The hypothetical invasion requires China to shield nearby airspace, protect amphibious shipping, and prevent other powers from intervening. Carrier groups could guard the approaches, but their deployment would be a visible political and military commitment. Submarines are especially dangerous because several navies share compatible weapons, complicating attribution. The technological comparison credits US boats with longer development experience in submarine-specific sonar and naval architecture, while acknowledging improving Chinese designs. Taiwanese investment in drones and uncrewed systems adds another growing threat to prolonged resupply.
