device components or designed and fabricated by project personnel
Nuclear components were obtained from standard production through
the AEC.
On of the major phases of the project activities was coordination with DOD agencies and other support groups to devise a
workable emplacement and firing system.
This included taking
part in various conferences and test from the initial planning
stages through preliminary sea trials of the suspension system
and dry run activities prior to detonation.
Checkout and assem-
bly was completed prior to placing the devices in firing position.
The device case and underwater signal cables were water-pressure
tested before acceptance from the manufacturer.
The electrical
equipment for firing was tested on numerous dry runs for satisfactory operation.
The two devices were detonated satisfactorily
without any major difficulties or delays.
Some troubdle was
encountered on the WAHOO event from fairly rough seas which made
the zero instrument platform (LCM hull) very unstable.
This was
not only uncomfortable for personnel, but created very unfavorabl:
working conditions and deteriation of equipment.
These conditions
were corrected on the UMBRELLA event through the use of a larger
platform (LCU hull) in an anchored position.
A few trouble spots developed in the fabrication of equipment, such as the zero instrument platform, for use by several
agencies.
These conditions were brought about by poor coordina-
tion between the users and fabrication agencies.
For any future test of a similar nature, the following
recommendations are offered concerning the activities of Project
