68. Information Memorandum From the Assistant Secretary of State for Politico-Military Affairs (Holmes) to Secretary of State Shultz1

SUBJECT

  • NSPG Meeting at 2:00 p.m., Monday, October 7, 1985

Monday’s NSPG will be devoted to an Intelligence Community codeword briefing on Soviet strategic defenses. It is our understanding that the briefing will be identical to the one given on the Hill on Thursday2 prior to the public release of the pamphlet “Soviet Strategic Defense Programs.” (Tab 3)3

As indicated in the attached INR memos (Tabs 1 and 2), the Soviets have been researching laser, particle beam, radio frequency, and kinetic energy technology for the last 20 years. Although we cannot precisely identify the size and scope of Soviet research efforts in technologies applicable to ballistic missile defense, there are SDI-type technologies in which Soviet research is progressing and in which we can identify or hypothesize links to BMD.

In INR’s view, the Soviets are ahead of the U.S. in some basic SDI-related technologies, but well behind in the key supporting technologies of any SDI weapons system (e.g., electronics and computer software). The area where the Soviets are probably furthest along is ground-based lasers.

Points to Raise

You may want to solicit CIA’s estimate of who is ahead in the area of space-based strategic defense. What are the strengths and weaknesses of the Soviet program relative to the U.S. program?
What are Intelligence Community projections for the Soviet program five or ten years from now? What are IC estimates on who will be ahead then?
The IC has stressed the difficulty of obtaining information on Soviet programs. What are the possibilities of being able to monitor the Soviet program in the future?

  • Advanced-Technology Weapons and Soviet Strategic Defense

Recent Soviet statements have led some to believe that they are exploring our receptivity to a proposal that would limit SDI deployment, but would permit some types of research. We have assumed their motivation for such an approach would be to allow some US research as a “face-saving” way for the US to agree to an SDI limit. Actually, the Soviet motivation in allowing some research may be to permit their own programs to go ahead. This memorandum briefly sketches what we know about the Soviet programs.

The Soviets have been working with directed-energy (laser, particle beam, and radiofrequency) and kinetic-energy technologies for about the last twenty years. A portion of those technologies is applicable to BMD, and part of the Soviet effort is believed to be focused on that goal.

We cannot precisely identify the size and scope of Soviet research efforts in these areas, nor can we pinpoint the status and goals of any related weapon development programs. These technologies can have both weapon and nonweapon applications, making it difficult to determine the purpose of any detected research effort. These limitations, in turn, would make it difficult to monitor any future restrictions on research.

Using Kvitsinskiy’s terminology, some Soviet advanced-technology research could be construed as “fundamental” or “purely scientific.” But in at least one case, ground-based lasers, the “purposeful and directed” label seems more appropriate. Intelligence indicates that the Soviets are interested in ground-based laser BMD, and at least one Soviet facility is judged to house a high-energy laser that might support BMD testing. To protect their ground-based laser research from restrictions on advanced-technology strategic defenses, the Soviets could attempt to [Page 234] exempt ground-based weapons from such restrictions, or could simply try arguing that the research in question is only “fundamental.”

High-Energy Lasers: In a laser weapon, an intense beam of light is aimed at a target by an optical device. The target is damaged by explosive shock, heating, melting, or vaporizing.

The Soviets have a military-sponsored program to develop high-energy laser weapons. [less than 1 line not declassified] the existence of a Soviet project to develop a ground-based laser weapon for terminal defense against ballistic missile warheads. While there are doubts about the possibility of using ground-based lasers for BMD, the Soviets could conduct feasibility tests during this decade, perhaps using the high-energy laser at Sary Shagan. If that proved successful, a prototype ground-based weapon could be tested in the early 1990s. A fully operational weapon is unlikely before 2000.

The Soviets may also have plans for a space-based laser. While ASAT would be the probable initial application of such a weapon, subsequent BMD use is possible. In the 1970s, this “project” was reportedly in its early stages. We have had no evidence of its status since then, and do not know where the effort stands. To develop a space-based BMD laser, the Soviets would have to achieve a number of major technological advances. The Intelligence Community estimates that, even if this can be accomplished, no prototype will be available before the mid-1990s, and no operational system before 2000.

Particle Beam Weapons (PBWs): In PBWs, intense beams of electrons, protons, or atoms are produced by a high-energy accelerator and aimed at a target by magnets. Damage results from thermal, mechanical, and secondary radiation (nuclear or X-ray) effects.

Our intelligence on Soviet work on PBW technologies is limited. We believe they are conducting research under military sponsorship for the purpose of acquiring the ability to develop PBWs. We have no evidence that they actually are developing such weapons. We lack firm knowledge as to the size or scope of their efforts, and do not know whether it is comparable in scale to their laser program. We believe they are capable of testing the feasibility of some PBW concepts but not others. It is not clear whether they have actually succeeded in demonstrating the feasibility of any. Indeed, it is not clear that PBWs are technically feasible at all.

The Intelligence Community believes the Soviets are at least 10–15 years away from testing any long-range, ground-based particle beam weapon for terminal BMD. A prototype space-based PBW, for damaging ballistic missile electronics, is also at least 10–15 years away, assuming the Soviets pursue development of such a system. Eventually, PBWs might be refined for use in RV or booster destruction.

[Page 235]

Radiofrequency (RF) Damage Weapons: In an RF weapon, electromagnetic radiation is aimed at a target by an antenna. Electronic components or the target structure may be destroyed by circuit overloading or thermal effects. The Soviets have conducted research in the use of strong RF signals, which have the potential to interfere with or destroy components of missiles and warheads. We do not know if a Soviet RF weapon program exists. If they were to pursue such a program, the Soviets probably could develop an RF weapon which could destroy the unprotected electronics of missiles at a range of up to one kilometer. A prototype capable of doing this over ranges of tens of kilometers could be possible by the late 1980s.

Hypervelocity Kinetic-Energy Weapons: In a hypervelocity kinetic-energy weapon, a mass ranging from a stream of microscopic particles to a solid projectile is directed at a target. Impact causes melting, vaporization, and chemical decomposition.

While we know that the Soviets have conducted research and development on kinetic-energy technologies with potential applications for strategic weapons, we have no information indicating that they intend to develop long-range kinetic-energy weapons. The Intelligence Community estimates the probability of a Soviet prototype for such a weapon in the next ten years to be very low.

SUBJECT

  • How the Soviets Look at SDI: Your Query

The Soviets probably do not know what they “really think” about SDI, and will not know for some time. They have called it destabilizing, a violation of the ABM Treaty, and part of a US attempt to gain superiority. At the same time, the Soviets have been researching SDI-type technologies for about 20 years. They currently are behind the US in such key supporting technologies as electronics and computer software. They are ahead of the US in some basic weapon-related technologies [Page 236] and behind in others, but probably believe the US soon will pull well ahead.

In response to SDI’s deployment, the Soviets could bolster their offensive forces, move to a counter-city strategy, or deploy nationwide BMD of their own. For the near-term they appear to have decided against moving toward “defense dominance.” A major reason for this probably is that, compared to the present situation, effective US defenses—no matter how the USSR might respond—would make Soviet deterrence of the US much more uncertain, and clearly more expensive.

You wondered the other day at the Casey6 briefing how the Soviets view SDI. This is a distillation of what the Soviets say about SDI, what research and development they are undertaking in SDI-type systems, and our assessment of what the Soviets really think about SDI.

Soviet Pronouncements on SDI

In public and at Geneva, the Soviets have characterized SDI as destabilizing and a violation of the ABM Treaty. They have taken the view that SDI will only provoke Soviet counter-measures, and thus will result not in greater security but in increased military expenditures and levels of arms. Gorbachev has also warned that SDI will cause a breakdown of the Geneva arms control process. In essence, the US and USSR have exchanged scripts—the Soviets are making much the same arguments about BMD now that the US made in the 1960s.

The Soviets profess to view SDI as part of an overall US first strike strategy aimed at obtaining strategic superiority. They consider new US offensive weapons—MX, Trident II, cruise missiles, and the Pershing II—as intended to destroy as many Soviet offensive weapons as possible in a first strike, with SDI cleaning up the remaining Soviet weapons. (This is essentially a mirror-image of the Soviets’ own strategic concept.) Since, the Soviets say, SDI cannot provide a leakproof defense against a large, coordinated strike, its only logical role is against a “ragged retaliation.”

Soviet SDI-Type Research and Development

The Soviets have been researching laser, particle beam, radiofrequency, and kinetic-energy technology for about the last 20 years. We cannot precisely identify the size and scope of Soviet research efforts in technologies applicable to BMD, nor can we pinpoint the status and goals of any related weapon development programs. These technologies can have both weapon and nonweapon applications, making it difficult to determine precisely the purpose of Soviet R&D efforts. Nevertheless, there are SDI-type technologies in which Soviet research [Page 237] is progressing, and in which we can identify or hypothesize links to BMD.

High Energy Lasers. The Soviets have a military sponsored program to develop high-energy laser weapons, including a ground-based weapon for terminal BMD. A facility at Sary Shagan is believed to house a high-energy laser which may have a BMD application. The Soviets may also have a project for a space-based laser—while ASAT would be the probable initial use for such a weapon, subsequent BMD use is possible.

Particle Beam Weapons (PBWs). We have limited evidence on Soviet PBW research. While we believe they are conducting research under military sponsorship in an attempt to acquire the ability to develop PBWs, we have no evidence that they actually are developing weapons. We believe they are capable of testing the feasibility of some PBW concepts, but not others, and it is not clear whether they have succeeded in demonstrating the feasibility of any.

Radiofrequency (RF) and Kinetic-Energy Weapons. The Soviets have conducted research in the use of strong RF signals, which have the potential to interfere with or destroy missile components, and on kinetic-energy technologies with potential BMD applications. But we do not know the extent, if any, of Soviet RF and kinetic energy weapons programs.

Who’s Ahead? We don’t know where the Soviets currently think they stand vis-a-vis the US in SDI-type technologies. In our view, they are ahead of the US in some basic technologies and behind in others, but well behind in the key supporting technologies of any SDI weapons system (e.g., electronics and computer software). Wherever they think they stand now, the Soviets probably believe the US soon will be well ahead.

What Do They Really Think?: An Assessment

Even the Soviets probably don’t know what they “really think” about SDI, and are unlikely to know for some time. A meaningful Soviet evaluation of SDI, and of the USSR’s ultimate position toward it, will depend on a number of factors, many of which—such as the effectiveness of future US and Soviet defenses and countermeasures, as well as the costs involved—are not known at this time. We can, however, illuminate the key doctrinal factors likely to affect the Soviet view of SDI, based on Soviet military writings and programs, and the USSR’s positions in past arms control fora.

SDI’s Threat. An effective US SDI system would make the Soviets’ counterforce strikes less effective. In order to continue their present strategy of deterrence through war-fighting, the Soviets would have to bolster their counterforce capability to penetrate US defenses, and deploy additional defenses of their own to compensate for their lessened counterforce capability.

[Page 238]

Alternatively, the Soviets could move to a counter-city strategy, which is easier for the attacker and very demanding for the defender (only one warhead would have to penetrate the defenses to destroy a city). This strategy would require many of the same offensive force improvements as war-fighting, but would be less costly. Some increases in defenses also probably would be required, if only to complicate US attack planning.

SDI’s Promise. The Soviets could choose to respond to SDI by deploying missile defenses of their own. Indeed, “defense of the homeland” is the keystone of Soviet planning. An effective nationwide BMD system is the most important defensive “missing link” in their current strategy, which explains why the Soviets have been conducting their own SDI-type research.

However, the Soviets do not have a fixation on defense for its own sake. While they clearly would prefer a world in which only the USSR had effective defenses, the Soviets almost certainly regard this as unrealistic since the US would respond by deploying defenses of its own. As pragmatists, they would therefore weigh the risks as well as the benefits of competing with the US in an SDI race.

The Soviet SDI Dilemma. Would the Soviets prefer a situation in which both sides have nationwide BMD, or in which there are no such defenses? For the near term—and neither we nor the Soviets know what they’ll decide over the long term—the Soviets apparently have chosen the latter. They may have taken this stance for some of the same reasons they signed the ABM Treaty in 1972: they perceived the US as having a technological lead, and decided that it was more feasible to limit damage to the USSR by offensive counterforce strikes (which could be hindered relatively easily by US defenses) than by nationwide BMD (which was essentially impossible).

The Soviets have political reasons for opposing SDI; it plays well as part of the “peace” campaign, since many see SDI as a major reversal of US strategy and a threat to arms control. Nonetheless, their position that SDI is dangerous and destabilizing also is due to the fact that, compared to the present strategic environment, effective US defenses—no matter how the USSR responds—would make Soviet deterrence of the US much more uncertain, and clearly more expensive to attain. Today, the Soviets can be highly confident that their ballistic missiles will reach their targets; US defenses would make this much more uncertain. At the same time, the Soviets would have crucial doubts about the inherent effectiveness of their own defenses which would be compounded by US offensive countermeasures. The Soviets would be reticent to give up a known situation, in which they probably believe they are doing well, for an unknown “defense dominant” world of increased strategic uncertainty.
