5. Dr. Bradbury of LASL,
Dr.
York of UCRL,
and Mr. Tyler
of SFO have recommended (see AEC 597/2) that CASTLE, now
scheduled for fall of 1953,
summary,
be rescheduled to spring 1954.
In
Dr. Bradury's reasons are:
a.
Information derived from Operation UPSHOT can
then be used to assist in designing and selecting
the best of the several competing models now being
considered.

Without this
information the laboratory cannot proceed
in an orderly, scientific way from the 80-ton Mike fixture, to
a 25-ton deliverable weapon,
between March 17 and May 21,
UPSHOT is scheduled to take place
1953;
evaluation of its data will
require several months following the test.
Thus, in order to
incorporate UPSHOT results in devices which are to be designed,
fabricated, and delivered in time for CASTLE in early 1954, the
theoretical work must be done very rapidly.
