Thermonuclear weapons leverage fusion and fission to increase destructive capacityĬastle Bravo hydrogen bomb test (D.O.D. That means Russia’s newest ICBM has approximately 3,300 times the destructive power of the bomb dropped on Hiroshima. Russia’s latest ICBM, the RS-28 Sarmat II, is said to have an explosive yield of 50 megatons.įifty megatons are the equivalent of 50,000 kilotons, or 50,000,000 tonnes of TNT. As incredible as that is, it’s practically minuscule compared to some of the massive thermonuclear weapons in service today. The atomic bomb dropped on Hiroshima in 1945 had an explosive yield of 15 kilotons or 15,000 tonnes of dynamite. This unchecked chain of fission reactions causes the huge explosion we’re familiar with from atomic test footage. In some weapons, the split also releases two or more neutrons which then strike other isotopes, splitting them and creating a chain of fission reactions until all of the fissionable material is expended. When split, these isotopes release a huge amount of thermal energy (heat) and gamma radiation. In most atomic bombs, this is accomplished by having a neutron strike the nucleus of either a uranium-235 or plutonium-239 isotope. In its simplest terms, nuclear fission is the process of splitting one larger atom into two or more smaller ones. ![]() Atomic bombs, sometimes referred to as atom bombs, leverage a physical process known as nuclear fission to release huge amounts of destructive energy. photo)Ītomic bombs are the original nuclear weapons — first developed by the United States with allied support during World War II within a program known as the Manhattan Project. Atomic bombs are the precursors to thermonuclear weapons July 16, 1945, on a remote 18-mile by 24-mile portion of the Alamogordo Bombing and Gunnery Range northwest of then-Alamogordo Army Air Field, N.M. While atomic bombs are capable of delivering huge amounts of destruction, they actually pale in comparison to the firepower found inside thermonuclear weapons — which are also commonly referred to as hydrogen bombs. In recent months, Russian officials have made a number of veiled (and less-than-veiled) nuclear threats that may have left some wondering, what exactly is the difference between an atomic bomb and a modern thermonuclear weapon like those carried by Russia’s ICBMs?Īt a very practical level, the most important difference is in their destructive capacity.
