China’s J-36 stealth fighter prototype, touted as a sixth-generation aircraft, has emerged into public view for a second time during test flights.

Images circulating online have reignited discussions about its design and capabilities. The aircraft’s tailless configuration has drawn attention, sparking debate about its potential impact on next-generation aircraft designs.

The newly surfaced images and video of the J-36 provide a clearer view of its key design features.

One notable image captures the aircraft from the side, highlighting its streamlined canopy, which aligns with the forward fuselage, and its dorsal air intake, which seems to employ a diverterless supersonic inlet (DSI) design. This perspective also reinforces speculation that the jet may feature side-by-side seating due to its broad nose section.

Another striking image shows the J-36 in triple reheat during terminal operations, either taking off or executing a go-around. This showcases its rare three-engine layout and distinctive twin split ruddervators positioned on each wing in an unusual configuration for tactical fighter aircraft.

Beijing has maintained silence on the J-36’s development. The aircraft was first unveiled on December 26, 2024, through online photographs and videos of a test flight near Chengdu, Sichuan.

The aircraft’s trijet design, featuring a blended double delta wing structure, was immediately noted. These aerodynamic features suggest a focus on stealth, range, and speed, critical attributes in contemporary air combat.

The second sighting in March 2025 provided further glimpses of its advanced capabilities, fueling discussions about its potential to challenge U.S. air superiority. The development of the J-36 stems from China’s broader pursuit of sixth-generation fighter technology.

In 2019, Dr. Wang Haifeng of Chengdu Aircraft Corporation disclosed that China had initiated preliminary research, targeting operational readiness by 2035. The program has progressed, with concepts evolving to include tailless configurations, advanced propulsion, and unmanned aerial vehicle integration.

Reports in 2021 indicated wind tunnel testing of a tailless fighter design, foreshadowing the J-36’s development. These efforts culminated in the late 2024 public test flight, generating speculation about its role in China’s future air strategy.

Satellite imagery from Planet Labs confirms the construction of a specialized shelter between November and December last year, capable of housing the aircraft’s large wingspan. This shelter allows pre-flight preparations and final checks to be conducted with minimal exposure to onlookers and satellites while protecting the aircraft from weather conditions.

J-36: Big Lead Forward

The J-36 represents a significant advancement in China’s combat aircraft design, emphasizing stealth, advanced engineering, and modern warfare capabilities.

Its tailless flying wing configuration and trijet setup aim to reduce radar visibility. The design includes side and dorsal air intakes and a low-observable exhaust system, minimizing radar and infrared signatures.

The airframe incorporates advanced radar-absorbing materials to reduce electromagnetic wave reflections across a broad frequency range. Redesigned nozzles, intake fan structures, and integrated cooling systems mitigate heat emissions, reducing its infrared signature.

These features position the J-36 as a formidable stealth platform comparable to fifth and sixth-generation fighters.

Alex Hollings, a defense analyst, notes that the J-36’s unique design and multi-role potential position it as a “serious contender in the evolving landscape of air warfare,” capable of challenging the dominance of U.S. platforms.

Beyond stealth, the J-36 possesses operational capabilities, with an estimated maximum speed of Mach 2.5 and a combat radius of approximately 3,000 kilometers.

The blended fuselage and double delta wing design provide internal storage for fuel and weaponry, enabling extended missions without compromising radar invisibility. The aircraft’s weapon systems complement its low-observable design.

A central internal weapons bay accommodates long-range missiles like the PL-17, with side bays for munitions like the PL-12 air-to-air or YJ-12 anti-ship missiles. This configuration allows for adaptability, prioritizing air superiority or ground-strike missions. Internal armament stowage maintains its stealth profile.

The J-36 integrates advanced electronic warfare systems, enhancing situational awareness and survivability. Sophisticated sensors and electronic systems facilitate coordination with other units, including drones and autonomous systems, functioning as a command platform in networked combat scenarios.

What Makes The J-36 Unique?

The J-36 distinguishes itself with advanced features. Its large flying wing design enhances stealth by reducing its radar signature. The aircraft likely employs radar-absorbing materials to improve broadband stealth capabilities.

The aircraft is believed to be powered by three modified engines, potentially WS-10 or WS-15 models. Future designs may incorporate ramjet or variable-cycle engines. These propulsion systems could enable supercruise, allowing supersonic flight without afterburners, improving efficiency and range.

Bill Sweetman, writing for the Australian Strategic Policy Institute, speculated that the J-36 could serve as a supercruising launching platform for long-range missiles and a command and control hub for other manned and unmanned aircraft. He also suggested that the J-36’s overall size and flight performance should be categorized as a new category of aircraft, which he named the “airborne cruiser.”

The J-36 features next-generation avionics, including advanced sensors, electro-optical systems, and potentially side-looking radar arrays.

These technologies enable seamless integration into networked operations, facilitating coordination with unmanned systems. The aircraft offers payload flexibility. Its primary weapons bay accommodates long-range air-to-air missiles, such as the PL-17, and substantial air-to-ground munitions. This versatility allows for a wide range of roles, including air superiority and precision strikes.

Challenges & Questions

The J-36 faces challenges that could impact its development and deployment. Performance validation remains a key concern. Despite test flights, real-world capabilities remain unproven. Mass production presents another significant challenge. Scaling up production while maintaining advanced features is complex.

The Chinese aviation industry must address logistical and technical hurdles to ensure quality and cost-efficiency. The aircraft’s intended role remains a subject of debate. Analysts suggest the J-36’s size and payload capacity could make it suitable for various roles, including air superiority, interception, and regional bombing.

Justin Bronk of the Royal United Services Institute notes that “the reliance on crewed aircraft like the J-36 highlights their enduring value in contested environments where electronic warfare could disrupt uncrewed systems.”

The lack of official confirmation from the Chinese government adds to these uncertainties. No official statements regarding its specifications, intended use, or deployment timeline have been made. This silence has led to speculation, with some suggesting it may be a deliberate strategy to create uncertainty.

J-36: China’s Response to U.S. B-21 Raider?

The J-36 is viewed as China’s potential response to the U.S. B-21 Raider and Next-Generation Air Dominance (NGAD) fighter program. It reflects a strategic effort to compete with U.S. technological advancements.

The B-21 Raider is a long-range stealth bomber, while the NGAD focuses on air superiority through advanced stealth, sensor integration, and networked warfare. China appears to be merging similar capabilities into the J-36, presenting it as a multi-role aircraft.

The J-36’s tailless design and stealth characteristics parallel the radar-evading qualities of the B-21 and NGAD. Its propulsion system, with the potential for variable-cycle adaptation, emphasizes speed, range, and versatility.

The J-36’s ability to carry air-to-air and air-to-ground munitions highlights its multifunctional design. Strategically, it could enable China to project power across the Asia-Pacific region, similar to how the B-21 and NGAD secure U.S. interests.

However, questions remain about whether China can match the technological reliability and integration demonstrated by the U.S. platforms.

Some analysts caution against attributing too much weight to its development, arguing that its presence “merely reflects the emergence of genuine competition” rather than Chinese dominance in tactical aviation.

Rick Joe’s article for The Diplomat presents several key debates regarding the J-36’s development and implications. Joe cautions against prematurely attributing “Chinese leadership” in tactical aviation to the J-36, stating that such a position is “foolish” and that its emergence “merely reflects the emergence of genuine competition.”

The classification of the J-36 as a “sixth-generation” aircraft is also debated, with some experts suggesting it would be premature to define the J-36 as sixth-generation alone before the U.S. NGAD program reaches full maturity.

There is also uncertainty regarding its primary role, with ongoing discussions about whether it serves as a true bomber despite observable traits that may not fully align with such a classification.

The aircraft’s powerplant remains an enigma, and speculation over whether future variants might integrate variable-cycle engines persists. Some argue that the J-36 could force the U.S. Air Force into a response similar to the development of the F-15 following the MiG-25, though this perspective has been dismissed as “misguided.”

Nevertheless, the reappearance of the J-36 has drawn renewed attention from military analysts and defense experts.

While some remain skeptical about its operational maturity, China continues to test and refine the aircraft. However, its exact capabilities and place within the broader military landscape remain debatable till more information is available.
