PREFACE
The purpose of this report is to present the damage to 1/4-ton
trucks (jeeps) as a function of dynamic pressure obtained froi Shots
3 and 6 of Operation CASILE.
A comparison cf the results is made
with damage sustained in Shot 10 of Operation UPSHOT-KNOTHOLE sud with
analyticel studies conducted at Ballistic Research Laboratories.
The.‘project plans in Operation CASTLE were flexible so that
participation“eould be accomplished in any of the shots in which the
conditions “2re determined to be suitable to meet the requirements of
the test.
The factors inflvencing participation were sufficient land
area nnd water-wave action.
Because of the revisions in shot
schedules and cancellation of one shot, active participation was
accomplished in Shots 3 and 6 only,
Self-recording mechanical-type gages were used for measuring
dynamic pressure and static overpressure within the vehicle stations
vicinity. These gages were supplied by Project l.cb. A jolat effort
was made by both projects to utilize these gages in the nost
efficient manner in order that both projects could echieve the desired
objectives. For descrintion of the gages and details of instrumentation, reference should be made to report prepared by Project 1.2b,
WT-905.
The following individuals were. active participants in Project 1.@
during Operation CASTLE in the capacities noted:
E. J: Bryant,
project officer;
Captain J. L. McGoy, deputy project officer;
d. D. Puppstadt, damage evaluationand consultant;
Corvoral A. W.
Garrard, field work and gage installation;
Pfc. J. R. Michalak,
a
CK. L. McCoy, field work and
field work and gage installation; and.
gage installation.

Grateful acknowledgement is madetoC.;W. Lampson and E. E. Minor
of Ballistic Research Laboratories for providing technical agsistance
throughout the various stages of the project, To Lt Col B Jones and
Ma‘or J. Brandenburg, of Armed Forces Specimi Weapons Project, special
appreciation is expressed for suggesting and indicating the requirements for this project.
Perticular and grateful acknowledgement is méde to N. H. Ethridge
of Ballistic Research Laboratories fe. the calcutations performed
concerning the effect of pcsitive d'ration on damage. : |
Grateful appreciation is expressed for the technical eaaistance
rendered by LCDR W. L. Carlson, USN, Director of Program iy. at the
test site.
Appreciation is expressed to personnel of Tasx Unit 8°‘and Task.
Unit 9 for the technical and documentary photography they provided.
Also, grateful appreciation is expressed to the many support
;
divisions, withcut which very little of project work could have béen.
accomplisted.
