ge Program 5. 1-43 This progrem was designed to determine the effects of muclear weapons on aircraft structures, Nuclear weapon delivery by manned aircraft is often affected by the weapons! blast and thermal effects on the delivery aircraft and by nuclear radiation on the crew, Test data has indicated that blast inputs and skin temperature rise can be predicted within satisfactory limits, but that predictions of the aircraft's response to these inputs is much less reliable. In order to perfect delivery tactics, where safety margins are critical, manned B=52D, AiDe-l and FJ4 airereft were to fly several missions each, collecting data on the results of various inputse Program 6. This program was to study effects in 4 categories: 1. Electronic equipment located at various distances from the zero. point was to collect data to determine the feasibility of using the EM pulse from a nuclear burst for long and short range detection, and to study the fireball and nuclear cloud with radar for determing ground zero and yield. 2. Investigations were to be undertaken of the ionization effects of high altitude deton tions, particularly as they might effect communicae tions systems dependent on the ionosphere for propogation. 3. Investigations were to be made on the deleterious effects on fuses 4. On the underwater shots, experiments were to be made to determine and their components as a result of gamma rays and neutrons from nuclear explosions. the feasibility of using muclear explosions for clearing of mine fields. Program 8. This program included the evaluation of laboratory methods of scaling thermal effects with weapons yield. Probably the most important pert of the program participation was to investigate the little known thermal phenomena and the parameters which have a direct relationship on the damage producing thermal effects from the fireball of high altitude detonations and the prediction of those parameters for other heights and yields. Included was to be the photographic measurement of the fireball radius time history of high altitude detonations. Program 9. This general support program included a study of effect of dee Line Rees: coptenioor COM rr ine= . —~ LANL RO - eae , rue [@
