The US Air Force is considering upgrading 35 early-model F-22 Block 20 Raptors, previously slated for retirement, transforming them into fully combat-capable stealth fighters. The move aims to strengthen America’s air dominance until the next-generation NGAD (Next Generation Air Dominance) platform is ready.
Lockheed Martin’s advanced design division, Skunk Works, has confirmed ongoing discussions with the Air Force regarding the modernization plan. Originally built as training aircraft, the Block 20 Raptors lack the advanced systems found in newer variants. The proposed upgrade would enhance the fleet’s readiness and extend operational capability through the late 2020s.
The modernization package under review includes integration of updated sensors, infrared search-and-track systems, enhanced electronic warfare suites, and open-mission architecture for faster software upgrades. The plan also explores manned-unmanned teaming links that would allow the F-22s to operate collaboratively with future autonomous aircraft under the Air Force’s Collaborative Combat Aircraft (CCA) program.
“Upgrading these airframes offers the Air Force a cost-effective way to sustain stealth capacity while advancing toward the NGAD era,” said a Lockheed Martin spokesperson. “The F-22 remains a cornerstone of US air superiority, and these improvements ensure it stays ahead of emerging threats.”
If approved, the conversion program could deliver a meaningful boost to the fighter fleet at a time when the Air Force seeks to balance modernization with force availability. The decision would also provide valuable testing opportunities for integrating CCA technologies and digital upgrades across the stealth fleet.
By revitalizing older F-22s, the Air Force could preserve a decisive edge in air combat while transitioning to sixth-generation capabilities, reinforcing both deterrence and operational flexibility in contested environments.
