change such an announcement procedure at a later time. Additionally, he thought considerable weight should be given to the views of the intelligence community with respect to such a plan. Mr. Floberg commented that while he thought there were advantages in a new policy of announcing all shots, if the intelligence services had sound reasons for requesting that this not be done, he would agree to the proposed limitation. Mr. Graham said that his chief concern was that the AEC might be accused of wanting to withhold announcement of small shots so as to avoid talking about detection and that the AEC would then be in the same status as it was following the controversy over the range of detection of the Rainier shot. In view of the representations made by the Intelligence community and primarily CIA, Mr. Graham said he would accept the proposed procedure if it included a provision for informing the Joint Committee about the 200 kiloton cut-off limit and the reasons therefor. General Fields indicated his understanding that the procedure called for informing the Joint Committee of these reasons as had been done in previous test series, but that he would verify this upon return to Washington. Mr. Strauss observed that in previous tests the Joint Committee had recognized the need not to announce some shots. Nevertheless, he asked General Fields to instruct Mr. LaPlante to visit Chairman Durham on April 28, 1958 and provide him with the background and the reasons for the procedure. After discussion, the Commission: a. Approved the Joint AEC-DOD Operation HARDTACK Public b. Noted that the Joint Office of Test Information Information Plan (Appendix "A" of AEC 952/46): authorized under the Plan will issue announcements of all HARDTACK test detonations having predicted yield of 200 kilotons or higher.~ (Specifications for announcements are given in Paragraph 6, Page 5, of Appendix "A" of AEC 952/46 and rationale of the yield criterion is discussed in Annex "A" of Appendix "A" of AEC 952/46); c.
