quired whenever possible. During the critical operating periods of M—5 days to M—1 day and K-3 days to K—-1 day, a detailed operating schedule was prepared and followed. When requirements exceeded the capability of the TG 132.1 boat pool, boats were requested from the TG 182.3 boat pool. H&N operated five LCU’s, one of which was at Bikini, to support the H&N camp development. These boats were used primarily for the movement of heavy equipment between Parry and the northern islands. Two of these boats were assigned to make Dewar runs,and the crews were trained for this special task by making several rehearsal movements of the Camco Dewar units under conditions of both daylight and darkness. The Navy operated five LCU’s, two of which made scheduled runs between Parry and the northern islands shuttling rolling stock. An average of one LCU was requested each day for direct support of project personnel of TG 132.1. The other two LCU’s were used for loading and unloading and for general movement of supplies. An average of 13 of the 19 LCM’s available to H&N were operationally manned. All LCM’s were not used because of the inability of H&N to recruit operators to replace those whose con- tracts expired during the operation. The Navy had 19 operational LCM’s, An average of seven were requested each day for direct support of TG 132.1 project personnel. Those boats not directly assigned to a project for its use were used for loading and unloading ships, ship-toshore movement of personnel, and recreation parties. H&N had three Seacraft water taxis, two of which were on scheduled runs to various islands of the atoll. An average of three H&N DUKW’s were required for work at locations inaccessible to , other boats. The other three H&N DUKW’s were used at Parry for carrying crews to moored boats. An average of seven Army DUKW’s were requested for exclusive use at the northern | islands. TG 132.3 provided adequate boat support in supplementing the needs of the TG 132.1 boat pool. The TG 132.3 boat officer trained his boat operators efficiently in the type of operations required at Eniwetok and furnished the numbers and types of boats required. 3.7.6 Off-atoll Activities In addition to the operational activities at Eniwetok, there were many other selected locations on surrounding islands where experimental tests in connection with Operation Ivy were conducted. The J-3 Section of TG 132.1 monitored the support requirements of these outlying units. Requirements werefirst submitted by project personnel at a conference on 14 May 1952. These requirements were tabulated and forwarded to JTF 132, TG 132.3, and TG 132.4 for planning and support. In planning requirements, on-site surveys by several project personnel were conducted to determine the feasibility of using the sites. After review by the J-3 Section as to the capability of furnishing support at the locations selected, approval for the use of the sites was obtained from JTF 132. The locations selected by TG 132.1, and approved by JTF 132, for experimental tests other than at Eniwetok were Kwajalein, Bikini, Majuro, Ponape, Kusaie, Ujelang, Wake, Guam, Midway, and Johnston. Approval for the use of Kwajalein, Ujelang, and the weather islands of Bikini, Majuro, Ponape, and Kusaie was obtained from CJTF 132. Approval for the use of Guam, Midway, and Johnston was obtained from CINCPAC, and CINCPACcleared the use of Wake with the CAA, Honolulu. Truk and other atolls originally requested by projects as desirable sites.were not approved by CJTF 132 because the use of these locations was considered inadvisable owing to security risks and the supportinvolved. The locations of projects and task units were as follows: Kwajalein: Projects 1.3, 2.5, 3.7, 5.3, 5.4a, 5.4b, 6.10, 6.11, 7.3, 7.6, 8.5, 9.4, and 10.2; 30
