Nuclear Bombs

Nuclear weapons are a destructive force which gets thats force from nuclear reactions like fission or fusion. Nuclear bombs are stronger then any other weapon on Earth and one bomb can destroy a city like New York or Los Angelas. In the history of all conflicts only two Nuclear bombs have been droped during a war, both by the United States which were used on Japan during the end of World War two. Since these two bombings over 2,000 bombs have been detonated for testing purposes.

The countires that have detonated nuclear bombs for testing purposes are the United States, Soviet Unio, Britian, France, China India, Pakistan and North Korea. Other countries may have nuclear weopons but have never admitted that they do. It is believed that the US has the most nuclear weopons with 200 but Isreal has more modern ways of delivering them.

There two main types of nuclear weopons which are Nuclear Fission Bombs and Nuclear Fussion Bombs. Fission bombs include atomic bombs and A bombs, while Fission bombs include hydrogen bombs H bombs and thermonuclear bombs.Fission bombs are made up of a mass of fissile material which is essembled ino a supercritical mass. Fussion bombs can be a thousand times more powerful then fision bombs as fusions reactions release much more energy per unit of mass than fission does. A major challenge in all nuclear weopon designs is to ensure that the frction of the fuel is consumed before the weopon destroys itself.

Only 2 nuclear bombs have been dropped in the world. both have been dropped by the US against Japan in the end of WWII. The first was detonated on August 4th 1945, this bomb hit the city of Hiroshima and competely destroyed it. The second was 3 days later and it hit a smaller city,Nagasaki. It too was completely abolished.
