APPENDIX "c"'
DRAFT LETTER TO THE CHAIRMAN, MLC
1. This is in answer to your letter of June 20, 1956,
concerning the proposed briefing of United Kingdom and Canadian
official observers by Dr, Ogle, Deputy Commander for Scientific
Matters, JTF~7.
2.
The Commission requests certain changes be made
table of shots attached
to the proposed talk.
in the
As presently
written Dr, Ogle will be able to discuss only three shots
(LACROSSE, CHEROKEE, plus the shot observed) from the table.
Since these will give a very incomplete picture of Operation
REDWING we suggest Dr. Ole we authorized to present the entire
table but with the dates of the shots deleted and the "Approximate Expected Yield" replaced by the following:
"Low KT"
(less than 100 KT)
"High KT! (100-999 KT)
"Megaton” (1 MT or greater)
If all shots are listed, giving the dates of the shots may
permit accurate correlation of the shots with British debris
samples and
long range detection measurements,
Also,
if
approximate yields of all shots are furnished, by averaging
these a fairly accurate estimate of the total yield could be
obtained.
Since it may later be desirable to furnish the British
the total fission yield of the REDWING series in connection with
intelligence cooperation we believe it undesirable to give even
approximate yields of all shots.
3. With the changes noted above the Commission concurs in
the use of the proposed
talk for briefing the foreign observers
