ORGANIZATION AND COMMAND RELATIONSHIPS
Upon the completion of Operation Castle in May 1954, the headquarters
of TG 7.1 returned to J-Division in the Los Alamos Scientific Laboratory
and began preparations for the next Nevada operation and for Redwing. During the planning pe-iod, the organization of TG 7.1 was changed from that
used in Castle to that shown in Fig. 3.1.
The major change involved was the establishment of four Program Task
Units embodying the LASL, UCRL, BOD, and Sandia programs, and of eight
Support Task Units providing timing, firing, radivological-safety, photographic
and assembly services.
.
The Lookout Mountain photographic unit was assigned to CTG 7.4 and
a UCRL documentary photography unit was establisned.
UCRL provided two
assembly units, one for large-yield and one for small-yield devices.
The Production (H. L. Johnston) and Cambridge Corporation task units,
which existed in Castle, were no longer required and were eliminated.
A Deputy for DOD was added to the organization and was provided by
WETD of the Field Command, AFSWP.
*
During the planning phase, closc relationships were maintained with
WETD, UCRL, and SC. This was accomplished by frequent exchanges of
visits, telephone calls, correspondence, and joint participation in operations
at Nevada,
Task Unit 3 (DOD programs) did net come under the operational con-
trol of CTG 7.1 until arrival overseas on March is, 1956...
WETD and UCRL provided staff personnel who were integrated into the
J+1, J-3, and J-6 sections. WETD also provaAled staff personnel for the J-4
sestion.
In January 1956, because of the illness of Alvin C. Graves, J-Division
\eader and Deputy Commander for Scientific Matters JTF 7, W. E. Ogle,
Commander TG 7.1, became Acting Deputy Commander for Scientific Matters,
JTF 7, and Gaelen L, Felt, Group Leader of J-15 Group, LASL, became
Acting Commander TG 7.1. On May 25, 1956, these acting appointments
were made permanent.
,
Since the principal function of JTF 7 and of most of its task groups
was to support the scientific effort, much of the over-all planning depended
on the plans of TG 7.1. These in turn depended on the weapon development
plans of LASL and UCRL; and on the pregrams developed by AFSWP and
cther DOD agencies, and by SC, to participate on weapon development shots
and on shots required for other purposes,
For the above and other reasons, command relationships differed some-
what from the normal military pattern. Figure 3.2 shows the JTF 7 organization and some of the major command relationships involved.
