A requirement of the Headquarters of JTF SEVEN was the preparation and submission, by each Task Group, of a checklist of tasks to be performed for each event covering the period of Shot Day minus five through Shot Day plus three. These check lists covered major events and indicated when facilities could be secured, equipment moved, and which utilities were to be left operating during shot time. The lists were supplemented by Task Group 7.1 vehicle and van movement plans which identified the vehicle or van, its location, date and time to be picked up, and its destination.

On the arrival of the USNS Ainsworth at Bikini Atoll, just prior to B-Day, arrangements were made for messing, berthing and for other facilities on board, and for the help and person- nel the Contractor would provide to assist the vessel in supporting Task Force personnel.
