Whats the yield of the largest H bomb explosion possible?

Question

what would the yield be and how much destruction you think it would cause also how would it be made i know making a bomb on that scale would be hard work

Answer 1

I have wondered too, over the years.I'm a babyboomer, and had to deal with the horrible time of air raid sirens, bomb shelters, nightmares as a young kid,etc. the 50 plus ans is correct (underground) the limit? Does it matter except to guys like us, curious? Who knows. I do know this, however: when the first a-bomb was tested back in the 40's, the developers were not certain of the effects. They actually admitted years later that the chain reaction might not have stopped at all, thus burning Earth's atmosphere away. Scary, huh? Wonder what else they (gov't) aren't telling us?--Great ques.-- rat

Answer 2

There is no upper limit. The USSR set off a 58 megaton explosion many years ago, and in principle one could go considerably larger. But any weapon that big is too large to be deliverable by any reasonable means, and since the radius of destruction is proportional to the cube root of the explosive yield, large weapons are uneconomic. The largest weapon the US ever had was rated at about 20 megaton yield, and current weapons range in size up to a few hundred kilotons.

With every day pass, our country is getting into more and more trouble. The inflation, unemployment and falling value of dollar are the main concern for our Government but authorities are just sleeping, they don’t want to face the fact. Media is also involve in it, they are force to stop showing the real economic situation to the people. I start getting more concern about my future as well as my family after watching the response of our Government for the people that affected by hurricane Katrina.

Answer 4

You need only to look to the big, orange ball of fire in the sky for your answer. What do you think is going on in the Sun? There are even larger stars than our Sun that are also nuclear fusion reactors. They are controlled explosions that make our lives possible.

Answer 5

Proved: 57 megatons Russia

Theoretical?
The sky is the limit I remember reading in the guiness book years ago about a cobalt sprinkled device the US had or drew up that was 28 000 megatons and called "Doomsday"

Although that was probably just cold war propaganda...

Answer 6

It doesn't answer your question but a nuclear sub carries more firepower than all the explosives used in WWI,WW2 and conflict's up to date.

Answer 7

dont kno the biggest but i know the bombs today are about 700 times stronger then the first h-bomb.

check out this site, great read on bombs

Answer 8

Enough to land your tush, or what's left of it, on Mars. The question isn't how big is possible, but how big is practical for warfare.
