China’s recently emerging yet mysterious three-engine stealthy 6th-gen J-36 may launch from an aircraft carrier, should PLA scientists succeed with current efforts to integrate the large new platform onto its carriers.
I is widely known that the PLA’s J-35 is carrier-capable, as it represents the next phase of what was the J-31, prototypes of a stealthy, 5th-gen carrier-launched fighter under development for many years.
The emerging J-36, however, is a much larger three engine stealth fighter-bomber hybrid, likely far more difficult to operate from a carrier.
“Chinese media estimate the J-36 to be about 75 feet long and weigh between 99,200 and 119,000 pounds, significantly larger and heavier than fifth-generation jets like the J-20, which weighs around 75,000 to 82,000 pounds,” an essay in Interesting Engineering states.
Unlike the J-35 which has vertical tails for increased stabilization advantageous for turbulent carrier landings, the J-36 is an entirely horizontal blended wing-body configuration. While this might improve its stealth properties, provided the heat signature emerging from three engines can be managed, yet the absence of vertical fins and tails for maneuvering might make navigating high-winds and turbulent seas more difficult.
Nonetheless, the PLA is specifically making technological efforts to address this challenge, with the ostensible aim of operating the flying wing J-36 from a carrier. An essay in the South China Morning Post, cited in Interesting Engineering, reports that Chinese scientists are currently exploring new “direct force control systems” designed to enable control surfaces to overcome aerodynamic challenges associated with landing the J-36 on a carrier.
A carrier-capable stealthy, 6th-generation fighter-bomber hybrid such as the emerging J-36 would likely present new threats to the US and its allies as it could bring bomber-like stealth properties and payload capacity to a forward-operating maritime combat environment. Such a contingency could improve stealth attack ranges, extend dwell time and mission scope while integrating the high-speeds, maneuverability and air attack capabilities of a stealth fighter jet.
After first appearing on social media in December, 2024, an occasion which developed no shortage of speculation and ad-hoc analysis, the People’s Liberation Army Air Force J-36 was subsequently captured a second time, adding a window of visibility of several different, previously unseen angles. The aircraft may be breaking some new ground and introducing as of yet unprecedented stealth configurations, as the fuselage resembles elements of both a stealth bomber and stealth fighter jet. It could almost be seen as a kind of deliberate hybrid blending of the horizontal blended wing-body design fundamental to high altitude bombers and a maneuverable, high-speed lower altitude fighter jet. The shape of the aircraft appears to incorporate elements of both, something which raises questions as to whether it represents a technical breakthrough or is instead an ineffective, overly ambitious effort to do too many things with a single aircraft.
Landing Drone on Carrier
It makes sense that a larger, heavier and less maneuverable aircraft might have difficulty landing on a carrier, particularly one without fins or tails added for vectoring
Fighter-Bomber combination
Could it be possible to engineer a “tactical stealth bomber” able to both carry large amounts of ordnance and perform fighter-jet-like air combat maneuvers? If so, it would suggest the PLA has made new aerodynamic breakthroughs, yet the appearance of these potential attributes may be an overly-ambitious effort to blend too many unique characteristics into a single aircraft. The diamond-shaped wing, however, does not appear to incorporate any tails, fins or vertical structures, a clear effort to reduce the aircraft’s radar signature. Similar to industry renderings of US Air Force 6th-generation designs, the J-36 indicates that both US and Chinese engineers may have found ways to maneuver and vector without needing tails and vertical structures typically used to manage air-flow and enable high-speed maneuvers. Available views of the fuselage show a large, smooth flat tactical bomber with fighter-jet like inlets beneath the wings. High altitude ultra-stealth bombers typically blend the inlet in the structure of the fuselage above the wing in a smooth-rounded configuration. The absence of hard edges or protruding structures lowers the ability of “electromagnetic pings” to bounce off a structure and deliver an accurate rendering or radar return signal. Such is the case with the US B-2 and B-21, as they are built to appear like a “bird” to enemy radar.
The J-36, however, combines this kind of design with fighter-jet like attributes such as an angled, pointy nose for optimal speed and rectangle-like inlets beneath the wings similar to what is seen on the F-35 and F-22. While this might enhance fighter jet-like capabilities, it can decrease stealth effectiveness to a certain extent by increasing the radar signature. Stealth properties are of course also heavily influenced by heat signature, and its not immediately clear what kind of thermal management methods might be incorporated into the J-36.
Perhaps the most significant element of the J-36 pertains to its apparent “3-engine” structure, something which could reduce stealth but potentially introduce new dimensions of speed, power and aerial agility. The third engine might represent an effort to bring F-22-like aerial maneuverability to a larger, heavier, bomber-like platform. While a 3rd engine might increase speed and offer vectoring possibilities for a larger bomber-esque platform, it likely challenges efforts to reduce heat emissions and could decrease stealth. Three engines would increase speed, however, and that is something which is a survivability enhancing attribute as well.
J-36 Concepts of Operation
All of these variables raise questions about the intended Concepts of Operation for the fighter, because the J-36 could connect fighter-jet-like speed with bomber-like payload carriage. Available images of the J-36 do show a large internal weapons bay, something which raises the possibility of a lower, altitude tactical bomber able to fly with large, B-2-like ordnance payload. This allows an aircraft to operate with longer dwell-time and the ability to drop a larger number of weapons on target in a single mission. The larger body also means the aircraft could possibly fly longer missions by virtue of being able to carry more fuel than a standard fighter.
Does the J-36 strike an optimal blend of attributes capable of introducing unprecedented air-attack possibilities? This certainly seems possible, yet there are still too many unknowns. For example, what kinds of sensing, mission systems or fire-control technologies does the J-36 have? Can it operate with F-35-like long-range high-fidelity sensors such that it can destroy enemy targets at standoff distances where it is not detected? What kinds of computing, fire-control and weapons interfaces does the aircraft incorporate? Does it really achieve a new degree of stealth multi-role versatility?
The PLA itself might not yet have the answers to all of this, as the aircraft may only be in a demonstrator, experimental phase not yet ready for production. There is evidence to support this, according to an interesting essay from the Aviationist which pointed out a forward data probe on the aircraft, something typically done during initial testing and assessment phases of new platforms for the purpose of collecting data for further analysis.
All of this raises the question of whether there is a strategic and tactical advantage to building a fighter-bomber hybrid or what could be called a “tactical bomber.” Unlike a higher altitude, a fully horizontal bomber such as China’s H-20 could be a faster, lower-altitude bomber that could potentially carry much ordnance closer to target areas while preserving an impactful measure of stealth.
As opposed to a fighter jet, a tactical bomber brings the possibility of attacking a greater number of targets, given that it can operate with more weapons. Also, as a tactical fighter, the new hybrid might be quick and maneuverable to a point where it could elude or at least challenge enemy air defenses. A pure stealth fighter, by contrast, can drop some JDAMs and large laser-guided GBUs, yet its internal weapons bay is much smaller than this tactical bomber would be, and loading up in beast mode can compromise the effectiveness of stealth.
Ultimately, it seems the actual margin of difference would pertain to performance parameters less visible to the observer, such as mission systems, sensing, computing, fire control, and weapons delivery.
Should this new tactical bomber operate with anything like a B-21, with the ability to perform command and control in the sky as a “sensor node” or an F-35, and the ability to maneuver against and attack air defenses, the new aircraft could indeed present an unprecedented threat.
