Daoust 2- General Fields began a discussion of the basic requirements for Operation CASTLE, He stated that planning should envisage two (2) shotsof the MIKE variety and two (2) smaller shots approximately GEORGE size wuld be fired, All things considered it seems that one MIKE type shot would have to be fired at Bikini and the other MIKE type plus the tw GEORGE type shots would have to be fired at Eniwetok if reasonable time schedules are to be met. He stated that it was important that a second proving ground not be established at Bikini, If a base camp and one or mre site camps were established at Bikini with two systems of communication, water distillation, power plants, recreation facilities, network of air and water transportation, etc., the cost and effort would be beyond present capabilities, ‘The only way tw (2) thermomiclear devices could be fired at Bikini would be by allowing a time gap of approximately 90 days between shots which would be extremely costly. The alternative is one thermomclear shot to be fired at Bikini and one at Briwots 3.
