132. Telegram From Secretary of State Vance to the Department of State1
Secto 8019/10615. Subject: Vance-Gromyko Meeting Morning Session July 12.
Secretary Vance made a formal presentation on SALT at the opening session, the text of which follows below. Gromyko asked for a recess until 3:30 this afternoon to consider the new U.S. proposal. We will meet with the Soviet delegation again at that time. Quote.
This morning I propose that we focus on one of the most important issues remaining to be resolved in the agreement: limitations on the in[Page 426]troduction of new types of strategic missiles and on modernization of existing types of strategic missiles.
I would first like to review where we stand on the issues of new types of ICBMs and SLBMs and of modernization of existing types.
In previous discussions we have proposed a ban on testing and deployment of new types of ICBMs in the protocol. This would prohibit introduction of new types of ICBMs through 1980 while we discuss how to deal with this issue in SALT III.
We have also indicated that we could accept a ban on testing and deployment of new types of ICBMs through 1985, except that either side could test and deploy one new ICBM, MIRVed, or non-MIRVed. This would permit you to go ahead with the new, single RV ICBM, which fits your force structure, and would permit us to proceed with a new MIRVed ICBM, which would fit into our force structure. This would provide for equality and equal security on both sides.
Either of these proposals would represent a satisfactory solution of the ICBM new types issue.
In the context of a protocol ban on new types of ICBMs, we could agree to a ban on new types of SLBMs, allowing for continued testing and deployment of Trident I and for the SS–N–18.
In the context of a ban on new types of ICBMs through 1985 with one exemption, MIRVed or non-MIRVed, for each side, we could agree to a ban on new types of SLBMs for the same period, with one exemption. In our case this would be the Trident II, and in your case this would be the Typhoon (RSM–52). Under this proposal, Trident I and the SS–N–18 would be considered existing types.
You have proposed a ban on new types of ICBMs for the protocol period, except that each side would be permitted to test and deploy one new type of ICBM with a single reentry vehicle. This proposal would prevent us from testing any new missile, while allowing you to go ahead with a new single RV ICBM for which we have no program and no need. This is inequitable and unacceptable to us.
You have also proposed a ban on new types through 1985, with the same exemption for a new single RV ICBM. This is even more one-sided:
—The U.S. would have no new ICBM for the duration of the 1985 agreement, since we have no program or requirement for a new single RV ICBM.
—The Soviet Union would, however, be able to deploy its entirely new type of single RV ICBM.
Finally, you have proposed a ban on the testing and deployment of new types of ICBMs through 1985, without exception. This proposal indicates that you can forego a new single RV ICBM. In that sense, it rep[Page 427]resents a constructive step to which we have given consideration in our own thinking. The logic of this proposal argues that you should be able to accept our proposal for a protocol ban on all new types, which would impose equal constraints on both sides.
As for SLBM new types, your proposal is the same for all variants: a ban on flight testing and deployment for either the protocol or the 1985 period, with an exception for Trident I and the Typhoon. This is not equitable. Trident I has already begun flight-testing and should be treated the same as SS–N–18. Soviet rights to a new, untested SLBM must be balanced by equal rights for the US. This means that Trident II and Typhoon must be treated comparably. Either they must both be banned or both be exempted.
There is also the question of how to define a new type of ICBM, which is being addressed by the delegations. The US has made a major move in the direction of the Soviet side, so we are closer to agreement on this issue. However, significant differences remain.
I want to emphasize the importance of a prohibition on an increase in the number of reentry vehicles on existing types of ICBMs and SLBMs. The US side notes the Soviet inclusion in its May 1978 proposal2 of the rule that in the course of modernization of an existing type, the number of RVs on that type should not be increased. We welcome this indication that you agree that fractionation limits for ballistic missiles are a valuable part of dealing meaningfully with the new types issue.
In this connection, we believe each side should specify how many RVs have been tested on existing types.
The US also regards as important the elements of our definition of new types about restricting changes in individual stages and in the relevant characteristics of what we call the post-boost vehicle for current missiles.
We also believe that an exempted new type of ICBM should not have more than 10 reentry vehicles, which is the maximum number tested to date on an ICBM on either side. Similarly, if we agree to exempt a new type of SLBM, there should be a limit on the number of reentry vehicles at 14, the maximum number tested by either side to date on an SLBM.
It is clearly important to limit the number of reentry vehicles on exempted missiles. This provision, along with the ban on increasing the number of reentry vehicles on existing ballistic missiles, would make a significant contribution to the effectiveness of a new types ban and to the stability of the strategic balance.
[Page 428]We have explained the rationale for the two alternatives for a ban on new types of ICBMs we have offered, and I continue to believe that either would lead to an equitable solution of this issue.
As I said at the beginning, the new types issue is one of the most important political-level issues remaining to be resolved in the agreement. If we are able to reach a satisfactory solution, I believe we will have made a great stride toward a final agreement.
In recognition of the importance of the issue for the progress of these negotiations, and in light of those constructive elements of the Soviet May 1978 proposals, and in an effort to bridge the gap between your proposals and ours, I am prepared to offer the following compromise.
I want to emphasize that in our view the new types issue has several related elements which apply to both ICBMs and SLBMs: a ban on new types, a definition of permitted modernization of existing types which prevents increases in the number of RVs on an existing type; and possible exemptions for new types. Our new proposal has been designed to resolve all these elements as a whole. It forms an integrated package and cannot be broken into individual parts.
We are prepared to prohibit testing and deployment of any new types of ICBMs through 1985, except that each side would be permitted to flight-test one new type of ICBM, MIRVed or non-MIRVed. However, deployment of new types of ICBMs would be prohibited through 1985.
—New types of ICBMs would be determined by the definition which we have proposed, including a ban on an increase in the maximum number of reentry vehicles on any existing type of missile. The exempted ICBM could have no more than 10 reentry vehicles.
—This proposal, when considered in relation to the 820 limit on MIRVed ICBMs, represents a meaningful arms control step. Yet it gives both sides flexibility in deciding how to structure its mix of MIRVed and single warhead ICBMs. We are also prepared to agree to a ban on new types of SLBMs through 1985, except that one new type of SLBM could be tested and deployed. The SLBM exemption would apply to Typhoon on your side and Trident II on our side. The Trident I and the SS–N–18 would be considered existing SLBMs.
There would be a prohibition on increases in the number of reentry vehicles for existing types of SLBMs. The maximum number of reentry vehicles on an exempted SLBM would be 14.
This proposal takes into account the essential elements of the approaches taken by both sides: you wanted to ban new ICBMs through 1985, and they could be banned. We have sought to obtain equality of constraints on both sides. It is good arms control and it gives each side flexibility to structure its own forces.
[Page 429]In making this proposal, I want also to make it clear that the US cannot accept a limit on the number of ALCMs carried by an aircraft limited under the 1320 ceiling, and this new proposal is contingent on your agreement that there be no such limits.
As I said, this new proposal is offered as an integrated package and cannot be broken into individual parts. We offer it in an effort to seek a fair and a prompt resolution of this issue.
I want to make two points in conclusion.
The United States has had no new ICBMs since the MM III, first deployed almost a decade ago. The Soviet Union has deployed several ICBMs in that period, most of them MIRVed and far larger than the MM III.
I must emphasize that by making this proposal the US has made a serious and substantial political commitment to conclude a new agreement. Unquote.
