Which country exploded its first underground nuclear device?
Many, but the US Buster-Jangle Uncle effects test was the first. It was 1.2KTons exploded at a depth of about 3 feet, to test cratering effects. It produced massive fallout levels. Most underground testing is done much deeper to prevent contamination.
How many miles can a nuclear bomb cover?
You have asked a question that though appearing very simple has an enormously complex answer that I can only summarize here. Much of the basic info can be obtained from the book The Effects of Nuclear Weapons, edited by Samuel Gladstone, and has been reprinted in many updated editions by the US government. Some of the variables that must be considered are:
- Yield
- Burst height/depth
- Exact effect being considered (e.g. blast, thermal. radiation, fallout, EMP)
- Weather conditions
- Terrain
- Building construction
- If burst is subsurface, material around burst (e.g. dirt, rock, concrete)
- etc. etc.
Without answers to these variables no actual answers can be given. However to give some ideas, for a low yield bomb just considering prompt radiation effects they might only cover a radius of a couple hundred yards around ground zero (blast and thermal would be larger, EMP would be negligible), while for a high yield bomb exploded in the ionosphere just considering EMP effects they might cover a radius of 1000 to 2000 miles around ground zero (all other effects would be negligible).
How many nuclear weapons does the United States have?
The exact number is highly classified. It would be classified as Top Secret information. Both sides kept such things secret, while making it obvious to the other that the number is substantial.
The nuclear arms reduction treaties such as START do not restrict the number of weapons, only the number of vehicles (missiles, bombers) that can deliver them to their target. Many older nuclear weapons and missiles have been removed from service under various treaties.
When was the first nuke bomb invented?
During World War 2, Developed by a team of scientiests in the United States, code named the Manhattan Project.
From 1942 to 1946
Were nuclear weapons used in the cold war?
as you have been getting that message are they the same questions asked well no. you see they ask for countries, and this asks for just were there nuclear weapons? No there was not any nuclear weapons just threatening
Which best describes the nuclear arms race?
The hydrogen bomb was much more powerful than the fission bomb. Sputnik sparked fears of Soviet bombs traveling on rockets. The United States and the Soviet Union both scrambled to make as many bombs as possible.
How many nuclear bombs have been fired?
maybe thousands, except for the two used in WW2, all were tests.
Which nation has the most nuclear bombs?
Russia currently owns the biggest stockpile of nuclear weapons in the world. Also Russia made and detonated the biggest nuclear bomb in history called the Tsar bomb.
Has anyone rode a nuclear weapon?
Slim Pickins, in the movie "Dr. Strangelove, or How I Learned to Stop Worrying and Love the Bomb." I'm not aware of any real-life examples.
When was nuclear testing finally stopped?
August 5th, 1963 Three of the four nuclear powers sign a limited treaty that bans most, but not all, nuclear weapons testing.
The 1963 treaty only banned "Atmospheric" tests (in the air, space, and underwater) not "most". Testing just moved underground and continued at about the same pace, maybe even faster for a while.
Is Korea going to nuke America?
Most likely not, considering the fact that North Korea's nukes won't be that devastating to America. Even when the North Korea lunches a nuke, America is going to show a massive retaliation, firing loads and loads of nukes onto Korea which will result in catastrophic annihilation of not just the North Korea, but also South Korea and parts of China, and possibly parts of Japan and Russia. With all the risks present, it is highly unlikely that North Korea is even going to attempt to lunch nukes at America.
What country has the most nuclear arsenal in the world?
Russia has the largest arsenal, followed by the United States.
Statistics
Russia has the most, with at least 16,800 nuclear weapons. The USA is in second with at least 9,600. I should point out that North Korea has about 5. Compare that to the number the US has and ask yourself it it's logical for the US to protest NK nukes.

Who developed the first nuclear bomb?
U.S., in Manhattan Project, technical director J. Robert Oppenheimer, manager General Leslie R. Groves, and a cast of thousands (including my grandfather A.A.C., who as an ordinary construction worker with no clearance at all, at Hanford, Washington, observing some of their strange activities later repeatedly made the statement: "I can't understand how our government can be so wasteful in time of war, they repeatedly dug huge trenches, filled them with perfectly good usable jeeps, office equipment, and other things then buried them. What a waste!")
What US policy required greater dependence on nuclear weapons and the airplanes that delivered them?
Brinkmanship
When was the first controlled nuclear explosion in the US?
Nuclear explosions are not controlled. Nuclear reactors are controlled.
The first controlled nuclear reaction in the US was on December 2, 1942.
The first nuclear explosion in the US was on July 16, 1945.
Why countries want the nuclear weapons?
they want em so they can feel powerful and bomb other countries tht have em and threaten people tht theyll bomb u if u dont do this or thatType your answer here...
What nuclear weapons were used in cold war?
No Nuclear weapons were used during the cold war. The cold war was a stand off between soviet Russia and America, where they treated either with a lot of suspicion and distrust. However, it was not a 'War' in the literal sense of the word.
Why weren't nuclear weapons used in the Vietnam war?
The US did not want to risk a nuclear confrontation with the communist superpowers.
When was the last time that nuclear weapons were used?
The last time they were used in the act of war? Hiroshima and Nagasaki.
But countries still test out their nuclear arms at certain bases. I recall hearing news of North Korea testing out their nukes:
North Korea was a Party to the Nuclear Non-Proliferation Treaty, but announced a withdrawal on January 10, 2003, after the United States accused it of having a secret uranium enrichment program and cut off energy assistance under the 1994 Agreed Framework. The last time they tested out their nukes was in 2006.
