sana Here is a !@->ril 1969 message from Ken Street of Livermore to Coronet oteware of DMA «: - refers to a 16 April 1959 plan from Livermore fora proposed undergrour .3¢ program through about 1 September 1960. < Z. After presenting a list of mans ots addressed to either detection research or weapons development with ready - «5 any time from June of 1959 into 1961, and noting that the proposal "covers °!:': + the same objectives as yours in the weapons development shots but differ . stantially in the exploratory shots," Street states ''The Laboratory believes/: tous 90-day readiness produces extensive wasted effort and and will." - end lead to hurried and inefficient testing. funds, Furthermore, we believe t*‘' ---ause of the international situation, it is very unlikely that we will be permitted to test in the atmosphere in the near future; and therefore, that the most probable form of test resumption will be underground, later, in space. and somewhat We do not feel that being excluded from the atmosphere will severely hamper weapons development although there will be some delays in getting started on tests in the larger sizes. Therefore, we strongly recommend that plans be made for orderly and essentially continuous underground tests as proposed in our plan and that tests in space be considered starting 12 to 18 months from now.'"' He then gives specific comments on the tests proposed by DMA for underground and also, in the atmospheric regime, states ''Assuming an unlikely EPG or ocean program, we do not believe that we can be ready in less than 6 months to do any more than very urgent "quick and dirty" tests." The final paragraph refers to specific DMA questions and states: ‘Sufficient diagnostics could probably be obtained in open ocean testing for all of the shots listed using the same techniques used at Bikini during H-rdtack. important diagnostic measurement could not be accomplished. However, some Shots inthe upper atmosphere can be performed but only very rough diagnostic data could be obtained next spring. In about 18 months we expect that acceptable measurement techniques would be developed."
