War on the Rocks – Sensing vulnerability, the United States and its regional allies and partners are ramping up procurement of air and missile defense assets, though progress is likely to be constrained by competing spending priorities and already overstretched defense industrial bases. These constraints underscore the need for complementary approaches that can deliver near-term gains without relying solely on expanded procurement. Networking missile sensors and interceptors across the United States and its Indo-Pacific allies and partners is one such approach. Coalition air and missile defense can generate operational efficiencies in sensing and interception that have the potential to shrink Chinese air and missile advantages. While compelling in theory, is it feasible in practice? Can the United States and its allies and partners navigate the challenging geography and politics of the Indo-Pacific to counter Chinese air and missile advantages through coordinated air and missile defense?
