Files frm HCBrown -~-2- January 5, 1953 (1) Development, production, and delivery appear possible and (2) The concurrence of the DOD in accordance with existing agreement practicable; and be forthcoming. The FCDA would undoubtedly prefer an arrangement in which weapons development and planning data is routinely available to them in order that they could make their own determinations and predictions as to the effects on civil defense planning. Such an arrangement would be impractical in my opinion, and I believe it not at all unreasonable to expect FCDA to rely on AEC's judgment as to that information which would significantly affect or modify civil defense planning. We have a Civil Defense Liaison Branch not simply to transmit to FCDA infor- mation which they request, but rather to be familiar with civil defense needs and to anticipate their requirements for data, and be able to recognize information available within the AEC of use to FCDA. ec: Dr. Bugher SL “ DO’ ARCHIVES
