Chinese Subs are now attack proof from enemy submarines because of this new stealth technology

Chinese scientists have announced the creation of an innovative coating device that they claim can aid submarines in avoiding advanced enemy sonar by appearing like water. For years, submarines, including nuclear ones, have been involved in a game of hide-and-seek with the latest anti-submarine warfare capabilities. The improvement in technology has led to the development of cutting-edge tools that can assist navies in locating hostile submarines.

The newest Chinese technology seems to reverse this trend and escape detection. Active sonar is utilized to locate hostile submarines by transmitting a sound pulse from the submarine and determining the time it takes to arrive at the target and be reflected back. The tile-shaped device developed by Chinese researchers can allegedly examine an enemy's sonar frequency and create opposing sound waves. As a result, the sonar operator will be tricked into thinking that the submarine is water, as per the Hong Kong-based South China Morning Post. The Beijing Institute of Technology team claims that the low-frequency sounds produced by the tiles have an intensity of up to 147 decibels, which is louder than a rock concert and potent enough to block out some of the most effective active sonars used by the US military or its allies.
