U.S. Air Force to Modernize F-22 Raptors with Advanced Tech to Extend Lifespan and Combat Edge

The U.S. Air Force is moving forward with a comprehensive plan to upgrade its fleet of F-22 Raptor stealth fighters, aiming to keep the aircraft combat-ready and technologically superior well into the future. As part of the Pentagon's 2026 fiscal year budget proposal, $90.34 million has been allocated for a series of major enhancements designed to modernize the F-22’s capabilities in line with current and emerging threats.

The F-22 Raptor, known for its unmatched air dominance, stealth features, and supermaneuverability, remains one of the most advanced fighter aircraft in the world. However, with evolving warfare technology and new generation threats, the Air Force intends to equip the Raptor with next-level systems that will extend its relevance on the battlefield.

One of the key additions is the Infrared Defensive System (IRDS), which will improve the aircraft’s survivability by allowing it to detect and respond to heat-seeking missile threats. This is particularly important in environments where stealth aircraft may still face detection from infrared sensors.

The upgrade plan also includes improvements to the Low Observable (LO) features of the F-22, which are responsible for its radar-evading stealth profile. This means refinements to the aircraft’s coating, shape, and materials to stay ahead of radar advancements.

A major technological leap will come with the enhancement of the radar system, which will now include a dynamic Synthetic Aperture Radar (SAR) capability. SAR allows the aircraft to generate high-resolution ground imagery from the air, even through clouds or darkness, enabling it to identify ground targets more precisely.

In terms of offensive and situational awareness capabilities, the Air Force plans to integrate an Infrared Search and Track (IRST) system, known as TacIRST. This passive sensor enables the F-22 to silently detect and track enemy aircraft by their heat signatures, without using radar—giving it a decisive advantage in stealth engagements.

Pilots will also benefit from a redesigned Pilot Vehicle Interface (PVI), which includes updated cockpit displays, control systems, and human-machine interaction tools. To complement this, the Air Force has partnered with LIFT Airborne Technologies to develop the Next Generation Fixed Wing Helmet (NGFWH)—a state-of-the-art helmet that enhances situational awareness and supports integration with future systems.

Another significant advancement is the development of stealth-compatible external fuel tanks. These are designed to extend the aircraft’s range without compromising its radar signature, allowing the F-22 to operate deeper into contested airspace.

Currently, the U.S. Air Force operates 185 F-22 Raptors, but only 143 of these are combat-coded and ready for deployment. The rest are used for training, testing, or are undergoing maintenance. The modernization project is essential not only to maintain the operational readiness of the combat fleet but also to ensure that the F-22 remains a formidable air superiority platform in the years to come.

Although the F-22 program was officially closed for new production in 2011, the U.S. Air Force is determined to maximize the performance and relevance of its existing Raptors as new-generation aircraft like the NGAD (Next Generation Air Dominance) fighter continue development.

This modernization reflects a broader U.S. defense strategy that emphasizes upgrading existing platforms with cutting-edge technology to meet near-peer threats—particularly in an era of rapid advancements by adversaries like China and Russia. The upgraded F-22 will continue to play a crucial role in U.S. air superiority missions, deterrence, and global power projection.
