232. Memorandum From the President’s Assistant for National Security Affairs (Carlucci) to President Reagan1

SUBJECT

  • DOD Report on the SDI Program

At Tab B is the executive summary of the Defense Department’s report on how they would restructure the SDI program, if you were to [Page 856] decide to take advantage of the broad interpretation of the ABM Treaty. The most important of DOD’s conclusions are that:

Under the recommended restructuring of the program, four major system experiments would be conducted over the next three years. The first experiments would occur as early as Fiscal Year 1988. Planning would begin immediately.
Restructuring the program could reduce total costs of research by approximately $3 billion, while increasing confidence in the results of research.
Restructuring would permit a full scale development decision in 1992, and preserve the option to deploy an initial defense in about 1996. It would also delay the need for a decision on withdrawing from the ABM Treaty until about 1996.

The legal analyses of the ABM Treaty that you requested of the State Department will not be complete for another month. Thus, no decisions are necessary at this time. In the meantime, I will have my staff prepare a complete analysis of the DOD report to support your ultimate decision on restructuring the SDI program.

Memorandum From Secretary of Defense Weinberger to President Reagan2

SUBJECT

  • Recommendations for the SDI Program—NSDD 261 (U)

(S) On 17 December,3 I presented to you an approach to the SDI program that would provide the United States with the option to defend itself at the earliest practical opportunity. To preserve this option, we discussed that adequate funding, the broad interpretation of the ABM Treaty, and economical space transportation would be essential. Subsequently, you directed the Department of Defense to provide recommendations for an SDI program under the broad interpretation [Page 857] of the ABM Treaty and increasingly heavy lift space launch capability. These reports are attached to this memorandum.4

(S) The report on developing a heavy lift space launch capability makes it clear that the Nation cannot afford the cost of deploying a strategic defense system with existing U.S. space launch assets. The report, which NASA assisted the Department of Defense in drafting, concludes that a new, low cost, space launch capability is needed to satisfy growing NASA and DoD space launch requirements, as well as those of SDI.

(S) The report on the SDI program concludes that restructuring the program under the broad interpretation of the ABM Treaty will dramatically increase program efficiency and reduce costs by approximately $3 billion. Most significantly, if adequate funding is provided, this restructuring will preserve the option to deploy an initial defense system in 1994 and, thereby, will enhance the prospects for serious negotiation on arms reductions with the Soviet Union. The realization of these benefits, however, is contingent upon the immediate authorization to restructure the SDI program to take advantage of our legal right to conduct research and development under the broad interpretation of the ABM Treaty.

(S) While the report on restructuring the SDI program makes a compelling technical argument for adopting the broad interpretation of the ABM Treaty, I believe that political considerations will prove to be critical, especially the issue of when we will have to withdraw from the ABM Treaty. If the SDI program continues to be restricted by an incorrect reading of the ABM Treaty, it will be necessary to withdraw from the Treaty at the latest by 1992, or possibly as early as 1989, in order to continue useful research and testing that could lead to deployment. These activities are necessary to demonstrate persuasively the feasibility of strategic defenses before the nation commits itself to the full-scale engineering development of such a system and certainly before its actual deployment.

(S) If we had to make a decision to withdraw from the ABM Treaty in order to continue the research phase of the SDI program, it would be tantamount to asking those with an attachment to the existing strategic and arms control arrangement to abandon the Treaty before the program had demonstrated persuasively its ability to provide an effective defense. Since this probably would be more than the political traffic could bear, it would spell the end of the SDI program. The program would forever be caught up in the catch–22 of a national reluctance to jettison the ABM Treaty without clear assurance that SDI could take its [Page 858] place, and SDI’s inability to provide that assurance without first jettisoning the ABM Treaty.

(S) However, a program restructured under the broad interpretation of the Treaty would avoid this political catch–22. Such a program would allow us to complete the entire research phase of the SDI program, as well as the full scale engineering development phase of the program, before we make the decision to withdraw from the ABM Treaty and deploy a strategic defense. This approach has the advantage of allowing a future President and Congress to make these important and politically difficult decisions with proof in hand that effective defenses are technically feasible.

(S) Finally, while the broad interpretation of the ABM Treaty and the development of a national heavy lift launch capability are essential to a successful SDI program, full funding for the program is of equal importance. The gains which are possible by restructuring the SDI program to be consistent with the broad interpretation of the ABM Treaty are predicated on the program receiving adequate funding. The SDI program has shouldered the burden of Congressional funding cuts since 1984, when you sent the first SDI budget request to the Congress. These cuts were particularly severe last year and what we have seen so far indicates that the program will have to weather similarly heavy budget storms this year. This is why it is so important that this Administration make a concerted effort over the next several months to secure sufficient funding to guarantee an effective SDI program. As always, I will assist you in this every way I can.

EXECUTIVE SUMMARY (U)

INTRODUCTION (U)

(S) On 18 February 1987, the President directed the Secretary of Defense to provide a plan for restructuring the Strategic Defense Initiative (SDI) program in the event the President authorizes the use [Page 859] of the broad interpretation of the ABM Treaty. The Secretary of Defense was directed to include a description of the first planning activities and tests which would require the broad interpretation and an assessment of the impact of not being permitted to restructure the program. In order to develop a recommended program, the Department of Defense assumed that this program would remain within currently projected budgets, would maintain a balance among technologies, and would support a Presidential decision on the deployment of defenses as soon as possible. For the purpose of evaluating experiments in the restructured program, it also was assumed that advanced kinetic energy technologies in the SDI program are based on principles other than those that governed defensive systems in 1972 and that, therefore, they could be fully tested and developed under the broad interpretation of the ABM Treaty. In view of the limited time available to conduct this analysis, the programmatic and budgetary details of the restructured program presented in this report are approximate and will have to be refined in more formal reviews.

RECOMMENDED RESTRUCTURED PROGRAM (U)

(S) The current research program has focused on individual technologies and components, in part because the restrictive interpretation of the ABM Treaty prevents the development and testing of devices that have full defense capability and integrated tests using these devices. Due to the significant progress that has been made to date, the SDI program is ideally positioned to integrate the basic elements of a strategic defense system, such as sensors and weapons, in realistic tests which will more fully validate defensive concepts. Under the recommended restructured program, four major system exploration experiments will be conducted over the next three years. These experiments are designed to identify early in the program any unexpected technical issues and to increase confidence in the feasibility of strategic defenses. The first experiments in this restructured program will occur as early as Fiscal Year 1988. Planning activities to support this challenging schedule must begin immediately. In the current program, the SDI effort will remain limited to individual experiments which do not validate technologies fully and which do not establish as high a level of confidence in the feasibility of defenses based on these technologies.

(S) In addition to the major experiments which explore the issues of system integration, the development of individual technologies will also benefit from the broad interpretation. Restructuring to take advantage of the broad interpretation more than pays for itself by eliminating repeated flight tests of individual technologies. Although some reprogramming of funds will be necessary within the SDI budget over the next five years, this amount is a fraction of the reallocation caused annually within the program by Congressional cuts.

IMPLICATIONS OF RESTRUCTURING (U)

(S) The implications of restructuring the SDI program are clear and dramatic. The recommended program will allow for more efficient use of projected budgets and could reduce the total costs of research by approximately $3 billion dollars. Under this program, confidence in defense feasibility will increase much faster, and the program management uncertainty caused by the inherently ambiguous restrictive interpretation will be reduced substantially. Additionally, restructuring under the broad interpretation of the ABM Treaty allows the President to defer withdrawal from the ABM Treaty until after full-scale engineering development is completed and just prior to actual deployment. A restructured SDI program will permit a full-scale engineering development decision as early as 1992 and preserve the option to deploy an initial defense in about 1996 that will provide an effective defense when fully deployed. Conversely, if the program were not authorized to use the broad interpretation of the ABM Treaty, the United States would have to withdraw from the Treaty about 1992 in order to permit the pre-FSED phase of the program to be completed (FSED could begin at the time of Treaty withdrawal, but at a lower level of confidence in defense feasibility). In fact, because of possible political inhibitions against allocating long-lead funding to prepare for non-Treaty compliant experiments, this issue may have to be faced as early as FY1989 if the program continues to adhere to the restrictive interpretation. A 1992 withdrawal from the ABM Treaty would delay a decision to enter full-scale engineering development until at least 1994 (assuming a requirement for a high level of confidence when entering FSED) and the Nation’s initial deployment option would slip two years to approximately 1998, allowing even further evolution in Soviet offensive and defensive threats.

AUTHORITY TO RESTRUCTURE (U)

(S) The restrictive interpretation of the ABM Treaty has already caused the SDI program to sacrifice program effectiveness and highly significant experimental options. Any delay beyond May 1987 in adopting the broad interpretation of the ABM Treaty will have increasingly detrimental consequences for the SDI program including higher costs, further delays, and the loss of deployment options. A delay of one year in receiving authorization to restructure the program according to the broad interpretation would, for example, delay the option to deploy an initial defense system at least a year and a half until FY 1997 and sacrifice substantial cost savings.
