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

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

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

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
