The U.S. Department of Defense has submitted a $3.1 billion funding request in its Fiscal Year 2026 budget to continue procurement of the F-15EX Eagle II fighter jet. The proposed funding was presented during a Pentagon briefing on June 26, 2025.
Developed by Boeing, the F-15EX is intended to replace aging F-15C/D aircraft and operate alongside fifth-generation platforms. The twin-engine jet incorporates an open mission systems architecture, upgraded avionics, and an increased payload capacity. Capable of carrying up to 12 air-to-air missiles, the aircraft is also under evaluation for compatibility with future hypersonic weapons.
Boeing reports that F-15EX production remains on schedule, with over 90 units currently in various stages of assembly. The company aims to reach a delivery rate of two aircraft per month by late 2026, supported by ongoing facility upgrades at its St. Louis plant.
The F-15EX is based on the F-15QA variant originally produced for Qatar but adapted to meet U.S. Air Force specifications. It features fly-by-wire controls, a redesigned cockpit, a digital backbone, and improved radar performance. The platform is expected to reduce maintenance time and streamline future system upgrades.
Earlier this year, former President Donald J. Trump stated that the F-15EX will assume the role of the A-10 Thunderbolt II in the Michigan Air National Guard. The planned transition was shared with personnel from the 127th Wing, reflecting broader force structure changes aimed at phasing out older airframes while retaining essential mission capabilities.
If approved, the requested funding would cover procurement of additional aircraft and related long-lead components. The exact number of jets to be acquired has not been specified. However, previous Air Force plans have indicated a total procurement target of up to 104 F-15EX fighters. Congress is expected to evaluate the proposal in upcoming budget deliberations, as the service weighs investment in both established and emerging air combat platforms.
