In no sense would Bikini facilities equal those at Eniwetox, and the greater part of all preparatory, maintenance, storage, communication and other work would be done at Eniwetok. To further this » it was determined that several of the devices to be tested would be assembled and checked out on barges at Eniwetok which would then be towed to Bikini for detcnation. C. Because of the short time interval planned between IVY and CASTLE, it was determined that the Joint Task Force organization should be maintained in the interim period. Strength of “Eq TG 132.1 was shifted from IVY into CASTLE as Hq TG 7.1 with few changes in personnel, and little loss of numbers. During early 1953 a number of Task Group personnel were utilized at the Nevada Proving Grounds during the continental UPSHOT/KNOTHOLE test series. This move had the dual virtue of holding the organization together, and providing excellent training for future overseas operations. Even though the date of CASTLE was postponed it appeared better to retain as many military personnel from IVY as possible than to process and clear new personnel just before the operational phase. This has proven to be a justifiable practice, and has added to the relatively smooth planning and build-up of CASTIE, insofar as T 7.1 is concerned.
