Both atomic bombs and hydrogen bombs are kinds of nuclear bombs, meaning that the energy comes from nuclear reactions. The big difference is that atomic bombs use nuclear fission, which splits a bigger atom into two smaller ones, to create their energy.
A discovery by nuclear physicists in a laboratory in Berlin, Germany, in 1938 made the first atomic bomb possible, after Otto Hahn, Lise Meitner and Fritz Strassman discovered nuclear fission. When an atom of radioactive material splits into lighter atoms, there's a sudden, powerful release of energy.

In a heavy-water nuclear reactor, when neutrons bombard U-238, some uranium atoms absorb an additional neutron and are transformed into Pu-239. Heavy water provides a path to turn common uranium into plutonium, one of the easily split or "fissile" materials that fuels nuclear bombs.
They needed heavy water to create a nuclear reactor, which was the stepping-stone to producing plutonium, and then an atomic bomb. The Allies did not know how far along the Germans were [in their researches] but the one thing they did know was the Nazi concentration on heavy water.
Israel crossed the nuclear threshold on the eve of the Six-Day War in May 1967. "[Prime Minister Levi] Eshkol, according to a number of Israeli sources, secretly ordered the Dimona [nuclear reactor] scientists to assemble two crude nuclear devices.
Brazil has two nuclear reactors generating about 3% of its electricity. Its first commercial nuclear power reactor began operating in 1982. Construction of the country's third nuclear power reactor is currently stalled.
By my estimation, the United States has produced approximately 66,500 nuclear weapons from 1945 to mid-2013, of approximately 100 types. [ref]Robert S. Norris and Hans M. Kristensen, “Nuclear Notebook: U.S. Nuclear Warheads, 1945- 2009,” Bulletin of the Atomic Scientists, July 2009, vol.
$2 billion - The approximate cost of research and development of the atomic bomb by the United States, called the "Manhattan Project."
Although some of the uranium came from Bear Lake in Canada 907 tonnes (1,000 tons) are thought to have been supplied by the Eldorado mining company – and a mine in Colorado, the majority came from the Congo. Some of the uranium from the Congo was also refined in Canada before being shipped to the US.
It says that the energy (E) in a system (an atom, a person, the solar system) is equal to its total mass (m) multiplied by the square of the speed of light (c, equal to 186,000 miles per second).
A key component of keeping the Manhattan Project secret was making sure Project sites were secret and secure. Each site had multiple security checkpoints that were guarded by military police twenty-four hours a day, seven days a week.

Much of the United States' stockpile of uranium ore was in the city in warehouses or on docks, arriving from the Belgian Congo. This Army establishment was called the “Manhattan Engineer District” after its location. The Army soon decided that New York City was too crowded and too close to the coast for privacy.
The scientific research was directed by American physicist J. Robert Oppenheimer. Eventually, the Manhattan Project employed more than 130,000 people and cost nearly US$ 2 billion (equivalent to US$ 23 billion in 2007 dollars).
Preliminary Organization. The story of the Manhattan Project began in 1938, when German scientists Otto Hahn and Fritz Strassmann inadvertently discovered nuclear fission. A few months later, Albert Einstein and Leo Szilard sent a letter to President Roosevelt warning him that Germany might try to build an atomic bomb.
The states of Germany are not allowed to maintain armed forces of their own, since the German Constitution states that matters of defense fall into the sole responsibility of the federal government. Germany aims to expand the Bundeswehr to around 203,000 soldiers by 2025 to better cope with increasing responsibilities.
In a regional nuclear conflict scenario where two opposing nations in the subtropics would each use 50 Hiroshima-sized nuclear weapons (about 15 kiloton each) on major population centers, the researchers estimated as much as five million tons of soot would be released, which would produce a cooling of several degrees
Only six countries—United States, Russia, United Kingdom, China, France, and India—have conducted thermonuclear weapon tests. Whether India has detonated a "true" multi-staged thermonuclear weapon is controversial. North Korea claims to have tested a fusion weapon as of January 2016, though this claim is disputed.
Canada holds contradictory positions in the world of nuclear weapons. We played an essential role in their development, but we never built any bombs of our own. No nukes are stationed on Canadian soil; however, they were for 20 years, until we finally sent the last American warheads back home in 1984.
German arms exports rose 65% from January to mid-December 2019 compared to 2018 and hit a record of €7.95 billion ($8.8 billion), according to Economy Ministry figures. Politicians from the socialist Left Party and the Greens requested the data, which has been seen by DW.
The German government quickly passed legislation to decommission all of the country's nuclear reactors, ostensibly to keep its citizens safe by preventing a Fukushima-style disaster.
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 atomic bombs, a more compact size, a lower mass or a combination of these benefits.
In practice, bombs do not contain hundreds of tons of uranium or plutonium. Instead, typically (in a modern weapon) the core of a weapon contains only about 5 kilograms of plutonium, of which only 2 to 2.5 kilograms, representing 40 to 50 kilotons of energy, undergoes fission before the core blows itself apart.
However, since any Plutonium can be used to create a bomb, no matter how unstable, Plutonium is considered the material most used in the proliferation of nuclear weapons. Its production as a by product of Uranium reactors means that harvesting it requires much less energy than creating enriched Uranium.
That's enough to build one atomic bomb, if the uranium is further refined to make it weapons-grade — a process that could take just two to three months , says David Albright, a nuclear-policy specialist at the Institute for Science and International Security in Washington DC.
Hydrogen bombs cause a bigger explosion, which means the shock waves, blast, heat and radiation all have larger reach than an atomic bomb, according to Edward Morse, a professor of nuclear engineering at University of California, Berkeley.
It is reported that designs least as small as 105 mm (4.1 inches) are possible. A hypothetical 105 mm system developed for use in an artillery shell would be about 50 cm (20 inches) long and weigh around 20 kg. Compact nuclear artillery shells (208 mm and under) are based on a design approach called linear implosion.
America's ICBM force has remained on continuous, around-the-clock alert since 1959. The Ground-Based Strategic Deterrent program will begin the replacement of Minuteman III and modernization of the 450 ICBM launch facilities in 2029.
A hydrogen bomb is a type of nuclear bomb, just like an atomic bomb, where the explosive energy comes from as nuclear reaction. The energy released by fusion is three to four times greater than the energy released by fission, giving the “hydrogen” bomb, or H-bomb, more power.
As of the beginning of 2019, the global stockpile of highly enriched uranium (HEU) was estimated to be about 1335 metric tons. The global stockpile of separated plutonium was about 530 tons, of which about 310 tons was civilian plutonium.
