- ee As stated before, Redwing planning provided such a capability; and when the CTG 7.1 operated from the firing bunker on Enyu, as he did on all Bikini shots.except MNMMDhe stationed one of his deputies aboard the USS Curtiss to ensure that operations could continue without interruption if communications failed or if re-entry proved impractical. *Communications by Motorola and AN/VRC-18 between ships and between the Curtiss and the firing bunker were generally excellent when the ships were at anchor, but deteriorated as the ships went to sea and became separated. Communications by the AN/TRC shipboard telephone equipment were generally unsatisfactory. After DEREth: Romurikku complex was untenable for permanent occupation, Therefore, operations ashore on that complex were supported from four H&N LCU’s, which had been converted to houseboats for this purpose and assigned to Programs 13; 15 and 18. A YCV, used as a helicopter barge, served both the houseboats and the shot barges off Yurochi. An LCU ; houseboat supported the shot barge. Movement to and from the houseboats _ to barge or complex was by helicopter or by LCM. Each houseboat had ant assigned DUKW. 3.11.2 4 Eniwetok Recovery and Re-entry Re-entry and data recovery problems at Eniwetok Atoll were simplified by having a permanent base of operations on Parry. Support craft and personnel necessary for each recovery operation were alerted and briefed prior to shot day. Following a radiological and damage survey conducted by CTG 7.1 and the Rad-Safe Officer, a recovery timetable was established. Factors such as station location, nature of mission, and the urgency of obtaining the data determined the departure times of the missions. Due to a lack of helicopters for the first event e recovery was primarily by marine operation. Four DUKW’s were moved to Runit by ; two LCU’s. The LCU’s served as a base of operations from which the DUKW's were dispatched to stations located on the island and on the reef north of Runit. Limited Rad-Safe supplies were also available aboard the LCU’s. This method of recovery was found to be successful within the limitations of the speed of the craft. The capability of shuttling samples and personnel from LCU to Parry by LCM and by helicopter was maintained. The helicopter shuttle was used to expedite sample return to meet returning to the U. S. Flyaways Although this capability was not used a proved very successful on subsequent shots. Lp Recovery on and later shots was primarily by helicopter. However, recovery of reef stations was always done by a DUKW - 103 - /00
