First F-15EX Fighter Jet for Okinawa's Kadena Base Completes Test Flights

The first F-15EX Eagle II fighter jet designated for deployment at Kadena Air Base in Okinawa has completed its initial test flights, bearing the tail code "ZZ" of the U.S. Air Force's 18th Wing. This marks a significant step in the modernization of U.S. air power in the Indo-Pacific region.

The aircraft, serial number 22-0022, underwent a primer test flight on August 4 and a full paint scheme test flight on August 15. This new fighter is part of a larger plan to replace the aging F-15C/D fleet at Kadena, which has operated the older models for over 45 years. The 18th Wing officially ended its F-15C flying mission in January 2025.

Originally, the first F-15EXs were anticipated to arrive at Kadena in spring 2026. However, U.S. Air Force Secretary Frank Kendall recently indicated that the initial deployment is now slated for 2027, with the full complement of 36 aircraft expected to be in place by 2028. This adjustment reflects the complexities of integrating new aircraft systems into existing operational bases.

Kadena Air Base will be the first U.S. base outside the mainland United States to host the F-15EX. The 67th Fighter Squadron will be the first unit to transition to the new aircraft, followed by the 44th Fighter Squadron. To prepare for this transition, the base has established a training squadron for the 67th Fighter Squadron and is providing maintenance personnel with training in Portland, Oregon.
