6 nds 10 - Typical Nuclear Test Event ee: The following pages illustrate the preparation and execution of a typical nuclear test event from the standpoint of Task Group 7.) Operations. TheROSE Event was selected for portrayal, The test will be covered from the preparation of the operation order to the debriefing and critique after the last aircraft had landed, The test aircraft participation was decided upon prior to the operational phase of HARDTACK and was outlined in Annex B to Task Group 7.) Operation Plan 1-58, The participating aircraft, the projects which they supported and the general purposes for their participation were outlined in the referenced document. Occasionally, changes to the test array as outlined in Operation Plan 1-58 were made. The only change for ROSE was the addition of a Task Group 7.3 P2V, whose mission was flying a rad-safe barrier partrol post H-~Hour to the array. By D minus three (3) days, a supplementary operation order was pub- lished for each test event. The order for ROSE, Task Group 7.) Operation Order 18-58, was first published six (6) days prior to the actual detonation. Some difficulty was experienced in obtaining positioning data and a safety certificate for these planned positions prior to original publication date of the supplementary operation order. The positioning data and safety certifications were the responsibility of Task Group 7.1. The difficulty in obtaining this data from Task Group 7.1 was unavoidable in most instances due to "D" days for shots on which the projects wanted to participate being scheduled close together, Frequently there was insuffi- cient time to reduce data gathered on one (1) shot in time to produce On ROSE, this 3 145 APAL/HO | i wa qm f positioning criteria in a timely fashion for the next shot.
