Guam Flight Test

The Missile Defense Agency (MDA), in cooperation with the United States (U.S.) Navy, U.S. Air Force, U.S. Army, and U.S. Coast Guard (Cooperating Agencies), has prepared an Environmental Assessment (EA)/Overseas Environmental Assessment (OEA) to evaluate the potential environmental impacts from proposed missile defense flight tests or target tracking exercises conducted from Andersen Air Force Base on Guam or at sea from a Navy ship in the western Pacific Ocean (Proposed Action). The Proposed Action includes conducting up to two flight tests or tracking exercises per year over a 10‐year period. The purpose of the Proposed Action is to validate the interoperability of multiple sensors and interceptor systems that could become part of a missile defense system developed to protect Guam.
