The device, codenamed Mike, was 20 ft high, 6 ft 8 in wide, and weighed 140,000 lb. Too large to be deployed as a weapon, it was built solely to demonstrate the power of a fusion explosion. It was detonated on Elugelab Island in the Enewetak (or Eniwetok) Atoll of the Marshall Islands. It yielded 10.4 megatons of explosive power, over 450 times the power of the bomb that fell on Nagasaki. The detonation obliterated Elugelab, leaving an underwater crater 6240 ft wide and 164 ft deep where an island had once been.
The Band existed between May 1987 and May 1989. They released an EP ("Hectic", January 1988) and a 12-inch record titled "Energy" on Lookout! Records in March, 1989, shortly before they split.
