Zab arguments about excluding several tests not biased towards either laboratory from the overall list as well as pointing out that the overall systems tests of the antisubmarine rocket, the Polaris and the Atlas, while highly deSirable if they can be done on essentially a non-interference basis, are cony not necessary completely for our confidence in these systems. l A 9 Dec. TWX from Graves of LASL to Col. O'Brien of DMA discusses in some detail the need for land-based diagnostics and the importance of being able to pinpoint exactly the device position relative to the instrumentation if such land-based diagnostics and precise accurate positioning is possible. meerneermnae mes AR t aa JA 13 Dec. TWX from Bradbury to Betts addresses A memo written by a Navy civilian named N. M. Brown of the Bureau of Yards and Docks on 11 Dec. reports on his meeting at AEC headquarters and his trisfing on the possibilitics of tho Pacific atmospheric operations by a Cmdr. Stephens. The memo for the files seems to be considering the fact that the AEC retains the services of Holmes & Narver for engineering and construction, etc. in the Pacific area as necessary and that therefore the Navy Bureau of Yards and Docks might not be looked on with any great seriousness if they offered their services to Gen. Betts. This memo was forwarded by a cover letter to Cmdr. Stephens of the DMA Test Office from Brown who stated that it was decided that the Bureau would not contact either Gen. Starbird or Gen. Betts at this time but that if the services of the Navy Bureau could be utilized at some future time that it would be appreciated if DMA would get in touch with them. A 15 Dec. TWX from Foster to Betts contains the planned LRL underground test program for Dec. 61 through Aug. 62 and includes shots. On 15 Dec. Bradbury sent a rather lengthy TWX to Gen. Betts on the subject of DOD and AEC responsibilities as brought up by the recent DDR&E TWX to Betts and the question of the so called effects test of the 50 X1Y2 device. Bradbury makes a strong argument for the misunderstanding DOD seems to have of just what it is that the AEC has been responsible for in weapons testing for years and points out that it was the responsibility of the AEC to de- velop weapons and make appropriate diagnostictexperimenta] measurements towards this objective and in addition, to provide by calculation or direct measurement for the using agency the definitive information regarding the fundamental output of those bombs. This, of course, specifically includes
