Survey of these atolls from a DDE type vessel is somewhat inefficient in that Rongelap is the only atoll, of the five visited, that can be entered and navigated safely, thus limiting the number of islands that can be covered ina given time. Boat handling operations outside the atolls were difficult due to heavy swells. “ith the forces available, it is believed that the use of a DDE is the most practicable solution for similar missions. For operations subsecuent to "CASTLE", it is recommended that a smaller class ship of shallow draft be used. This would permit entry into most lagoons shortening boat runs, in som? cases twenty miles. se o eo Se of of fooO 5 . &x. pee 5200 50? °Ni
