dre,
The calculations we have made with respéct to such models
in general,
very similar
to
those which,
when applied
to the
models tested at Operation Castle, give results in agreement with
theobserved..resultstowithin about ten percent.
With ‘respect to the ‘matter of a possible test in Redwing of
such a device, we feel, as you know, that the list already avail-
able
of objects which will require to be
tested
merely to meet
demands specifically related to rather immediate military requirements is impressively long,
We are consequently reluctant
-to consider adding to this list if that can be avoided.
~~
| Although this proposal has received: prelimi-
ary consideration, we are not yet in a position to lay down a
design of such a device and it will require a rather favorable
rate of progress to be able to prepare this test in time for
Redwing.
At the moment, however, we are rather optimistic about
being able to do so,
Very truly yours,
