The project details are described in Chapter 3. There was no preshot evacuation of Parry and Enewetak, althobgh task force ships remained in the vicinity to provide an evacuation cabability if required. TG 7.2 was mustered on the beach at Parry to view the shot. The shot countdown was broadcast in the area and the task group Personnel were instructed to turn away from the burst and cover their eyed prior to zero time.

Following the shot, the fleet returned to the atoll and by 0745 was anchored in the lagoon. 315 A damage and radiation survey of
