The radius of the blast effects of BRAVO, however, was greater than
expected, and there was concern that the Eneman site, where the KOON device was already nearly completely assembled in place, could not effectively survive blasts at the closer location contemplated for shots UNION,
YANKEE, NECTAR, and ROMEO.

The second test, ROMEO, was not fired until 2 weeks after
its second scheduled date; KOON was fired 11 days later on 7 April.
A new schedule was promulgated 1 week after the KOON firing, which
reflected changing test priorities of the Atomic Energy Commission (AEC)
weapon designers as a result of the first three tests.

The revised schedule
as of 13 April for the remaining shots was UNION (16 April), NECTAR
(20 April), YANKEE (27 April).
This final schedule was modified to re-

The schedule changes affected DOD operations in several ways.
