Ivy Mike was the codename given to the first full-scale [note 1] test of a thermonuclear device, in which a significant fraction of the explosive yield comes from nuclear fusion. [ 1 ] [ 2 ] [ 3 ] Ivy Mike was detonated on November 1, 1952, by the United States on the island of Elugelab in Enewetak Atoll , in the now independent island nation ...
The first Ivy shot, codenamed Mike, was the first successful full-scale test of a multi-megaton thermonuclear weapon ("hydrogen bomb") using the Teller-Ulam design.Unlike later thermonuclear weapons, Mike used deuterium as its fusion fuel, maintained as a liquid by an expensive and cumbersome cryogenic system.
Ivy Mike, the first full test of the Teller–Ulam design (a staged fusion bomb), with a yield of 10.4 megatons (November 1, 1952). The Teller–Ulam design is a technical concept behind modern thermonuclear weapons, also known as hydrogen bombs.
For two thermonuclear bombs for which the general size and primary characteristics are well understood, the Ivy Mike test bomb and the modern W-80 cruise missile warhead variant of the W-61 design, the radiation pressure was calculated to be 73 × 10 ^ 6 bar (7.3 TPa) for the Ivy Mike design and 1,400 × 10 ^ 6 bar (140 TPa) for the W-80.

The Mark 16 nuclear bomb was a large American thermonuclear bomb (hydrogen bomb), based on the design of the Ivy Mike, the first thermonuclear device ever test fired.The Mark 16 is more properly designated TX-16/EC-16 as it only existed in Experimental/Emergency Capability (EC) versions.
And indeed, it was 70 years from the first successful re-creation of fusion—the detonation of a thermonuclear device codenamed Ivy Mike, in 1952—to NIF’s successful ignition reaction.
This was the premise behind the Ivy Mike bomb. The detonation of Ivy Mike by the United States prompted Soviet retaliation, and the Soviets quickly attempted to catch up. Although the Soviet Union had detonated their RDS-6 around that same time, the RDS-6 was initiated by high-powered explosives, while Ivy Mike was initiated by radiation method ...
The Runt device. The Runt TX-15 device was a weaponized dry fusion bomb, using lithium deuteride fuel for the fusion stage of a staged fusion bomb, unlike the cryogenic liquid deuterium of the first-generation Ivy Mike fusion device.
