Site Geometry
Toe transaitter missile array for Teak sbor is sbown fin Fig. 7.1, and
for Orange in Fig. 7.2.
Eigat cwo-stage missiles, either the Descon-arrow
or the Viper-arrow combinatisa, were set for launch on each shot.
Their
laumch times were variously related ta Redstone launch as tabulated below and
in Tables 7.1 and 7.2.
Launch azimuths of the missiles were carefully deter-
zioed in an attempt to optimize their positions im space consistent with the
following Sbamdary coalitions:
.
(1) Line-of-sight transmitter stations to receiver stations mist penetrate the center of the burst as well as the anticipated fringe areas of total
Slackcur.
(2) Plamaed point of detonation:

(3) For Teak, there was a minimm 5-degree separation in azimuth between
the nearest transmitter missile trajecypry and the Redstone trajectory.

Eight concrete launcher pads, 6 feet square and 6 inches
thick, were constructed along the southern shore of Johnston Island.
A small
zero-length Laumcher mounted on each pad was used to direct the missiles along
the calculated trajectories.
Identification of launchers, launch azimuths, and
frequency of each transmitter aissile are tabulated in Tables 7.1 and 7.2.

Receiving Stations.
(Station Yo. J ~ 3250.01).
One receiving station was located on Johnston Island
The other station was located in a trailer on the
USS Belle Crove (Station So. J-3230.02).
°
The ship was positioned approziastely
on an azimuth 080” IN from Johnston Island, 30 miles away, during Teak, and
030° TS, 25 miles avay, during Orange.
