The yield-to-mass ratio is the amount of weapon yield compared to the mass of the weapon. The highest achieved values are somewhat lower, and the value tends to be lower for smaller, lighter weapons, of the sort that are emphasized in today's arsenals, designed for efficient MIRV use or delivery by cruise missile systems.
A nuclear weapon [a] is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.
To find the optimum height of burst for any weapon yield, the cube root of the yield in kilotons is multiplied by the ideal H.O.B for a 1 kt blast, e.g. the optimum height of burst for a 500 kt weapon is ~1745 m. [4] An estimate of the size of the damage caused by the 16 kt and 21 kt atomic bombings of Hiroshima and Nagasaki.
The Mod 11 is a hardened penetration bomb with a reinforced casing and a delayed-action fuze; this allows the weapon to penetrate several metres into the ground before detonating, damaging fortified structures further underground. Developed from 1994, the Mod 11 went into service in 1997 replacing the older megaton-yield B53 bomb. About 50 Mod ...

The Tsar Bomba was a three-stage bomb with a Trutnev-Babaev [28] second- and third-stage design, [29] with a yield of 50 Mt. [4] This is equivalent to about 1,570 times the combined energy of the bombs that destroyed Hiroshima and Nagasaki, [30] 10 times the combined energy of all the conventional explosives used in World War II, [31] one ...
The charged particles resulting from the blast are accelerated along the Earth's magnetic field lines to create an auroral display at the conjugate point, [2] which has led documentary maker Peter Kuran to characterize these detonations as 'the rainbow bombs'. The visual effects of a high-altitude or space-based explosion may last longer than ...
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 ...
