At nearly one and a half tons, the B83 is the largest nuclear bomb that the United States currently keeps. Its nuclear tiled is 1.2 megatons—significantly more powerful than either of the nuclear bombs dropped on Hiroshima and Nagasaki during World War II. It’s big, it’s powerful, and it’s had a colorful history.
What is the most powerful nuke the US has?
The bomb was thousands of times stronger than the nukes detonated by the United States over Hiroshima and Nagasaki during World War II, and dwarfed the detonation of Castle Bravo — the most powerful nuclear weapon ever tested by the United States — which yielded just 15 megatons (13 million metric tons).

Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ).
Did the US nuke the moon?

How far away from a nuke is safe?
This will help provide protection from the blast, heat, and radiation of the detonation. When you have reached a safe place, try to maintain a distance of at least six feet between yourself and people who are not part of your household.

What would happen if a nuke went off in the ocean?
Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. … During such an explosion, the hot gas bubble quickly collapses because: The water pressure is enormous deeper than 2,000 feet.
What happens if a nuke goes off in space?
If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. … There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself.
