It should be mentioned again in passing, how-— ever, that the proximity of the original CASTLE date to IVY facilitated--to a degree which normally cannot be expected-~an early determination of the nature of CASTLE military support requirements; and, as a consequence, IVY roll-up and redeployment were planned with these requirements in mind. Fortunately, this early determination remained basically sound despite the several changes in scientific concept which occurred. Even so, as plans progres- sed and as new test projects were incorporated into the scientific program, minor adjustments with respect to numbers and types of personnel, vessels, and aircraft had to be mde from time to time. Because these adjustments were requested only after thor- ough study and justification, the Task Force enjoyed exceptional cooperation from those commands providing the needed resources.
