In view of Soviet agreement to the treaty on peaceful uses or space as well as theultiple orbit bombardment system, we do not believe that the Soviets will deploy and maintain weapons in space during the period of this estimate.

During ihe past two years the Soviet space program has retained its high priority among major national objectives. It has placed slgniflcandy increased demands on the economy lor scarce resources of the same general type and quality as those required for strategic military programs and for investment lor economic growth. The number of space launches attempted In this period nearly equals the total number of launches attempted in the previous seven years.

The Soviets scored some dramatic "firsts" during this period, including the spacewalk by Leonov during the Sight of Voskhod IL the lunar soft landing ofnd the lunar orbitingut in general, their achievements in space were much less spectacular than previously. For the most part, they exploited available hardware, especially boosters, to engage in unmanned space exploration, an fntensivo photoeexmnaissanoe program, and an expansion In the scope of their space applications.

The Soviets have, however,igh priority to researchnd D) on new space systems. Three new programs were brought to Eight phase during the past two years: theound) Protonwhich were launchedillion pound thrustaneuverable satellite capable of small orbital adjustments;ystem which probably relates to the development of fractional orbit weapons, depressed trajectory ICBMs, or both.

No high speed reentry tests to. simulate lunar return problems have been conducted, and no water landing and recovery techniques which probably would be required on lunar return have been demonstrated. Most notable, however, is the hiatus in manned space flights of any kind in tbe nearly two years since

F. Military Systemsrecon naiitance

The Soviet photoreconnaissauce satellite program has continuedigh rate (about two launches per month) over the past two years. This program has enjoyed one of the highest priorities in the entire Soviet space effort,for almost half of all space launchings during this period. The high priority and the use of time-tested hardware, have made the photorcconnaissancc effort the most successful of all Soviet unmanned space programs. The program involves two basic types of reconnaissance vehicles. One payload weighs0 pounds andow resolution photographic missionround resolution on the order ofoeet under average conditions) and probably collects Elint as welL The second type of payload weighs0 pounds; itigher resolution photographic mission, and we believe it achieves ground resolutions on the orderoeet under average conditions.

j To date, no Soviet fligbt tests or rpaoc launches have been delected which used nigh energy propcllants in any of the stages. However, we believe some phases of static testing are now being conducted and flight testing could begm. possibly as part of the development of the system intended for Area J. and that0 or shortly thereafter high-energy upper stages could be man-rated and available for use with existing or more advanced space Lunch systems. Such upper stages will increase tho capability and efficiency of the launch systems available to the Soviets and permit considerable flexibility In planning future space missions.

aunch Vehicles. In all their major space activities7 throughho Soviets used military boosters fitted with additional upper staging. The present Soviet inventory of boosters and the wide range of their payload capability have allowed them toiversified program. To undertake more complex space missions in the future, however, the Soviets are evidently now being forced to develop large boosters specifically for the space program: their military vehicles are not adequate for such missions. The chart on the following page depicts the various launch vehicle configurations the Soviets havo used to date and shows the SI, {space launcher) designations we haveo each.

he booster designated SL-B, which is used in the Proton satelllto program, is the first Sovlot booster which we bellevo will be used solelypace Uunchcr.

Ifere, in fact, the first testew spacecraft, an initial manned flight could occur bye believe the Soviets will develop still larger and more efficient manned space vehicles which will allow more sophisticated and venturesome missions to be performed.

Command and Control for Sear Earth Orbit. The Soviet capability to undertake complex earth orbital operationi is limited by certain majorin the USSR's command and control network. Some existing deficiencies relate to point-to-point communications within the USSR; these will probably be eliminated in the near future as tho internal network of long distancebecomes operational. Although we believe the internal commaiMl and control network generally will be adequate lo support most single missions, the lackorldwide tracking and communications network may handicap the Soviets In the performance of some orbital operations and willevere handicap if the Soviets attempt to control several operational systems, each consisting of several orbiting vehicles. Major improvement to Soviet tracking capability would result from additional tracking stations almost any place outside the USSR. Soviet interest in acquiring tracking stations abroad has been high. Cube, wliere the Soviets have installed an optical tracking station and are going toalniya receiver station, inay^bc the site of the first Soviet land-based tracking station outside the territory of ihe USSR. Soviet efforts toracking station in Australia have been frustrated. Current Soviet activities In the UAR and Somalia may foreshadow attempts to establish tracking stations In one of those countries.

Command and Control for Deep Space. The deep-space tracking facilities located in the Crimea and currently used in unmanned lunar and planetary flights limit tracking and communications to interrupted schedules. Tbe actual time available for tracking and conmiunkatioox for lunar probes depends upon the lunar declination and varies fromoay. We believe that the ability to track and communicate with manned lunar flights4 hours per day basis Is needed to help insure the safety of such missions. The Soviets



could, however, undertake manned lunar flights even with their limited tracking and communication capability by accepting the calculated risk of not being able to communicate with the spacecraft for certain periods of time If the Soviets constructed facilities in their Far East areas, they could increase significantly tbe time available for contact with their lunar missions There is no evidence that any facilities comparable to those in the Crimea are being installed elsewhere, however, and we believe their construction would require at least two years.

The Soviets could also extend the time available for comrnunicatfng with their lunar mlssloa by using appropriately equipped ships as relay centers between tbe spacecraft and the control center. To be effective,ystem wouldigh capacity communications link between the ship and the control center. Without this high capacity link, communications would be limited to relay of verbal instructions and system status summaries and would not permitositive mission control. We have no evidence that the Soviets have installed the necessary equipment on any of their surface ships as yet butystem using such shfpbome relay links is well within their capability. Tlie Soviets could conceivably use communications satellites as relay linkssurface stations for deep space flights.

Rendezoout and Docking. Critical to many advanced types of manned space missions is the requirement to develop techniques for rendezvous and docking of vehicles in space. New Soviet spacecraft, unlike the Vostok and Voskhod, will probably be designed for rendezvous and docking and willthe necessary equipment for maneuverability, engine restart, aod hook-up. Soviet technology is sufficiently advanced to make available the various sensors required for such spacecraft, ie, radar and transponders. Ifere the initial testsew spacecraft designed for rendezvous and docking, the Soviets could conduct initial manned missions of these types using currently available launch systems within the next few months.

ecovery. The point of reentry into the earths atmosphere of lunar return trajectories would lie betweensouth andnorth latitude on the earth's surface, depending upon the declination of the moon at the time of the flight. The Soviet land mass Iks well north of this band. Thus, any spacecraft which did not incorporate some means ror altering its reentry trajectory could not be recovered wit bia the USSR. Since we believe having an on-board propulsion system for altering reentry- trajectories would be impractical, the Soviets need topacecraft having some aerodynamic lift characteristics or,toater recovery capability. There are no firm indications that tbe. Soviets have conducted aerodynamic reentry tests or that they area water recovery capability but tests of either could begin at any time. We believe that tbe time required toecovery technique would notimiting factor io the Soviet manned lunar program.

eentry. Some Soviet scientists have indicated that reentry at lunar return velocities is one of the major problems confronting them in their lunar program. The angle of reentry into the earth's atmosphere must be kept within


narrow limits. If the angle it too steep, accelerations would be too greatanned spacecraft to withstand. On tho other hand, if the reentry angle is too shallow tbe spacecraft would "slop" ofi the earths atmosphere back into space,

n additional reentry problem is that of heating. Tbe ablative material used on the Vostok would be adequate topacecraft having nolift characteristics. Heat shieldingpacecraft having some degree of liftifferent problem because tho heat abiorbed is greater.the higher aerodynamic forces exerted on tbe spacecraft would tend to strip away the heat shield material.

e believe that the Soviets will have to test their new spacecraft, whateverupe, under conditions expected on lunar return najertories. Boostedfrom earth orbit or from high altitude ballistic trajectories could produce some necessary test data, but for fell scale simulations of lunar return velocities, tbe Soviets must conduct an unmanned drcumlunar flight ot wait until theehicle is available.

Oi Board Power. The majority of Soviet spacecraft flown to date have used chemical batteries or solar oefls for electrical power supply._jSoviet chemical-efficiencies of aboutart hour/pound, which compares favorably with current US capabilities. The Soviets could increase this figure toatt hour/pound if they feel the need to save weight, Radirnsotope/thermoelectrio conversion systems which were used in two Soviet satellites orbited5 delivered^ _Jwarts of electric powerapacity far too small to be usedife support system.

During theears the Soviets have been pursuingirected toward the development of fuel cells. Performance testingl cells using the hydrogen-oxygen reaction principle Is probably underway

Biomedical. The Soviets probably now have sufficient biomedical data to plan withanned flighteeks; this would be adequate foranned circurnlunar or lunar landing minion. At present, however, the Soviets appear to be corscerned with the effects on human beings oflonger duration flights (Le^ aboutays orhere are few indications of how they wfll solve the biomedical problems associated with flights- of that duration, but we believe that practical solutions should be ready in time for long-duration projects In the next few years.

Tlie Soviets have numerous facilities for simulating various aspects of space environment including centrifuges for C. stresses, low pressure and lowchambers, suspension devices for simulating reduced gravity, and various devices and equipments for experimentation with men and animalt in closed


environments. These facilities and activities are probably adequate to support any of tbe various manned space ventures they may attempt.

Life Support Systems. In their manned space flights the Soviets haveife support system based on an air-like mixture of oxygen and nitrogenea level pressure of onehe Soviets have apparently been able to scale up tbe system0 toan-day limit. They probably can adapt this system and their experiencemall manned earth-orbiting station as well asanned circumlunar mission. For future missions in which weight wouldreater limiting factor or in long duration Sights, suchanned lunar landingarge space station, wholly new techniques probably would be required. These could be partial regenerative or closed loop systems. The first Soviet flight withew environmental control system would probably be experimental and probably would involve limited objectives, primarily biomedical in nature.

Orientation and Stabilization. The Soviets haveigh degree of precision in the orientation and stabilization of spacecraft when the mission requires iL On those payioads where such pointing accuracies arc not required, the Soviets have utilized spin stabilization or have tolerated random tumbling. All Soviet space vehicles requiring accurate earth orientation have been provided with fully automatic systems. In manned vehicles, the automatic system is backed upanual system which can override the automatic system when necessary. Tbe manual system is capable of accuracies consistent with the safe recovery of die manned vehicle.


from the scientific and technical considerations which wc havethereariety of other factors which will influence the scopeof future Soviet space endeavors. These include such things as tbepast decisions, the views of the present Soviet leaders on the benefits tofrom their space program, costs, the need for regaining lostSoviet views on the US orocram.

Broad policy directives on all space matters are probably issuea riy the"Politburo of the Communist Party of the Soviet Union. We believe that these directives are implementedigh-level commission composed of both government and party officials. This commission probablyParty Secretaryesponsible for defenseV. Smirnov, Deputy Chairman of tbe Council of Ministers, and M. V. Keldysh, President of the Academy of Sciences. The Mtalstry of General Machineheaded by S. A. Afanas'ycv, supported by tbe industrial ministries such as defense, aviation, radio, and electronics, probably is responsible for theand production of space hardware. The Academy of Sciences provides scientific expertise to the entire space effort, controls scientific programs, and



principally through Iho Commission for ihe Exploration and Utilization of Spaceponsor* representatives at interruitional meetings.

lie Soviets almost certainly have already decidud the nature of tlieir space program for the next five years and have probably established antimetable for the various activities related to that program. While it is possible to stretchrogramonger period oi time than originally planned or even to speedrogram somewhat to meet new deadlines, it is extremely difficult torogram In its late stages to meet an entirely different objective than was initially established. While the present Soviet leaders may try to effect econorniAs in certain sectors, we consider it unlikely that they can, at this late date, effect any basic changes io (he overall nature ofprogram for the next five years

we estimate

that expenditures in the Soviet space program have been rising at an average annual rata roughly equivalent to USillion2 when aboutillion were expended,6 when about SS billion were expended. Much of this increase is accounted for by the major launch systems at Tyuratam and the associated program represented by the coostructkio of Area J.s not yet complete and the booster for use there has not yet been seen, but we believe that the program is sufficiently advanced to permit the overall cost of the Soviet space program to level off shortly and hold al about5 billion per year for the next few yean. These costs include our estimates of boih the military and ncmmilitary portions of the Soviet space program.

The/iecendy signed Ouler Space Treaty is not likely loignificant eHecl on the military or nomnilitary aspects of the Soviet space program. Tlie treaty prohibits the establishment of military installations, the testing of any types of weapons, and the staging of military maneuvers on celestial bodies. It also bans placing nuclear weapons ln earth orbit and on celestial bodies, but it does not prohibit tbe development or testing of delivery vehicles for an orbital or fractional orbit weapon system. Further testing of theystem would not be contrary to the treaty aa long as such tests did not Involveuclear weapon in orbit Deployment of an operational system oo the ground is not prohibited.

The treaty permits the use of military personnel and equipment for the peaceful exploration ofexample,anned space station or for conducting scientific research on the moon. While there is no specific mention in the treaty of satellite reconnaissance, the Soviets made tto effort to revive their old charges tbat such activity is Illegal and they seemed to accept It as legitimate.

Tbe extent to which the treaty wfll help the USSR lupplement its own space tracking capabilities is uncertain. According to the treaty, parties to the treaty 'shall consider" requests of other signatories to be afforded anto observe the flight of tbe requesting state's space objects; the nature

of this opportunity, ai well as the conditions under which il would be afforded, would be determined by agreement between tbe states coocmtxxI However, other signatory rations are not obliged to grant any Soviet request for observing itspace objects when they are out of view from Soviet territory.

For these reasons andtho capability of the space hardware which they arc now developing,believe that tho next five years willeriod in which the Sovietsspace ventures far more complicated and spectacular than


considering developments in the Soviet space program over theyears, we can estimate feasible extension of all current projects but itto determine which specific missions will bo flown. We do notSoviets have at band all of tbe necessary technical and economicundertaking all projects anrultaDeously. We therefore believe thatprojects wiD not be attempted, others will be slowly paced, andresources wiD be cotrimrtted toew. The expansion of theproject over the past two years shows that projects ofvalue can and will be funded. Whilelear that usefulstill be accomplished with existing hardware, ft is equally clear thatand sophisticated missions will have to await the newunder development.

The Soviets In their many official and unofficial statements about their space program, have given no roo'ication of what the order of priority is to be. Indeed, much of what is said is conflicting or ambiguous. In arriving at likely dates for specifice haveigh but not complete level of successharing of priorities among several categories of projects. In general, the Ukoly date for any given mission wouldear or so later than that which we consider to be tbe earliest practicable date. We note that delays and failures have occurred and have sometimes plagued tbe Soviets for long periods. Such difficulties can recur at anyupon theof hardware based on new and more complexcould delay achievementpecific missionear or two.

Tbe Soviet manned lunar landing program and the Urge manned space ftation program are bnge-scale undertakings, both of which require the use of

the system intended for Area J. The dates we believe these ventures can be carried out are based on technical feasibility and do not take into account the order in which they may be attempted. We do not believe they could beconcurrently. It must be understood therefore, that the one which is given priority may be carried out at the time indicated and that the other will be deferredear or so.

B. Monnod Lunar Landing

estimated that the Soviet manned lunar landing pro-

gram was probably not intended to be competitive with the Apollo program as thenimed atime period. We believe this is probably still the case. There is the possibility, however, that depending upon the present Soviet view of the Apollo timetable, they may feel that there is some prospect of their getting to the moon first and they may press their program in hopes of being able to do so.

Several factors militate against their being able to compete with the Apollo timetable as originally planned. The status and pace of construction ofndicate that the launch system will probably not be ready for test until aboutaunch vehicle is available, we would expect toeries of tests for man-rating Uie system extending over atearunar landing would be attempted. In the meantime, the Soviets will need toa new spacecraft, to test reentries at lunar return velocities, and perhaps toater recovery capability, Depending upon the technique selected, they may also need to test rendezvous and docking techniques and equipment.

Some Soviet scientists liavehe Apollo technique and stated that their lunar flight will go directly from earth to the moon's surface and return without any orbital rendezvous required. We estimate that any lunar landing mLssion whichingle vehicle using conventional propellants wouldooster developing considerably greater thrust thanan accommodate. The Soviets have alsoechnique involving the placing of components and fuel on the moon by two or more very large vehicles, then having cosmonauts assemble these components on the moonehicle and fuel it for direct return to earth. This" technique is risky since very accurate guidance Is required to place the manned vehicle sufficiently close to the landing site of earlier flights and there is no provision for an abort of the manned Bight.

Other techniques could involve rendezvous and docking of two or more very large vehicles in earth orbit for assembly and fueling the lunar vehicle, before proceeding to the moon. The Soviets could also carry out two launches to the moon, one for landing on the moon and return to lunar orbit, and another for lunar orbil and return to earth. Either of these missions could be attempted within the capabilities we believe tho Soviets will have when theystem Is available.

however, the Soviets were to develop high energy propellants forupper stages of tbeehicle they could use anyide variety of


mission profiles toan oa the moon and return him to earth. We have estimated earlier that man-rated upper stages using high energy propellents could be available0 or shortly thereafter.

things considered, we estimate that the earliest the Sovietsa manned lunar lamiing. would bee believemost likely date is sometime iaime period.

C. Manned Space Station

Soviets are continuing to voice generalities about manned space(ions. They refer to themost of terms, such as cities in space, giant flying

laboratories, scientific research institutes, refueling stations, etc. Sovietfrequently identify two broad space station functions: to pursue research objectives, and to serveaunching or an assembly base for manned lunar and planetary missions. References to military applications of space stations have been conspicuously absent.

Neither the interim nor ultimate configurationpace station* has been defined by the Soviets. Prerequisite techniquesong-term space station would be maneuver, rendezvous, docking and extensive useful EVA. None of these techniques have been demonstrated in the Soviet manned space program to date, although the Soviets have beenariety of laboratory simulations involving multiman crews for long periods of time.

Based on our expectation that theonventional propeUant upper stage will be used in the manned space program, we believe that this system

The crew could be augmented or exchangedan or twoime by subsequent

e think it probable that the Soviets willanned crrcumlunar flightteprogram having more ambitious objectives as Hs subsequent goals, suchanned lunar landing or manned flights to explore other plancts. The Soviets have sometimes describedlight as one preliminary activity leading up to the manned landing. They may also consider that an early manned drcumlunar flight would pay importanterms of prestige, and couldeans to offset some of the propaganda value of the US Apollo program.

The Soviets couldanned drcumlunar flight by using existing hardware. In order lo do so they would need toenik upper stage to theystem, man-rate this combination with aninal stage, and modify the Voskhod spacecraft to giveidcourse correction capability. Thiscouldayload of0 poundsircumlunar trajectory, which would permit the Soviets torew of twoircumlunar flight. Alternatively, the Soviets may choose toew conventlonal-propellant upper stage designed to be flown with theystem and the new spacecraftidcourse guidance capability inherent in its design.

We believe that an attemptanned circumlunar flight would be preceded by at least one unmanned mission utilizing the same mission profile and hardware. We believe that test Bightseriod of about six months would be requiredan-rate the system and to test the equipment and recovery techniques for water landing which may be requiredanned circumlunar flight.

Optimum "window" conditionsoviet manned circumlunar flight occur during tbeonths^ the year when the moon isortherly declination. For this reason, we believe that the earliest the Soviets wouldanned circximrunar flight would be during the first halft Is conceivable that they would attempt such an operation as an "anniversary spectacular" Inut because of the grave risks involved we believe that it is unlikely that they will do so.

and Planetary Probes

poistcd into the missions of future soft-landers. But if the Soviets continue to employ existing lunar probe vehicles, weight limitations probably will prevent the inclusion of all threehe same mission.

Thus, the data obtained try lunar orbiters wouldanned circumlunar mission as wellanned lunar landing.

Many of the techniques utilized bynd Lunan soft landing on the moon have obvious applicationanned lunar landing mission. However, very extensive modification of the descent and landing procedures used by the recent soft-landers wfll be required for manned lunar landing. Lunarovided more refined data on.tbe physical characteristics of the lunar surface which will be useful in determining techniques and weight tolerancesanned lunar landing.

The Soviet program for unmanned planetary exploration probably has two principal objectives: to collect photography and scientific data by fly-by Drobes, and to make planetary atmosphere and surface measurements, in spite

/ of the failure of tbe Soviets torobe toward Mars during the recent "window" early this year, we believe planetary exploration will continue. The Soviets will probably avail themselves of the next "window" to Venus inossibly using theaunch system. Theaunch system, with its considerable payload capability, willariety of other interplanetary missions to be attempted as the period progresses. These could include Mars and Venus orbiters, Mercury and Jupiter fly-by probes, and Mars and Venus soft-landers.

Applied Satellites

ground terminals

i as part oi the

The Soviets have started construction in the northern and eastern areas-of the USSR as part ot their project to integrate the Molniya communication satellite system into their communications structure. We believe that all of the new terminals will be operational by7 to receive satellite relayed transmissions. We believe that this network will probably continue to expand as more sophisticated communications satellites are developed and that stations will be equipped toroad range ofservices.0 the Soviets probably wfll have tested the feasl-bUity of broadcasting directly to home receivers or to relatively simple community TV antennae.

We estimate that the Soviets wiD launch meteorological satellites innumbers during the next five years; there are indications that they plan

launch aboutf these vehicles duringeriod. Ihe Soviets will probably develop more sophisticated instrumentation for use in theirsatellites to obtain information on such things as atmospheric temperature, humidity, and precipitation. Meteorological satellites may also be used to conduct additional observations such as geological mapping, crop surveillance, and ice reconnaissance.

G. Possible Soviet Military Uses of Space

Throughout the period of the estimate tbe Soviets will experimentariety of space systems which could be used for military purposes. Newspace applications will be introduced as Soviet technology advances and as requirements for such systems arcilitary role for man in space may emerge prior to the end of the period, particularly as the ability to operate manned space stations grows.

Military Support Systems. The launching of recoverable photographic and Hunt reconnaissance satellites from Tyuratara and Plesetsk will probably continue at about the present rate until similar missions of longer duration, or manned orbital reconnaissance platforms, are employed. To improve data handling time the Soviets will probably develop an improved photovideo systemultiple film capsule recovery system for long duration missions; they will probably also use communication relay satellites in an attempt to achieve near-real-time data handling between widely separatedatellite with limited maneuver capability for electromagnetic and pbotoreconnaissance may be developed to meet military needs in the next few years.

The high priority evident in tbe recoverable photographic reconnaissance satellite project will probably be extended to other selected military support systems which the Soviet leaders decide are essential; these will probably include systems for improved global communications and TV relay, weather observation, and navigation,

Offensive Weapon Systems. On the basis of Soviet tests of thesee paragraphs. we estimateirst generation fractional orbit bombardment system using theooster could be deployed in small numbers by7 ort could be deployed in silosfrom those associated with theCBM. This systemj""

If, however, the Soviets were to launch the systemotherly trajectory covering0 run. to attack the us from the south, the cep could be oo the, order3 tup. This tudmxreot ii baud, oo our estimate of Soviet technical capabflltlo^

We have no firm basis for fudging What the accuracy of this system would be la in csrratiannl mode; it could be. somewhat less accurate at an early ioc. If. In the future, some meant for trajectory correction were to be hxarparated In the system, the cep could be improved somewhat.


bombardment system could be developed irom the same hardware aod deployed in the same manner but we believe thatevelopment is unlikely.

There is no identified program which Indicates that the Soviets are developing an offensive space weapon system that would be deployed and maintained in orbit. Several new system components would need toong-lile power source and an attitude reference system. However, much of the space lechnology and hardware currently being tested by the Soviets could be usedasis for tiie development nfystem.

For the foreseeable future, we thinkultiple orbit bombardment system deployed in space will not compare favorably with ICBMs in terms of effectiveness, rehabdity, vulnerability, average hie, and siuiceptibility to loss of control due to accident or couriterrneasures. Tbe Soviet leadership probably would recognize that the deployment in spaceuclear-armed orbital bombardment system would bo an act of major international Import which would intensify greatly East-West hostility andtrong now stimulus to USprograms. In view of tlieae factors, the much greater cost of such orbital weapons, and Soviet agreement to the treaty on peaceful uses of space, wethat tbe Soviets are unlikely toultiple orbit bombardmentIn space during the period of this estimate.

Wc recognize that the Soviet, might reach different concisions as to cost and effectiveness and thai altered political considerations in some future phase of East-West relations might lead themifferent decision, Even in these

he Soviets have demonstrated, as part of their missile and space programs, many of the necessary technologies, subsystems, and capabilities applicableoorbital interceptor development. These Include the precise control of launch time; some of the operational procedures required for rendezvous; orbital transfer; stability and control systems; and an engine restart capability. These provide the technological base for tbe Soviets to develop an initial unmanned coorbital

The interference with orbiting satellites Is prohibited in the spacebut the developmentapability to do so is not We believe that the Soviets

would realize that any use of antisatellite systems in peacetime would risk opening their own military support systems to retaliation. We think it likely, therefore, that the Soviets would use andsatellite systems only if they believed that war with the US was imminent and that neutralization of our military support systems was consequently an overriding consideration. There might also be other specialin which they would use antisatefiitc systems in peacetime; for example, they might believe that they were retaliating against US interference with their own satellites.

H. Unmanned Exploration of Near Space

Their stated plansprobes and satellites for observing solar electromagneticstreams, cosmic rays, radiation belts, magnetic fields, theand infrared and ultraviolet radiation. Many of thesebeen and will continue to be carried out by the small Kapustin YarAdditional satellites may be launched from Tyuratam todata at great distances from earth.

V. THE lONG-TERM OUTLOOK "A. Factors Affecting

have little evidence concerning long-term Soviet objectives incan estimate the likely scope of the Soviet spacenlyery tentative basis. Some cosmonauts, scientists,other Soviet space enthusiasts have often referred to possible futureas interplanetary exploration, but tbe political leadership during the pastor so has made little public reference to space activities, and has avoided


open reference to any particular programs' The leadership has probably not yet decided which particular ventures to emphasize beyond the manned lunar landing era, and almost certainly has been unable to gauge with any degree of precision the amount of resources likely to be available for space programs In the next decade.

The question of resource allocationentral one in Soviet politics. Competition for resources has intensified since the, when the marked slowdown in Soviet economic growth began, and political infighting, in part based on this competition, has become characteristic of life within the leadership. The post-Khrushchev collective leadership has not indicated any substantial ability to resolve problems associated with the establishment of economic priorities; it has as yet been unable to agree on die final version of the current five-year plan, which began moreear ago. In the meantime, competingand space, growth andall, in effect, been assured high priorities.

One of the principal causes of economic difficulties in the USSR duringas been the preemption of highly skilled human resources and top-grade material resources by rapidly growing programs in advanced weapons and space. Among other things, these programs have impinged on the quality and effectiveness of investment elsewhere in the economy, and the present collective is surely aware of this. Aside from efforts to achieve marginal economies,the leadership has not sought to attack the problem by reducing or even leveling off expenditures in these areas, and we estimate that it is unlikely to do so over the next four or five years. If important programs must be cut civilian claimants arc the most likely to suffer, as in the recent past

Whether the Soviet leaders will be witling to approach the problemew way inill, of course, depend on many factors; the state of the cconomv, the international climate, the composition and nature of the leadership, the Interplay of domestic political and economic pressures, the progress of specific military and space programs, the progress and scope of comparable US programs, and the leaderships calculations as to the costs of the program versus Its probable returns, scientific, military, and political. The latter factor, the political, is likely to be of pjirticular importance. The propaganda and psychological benefits of tbe program, both at home and abroad, have always been of prime interest to the Soviet regime; the USSR's pioneeringin space added greatlyTo its mternational prestige and probably helped to justUy the regime to its own people. It may be, however, that such benefits will diminish with time and familiarity, and that Soviet prestige is less likely in the future to increase rignificandy on the basis of individual exploits, such as Sputnik.

the guideline! for the current Five-Yearie quite brief and are tpectfic only concerning the application of space technology to on oo earth: To provide in tbe five-year planhe further study of apace end (he application of the otrtjinrd results for improving radio communications, radio navigation and television, for weather forecasting and for other practical rxupoies."

of Soviet Cooperation in Space Matters

Until recently, the Soviets had staunchly refused to offer any indication that Ibey were willing to cooperate in any field of space activity.2 the Soviets' agreed to exchange satellite-collected weather data with the US. and in6 passed the first of their data to tlie US. This step plus the cooperative Soviet attitude evidenced during the recent discussions on the UN treatypeaceful uses of space and the agreement with France on relay of TV and other cooperative space projects lead us to believe tbat the Soviets will become more willing to exchange various scientific and technical data with the US and other nations as the various programs progress. They may, for example, be willing to exchange such data oo radiation belts, solar effects, gravity anomalies, and additional and more detailed meteorology.

Apart from technical difficulties, there are three factors which would tend to limit the extent of Soviet cooperation in space. Fast, the prestige of being the first nation to accomplish various space missions continues to be Important to the USSR. Second, the prospective gain in cooperating beyond the exchange of scientific and technical data would have to be convincing to the Soviets as long as major international political issues remain unresolved. Third, the close association of military and civilian space programs in the USSR would restrict the areas of cooperation which the Soviets would be willing to consider. We believe, however, that if tbe advantages to be gained are persuasive, the Soviets may agree to some ventures in which compatible equipments could be launched by the USSR and another nation and link together to perform functions of mutualxvrnmunications systemarge portion of the globeorldwide meteorological system. We consider it unlikely, however, that within the period of this estimate the Soviets will be willing to cooperate to the extent of exchanging space hardware.

We have considered the possibility that at some time beyond the lunar exploration era tbe costs and technical complexity of more extensive planetary exploration may be so great that one nation would not consider it feasible or practical to undertake it We believe it less likely that the Soviets would be willing to join tbe USilateral venture than to participaterogram sponsoredroup ofne under the aegis of the UN.


Because we are unable to estimate Soviet intentions in space over the long term, our consideration of possible space activities must rest heavily on our estimates of likely Soviet capabilities in the field. Moreover, even on this basis, we must make tbe assumption that the various projects the Sovietsin the near term will for the most part be successful and that long-term ventures will be able to proceed from earlier achievements,

Soviet writings and oratory haveroad spectrum of potential undertakings In space but have tailed, probably deliberately, to highlight any particular one or ones as those likely to be pursued by tbe USSR. However,

c 3

certain ventures are mentioned more often than others and this repetition may provide the clue to future Soviet undertakings. eview of Soviet writings, speeches, and interviews over the past two years shows that the followingilities are the most often addressed:

expansion of the applied satellite program in the Belds ofmeteorology, geodesy, and navigation.

of the sun and planets.

complex space stations, to serve as scientific research bases,platforms for other space ships, as astronomical observatories, etc.

lunar base or laboratory" toariety ofaunching station for deep space probes,observations, as well asase for the exploration of the itself.

Normally missing from their official statements is mention of programs with direct military applicability. Nevertheless we believe that thej' willto explore military applications of space.

In discussing tbe lunar base or "laboratory" the Soviets are obviouslyto something far more extensive and complicatedather small, two or three man, short duration installation. In these discussions, tbe Soviets do not describe the means of puttingtation in place, but restrict the discourse to desirabilityase of this type and the scientific advantages to be gained. The constructionanned lunar base of the size and nature

' implied in the Soviet discussions would be extremely complex and cosdy, and would require the Soviets to develop equipment and techniques far morethan we believe that they will be able to achieve within the nextears.

There is no evidence that the Soviets areuclear rocket engine for interplanetary propulsion, although they are continuing research which could be applicable toevelopment It would probably take the Sovietsoears, after initiation of the program, to develop such in engine.

However, the steps taken toward these programs arc so interrelated that any step taken in any one program would be of benefit in others. Priority projects will probably be undertaken, but we have no evidence upon which toudgment of which program or programs will be assigned what priority.
