fe OPTIONAL FORM NO. to ; i “Doe ID: 6S RE @ UNITED STATES VERNMENT \ Memorandum DATE: June ,.19787 » ie wl 44USC2107(5)(g)(2)(D) SUBJECT: HCSA Request for NSA Material on Kennedy Assassination b(iii) 1. Based on our discussion with Judy Mijller,,- my understanding was that Mr. Blakey's most recent request, for-data from NSA involved a review of post-assassination[L__ ]product on a world-wide basis to determine if reports relevant to the assassination exist. Though Ms. Miller did a not specify a.time period, a three month period subsequent to the event would involve - as an example - six to nine thousand reports and would require 120 to 150 hours of analyst time just to conduct a manual search of the microfilm files where these records reside. ‘2. I subsequently spoke with Mr. Roger Denk, DIA, who had actually participated in the briefing of Mr. Blakey, -using our SECRET-level’ statement as a basis. Mr. Denk advises that DIA has destroyed all its files which might relate to the assassination and that, therefore, he had had nothing ‘to offer Blakey except the NSA-prepared sanitized statement. Mr. Denk also provided a different, much more ambitious new requirement from Blakey than that reported by Judy Miller. 3. According to Denk, what Blakey really wants from NSA is for us to conduct a thorough review of all Cuban communications during the six year period from January 1959.to December 1964, in order to see "what the Cubans were talking about/thinking about" of possible relevance to the assassina- tion - a real. fishing expedition in my view. Blakey is also reported to desire a "characterization of the traffic" - and not the traffic itself. 4. This latest version of Blakey's interests, which has probably been stated to us fairly accurately by Denk, represents a very significant work load indeed. Based on some very educated estimates made by the people in T12 who maintain the historical microfilm’ files, -there were approximately 200,000 Cuban reports or translations issued’ during the six year period of interest, and roughly 2,000 man-hours of effort would be required to search these records for items of interest. 5. As we have discussed previously, I believe that NSA - in a number of separate, thorough analytic efforts - has performed ‘reasonable and detailed reviews of all available signals intelligence. None of these reviews has resulted in’the derivation of any data of direct significance to the assassination. A summary of these separate. NSA efforts is attached.
