aaa Messrs. York and Ogle, Dr. Dunham and General Starbird have now estimated that the size of the area over which this effect would occur is a circle with a radius of 350 miles. This means that if the shot is fired at the test site, the flash would cover the Test Site, Ronjelap and other islands and parts of the warning area. The Commander, Joint Task Force-7, General Alvin R. Luedecke, believes he can provide adequate warning and protection, Mr. Strauss said, but, although the results of this test would improve the defenses of the free world, the matter before the Commission is the responsibility for making a decision which may endanger the well being of people who are not represented here. General Starbird commented on the importance to our strategic defense of the data to be obtained from this test. It is expected to confirm a recently developed theory that, by establishing a magnetic field which holds electrons in bands around the earth, one can destroy enemy ICBM's or blot out radar. A side effect is interference with radio transmission through ionization of these bands which will then not bounce radio waves back to earth, Shooting the specially equipped satellite next week will place it in orbit in time to assure that the predicted effects of the TEAK shot on the satellite counters can be measured, The Killian Committee, when informed of the implications of the desired information insofar as our defense is concerned, had been disturbed at the possibility of the Soviets orbiting a satellite at this time which could also confirm this theory. It does not appear, however, that they will be doing so and the Committee therefore urges all possible effort to shoot the U.S. satellite and the TEAK shot as soon as possible, The flash from a night firing is expected to cover a 370 mile range in which 4000 natives are located. A day firing would cover a 220 mile range and 2000 natives. General Starbird said a night firing was preferable because more energy would be released and data measurements would be more accurate, General Starbird said there were three questions which had been considered: 1. Should a lower yield shot be fired‘ This does not appear desirable because a veduction from the planned yield of 3.8 MT to 500 RT would decrease the flash area by only 25 percent, Additionally, replacement of rocket gear would be hurried and possibly result in a test failure; » reedOY AE (SF eee ED fe on By -199-
