reef near Johnston Island. Many of the parts were recovered by skin diving
and the type of failure was deduced, if not the primary cause,
2.
The
-
Maem beacon carrying rockets failed at first-
stage burnout and fell back onto the western half of Johnston Island.
A sub-
sequent test firing verified this failure.
3.
The displaced burst point was outside the beam of the antenna re-
ceiving the 4 KMc diagnostic signal and no information was received, The
signal, though weak, was seen at the recelving station,and operation of this
system was verified by the 200 Mc monitor telemetry.
4.
Two of the instrument carriers, the 50,000- and 80,000-ft stations
were not recovered, The RF signals indicated the chutes operated satis-
factorily, but the long time spent in searching for other nose cones and pods
may have allowed these two noses to take on water and sink.
The displaced burst caused the stations to be considerably outside of
the intended {nterest areas, but it appears that most of the desired data will
be forthcoming from the records and the four recovered noses.
The amount
of optical data lost has not been determined at this time.
After Teak, Program 32 was asked to participate in the Orange shot to
a larger extent than was originally intended.
No attenuation measurements
or instrument carriers were originally scheduled for Orange.
The measurements and instrumentation actually attempted on Orange
test are as follows:
1.
Four radchem samplers.
2.
Three instrument carriers, one at 80,000 ft altitude and 95,000 ft
horizontally displaced from the burst, and two at burst altitude, one 40,000 ft
north and one 40,000 ft west of air zero.
3.
Eight Deacon-Arrow
RF attenuation rockets.
4.
MIDOT tracking of the three instrument carriers, two of the beacon
carriers, and the Redstone.
5.
The 4 KMc diagnostic measurement.
6.
Photo coverage as on Teak plus documentary coverage from French
Frigate Shoals.
7.
Warhead.
-
Equipment operated and results were obtained as follows:
1. The four samplers were recovered, but only the sample collected
40 sec after burst contained any activity. Analysis by LASL will determine
if this was adequate.
~ "2
Telemetered data from the three instrument carriers appears satisfactory. The station 40,000 ft north of the burst was not recovered.
3.
Only seven RF attenuation rockets were fired. Three 225 Mc sys-
tems recorded good data. The 1500 Mc results are not yet known.
4.
MIDOT tracking was good.
5.
The 4 KMc diagnostic measurements gave transit time and may
give a figure for early alpha.
6.
The photo coverage was lost because of cloud coverage.
7.
The warhead apparently operated as expected.
