Conclusions and Recommeni3tion in 4.1.5 1. Where possible, the decentralized LCU setup with persac:s! living at their working place is very satisfactory. , 2. In order to cause the least disturbance to shipboard routine and passengers, it would be desirable in future operations to mess and quarter the experimenters aboard ship in separat= quarters or on ships of the MSTStype. , 3. Communications for experinienters were unsatisfactory when a number of channels hai to be operated in close quarters, as on shipboard. 4, It is absolutely essential that the number of persons between the experimenter and his transportation be kept to a minimum. This is largely because of the unpredictable nature of the transportation requirements. 5. The success of this operation was largely due to the centralization of operational con- trol on each atoll in one man familiar with the experimental pha-2s of the operation. 4.2 TASK UNIT 2, PRODUCTION w rhe function of TU-2 during Operation Castle was to produce the necessary, — = ” Td fulfill this obligation additiona! personnel,” were hired.

This program continued until Dec. 15, 1953, and included the making of necessary plant modifications. .

Foe | (Cambridge Corporation, with field offices in Boulder and Denver, Colo., was re- sponsible for all TU-3 activities. TU-3 was under the direction of the Task Unit Commander. To aid in administration, several groups who were under the direction of group leaders were organized according to their specific functions. 61
