Zumwalt-class destroyer has a huge size and large tonnage, its manufacturing cost is also very expensive. The first DDG-1000 cost is exceeded$3 billion 500 million, which is the most expensive destroyers of the U.S. Navy in the history. The length of Zumwalt-class destroyer is 185 meters, its displacement is about 15000 tons. The angle type structure and a new type of stealth design makes its probability that detected by radar is less than 10% during navigating, so it is a stealth destroyer. Zumwalt-class destroyer carries a kind of advanced gun system which ranges is more than 100 kilometers, and three times of the active destroyer gun range.

 

Although the Zumwalt-class destroyer has so proud military strength, but this scale will also increase the sinking risk of being hit by the rough sea waves on the destroyer’s tail. Therefore, increasing counterweights to Zumwalt-class destroyer is an important measure that can ensure to against rough sea waves in navigating. Tungsten alloy has the characteristics of high density, non-toxic environmental protection, as the counterweights to Zumwalt-class destroyer can not only strengthen their ability to resist rough sea waves, but also do no harms to the the marine ecological environment. So tungsten alloy is the ideal counterweights material for Zumwalt-class destroyer.
