No unresolved fiscal problems arose during Operation CASTLE. Certain of the financial operations may be resolved into problem areas for the purpose of discussion, however. Perhaps the single most important matter confronting the Comptroller Division was the one associated with securing authorization for funds needed for new construction and rehabilitation on Eniwetok Island. In addi- tion to Typhoon HESTER damage, elsewhere described in this Chapter, this problem was affected by the decision to base the Air Force Task Group at Fniwetok. For tactical and administrative reasons, it was felt from the beginning that the Air Force Task Group should participate from Eniwetok. This had not been pos- sible during IVY, but was a vital planning goal of the early con- sideration given to CASTLE. By March, 1953, the mtter had been thoroughly studied and a survey of Eniwetok airbase facilities was initiated in order to determine what minimum improvements would be necessary. As a result of this survey improvements and repairs were recommended which would run to a total of one of two cost figures depending on whether improvements were to be made with a view toward long-range or short-range use.
