Dear Dr, Plank:
DCS/Operations, AFSWC, recently asked Field Command, AFSWP, to
furnish us guidance on future test plans.
In particular, we were con-
cerned about the dual shot capability proposal for HARDTACK and the
possibility of simultaneous testing tn both the Pacific Proving Ground
and Nevada Test Site,
JTF SEVEN,
They, in turn, made inquiry to the Commander,
A part of the reply from JTF SEVEN signed by General Perry B,
Griffith is quoted for your information:
"The current concept being envisaged for Operation HARDTACK contemplates the probable firing of two shots on the same
day on some occasions, and perhaps in a few instances, at the
same time. However, while some additional aircraft will be
required, it is realized that a complete dual sampling capability probably cannot be supported, nor is it justified,
Therefore, in order to have an adequate number of sampling air-
craft available on dual shot days, attempts will be made to
have one of the scheduled shots a low yield detonation requiring relatively limited participation so far as sampling air-
craft is concerned,”
I still have not received the required information on the RB-57D
from Major O'Carroll, but should have it very soon and will let you
know,
-
Very truly yours,
WILLIAM 4. CUNNINGHAM
