‘Eagle on steroids’ Arrives at Kadena Air Base, Japan

Two F-15EX Eagle II aircraft from the 85th Test and Evaluation Squadron, Eglin Air Force Base, Florida, arrived at Kadena Air Base on July 12 for integration and familiarization training with local units and joint partners.

This overseas deployment of the F-15EX, the U.S. Air Force’s (USAF) most advanced version of the Eagle and often referred to as the “Eagle on steroids,” offers a strategic preview of forward-based air power in the Indo-Pacific region.

The visit comes ahead of the planned permanent deployment of 36 F-15EX aircraft to Kadena in the spring of 2026.

“The arrival of the F-15EX at Kadena marks more than just a training opportunity; it is a glimpse into the future of air power in the Indo-Pacific,” said Brigadier General John Gallemore, 18th Wing commander. “By operating this next-generation platform in its future environment, we are laying the foundation for seamless integration, sustained readiness, and decisive advantage in a rapidly evolving security landscape.”

“We are using every test mission to gather critical data that will help refine the F-15EX and shape how we will operate and maintain it,” said First Lieutenant Kaylee O’Connor, officer in charge of the Red Aircraft Maintenance Unit, 96th Aircraft Maintenance Squadron. “When the platform arrives at Kadena, it will be seamlessly integrated with existing systems. This insight, from spares and maintenance to operational tempo, ensures the platform is mission-ready from day one.”

Equipped with advanced avionics, next-generation radar, electronic warfare systems, and expanded payload capacity, the F-15EX represents a leap forward in offensive and defensive capabilities. Its integration will strengthen Kadena’s ability to deter threats, enhance combat capability, and support the U.S.-Japan security alliance.

During its deployment in the region, the aircraft will also participate in exercise Resolute Force Pacific 2025.
