_M&R Record Center BA "635 Johnston Island" Folder The first evidence that there Is a decision to move the Teak and Orange Shots of Hardtack to Johnston Island from the Eniwetok area is in a TWX dated 9 April 1958 from Ogle at Eniwetok to Al Graves. ‘Ogle mentions that moving to Johnston will cost some electromagnetic data on the DOD side, but essentially nothing else. Herman Hemtand and Ogle feel that J-I0 and NRL can partichpate at Johnston in the same manner as at Eniwetok. New construction wilf be nec- essary but Starboard has: indicated that they can dig this up out of AEC funds. Note that the ALOO report on Hardtack notes that the Teak and Orange events were relocated to JI on 9Apr.5h. - | Cc V -° In April there was a query from DMA to Bradbury He=reply on the possibility of using clean warheads for the Teak‘and Orange shots versus the warheads that . had been planned. “ Comettrrtenet This was apparently driven by a request from who {Is concerned about fall-out Libby and Bradbury's reply is that since the design of the clean warheads is in such.a primitive state and they are not planned to be ready until like [960 any use of these warheads In a mated configuration with the Redstone missile would probably mean that they would not stand up under flight conditions and certainly would require some interfacing and testing before the actual weapons test. In short Bradbury is pessimistic that the state of } development of the clean weapon is such that it would be profitable to employ it on Tea k and Orange. As plans and activities increase at Johnston Island for the Teak and Orange shots to be done there at the end of August, about the end of June, It was realized —thtecmea. é : . that there might well be a 4+erme-radiation problem to the birds on Sand Island CJ.A. -f vindar enraw wae heina set up to cope with this. . %. cm
