as follows: 1-2KT on the suriace in the spring of 1962; 2-1/4 megaton detonations at 20 kilometers and 60 kilometers, one in 1962 and one in 1963; 1-2 megatons at 110 and 400 kilometers (400 kilometers in 1962 and 110 kilometers in 1963); and a fully instrumented ABM test in 1963. Thus, to do all these tests properly, would require two operations: one in the spring of 1962 and one in 1963. Event addresses the developmental objectives for devices which are felt to be most important by the DOD. for low First of all, is to increase the yield to weight figures weight warheads. As for aircraft-carried bombs, the aim seems to be more to clean up the devices than to increase the yield to weight ratio. For large missile warheads, the goal is maximum yield consistent with payload capability (like 10 megatons). ‘In low yield systems characteristic of tactical weapons, it is difficult to make an argumentfor atmospheric testing because it can all be done underground." As for the duration of the series, the DOD doesn't believe it is wise at this time to limit the operation to less than 3 months in length. Here is a 30 Nov. message from Batzel and Goeckerman to Betts on the details arent ra meee So et et of LRL involvement in possible atmospheric and high altitude testing as seen at this time. They note the diagnostics and techniques for making the measurements for both low yield and high yield shots as well as the incorporation of instrumentation in an open sea concept using ships and aircraft. As for the C-130 aircraft, they note that recent dry runs at White Sands have convinced them that several improvements need to be made, including X-unit signal telemetry, shock mounting to decrease vibration problems, etc. They also mention the proposed methods of diagnosing Space shots, including diagnostic packages blown on probes fired from Kauai and Johnston Island. eens ee tina” The DOD feels a minimum of six tests are needed
