more difficult to defend against than any one of its elements alone. The air defense problems which Ihe Soviets now face would be complicated even further by US deployment of advanced bombers and cruise missiles. US penelralion laclics and thc degradation of defenses by ballistic missile strikes would continue lo weigh heavily against Ihe overall effectiveness of Soviet air defenses. We cannot, however, assess the full effects of these and other operational factors.

Thus, we can make only tentative assessments of how effective that program would be under wartime conditions It Is out tentative' judgment lhal. undet optimum conditions which included an adequate period of warning andSoviet civs! defenses would assure survivalarge petcenlage of the leadership, would tcduce prompt casualties among Ihe urban populationmall percentage, and would give theood chance of bring able to sustain the population with essential supplies.

Nevcitheless. if ihey were to decide to attack the US In peacetime circumslances, we believe that Ihey could minimize indications of their intent by limiting their initial strike forces lo ICBMs and to those Sl.BMs within range of their largcli Preparations could be com-pleled within several hours aflei lhe decision lo Strike had been promulgated. Under ihese circumstances, there would be few indications and liltle lime for analysis upon which US warning staffs could reach andonfident judgment thai the Soviets were aboul lo strike.

V. FUTURE FORCES ANO THEIR IMPLICATIONS

A. Future Force Projections

n projecting lhe sire, characteristics, and mil of Soviel form for inlriconllnenlal conflict, we face varying degrees of uncertainty

In projecting Soviet force levels and mixes for the near termhe neat Iwo yean ore rely rnosl heavily on observed activiiy; wc have relatively high confidence In these near-term estimates.

We aie less certain about force levels and mites for Ihe midterm (about (wo to five yearsut can srill project wllh some confidence because Soviel force* will consist mostly of systems ahead) deployed or in testing.

Large uncertainties pervade our protections of force levels and miaes for the longer term (llie period from five loearsecause we almost never have direct evidence on Soviet long-range planning Our long-term projections are based partly on indlicct evidence and some insights into the Soviet research andprocess nnd partly on our assessment of overall Soviet objectives, technological prospects, and priorities.

arc also uncertainties in estimating thc char act eristics of individual weapon systems, even for the present and near leim, in part because the Soviets go to considerable lengths lo deny us Information on system characteristics.

Alternative Force Projections

ISO. In view of thc variety of deployed forces potentially availablee project five alternative forces to Illustrate the range of capabilities which the Sovieis might develop and deploy under differing circumstances;

Best-SAL) represents our best projection of Soviet strategic force developmentsALT TWO agreement based on thc Vladivostok accord Is leached and Soviel programs continue at the approximate levels of effort andachievement demonstrated in the recent past.

Moderate-No-SAL) illustrates generally similar levels of effort and achievement, butALT TWO limitation.

High-SAL)igh level of Soviet effort and technological achievementALT TWO limitation.

High-No-SAL)imilarly high level of effort and achievement, but without SALT TWO limitations.

Low-SAL)ow level of effort and achievemenl within SALT TWO con-si rain ts.

ISI We corisidei both thc high forces to lie upper-boundary cases and, thus, highly unlikely, because lhe Soviets probably could no! sustain such high levels of effort and achieve such consislantly highsuccess on all fronts simultaneously through theyear period. The low force Is considered an equally unlikely boundary case. Tlse projections, summarized in Table V, are discussed in dclail inhapter V. and tabulated in tolo in Volume III, Anne* A. They encompass both intcicon-tincnlal atiack and strategic defense furces. We do noi include projections of Soviet nnti-SSBN ASW forces because of the difficulty in separating ASW from general purpose naval forces.

Il should be nolcd lhat wc assume Soviet planners would be concerned about the possibility of US two-RV atlacks in lhe fuiure.

Effects of Uncertainty

s indicated above, we ate uncertain of Soviet capabilities against US slfos and of Ihe extent to which Soviet silos couldS ICBM altack. Thc Soviets face similar, but probably somewhat less, uttcertainly. They will reduce their uncertainties aboul the actual CEPs of iheir own missiles through furthernd operational (eating. Nevertheless, this will nut eliminate (lie problems Sovicl planners would have lo contend wllh in attempting to plan an attack againsi US silos. Among other things, the variations in operational performance likely to occurarge-scale attack, especially if multlple-RV ladies ate employed, would lead to considerable Soviel uncerlainly about lhe resultslrlke against the Minuteman force. Soviet planner* would also have fo consider the possibility lhal Ihe US would launch ill ICBMs prior to the impact of Soviet RVj.

Another such program is the ABM system on which testing has recently resumed This syslem can be deployod more rapidly than (he Moscow syslem. although widespread deployment would take several years. By continuing to improve technology related to this syslem, the Soviet) could put themselvesosilion to deploy additional ABM defenses in the even! the AIIM Treaty ii abrogaled Such prog)ami probably constitute Soviet hedges against possible future US threats ai well at deterrents lo US withdrawal from stralegic arms limitation agreements.

The stiategk environmentears hence will be affected importantly by Soviet decisions about how lo respond lo perceived US challenges, by lhe negotiated limitation) on strategic arms lhe Soviet leadership li willing to accept, and by the degree of success thestablishment achieves in pursuing advanced technology applicable to itiatcgic forces.
