Do China’s New Islands allow it to militarily dominate the South China Sea?

Abstract: Since the start of China’s island-building efforts, there has been widespread concern that these islands would host long-range sensors and munitions and thereby facilitate Chinese military dominance in the South China Sea. This article explains that the military advantages that these islands provide are overstated. The interplay of geography and constraints on sensor coverage leaves China ill-positioned to detect ships and aircraft throughout the South China Sea, let alone to target them. While these technical constraints place hard limits on Chinese military capabilities, ameliorating them would likely face severe political constraints and major tradeoffs in force structure. Consequently, there are grounds for considerable skepticism of widely held concerns about the military implications of China’s island-building efforts. The military balance in the South China Sea has not been greatly altered and China’s anti-access capabilities, such as they are, have not been fully extended into the South China Sea.
