Ce UCRL Participation: The advent of UCRL's participation in CASTLE placed a requirement on this division to make certain récommendations as to that Laboratory's integration into the Scientific Task Group. This integration had to be accomplished with considerati on that UCRL would be in a position Post CASTLE to conduct overseas operations independent of LASL. Prior to final decisions on this subject, several | joint orientation periods were held at doth UCRL and LASL. UCRL's responsibility for two of the CASTLE shots and certain diagnostic experiments connected with these and other shots remained firm throughout the period. f. Military Support Conferences: It became known in the early part of the period that the only means of handling shot barges was by the use ‘of LSD's. This Task Group expressed concern to the Joint Task Force over the effect that the barge movements would have on the Navy Boat Pool support normally provided by the LSD. It was recommended by this Task Group that serious consideration be given to the procurement of an additional LSD to support CASTILE. It became apparent that one LSD would have to suffice, therefore, attention was given to providing " additional facilities for the support of the boat pool during the absence of the LSD and obtaining the best possible schedules of barge movement so as to give minimum interference to boat support. The ° estimated boat, vehicle, helicopter and liaison aircraft requirements, were submitted to Joint Task Force besed on the then available experimental scope and experience factors obtained on previous overseas tests. (The requirements for support to be rendered by major elements, such as the USS CURTISS and the USS ESTES, were founs straight-forward. ) .
