pe
tests, it is possible the whole device will require reengineering since the case is a fundamental part of the weapon
rather than merely an envelope as for other bombs.
This,
in
turn, makes desirable allowing the longest possible period for
development before CASTLE.
10. Evaluation of the risks involved in selecting one of
the possible weapons now under consideration and attempting
to fabricate it in weapon form so as to be able to test it in
the fall of 1953 leads to the conclusion that this is not a
wise course.
Stopping, or materially decreasing, the effort
on two of the three models and designing the best case now
possible with our limited knowledge might make one model avail-~
able in time for test in fall 1953.
however, be almost unpredictable.
Its performance would,
Further, should any one of
the many arbitrary decisions which would have to be made to
meet this date prove erroneous, we would have no capability in
this model at all.
Centering all our effort on the one success-
full model, furthermore, would move back the date when we could
have the other models available for proof test to fall 1954 or
possibly later,
