Abstract: This is a report on the instrumentation for Projects 1.2a, 1.3,
and 1.7 of Operation CASTLE. This instrumentation was devised to
measure pressures, shock winds, and ground accelerations from large
scale detonations. Project 1.2a measured pressures less than 75 psi,
Project 1.3 recorded shock winds, and Project 1.7 was concerned with
close-in ground accelerations. In addition to the formal
instrumentation program field tests of several new type gages were
made. All new gages had had laboratory tests but field tests were made
to insure that the gages would perform under actual operating
conditions.
Records were taken on 112
information channels.
Of these,
99 gave good information, six gave information up to arrival of the
shock wave and seven gave no information.;

Abstract: The objective of Project 6.1 (CASTLE) was to determine whether
the equipment-operating procedures used in obtaining radar scope photos
for IBDA (Indirect Bomb Damage Assessment) of previous A-bomb tests
were valid for thermonuclear weapons. The procedures for obtaining the
radar photos involved positioning of bombers at a safe distance from
ground zero at operational altitudes, with radar scanning ground zero
during, and immediately after, the weapon burst. The photography
obtained on each shot was generally good. The conclusions are that a
high yield weapon burst can be readily detected by the bomber’s radar,
and that present equipment-operating techniques are adequate. These
conclusiong must be qualified.;
