Nuclear Weapons

Yes, they do. So do the Russian Federation (formerly the U.S.S.R.) and a number of other countries, including France, the U.K., China, India, Pakistan, and Israel.

The US government supplied the yellow painted metal sirens built at street corners, and emplaced anti-aircraft missile batteries into underground silos around the neighborhoods (no one knew they were there, until construction crews un-covered them when the cold war ended in 1990); school children were mandated to conduct "Duck and Cover" drills in the classroom..."at the sight of a blinding light cover your heads, ball up into the fetal position and hide under your desk." "When walking home from school, if you see a ball of fire/blinding light seek cover immediately." Home owners under there own decisions and money built BOMB SHELTERS in their back yards.

Between 150-250, but no more than 300.

The issue was "how does a military force make a move...without triggering a nuclear war...?" Hence, a cold war. A military stand-off.

The nation with nothing to lose. Where M.A.D. ( mutually assured destruction) dose not apply.

Korea was the FIRST "Limited War" (Vietnam was the SECOND) fought during the Cold War. Nuclear Weapons created the Cold War. A "Limited War" was fought with "limitations" on where the war would be fought and using only conventional weapons. Without Nuclear Weapons, the US/Allies would have probably invaded Red China, when Communist China entered the war. Which of course would have caused the Soviet Union to enter the war. Which naturally would have led to WW3. The Soviets tested their first Atomic Weapon in 1949.

Obviously two have been used in anger, but hundreds have been carried out by the Americans, Russians and the French.

Nukes have also been detonated by the UK, Pakistan, India, Israel and more recently North Korea. Together the number of nukes detonated runs into the hundreds.

The Atomic Age & Atomic Energy.

Assuming you mean nuclear weapons, at the peak both the US & USSR had well over 10000 warheads each with yields averaging in the low megaton range. After START this was cut to a bit over 1/3 that number with yields averaging just below 500 KTons. Russia has more total warheads than the US and usually higher yield, because they claim their missiles are less accurate than US missiles (probably true).

If you were referring to weapons in general, there are many billions. Maybe even more than the human population of earth.

Which gets us first will always be a big debate.

The United Kingdom has around 160 active nuclear warheads. Their arsenal is Trident-missile based, but using a british warhead design.

Secrets are part of any war, cold or hot (non-shooting or shooting); it called classified. A-Bombs made the cold war.

Not even close. The largest thermonuclear bomb ever detonated was around 57 megatons. Setting off a million of those would release about as much energy as a magnitude 9.5 earthquake. Big earthquake? Yes. Destroy the earth? No way. Now, there are probably enough to kill off all higher forms of life on the surface of the Earth either from direct damage or radiation sickness. But the Earth itself would scarcely be affected.

The GBU-43 (Massive Ordnance Air Blast, usually called a MOAB. Mother Of All Bombs) which is a 21,000 pound bomb with a blast yield of 11 tons. The U.S. Air Force Research Laboratory has stated that a larger version of the MOAB exists, weighing thirteen tons.

England is part of the United Kingdom and it does have nuclear weapons and has had them for several decades.

fission and the fusion types

depends on how big the bombs are, if they were as big as Tsar Bomba (Soviet bomb 60MT) it would take about from 15-25

no you retard it would take about 15-25 to blow the usa NT the us

it would take 10 a-bombs to kill every living thing (cuz of the radiation)

That depends on what you're referring to: The fireball radius (the nuclear explosion itself), the total anhiliation range radius, and etc.

For example, the bomb launched on Hiroshima had a fireball of several hundred feet in radius, a 1km total destruction range radius, and severe damage for miles.

For firepower bombs (nuclear bombs made for power show & not effectiveness)

The Tsar bomba of USSR had 50~55 megatons of TNT firepower, a fireball with 1km+ radius, total destruction for miles, and created a sound shockwave that could be heard in Norway/Other far Northern European areas.

Modern nuclear weapons don't have a single blast radius; the U.S. developed M.I.R.V.s (cluster nuclear bombs) that spread apart to create a shotgun blast of multiple nuclear explosions.

Armament: Six .50-cal. machine guns and ten 5 in. rockets or 2,000 lbs. of bombs.

The U.S., at its peak state, had close to 32500 nuclear weapons (about the year 1965). They now have roughly 10000.

They are taken to a plant that manufactures nuclear weapons (in the U.S. the Pantex Plant near Amarillo, Texas) where they are carefully dismantled and those parts whose materials can be reused to make new nuclear weapons are recycled. The chemical explosives are usually burned to safely dispose of them.

d Two Nuclear Bombs, one on Hiroshima, the other on Nagasaki

It hasn't sad to say. As tech advances so do the weapons, though continueing manufacture in some areas is quieter and less clear to the observer. The number of nukes has been reduced... but not by all. China builds her arsenal today without much concern for the western powers.

For the United States military, the final authority to direct the use of nuclear weapons is the President of the United States. This also requires the approval of an administrative official who has been approved by Congress.
