PREFACE

This Interagency Intdhgence Report was prepared by trie Central Intelligence Agency withf the Defense Intelligence Agency, the National Security Agency, and the intelligenceof the Departments of Slate. Air Force. Navy, and Army.

The report was prepared at the request of the National Intelligence Officer for Strategic Programs. The analytical and draftingwere carried out by an interagency working group under theof CIA.

The study presents and analyzes the evidence that points to the developmentoviet land-mobile ICBM. and examines thethat seem likely toecision on deployment ofystem. The report is based on information available as of October

SUMMARY

We believe that the Soviets areew land-mobile ICBM and thai the best candidate is the solid-propellanthisis based on the following major areas of evidence:

Planned production of largo numbers ofCBMs.

Development of equipment for theimilar to lhat used by previous land-mobile systems.

INTRODUCTION

The Soviets hive been interests! in bod-mobiie strategic ballistic missiles since, but they have yet to deployhe four land-mobile missiles tested, only theactical short-range Liquid-pro-pellant missile received wide deployment. TheBBM was deployed in smaller num-bori, and programs for two longer-rangeIheHBM and thended in0 prior to deployment.

During tbe, when thendere under development, the Soviets made numerous references In their military press to land-mobile missiles, frequently hinting that mobile medium- and inter continental-range ballistic missiles were already deployed with the Strategic Rocket Foiceslie press articles consistently emphasized lhat Soviet Und-mobile missiles

would be:

fueled by solid propellants, which would give them quick reaction time;

comparatively small; and

practically invulnerable, because they would be highly maneuver able, would

change position frequently, and could be easily camouflaged.

6 and againarshal N. I. Krylov, then commander in chief of the SRF. said that the attention of Soviet science was being concentrated on the development of mobile missiles. In8 statement, Krylov also said that tb* Soviets had solved thisIn general, statements made by SRF officers tended to suggest that mobile missilesbeing deployed, while statements made by non-SRF ollicers tended to emphasize the development of mobile missiles.

In other articles, the Soviets wrotehree-stage, solid-propcilant ICBMthehat could be fired both from silos and from mobile launch platforms-Soch statements declined in frequencylthough as recently1 General S. S. Maryakhin, then chief of Rear Services for the Soviet Armed Forces, claimed that the SRF was becoming increasingly mobile and invulnerable.

SALT STATEMENTS

hroughout the SAL negotiations, the Soviets consistently have opposed US attempts to ban deployment of land-mobile strategic systems.0 Vladimir Semcnov. head of the Soviet SALT delegation, stated:

Land-based ICBM launchers include both fixed and mobilend must be included in the overall aggregate level of strategic offensive armaments on an equal basts with fixed launchers.of any kind of additionalorshese launchers areariety of mobile systems which includeand nuclear-capable aircraft.of land-mobile ICBMould obviously not be any more difficult than. say. verification of submarines and their ballistic missile launchers.

Therefore, justificationan on land-mobile ICBM launchers on the grounds of difficulties of verification by national means appears artificial to the Soviet side.

j

A change in policy indeed seemed poi-siblc at the Moscow Summit. Duringdiscussions at Hie final negotiations that ended with the signing of the Interim Agreement InPSU GeneralBrezhnev reversed tlie position taken by the Soviel SALT delegation and agreed to ban mobile ICBMs. Shortly thereafter, however, the Soviets retracted Brezlincvsagreement on this issue. Whether Brezhnev was ill-informed about the Soviet position and simply had made an error, or whether the Soviet military refusedromising program cannot be determined.

ailing to limit land-mobile missiles in the negotiations, the US unilaterally stated that if

ould consider the deployment of operational land-mobile ICBM Launchers during the period of the Interimas inconsistent with the objectives-of that Agreement.

**T" tt ait Mi

Inlter months ofa preliminary agreement was signed stating that

acilities remaining at (deactivated) ICBM launch sites shall not be used for storage, support, or launch of ICBMs but may, at tlie discretion of the parties, be used for purposes not inconsistent with Ihe provisions of the Interim Agreement 3nd the Protocol thereto.

t SALT, Soviet unwillingness toa ban strongly suggests that they are keeping open an option to develop and deploy mobile ICBMs. This may have been atofor an arms agreement.

I the Soviets havehat would not preclude the use of deactivated ICBM sites as support bases for mobile MR/IRBMs. Furthermore, theagreement docs not coverSovietndR/IRBM sites. These sites, which have as many supportasrCBM sites and which, in any case, have presurvcyed, fixed field sites, could be used toobile ICBM. Some MR/IRBM complexes are being used to support the mobilecaleboard. aballistic missile, which is deployed at isolated field sites.

POSSIBLE DEPLOYMENT MODES

and-mobile ICBM could be deployed in various modes including road-mobile,mobile, shelter-based, and rail-mobile. There is evidence that suggests the Soviets are comidering both the road-mobile and ofl-road mobile coricepts but no clear evidence to suggest lhat sheller-based or rail-mobile systems are under development.

c believe lhat the Soviets would elect to use existing SRF installations as support

There ate numerous arras around SRF installations which arcfor mobile ICBM deploymentupport bases used by tactical mobile missiles also might be employed.

Rood-Mobile and Off-Rood Mobile Concepts

Any SRFw.th adequate support facilities could serveupport baseobile system. Tlie use of siteformeroftat Plesetskupport area suggests this possibility. Missile units could be rotated among various presurveyed fixed field rites, perhaps as fir as SO miles from the support base. The revetments near sitet Plesetsk suggest that the Soviets are considering the use ol fixed-field sites for the mobile version of thesee.

nother deployment possibility is the use of any unprepared, presurveyed area, suchoad intersection,aunch point. There are miny unimproved road networks, especially in the forest regions of the Soviet Union. Some of theseail-served, and supporl bases could be established (here.

Incenlives for Deployment

The principal incentive, fortrategic missile systemobile mode is to increase its survivability.obile system can move to and occupy any launch position within its radius of operationandom fashion, its location at any given time would be difficult for an Opponent to predict forng purposes. Extensiveimc satellite reconnaissance coverage would help to monitor the movementsobile missile force, but surreptitious movement could be accomplished at night, under cloud cover, or by the use of camouflage. In view of USin improving its capabilities against hardened targets, deploymentobile ICBM might be attractive to the Sovietsupplement to other measures to increase the survivability of their ICBM force.

The Soviets may also view deploymentobile ICBMedge against thelapse of the Interim Agreementhe developmentobile system would provide themurvivable forcefor deployment in the event of lapse oi abrogation of Ihe agreement.

Institutional momentum may haveto the development of theobile version and may also ntililate for in deployment. The missile was underseveral years prior to the signing ol the Interim Agreement and its advanced stage

of development undoubtedly was ain the Soviet refusal to ban mobile ICBMs. Institutional considerations mightthe Soviet decision on deploymentobile ICBM, especially the momentum gen-eraled in Ihe military and in various ministries responsible for developing and producing the missile.

the Soviets may see thedeploymentobile ICBM as achip in SAL negotiations to breakover issues they deem crucial.

Mobile systems require morethan fixed systems because movement, vibration, and exposure to the elements cause more frequent equipment failures. Logistic support mightroblem because of tbe distances involved and dispersion of support units.

Because of their size and weight,ICBMs could present other operational problems in moving about the countryside. The solid-propcllantor example, is in theetric ton weight class (notthe TCI. or resupplyheweight limitation for vehicles on Soviet road networkshole is six metric tons per single axle. The tactical Scalrboard-launcher, which has four axles and an estimated grosstheofetric tons, exceeds this limit by aboutercent. On roadscapital' surface (such as cement or asphalt concrete) the single-axle limit isetric tons, but these roads arc located in areas of high population density and areissile unit would want lo avoidon unimproved roads would be limited by the load capacity of the bridges Most of tbe bridges on Soviet country roads have load limits ofetric tons. Snow and rain on unimproved roads arid launchalso could present formidable obstacles for movement to assigned launch position? (tee

hyucal security is more difficult to maintain with mobile missile units than with fixed-based deployment. Countering thisrequires additional personnel for security purposes anil places additional demand* on npci-itiug crews.

trategic Bucket Forces command anil control procedures emphasize positiveto prevent accidental or unauthorized use of nuefcir weapons whileapability for quick strikes. Deployment ofohil' missile poses special command and control problems not experienced with fixed missile systems. It is difficult, for example, lo make mobile communications systems as reliable, secure, and redundant as fixedand to ensure uninterrupted control of mobile launchers by higher echelons ofAbove all. the command and control system must guard against the possible loss of contact with any portion of the mobile forceritical moment.

GEOGRAPHIC FACTORS AFFECTING DEPLOYMENT OF LAND-MOBILE ICBM SYSTEMS

one-fourlli of the USSR, orillion square miles, is considered suitable for deployment of land-mobile ICBMs. Most Soviet railways and all-weather roads are located in this area, which comprises the European USSR, the North Caucasus, the Ural Mountains, western Siberia, and(see. Also concentrated in this area are most MR/IRBM and ICBM complexes and regional nuclear storagethat are dependent on the transportation network.

In addition to the principal all-weather roads there are many fair-weather country roads, especially in agricultural and logging areas, that couldand-mobile system. These roads and even good trails arc suitable for movement of land-mobile systems if the terrain is fairly level. Wherever these roads intersect streams, however, the weightof bridges mightestrictive factor. Moreover. Soviet country roads ore usually little more than graded earth and

become viilually impassable during periods of rain, snow or thaw. The agricultural regions in the Ukraine, in Belorussia, in the Baltic slates and south of Moscow, with theirof main and secondary roads, would be suitable for on-road or roadside mobile

Off-road mobile ICBM units also could be deployed away from the mainnetwork (see Figureorepending on terrain, areas for off-road deployment areas either good-lo-fair orn good-to-fair areas, cross-country movement up lo SO nautical miles (nm) from the mainnetwork is considered feasible. If these areas also contain an SRF facility, they are considered well suited for mobile deployment. The total area in the good-to-fair category covers about one million square miles.
