80. Memorandum From the Deputy Secretary of State (Rush) to the Acting Secretary of Defense (Clements)1 2
- U.S. Responses to Soviet Anti-Satellite Activities
Thanks very much for sending me the recent interagency study of U.S. responses to Soviet anti-satellite activities. I have reviewed this study and your memoranda directing certain actions related to a study of the vulnerability of U.S. space systems and to development of a plan for an anti-satellite technology program.
I recognize the reasons for your concern and believe it desirable that we examine carefully, as you have directed, the possible vulnerability of our space systems to Soviet anti-satellite action and that we consider what steps may be necessary with respect to our own anti-satellite capacity. I should like to note, however, that there are important political and other considerations which may affect decisions on U.S. anti-satellite efforts and which should be taken into account.
Any new U.S. efforts relating to anti-satellite activities, for example, are likely to become public knowledge and may become a subject of domestic controversy and stir foreign concern and reaction. A question may well be raised as to U.S. intentions since we have recently concluded a permanent treaty and an interim agreement with the U.S.S.R. which ban interference with each other’s national technical means of verification. Furthermore, there is the basic issue as to whether a new U.S. anti-satellite program (presumably non-nuclear) is needed on strictly military grounds.[Page 2]
I do not wish to imply that we should not proceed merely because we might encounter domestic or Soviet objection. I appreciate, of course, that the Soviets have proceeded with their program despite our possible concerns in light of the SALT agreements. I strongly feel, however, that before we go much farther down this road, we should have a thorough review of the issues involved, on an interagency basis and at a high level. I suggest that an early meeting of the DPRC be convened for this purpose.
