The bomb was code-named “Ivy Mike”. It was the first test of the Teller-Ulam bomb design, which produced yield estimated in the range of 10.4–12 Megatons (450 times as powerful as the Nagasaki bomb) when it was detonated on Elugelab Island in the Enwetak Atoll, in the Ralik chain of the Marshall Islands.
It was the first successful Hydrogen Bomb test by either side, the first fusion bomb, and the acquisition of this technology by the United States marked an escalation in the arms race of the Cold War – a little over nine months later, the Soviet Union would detonate a fusion bomb of its own.
