Decades after the end of World War II, the United States military is breathing new life into forgotten Pacific airbases. Driven by growing geopolitical tensions and an increasingly assertive China, Washington is quietly restoring strategic outposts that have been dormant for nearly 80 years.
The historical weight of these locations is profound. On August 6, 1945, the US Army Air Forces' B-29 bomber "Enola Gay" took off from Tinian—an island now part of the Commonwealth of the Northern Mariana Islands—carrying the first atomic bomb destined for Hiroshima. Once considered the busiest airbase globally with its four runways, the Tinian facility was abandoned in 1947, allowing the tropical jungle to reclaim the airfield on the island of roughly 3,500 residents.
However, in 2023, US government engineers initiated a major project to rehabilitate Tinian's 2,400-meter runways. Similar restoration efforts have also taken place on Peleliu, an island in the Republic of Palau.
Experts point to Beijing's regional expansion as the primary catalyst for these renovations. "China is the big concern in the region," explains Dan Pinkston, a former US Air Force officer and professor of international relations at Troy University in Seoul. "These works appear to be a reaction to China expanding its capacities in the region."
China has steadily fortified its presence in the contested South China Sea, developing military and civilian infrastructure on the Spratly (Nansha) and Paracel (Xisha) island groups. This militarization has sparked alarm among neighboring nations and US allies like Japan, South Korea, and the Philippines. Furthermore, Beijing's refusal to rule out the use of force to reclaim the self-governing island of Taiwan underscores its broad regional ambitions.
According to Pinkston, Chinese policymakers are determined to break through the "first and second island chains"—geostrategic defensive lines in the Pacific—to secure unrestricted ocean access. Taiwan sits on the first island chain, while the US territory of Guam anchors the second. By restoring these historical airfields, the US is preparing for potential future escalations.
The overarching US strategy involves creating alternative airfields to reduce reliance on primary hubs like Andersen Air Force Base in Guam and Kadena Air Base in Okinawa, Japan. The vulnerability of these concentrated bases has become a pressing concern.
The rehabilitation of Peleliu—originally built by Japan before being captured by US forces—illustrates this shift. Located on the second island chain north of Palau's main island, its 1,800-meter runway previously accommodated only small aircraft. Following upgrades by US engineers in 2024, a Lockheed KC-130 tanker aircraft with an 80-ton maximum takeoff weight successfully landed there in June.
"A decade ago, the US was deeply focused on configuring its Middle Eastern bases for armed conflict," notes Garren Mulloy, an international relations professor at Daito Bunka University. "Now, they seem to have realized how vulnerable their airbases and associated infrastructure are to a potential war in the Asia-Pacific." Mulloy adds that Washington was initially shocked by China's rapidly growing influence in the Indo-Pacific, a region the US had long considered its strategic backyard.
