Nuclear Weapons

yes

No, it was invented in London in 1933 and built in Los Alamos, NM in 1945.

Only in World War Two and only two were ever dropped (both on Japan) Then we got the cold war and the whole mutually assured destruction so no one else has done anything besides test and stockpile nuclear weapons.

The fundamental unit for all types of energy is the Joule, and this is related to power as 1 Watt = 1 Joule/sec. Output power of a nuclear reactor is measured in Watts, or for large power reactors in MegaWatts, and would typically be around 3000 MW. That is the thermal output of the reactor, when coupled to a Rankine cycle steam/generating plant this would produce about 1000 MW electrical.

{| |- | The exact number probably remains highly classified. Both sides kept such things secret, while making it obvious to the other that the number was substantial. Many of the weapons have been destroyed, but more than enough remain to devastate life on Earth as we know it. |}

Do you have one for sale?

Honestly, not much. The primary squad weapon of World War 2 was the rifle, usually bolt-action (with the exception of the American M1 Garand); often, the squad would have a light machine gun (such as the American BAR, or the British Bren gun), and one or two submachine guns, such as the German MP40 or American "Tommy Gun" Thompson .45 submachine gun. There was little in terms of squad-based demolitions outside of hand grenades, plastic explosive for demolition, and limited anti-tank weapons (such as the infamous "Bazooka"). There was significant armored support of infantry, as well as artillery support. Towards the end of WW2, the Germans began research of what an infantry soldier really needed; they found that most engagements took place within 300 meters, and that the bolt-action rifle and the submachine gun were extremely disadvantaged when taken out of their respective areas of expertise; they devised a hybrid, what Hitler christened the Sturmgewehr (assault rifle), that enjoyed enormous success. The assault rifle is THE commonly accepted infantry rifle pattern in the modern day.

In the Iraq War (assuming you mean the recent one, not the Second Gulf War), the initial assault of Hussein's forces was done by coordinated airstrikes and advanced troop-carried missile launcher systems and mortar teams. The counterinsurgency effort, taking place after the overthrow of Saddam, meant that the massive shock-and-awe strategy would endanger civilians (now a necessary part of defeating the insurgency); a more precise strategy is being used. The war is now being fought primarily by infantry, rooting out insurgent nests with tips from civilians, and preventing insurgents from terrorizing civilians into submission to their cause (not terrorism. different thing). And so, the war is mainly fought with infantry rifles; the American forces using AR-15 derivatives, primarily the m16a2, m16a4 and m4m16 carbine, light machine guns (m240 and m249) and occasionally submachine guns (mostly the mp5), as well as various sniper rifles, against insurgent forces, armed with whatever they could get (usually AK-47 or AKM assault rifles, captured American weapons, dragunov sniper rifles, and improvised explosive devices, by far the most effective part of their arsenal). The Coalition forces, consisting of numerous nations, use their nationally adopted weapons, but their arsenal is similar in structure to American forces.

Overall, there wasn't a whole lot of change; an infantry squad consisted mostly of rifle-bearing soldiers (in world war 2, the bolt-action; in the Iraq War, the assault rifle) supplemented by troops with specialized weapons. However, unlike WW2, where both sides fought in mostly the same way, the Iraq War is fought by squads of American and Coalition troops against insurgents armed with basically whatever they can get.

If you mean used it in an act of warfare, as opposed to a test, the only country to do so has been the USA (Hiroshima and Nagasaki, 1945)

It was used to treat skin diseases and also as a fumigant to kill insects.

The ARA General Belgrano, a cruiser of the Argentine Navy, was sunk by the HMS Conqueror on May 2nd, 1982. It happened during the Falklands War. Two of the three torpedoes fired at the Belgrano struck the surface vessel, and she went down quickly with a large loss of life. A link can be found below for more information.

They were made by the United States during WW2.

The information given to the general public (me & you) leads to the conclusion; North Korea has nuclear arms, but struggles to maintain the weapons.

RUN LIKE HELL!!!

An atomic bomb works by initiating a chain reaction of nuclear fission, where atoms are split to release massive amounts of energy. This energy creates a powerful explosion capable of causing extensive destruction over a wide area. The bomb's design aims to achieve critical mass by bringing together enough fissile material to sustain this chain reaction and generate the explosion.

Around the end of 1944, due to Soviet spys. The US did not realize it had begun until the first Soviet test in 1949.

Nuclear Proliferation is the spread of nuclear weapons.

With conventional explosives to assemble a supercritical mass before it can begin a spontaneous chain reaction, melt and fizzle. Then a neutron source sprays the supercritical mass with a burst of neutrons at the optimal time to trigger a high efficiency chain reaction. The conventional explosives were detonated with electrical exploding wire detonators.

Currently 9 countries possess nuclear weapons;

The United States, United Kingdom, France, Russia, China, Israel, India, Pakistan and North Korea.

it disintegrates them in a radius or burns, deform, and give Leukemia to people if it is a plutonium

Hiroshima bomb: uranium

Nagasaki bomb: plutonium
