To estimate the scale and nature of the Sino-Soviet Bloc air defense system, and probable trends in its capabilities through


Air Defense Policy

he Soviet leaders recognize that an effective air defense system is anelement of the strong military posture which they wish to maintain, both toto the security of the Bloc and to support their foreign policies. The scale of effort presently being applied to the continuing improvement andof the Soviet air defense system is indicative of the high priority assigned to this mission.

he air defenses of the Sino-Soviet Bloc arc designed prirnarily to provide defense in depth for major population, industrial, and military centers,those in the USSR They alsoa barrier around much of the Bloc's periphery. In order to attain maximum effectiveness, all Soviet forces deployed for the atr defense of the USSR arc under the operaUonal controlingle major command. In addiUon to forces directly assigned, other Soviet forces which can

contribute to thc air defense mission are also operaUonally available to thisSimilarly, the air defense forces of other Bloc nations are closelywith the Soviet system.

Recent Developmentshe Soviet air defense system isa major transition which isImproving its capabilities against medium and high alUtude air attack. The principal aspects of this transition are: (a) the rapid installation of surface-to-air missile sites, and (b) thedeployment of an air defensesystem with semiautomatic features. Other significant recent developmentsthe advent of radars with better detection and hdght-nriding capabilities, the introduction of limited numbers of improved interceptors, the estimated in-troducUon of nuclear warheads intomissiles, and the probableof more advanced electronic gear and armament into interceptors.


hc USSR has been acquiringajorecond generation surface-to-air missile systemesigned for defense against aircraft at medium and high altitudes.ites, each with six launchers, have been identified at twoin East Germany, at muscow, miu at many olher locations in thc USSR, most of them in the western part of the country. Defenses of various densities are apparently programmed for major Soviet cities and other key targets, and possibly for certain border areas.the length of time the program has probably been underway, the relative ease with which sites can be installed, and the observed patterns of deployment, we estimate thatites are now in operational status or beingat nearlyoviet urban areas as well as at other targets.

The new air defense control system is now widely deployed in the western USSR and will probably becomethroughout thc country and in Eastern Europe within thc next few years. This system, which provides high-speed communicationsigh degree of reliability and semiautomatic control of interceptors, should overcome most of the deficiencies of the earlier manual system. It willarked effect in reducing reaction time and vulnerability toincreasing information handling capacity, and improving coordination within the air defense system.

loc air defense needs arc served by large quantities of other0 antiaircraft guns and0 Jet fighters. The USSR itself has0 of these fighters, of whichave air defense as

their primary mission. Some Soviet fighters arc probably now equipped with air-to-air missiles. Onlyf the Soviet fighters are all-weather or limited all-weather types, however.adar sitesirtually continuous early warning network aroundoc's periphery and overlapping coverage in many interior areas.

Future Trends

Soviet planners must recognize that the great destructive power of nuclear weapons requires that the defense achieve the closest possible approximationomplete denial of access to vital targets. They will expect manned bombers toa major element of Uie West'sfor nuclear attack over the next five years, but their air defense problems will be complicated by the increasing numbers of Western ballistic missiles.

To meet the manned bomber threat, the Soviet leaders contemplate heavilyreliance on missiles for airTheir comprehensive defensecombining fighters and surface-to-air missiles, is probably designed tomaximum opportunity for successive attacks on penetrating delivery vehicles from the Soviet borders to critical target areas in thc interior. Judging by recentasic program forefenses,ites deployed at

It could probably be widely deployedupplement to existing defenses2s the period advances, Uie USSR will probably strive also to increase its capabilities against advanced bombers and cruise-type missiles.

Early warning ranges and reaction times will continue to permit defense forces to be brought to bear againstdelivery vehicles. For defense of targets on the periphery of Uie Bloc against supersonic Western aircraft and cruise-type missiles, however, warning times will be marginal for Uie effective employment of fighter interceptors. Warning requirements for surface-to-air missiles will probably not be so stringent. As improved communications and control equipment becomes more widespread, the saturation point of thc air defense system will be considerably raised.

The further development of tlieto cope more effectivelyanned bomber threat suggests that they expect to be concerned with this threat at least through the period of this estimate.

In order to attain maximum effectiveness of air defense capabilities, all Soviet forcesfor air defense of the USSR are under the operational controlingle majorSome of these forces are assignedto this command. Other Soviet forces capable of contributing to the air defenseare also operationally available to this command for augmentation of its own forces. Bloc air defense forces are closely coordinated with the Soviet air defense system In order to provide greater defense in depth for keyadministrative, industrial, and military centers.

Thc organization primarily responsible for active air defense of the USSR is the Airof the Country (PVOhich combines ground, air, and naval elementsa headquarters which is administratively equal to those of the ground, air. and naval forces.

Fighter Aircraft

There has been little change ln theof Bloc fighter forces over the past two years. The Soviet fighter force still consists primarily of day fighters: the obsolescent FAGOT, five versions of the subsonic FRESCO, and three versions of the transonic FARMER. Introduction of the FLASHLIGHT all-weather interceptor and of modified day fighters with limited all-weather"D" and "E" and FARMERproceededelatively alow pace.f the force still consists of gun-armed interceptors equipped with optical fire control systems, which are restricted to pursuitunder conditions of good visibility.all-weather fighters arc likewise limited lo pursuit attacks. There is good evidence that two new supersonic fighters are now being introduced into Soviet units.

Theoretically, maximumcoverage of Soviet GCI radars couldup to0 feet with the TOKEN, and up to aneet with the BAB LOCK/STONE CAKE or CROSS OUT/ STONE CAKE combinations. Underconditions these theoretical maximums would not be attained. However, the height coverage capabilities of Soviet radars will probably not be the limiting factor in Soviet GCI capabilities during the period of this

In general, the low altitude effectiveness of Soviet early warning and GCI radars is limited, although some operational radars are nowto have moving target indicators. The development of high frequency ionospheric back-scatter radars which could be used for detection of ICBM launchings has been within Soviet capabilities for at least five years, and some such radars may now be in position.

he most important advance in Soviet air defense communications over thc last few years has been the development and deploy-


ew air defense control system with some semiautomatic features, including data-handling equipment for rapid processing of air defense information and data-linkfor vectoring interceptors. This system, which is similar in concept to the US SAGE system, but less complex, is now believed to be widely deployed in the western USSR and will probably become operational throughout the USSR and Eastern Europe within the next few years. It is expected that data-handling equipment will increase the traffic capacity of each Soviet radar reporting site to at leastimultaneous tracks, and that, when the system is fully implemented, this couldracks. Fighter control centers in the system probably are designed to handlentercepts simultaneously, but we believe the present capability is lessy the end of the period of this estimate, tho full design capability of the system may be' realized. This system, which providescommunicationsigh degree of reliability and accurate semiautomaticof interceptors, should overcome most of the deficiencies of the present manual system. It willarked effect in reducingtime and vulnerability to saturation, Increasing Information handling capacity, and improving coordination within the Soviet air defense system.

lectronic Countermeasures. At present, the USSRapability for jammingbombing and navigational radars atup0 megacycles and possibly higher, and especially for jamming the lower frequencies normally used in Western long range radio communications. Shipboard and ground jamming equipment for useand blind bombing radar ls known to exist. In addition, some FRESCO "D" interceptors with large belly protrusions are believed to carryand spot noise jammer, but this equipment docs not seem to be widely used. The Soviets are known to have employeddeception, including simulation ofnavigational aids, against WesternThey are now producing magnetrons and travelling wave tubes suitable forIn the microwave frequencies, and re-

search in this field is continuing. They are also currently employing passive detection equipment believed capable of detectingfrom the very 'ow frequencies up into the microwave spectrum. Toward the end of the period of this estimate, the USSR willhave in operational use equipmentof jamming at frequencies from0 mc/s. Including all frequencies likely to bc employed by Westernradar, and navigation equipment.

Navigational Aids. Within the last few years, the USSR has extensively improved its interceptor aircraft recovery system bythe elementary two-beacon approach system with installation ofequipment, air surveillance radar,landing systems, and GCA equipment. Although differing In some details, thisis comparable to that used by NATO nations.

More thanercent of this lets! are in Soviet unite Regardingof surface-to-air missiles, we believe that the USSR may now have operational or being em placedites, mostly around main industrial centers, in addition to theites in the complex around Moscow. There is no evidence that anymissiles have been given to any other Bloc nation, and this is not expected to occur until Soviet needs are more fully satisfied.

Generally, the most advanced weapons arc deployed first within the USSR, and in ato make maximum use of theirNew supersonic interceptors, now entering service, have appeared first in units near peripheral urban areas, apparently to provide cover to routes of approach totargets. This deployment is consistent with its best capability as an area defense weapon. The bulk of Soviet all-weather fighters are based in peripheral areas of the USSR andlightly lesser degree around the larger urban centers. Soviet surface-to-air missiles deployed to date are apparently intended primarily for point defense, although the sites seem to be deployed variously, inwith the particular features of each area, in order toaximumto area defense as well. Antiaircraft guns are usually located closer to the defended area than fighters or missiles, and arebi depth, with heavy and medium guns farthest out from the center, and the light AA guns closer in.

The areas of greatest concentration of Bloc air defense weapons and associatedinclude that portion of European USSR from the Kola Peninsula to the Caspian, East Germany, Poland, Czechoslovakia, and the Maritime and Sakhalin areas of thc Soviet

Far East. Heavy defense concentrations arc also found at some specific locations outside these areas, especially In the Urals and inChina. The approaches to Moscow are by far the most heavily defended area of the Bloc. Moscow's defenses include abouturface-to-air missile sites,ay and all-weather fighters, andntiaircraft guns. Although we have no direct evidence, some portion of the surface-to-air missiles probably are armed with nuclear warheads. Moscow's defenses are estimated toigh capability to engage large-scale attacks under all-weather conditions, but probablyvulnerable to very low altitude attack.

eavy prime radars,of tbe TOKEN and BAR LOCK types, andight auxiliary radars areinadar sites in the Sino-Soviet Bloc* These sites are so disposed as to produce virtually continuous overlapping coverage of the periphery.enetrating target by three or more radars can probably be achieved through most of European USSR, the Satellites, and thc Pacific coastal areas. Gaps in peripheral early warning radar coverage now appear only in southwestern China. Radar equipped ships are available to supplement and extend radar cover in maritime border areas of the USSR

The extent of this radar cover isbut its quality varies with thc area to be defended. In well defended areas, the roost solid warning cover exists from0 feet downeet. Height-findingparticularly for altitudes0 feet, depends upon the availability of the newer height-finding equipment, which Is not yet deployed in sufficient numbers to provide dense coverage in all areas. Widerof the new types of radars already in service, together with developments incontrol systems, probably will leadecrease in total radar numbers within the next five years.

Air Facilities

Moreirfields in the Slnc-Soviet Bloc are currently being used for air defense operations. There are, in addition, many other airfields which could be used to support air defense operations and which arelocated in areas consideredfor air defense.

In the USSR, most of the airfields suitable for Jet fighters were developed priorince that date, construction or improvement has continuedore limited scale and has occurred chiefly in the Arctic and otherareas. Despite the considerablein the Arcticacilities are still inadequate for deployment of fighters in the centralxceptew widelybases.

Airfield construction in the Satellites wasigh level during thend has since tapered off. However, aactive program of improvement and construction has been underway in this area during the last two years. Many ofoot runways at military airfields are being lengthenedeet, probably because of the longer runwayof later model and higheraircraft. At both Soviet and Satellite airfields, navigational aids and night lighting equipment appear adequate to support present requirements.

In Communist China, at least seven major airfields have been constructed in the coastal and interior regions during the last two years. In addition, the runways of about eightairfields have been extended and landing aids have been modernized. Atommunist airfields are believed to be equipped with GCA.

Logistic Support ond Mainlenancc

estimate that the Soviet supplytransportation network, and localare adequate to meet immediateneeds in most areas. Antiaircraft

gun and missile installations, airfields, and radar stations are usually located adjacent to populated areas and/or mainand communication lines. Maintenance procedures appear to be exacting andsupervised, and maintenance ofis considered to be good to excellent. Evidence on Soviet electronic equipmentthat it Is generally reliable and well maintained.

Jet Fuel. Although information ison the exact location ol Jet fuel storage points in many areas and the amount of fuel actually stored, operational Bloc fighter bases are believed generally to have sufficient stocks of jet fuelays sustained combat operations. POL storage facilities on many Bloc airfields have been expanded andnow have adequate capacity for Iraining, normal flight operations, and the requiredfor emergency use. There arc nothat training activity has been widely curtailed because of the lack of Jet fuel, although in some instances training appears to have been reduced because of short supplies of jet fuel locally, probably due to transport difficulties.

Jet Serviceability. We estimate that, for present jet fighters, an immediaterate on the order ofercent of unit strength could be achieved without special preparations.0 day stand-down, this rate could bc temporarily Increased to aboutercent for about one week, and then could bc maintained at aboutercent for about another week. Thereafter,rates could bc maintained at aboutercent for approximately six monthscombat conditions, and would then declineercent. Under extreme weather conditions and in areas not served by adequate transportation, such as in the Arctic, the above serviceability rates would be reduced.

Personnel ond Training

The USSR has maintainedighter pilot training schoois wnn an taamaUaiutput ofraduates. Thesewill presumably decline over the next several years with the reduction ln the size of the fighter force. The course of instruction lasts slightly less than three years, during which time each pilot accumulatesours ]et. Very little time Is devoted to night and instrument training during thephase.

Instrument training isin operational units. Night flying has increased considerably and the standards have probably been raised, but we believe they are probably below US standards.

CIVIL DEFENSE Tho Soviet Program

Civil defense in the USSR is supervised by the headquarters of Local Antlair Defense of the Country (MPVOubordinate to the headquarters tn Moscow are MPVO staffs at republic, oblast, city, and rayon levels. These staffs are responsible for planning,supervision, and training, and their members are schooled at an MPVO institute located in Leningrad.

These agencies, supplemented by auxiliary personnel to bring tnem up to strength, are organized as civil defense units for such functions as Are defense, shelter and cover, blackout, and the MPVO staff, line officials of the government hierarchy, such as the oblast MVD chief or thc chairrnan of the city executive committee, function as Ihe responsible civil defense commanders.

Training the Soviet population in civil defense is thc responsibilityaramilitary organization known as DOSAAF (Voluntary Society for Cooperation with the Army,andbout one-fifth of the Soviet adult population Is formally enrolled in this organization. The DOSAAF trainingin some areas has been plagued by an Ui different teaching staff, and apparently by padding of progress reports. DOSAAF aims at training the entire civilian population, with virtually all Soviet citizens between the ages ofndiable for compulsory service with civil defense. The majority of the urban population has been given atortion of the scheduled training, but the general public's participation in alerts and drills has been limited to clearing the streets andwith blackout regulations. Somegroups, such as workers in key factories and students, probably have received more intensive training.

Basement shelters may be available for as many asillion people, whileillion could And refuge in the subways of Moscow and Leningrad. Partially completed subways now exist in Kiev, Tbilisi, and Baku. Basement shelters could provide someagainst fallout, but they are of little use against heavy blast If provided with special doors, subway shelters could provide better protection against fallout as well as against blast and thermal effects. However, there is little evidence to indicate that stocks of food and water have been provided for subway or basement shelters. Heavy bunkers and tunnel-type shelters have been constructed for approximately two million selected persons

the basis of the foregoingconclude that the Soviet air defenseisajor transitionsignificantly Improving Itsmedium and high altitude airprincipal aspects of this transition are:


in weapon systems, thc rapid Installation of surface-to-air missile defenses, andin communications and control, the widespread deployment of an air defense control system with semiautomatic features. Otherdevelopments include the advent of radars with better detection andcapabilities, the introduction of limited numbers of improved interceptors, theIntroduction of nuclear warheads into surface-to-air missiles, and the probableof more advanced electronic gear and armament into interceptors.

Against Subionk Bom ben

The present capabilities of the Soviet air defense system against subsonic bombers would be greatest when penetrations wereln daylight and clear weather atbetweennd0 feet. Under such condiUons, virtually all types of Bloc air defense weapons could bc brought to bear against attacking aircraft. Antiaircraft gun and fighter Interceptwould dimiriish0 feet, although present Soviet fighters could operate with some effectiveness at altitudes ln excess0 feet. At alUtudes beloweet, the capabiliUes of thc system would be progressively reduced; beloweet, thc system would lose most of Its effectiveness.

Because of Uie limited availability of all-weather fighters, Uie capabiliUes of Uie fighter force would be reduced considerably during periods of darkness or poor visibility.In Uie Increasingly widespread areasby surface-to-air missiles, air defense capabiliUes would be unimpaired by visibility or weather conditions and would extend to at0 feet in alUtude. Radar-controlled antiaircraft guns could also engage lnpointed fire under any visibility or weather conditions, within their altitude

Thc principal current weaknesses in Uie Soviet air defense system arc: ils limited all-weather fighter capability; Uie tjafnc-handling capabiliUes of communications and control components, Uie inadequate low altitude tracking capability; deficiencies in fighter

armament; the limited early warning Ume available In Bloc border areas; and the lack of an operational surface-to-air missiledesigned for use against very low altitude attacks.

Againtf Other Delivery Syslomt

Soviet defense capabiliUes against current Western fighter bombers, supersonic bombers, and cruise-type missiles are more difficult to assess, but probably are generally inferior to their capabilities against subsonic bombers. The smaller radar cross-sections of thesevehicles would reduce the Soviet ability to detect them and to give warning toweapons. Assuming successful detecUon and tracking. Interception by fighters could probably be accomplished only by thc limited numbers of transonic and supersonic types now in Soviet units. Surface-to-air missile systems, however, wouldonsiderably greater capability against such vehicles, except at low altitudes.

We believe Uiat Uie Soviets do not now have an active defense capability against ballistic missiles of any type.

(d) the likely Soviet estimate of future trends in Western delivery systems; (e) known and estimated Soviet scientific and technical programs and capabilities to develop more advanced air defense weapons andand (f) the economic resourcesand the considerations we believe the Soviets would take into account In allocating resource: to air defense programs.

Our conviction that active air defense will continue to receive very high priority in the USSR is supported by the history of the Soviet military establishment from the end of World War II until the present. This has been markedonsistently strong emphasis on air defense. The scale of effort currently being applied to modernizing the systemthat this attitude persists. Moreover, the general tenor of the Soviet announcements of0 regarding future military policy pointontinuing high priority for air defense. They also indicate thatcontemplates heavily increasedon missiles to enhance Sovietfor air defense as well as for strategic attack. Finally, it seems certain that the Soviet planners would estimate that the manned bomber threat will continue to be present for at least the period of thisand that in theystem will have to be developed to cope with ballistic missiles.

The deployment patterns of air defense weapons and equipment wilhin the Bloc show that the system Is designed primarily todefense in depth for the majorIndustrial, and military centers of the USSR. Soviet planners will recognize that, while successful defense against sustained high explosive attack could be achieved byigh rate of attrition onforces, defense against high-yield nuclear weapons would require achievementery high assurance of denying access to vital targets. Consequently, they will seek toair defense capabilities to meet each type of Western offensive delivery system, tomajor population and industrial centers by both active and passive means, and totheir own strategic striking forces by

active defense, by concealment, dispersal, or mobility as appropriate, and by hardening in some instances.

Probable Soviel Requirements

On the basis of information wc believe they can acquire, largely through overt means, Soviet planners can probably estimate fairly accurately the numbers, types, and worldwide dispositions of the weapons and deliverythe US and its allies could employ against the Bloc They can probably anticipate,years in advance of operational dates, the weapon systems the West is likely to add to its inventory in future years. However, the Soviets are probably uncertain as to the planned tactics and employment of Western delivery vehicles in the event of general war.

Soviet planners will be aware that, during the next five years, the greatest weight of attack (In megatonnage) that can be launched against the USSR will be In manned bombers, most of them subsonic medium and heavy types. They will expect no increase ln the numbers of subsonic bombers, but they willontinuing improvement inand tactics, especially for low altitude penetration and weapon delivery. The Soviet problem of defense against aircraft will be complicated by the variety'of relatively small bombers and fighter bombers with supersonic capabilities now entering or soon to enter Western inventories.

Present Western capabilities invehicles, comprising aircraft andcruise-type missiles, will begin to change within the next year or two, with the advent of supersonic air-to-surface missiles designed to provide bombers with standoff capabilities up tohe Soviets probably foresee US possession of considerable numbers of such missiles, and must also consider the possible subsequent appearance of air-launched ballistic missiles of. range.

From the Soviet point of view, the surface-to-surface ballistic missile threat will become' progressively greater throughoutime period. Missiles with great diversity

This inventory would include the number required for substitution of theissile for theissile in thearound Moscow. Considering the rate at which we believe deployment has proceeded in the recent past, we estimateasic program ot this magnitude could be completed by thc fall

It Is possibleomewhat greaterofefenses is planned for certain locations and that additional targets will be so defended. Moreover, lt Is likely that mobileystems will be allocated to Soviet forces in theore extensive program,these additional factors into account, might callout ofites and Held force units. If this were tbe case and deployment proceeded at the apparent recent rate, the program could probably be completed some timefissUes were allotted to otherof the Bloc, this program would have to be expanded and might extendfter the current program is completed, we believe that the Soviets will have acquired relatively effective missilefor their major target areas against medium and high altitude air atiack.

Previously, the USSR rolled uponas the prime air defense weapon,in thc single instance of Moscow. We



that tho trend Is now toward aof fighter and missile defenses. These will probably be employed In fairly well-defined zones, in order to effect properbetween fighters and missiles and to provide the defense In depth which the Bloc air defense system alms to achieve. Moscow will remain heavily defended by surface-to-air missiles with coverage out to aboutm. from the center of the city,one beyond primarily for fighter engagement. Elsewhere, surface-to-air missiles will cover key targets, with fighters probably employed in existingn the Urals, Uie Ukraine, and possibly thc southern Maritime region of Uie Soviet Par East, Uie number and conccntraUon of defended locations will create area-typedespite thc limited range of individual missile sites. Likely sea and borderto the USSR will be protected by barriers of advanced day and all-weather fighters, and possibly by surface-to-air missiles as well.

The proportion of fighters in thefighter-missile defense system willIn terms of absolute numbers, wethat05 the total number of Soviet fighters will be reduced sig-nificantly from thc present strength oferhaps by as much asercent. The transfer7 of certain fighter units to PVO control probably indicates Uiat the IA PVO will not decline in strength as rapidly as Uie fighter units of Tactical and Naval Aviation.

As suitable surface-to-air missiles become available inarge proportion of Uie medium and heavy antiaircraft guns willbe phased out of Uie defenses of static targets in Uie USSR Thereery limited amount of evidence Uiatrend hasbegun.

However, in view of the widespread deployment andgrowth potential of theystem, wc now consider it very unlikely that thewill attempt to meet this requirement with an entirely new system ast least in the near term. Rather, technical Improvements will probably be made in the altitude and range capabilities of thcystem. SignificantIn this system could appear ln

Antiballistic Missile System

We do not know what technical approach thc Soviets are employing in what we believe toery high priority program to develop defenses against ballistic missiles. Solution of the problems of an antimissile missile would involve the development of complex and costly components and their integrationeapon system with high capabilities fordetection, identification, discrimination, and interception. The net result would be heavily dependent on tactics, deployment, and the effectiveness of Western countermeasures. Taking these factors Into account, we canonly thatystemould become operational ineriod, and that it would have an undeterminedagainst Western ballistic missiles.

The USSR ls probably also exploringtechniques for active defense against ballistic missiles. We cannot predict the nature or success of such studies. In any case, continuous research and development in antimissile defenses will be underway during the next five years and beyond.

Future Fighter Aircraft

introduction of new fightertypes Into the combinedsystem will continue throughs. In addition, thc Soviets,the period of this estimate, will probably

continue their research and developmenton supersonic fighter aircraft.

To alleviate their all-weather fighterthe Soviets probably will introduceevelopment of FISHPOT with all-weather capabilities. We estimate that2 the Soviets mayew orall-weather interceptoretter performance and fire control system. Thisis based solely on estimated Soviet requirements and technical capability. Such an aircraft could probably achieve speeds up tondombat celling of0 feet. Its airborne intercept radar could probably have search and track ranges ofnd. respectively, aimprovement over the Soviet's best current Al capabilities.

The rate of fighter production andinto units In thes will probably increase somewhat over that of the last year or two, but it will remain low by comparison with earlier years. Older fighters will be gradually phased out of Soviet forces and not replacedne-for-one basis. The primary Soviet effort ln the fighter field will be to improve tbc armament and electronic capabilities of individual interceptors and to perfect techniques for their control and

Air-to-Air Missiles. The Soviet fighter force may be generally equipped with air-to-air missiles.

However, introduction Into service ofissile probably would depend uponuitable nuclear warhead.

The more advanced all-weather fighters may be equipped for completely automatic control of interception. But even for newer fighters on two-minute alert, the total Ume required from detection to engagement wouldbe0 minutes. We thereforethat in areas where radars cannot bc sited well forward of targets and fighter baseslong Blocarning Ume for fighters will be marginal against the highest performance Western aerodynamic vehicles.

The problem of warning Ume for surface-to-air missiles probably will not be soIn Uie usual case, where targethas been made by Uie SPOON RESTin Uie immediate vicinity of Uie SAM site, adequate warning lime is available.of target data could be accomplishederiod of time which would enable the SAM site to prepare to engage the target. We do not have evidence as to Uie method the USSR will use to Ue in Us naUonal early warning network with Its expanding missile defenses. It appears possible Uiat semiautomatic control will be employed for such use as well as the control of fighters.

To the degree that geography will permit, the USSR is extending Its early warningby siting equipment beyond its land borders. The European Satellite area willa valuable forward base for Soviet early warning lines. In the ArcUc. radars have been installed on Islands north of the Soviet coast. In addition, passive detecUon systems inand East European border areas will probably be Integrated Into (he air defense system to counter Jamming and augment thc early warning network. There Is as yet no evidence Uiat the Soviets plan to employearly warning patrols, but this would be within their capabiliUes.

For ground communications in support of air defense operaUons Uie Soviets willto use and to improve high frequency radio and microwave links, and coaxial cable will also continue in limited use. The systems installed during the next five years, especially

i' -


the microwave network, will be capable of relaying signals over long distances without serious degradation and will have lowto Jamming and interception. Wethatore thanercent of the short-distance operational air defense traffic will be carried on microwave links and landllnes. Tropospherlc scatter communica-Uons may alec bc employed In certain areas, such as the Arctic.

Nuclear Weapons

Major advances In yield-to-mass ratio and In fissionable material economy would be Soviet goals for Improvement in air defense warheads, but could be achieved only with the resumption of nuclear tests. In theof such tests, progress In the very low yield category, such as required for air-to-air missile warheads, would be seriously hindered.

At present, nuclear warheads appear to offer the best promise for destruction ofoutside the atmosphere. We estimate that the Soviets would utilize such warheads In air defense systems designed to intercept ballistic missiles and satellites. Two of the thermonuclear devices tested by the USSR8 might lend themselves to antimissileapplications. However, we have noof Soviet nuclear tests at very0 feet or In space) and believe that they lack basic effects data on high altitude and space detonations. In the absence of further nuclear testing, the lack of such data would not prevent developmentuclear-armed antimissile system, but would handicap development ofystem.

Other Bloc Nalionv

he air defense forces of the other Bloc nations will remain inferior to those of the USSR. They will be augmented by theof fighters and antiaircraft guns from Soviet stocks, continued local production of such equipment (largely from Sovietnd the provision of up-todate radar andequipment to serve their own and Soviet needs.

It is unlikely that the USSR hassurface-to-air missiles to the forces of any other Bloc nation, or lhat it will do so until priority Soviet requirements are met. Thenstallations in East Germany are almost certainly Soviet-controlled andfor the defense of Soviet militaryHowever, as the SA-2program is completed in the USSR, the Soviets will probably make this systemin at least limited numbers for theof key static targets. The most likely locations for initial deployment would bc the East European Satellite capitals and major Chinese urban-industrial areas. Judging by estimated trends In thc USSH, limitedofissiles and associatedcould be provided to other Bloc nations beginning1

There are indications that some type of air-to-air missiles may now be in the hands of East German and Chinese Communist fighter elements. In any event, considering that the Chinese Nationalists have used air-to-air missiles with telling effect, we believe that the Chinese Communists either now have or will soon receive Soviet air-to-air missiles. Other Satellite fighter forces may follow suit.

The USSR will probably not providewarheads for Satellite or Chinese use or custody during the period of this estimate. This judgment is based In part on our belief that the USSR's own requirement for airwarheads is very targe, and in part on the reluctance of the USSR to provide nuclear weapons of any kind to the Satellites orIt is possible that the Soviets mightnuclear support to the Chinese in case of need (see,
