The US Air Force is quietly phasing out 21 F-15E Strike Eagles, specifically those powered by the Pratt & Whitney F100-PW-220 engine. These jets generate roughly 23,770 lb of thrust, meaningfully less than the 29,000 lb produced by newer models.
Maintenance costs on -220-powered airframes have climbed as components age and suppliers thin out. This is a significant pressure point when older jets demand disproportionately more maintenance hours per flight hour.
The retirement of these 21 airframes represents fewer than 10% of approximately 218 F-15Es in the inventory, with newer -229-powered Strike Eagles expected to remain in frontline service into the 2030s.
Their replacement is the Boeing F-15EX Eagle II, procured in FY2026 as 21 aircraft at roughly $147 million per unit, for a total of $3.1 billion.
The EX features an open-mission systems architecture, 13 weapons stations, digital fly-by-wire controls, and conformal fuel tanks that extend combat radius by approximately 200 nautical miles.
Over time, the F-15EX will absorb the Strike Eagle's deep-strike role, while the F-35A takes on stealth-penetration missions. This marks a significant shift in the Air Force's modernization strategy.
The F-15C/D service ends after 45 years, with no fighter jet in history retiring with a cleaner combat record than this one. The last active-duty F-15C completed its final flight at Kadena Air Base, Japan on January 24, 2025.
A Congressional mandate extended the service life of structurally sound survivors, unofficially called 'Platinum Eagles', at Fresno ANG Base through 2030 for homeland defense missions.
This retirement highlights the need for ongoing investment in fighter jet technology and modernization to maintain a competitive edge in air-to-air combat.
