3. The briefing material contains very little Restricted
Data relating to design or fabrication of atomic weapons.
Specifically,
the only Restricted Data
is the approximate
expected yields shown in the table attached to Appendix "B".
A footnote on the second page of the text (Appendix "B") states
that Dr. Ogle will give information from this table only for
the shot which the observers will see plus any other shots
which at the time of briefing have been unclassified,
publicly announced.
To date only the LACROSSE and
shots have been announced.
Since the
1.
e.,,
CHEROKEE
talk will not present a
veryclear picture of Operation REDWING with only three snots
mentioned the staff recommends that the entire table of shots
be used with certain changes and that the above mentioned footnote be deleted.
The first change would delete the column
giving the date so the British would not be able to correlate
each shot with their long range detection measurements or debri
samples.
The second change would substitute "Low KT" (less tha
100 KT), "High KT" (100-999 KT), and "Megaton" (1 MTP or greater
for the Approximate Expected Yield.
Otherwise, by averaging th
approximate expected yields the British could get a close
estimate of thé
total yield from the REDWING series.
This woul
be undesirable since requirements of tre intelligence cooperattl
program will require giving the British later total fission
yield for the series.
In staff discussions with DOD personnel
the above changes were thought to be acceptable,
4, Since the proposed talk, with the above changes, no
longer contains Restricted Data a
joint determination under
Section l44b is not required and the Commission need only coneul
with the use of the proposed material for briefing the foreign
observers,
