A thermonuclear weapon, fusion weapon or hydrogen bomb (H-bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a …

6 天之前 · Thermonuclear bomb, weapon whose explosive power results from an uncontrolled self-sustaining chain reaction in which isotopes of hydrogen combine under high temperatures to form helium in a process known as nuclear fusion.

2017年9月22日 · North Korea is threatening to test a hydrogen bomb, a weapon more powerful than the atomic bombs that devastated the Japanese cities of Nagasaki and Hiroshima during World War II. Here's how they...

2023年8月17日 · Hydrogen bombs are the most powerful explosive weapons that exist. Its power is measured in equivalent terms of tons of TNT, a conventional unit of explosive energy. Fusion bombs can have output on the megaton scale, meaning they can release the energy equivalent of millions of tons of TNT.

Bravo was a device using Lithium Deuteride as its fuel and the explosion yielded 15 megatons, the largest bomb ever exploded by the United States. The bomb was in a form readily adaptable for delivery by an aircraft and was thus America’s first weaponized hydrogen bomb.

hydrogen bomb, or H-bomb or thermonuclear bomb, Weapon whose enormous explosive power is generated by the nuclear fusion of hydrogen isotopes. The high temperatures required for the fusion reaction are produced by detonating an atomic bomb …

While the atomic bombs built during the Manhattan Project used the principle of nuclear fission, the thermonuclear, or hydrogen, bomb was based upon nuclear fusion. While fission is most easily achieved with heavy elements, such as uranium or …

4 天之前 · On January 31, 1950, Truman announced that he had directed the AEC to continue its work on all forms of nuclear weapons, including hydrogen bombs. In the months that followed Truman’s decision, the prospect of building a thermonuclear weapon seemed less and less likely.

2022年11月18日 · Thermonuclear weapons, sometimes referred to as Hydrogen, or “H-bombs,” utilize both atomic fission and nuclear fusion to create an explosion. The combination of these two processes releases massive amounts of energy, hundreds to thousands of times more powerful than an atomic bomb.

2018年5月17日 · hydrogen bomb (H-bomb) Nuclear weapon developed by the USA in the late 1940s, and first exploded in 1952 in the Pacific. The explosion results from nuclear fusion when hydrogen nuclei are joined to form helium nuclei, releasing great destructive energy and radioactive fallout. An atomic bomb is used as the trigger.
