China has begun implementing an unprecedented program of seabed mapping and underwater environmental monitoring, preparing for a potential confrontation with the US and its allies. According to a Reuters investigation, Beijing spends significant resources to eliminate the US Navy’s long-standing advantage in hydrographic knowledge.
Scale and objectives of the operation:
- Geography: PRC research vessels are actively operating in the Pacific, Indian, and even the Arctic oceans.
- Strategic Hubs: Special attention is paid to the strait between Taiwan and the Philippines (the Bashi Channel). Here, China has installed advanced sensors to track American submarines entering the South China Sea.
- Resource Base: A 5-year data analysis showed the involvement of 42 research ships operating in close coordination with China’s military institutes and universities.
- Expert Opinion: Ryan Martinson of the U.S. Naval War College calls these efforts “staggering,” noting that China is methodically undermining U.S. superiority in maritime domain awareness.
Analysis and Conclusion: China has shifted from coastal defense to a strategy of “power projection” in the world’s oceans. Mapping the seafloor and studying acoustic water parameters are critical preparations for using nuclear submarines. Knowledge of the “underwater landscape” allows Chinese submarines to move stealthily and set ambushes, neutralizing the technological superiority of American sonars. For the global community, this means the transformation of peaceful scientific research into a tool for military expansion, which will inevitably lead to the militarization of oceanography and new clashes in neutral waters.
