Final F-15 Eagle leaves Kadena Air Base as maintenance squadron deactivates

In early 2025, the United States Air Force deactivated the eighteenth Aircraft Maintenance Squadron (AMXS) at Kadena Air Base in Japan, marking a significant change in the operational capabilities of the base. With the withdrawal of the final F-15C Eagle, the Air Force plans to consolidate its equipment and maintenance operations. While the fleet of F-15Cs is being reduced, some aircraft may still transition to other units, including the Air National Guard. Additionally, parts from the decommissioned aircraft are being salvaged to support ongoing operations of remaining F-15s, preserving their capabilities for future missions. At the same time, the U.S. Air Force is preparing to enhance its air power presence in the Indo-Pacific region with the introduction of the next-generation Boeing F-15EX Eagle II. This modern aircraft is expected to arrive at Kadena Air Base beginning in spring 2026, between March and June, as the Air Force continues to seek ways to build a more advanced combat force. The Air Force’s investment in the F-15EX signifies a commitment to maintain operational readiness and adapt to evolving military requirements. The F-15EX Eagle II is distinguished by its numerous upgrades over previous models, including enhanced fly-by-wire flight controls, improved weapon stations, and an advanced electronic warfare suite. With a significantly larger payload capacity, the Eagle II can carry a greater array of modern weapons. Furthermore, its design necessitates only limited transitional training for pilots currently flying older F-15 variants, thus facilitating a seamless integration within existing squadrons. The U.S. Air Force continues to focus on operational efficiency and effectiveness, which is apparent in its approach to maintenance and modernization. Despite the reduction of F-15s at Kadena, the base remains an essential operational hub for the U.S. military in the Indo-Pacific. With historical significance, the F-15 has recorded over 100 air-to-air victories, primarily through the Israeli Air Force’s engagements. Notably, throughout its service history, no F-15 has been shot down in combat. The evolution of air power at Kadena reflects broader strategic imperatives of the U.S. military, emphasizing both a commitment to technological advancement and a responsive posture in an increasingly complex security environment in the region.
