First F-15EX for Kadena Departs Boeing After Strike Delays; 36-Jet Deployment Begins

The first F-15EX fighter jet designated for permanent overseas basing departed Boeing's St. Louis facility on August 28 after months of delay from a factory strike, heading to Portland for final systems integration before deploying to Kadena Air Base in Japan in fiscal 2027. The aircraft is the lead of 36 F-15EXs scheduled for the 18th Wing, replacing legacy F-15C/Ds retired since 2022 and rotational squadrons that have been backfilling the Taiwan-proximate base.

The strike delay that pushed the first aircraft from spring 2026 to August 2026 cost PACAF five months of forward deployment and forced continued reliance on rotational squadrons with degraded capability. If Boeing's production line has stabilized post-strike, the next signal is whether the company can deliver at a rate that keeps Kadena's F-15EX fleet ahead of the rotation schedule—failure to do so extends the period when the base is dependent on borrowed squadrons and delays the integration training with Japan Air Self-Defense Force F-15s that the release emphasizes.

WHY IT MATTERS

Kadena's F-15EX arrival closes a capability gap that has forced PACAF to rotate aging fourth-gen fighters across the first island chain for four years.

The 18th Wing has been cycling F-16Cs, F-15s, F-22s, and F-35s through the base; the Colorado Air Guard's 120th Fighter Squadron brought 12 F-16Cs in January-June that pilots and maintainers said were operating at the limits of their 30-year-old airframes. The F-15EX—described as halfway between fourth- and fifth-generation—restores persistent, modern combat power within 400 miles of Taiwan without requiring rotational relief. Watch the FY27 delivery cadence: if Boeing hits the fiscal 2027 target for the first jet and sustains monthly deliveries, Kadena could reach IOC with 12-16 aircraft by mid-2027, which would signal INDOPACOM's confidence in the production line and its willingness to commit the aircraft to sustained forward presence rather than rotating inventory.

WHAT THIS DOESN’T TELL US

What is the actual delivery schedule for the remaining 35 F-15EXs to Kadena—monthly, quarterly, or clustered? The article says 'fiscal 2027' for the first arrival but does not specify the production cadence for the follow-on 35 aircraft, which determines when the 18th Wing reaches full operational c...
