During the majority of its service, the F-22 Raptor was not limited to speed, stealth, and agility as its greatest weakness but endurance. The low-observability shape and internal philosophy of fuel and weapons of the aircraft contributed to the characteristics of the fifth-generation air combats, yet left the jet with little distance capability and endurance to patrol without relying on vulnerable support units.
That historical limitation is now in public consideration, with a Lockheed Martin model exhibit at the 2026 AFA Warfare Symposium generating interest to put a Raptor with low-observable external fuel tanks and underwing sensor pods on display which are typical of an infrared search and track (IRST) fit. The visualized hardware resembles an effort to extend the reach and passive sense of the jet without dropping the signature practice that made the platform so challenging to overcome in the first place.
The most obvious one is the Low-Drag Tank and Pylon concept, where the external fuel is designed to act less like a bolt-on fix but more like an adjacency to the stealth geometry of the aircraft. The external tanks have a historical tradition of punishing a fighter in two ways: they decrease performance by causing additional drag and put the fighter at risk during radar detection. The depicted LDTP strategy implies the reverse: expansion of the range with the lowest signature penalties, as well as the fact that the tanks can be discarded as soon as the mission is not about transit but about penetration. In the case of a fleet with internal carriage as its design, that jettison option is significant; it returns to the base design condition when the airplane must fly with the tightest threat rings.
No less consequential is the sensor piece. A Raptor infrared search and track (IRST) pod provides the aircraft with a means of hunting without a radio emission sort of heat detecting targets instead of radar emissions. This alters the tactical geometry to high-tech electronic warfare and low-observable threats where the process of radiating renders an invitation to be tracked, geolocated and subject of counter-measures. It also facilitates a wider change of air combat: the necessity to create a shooting-quality picture and remain electromagnetically silent, and then distribute that picture throughout the force.
These additions come to build upon decades of gradual modernization that has already turned the jet into an increasingly versatile platform as a pure air-to-air-focused specialist. Prior upgrades enhanced the APG-77 AESA radar, increased electronic warfare survivability, and introduced synthetic aperture radar mapping, which enhanced quality of targets on the ground and strike capability. That is, the F-22 has to an ever greater extent been software, sensors and integration- not airframe reinvention.
A single sentence of the political moment of the time reflected where things had gone and the stress to maintain the capability alive: I believe the best fighter jet on the planet is the F-22, it will be a F-22 Super, a much modernized version of the F-22 fighter jet, U.S. President Donald Trump told a visit to Doha. Lockheed Martin vice-president OJ Sanchez packaged the push more as an issue of runway-management than an issue of engineering dead-end: “We are still asking, how can we make the airplane relevant?”
The question is beneath the whole “Raptor 2.0” discussion. The fleet cannot be grown rapidly with production still shut and export forbidden by the Obey Amendment; relevance has to be a capability density per tail. That is exactly what range extending tanks and passive IR sensing do, especially when an operation is over a long distance and tanker reliance and forward basing is a continuous challenge.
As the F-47 Next Generation Air Dominance fighter of Boeing proceeds to become the envisioned successor, the modernization of the Raptor is less of a stopgap, more of a bridge to be loaded with real cargo till sixth generation capability comes in substantial numbers in numbers.
