with the LASL group serving as the final clearing house for all three agen-
cles in transmitting the requirements of TG 7.1 to TG 7.5. During the planning phase the four UCRL representatives functioned from their own laboratory while the DOD representative established residence at Los Alamos.
During the instrumentation and shot periods these three groups combined in
the Forward Area and representatives of this combined group were stationed
at various sites throughout the PPG where major activities concentrated.
Under this method of operation in the field, individual members of the group
were not restricted to problems of their parent agency and frequently assisted other agencles in accomplishing the over-all mission of the Task
Group.
During the spring and summer of 1955, devices or weapons and experiments were added or deleted from the operation with a frequency that produced a continual revision of the test facilities required by the resulting
scientific programs. However, at the end of September 1955 it was estimated that the basic criteria necessary for the design of 95 per cent of the
scientific atructures had been transmitted to the AEC Field Mauager, Enlwetok Field Office. Ine technique employed during this period was to deI{meate items which would be required in the operation regardless of the
concept of the day.
This included items such as submarine cable systems,
gas storage building, HE magazines, standardized shot barges, and the basic
major scientific stations. This approach was necessary because the time
involved in design, procurement, and construction precluded waiting until
participation was firm and locations selected before gathering the test fectlity criteria,
By mid-September construction necessitated opening the J-6 Office !
the FA to maintain close coordination with the construction forces,
The field revisions in the shooting sequence and locations had little
effect upon the facilities required beyond the expansion of the existing capability of firing a barge shot in the Mike crater at Eniwetok Atoll.
In the course of the operation, approximately 735 scientific stations
were constructed, nearly 1300 work orders prepared, and 20 man-months of
machinist time were expended in the J-6 Shop in support of the mission of
TG 7.1.

Intra-atoll Airlift
Airlift support to the islands of Eniwetok Atoll was provided by
TG 7.4 using eight L-20 aircraft and ten H-19B helicopters. The full com-
plement of L-20 aircraft was not in place until after the arrival of the
USS Badoeng Strait on March 16, 1956.
In addition, one L-20 was in place
