ae shot would be cheap compared to a full Christmas Tree attempt and Bradbury understands that Foster supports the idea of a space shot directed toward the similar objectives. In a TWX to the labs and ALO on 12 Dec. Gen. Betts outlines the letters from Seaborg to the President on the NSC Committee shot list and recommendations for schedules etc. for an atmospheric test series as well as some of the President's feedback following the initial letter and asks that the labs continue planning for atmospheric testing according to this guidance. Among other things he notes that the President has not approved the atmospheric test list, nor has he approved the test period between April 1 and June 15, nor has he made a final decision on the actual resumption of testing. In a TWX on 12 Dec. Betts asks Bradbury, Foster and Reeves to continue ! on T See ere considering the question of On 12 Dec. Betts sent a TWX to Bradbury in regard to a letter from the DDR&E to Seaborg on 1 Dec. That letter referred to the gray area of responsibility for certain types of test measurements between the DOD and the ACC. The problem area has to do with a particular effects test which the DOD felt was. being generated by LASL for the Army and hadn't been properly handled in that DASA should have responsibility for arranging and planning for effects tests as this was felt to be, The letter from DDR&E to Seaborg discusses in a little detail the historical and legal division between responsibilities for weapons tests diagnostics that affect performance and design of the weapon as being the AEC responsibility and output measurements and measurement of effects caused by weapons output as being the DOD responsibility. Betts is asking Bradbury for assistance in preparing the Chairman's response to the DDR&E letter and is taking the approach that this particular device, which is a warhead for the Nike Zeus, must have the military characteristics and in particular the neutron output spectrum verified and that therefore this is actually a test for diagnostic measurements that affect perform- ance and design of the weapon. Not only does Betts feel that there is mis- understanding between whether this is a development test or an effects test, or a test by some other name, but that also there was a question as to where the request for the test came and that Betts feels that it came from the DOD to the AEC and not as alledged from the Army directly to LASL. At the request of the President, Dr. Harold Brown, who I believe was DDR&E, sent the President a rather lengthy letter on 12 Dec. addressing the justification, for the need for and the specifics of the various tests which should be included in or should not be included in an atmospheric test resumption. Although Brown was a member of Seaborg's committee which had submitted a couple weeks earlier their own position, Brown comments here on the specifics of that. I believe he makes a strong justification for the need for development tests, as well as effects tests, and he makes some rather convincing
