U.S. Army commissions new air defense battalion in Guam to counter missile threats

The U.S. Army formally stood up the 3rd Battalion, 43rd Air Defense Artillery Regiment in Guam at an activation ceremony on Oct. 16 held at Andersen Air Force Base. The new battalion assumes the air-defense responsibilities that had been carried out by Task Force Talon since 2013, a rotational force originally created to counter North Korean ballistic missiles. As China’s missile arsenal expands, the mission has broadened, and the battalion will operate Patriot, THAAD and Intermediate Fires Protection Capability systems to provide a layered defense against ballistic and cruise missiles, aircraft and drones.

Officials highlighted Guam’s strategic location as essential for regional operations, making robust air and missile defense critical. The transition signals a Pentagon commitment to permanent air-defense capabilities in the Indo-Pacific, supplementing existing THAAD launchers and U.S. Navy Aegis-equipped warships that currently protect the island on an as-needed basis.
