Sanders, Subj: Taongi Atoll - Construction and Support Requirements B. J6 CONFIDENTIAL DI Sk. E-454dta'i'Feb '57 Title: Proposed Taongi Master Plan As directed during discussions of possible uses of Taongi Atoll held on 2 and 3 January 1957 (J3-H-28 and 29 dtd 15 and 16 Jan '57 respectively) we have examined the construction and support implications of using Taongi Atoll as a firing site. Two situations have been examined: 1. The minima condition described by Mr. Gibbins during the 3 January meeting which. considers a telemetering station and tower as the only scientific requirements necessary ashore for RARDTACK. 2. A maximum condition - which might represent the eventual use of the Atoll - consisting of a combination of the facilities found on Enyu Island and the Yurochi Complex of Bikini Atoll. Estimates of the construction and support requirements under these two situations in terms of manpower, time and money are con~ tained in Enclosure A. The concept of HARDTACK advanced by UCRL is certainly of a minimum nature; we feel, however, that if the Atoll is once used subsequent operations may result in an expansion of its facilities. We feel rather strongly that if there is to be any development of Taongi Atoll it should be accomplished in a fashion compatible with ultimate expansion to an installation comparable te a combination of the facilities now found on Enyu Island and in the Yurochi Complex of Bikini Atoll. With this is mind, Enclosure B is suggested as an Wh. ster plan.
