50 Years Ago, U.S. Tested First Hydrogen Bomb

At the height of the Cold War the United States tested “Mike,” the world’s first hydrogen bomb

WASHINGTON, October 30 (IslamOnline & News Agencies) - At the height of the Cold War at 7:00 am on November 1, 1952, the United States tested “Mike,” the world’s first hydrogen bomb, on the Enewetak atoll off of the Marshall Islands.

It was a bomb unlike any one had ever seen before. The 10.4 megaton bomb was 600 times more powerful than the atomic bombs that destroyed Hiroshima and Nagasaki and ended the Japanese front of World War II in August of 1945, Agence France-Presse (AFP) reported.

The test set off an atomic mushroom cloud 12.8 kilometers wide and 43 kilometers high. It vaporized 80 million tons of earth.

“Mike” was followed by a second, more powerful test in March 1954 on the nearby Bikini atoll.

Nearly a decade earlier in July, 1945, the United States had tested the first atomic bomb in the New Mexico desert.

The culmination of what was known as the Manhattan Project, it succeeded in harnessing power by splitting the neutrons of atoms, in a process called fission.

Two types of atomic bombs were developed: enriched uranium and plutonium.

Unlike them, the hydrogen bomb, or H-bomb, does not use fission but is based on fusion of elements. That concept, first imagined in the early 1940s by Italian physicist Enrico Fermi, was technically much more difficult than fission.

The energy for that is derived from thermonuclear fusion of hydrogen isotopes.
The same energy powers the stars, and comes from heat produced by a classic nuclear explosion, liberating enormous amounts of energy and shock waves.

The story behind “Mike’s” creation is one of rivalry between world powers ... and scientists.

As Richard Rhodes detailed in his book Dark Sun: The Making of the Hydrogen Bomb, the Soviet’s first atomic test in August 1949 - aided, no doubt, by spy Klaus Fuchs - pushed the United States to up the ante: the H-bomb, dubbed the “Super” bomb by scientist Edward Teller.

Teller was involved in the birth of the atomic bombs. An American of Hungarian origins, he was the sole architect of the “Super” bomb.

Now aged 94, Teller was immortalized in popular culture as the basis of the character “Dr. Strangelove.”

Robert Oppenheimer, who led the Manhattan Project, opposed the development of the H-bomb, fearing that it might spark an arms race that could spell the end of humanity.

Sure enough, the Soviet Union, thanks to physicist Andrei Sakharov, tested its first H-bomb in August 1953.

Other world powers soon followed: Britain in 1957, China a decade later and France in 1968.

“It is very difficult now to imagine an active scenario where the H-bomb would be used, but we still have thousands,” said Michael Levi, of the Federation of American Scientists, because such a scenario would produce a holocaust.

“The U.S. arsenal of strategic nuclear weapons is completely composed of H-bombs. The same is believed for Russia,” he added.

On Tuesday, October 29, U.K. newspaper the Guardian reported that British and American academics have warned that the U.S. is developing a new generation of weapons that possibly violate international treaties on biological and chemical warfare. 

The left-wing British daily, pointed out that the claims come at a time when the U.S. is proposing military action against Iraq on the grounds that President Saddam Hussein is breaking international agreements on weapons of mass destruction.

The Guardian said that according to specialists in bio-warfare and chemical weapons, the Pentagon, with the help of the British military, is also working on “non-lethal” weapons similar to the gas used by Russian forces to end last week's theater siege in Moscow.
