duplications of transmitting and receiving equipment. A frequency control officer should be ordered to the staff of CJTF 7 sufficiently .earlyeto coordinate all frequency requirements. In order to expedite procurement of special equipment, certain frequency bands, normally used by commercial telemetering equipment, should|be reserved for the Scientific Task Group. f. In order that the incoming Scientific Task Group Communi- cations Officer may become aware of problems encountered on an operation of this type, and to provide a TG 7.1 Communications Officer at each test site, this officer should report to TG 7.1 at least one month prior to the operational phase of an ensuing operation. g.- <A telecon room, similar to the one installed at Parry Island during Redwing, should be provided on Enyu Island and the TG 7.1 Command Ship. h. The need of a TG 7.1 Command and Firing Control Ship has been reconfirmed. Every effort should be made to improve the performance of the command ship communication facilities, principally by decreasing interference which was frequently encountered during Redwing. 2. f * Boat Support In general the boat support proved adequate. However, it is recom-~ mended that the feasibility of using fast water taxis at Bikini be investigated and, if practicable, that they be provided and employed in the next operation. 3. Mator Vehicles ' A system of vehicle maintenance (including necessary spare parts) which will permit adequate maintenance throughout the operation should be established by TG 7.5 prior to the operation. 4. Off-atoll The planning and funding of off-atoll activities should be completed as early as possible in order to permit the delivery of equipment at the PPG and the construction of camps and stations to be accomplished with the least interference with other projects and activities. 5. Air Operations a. Early agreement should be reached by the Task Force and Task Groups as to the numbers and types of helicopters and liaison type aircraft required. Both planning and utilization would be improved by an early general understanding of the types and estimated numbers of missions to be performed during the operation. b. L-20 landing strips should be constructed on Bikini Atoll at - 136 - a, | /33
