APPENDIX "A" BACKGROUND 1, Commission action on AEC 762/2, although approving declassification of the items listed therein, questioned the extension of the information to yields of 100 MT and the Commission expressed a desire to consider further the limit of yleld which should be used in the revision of the handbook "The Effects of Atomic Weanons”, It ts possible tnat in the future this’ capability may be increased to include weapons of 100 MT, Military requirements have been established for a weapon With a yleld in excess of the devices tested in CASTIE, These yields are applicable to Weapons capable of delivery by air. In addition there is a capability of producing weapons: of much larger yield for delivery by ship. Since little firm information is known regarding the capabilities in this area of potential enemles of the United States, it would appear reasonable to assume a similar capability to be possessed * by them. 3, The military requirements as roted above are for weapons with yields in excess of those indicated by the President in his statement of April 7, 1954. -5- Appendix "A" > mes &.\ me eS VS DISCUSSION
