DOD EXPERIMENTAL PARTICIPATION
The CASTLE experimental program primarily focused on development] of
usable thermonuclear weapons, with secondary interest on their effects.
The DOD participated both in weapon development and effects reer
but concentrated on the latter.
Within JTF 7, execution of the experi-
mental program was the function of the scientific task group (TG l).
WEAPON DEVELOPMENT
TG 1 was subdivided into 12 task units that conducted the progran.
Both of the AEC weapon design laboratories had task units (TU 1 and
12)
that conducted their experiments; an additional task unit (TU 13) cahducted DOD weapon effects experiments.
Support for these experimentB
was
provided by nine additional task units.
The 12 task units are, described in Chapter 1.
The names of the
Rask
units and the number of persons who participated in each are shown i
