Record of Decision for the Enhanced Integrated Air and Missile Defense System on Guam Environmental Impact Statement

25-NEWS-0009
Sept. 8, 2025

The Missile Defense Agency (MDA), as the lead agency, and the U.S. Army, as a cooperating agency, jointly issued a Record of Decision (ROD) to implement the construction, deployment, and operations and maintenance of the Enhanced Integrated Air and Missile Defense (EIAMD) system on Guam. The action will enable MDA and the U.S. Army to meet their congressional mandate for a persistent 360-degree layered Integrated Air and Missile Defense capability on Guam to address the rapid evolution of missile threats from regional adversaries. In addition to the U.S. Army, the U.S. Air Force, U.S. Navy, and Federal Aviation Administration (FAA) participated as cooperating agencies in the development of an Environmental Impact Statement (EIS) due to their jurisdiction or special expertise as it pertains to certain components of the action or for potentially affected operations and resources.

The MDA and the U.S. Army selected the Proposed Action after considering the need for the system, potential environmental impacts, and comments received from elected officials, government agencies, nongovernmental organizations, and the public. Mitigation measures that avoid, minimize, or mitigate potential environmental impacts will be employed.

Record of Decision Availability

The MDA and the U.S. Army encourage the public to view the ROD, which is available on the MDA public website for download or in print at the University of Guam Robert F. Kennedy and the Nieves M. Flores memorial libraries. If you have questions or would like additional information, please visit www.mda.mil/system/eiamd or email info@EIAMD-EIS.com.
