To estimate gross Soviet capabilities for attacks on the US and key


In planning the actual scale of attack on the US and key US installationsUie Soviet rulers wouldhat such an attack would inevitably Involve general war. Accordingly, some portion of the Soviet nuclear weapons stockpile and delivery capabilities would almost certainly be allocated for use against US allies and for reserve. This estimate does not consider Uie problem of such allocation, butitself to the gross capabilities for attack on the US and key US installationsas indicated by the estimated state of Soviet weapons, equipment, and facilities during the period of the estimate.


In attacking the US and key USinstallations the major Sovietwould be to: (a) destroy or cripple as quickly as possible US capabilities for

attack on urban, industrial, andtargets Ln the US as would prevent, or at least hinder, the mobilization of US war potential; (c) inflict such destruction

The Soviet leaders would probablythat in order to achieve success such an attack would have to beunder conditions of maximum surprise. Therefore the USSR would probably launch its initial attacks from such bases and under such conditions as would offer the greatest security from

Throughout the period of thisthe Soviet rulers probably would employ other methods of attacking the US or US installations overseaswith or immediatelyurprise nuclear air attack. They could attack US overseas installations with guided missiles up to rangesiles and could employ airborne andforces, ground forces, and chemical warfare, Clandestine attack on the US itself by sabotage, biological warfare, and placement of nuclear weapons, might occur against specially selected targets.

The submarine force of the USSR could, at least in the initial phases of an

attack, inflict serious damage on UScommunications and carry outmining in the shippingto harbors and ports of the US and itsn addition to its potential for launching mass destruction weapons against the US or key US overseaswithin range.

he USSR would probably employ ground, airborne, and amphibious forces in attacks that occur simultaneously with or immediately after the initial attacks. Soviet ground forces, particularly in Western Europe,igh capability for attacking Allied forces andlocated in forward areas. Theemployment of airborne orforces would enable the Soviet Ground Forces to attack more distant forces and installations.



Nuclear Weapons. The Soviet atomicprogram, directed primarily toward the production of nuclear weapons, will continue to receive special emphasisxtensive reserves of uranium exist within thc USSR and current rales of exploitation of domestic and Satellite uranium deposits will probably continue to be more than sufficient to support estimated fissionable materialIt is believed that the other basic materials required for nuclear energyup tore available ih sufficient quantity as not to cause curtailment of other Important Soviet efforts If nuclear program needs are to be met

Radiological Warfare. It is most unlikely, for technological reasons, that the USSR will be able to stockpile militarily significant quantities of .radiological warfare weapons during the period of this estimate. Although not strictly within the category of radiological warfare, the significance of radio-activefollowing large nuclear explosions becomes greater as the yield of nuclear weaponsThis factor should be considered In connection with Soviet capabilities to produce explosions in Uie megaton range.

Biological Warfare. The USSR Is inof all Uie necessary basic knowledge for the production of most BW agents anddlsseminaUon devices, If the Soviets chose to do so, they would be able to construct and operate plants for BW agent producUon and devices for dissemination could bein adequate numbers. However, there Is no evidence that the USSR is engaged ln liw agent production or possesses production facilities designed specifically for BW agents. There is also no evidence of Soviet stockpiles of BW agents or munitions. Since it is not feasible to stockpile large quantities of most BW agents in prolonged storage, mostrequirements would have to be supplied directly from producUon facilities.

However, inflighttechniques do not impose serious technical problems and the USSR has had access lo the wartime techniques and equipment employed by the US in this field.

Base Areas for Direct Air Atiack on tho US

ive areas within Soviet dominatedare most suitable geographically for launching long-range air operations against the United Slates: the Kola Peninsula area; the Leningrad complex; the Chukotski and Kamchatka areas In northeastern Siberia; and Uie Baltic-East German area. Tlie Chukotski. Kola, and Kamchatka areas are particularly advantageous as bases forattacks since great circle routes would avoid initial overflight of nations friendly to Uie US. The extension of bomber ranges byill not be great enough to allow the enemy to dispense with these areas iftargets In lhe whole of the United States are to be reached on oUier thanmissions. II Is therefore reasonable to suppose that at least until Uie end of Uie period of this estimate any large-scale attacks would involve use of these areas.

CAvJeofski Area. This area Is not known to contain any bases suitable forake-offs at maximum gross weightsoundsfoot obstacle, but does have at least four bases which have undergone post-World War II runway development which would probably make them suitable forunder conditions of either reduced Lake off or acceptance of lower safety margins Among these are: Tanyurerndvailable intelligence docs not permit conclusive determination of the current status of these facilities.

Cold, wind, snow, and log in the area would make air operations difficult and hazardous attimes of the year. The lack of modern navigational aids would also hamperbut there are indications that the USSR is steadily improving ils air operationalin this area through the installation of modern radio navigational facilities. It isthat no long-range bomber units are presently stationed in this area, althoughights have been made to the area.

In addition, security of preparations would be lower In this area Ihan in other forward base areas.

Areas for Direct Altack on Key US Installations Overseas

Sovtet Base Areas. In thc Soviet Union, the European Satellites, Communist China, and North Korea, there areirfields with hard-surfaced runwayseet or over which are estimated to be suitable for operaUons by Jet light bombers, medium bombers, and heavy bombers. Of thisapproximately one-third are located In Uie European Satellites and one-fourth InChina and North Korea. Theare located chiefly in the western and southern USSR and in mariUme provinces of the Soviet Par East. In addition, there areirfields in the Soviet Bloc which are estimated to be potentially capable of accommodaUng Jet light bomber andand heavy bomber operations. We believe that the large number of suitable airfields available could adequately support Soviet bomber attacks against most key US overseas installations.

Soviet Capabilities tor Attack on Key US Overseas Installations. Prom bases In East Germany. Soviet Jet light bombers on two-way missions could reach Uie entire North Sea area, Uie UK and its northern and western approaches (Including therance and ils western approaches, and northeastern Spain. From bases In Hungary thesecould reach the Mediterranean area up to an arc drawn south of Sardinia and Sicily. From bases In Uie southern USSR, they could

reach an area north of an arc Crelc-Israel-Kuwalt, Jet light bombers based In the Vladivostok and Dairen areas could reach all of Japan. To reach Ol.inawa and Luzon on two-way missions, Uicy would have to stage from bases In Communist China.

rom bases in the USSR, Soviet stripped-downon two-way missions could reach key US installaUons in the UK, WesternIceland. Greenland. Ihe Aaores. French North Africa. Libya, the Middle East. Japan, Okinawa. Alaska, Guam, and the northern Philippines. To reach key installationsthese areas. IUwould have lo resort to inflight refueling or one-way missions. Jet medium bombers from bases In the USSR could reach all lhe above areas exceptGreenland (marginal against Thulej. Uie Axores, Guam, and the Philippines.7 jet heavy bombers on two-way missions could reach key US installations in the UK. Western Europe. Far East Including Okinawa. Flench North Africa-Libya, lhe Philippine andIslands, Middle East, Greenland. Iceland, and the northeastern coastrador, Uie Azores, and Alaska. Thend Jet heavy bombers could reach the Panama Canal on one-way missions only If inflight refueling were employed.

argeting and Bombing Accuracy. The factors discussed in Paragraphor long-range operations apply equally to Soviet air attacks against key US lnstalaflons overseas. In addition, It has been established thai radar

bombing byet light bombers has been carried out Qsrktg equipment withsimilar to the USype radar.nits in Eastern Germany are known to have practiced bombing at night and during instrument weather conditions and such practice is probably included In other jet light bomber units. In the absence of definiteon Soviet radar and visual bombing proficiency, it is assumed that accuracies for trained units approach the limitations of the equipment. II is estimated, therefore, that jet light bomber crews could achieveeet for visual bombing0 feel,eet for radar bombing from the same alUtude.

AvailabtUtu, Abort RaU. Replacement Factors. The factors discussed in Paragraphor long-range bombers attacking the-US apply generally to bomber aircraft attacking key US installations overseas. Arale ofercent byor initial atucks from other than the forward northern bases, is considered possible because of the better facilities and logistic support In these areas. The sustained serviceability rate for jet light bombers is estimated to be aboutercent. No reserves of Jet light bombers are believed to exist at present, nor do we estimate an appreciable reserve of this type of aircraft will exist during the period of this estimate.

Electronic Countermeasures. The Soviet ECM capabiliUes discussed in Paragraphpply also to bomber allacks against key US overseas InstallaUons. However, Sovietfor ECM would probably be less because of the less elaborate defenses around most of these installations and Uie shorter limes required lo penetrate defenses before targets arc reached. Space and weightwould probably preclude Soviel jet light bombers from carrying ECM equipmentfor Chaff) In addition to bomb loads. However, Uie USSR has the technicalto produce andet light bomber wiih both passive listening and activeelectronic equipment. No evidence Is available of Soviet inlenUons In this regard.

These three base areas are the closest to lhc US and are so situated asffer the best possibilities for launchingwithout allied delecUon.

In fact, the USSR would probably rely more on Jel light bombers than on piston medium bombers to attack such Installations because of the greater capability of the jet bomber to penetrate allied air defenses.Soviet Jet light bombers would also be engaged in close ground support,air superiority, and mining and torpedo missions in support of other Soviet campaigns, the USSR could probablyufficient number ofet light bombers available4 to attempt to neutralize or destroy with HE or nuclear weapons selected allied forces and installations within range.

It Is considered unlikely thai the estimated force striking Uie US would be decreased to make available additional long-range aircraft to aitack key US installations overseas. Such diversion of long-range aircraft Is alsoin view of the great number of jet light bombers which could be employed against key installations within their radius.

We estimate Uiat7 the USSR will haveet light bombers which could also be available for attacks against key US and allied installations within Uie operaUonal capabilities of these aircraft. We believe that Uie USSR couldufficient number of these jet light bombers lo attempt toor destroy with UK or nuclear weapons selected allied forces and installations within range.

Soviet air attacks against key US and allied overseas Installations could achieve varying degrees of surprise depending on the location of such Installation* with respect to base areas from which Uie USSR could launch attacks. Soviet aircrafl attempting tokey installations In Western France. Spain, the UK. North Africa, and lhe Azores would initially have to overfly lhe Western zones of Germany or Austria or other friendly allied areas and It to probable that defenses would be alerted some lime before aircraft reached target areas. Therefore, surprise would probably notrimary considers-Uon in determining the scale of attack against installations in these areas, since allied de-

tenses would probablymall as veilarge number of. attacking aircraft. On tbe other hand key Installations InGreenland, Labrador, andcould be reached from Soviet base areas without overflying areas friendly to the allies. Attacks against key US Installations In the Middle East could probably be launchedfrom the southern USSR but might be detected approaching or over Turkey, Iraq, or Iran. From bases In the Soviet Far East the USSR could make direct attacks across Uie open Pacific against Midway, Wake, and Guam. To attack Okinawa andirect course from bases in Uie Vladivostok area, Soviet aircraft would have to overfly early warning radar areas In Japan and South Korea.

It Is alsothat accuracies better lhan those quoted will be within Soviet capability.

of this estimate the USSR will be capable of producing nuclear weapons which could be smuggled into the US either as complete assemblies or as component parts or These could range from small-yield weapons (equivalentons of TNT or less)ew hundred pounds lo larger-yield weapons (possibly up lo the equivalentons of TNT) weighing less than ten thousand pounds. Their site could range from thaiackage small enough to fit into lhe luggage compartment of an automobile lo thatacking case large enough lo conUin an automobile. All of these weapons could be designed to break downumber of relatively simple and readily transportable components. Thosetoelatively low yield would not require much labor or technical training for assembly. Somewhat more labor andwould be required to assemble weapons designed to give high yields, and, oncethey would be more difficult to It Is conceivable that only thematerial, in small pieces, need beinto the US. since olher components could be fabricated or procured in this This scheme, however, would require careful advance planning and coordinaUon by supervisory personnel with engineering skill and familiarity with the US sources of needed components, and wouldonger tune to carry out It would probably result in ayieldiven amount of fissionable material. It would alaoubstantially greater security risk lhan the clandestineof all components.

Either components or assembled weapons could be brought In under diplomatic immunity, smuggled across land or seaIntroduced Uirough normal Importor brought in as bonded merchandise

awaiting transshipment Thc selection ol tlic method ol introduction and of transport and and assembly within the US would depend on the Soviet objective and the risk ofwhich the USSR was willing lo accept. Satellite agents and merchant ships could be utilized for such attacks as could Communists in other countries. There are atommunists In Mexico0 In Canada together with thousands of other personslo Communist led labor unions and front organizations that could be instrumental in clandestine attacks against the US. In addition, Mexico israffic center for Communists in North and South America giving Communists from other countriesto the US borders. Although theseelements of other countries could be used, it is doubtful If the Soviets would Incur the risk of using them In surprise clandestine attack against thc US prior to overt military attack.

In Introducing nuclear weaponsinto thc US, however, the USSR would have to take into account not only thechances of detection, but also theof such detection In forfeiting the element of surprise in any Intended overt attack and provoking US counteraction. As the number of weapons clandestinelywas increased, the risk of compromise would increase. This Increased risk would beunction of US capabilities for physical detection then of the scope and complexity of the clandestine operations, particularlyas larger numbers of Soviet agents became involved. Considering the consequencesreach of security, the USSR would probably be unwilling to risk the use of even selected and trained agents in such numbers as would be Involved in the clandestine delivery of large numbers of nuclear weapons. We conclude, therefore, that, although clandestine attack with nuclear weapons might occur against specially selected targetsupplement to overt delivery by air, such attack, with large numbers of weapons, would probably beby security considerations.

Biological Weapons. Most biological<BW> agents are peculiarly adaptable to

clandestine utilization, since the introduction of small amounts of BW agents would beto detect. Small-scale employment of biological warfare agents against livestock could be highly effective.

Atlacks by Ground Forces and Tactical Air Forces

Many key US installations overseas, such as those in Western Europe, the Middle and Par East, are subject to attack by Soviet ground and tactical air forces. Suchhowever, would almost certainly be an integral part of the over-all Soviet campaign in these areas, and it would be impossible to separate the specific scale of attack on key US installations from the over-all scale of Soviet campaigns.*

Amphibious Attack

ecause of the lack of long-rangetype vessels and aircraft carriers, large-scale Soviet amphibious attacks will be limited to areas where air cover can befrom Communlst-conUolIed territory. However, amphibious raids by submarine-borne forces for the purpose of attempting the destruction or neutralization of key USinstallations are possibleadiusiles from Soviet submarine bases Amphibious assault against Uie continental US (except Alaska) is beyond SovietIn assaults against Alaska, logistic problems, weather, and Uie requirement for air cover would probably limit the scale and duration of such attacks to raids in force to destroy or neutralize US Installations In Uie Aleutian Islands or along the Bering Sea coast. Amphibious attacks against key US overseas installations, except in the Far East, would probably be limited to amphibious raids by submarine borne forces. Amphibiousin considerable force could be made against US Installations In Japan. Okinawa, and Formosa

Airborne Attack

The capability of these forces to seize and destroy key USoverseas Is limited by the availability of transport aircraft. The USSR can utilizewo-engine transports which could lift0 paratroopersaximum Initial assault and0 troopsive-day assault operation in Western Europe. The operaUonal radius of such assaulU would beauU-cal miles This capability will7 with Uie addition of new medium transports The most likelyof airborne assaults would be theof key US Installations, the seizure of bases, nnd the securing of important com-


features in Western Europe. Japan, and Alaska. Because of air transport limitations, the USSR will not be capable of launching major airborne operations against the continental US during the period of this estimate. However, small, highly-trained assault groups probably could be delivered to some targets Ln the US.


The USSR Is capable of widespreadin thc US through the use of existingelements and the placement of foreign agents, However, such sabotage effortswould not be initiatedarge scale prior to an all-out attack on thc US since such efforts would nullify the advantage of surprise. Large-scale sabotage of USindustrial, and communicationsand military Installations could be expected with and immediately followingaltack by the USSR. Communist party members and adherents are capable ofsaboteur unils or teams of varying sizes equipped with small arms and other suitable material which could strike at especiallyand widely separated targetsand without warning. Whether such attacks would be timedurpriseattack or carried out after such anwould be dependent upon the Sovietof thc relative advantages of such action.

Soviet capabilities for widespread sabotage attacks againsi key overseas bases are greater than against the continental US. because of the much larger percentage of Communist elements, widespread political discontent, and lack of adequate security measures In certain foreign nations. Those areas in which such capabilities are now greatest are France. Italy. Japan, and the Philippines. However, in numerous other countries the Communists almost certainly have capabilities for acts of sabotage. The populations of these areas arc experienced in such operations and sabotage

efforts timed with large-scale military attacks could materially reduce the capability of US military forces overseas.


Probable Soviet Strategic Objectives

n determining the scale and type ofattacks on the US and key US overseas installations to be adopted in event of general war. the Soviet leaders would be influenced by the following factors:

power of the US is the mainFree World opposition to theand the main obstacle todomination. The USSR wouldthat if US war-makingbe sufficiently reduced lnar, organizedthroughout the world wouldcollapse.

Installations, as well as those In the US, would be essential to neutralize the USair capability.

e. Soviet leaders also must realize thatforces and Installations, as well asUS allies particularly In Eurasia,obstacles to Soviet success Inthat will occur simultaneously withafter the Initial attacks,

In view ol the above factors il is likely that the USSR in attacking lhe US and key overseas installations would have themajor objectives: (a) to destroy swiftly or cripple US capabilities for nuclear retaliation; (b) lo deliver such an attack on urban.and psychological targets In the US as would prevent, or at least hinder, theof the US war potential and itsoverseas; and (c) to inflict suchon US overseas installations as to hamper or prevent US reinforcement andsupport of overseas forces. To achieve these objectives we consider it almost certainortion of the Soviet nuclear stockpile would be employed against certain key USoutside the continental US. We believe that these Soviet objectives wouldthe same throughout the period of this estimate although Soviet capabilities for achieving them will obviously Increase

Desirability of Surprise. In order to be successful, an attack on US nuclearwould have to be accomplished with almost complete surprise. It is therefore probable that the USSR would launch initial attacks against the US and key overseasIn size and from base areas which would offer tbc greatest security fromwith attacks by other forces against other areas after the element of surprise had lost its significance.

A maximum Soviet attack on theUS, and key overseas Installations,utilization of all or most of thediscussed in this estimate, wouldpreparations that would almostresult In the toss of surprise. Therefore, if the USSR attempts to achieve maximum

surprise it will probably be forced to accept the following major limitations: (a) no large-scale mobilization of additional units; (b) no large-scale redeployment of Soviet air, naval, or ground forces to reinforce peripheraland (c> no unusual movement of Soviet air, naval, or ground forces In such areas as would be likely to Indicate theof attacks

Probable Methods of Attack Against the US

Nuclear Attacks by Aircraft. In view of the desirability of achieving both maximum surprise and maximum weight In any atiack on thc US, we believe that the USSR would place chief reliance on nuclear air attacks. Among thc forces and weapons available, the USSR's greatest capability lies in overtattack with nuclear weapons delivered by long-range aircrafl. It is probable that such attack would receive the highest priority because) the limited capabilities ofnaval forces, ground forces, andforces against the US; (b) thc security difficulties inherent In the delivery of large numbers of nuclear weapons by clandestine means; (c) the insufficient development of other methods of delivery of nuclear weaponsarge scale; (d) the Insufficientof other mass destruction weapons, or handicaps to their large-scale use; and (e) the availability of far northern air bases, from which air operations against the US are least susceptible to detection.

Other Methods of Attack. The Soviet rulers might, however, employ other methods ot attacking the US concurrenUy withurprise nuclear air atiack. Soviet capabilities for airborneand chemical and biological warfare, againsi the continental US. appear lo beslight, aandestine attack In the form of sabotage, biological warfare, or use of nuclear weapons might occur againstselected targets. Guided missiles could be launched from submarines against US ports and coastal installations.

Probable Methods of Attacks Against Key US Overseas Installations

The USSR woulduch wider range of capabilities for effective attack on many key US Installations overseas than on the US Itself because of the shorter ranges, greater possibilities for clandestine action, and other factors Involved. However, wethat If the USSRurprise attack on thc US Itself. It would time its attacks on US Installations overseas so as not to compromise the achievement of surprise against the US. Thus Initial attacks on these installations would probably take place simultaneously with or shortly after theon the US. and prior detectablewould be avoided to the maximum extent These considerations wouldaffect thc scale and timing of tlie attacks discussed below.

Western Europe and the Middle East. Attacks on tlie majority of key USIn these areas (except the UK and Spain) probably could most profitably beout primarily by ground and tactical air forces. The SovieU have the capability to launch attacks on these areas from Soviet-controlled territory without Increasing their forces, but might elect to carry out at least partial mobilization to insure the decisive success of the operations.

Other Overut alia lions. Except for Japan, Okinawa, and Formosa. USin other areas would be subjectto air attacks with nuclear andweapons. Sufficient Soviet jet light bombers nrc now available in peripheral areas occupied by or under the Influence of


the USSR to permit large-scale attacks on [retaliations in the UK. Turkey, and theEast. Attacks In considerable force could be launched by amphibious and airborne forces against Japan. Okinawa, and Formosa. Overseas Installationsoues of Soviet submarine bases could be subjected to amphibious raids by submarine forces and virtually all overseas Installations are subject to nuclear attacks by long-range aircraft. In addition thc Soviels possess the capability of making atlacks on selected overseasby special small airborne teams and could mount large-scale airborne attacks on Installationsadiusaulical miles of Soviet bases.

ikelihood of Change In Primary Methods of Attack throughovietfor all methods of attack will Increase considerably by7 asresult ofaircraft, an enlarged stockpile ofweapons. Increased naval strengthpossible utilization of submarine launched guidednd ground forces probably supported by weapons employing nuclear warheads. However, the choice of pnmary method of altack will be unlikely to change materially because the Improvement of Soviet capabilities In any particular field will probably not be sufficient to guarantee success against the US or key US Installations overseas. If anything. Soviet capabilities for large-scale nuclear air attack on the US will increase more during this period than Soviet capabilities for use of any other weaponsagainst the US. In addition, however,7 thc USSR could have substantially Increased capabilities for use ot guidedparticularly against US coastal areas and key Installations overseas.
