The remaining bomb casings are located at the Russian Atomic Weapon Museum in Sarov and the Museum of Nuclear Weapons, All-Russian Scientific Research Institute Of Technical Physics, in Snezhinsk. Tsar Bomba was a modification of an earlier project, RN202, which used a ballistic case of the same size but a very different internal mechanism. [16]
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
RDS-37, 3 megaton bomb, the first Soviet two-stage hydrogen bomb, tested 22 November 1955; RDS-220 Tsar Bomba an extremely large three stage bomb, initially designed as a 100-megaton-bomb, but was scaled down to 50 megatons for testing. Intercontinental Ballistic Missiles. RDS-9, 40 kiloton warhead [3] for R-5M MRBM (SS-3)
Mark 41 thermonuclear bomb casing at the National Museum of the United States Air Force. The B-41 (also known as Mk-41) was a thermonuclear weapon deployed by the United States Strategic Air Command in the early 1960s. It was the most powerful nuclear bomb ever developed by the United States, with a maximum yield of 25 megatons of TNT (100 ...
As a point of comparison in the chart below, the most likely nuclear weapons to be used against countervalue city targets in a global nuclear war are in the sub-megaton range. Weapons of yields from 100 to 475 kilotons have become the most numerous in the US and Russian nuclear arsenals; for example, the warheads equipping the Russian Bulava ...
While both the US and Soviet Union investigated (and in the case of the Soviets, tested) "very high yield" (e.g. 50 to 100-megaton) weapons designs in the 1950s and early 1960s, [66] these appear to represent the upper-limit of Cold War weapon yields pursued seriously, and were so physically heavy and massive that they could not be carried ...
The yield varies for a tactical nuclear weapon from a fraction of a kiloton to approximately 50 kilotons. [7] In comparison, a strategic nuclear weapon has a yield from 100 kilotons to over a megaton, with much larger warheads available. [7]
As of 2013 the Pentagon saw the B83 nuclear bomb as a "relic of the Cold War," believing that deploying a megaton-yield gravity bomb, the highest level nuclear weapon left in the U.S. inventory, to Europe was "inconceivable" at this point. It can also only be carried by the B-2 bomber, and integrating it onto additional aircraft would be costly.
