cial transportation to Travis Air Force Base, Calif., or to the port of embarkation. 7. Notification to CINCPACthat each individual traveling to the Forward Area was considered a good security risk and of the type of clearance he possessed. Security statements were signed by personnel and filed in the J-2 Section office. 8. Notification by teletype to the AEC Resident Engineer at Eniwetok [information to Santa Fe Operations Office (SFOO)] as to the expected arrivals. The actual move to the Forward Area was as individuals rather than as units. Liaison of- ficers were stationed at Travis Air Force Base; Hickam Air Force Base, T. H.; and Kwajalein to aid personnel and to expedite travel. Most nongovernment employees proceeded to Hickam Air Force Base via commercial transportation. Most government employees and all military personnel traveled from Travis Air Force Base to Hickam Air Force Base via Military Air Transport Service (MATS). The majority of the personnel were airlifted by MATS from Hickam Air Force Base, and the remainder were transported by MSTS or Navy ships to the Forward Area. ‘ Although the majority of the personnel of TG 132.1 were located at Eniwetok Atoil, several of the units were based on Kwajalein and other Pacific atolls because of operational necessity. Most of these small elements were a part of the scientific-measurement programs of Task Unit (TU) 1. Other Task Units having a fairly large off-island responsibility were TU 5 and TU 9. TU 5, the assembly unit for the King device, operated at Kwajalein since this was the base of operations for the Air Task Group which dropped this device. TU 9, the Documentary Photography Unit, had approximately half of its personnel strength at Kwajalein in order to obtain documentary photography required of the air operations and, of course, the air-borne , photography at the time of detonation. Other units included in the approximately 100 personnel of TG 132.1 on Kwajalein were Projects 1.3, 2.5, 3.2, 3.7, 5.3, 5.4a, 5.4b, 6.4b, 6.10, 6.11, 7.3, 7.6, 8.5, 9.4, and 10.2 Although Eniwetok and Kwajalein were the main operational bases for Ivy experiments, a few of the projects had stations at Bikini, Majuro, Kusaie, Ponape, Maui, Ujelang, and Johnston Islands. Program 7 and some other projects monitored stations at several remote places throughout the world as a part of the long-range detection program and other studies. ‘ The Headquarters Commandant, TG 132.1, met all new arrivals of the Task Group at Eniwetok Atoll and effected processing, billeting, and arranged individual transportation to Parry Island or to the up-island sites as required. An accurate daily count of the population of TG 132.1 personnel was kept. The population curve by weekly increments is presented in Fig. 3.3. The peak population was reached on 24 October 1952 when 556 staff and scientific personnel and 1129 H&N personnel, making a total of 1685 in TG 132.1, were present at Eniwetok Atoll. 3.5.2 Equipment Owing to the nature of Operation Ivy (the testing of a thermonuclear device), the logistic problems involved in accumulating, shipping, and assembly of equipment were of large magnitude. The Department of Supply and Property, LASL, worked very closely with four major contractors in connection with the procurement of the necessary equipment for Operation Ivy. There were, of course, hundreds of other contractors who provided scientific and technical equipment. Much of the equipment required months of specialized engineering before the preliminary designs could be firmed up enough to order material. This required the use, in some case, of directives to obtain raw materials in time to fabricate, test, and ship them overseas without delaying the program. A critical problem of the Department of Supply and Property was that of arranging the shipping schedules so that there wo'-:d be space available to transport overseas, during the few 23
