THE PROBLEM

To assess the current state of Communist China's nuclear weapons and missile program and, insofar as possible, estimate the future course and size of that program.

NOTE

Although we haveonsiderable amount ofood deal of overhead photography) in the past year or so, there remain serious gaps in our information and we are therefore not able to judge the present state or to project the future development of the Chinese program with any high degree ofThe specific judgments in this paper should be read in the light of this general caution.

CONCLUSIONS

A. Communist China's first nuclear test on4 was of an implosion fission devices the fissionable material

|Wc cannot estimate with confidence its weight or dimensions but believe it was relatively large and heavy. The most likely source ofas uranium first brought to partial enrichment in the gaseous diffusion facility at Lan-chou and then further enriched by the electromagnetic process. We cannot, however, rule out the possibility tliatas of Soviet or other non-Chinese origin though we believe this to be highly unlikely.

DISCUSSION

The Chinese Communist detonation al Lop Nor onramatic incident in PeipingS determined effort toodern nuclear power. During the past year oi so theie hasubstantial increase in our information on the Chinese advanced weapons programs,ood deal of overhead photography. We believe that the Chinese had at least planned or begun construction on virtually al) their major advanced weapons facilitieshen they wci'c stillroad range of Soviet assistance, Wc do not know tbe precise extent of involvement ol the Soviets In all these projects, but there is good evidence that tltey provided the Chinese with considerable technical and material assistance. We believe this included an experimental nuclear reactor, facilities for processing uranium, some equipmentaseous diffusion plant, assistance inissile test range, the equipmentewir missile sites, andew surface-to-surfaceAlthough much of the progress wc have observed to date results from earlier Soviet help, it is difficult to judge how much progress was achieved through Chinese efforts, aided by the considerable amount of information on Free World nuclear developments that is available in open literature.

Communist China is almost certainlyarger proportion of its scientific and technical resources to the development of advanced weapons than any other nation. Althoughesolute diversion of resources enhances the prospect for successes in someorced-draft effort restingery limited scientific, technological, and industrial base is susceptible to numerous difficulties. Thus the Chinese are likely to he forced to some expedients and make-shift adaptations for which US, Soviet, British, and French experience is no precedent, and which will accordingly be hard for us to detect or predict.

Furthermore it Is likely thai tbe Chinese woukl have been conservative in their desiftns and dimensions in order lo minimize (lie chances of failure in their first testj-

The Source of IheWe cannot identity the source ofsed by tbe Chinese in their first nuclear test. It could haveobtainedoreign source, but we behave that the most likely .tourer is ChineseAnalysis of lite nuclear debris from the Chinese test sbuws that the ratios of uranium botopes in tlie Chinese material dirVr (rum those of the highly enriched uranium produced by the USSR and the US since around the. We have been informed by the UK (bat all theiras ratios of uranium isotope* different from those of tbe Chinese test. All US highlyroduued foi export under bilateral agreements has ratios of uranium Isotopes diflerent from those of the Chineve device In addition, the US-UK-cxportcd material is under continuing safeguard* Including fnspec-tion and accounting which give reasonable assurance that kilogram quantitiesould not have been secretly diverted. The only highlyhich we know to be in French possession is of US origin and has isotope ratios different from the materia) used in the Chineseome uf the Sovieturanium produced earlier than the, however, may havethat used by tbe Oiiinesr.

We cannot therefore, rule out tbe possibility of Soviet origin on purely technical grounds- We believe it catremeh. unlikely that the Sovietsor the teal alter mid-IflfO, but tbey could liavc dune >i> Miiiietiine- beforeeriod of <ri*is In Sino-Soviet relations. If so. It Is difficult to explain why more than four years elapsed before tbe first test. To explain the delay on technical gruumls would ine.au that the Chinese are iar more retarded in iheir nuclear technology than we believe is the case. Another explanation wouldeliberate decision In delay. Tbe Chinese, knowingong hiatus between the first and sulaequenf tests would reveal to the world thai China wasuclear power In its own right, might have refrained from using the Soviet-supplied material until they cnuld follow up quickly wilh further tests using domestically produced matiiial Tliis line of reasoning would lead, therefore, to tbe conclusion thai the Chinese are now (Widen! of ibeir own production capability. In addition, the cirointstances andhe developing Sino-Soviet dispute suggests that tlie Soviets did not supply. Sudi rernarks as Soviet officials havr made on tbe matter are contradictory and whollyWe know, however,oviet refusal ino provide tbc Chinese with further nuclear weiqioii technology was one of tlie critical issues in the

dispute. The Chinese have also charged in their polemics that the Soviets9 refused toample atomic weapon. In the light of all thesewe believe that the Soviets did not provideor CHlC-1.

It Is highly unlikely that the Chinese have developed some third process The gas centrifuge process has never been developed beyond tbe experimental stage In the Free World.

There is no persuasive evidence thai the Soviets have produced gas centrifuges in significant numbers and none that tliey have given any to the Chinese. We do not believe that the Chinese have attained the manufacturing capability and technology required for domestic production of tlie necessary large numbers of suitable centrifuges.

Electromagnetic technology, on Ihe other hand, is well developed and almost certainly within the knowledge and competence of the Chinese. An all-electromagnetic process would produce isotope ratios different from thoseinombuialion ol the gaseous diffusion process for partial enrichment and tlie electromagnetic process lorupping-oH" could have produced material like that used in the Chinese device. We incline to tbe view, dierefore, thatsed in China's first nuclear detonation was produced through low enrichment by gaseous diffusion at Lanchou, with final enrichment by electromagnetic separation.

An analysis of the buildings, physical lay-out- and power available at Lanchou suggests that the Chinese could have both gaseous diffusion andequipment there. It is also possible that partial enrichment was done at Lanchou and the electromagneticwas done at some other location. Suitable photography is available for aboutercent of China and all the areas which show the requisite high security precautions plus available buildings and power have been examined. No electromagnetic facility has been identified but we estimate thatlant could exist in the other known atomic energy sites. It is further possible that there is an electromagnetic facility in some part of China not yet covered by usable photography.

Air-to-Surface Missiles. Wc believe the Chinese Communists have no air-to-surface missile (ASM) capability at this time. While some of the original facilities at SCTMTR airfield suggest that im ASM program was at one time contemplated, no more lecent indications ofrogram have been identified and wc believe that other higher priority weapons programs make such an ef&fft unlikely.

Air-iO-Afr Missiles. Tlie Chinese Communists mayimited number of air-to-air guided missiles (AAM) for their fighter aircraft. While wc have no direct evidence that the Soviets supplied any, aircraft have been observed with equipment suitable for carrying such missiles. We have no persuasive evidence that the Chinese are producing AAMs hut we believe it within their capabilities to produce copies of Soviet missiles or US infrared Sidewinders. Such US missiles were captured by the Chinese at the time of the Taiwan Strait crisis

Wc have no evidence as to what missile the Chinese may be planning to put in this submarine or as to whether the Soviets gave them assistance in this respect. Presumably the Chinese are aiming at thee have no evidence that the Chinese are now constructing any more of this type submarine, and it would be at least several years before any units could be operational with Chinese-produced missiles. The Chinese Communists might be greatly attracted to the developmentissile submarine force which could pose atimited nuclear threat to targets in the US.

Coastal Defense Missiles and Guided Missile Patrol Boats. Wc have fairly good evidence that th* Soviets in9 provided the Chinese with some cruise missilesange of. and whichigh explosive warhead. Since that time the Chinese have maintained an apparently active test range and development center for coastal defense cruise-type missiles at Lien-shan on tbe Culf of Liaotung. The only other cruise missile site we have identified in China is near Daircn. Wo cannot be certain however that it is operational. Although we have no evidence of Chinese production of cruise missiles, the LJen-shan facility indicates the Chinese are interested. They probably could produceeapon system without much difficulty.

IV. PROJECTIONS FOR THE LONGER TERM

With our knowledge of Communist China's advanced weapons program being as sketchy and maoVpiate as it is, any longer term estimates must be even more tentative than those made above. The next decade could bring important, even radical, changes to China and to the state of internalioiml relations. It is likely that many of the lop leaders will have passed from the scene, and what this might mean for Peiping'? foreign, military, and domestic policies is un-piedlctable. There remains the profound question of tlie outcome of the race between population growth and food supply innd. indeed, the propoition of China's scientific, leelinical, and industrial resources and energies that tbe regime sees fit to devote to advanced weapons and other military program- will have an important bearing on this question.

Tbe Chinese probably will be able to pnrcred with eiperimeirJattori on various types of nucleai warheads and missile systems However, tliere will be limitations in the supply of fissionableyriad of technologicaland an rnormmi* economic burden. An intermediate range missile0 miles) would not bring within range many additional targets (except possibly in the USSIt) likely to be of interest to l'eiplng and the Chinese may try lo jump to an mlercoittJiiental capability. Even If developmenl liaseen started, we dolieve they could have an operational ICDM system until

If the Chinese Communists decide toassive effort toweapons pre-grants. irrespective of the cost to uthei partsthe economy, they probably will be able to carry forward many of the weapons programs considered in this estimate However, pressing all those programsuccessful conclusion willormidable task and tbc Chinese may be forced to accept changes and delays It is ptuhably within Chinese capabilities lo carry out at least those programs with the highest priority, eg. Ihe nuclear weapons, MKKM. and SAM programs.
