OPERATION ARGUS.
'
ARGUS, the code name for the only atmospheric nuclear test operation in
the Atlantic Ocean, consisted of the three high-altitude, low-yield
detonations identified below.
The nuclear devices were lifted to about a
300-mile altitude by rockets fired from the missile trials ship USS Norton
Sound (AVM-1), one of the nine ships participating in the series (20: 1).
The operation was based in the Atlantic at about 45° south latitude.
The
location placed the task force outside regular shipping lanes but kept the
launch well within the range of U.S. military forces required for support of
ARGUS scientific projects (20: 19).
