which country has the most powerful nuclear bomb?

Question

how powerful is it?

Answer 1

considering how the bombs are delivered is what you need to keep in mind. the bigger the bomb the bigger the blast. the soviets tested a bomb called the "tsar bomba" in the 50's that was supposed to reach 100 megatons but the actual yield was 56 megatons according to u.s. scientists. an aircraft delivered bomb usually has the biggest yield. the u.s. tested one also in the 50's that had a yield of 25 megatons. a missiles warheads are limited due to the size of the warhead and the size of the missile. the soviets ss-18 satan can have one warhead with a theoretical yield of 20-25 megatons. the u.s. minuteman III has 3 warheads with a nominal yield of 350 kilotons per warhead. most countries that have thermonuclear weapons have come to the conclusion that bigger doesn't always mean better. most icbms have warheads that have a nominal yield of around 250 kilotons. the smaller warheads are more accurate, cost less to make, and you can make more of them for the cost of the bigger ones. as of right now the russians have the biggest bomb mounted on a missile. as far as free fall bombs go, the u.s and the russians are pretty much equal in size and strength. the u.s does however possess the trident class submarine which carries 24 trident missiles with up to 8 warheads per missile with each warhead producing a nominal yield per warhead of 450 kilotons. with this you can make you own conclusions. both countries have enough to wipe the other off the map and still have leftovers for anyone else that pisses them off.

Count India out. We are the biggest bunch of losers. Even if we get 1 million N-warheads, we can't fire one. We are timid people. For centuries, India has been invaded. Today, people from any country walk to us and attack us, all those terrorists. All we do is keep watching. We are the ones to say "No first use." You bet my *** we wont use one even when we are attacked by a nuclear bomb. Peaceful nature is considered weakness in this world. Look at Iran. The one country has made Obama bend more and more towards them begging for peace. Throw a damn bomb in a country and the world will consider you powerful. Time for all those niceties are gone. The nice ones are considered weak. The devils are considered powerful.

Answer 4

the most powerful nuclear bomb was detonated by USSR. it was originally designed to have a yield of 100 megatons but later decreased it to about 80-90megatons i think because they afraid of a massive nuclear fall-out. the bomb was called "Tsar Bomba" which means emperor of all bombs in Russian and was detonated when the USSR was under the leadership of Nikita Kruschev. the bomber that carry the bomb was a specially modified TU-95 Bear. the blast can cause a 3rd degree burn to a person as far as 100km away.

how powerful is it?

Answer 6

The USSR tested the strongest ever. Off the top of my head I believe it was nearly 100 megatons, back in the early 60s. The biggest USA test was around 50 megatons.

The current stockpiles don't really have them that big, just because they target better and don't really want to destroy entire states. The biggest these days (by estimates) are around 20 - 25 megatons, but most are 5 or less.

The test treaties signed in the mid-60s after all the big ones limited testing to 150 kilotons or less, so the 50s and early 60s were the climax of the testing wars between the USSR and the USA.

Answer 7

As previously noted the most powerful tested/known about was a 100megaton by the Russians. Historically the Russians have had less accurate missiles and so went with larger warheads to ensure target destruction if they missed and the U.S. has went with smaller and more accurate delivery systems. The Russian have the most powerful warheads and largest nuclear arsenal in the world. The U.S. changing to the new isotope is not to make more powerful warheads but to decrease the amount of radioactive materials used; the mega-tonnage would be about the same but less radioactive materials used and released if one is ever set off.

Answer 8

In terms of power, once you say nuclear, there's no degree. One bomb in the 1940s wiped out a city. It's over 60 years later and every nuclear country has the capability to wipe each other off the face of the earth. It doesn't matter what particular kind of bomb it is. There are NO SMALL nuclear explosions.

Answer 9

People who don't know anything about nuclear weapons shouldn't post answers on the subject.From what I just read,that's nearly all of you.The most powerful deployed nuclear warhead belongs to Russia at 20 megatons.How powerful is that?Get a map of Denver.All of the populated,built up areas would be gone with one blast.And hey,dsm37127:the warheads on the Trident missile are considerably less in yield than 450 kilotons.It's more like 20.Let's all hope none of these things are ever used.

Answer 10

The most dangerous ICBM we ever produced was the Peacekeeper. It was a MIRVed weapon. It carried up to 10 re-entry vehicles, each tipped with a 300 kiloton warhead. What does this mean? Basically it means it had the capability to deliver 10 warheads, each capable of hitting an independent target. Only one base in the U.S. housed them. But they were deactivated a few years back. However, Minuteman III's still protect America to this day. Each one with the capability to carry up to 3 separate warheads, versus the Peacekeeper's 10.

I used to work nuke security in the military.

Just to add onto my previous post, I am fully aware the weapon I listed is not the most powerful "single" explosion. One giant nuke may take out one city, but the Peacekeeper can take out 10 cities. So the most powerful is all in how you look at it. My point is, the Peacekeeper is the most formidable ICBM we have ever put into production to protect America.
