According to Timothy Heath, the “tactical significance [of the deployment] increases when deployed in combination with other anti-access, area denial (A2/AD) weapons.”
“The most direct tactical effect in peacetime is to threaten the safety of U.S. surveillance and reconnaissance aircraft that may pass by the islands, such as the U.S. Navy’s P-3 or P-8 patrol planes.”
