What occurs when a small fleet having elite kinematics encounters a competitor capable of iterating rapidly and deploying variants at the field and continuing to develop? That is the kind of engineering tension that is looming over any F-22 Raptor versus J-35A discussion, with the airframe being a factor but the bigger battle is in sensors, survivabilities, and scale of manufacturing.
The F-22 is a standard due to its design based on a ruthless priority win the first exchange. The jet is still characterized by speed, low observability and a propulsion package that was designed to sustain performance. Yet the Raptor is also a small-force asset by modern standards, having 185 aircraft in inventory and 143 combat-coded planes in inventory, which determine all of the readiness as well as the frequency of upgrades across the fleet.
That upgrade pipeline has turned into a story. The 2026 budget request of the U.S. Air Force is a newly proposed “viability” program, which includes signature management, cockpit interface upgrades, radar and electronic warfare upgrades, cybersecurity, and a modernized missile-warning capability with the Infrared Defensive System (IRDS) in the middle. The language used in the budget is rather broad, detailing a combination of both hardware and software work as being associated to, but not necessarily limited to, low observable maintenance and pilot-vehicle interface, a reminder that in mature stealth systems it is refinements that are often made incrementally and tightly coupled, as opposed to a single headline upgrade.
One such technological trend, specifically, IRDS, indicates a future in which passive sensing and missile-launch detection are not side-show technologies but fundamental survival technologies. The Raptors also are to be equipped with podded infrared search-and-track sensors and already the first production orders are made towards 30 pods, and the initial delivery is planned in the second quarter of Fiscal Year 2028. In engineering terms, it is a matter of restoring margin: expanding the awareness of the Raptor in the worlds where radar emissions and electronic attack have made everything complicated, as well as providing pilots with new opportunities to create quality tracks of engagement, but not advertise their presence.
Opponitely, the J-35A of China can be viewed as a relative of a larger force-design solution, but not a single challenger. It is a complement to the heavier J-20, designed to engage the medium-weight multi-role avenue, air superiority, precision strike and regional coverage with a design that focuses on internal carriage, diverterless supersonic inlets and shaping to suppress radar returns. This is as the aircraft continues to lag Western aircraft in sensor fusion and networking, but what is more relevant is the capability of China to ship out versions that can be used in various services and missions as the production scales up.
The naval aspect focuses the analogy. The carrier-based J-35 has been attached to the work of the Type 003 Fujian the first catapult-fitted carrier of China and the embarked air wing of about 48 aircraft is discussed. That is important as it imposes on stealth aviation the carrier deck-cycle fact: launch weight, reinforced landing gear, recovery loads, and the cast of airborne early warning and deck handling. It also repositions stealth fighter as a problem in which an airbase is a center of operations to a problem of sustained maritime operations: the generation of sorties and the networked sensors can be decisive even more than the actual aircraft performance.
At that, the headline question, whether the J-35A is a Raptor-killer, puts too much in one headline. The F-22 has been always an amalgamation of low observability, thrust, and pilot interface that is air dominance focused. The pressure point of J-35A is its timing and its ecosystem, which is the newer assumptions of computing, a growing stealth inventory, and a program architecture capable of supplying both carrier-based and land-based aviation. The reality of engineering is that capability has now become something that is negotiated on the continuous and on the one hand, by means of upgrade cycles and, on the other, by means of growing production capacity.
