OPERATION HARDTACK I.
HARDTACK was the designation for U.S. nuclear testing in both the Pacific
and in Nevada during 1958.
Phase I, discussed in this section, consisted of
34 Pacific nuclear detonations, which was as many as had been fired in all
prior oceanic tests.
The series encompassed a wide variety of events, as
indicated in the accompanying table (19: 23,24).
All but two of the detonations were at Enewetak and Bikini Atolls in the
Marshall Islands.
TEAK and ORANGE, high-altitude detonations, occurred 42 and
76 kilometers over Johnston Island, which lies about 700 nautical miles westsouthwest of the Hawaiian Islands.
A Honolulu resident described the TEAK
burst, which took place 10 minutes before midnight, in a front-page story for
the 1 August Honolulu Star-Bulletin (19: 1,266):
I stepped out on the lanai and saw what must have
been the reflection of the fireball. It turned from
light yellow to dark yellow and from orange to red.
The red spread in a semi-circular manner until it
seemed to engulf a large part of the horizon.
A cloud rose in the center of the circle.
