Here is a 4 Mar. 59 memo for DDR&E from DASA on the subject of "High Altitude Weapons Effects Program for Operation Willow." This follows discussions of Argus TA at a recent meeting at Livermore on the subject from 4 to 18 Feb. and states, "the. conclusion reached by the AFSWP and the services is that the shell effect of trapped electrons is not one. of sufficient military. value. to warrent specific further investigation at this time. It is believed, however, that certain effects on communications and radars and other effects at the conjugate point and at surface 3 zero resulting from trapped electrons and/or fission debris do warrant further investigation." It goes on to state how this would fit into the AFSWP technical measurement programs and would require the inclusion of two additional shots from © Johnston Island with modifications to place emphasis on measurement at the conjugate points.
