operations by establishing a single authority over all components, military and civilian, of the task force. 8. Military support forces provided were adequate and essentially in the correct amount. po DELETED ee eer: 10. . . oo The emergency capability of high yield thermonuclear weapons in the mega- ton range was demonstrated. ll. The weather, primarily upper wind patterns, determines to a great extent the detonation schedule of weapons and devices in the megaton range when they are fired from the ground or on barges over shallow water. 12, Realistic fallout predictions for high yield weapons require reliable wind forecasts for the first 24 hours following a detonation. Data obtained during CASTLE mst be studied in order to develop dependable criteria for predic-~ ting fallout resulting from high yleld detonations. A network of manned stations equipped with appropriate instruments and radio facilities will provide a valuable "safeguard for populated areas within five-hundred miles of the shot site, 13. Fear of causing a tsunami of destructive proportion as a result of very high yield detonations will be present during future tests until this question is resolved. RECOMMENDATIONS 14. That the Joint Chiefs of Staff and the Chairman, Atomic Energy Commission note the above conclusions. 15. That, incident to future overseas tests, joint Atomic Energy Commission - Department of Defense public statements be released prior to the start of the test series, after each detonation and at the conclusion of the test series. 16. That an adequate danger area around the Pacific Proving Grounds be es~ tablished prior to future overseas test series and that information concerning the establishment be given wide dissemination. 17. That tests be conducted prior to Operation REDWING to determine the possibility of high yield detonations causing tsunamis. 18 That the Atomic Energy Commission and Department of Defense, utilizing 270) bane Cople \ -2-
