[53] Merchant ships carrying the munitions left Germany under Operation Golden Python and Operation Steel Box in October 1990 and arrived at Johnston Island November 6, 1990. The first launch in "Operation Fishbowl" was a successful research and development launch with no warhead.

It pumped enough radiation into the Van Allen belts to destroy or damage seven satellites in orbit. The runway was complete by December 7, 1941, though in December 1943 the 99th Naval Construction Battalion arrived at the atoll and proceeded to lengthen the runway to 6,000 feet (1,800 m).

Small releases of chemical weapon components from JACADS were cited by the EPA. [72] Many other cetaceans possibly migrate through the area, but the species being most notably confirmed is Cuvier's beaked whales. This was evidently an elaboration of the system to allow visual verification of the target before destroying it.
