SUMMARY AND CONCLUSIONS

The Stage ond Direction of Ihe Chinese Effort

someears of effort, China is now beginning toweapon systems. Starting from scratchimitedtechnical, and scientific base, and denied Soviet assistancethe Chinese had to proceed on their own with therequisite skills, the constniction of basic facilities, and thetesting of nuclear weapons and delivery systems,

clearly intends to attain the statusajoraccepting the economic burden involved and the risks ofbasic economic development through diversion of scarceskills to specialized defense tasks. This is evident on thetoday where activity in both general purpose and strategicprograms is at an all time high. Though any forecast ofmust allow for additional periods of disruption and upset.reasonable to assume thai the existing high priority forwill endure in the years ahead.

China's efforts in the military field will beavailable skills and resources. But we lack the data to placeceiling on the level of the Chinese effort. Based on theChinese mililary programs to date, the Chinese seem sensitivedangers of trying too much too fast in their strategica country whose population growth threatens continuously toeconomic growth- While stressing the wide-ranging andof China's present effort, we should also stress itspace. The Chinese have been deliberate in testingand in no apparent ruth to undertake cosily and large-scale

It seems most likely that Peking seeks throughubstantial nuclear force to enhance its claim tostatus, to deter the USSR and tho US from the resort toChina, and to insure foreading and dominantin Asia.

We judge that China could have SSBNs equipped with solid- or liquid-propellant missiles as earlyut this wouldrash effort and early success inultitude of support, training, andproblems.

Over the next few years, we expect continued launches involving larger and increasingly sophisticated payloads, partly in response to urgent military needs for targeting and geodetic data.

N. We expect whatever strategic forces China now has deployed to be augmented gradually over the next two years, principallyuild-up ofnits and by the continued series production ofedium bombers.3 and for the period five years ahead, there is much uncertainty {Section VI attempts to project to thatut one thing is certain: the force will be weighted heavily on the side of systems capable only of reaching targets in AsiaUS installations there) and theapability against the continental US may begin to emerge, however, toward the end of this period.

The evidence on (he system to befor storage and handling ofight be pcKuhle to infer something as to command andis still very limited. We believe thatational stockpile, facility toany weapons they may havefor stockpile. Operational storage sites for nuclear bombs at airfields have not been identified in China, but we cannot rule out the pom bib tv that some nuclear weapons may already be dispersed to temporary storageat some bomber-capable airfields

Nor have facilities constructedto store missile warheads been identified. With deployment of operational missile units the Chinese probably will provide facilities at the missile site or with the unit for check out and mating of the warhead and possibK* for separate or temporary storage.

We do not know whether the Chinese will keep nuclear warheads with missile units continuously or keep thementralor stockpiles, delivering them tounits onry in times of crisis. Missiles deployed at soft sites will probably not be continuously on alert, and the Chinese couldogistics system to rapidly deploy warheads from nearby stockpiles to these sites while the missiles were being readied.in hard sites can be keptigher state of readiness for extended periods, and when silo deployment begins the Chinese almost certainly will keep warheads at the sites or on the missiles.

D. Nuclear Materials Production

he only gaseous diffusion plant known to be In operation In China is at Lanchou. This plant is based on early Soviet designs and was begun with Soviet help.

here is no informalion regarding any major construction at Ihe Lanchou plant since its stait up. The Chinese may have begun some minor modifications to upgradesome of the equipment; but, even so, such improvements would lead only toproduction increases well within theestimated ranee of production. Thus, we do not believe that production at this plant will be uBTUticantly upgraded during the period of this estimate

This apparent hiatus led to increasingthat the Chinese did not intend, after all. to deployroduction program for theombers was underway which could provide an interim strategic force clearly able lo carry China's TN weapons. The picture began to change. however, as evidence accumulated ot new activity involving the MRBM.

f this activity means that China has begun deployment of the MRBM. it still does not account for the apparent two to three year

gap between completion of the development phase and deployment. Nor does il account for the apparent decmon to resumeime when we now know the Chinese were making good progressuch superiorhe Chinesene possible answer is that tht Chinese did. in fact, intend to forego MBBM deployment but that the continued deterioration in Sino-Soviet relations and the Soviet intervention in Ciechoskr.akueversal ol this decision sometimether possibilities are that the missile svas not really ready for deployment by the endr thai the Chinese decided to waiternpaliblv TN warhead. In any event, md in view of the unknowns, it seems clear lhat the history of the MRBM program presides us with fewfor judging the probable pace ol other Chinese missile programs or for making any broad lodgment concerning Chinese strategic

Since nothing we have observed in connection svith theuggests that it is Intended for silo deplos--ment. the only means open to tbe Chinese for insuring the survival of some of their missiles is In cnnce.il them In some fashion so they cannot br targeted. One way would be simply to deploy them in inconspicuous field sites. It would also be possible lo conceal missiles and support equipment in structures such as aircralt hangars. In tunnels or caves Such efforts at concealment would degrade tbe reliability and traction time of Ihe svstern and add considerably to operational costs, but it mightrice the Chinese are willing lo pay.

Another possibility would be to build many more launch sites than the number of missiles, moving missile units among sites al frequent intervals Even more thanhis tactic would increase operanug and maintenance costs and reduce the elfectivenevs and readiness of the force. Thus wc believenlikely that tbe Chinese would choose this option

Developments at Shuang<h'eng-tzu

Weumber oi years that China was engaged in the development ol an ICBM system that would be able to provide reasonably good coverage ol the continental US as well as the Soviet Union and other areas. We thought wc had firm evidence ofrogram duringeiiod when constructionaige new launch facility began at the Shuang-ch'eng-tzu rangchead.

At that time we believed that the Chinese intended to begin ICBM fliaht tests shortly, but wc now believe that any early firings from this large launch complex were part of theRBM program rather than work aimed directly at an ICBM. We also think that it was probably used for China's two earth satellite launches.

e have some fairly convincingwhich indicates that the initial flight testarge launch vehicle took place Onhis evidence leads us to conclude that the tiringeduced range flight testultistage, Jiorable liquid-propellant vehicle fired to an impactn tar wrs'ein Ch.na.

e cannot be sure at this point whether the Chinese will conduct any additional in-country reduced-range firings of this largo vehicle or go directly to long-range tests to impact areas outside their national borders. VV'e think it likely, however,ew more reduced-range lests will be conducted.

It may also be usedatellite liunchei. and coulday-load weighing up to several thousand poundsow-earth orbtt.aunch would provide additional important data on theoverall capability and. il successful, would give the Chinese maior propaganda benefits. An approach such tu thn might be politically attractive to tho Chinese and would to some extent parallel the early Soviet ICBM elfort. Indeed, wcurprised ii China did not plan to use this vehicle for bothmissile and space applications.

Tbe Ching-yu Missile System

39that seriously complicate* assessment of tbestatus ot China's ICBM program is our inability to determine the precise nature of the program underway at Chtnti-yti. We believe that the Chint-yu launch facility was activated during tbe falls ofe are reasonably confident that theie had been only one firing from Ching-yi|^

Because tbe Chinese are likely to encounterndement problems common to new proerams andesult of our study of thendrograms, we think it will probabiv take closer to four years ro reach IOC If significant problems occur during Ibght testing, the time required to reach IOC would be commensurateiy longer.

The vehicle bred from Shuang-cheng-tzu on! seems to be the best candidate for an ICBMood capability aaajnst the US. If this pros'esand using the guideline* described above, the earliest IOC date of this system would ber moreear or two later.

These IOC dates wouldear nr two if test difficulties occurred or. as seems to have been the case so far. the program is slosv-pacrd.

The csiderwr thai the Chinese areon silo deselopment Indicates that they decided severalo to deploy matespc missiles in hardened silos, and it now seems likely that initial ICBM depkryrnent will be in silos.

VI. PROJECTED STRATEGIC FORCES A. Introduction

rojecting the size, composition, and capabilities ol Communist China's strategic attack forcesarticularly troublesome task even over the near term and becomes extremely difficult for the.

. Wc know most about China's force ofet mediumtechnical characteristics, production rate, numbers, and location and something about their training. Even here there are uncertainties such as when the Chinese willanker version, what percentage of the force will be equipped with nuclear weapons, where operational units will be based, what their targets and tactics will be. and whether the Chinese will develop an ASM totandoff capability.

n the case of missiles, we start with an uncertain baseline. We believe that the Chinese have deployed then small numbers, but we have not identified deployed units and can only estimate their numbers, mode of deployment, state of readiness, and strategic dispositions. We believe theasr soon willhe end of its flight test phase and that units are being trained, but wC have not identified operational sites under construction and the IOC of the system is uncertain.

ur uncertainty increases sharply when we look at missile systems justor possibly approaching the flight test phase The missile system tested from Ching-yu probably is designed as partegional force directed against Soviet and Mianbut it may have some capability against the continental US.

13S- Our uncertainties become morewhen wc undertake projections of the rate uf deployment of any of the strategic attack systems we believe the Chinese arc developing and. more importantly, projections of the mix of delivery systems which will comprise the force- We have no idea what mix of forces the Chinese will choose, and in some cases the Chinese may not have taken ayet themselves. For example, wheneployment begins wc do not know whether the Chinese will continue to deploy theaintain the existing force, or retire the deployed units. We do not know what the mix will be ol hard and soft sites,

uluiu.

oi permanrnt and field sites. And if the missile tested at Ching-yu is deployed, we do not know what impact that will have on the loice con because we do not know its capabilities

nd we have no experience to go on. We have watched closely while the Soviets tested and deployed aboutand-basedmiisile systems,alf-dozenmissile systems, and several strategic bombers as wellariety of other military systems. Even so, when looking at new Soviet programs we can project with only fairhow fast they arc hkdv tocanon past programs In China, we base not been able to follow and measure

In short, we have nut seen tho Communist Chinese In action and have litde feel for how production and deployment constraints inter -acting with strategic concepts will bein the physical realityeployed strategic attack force.

B. Strotegrc Concepts

hinese strategic concepts will provide the context within which they will allocate resources and plan deployment programs tor their strategic attack forces^ nuclear attack capability in Asia; theedium bombers; thend theheould provide coverage ofportions of all of China's Asian neighbors and most US bases in the Far East, butof the USSH ts limited to the border regions and the Soviet Far East. Thend theould extend coverage of Asia to include must ol Indonesia and India, but their major importance is in sharply increasing coverage of the USSH as lar west as the Ural region.^

We doubt that the Chinese willegional nuclear car^bihty. and Qunas ultimate obsactises rn building aforce in this decade are probabiv foundedesire to erihaoee ils poaibonorld power. Continuing development of Chinas nuclear, missile, and space capabilities will elevate China's statuscientific,and military power in the eyes of most of the svorld, and such status could pro-side substantial leverage for China's political offensives in the underdeveloped world.

The sire of China's continuing invest -merit in the production of nuclear weapons and desetoptneot and deptoymcnt of delivery systems indicates that Peking plans moreoken force for prestige or status, however. It is not content merely to have becomeember of thot the other end of tho spectrum, the achievement ol anythingparity with the US or USSR lies, at best, in the distant future and the most the Chinese can hope to achieve over uV next decade is some degree of deterrence against

china's distance from the us makesredible deterrent against ushowever, and would require icbms or ballistic missile submannes capable of hitting the us homeland. in the meantime, thecount heavily on the existing inhibitions against the use of nuclear weapons, including the weight of world opinion, to deter the us and the ussr from attacking them with these weapons.

their two potential majorthe ussb is probably of greatestconcern to china. the continuingbuildup on both sides nf the borderharsh polemics from moscow andthe past several years indicate thatin ideology and competitionare so strong that relationsand the soviet union probably willcool at best the era ol comradelyofs not likely to beat least for the near future. inclimate, the chinese arc apt to view the soviet union rather than the us or any asian country as their primary' antagonist. the geographic proximity and military power of the soviet union also will influence the chinese in their assessment of the threat.

or china, the grave imptication of the ussr's strategic superiority is that any soviet full-scale nuclear strike, whetheror retaliatory, would result indamage and enormous casualties in china. anduclear capability china has little influence ononflict would be conventional or would escalate to nuclear attacks.

Doctrine for Use

When Ihe Chinese leaders decided some time in theo embarkrogram to develop and produce nuclear weapons and strategic missile deliverythey may have had no very clear idea of just how they would employ these systems. They may not have developed much doctrine beyond the conviction that the possession of such weapons was essential il China were to join the ranks of the leading military powers. We have no way of knowing and, in any case, the subsequent hreak with the Sovietsa major change into whatever strategic equation they were developing.

The only thing the Chinese have since said about their nuclear doctrine is that theyirm no-first-use policy. In the light of the overwhelming nuclear superiority oi the

US and USSR, this isealistic statement of intent. And we think It highly unlikely that Chinese doctrine provides for initiating the use of nuclear weapons against its Asian neighbors. Considering China'sstrength in conventional forces, nuclear strikes against its Asian neighbors would seem unnecessary, would entail great political costs, and would risk retaliation from one of the superpowers.uclear attack on the US or Ihe USSR would invite theof China as an industrial and military power.

e also think it unlikely that Peking would make any crude, direct use of nuclear blackmail against its non-nuclear neighbors. To do so would be against its policy as an-nounccd and practiced up toaneuver would be complicated and perhaps even dangerous because ofreactions by the USSR or the US ina nuclear umbrella lor the non-nuclear powers. Nevertheless, in any confrontanonChina and an Asian neighbor. Chinas nuclear weapons capability would be in the consciousness of tbe other party and might" have some effect on the outcome.

e do no know how the Chinese would proceed should deterrence fail. They presently lack systems which would warn them that strategic missiles had been launched against them (and any such systemew minutes warningovietot this reason, the Chinese cannot launch on wanungbut would have totrategic nuclear attack beforeTheir national command and control systems will have to be devised with this in mind, but we have no evidence of the kind of procedures and systems the Chinese will utilize.

C. Constraints on Future Forces

ver tbe past decade the Chinese Communists haveide variety of programs to develop and produce strategic attack svitems with nuclear warheads They are now movingeriod of deployment which will involve new problems and costs. Thev will still need tn maintainffort looking to improved or more advanced terns This Sectionarictv ofconstraints on deployment of strategic forces: the competition for resources, thennd technical base available to Chinese science and industry, the production capacitsfor nuclear warheads and delivery swlem* and China's ability' to train missile units and construct launch sites.

Tha CompefrfJon for Resources

The human and material resouicesby advanced weapons programi are scarce and expensive in any countrv. but espe-ciaUvhina where the scientific andbases were extremely small pnor to the Communist takeover. The Chinese have demonstrated their willingness to invest scarce resources heavily and continuously in strategic weapon program' WhuV nf cannot quantify the cost of their effort, it is obvious that thev havearge portion of their scientific and technical manpower, advancednnd machinery, skilled labor, andand transportation resources Al Ihe same time they haw been generallynsulating their advanced weapons program from the political ami economic upheavals of the hut decade.

The demand In China for scarce, hlgli-quahtv resources has not been limited to the advanced weapon* program, however. The Chinese have been iimultancouslv ma kmc heavy expenditure* of fesources to equip their conventional forces. expand their industrial base, and increase agricultural output All of these efforts will continue far beyond the period ol this estimate, and whatever the priority accorded strategic attack forces there will be other important claimants for theChina has available.

e have little knossiedge as to how decisions are made in Peking with respect to all Ihe key issues involving the strategic weapons pjogrsm including the establishment of priorities for allocating scarce nationalas between individual sveapon systems and between defense Industries as a'gronp and basic economic developrnent. Mao Tse-tung prolsalJi'inal autbontv in all these matters and the powerful Milrtarv Affairs Commissioney role. But despite the monolithic appearance, there are no doubt difference'* of views svithin the militarvand between some military elements and the state buieaucracv responsible for economic planning and dnetopenent Vested interests in particular programs probably exist svithin the various Re.search Institutes and special ministries involved.

Other Constraints

We haveariety ofconstraints on Chinas strategic forces which Chinese planners are likely to confront during the period of this estimate, including technological and industrial factors,of nuclear weapons, and production capabilities In such fields as liquid and solid missiles, aircraft and submarines- The analyses of these factors did not lead to any conclusion which could be used to quantify limits onprograms.

The balance among resource claimants may shift, of course, with changing military and political relationships in Asia, and the Chinese will continue to have hard choices to make. Should the threat of major conflict with the Soviets increase sharply, for example, we would expect to see greater efforts in support of both strategic and conventional forces at the expense of industrial and agriculturalWe think the Chinese have beenin developing stratcjic weapons long enough to take the realistic view towardforces as but one clement of national power and prestige. While they will probably uccept the drain on other efforts imposed by their ambitious programs for strategic attack forces they arc unlikely to allow this drain to become so heavy that other equallynational programs will bet';!.

If the missiles were kept concealed until placed on alert the reaction times would be about three hours tor erecting, fueling, and aiming the missile

The Chinese may decide that total con-ceaiment of part or all of theirissile force is not practical. Even so thereood chance they will build sites with lew.characteristics or will attempt to make the sites inconspicuous rather thanelaborate soft sites like those the Soviets built for their first strategic missdc systems.

F. Force Structure.hrough

We have used our generalof the present status of China's advanced weapon programs and our estimates of the likely future evolution of tfae individualof China's strategic forces to project three possible force mixes byhe differences between them come from the inter-play of technical achievement and strategic decisions. For example, technical success svith an ICBM may lead the Chinese to decide to divert resources from other programs to hasten deployment In other cases, strategicmay lead the Chinese to emphasizeof one system at the cost of slower development or curtailed deployment of another.

These proiections are only illustrative, and wc would be surprised if China's forces inorrespond in most details to any of them. There are just too many unknowni to predict bow the forces will evolve. The projections do provide ways of thinking about somewhat different courses China may take and our best judgments of what the Chineie are likely to accomplish over the next five years.

Cose A: The first projection assumesorce will receive most of theat least that the Chinese will not succeed in completing development of an intercontinentalthat liquid-propellant missiles will comprise the major elements of the missile forces, with the first solid-propellant missiles entering the force at the end of the period. It seems likely that allissiles will be deployed in soft sites as will the firstRBMs, but we assume that all the missiles deployed in tbe last two or three years of the period of the Estimate wil) lie in silos-

This rmjjection assumes that the missile tested at Cbing-yu would cocmderablyChinas capability to attack the USSB bul would at most providearginal capability against the continental US. It also assumes that ballistic missile submarines will not enter the force byut theorce could be modernized svtth an ASM by that time.

In short, the force presented IneUtneh* conservative protection of present and likely future systems along the lines of evolution nosv evident.
