augmented by staff and program personnel from Eniwetok as test activities required. This arrangement provided efficient control of activities at both atolls with a minimum of overhead, and proved to be quite satisfactory for this type of operation involving experiments at both atolls. At Eniwetok the Commander, TU-3, supported by a small staff, supervised the activities of the directors of the eight technical programs. There were 47 projects grouped under the eight programs (see the organization chart, Fig. 4.1). During the course of the operation approximately 50 TUheadquarters personnel and 900 project personnel were present in the PPG. \" The peak strength was 710 on May 6, 1956. Ww Headquarters personnel were furnished by Field Command, AFSWP. Project agencies are indicated on the organization chart. The programs were the most extensive yet undertaken for an overseas test. Although the experimental objectives were numerous, the major overall objectives were to define or document (1) the weapon-delivery capabilities of late-model aircraft; (2) the radioactive fallout from high-yield devices, including the initial and final distribution of activity, the time history of accumulation locally and at sea, and the physical and chemical nature of the radioactive material; and (3) the basic effects of a high-yield air burst. In general, it appears that the program objectives were met, except for a considerable loss of data on the high-yield air burst BEERct-ro%ce) due to a bombing error. Individual program results are covered in Chapter 2, Section 2.1. *The TU-3 mission was accomplished without major operational problems. The large number of scientific stations involved in the weapon effects tests were widely scattered throughout the PPG and made the task unit dependent upon logistic-support agencies. Close liaison was maintained with TG 7.1’s J-1, J-3, J-4, and J-6 staff sections, and all essential requirements were met in an excellent manner. *Special problems were posed by the projects operating outside the PPG. Excellent cooperation on the part of staff sections, support agencies, and communications personnelled to satisfactory solutions. 4.4 4.4.1 TASK UNIT 4, SC PROGRAMS Mission of Task Unit 4 In addition to technical and adminstrative responsibilities for Sandia Programs, TU-4 was assigned administrative support and technical monitor Tesponsibilities for service projects being performed by Sandia Corporation for DOD, LASL and UCRL. These service projects included the following: - 143 ~
