SOVIET STRATEGIC DEFENSES

PRECIS

Over the past year, Soviet strategic defenses have evolved generally as estimated in, and new evidence does not require thai any of the basic judgments be changed.

The Soviotsumber of major programs underway which arc designed to upgrade their existing strategic air defenses. Porthc range of theystem has been increased. Theyconsider that continuing improvement of existing air defense systems represents the most economical way to enhance their strategic defensive capabilities over the next five years or so.

For the last several years, there have been no new strategic fighter interceptors or surface-to-air missile (SAM) systems under flight test at any of the various research and development) ranges and testsituation which is unique in the post-World War II period. We do not believe, however, that strategic air defense is being downgraded. Rather, it may be that, over the longer term, the Soviets will await more fundamental changes based on new technology, suchook-down, shoot-down system, or different physical phenomena, such as an air defense laser, before undertaking any deployment of new systems.

The pace of Soviet antiballistic missileontinues unabated since the signing of the ABM Treaty. The most significant new development has been the appearance at the Sary Shagan ABM test centerew conical-shaped missile. Indicating the Soviets may now be developing the projected system to intercept reentry vehicles (RVs) within the atmosphere alter exoatmosphericaids have been stripped away. However, it probably will not have an acceleration comparable to that of the US Sprint and has yet to be flight tested.

There.continues to be no evidence of Soviet expansion of ABMat Moscow or construction of intercontinental ballistic missile (ICBM) defenses as penrutted by the Treaty, bulto complete the ballistic missile early warning radar network around the European USSR.

We have detected no significant advances in Soviet antisubmarine warfare (ASW) capabilities which increase the threat to the USmissile launching nuclear submarine force, althoughwork on new techniques is clearly being intensively pursued. Tbe most modem Soviet nuclear submarines are still far noisier than those of the US. As noted in. the Soviets continue toonsiderable and vigorous research effort in the area ofdetection by utilizing nonacoustic phenomona. In this area our information onontinues to be limited, and ourare great. However, none of the currently better understood nonacoustic detection techniques appear toasic solution to finding US ballistic missile submarines in the openhe Soviets

.

Since (lit publication ol, Soviet effort! to improve their strategic defenses have continued essentially as expected.orms tioo has been obtained In tho fields of air defense, ballistic missile defense, and strategic ASW which adds to our understanding of these elements. On the other hand, there It no new evidence which Inaeases. oor grasp of theand scope of Soviet anttjateuito or civil defense activity. None of the new Information, or lack thereof, bas altered the basic judgments of the Estimate nor have any of the dissenting agency views been changed. This Memorandum to Holders review* those recent developments which pertain lo the roa|or judgments In the Ei tun it e. and it assesses their significance.

I. STRATEGIC AIR DEFENSE

hc air threat, as perceived by theis both large and technicallyWhile the bomber forces of the US Strategic Air Command have continued to decline in numbers, developments Incountermeasures, alr-lc-surface missilesnd tactics have tended to increase their ability to penetrate strategic air defenses. In addition, the Soviets are faced with the nuclear threat posed by US tactical aircraft

and missiles stationed In Europe, Asia, and at sea and with the air threat posed by the rest of NATO in the west ind by China to the south. The Soviet effort to counter these threats continues as described in.

Although the overall tlx* of their figbter-interceptor force hu clecresssed, itsagainst air attacks from medium and high altitudes continues to be enhanced. This is being done by making greater use of the latest air defense data transmission systems, by extending litem into new areas, and bythc proportion of modern aircraft in Ihe interceptor inventory. The number of SAM launchers has remained essentially the same as last year.

Although the recent Middle East war showed that the Soviets have improved tactical low-altitude defenses, the weaknesses of the strategic air defenses against low-altitudeand against modern standoff threats such is Ihe US short-range attack nusstle (SRAM) remain. Soviet efforts to overcome thesehave continued, but no fundmental

Atsites, however, four older launchersreplaced by three of the0 percent increase tnWhile It Is too early In the programfirm Judgments regarding thc changeconfiguration, we believe thatpurpose Is to increase the readyof theites.

B. Future Developments

Soviets are developing aradars which could enhance Soviet aircapabilities. The over-the-horizon(OHD) system being built nearbe able to provide early warningattacking from the Faeroes Capsuccessful in this role, the Kiev radarearly warning against alrcraltatltitude several hundred

miles from the Soviet border. At the same time, radars continue to bo developed at theYar Missile Test Center. In one areaew. large aperture, nodding height finder radar (Odd Pair) fcutaOedoot tower. If deployed la this manner, the radars horizon would be considerably ox-tended, and low-altitude aircraft would besooner. Several new. unidentified air surveillance radars are locatedecond area, but their potential role is not known at this lime.

lhe Soviets have had no new strategic fighter-interceptors or SAMs under test fet any of thcanges and test facilities' for severalsituation unique In tbe postwar period. As it usually takes some five years from our first identificationew system until its deployment, this means they probably will sot deploy any new models of aircraft or SAMs developed jpecilicaily for PVO Strany before the.

On the other hand, we haveontinuous cycle of improvements insystems, designed largely to improve performance against the low-altitude bomberotentially significant development involving elements of theystem isat Launch Complex G. Sary Shagan.

^may Indicate that some part of theystem is being modified and optirnixed totargets at greater ranges aod to engage them at lower altitudes. It li also possible thats being used toew strategic SAM, but until it receives more equipment, these activities will remain

n tbe past few years, tbe SovieU have added optical systems to tactically deployed

elevision iystcm ton tho field foices. These electro-optical aids, which can be used to perform some radar functions, counter to some degree the use of electronic count enneasures by attacking aircraft and, in certain cases, permit rnore effectiveof low-altitude targets. Tbc Soviets may also Introduce such systems Into strategic SAM defenses.

li It Is also possible that the SovieU will Integrate SAM systems, normally associated with the field forces, into strategic defenses. Systems such as thendave some capability against low-alo'tudc bombers, and, since they arc mobile, they could complicate US SAM avoidance and suppression tactics. Further, the Soviets could introduce Into PVO Strany new mterceptors based oa tactical fighters such as tbe Flogger, which has been deployed, or rhe Fencer, which is now being tested.

IS. We doubt that the Soviets will deploy, over the neat five years, anywhoUy new air defense weapon systems which provide merely increineutal improvements over presentThey probably consider that continuing improvement of elasting defense systemstlie most economical way to enhance their strategic defensive capabilities. It may be that the Soviets will await morechanges based on new technology, suchook-down, shoot-down system, orphysical phenomena, such as an airlaser, before undertaking anyof new systems. Both could bein the, as indicated In. They probably are working now on componentsaser system, as Indicated In Section VI of this Memorandum.

udgment! regarding Soviel strategic ASW capabilities remain essentially as stated in

n tliii connection, data collected against units of the latest Soviet nuclear submarine,lass. indicate that its noiseare similar to those of otberlass submarines. We believe that if new quieting techniques were available, they would have been used onlass.

lass. Both submarines arc someeet longer than thoir predecessors, but the reason for the increased length has not been determined. It could be for improved sensors, weapons, habitability, or some combination of factors. Preliminary evidence suggests that the noise level ofs about the same as that oflass.las? probablya towable VLF communications buoy.

s important as these developmcnU axe to the general Soviet ASW program, tbey will have little impact upon the Soviet Unions ability lo conduct strategic ASW as long as the open ocean detection problem remainsDuring the past year ihere has been no new Information which indicates anyimprovement in Soviet open ocean detection capabilities by acoustic means. Our information on Soviet research in non-acousb'c detection is extremely limited, and ourare greater than for any other technology discussed in. As wc said in that Estimate, we feel reasonablythat the Sovtcls are mounting aeflort ia thU area. And to the extent that they are successful, the result might be aimproved system for search of the open ocean. However, none of tbe currently better understood methodsasicto the problem of finding US SSBNs in the open ocean. Eveo If the Soviets were to develop improved sensors, there would still remain the problemorpora ting these techniques into an integrated system toan effective counter to the US SSBN force. We believe we would recCfgnize theof new detection systems as well as the development of anti-SSBN forcesthem.

B. Protection of Soviet Ballistic Missile Submarines

here are indications lhat the Sovieu may be showing rnore concern over theof their ballistic missile submarine fleet. At an informal arms control seminar boldS university ineorgly A. Arbatov, Director of the Institute of USA, was most cmpliatic about tlw necessity of ASW limitations io conjunction with otheron strategic armaments. Arbatovparticular concern that Sovietwere forced by geography to negotiate relatively narrow and restricted passages in order to gain access to their open ocean patrol areas. Specifically, ho mentioned the area around Spitsbergen as an example of what tlie SovieU face in this regard.

t Is, of course, not possible towhether Arbatov was presenting official concerns or his own private assessment.the SovieU are undoubtedly aware of our ASW activities io and around egress routes used by their SSBNs. They have made some' attempt to protect their SSBNs through changes in operational procedures andpatterns-

VI. FUTURE STRATEGIC DEFENSES. MILITARY LASER PROGRAMS

ver the past year there haveumber ol Important developments that re-

force previous evidence of major Soviet military-relatedrograms. We have received an increasing number of indications that their high energy laser research effort is expanding.

The types of lasers and the power sources" being developed by the Soviets suggest that these programs are related to the development of laser weapon systems. However, theof laser radars is apparently also among Soviet objectives.

A. Laser Radars

hile laser radars will not replaceradars, their development couldtheumber of attractiveMost laser radar advantages overradars stem from their higher resolution, whichesult of the short laser wavelengths. Laser radars offer the capability for highly accurate measurements of target range, angle, and velocity, with accuracies at least an order of magnitude better than conventional radars. Because of their small angular beamwidths. laser radar beams scattered from targets can

be used to guide horning type weapons to their targets more precisely. Theirinclude lack of an all weather capability and inability to search large volumes of space because of their small beamwidths. Precision tracking conventional radars must be used to provide target acquisition by the laser.

laser radars could be used forantisatellite, and ABMthe. As part of an airthey could be used to illuminateto provide precision tracking and aguido semi-active homing-type missiles.antisatellite role they could provideephemeris data, "photographic"for satellite identification, and alsotooming interceptor to atarget.
