C-54 To be used for logistic support in providing interatoll passenger and freight lift, It is the under-— standing in this h: adquarters that General Canterbury (AFSWC) has asked for 2 C-54's to replace the C-47's now based at Eniwetok, Colonel Massey stated that this headquarters will support this request and that the requirement will be included in the proposed JCS directive to the Air Force concerning logistic support. C-123 To be used for augmented logistic support in interatoll airlift during the operational period, Characteristics of the C-123 seem most suitable in providing JTF-7 airlift of cargo and people between atolls. On this basis, they are far preferable to the C-47's. To be used in conjunction with helicopters in providing inter-island logistic support. 190 H-21 To be used for inter-island support at Eniwetok, The H-21's will be used in lieu of the H-19's assigned during Operation REDWING, Since the Air Force is . phasing out the H-19, the H-21, although less suitable in some respects, is considered the only feasible substitute, A temporary requirement for some H-21's at Bikini during build-up period will be met out of the total number, It is intended to utilize these aircraft to alleviate the otherwise heavy burden placed on the L-20's of providing intra-atoll transportation for VIP's, They will also be used as proficiency planes for rated flag and general officers. 16 B-57 To be used as sampling aircraft, Six of these samplers should be B-57D's, In the discussion which followed concerning this type of aircraft, LTCOL Edwards pointed out that they were very scarce and just were not available at the present time. Colonel Massey replied that if there mst be a substitute for the B-57D's, then it should be the B-57B's, as the laboratory people do not feel the F-84 has sufficient range and ceiling to ful- fill the sampling requirements for HARDTACK, He also noted that a significant point to te considered is that the laboratories have fabricated a large number of tanks designed for the P-57's and that if the JCS decides that something other than the B-57 must be provided, it is going to involve a requirement for additional funds in order to fabricate a different type of tank, AFWL/ HQ Donel Sip 3
