China's Undersea Mapping: A New Threat

0:00On March 24, China is leading a massive undersea mapping and monitoring campaign across the Pacific, Indian, and Arctic oceans. Naval experts warn this effort gathers vital data on ocean floors, temperatures, and currents perfect for submarine warfare against the United States and its allies. Research ships from state universities have criss-crossed key areas for years. Take the Dong Fang Hung 3, for example. This vessel from Ocean University of China sailed repeatedly near Taiwan and Guam in 2024 and 2025, while also checking. Sensors off Japan and scouting routes to the Malaka Strait. It's part of a larger operation with dozens of similar ships deploying hundreds of sensors. Experts from the US Navy and beyond say the data sharpens China's ability to hide subs, track rivals, and optimize sonar. Former submarine leaders note, it prepares the battle space, closing the knowledge gap the US once held. Officials highlight risks to navigation and concealment in contested waters.

The transparent ocean project, backed by millions, rings choke points with buoys and arrays for real-time monitoring, fueled by civil military fusion, policies. This buildup underscores China's push into far seas, blending science with defense to challenge undersea dominance and secure vital trade paths.
