Dear Mr, Strauss:
In a letter dated 5 June 1958,* the General Manager of the
Atomic Energy Commission requested Military Liaison Committee
concurrence in the declassification of the cxact location and the
exact time of the Operation HARDTACK detonations which are to be
jointly announced,
Except as noted below, the Department of
Defense concurs in the declassification of the exact location
(to the nearest second) and the exact time (to the nearest 0.1
second) of Operation HARDTACK detonations which are to be the
subject
of joint AEC-DOD announcements.
However,
release of
this information concerning YUCCA, TEAK, ORANGE, WAHOO, UMBRELLA
and ARGUS, in which the Department of Defense has the primary
interest, may reveal additional information of significance which
should be protected,
It is recommended that no data for the
Department of Defense shots be released until the information has
been subjected to a technical review and evaluation by the
Department of Defense,
It is suggested that prior to the actual release of any
data on the exact time and place of the HARDTACK detonations,
Dr. James B. Fisk, Chairman of the U.S. group which has been
designated to discuss with the Sovicts methods for policing a
test moratorlum, be consulted,
