Discussions Bearing on Proposal
1.
Scope of Operation
The full scope of Operation Hardteack represents an increase in effort over
Operation Redwing of 75-1004. The figure of 25 to 30 shots total would offhand seem to indicate that Operation Hardtack will be 75-100% longer in the
operational phase, From the UCRL point of view, this is not necessarily
so as the schedules for firing at Bikini and Taongi will show.
It is our

e fired as a rather heavily diagnosed
surface or short tower shot. This shot, plus two or three of the lower
yield two-stage devices, and the five single stage devices will be comnitted
to the Tere-Uncle Island complex for testing. Such a firing program can
start with the beginning of the operational phase and be concluded as rapidly
aS possible. At the same time, preparations and firing of large devices
ean proceed on the northern side of the etoll. Also, concurrent with the
Bikini phase.of the testing, and if the proposal is approved, firing of the
large yield barge shots can proceed routinely at Teongi.

There is tentative agreement between the laboratories that either group
finishing their shot program in a given atoll would immediately make that
area availsble to the agency with shots remiining to be fired.
The UCRL
planning incorporates the use of Taongi in order to relieve both Bikini and
Eniwetok of yields which would be difficult to interweave with smaller shots
and which would necessitate being mich more selective in choosing a safe
shot day, especially at Eniwetok.
Following are two schedules for WRL shots
with and without the proposed Taongi firing capability. These schedules ere,
of course, not firm at this time, but incorporate the basic thinking and ere
therefore not just examples, but typical of the final Hardtack schedules.
