Copaa-313 Penne eat $=. Ee , ' February 19, 1957 * The conclusions and special requirements pointed out in the study may be summarized briefly as follows: 1. The use of Taongi and Bikini would shorten UCRL operations overseas by about 7 weeks, over that time vequired if only Bikini were available. The effects on shortening the operation as a whole is not fully known but it would likely amount to three weeks to a@ month. : 2. Taongi would be used only as a barge site. All diagnostics end firing would be accomplished from a “ghip. Use of the ship will permit flexibility in operation and will further reduce the time of stay of ‘technical personnel overseas by abeut one month, since *- dustallation and dry running of equipment can be accomplished while the ship is still at San Francisco. The © ship will need to be diverted soon in order to provide adequate time to fit it out. It is estimated that fit- ting out of the ship will cost about $1,200,000. 3. The cost of site development on the basis proposed ia estimated at $3,000,000. In view of all of the stated considerations it is our recommendation that the Taongi site be developed for use during HARDTACK. As a corollary requirement, a weather station should be established at Taongi now, even if ship-borne initially, to collect meteorological data through the present year. Sincerely yours, G. W.
