Eniwetok was to be the supply and administrative base, Parry was to be the control center and contain several scientific installations. Another small island, Aniyaanii, was to have a photographic tower erected upon it. Troops were to move from island to island to meet operation and construction requirements. Engebi was conditioned to have a hous- ing capacity of 350, Aomon to have 300, Runit 250, and Parry 100, but these maximum capacities were only used for brief periods.
