China could turn treacherous stretch into minefield to trap submarines

A recent study by Chinese military scientists proposes transforming the underwater terrain around the Paracel Islands into a strategic submarine kill zone by deploying AI-powered, long-endurance mines in sonar "acoustic shadow zones." These zones, characterized by complex underwater topography where sound waves scatter or disappear, provide natural concealment for mines, enabling them to evade detection and selectively target enemy submarines. The research, published in the journal Technical Acoustics by experts from the People’s Liberation Army Dalian Naval Academy and Harbin Engineering University, highlights how leveraging these underwater features could create a covert defensive network to trap adversary submarines, particularly those of the US, which regularly operates in the region to challenge Chinese dominance. The Paracel Islands, controlled by China since 1974 but claimed also by Taiwan and Vietnam, have become a heavily militarized hub with airfields, ports, radar, and garrisons supporting China’s strategic operations in the South China Sea. The proposed minefield system would rely on
