Mission 2ei Same as in basic plan, 2.2 To obtain necessary information for the determination of an optimum procedure for the tactical and industrial recovery of con- taminated ships, 2.3 To reduce the total radiation field of each ship so that participetion in subsequent shots will not be a hazard to operating personnel, 3.
