Nuclear Weapons Test-Ivy-Mike 10.4mt
Ivy Mike was the codename given to the first US test of a fusion device
where a major part of the explosive yield came from fusion. It was detonated on
November 1, 1952 by the United States at 11.6709 N, 162.1980 E on Enewetak,
an atoll in the Pacific Ocean, as part of Operation Ivy. The device was the first full test
of the Teller-Ulam design, a staged fusion bomb, and is generally considered the first
successful test of a hydrogen bomb.
Due to its physical size and fusion fuel type (cryogenic liquid deuterium) the Mike device
was not suitable for use as a thermonuclear weapon; it was intended as an extremely
conservative experiment to validate the concepts used for multi-megaton detonations.
A simplified and lightened bomb version (the EC-16) was prepared, and scheduled to be
tested in operation Castle Yankee, as a backup in case the non-cryogenic "Shrimp"
fusion device (tested in Castle Bravo) failed to work; that test was cancelled when
the Bravo device was tested successfully, making the cryogenic designs obsolete.
Nuclear Weapons Test-Castle-Bravo 15mt
Castle Bravo was the code name given to the first U.S. test of a so-called dry fuel
thermonuclear device, detonated on March 1, 1954 at Bikini Atoll, Marshall Islands,
by the United States, as the first test of Operation Castle (a longer series of tests of
various devices). Unexpected fallout from the detonation—intended to be a secret test—
poisoned the crew of Daigo Fukuryū Maru ("Lucky Dragon No. 5"), a Japanese fishing boat,
and created international concern about atmospheric thermonuclear testing.
The bomb used lithium deuteride fuel for the fusion stage, unlike the cryogenic liquid
deuterium used as fuel for the fusion stage of the U.S. first-generation Ivy Mike device,
which, being the size of a small office building, was an impracticable weapon for use at war.
The bomb tested at Castle Bravo was the first practical deliverable fusion bomb in
the U.S. arsenal.
The Soviet Union had previously used lithium deuteride in a nuclear bomb,
their Sloika (also known as Alarm Clock) design, but since it relied on using
the initial fission explosion to compress, inertially confine, and ignite the fusion fuel,
its yield was limited (400 kt) in comparison to the Teller-Ulam-based Ivy Mike (10.4 Mt)
and Castle Bravo (~15 Mt). Mike and Bravo both used the Teller-Ulam design,
which featured separation of the fusion device from the fission device, and used
radiation pressure (or probably radiation-induced ablation of the heavy tamper
surrounding the fusion device) to produce staged-radiation implosion and fusion ignition
of a much greater magnitude. After a few years, the Soviets, led by Andrei Sakharov,
independently developed (Sakharov's Third Idea) and tested (RDS-37) their first
Teller-Ulam device in 1956.
Though some 1,000 times more powerful than the atomic bombs which were dropped
on Hiroshima and Nagasaki during World War II, it was considerably smaller than
the largest nuclear test conducted by the Soviet Union several years later,
the ~50 Mt Tsar Bomba.
