Forget the F-35: At 87,000,000,000 Operations Per Second, the Mach 2.5 US Air Force F-15EX Eagle II Is a Real Flying Supercomputer

The U.S. Air Force’s F-15EX Eagle II is being pitched as a “flying supercomputer,” built on the long-running F-15 platform but updated for modern, highly contested missions. The first F-15EX aircraft were delivered in 2021 and entered operational service in July 2024. As an all-weather, multi-role strike fighter, it is designed to complement stealth assets like the F-22 and F-35 by pairing with them in combat to help neutralize air defenses. Central to the pitch is its Advanced Display Core Processor II (ADCP II), capable of 87 billion operations per second. It also includes the EPAWSS electronic warfare suite and an Open Mission Systems architecture.
