195. Memorandum From the Special Advisor to the President and Secretary of State on Arms Control Matters (Nitze) to Secretary of State Shultz1

Mr. Secretary:

As we have discussed previously, in order to achieve a START deal, I believe we must deal concurrently with the Soviets on space/defense. As to the latter, we must come to an understanding with the Soviets on what is—and what, with respect to systems based on “other physical principles,” is to be—permitted and not permitted under the ABM Treaty. In pursuing the permitted/non-permitted activities issue with the Soviets, we will wish to preserve our SDI research program.

Accordingly, I have developed a “think piece” which might deal with permitted/prohibited activities. I have circulated to a number of people in the Administration in an effort to refine the paper; most have been helpful and the attached paper represents this refinement.

It will not be surprising to you that the comments fall into two basic categories: (1) from those who wished to work constructively on the problem, and (2) those in OSD who wished to block any solution to the problem.

This is one of the issues which we need to discuss when you return.2

Draft Paper Prepared by the Special Advisor to the President and the Secretary of State for Arms Control Matters (Nitze) to Secretary of State Shultz4

Draft #II
(As modified)

A POSSIBLE APPROACH TO WHAT TESTING THE ABM TREATY PERMITS AND DOES NOT PERMIT

Should the Soviets indicate an interest in working out an NST deal of interest to the U.S., what kind of an NST package would be of interest to us and be potentially negotiable?

Our interest would be in stabilizing START and INF reductions. The Soviet interest appears to be focused on a time period involving non-withdrawal from the ABM Treaty and strict adherence to an agreed interpretation of its terms.

We know pretty well what we want with respect to START and INF. The most difficult and controversial Space/Defense issue within the Executive Branch is the question of what we could live with in the way of an agreed interpretation of what testing of components of systems based upon “other physical principles” (OPP) is permitted and not permitted by the ABM Treaty. The currently agreed interpretation of the Treaty in the U.S. Executive Branch includes the view that Article V does not apply to testing of components based on OPP as addressed in Agreed Statement D.

As a possible approach, the concept in Agreed Statement D of consultation under Article XIII, combined with the concept in Article VI, could logically be applied to “components” based on OPP capable of substituting for ABM missiles, launchers, or radars. Article VI explicitly applies to missiles, launchers, and radars that are not Article II “components”; specifically, Article VI(a) prohibits giving “missiles, launchers, or radars, other than ABM interceptor missiles, ABM launchers, or ABM radars” ABM capabilities or testing them in an ABM mode. It would be consistent with the concept of Agreed Statement D and of Article VI, after consultation under Article XIII, to extend the coverage of Article VI to devices based on OPP and potentially capable of substituting for ABM missiles, launchers, or radars.

[Page 685]

A procedure which could lead to a mutually agreeable solution to the permitted/non-permitted testing of components based upon OPP issue might be found along the following lines:

The sides would confirm that it would be consistent with the concept of Agreed Statement D and of Article VI of the ABM Treaty to interpret Article VI to provide that neither side will give systems or components other than those defined in Articles I and II an ABM capability or test them in an ABM mode.

The sides would specifically agree that “components” based upon OPP and potentially capable of substituting for ABM components as defined in Article II are subject to the limitation in Article VI.
It would then be necessary for the sides to arrive at a mutual understanding as to what are such components based upon OPP that have the potential to substitute for ABM components as defined in Article II if tested in an ABM mode and what the term “testing in an ABM mode” means with respect to such potential components based upon OPP.

The U.S. Government, before offering to negotiate such a mutual understanding, would have had to arrive at a judgment as to the answers to two questions implied by the above.

a)
What could we now agree would constitute components based upon OPP potentially capable of substituting for ABM components as defined in Article II?
b)
What could we now agree would be verifiable criteria with respect to determining whether such potential ABM components are tested in an ABM mode?

With respect to question a) above, a number of possible examples come to mind:

i.
Space-based continuous lasers with power greater than 10n watts or space-based pulsed lasers with energy greater than 10p joules per pulse.
ii.
Ground-based continuous lasers with power greater than 10n+y watts or ground-based pulsed lasers with energy greater than 10p+z joules per pulse.
iii.
Space-based mirrors associated with directed energy systems with an effective diameter greater than “D” or ground-based mirrors with a diameter greater than “D”+X.
iv.
Other space-based and ground-based directed energy weapons with comparable potential effectiveness.
v.
Space-based kinetic energy devices capable of accelerating to a relative velocity greater than 3 kms per second.

With respect to question b) above, the sides would use an appropriate modification of the definition of “tested in an ABM mode” as [Page 686] it was defined in the 1978 Agreed Statement to the Treaty (attached).5 In addition, we would seek reaffirmation: (1) that “subcomponents” or devices that do not have the potential for component-level capabilities as defined above may be tested without limitation; (2) that testing against an object in orbit in space is not a test in an ABM mode; and (3) that tests in space from fixed, land-based test ranges not “in an ABM mode” are permitted, but if these tasks are “in an ABM mode” they would cause the components capable of substituting for ABM components involved in the test to become “ABM components” subject to all of the treaty’s limitations on such components.
