Loper Chairman, Military Liaison Comittee to the Atomic Energy Commission A 408512 R COLLECTION -S¢drendory BOX No. —326-93700) Copies, Series aso BEST COPY AVAL & Dear General Loper: The Atomic Energy Commission is considering the occupancy and use of Atal for the condust of nuclear experiments. The use of aongl as a firing site in addition to Enivetok and Bikini has certain very desirable featyres. From the standpoint of fallout, Taongi is a safer place to detonate high yield devices than either Bikini or Eniwetok. The greater distances from Taongi to the inhabited areas of the Marshall Islands and its superior position with respect to direction from these areas are distinct advantages and give increased assurance against the repetition of fallout incidents such as that which occurred in March 1954. At the same time the greater ease of firing large shots from Taongi will have advantages in reducing the length of a test operation. It is estimated that Operation HARDTACK as presently planned vould probably be shortened by about three weeks if Taongi is used, and in addition Taongl may be the only place where it is feasible to test any of the very large yield weapons. It is planned that all firings at Taongi would be barge shots and all diagnostic data normally taken from land would be secured from a ship. The use of Taongi Atoll as an additional test site during Operation HARDTACK would require some afditional military support. requirements have been discussed with the JIF-7 staff. ‘The support If Taongi is to be used there must of necessity be coordination with the Departments of State and Interior. After concurrence by these agencies we would request the President to close Taongi Atoll for security reasons and notify the Security Council of the United Nations, as was done in the case of Eniwetok and Bikini.
