For the sea phase 114 buoys were laid; of these 77 were lost. Of the 37 recovered, 10 were damaged beyond repair and 17 required a major overhaul. The conditions under which the shot participation in the sea phase were made are best illustr.ted by Shot 4. Here placement and recovery of the buoys were done under the direction of CTG 7.3 and his staff with the advice and assistance of a project representative. Con- trol was maintained through the Combut Information Center (CIC) aboard the command ship, USS Curtiss, All necessary communication facilities were made available. Information on planting progress was relayed regularly to the CIC where it was immediately plotted. On the advice of the staff aerologist, late changes were effected in the array corresponding to shifts in wind patterns which would affect fallout. The first deferment was a 24-hr delay of the shot after all laying operations had ceased, The ships involved were directed to proceed to favorable positions tc commence placement of additional buoys. with the second defer. ment announced before additional buoys were laid and it being an indefi- | nite delay of the shot, recovery operetions were started immediately. Using a standard CIC system of coordinated aircraft and surface search, radar fixes were rapidly obtained on 11 of the 26 buoys ani recovery ships were directed to pick up positions. Buoys were located by homing on the radio signal transmitted from each. After recovery of seven buoys, the search was discontinued and the ships were ordered to Eniwetok to prepare for the next test scheduled there 48 hr later, On the busis of this experience along with recovery from Shots 1 and 2, it was concluded that the buoys and associated equipment rperformed satisfactorily. Although rough seas interfered to a great extent in the sea phase operations, fallout from most of the shots could have been collected fairly satisfactorily had the shot schedule been firn. The combination of deferments and rough seas resulted in the loss of
