The atomic bombs that hit Japan were huge and had to be dropped from planes flying overhead. This 1960 image released by the US Department of Defense shows the Little Boy atomic bomb, the type detonated over Hiroshima on August 6, 1945. A typical hydrogen bomb is two-stage: First, an atomic fission bomb detonates, and that in turn starts the fusion of a hydrogen isotope in a second section. H-bombs are also known as thermonuclear bombs, because of the extremely high temperature needed to induce fusion. It’s the same process that keeps the sun and other stars burning. The hydrogen bomb uses both fission and fusion - the fusing together of atomic nuclei - to produce more explosive energy. Experts believe the yield of North Korea’s latest test was at least 140 kilotons, which would make it some seven to eight times as powerful as Hiroshima (15 kilotons) and Nagasaki (about 20).Ītomic bombs rely on fission, or the splitting of the nucleus of an atom, just as nuclear power plants do. Their yields of 10,000 kilotons and more were several hundred times larger than the bombs that levelled Hiroshima and Nagasaki. The US conducted the first successful tests of hydrogen bombs in the 1950s. ![]() This undated picture released by North Korea's official Korean Central News Agency (KCNA) shows North Korean leader Kim Jong-Un (C) looking at a metal casing with two bulges at an undisclosed location.(AFP Photo)Ī hydrogen bomb can be far more powerful than the atomic bombs the US dropped on Japan in World War II. If true, it would represent a major step forward in North Korea’s effort to develop a nuclear weapon capable of reaching the United States. Outside experts haven’t been able to verify that claim, but say it’s plausible.
