v- 7 A memo from a Major Rosen from the DMA Test Office to General Betts on 9 September 1961 addresses a DoD study entitled " Case for Nuclear Testing" and doesn't really seem to think much of the study as far as being at all comprehensive or really saying very much. Among other things the study notes the DoD's need for effects tests but doesn't make a very strong case for any justification for tests other than underground tests. Rosen goes on in his memo to list and discuss crucial problems in deciding whether testing should be done underground or in the atmosphere if there is a choice. Among other problems he discusses the time factor where atmospheric testing can probably do the same number of shots much more quickly than can underground testing, diagnostics where it is not known for certain if all the needed diagnostics can in fact be acquired by underground tests, costs where because of the time factor involved the lengthy underground series will cost a good deal more maybe a factor of several times more than atmospheric tests programs, and finally the yield limit on underground shots which would not exist for the same reasons for atmospheric or outer space shots. A 9 September TWX from Betts to the Labs discusses the inputs from the DoD after seeing the AEC's proposed programs and lists in particular the effects test that the DoD proposes and a priority in which they would like to perform them. Further, the DoD lists in their shot list 4 devices which they feel require proof or developmental tests which the AEC hadn't included in any of their lists and Betts asked for comments on these. list contains 44 tests to be done in a two-year test period. The entire DoD In addition to the Foster and Bradbury replies requested by Betts on the matter of atmospheric versus underground testing Hertford of ALO replies to Petts and concludos that given certain assumptions that tie makes one or LWO atmospheric tests could be quickly staged at the NTS and accomplished without too much consideration for public opinion because of the attitude of the people in that area among other things. AIC All In a 14 September TWX Schwartz of Sandia gives his feelings to General Betts of the atmospheric testing capabilities under various considerations. He ees cussaeystT face testing using balloons and feels that a response time for the NT fj bout 3 weeks whereas for EPG it would be about 90 days. On the subject of high altitude and outer space testing he notes the availability of Thor and Atlas boosters to lift various size payloads to the desired altitudes. He further notes the availability of small rockets and dicaps for diagnostics. As for response times it is estimated that using only ground based instrumentation or companion rockets Thors could perform high altitude testing from Johnston Island in about 6 to 8 months and using onboard instrumentation and dicaps probably would require about 12 to 18 months. Smaller payloads might be tested by launching them from the Polaris launched from the Norton Sound or a operational submarine on a shorter time scale. Area of outer space testing which would allow testing of yields one megaton or larger it is estimated that 18 to 24 months would be required to develop a site and prepare for such shots. Both Foster and Bradbury by TWX's in the 10 days following the 9th of September request from Betts for information on the DoD shot list replied to Betts with their comments on the DoD's shots not included in previous
