372. Memorandum From Prime Minister Macmillan to President Eisenhower0

I was so grateful for what you told me today about our decision against a fixed-site rocket and in favor of mobility. I am sure this was the right decision, but I was very heartened to hear you with all your experience confirm my view.

I was also grateful to you for expressing your willingness to help us when the time comes by enabling us to purchase supplies of Skybolt without warheads or to acquire in addition or substitution a mobile MRBM system in the light of such decisions as may be reached in the discussions under way in NATO. As you know either I or the Minister of Defense must make an announcement about Blue Streak before April 131 and I was glad to have your confirmation that the following form of words would cause you no difficulties:

“The effectiveness of the V–Bomber force will remain unimpaired for several years to come. The need for a replacement for Blue Streak is not, therefore, immediately urgent, nor is it possible at the moment to say with certainty which of several possible alternatives or combinations of alternatives would be technically the most suitable. The Prime Minister, after discussion with the President, understands that the U.S. Government will in any case be favorably disposed to the purchase by the U.K. at the appropriate time of supplies of a suitable air-borne vehicle for the delivery of a British warhead. We shall also be considering the acquisition of a mobile MRBM system. Discussions are at present under way in NATO on this question and our decision will be taken in the light of the outcome of these discussions.”
