In an increasingly competitive strategic environment, backed by an additional $3.1 billion investment, Boeing has intensified production of the F-15EX Eagle II fighter-bombers, intended to strengthen the capabilities of the United States Air Force. The goal is to reach a delivery rate of two aircraft per month by the end of 2026, ensuring a steady flow of the latest variant of the renowned Eagle.
This decision is not the result of an isolated push, but rather part of a comprehensive strategy to reinforce the U.S. posture in the Indo-Pacific, a region where tensions with China have escalated. Beijing continues to expand its fleet of J-20 stealth fighters, consolidating its military presence around Taiwan and the East China Sea. Added to this are Russia’s advances in air defense systems, stealth platforms, and hypersonic threats — factors that make the acquisition of the F-15EX a critical priority for maintaining air superiority.
So far, the U.S. Air Force has received 8 F-15EX aircraft from lots 1A and 1B, delivered last year. These planes are intended to replace the veteran F-15C Eagle, whose operational obsolescence demands urgent renewal. The contract awarded to Boeing in 2020 is part of a broader defense package valued at $150 billion, covering priority programs through 2029. Initially, the acquisition of up to 144 units was considered, although that number could be adjusted due to budget constraints and the parallel focus on the F-35 Lightning II program.
Boeing has attributed the increase in production speed to significant improvements in manufacturing efficiency and quality control, under the “Cost of Rework and Repeat Scrap Reduction” (CoRRs) initiative. This system implements a “daily quality hour,” where teams solve manufacturing problems in real time, minimizing delays and defects. Added to this is the aforementioned $3.1 billion injection, announced in April of this year, aimed at further accelerating the program.
As for the current status of the production lots, it has been reported that the F-15EX lots are progressing through different assembly phases at Boeing’s St. Louis plant. Regarding the second lot, the first aircraft is undergoing flight tests. The third lot is advancing with the assembly of the forward fuselage. And finally, the fourth lot is already in active production.
Lastly, in a scenario where electronic survivability and precision reach are decisive, the F-15EX emerges as a vital complement — not a replacement — to fifth-generation stealth fighters, ensuring that the USAF maintains its qualitative edge in high-risk theaters of operations.
