Requirements - A preliminary review of major requirements which will be needed from the Military Services indicates that those set forth in CJTF 132's report to JCS dtd 4 August (rere series 2179), with adjustments, will be adequate even though the present Castle scope is much broader than that of August 1952. One such adjustment would be the need for a CVE of the Rendova class with the primary mission of furnishing a platform and support base for helicopters for both Bikinl and Eniwetok shots. In addition, sultable barges for cab platforms will be needed, in this connection the SFOO, AEC is now investigating the availability of these from commercial or government sources. Moreover, the many undeveloped islands on Bikini Atoll which will almost certainly be instrumented for effects and development experiments will increase the number of helicopters required, The requirements will be continually reviewed by Task Group 132.1 with a view of presenting detatled requests as early as possible. Subsequent revisions will be submitted as necessary. It is requested that the Commission approve the above concept at an early date in order that detailed planning can proceed, /3/ ALVIN C.
