Kinetic Energy Penetrator Weapons

     Recently, the US military unveiled a massive kinetic energy weapon - a Trident II missile with a payload of tungsten rods designed to reenter the atmosphere at extremely high speeds, scattering kinetic buckshot everywhere and doing damage similar to the very largest conventional explosives. This is part of the "Prompt Global Strike" program, launched to find non-nuclear alternatives for strategic first strike capability. Because a nuclear-tipped Trident II and a KE penetrator Trident II both look the same from the outside, its hypothetical use may actually increase the chance of nuclear confrontation rather than decrease it, its intended purpose. Russian President Vladimir Putin mentioned this in a speech in May 2006, saying, "The launch of such a missile could... provoke a full-scale counterattack using strategic nuclear forces."

       KE penetrating weapons are frequently seen in science fiction, both in small and large form. Small arms frequently known as "needleguns" make appearances in cyberpunk fiction. Larger KE penetrators, such as space rocks dropped from orbit, feature in some sci-fi stories, and could truly be developed in the longer term future, despite treaties against the militarization of space. The ultimate form of KE penetrator would be a relativistic projectile, an object accelerated into a target at close to the speed of light. Fortunately, accelerating an object like this would require a tremendous amount of space and energy.

         As mentioned in the above, KE penetrating weapons are frequently seen in science fiction, So i am curious about this military product and want to know about this product. I found that tungsten plays an  important role in making KE penetrating weapons. If you want to know more details  about KE penetrating weapons and tungsten. please go to http://www.tungsten-alloy.com
