Abstract : The objective of UPSHOT-KNOTHOLE Project 3.20 was to determine the effects of air burst nuclear weapons on selected items of signal communication equipment. Typical items of this equipment, such as would be found in a communications zone or field army area, were oriented in test groups at varying distances from GZ to obtain an anticipated damage spread from severe to negligible. Participation in Shot 9 consisted of 93 such test groups. Participation in Shot 10 was limited to 17 test groups because of shortage of funds, materiel, and labor. Photographic records of damage, and evaluations of the levels of damage, were made by project personnel. The anticipated spread from negligible to severe damage was obtained for the majority of the test groups. Recorded values, and predicted values (from TM23-200), for thermal flux, peak overpressures, and initial gamma radiation were in close agreement in both Shots 9 and 10. The damage from Shot 9 was about what was expected.
