[Dear Harold:] I have your memorandum dated March twenty-second1 to which there are four attachments dealing with the subjects of:
I. AQUATONE2
II. Tripartite Alert Procedure3
III. Nuclear Weapons for R.A.F. bombers
IV. Nuclear bomb release gear for
R.A.F. bombers
The first two items mentioned in the attachments are completely satisfactory to the United States Government, and I should like to add that we are pleased that you found your way clear to allow United Kingdom bases to be used for AQUATONE if it should at some time become necessary.
With respect to Item III, "Nuclear Weapons for R.A.F. bombers," I have a couple of additions to the phraseology submitted, merely to make certain that the meaning of the paper conformed to the requirements of United States law. The item as revised would read as follows:
"The United Kingdom Government welcome
the agreement to co-ordinate the strike plans
of the United States and United Kingdom bomber
forces, and to store United States nuclear weapons
on R.A.F. airfields under United States custody
for release subject to decision by the President
in an emergency.4 We understand that for the
present at least these weapons will be in the
kiloton range. The United Kingdom forces
could obviously play a much more effective
part in joint strikes if the United States weapons
made available to them in emergency were in the
megaton range, and it is suggested that this pos-
sibility might be examined at the appropriate time."
With respect to Item IV, "Nuclear bomb release gear for R.A.F. bombers," I agree of course that you shall probably have to make some statement in order to prevent speculation in the press that might prove not only inaccurate but damaging.5 However, as I explained to you verbally, the United States would prefer not to be a party to a public statement which might give rise to demands upon us by other governments where we should not be in a position to meet the requests. Consequently I suggest the possible adequacy of a unilateral statement by yourself or by the British Defense Minister to the effect that Canberras are now being equipped to carry atomic bombs.6 With warm regard
