CONCLUSIONS AND RECOMMENDATIONS
The data obtained in Operation CASTLE were sufficient to evaluate
“iy dynam! vressure as a damage parameter and also to determine the mag“nitude of dynamic pressure required for specific type darage to 1/4
ton trucks for a set of conditions as that in CASTLE. The limited
data ‘of CASTLE when compared to Shot 10 (UPSHOT-KNOTHOLE) suggests
that :.the ideal dynamic pressures were effective in causing damage on
Shot 10. However, because of the uncertainty as to what effect the
long pesitive duration has on damage the values of dynamic pressure
causing damage on Shot 10 remain questionable. In the CASTLE resulta,
it was not possible to separate the effect of dynamic pressure on
damage from the effect of the long positive duration on damage.
Reasonable estimates of ground ranges for spect/SYPe damage
to 1/4-ton trucks can be made when the scaling is as
» where W is
yield of weapon.
.In view of the knowledge accumulated on damage to jeeps under
varied blast conditions, the jeeps can be regarded as respons: gages
to forces resulting from nuclear blasts. It is recommended that in
future nuclear tests jeeps.‘be exposed along with instrumentation for
basic blast measurements.to. investigate any variations of the blast
and its effects on damage. ‘to drag sensitive targets under various
conditions of nuclear detora
