In 1958 the U.S. Norton Sound participated in Operation Argus. From south of the Falkland Islands she launched three rockets carrying low-yield atomic warheads. Detonations occurred at altitudes between 160 and 750 km, and effects were monitored by the Explorer IV satellite and other instrumented rockets. Analysis of the data contributed to the discovery of the Van Allen radiation belt.
