The F 15EX Eagle II is the newest variant of the long-running F 15 line, built to give the US Air Force a fast, heavy, and highly adaptable fighter for modern missions. It keeps the raw speed and power of the original Eagle but adds digital systems, improved weapons capacity, and stronger survivability. Boeing produces the aircraft in the United States, where it serves as both an air superiority platform and a long-range strike fighter.
The jet carries advanced mission computers, a digital backbone, and the latest electronic warfare suite. These improvements help the F 15EX handle large sensor data loads and operate with other assets across the battlespace. The fighter uses two F110-GE-129 engines, which push it past Mach 2 and give strong acceleration at altitude. It also has a large payload capacity, allowing it to carry more air to air missiles than any other USAF fighter.
The aircraft uses the AN APG 82 AESA radar, which offers wide detection ranges and strong tracking against multiple targets. Paired with the Eagle Passive Active Warning and Survivability System, the jet gains improved protection in complex threat environments. The F 15EX supports a wide mix of weapons, including AIM 120 and AIM 9X missiles, JDAM, JASSM, and hypersonic systems in future updates.
The fighter is built for long service life. It includes open systems architecture for fast upgrades, stronger airframe materials, and higher flight hour limits. The USAF plans to use the F 15EX for homeland defense, air dominance, escort missions, and deep strike roles.
The F 15EX Eagle II price in the United States varies by configuration, training, and support packages. The flyaway cost is roughly 90 million dollars per aircraft, though full program expenses rise with sustainment and weapons integration.
