In regard to the timing of the CASTLE Operation, Los Alamos proposes in Enclosure "Bi that March 1, 195), he set as the target date for the first test. This is basod on the rate of supply of lithium6, the time required for fabrication, shioment, and assoubly of weanon components, and the schedules for construc- tion of test sites and installation of equiorent at Bikini and iinriwetok. Although there is no one vhase of the prenarations wich prohibits the start of CASTLE a Little earlier, every phase is so tight that March 1 seems the best tarcet date to set for the initial detonation, Tentatively establishing a less realistic date would lead to confusion in planning and conducting the operation and would probably not result in am earlier successful completion of the operation, 11.
