Necessity of redesign and return of devices by LiSL and UCRL, 3. The addition of devices by those LASL and UCRL because of the pro~ Flasheblindness problem. posed moratorium and for other reasons. The total number of shots actually fired was » disted in Table 3.3. The general concept of operations given in the Operation Plan included the following: 1. A capability will be maintained to conduct independent operations and fire shots simultaneously at cach atoll, Bikini and Eniwetok, under the immedi te supervision of a Deputy Commander, TG 7.1 residing at .the atoll, 2. DE The devices to be tested by TU=-l (L.SL) will be detonated from sites in the vicinity of the northern islands of Eniwetok Atoll. ee eir larger vill be deton:ted -t Bikini \toll with zero sites for yield devices near the northern islends, and forthe smaller yields near the southern islands. Both lcboretories will normally fire their devices during the last hour of darkness before sunrise. 3. Two of the five DCD nuclear weapons, as warheads in the Redstone lidssiles, will be launched from Bikini Island. They will be fired at nicht at least two hours after sunset but prior to two hours before sun rise. The two underwater shots will be detonated in the vicinity of the southern islands of Enivwetok ‘toll, the first in the deep ocean, the second within the lagoon. The high altitude balloon shot will be launched from the aircraft carrier, USS BO-LR, positioned in the open sea , between the two atolls, These shots will be fired during daylizht hours. 4. Dry run tests of firing procedures and electrical si-nals for the effects and diagnostic systems, as well as rehearsals of special evac~ uation and re-entry measures wil] be announced in o»erational letters for each event. Essentially, after a scheduled ready date, each day will 5. The Bikini Atoll will be evacucted of all personnel (except those in-- volved in firing operations) for the Sycamore cud Foplar berce shots off of Namu (Charlie) Island. For the two shots, Teak and Orange, certain experimental stations, not on the Redstone ilissile trajectory (or its reciprocal), may be manned under specific authority of CTG 7.1. Othere wise the ..toll will be evacu-ted of all personnel not involved in launching and firing operations. On other shots, the up-island personnel will normally be evacucted to Enyu (Nan), “t 6. ‘hen evacuation to shipboard is required, normal posteshot RadSafe V3 and recovery operations will be initiated from the Nan base rather than 4%, = PGE PP
