Conclusions @ ctcert @ A review of the sbove information results in our desi re to state the following conclusions : 1. Ih the concept of the operation as visualized without the use of Taongi it beeomes immediately obvicws that Operation Hardtack would be difficult, if not impossible, to secamplish in « period of time less than 12 weks. 2. With Teongi in use as a tect site, Schedule II is feasible, and far more assurance of being able to maintain the schedule is inherently asseciated Que to less average delay risk from both weather and shot intersection. 3. Sebedule I, without Teonei, is feasible but with less assurance es just stated. 4, Schedule IZ will guarentce completion ef the DOD high altitude program en schedule and in safe areas, while Schedule I will not. 5. Schedule IZ represents a saving af 7 weeks over Schedule I. 6. Belteving Schedule I to be typical timewlse of whet ean be accomplished in firing the shots, nov plemed for Enivetek, leads to the conclusion that the overall cperation ean be shortened by about one-half of the ccove saving er 3 to h weeks if firing of some Bniwetek shote is continued at Bikini after eomletion of Schedule II. 7. After review of the major requirements, and since no plens exist for the re-establishuent of the Foz/Cearge eamp or the maintenance of the semi- yermanent camp ashore at Tacngi during the operational phase, leads to ths eonelusion that the total Herdteck legistic supgert required with Taongi is no greater than Redwing with the exception of the diagnestics ship end Teongi weather ships participatics. 8. 9. It és eoeluded thet the ecst of any additional suppert plus the develop- mental ecst of Taongl is fairly estimated at $5,000,000 for Harditack. The use of a dlemestices ship not only constitutes the most inpertent fagter in making a Taonegl. firing site feasible but will provide a more economical means of aceamlishing the diagnesties experiments in the future. 10. he Laboratory will greatly benefit in personuel efficiency by the shorter stay of personnel cverseans an provided by Schedule IT. Zf the proposal is approved, we would make the follewing recomendations: 1. Ferform the conplete ecsancgrayghiec survey as scon as possible incorporating yepresentatives from egencies concerned in order to take the mst aivantage of the support remiired to plece and maintein people ashore for this task. Ageneies who might participate are Task Group 7.53 U.S. Kavy UD? No. 13 KEC, and Task Graw 7.1.
