About 50 percent of F-22 maintenance work is tied to low-observable coating repairs, a less-than-glamorous fact that helps explain why speculation about an “F-22 Super” is less about a new plane and more about sustaining a small, busy force for the long term. The slogan has been employed in the public domain as shorthand for a modernized Raptor, but the actual program has been in progress for years: a series of incremental software, sensor, and survivability improvements, as well as a sustainment program designed to keep the availability level from falling apart under the weight of stealth maintenance. Lacking a direct, in-production replacement to fill the gap, the upgrade conversation keeps coming back to what the F-22 can still do best and how to keep doing it.
Modernization has danced around revolutionary airframe design and concentrated on the systems that matter most: who sees whom first. Improvements to the APG-77 AESA radar, enhanced electronic protection, and a series of software upgrades have cumulatively improved the Raptor’s target detection, jamming resistance, and the fusion of its knowledge into something useful. The late 2000s to mid-2010s series of upgrades expanded the mission role, adding better mapping and targeting solutions that allowed for GPS-guided munitions and a radar-clean airframe design to become a stealthy first-night strike aircraft when called upon. Weapons integration followed the same theme: AIM-9X and AIM-120D extended the range but did not change the underlying mission to get in first, strike first, and get out.
Networking, long a problem area, has been upgraded in a series of tentative steps. The jet can receive Link 16 data, but the transmission of such data is still constrained in many ways in order to maintain signature. This is the same conflict that has come to define the engineering challenge for fifth-generation forces: how much to share in order to fight together without giving away one’s position, and it will ultimately define what “Super” means for the Raptor.
The current effort is clearly defined in terms of survivability against current sensing and missile threats. Budget reports address a “viability” package that includes signature management, cyber hardening, electronic warfare modernization, and the Infrared Defensive System, including improvements to missile launch detection. Simultaneously, the Air Force has announced a podded infrared search and track program, with two contracts for 15 pods already placed, with first deliveries expected in 2028. These, in combination, represent a Raptor that not only aims to be stealthy but also aims to passively detect that which the radar cannot, or that which the use of the radar may endanger.
The equation for range and survivability remains the same. Stealth is always at its best when it’s clean, but experience has shown that external tanks and accessories are required. The development of low-drag external tanks and pylons is intended to give the Raptor legs while maintaining the drag and signature effects under control, a philosophy that views “reach” as a survivability parameter rather than a nicety. Then there is the fleet management friction that makes sustainment a strategy.
A review by the Government Accountability Office warned that the Air Force had not shown how it plans to accomplish F-22 training or testing without the 32 Block 20 planes that are currently doing most of the work. The same report highlights that 90 percent of initial F-22 pilot training is accomplished on Block 20s, which makes the “retire the older jets” plan a readiness math problem: more training on combat-coded aircraft means more wear on the very aircraft needed for operational tasking. In this way, “F-22 Super” is a priority statement. Sensors, infrared warning, and networking are all well and good, but the hard battle is often the one that takes place behind the scenes diagnostics, paint, and the world of maintenance that ultimately determines how many Raptors are available when the mission list comes due.
