Forbes: U.S. Navy Submarines May Have Stealth Problems, But They’re Not Alone
Submarines rely on stealth to survive. An alarming problem with the U.S. Navy’s submarine stealth has come to the surface. A Sept. 26 whistleblower complaint accuses shipbuilder Huntington Ingalls of falsifying quality tests on the stealth coating of Virginia Class attack submarines, thus “knowingly and/or recklessly” putting “American lives at risk.”
This anechoic coating, which reduces the submarine’s sonar signature, is called Special Hull Treatment in U.S. Navy parlance. In layperson’s terms these coatings are usually rubber tiles glued on to the outside of the steel hull. The process of attaching them and final finish varies by country and is a very sensitive topic which, understandably, isn’t talked about. If the coating falls off, the submarine can be detected more easily.
