Nuclear Weapons

No, Vietnam was LIMITED to conventional weapons only. A limited war.

The USS Greeneville (SSN-772) struck the Japanese fishing training vessel Ehime Maru about 9 miles off the south coast of Oahu, Hawaii. A link can be found below to a post that covers the incident.

short answer Hawaii

A U-Bomb was believed to be an Atomic (fission explosion) or Hydrogen (fusion explosion) Bomb with a Uranium Casing. The casing was supposedly made of U-238, residual uranium material leftover from processing that was non-fissionable (couldn't be made to explode like a U-235 bomb).

In a fission bomb, a U-235 (Uranium) or Plutonium (Uranium enriched through processing to increase the yield) nucleus is split with a neutron resulting in the release of nuclear energy as an explosion. In a fusion bomb, an isotope of hydrogen (either deuterium (H2) or tritium (H3)) is fused into helium by extreme temperature, which is generated by a fission explosion as the detonating device.

Since U-238 was essentially worthless, finding a use for it that would enhance either types of nuclear explosion would have been a major step, and it's thought that the U-Bomb was exactly that - a regular fission or fusion bomb with a casing made of U-238, which, though not able to be detonated like U-235, would explode in the high temperatures generated by a fission or fusion explosion, thereby enhancing the nuclear yield (intensity) of the explosion itself. For obvious security reasons, its existence was neither confirmed nor denied by the military.

Today, the design is part of some high-yield nuclear warheads, although the bombs would produce extreme amounts of radioactive fallout. The largest nuclear weapon ever detonated, the 50-megaton Soviet "Tsar Bomba", could theoretically have yielded 100 megatons or more because it used this design.

Type your answer here... weapon yard

I don't know every animal that would be able to survive, but Cockroaches are believed to be able to. The blast itself would kill everything around. The blast itself wouldn't destroy every living thing, but the radiation would do most of the work. Cockroaches can survive extreme heat and radiation.

1963

Various armor and shields.

- plate armor

- chainmail

- leather armor

- scale armor

- brigandine (cloth armor)

- several types of shields from wood or iron

The target was a protection from arrows and weapons in the fight man against man.

Just WW2, they have never since been used in war.

Contingency plans were drawn up for their use, and Westmoreland did discuss the matter with the Commander in Chief; it remained a contingency plan.

The first one used in combat was called Little Boy.

The most powerful bomb ever made was the tsar bomb.

the project for the atomic bomb was called...............................the Manhattan project

Above are not my words, I believe I can add some Clarity, or possibly confusion. I just graduated from college less than a year ago. Now I'm a Grad Student, and a really green one. I would also like to state that my grammar is horrible, also I will try to refrain from using words and concepts that only a physicist would understand.

The Military portion of this experimentation of these extremely complex reactions, was called "The Manhattan Project", however, there is much more to Nuclear physics than atomic bombs. The original name for this project, which started in 1939 was "Development of Substitute Materials". During World War 2 the British also had there own Nuclear program which was codenamed "Tube Alloys" Their project was absorbed into our own. The fact is we (The U.S.) are credited by far the most for the atomic bomb coming together and working, it was truly an effort by several nations, but only the U.S. refered to it as "The Manhattan Project" which as I hinted on earlier wasn't the original codename. The United States got pretty much all the credit, it's worth noting the fact that our interest in these materials, such as Uranium-238 or plutonium, in fact when the first atomic bomb was dropped, unless you were working in the nuclear program, you had never heard of plutonium, interesting fact, the british "Tube Alloys" program was called that because of plutonium. Something else that is not very well known is that the atomic bombs that were dropped on Hiroshima and Nagasaki, worked in 2 very different ways. Little Boy used a type of Nuclear reaction referred to as "Gun Type", Fat Man was an implosion-type Nuclear weapon. The implosion type was more practical. The first Atomic Bomb to ever be detonated was the implosion-type which occured during what was called "The Trinity Test". One of the main catalysts that pushed Atomic Bombs into political view was the "Einstein-Szilard" Letter, which was actually kind of a warning that it was theoretically possible to cause a chain reaction which would produce unheard of amounts of energy, but it also was a reccommendation for the U.S. to obtain as much Uranium ore as possible, this letter was sent around the Summer of 1939. Really this is more history of the development rather than the science of it. I really hope that this helps. For those of you who are intrigued by physics, lookup "Quantum Immortality" It's a thought experiment that is not hard to understand, but, it's implications are fascinating. I added all of this completely from my knowledge of the History of physics, if you find something I didn't quite get right, please feel free to add to this or edit this, just make sure that it is indeed incorrect before changing anything.

There probably would have been no cold war, but there probably would have been WW3, probably starting in early to mid 1950s.

No. It can DAMAGE a bulding- cracking glass or plaster- but the air transferred energy is just not that high. Can scare the pants off of you if you are not expecting it!

No. No nuclear weapons have ever been used in an act of war besides the two dropped on Japan during the Second World War. The United States and Russia both produced enormous amounts of nuclear weapons during the Cold War, though none were used.

It certainly can. peopls say that it can destroy a whole country

A nuclear fallout is when some country drops a nuclear bomb that is very deadly and usually spreads through the air. I doubt there would be one in the furture but if there is grab a gas mask and hide in a basement or something.

i heard that china and America have nuclear bombs so buy that gas mask and get sum supplies in ur basement

Gasmasks do nothing likewise fallout is radioactive dust detectable by a geiger counter meter, A booklet issued in 1960-1980s Britain. Protect and Survive. stated before an attack paint windows white (it reflects heat) stay indoors in a single room or cupboard(fallout room) (away from outside walls if possible), Stock up on supplies, Prop thick wooden doors or simalar against an inside wall away from windows at a 45degree angle and fix to wall or floor, Stay in shelter for 48 hours and 2 weeks in fallout room, remove burnable materials e.g. paper or thin wood

In the 60's we called them "bomb shelters."

The United States was the first country to build a nuclear submarine, and that boat was named the USS Nautilus.

First of all there are heavy and unstable metals in the nuclear bomb. These are mainly uranium, polonium, plutonium etc.These are then bombarded with hydrogen atoms (tritium and deuterium) with the help of atom guns (or nuclear guns). This displaces the nucleus of the metals and it starts to divide. The more it divides, more energy is formed (as the properties of the atom changes).

2->4->8->16->32->64->128->256->512->1024 ....... infinity (until the radiation gets over)

Fear that Nazi Germany would make one first and win WW2 using it. It was not until after the end of the war that it was discovered that the German nuclear program was only a very low priority program directed mostly at reactor development.
