fo: Distribution “2= December 27, 1956 J=15G=178 1) 4-5 surface shots larger than 2 MT 2) 6=7 surface shots between 0.2 and 2 MT 3) w=8 “small” shots, surface and tower 4) 1 balloon-borne2 KT shot at 90,000 ft. 5) 110 KT shot at 150-ft. depth in Eniwetok lagoon There is in addition some possibility of two more water shots and two missile-delivered high-altitude shots. In working out the concepts, I suggest using items 1-5‘ above plus one missile-delivered shot of a megaton range warhead burst at high altitude. This last may be regarded as a reduced version of Sandia's "STARDUST" proposal. In determining the locations of the zero points, it may be worthwhile to recognize that the sponsorship of shots in items 1, 2, and 3 is approximately evenly divided between LASL and UCRL. Also, the Navy has indicated to AFSWP that they favor the southwest section of Eniwetok lagoon for item 5. This preference is based, however, on the idea that a deepwater shot 10 miles outside the southwest reef will be included in HARDTACK and that some landbased instrumentation could then be convenient to both locations. Finally, you may feel that shots larger than 2 M? should be fired at Eniwetok as well as elsewhere; at about this level the air Task Group will begin to fret ahout the safety of low perrormance aircraft on the ground at Eniwetok Island. The scope of the instrumentation to be connected with the above program is somewhat more difficult to estimate. It is probably correct to assume for the most part that the instrumentation will resemble REDWING. There are, however, a few known modifications. There does not appear to be any shot ‘dn items 1 and 2 requiring extensive instrumentation along the lines of CASTLE Bravo or REDWING Zuni. AFSWP does not plan an area-wide fallout program nor, at the moment, does AEC. Apart from launching, radio track- ing, and telemetering equipment, AFSWP will require no ground-based instrumentation on the high altitude shots. Furthermore, they do not intend to fire auxiliary instrument-bearing missiles, but they do intend to fly some instruments at 40,000 feet in two B-36 aircraft. The Raydist system will be replaced by a new manned system which will not require offatoll stations. There will, however, be some off-atoll microbarographic stations. There is not mich to go on but perhaps you will be able by making some judicious assumptions to arrive at some estimates of where to locate the shots, how much new construction will be needed, where and how large the temporary and permanent camps should be, what will be needed in the way of water and air support, what communications are necessary, in what order the shots may or will have to be fired, etc. s2eRPP {
