When Operation Ivy (ivy English for Ivy ) were two American nuclear testing referred Ivy Mike and Ivy King . Both tests were carried out by Joint Task Force 132 in the Pacific on Eniwetok Atoll in 1952 .
The previous series of nuclear weapons tests was Operation Tumbler-Snapper , the subsequent Upshot-Knothole .
The individual tests of Operation Ivy
Ivy Mike
→ Main article: Ivy Mike
Ivy Mike was the first hydrogen bomb and had an explosive force of 10.4 megatons TNT equivalent . The bomb was detonated because of its weight on the ground. Ivy Mike was the fourth largest atomic bomb tested by the US. The island of Elugelab disappeared completely, the surrounding islands were destroyed by the fireball and the pressure waves up to 10 kilometers away. Instead of the island of Elugelab, there was a crater in the reef, over 3 kilometers in diameter and 60 meters deep. A total of around 80 million tons of earth were thrown up.
Ivy King
Ivy King was a smaller nuclear weapon that was dropped from an airplane. Although it was not a hydrogen bomb (i.e. no nuclear fusion took place), an explosive force of 500 kilotons was achieved. This made Ivy King very strong for its design. King was detonated because the US military demanded a large nuclear fission bomb as the success of the developed hydrogen bomb Mike was uncertain. France later optimized pure nuclear fission bombs up to 800 kT, which is probably the maximum.
