so ag third categcry, proof tests, the DOD considers certain criteria demand that certain designs be fully proof tested which have not yet been and these are listed as: XW-54, Moccasin, XW-47, and XW-48. The fourth category emphasized by the DOD, is the areas of critical defense importance where the effects of nuclear weapons are not well underst*#od and can only be explored by further testing. Among the major categories are high altitude effects, surface and underwater effects on submarines, water ships, and aircraft; and x-ray effects on materials. The conclusions of the Committee on this draft report are: "A, The foregoing of all testing in the future will handicap, but not preclude the AEC's offering to the DOD warheads to meet existing or near-future DOD system requirements. Certain warheads offered by AEC will fall short of DOD desires in regard to assurance of performance, amount and predictability of yield, or other characteristics. B. The exploitation of certain fields of longer-ranged DOD interest, which could lead to significant changes in weapons systems and doctrine, could not be accomplished without further testing..... Cc. Foregoing further testing will preclude obtaining .ffects and phenomgnological information required by the DOD, of which the higher altitude effects are those of highest priority." Two appendices to this report are intended, the first detailing the estimated achievable characteristics and the methods of arriving at such designs, by the AEC for various devices. prepared The second appendix, to be prepared by the DOD, 8
