UN F-15EX Eagle II has touched down at Kadena Air Base. The newest variant of Boeing's legendary air superiority fighter landed on Okinawa's most strategically important airfield on June 29, returning to the Pacific's frontline base a year after the type's inaugural visit — and giving a quiet preview of what permanent deployment might look like. It is not staying. Not yet. But the visit matters.

The Gap at Kadena

Kadena has had a fighter problem since 2022. The base's F-15C/D Eagles — some of the oldest combat jets in the USAF inventory — began phasing out in late 2022 without a permanent replacement. Since then, the Air Force has relied on rotating deployments of F-22 Raptors and F-35A Lightning IIs to fill the gap. It works, but rotational forces lack the institutional knowledge that comes from a permanently stationed squadron. The F-15EX was supposed to fix that. Boeing's upgraded Eagle carries a modern AN/APG-82(V)1 AESA radar, fly-by-wire controls, and the ability to haul twelve AIM-120 AMRAAMs simultaneously — more air-to-air missiles than any other Western fighter. But the 2025 Boeing machinists' strike delayed production, pushing the permanent Kadena deployment timeline to the right.

Why Kadena Matters

Okinawa sits roughly 370 miles from Taiwan and 400 miles from the Chinese mainland. Kadena is the largest U.S. air base in the Pacific — a sprawling complex with two 12,000-foot runways, hardened aircraft shelters, and decades of infrastructure built for exactly the kind of high-end fight that Pentagon planners now consider plausible. A permanently stationed F-15EX squadron at Kadena would give the Indo-Pacific command a fighter that combines raw payload capacity with the latest sensors — a complement to the stealthy but weapons-limited F-35A. The Eagle II is not invisible, but it can carry enough ordnance to make that a secondary concern.

Cosa succederà dopo?

The first permanently based Eagle IIs are expected at Kadena sometime in 2027, Air Force Secretary Troy Meink told the Senate in May. Production recovery from the Boeing strike is underway, and the service continues to accept deliveries at Eglin AFB, Florida. The current visit is officially a short-term training and familiarisation deployment — letting crews and maintainers experience the Kadena environment with the new jet. But familiarisation deployments have a way of becoming permanent. The F-22's rotational presence at Kadena, intended as a stopgap, lasted years. The F-15EX's visit may be a single data point, but it draws a clear line from St. Louis to Okinawa — and from the 20th century's most successful air superiority fighter to its 21st-century successor.
