The objectives of Operation Castle were threefold: (1) to fire some seven experimental
devices, six of which were to be in the megaton range and several of which were to be
proof tests of weapons; (2) to obtain that diagnostic information on these devices which
is necessary to evaluate properly their performance in case of either success or failure;
and (3) to obtain effects information for megaton-region devices.
