. and operation were charged against AEC funds. Construction materials and installations for the proving ground were paid for by the .4EC. The estimated cost of the participation of the military services proved to be more than ample. AS the operation grew to a close, a recapitulation showed that this expense for the Fiscal Year 1948 was approximately $10,000,000. (Army $2,740,000; Navy $5,180,000; Air Forces $2,160,000). Accordingly, $8,000,000 was returned to the AEC by 1 May 1947 and an additional $2,000,000 was marked for later return. With the return of this sum, it was requested that $4,000,000 be made available to the Task Force during the Fiscal Year 1949. This latter sum was required to close out the operation and to place the proving ground in a standby condition. To sum up: The logistical support required of Joint Task Force Seven included the maintenance of approximately 9,800 men; construction and rehabilitation for housing and caring for the land based components of the force; the movement of personnel, supplies, equipment and material to support the force and for construction needs, both for housing and for the proving ground (55,000 M/T) and for maintenance of operations. Support was also provided for the “FITZWILLIAM’ program. Oahu, some 2,500 miles distant was the nearest base of supply. The larger portion of shipping came from the West Coast of the Mainland, some 4,500 miles from Eniwetok. On no occasion did the logistical effort of the Joint Task Force fail to provide the support necessary to the execution of Operation Sandstone, either as planned or scheduled. . . 88
