US Air Force Develops Six Pacific Backup Bases For Guam's Andersen AFB

The United States Air Force has been developing a network of alternative airbases across the Pacific to support operations in the event Andersen Air Force Base on Guam becomes unavailable during a conflict, according to recent reports. The strategic initiative reflects growing concern that Andersen—the most significant fully sovereign American air base in the Eastern Pacific—presents an obvious target that could be disabled, even if only temporarily.

Beyond the risk of direct attack, military planners acknowledge that existing bases in allied nations such as Japan and South Korea might not remain accessible if those countries opt for neutrality during regional hostilities. This vulnerability has prompted the development of backup facilities across the Western Pacific, some in locations that maintain unique political relationships with Washington.

Among the facilities being developed is Roman Tmetuchl International Airport in Palau, located roughly 820 miles from Andersen. Though an independent United Nations member state, Palau operates under a Compact of Free Association that grants the United States exclusive military operating rights throughout its territory. The arrangement, which took effect in 1994, positions Palau's facilities further south than Guam, complicating potential targeting scenarios. American F-35A fighters reportedly operated from the Palauan airport during 2023 exercises, while six C-17 transport aircraft used the facility the following year during Army Ranger airfield seizure drills.

The Air Force is also rehabilitating Peleliu Airfield, a previously abandoned facility on Palau's southern island, as part of its Agile Combat Employment doctrine designed to disperse operations during major conflicts. Additional development work is underway at Yap International Airport in the Federated States of Micronesia, positioned approximately 540 miles from Andersen.

The network expansion builds upon existing American facilities on Guam itself, including the civilian Antonio B. Won Pat International Airport, Claasson-Apra Regional Airfield, and Northwest Field, which is currently undergoing upgrades. Together, these installations form an increasingly robust infrastructure designed to maintain American air operations across the Pacific even if primary facilities face disruption.
