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 lower mass, or a combination of these benefits.
After Truman ordered the crash program to develop the hydrogen bomb in January 1950, the Boston Daily Globe published a cutaway description of a hypothetical hydrogen bomb with the caption Artist's conception of how H-bomb might work using atomic bomb as a mere "trigger" to generate enough heat to set up the H-bomb's "thermonuclear fusion" process.
The United States conducted six atomic tests before the Soviet Union developed their first atomic bomb and tested it on August 29, 1949. Neither country had very many atomic weapons to spare at first, and so testing was relatively infrequent (when the U.S. used two weapons for Operation Crossroads in 1946, they were detonating over 20% of their ...
From those pipes, mirrors would reflect early bomb light from the bomb casing to a series of remote high-speed cameras, and so that Los Alamos could determine both the simultaneity of the design (i.e. the time interval between primary's firing and secondary's ignition) and the thermonuclear burn rate in these two crucial areas of the secondary ...
The Tsar Bomba (Russian: Царь-бомба, romanized: Tsar'-bomba, IPA: [t͡sarʲ ˈbombə], lit. ' Tsar bomb '; code name: Ivan [5] or Vanya), also known by the alphanumerical designation "AN602", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested.
Developed between 1956 and 1961 as the Soviet Union engaged in a nuclear arms race with the United States, the Tsar Bomba - the King of Bombs - was the largest hydrogen bomb ever and was claimed ...
North Korea said on Sunday it has developed a more advanced nuclear weapon that has "great destructive power."
North Korea's claim of a successful H-bomb test marks a big step in its long-stated goal of developing a nuclear missile that puts the U.S. within range. Possible two-stage hydrogen bomb seen ...
