Here is a copy of a TG 7.1 document mentioned elsewhere, a memo from Colonel
. Avery of J-3 for the record on 19 August 59, }33-W-96, subject "Testing of Nyclear
3
ena
‘tonations
on the Open-Sea.”
An open-sea shot is defined as “a surface shot so remote
have to be
com land areas that all D-l and D-day operations and diagnostics would
ynducted from ships, barges and airplanes.”
Among the assumptions arethat “the -
etonation sero site would be in the area determined during the ALO conference of
3 January 59 as being the most feasible, i. e., three hundred miles south of
aveaii; and that base facilities on Oahu and Hawaii will be made available for the
verseas
nurs part of the operation."
The January 59 meeting estimated it would
ake five months of preparation to conduct such ang open-sea test and the following
lanning ttems or actions have already taken place in preperation:
the Navy has
' eleased six LCl's for zero sites, three of which are being maintained by Task
roup 7-3
boat pool in San Diego.
H & N will do the modifications when required.
he Navy Task Group 7.3 has identified the other types of ships which will be
btaineble and appropriate for this type of an operation but no specific boats
ther than the LCU's are presently earmarked.
Also, J-6 and EG & G have designed
‘ransportainer type of CP that can be placed on an LSD for the firing system panel.
G 7.4 has addressed sampling and determiied “hat B-57 aircraft stationed either
m Oshu or Hawaii will have an ample safety margin to sample as far as 500 miles
way,
Certain effects of tests near the Islands have been investigated wit. the
yroblem of water waves being estimated by J-10 as six-foot waves in Hawaii for a
me megaton shot at 250 miles or a ten megaton shot at 800 miles distance.
Also
i1oted is that fall-out patterms will encroach on the main commercial sea and
airline routes between Hawaii and the Continental U.S.
Other details of the
sapabilities of the Navy ships and the requirement for standoff distances are
Listed.
