Operation Ivy

Operation Ivy was the eighth series of American nuclear tests coming after Tumbler-Snapper and before Upshot-Knothole. The two explosions were staged in late 1952 at the Pacific Proving Ground.

The first device, codenamed Mike, was 20 ft (6 m) high, 6 ft 8 in (2 m) wide, and weighed 140,000 lb (63.5 t), and was the first hydrogen bomb based on the Teller-Ulam configuration. Too large to be deployed as a weapon, it was built to demonstrate the power and possibility of using nuclear fusion as a principle for larger-yield nuclear weapons than previously possible. It was detonated on Elugelab Island in the Enewetak 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 6,240 ft (1.9 km) wide and 164 ft (50 m) deep where an island had once been.

Operation Ivy was a ska punk band who originated from the East Bay of San Francisco. Two of their members, Tim Armstrong ("Lint") and Matt Freeman, went on to form the band Rancid.

The band existed between May of 1987 and May of 1989. They released an EP (Hectic, January 1988) and a 12 inch record titled Energy on Lookout! Records in March 1989 shortly before they disbanded.
