Hd Gi Ch cD on tp GTSaiAa pCaoINIE c, It is considered mandatory that Operation HARDTACK, now scheduled for EPG in May, June and July of 1958, be conducted as scheduled. PILGRIM, if conducted in the Pacific, could be expected to start no earlier than November 1957 and continue for two to three months. If the informaticn therefrom is to be digested properly, and new devices fabricated, it is most doubtful HARDTACK could start May 1, 1958 and be completed in a reasonable period. It probably would prove necessary to delay its start and extend materially the completion date. HARDTACK will be made up of proof tests of weapons that will be stockpiled more than 9 to 18 months later, and of development tests of devices that will enter stock- pile more than 30-36 months later. The following comments indicate the impact of delaying HARDTACK. ps . I es * . ~ 7 - SE AID IF RA Na " Tae en emt Appendix "a".
