Key Points and Summary on J-36: New details are emerging about China’s even more advanced sixth-generation fighter, the Chengdu J-36.
-First flown in prototype form on December 26, 2024, the J-36 features a radical, tailless, diamond-delta wing design and a unique trijet engine configuration.
-This “tactical bomber” appears to blend the characteristics of a stealthy, heavy-payload bomber with the speed and potential maneuverability of a fighter.
-As it races to compete with the American F-47 NGAD, the J-36 represents a significant and mysterious leap in China’s military aviation capabilities.
The J-36 Fighter Has Arrived from China
The J-36 reportedly currently exists in a single prototype airframe, built by the Chengdu Aircraft Corporation (headquartered in the eponymous capital city of Sichuan Province), the same industrial firm that manufactures the J-20 Weilong (“Mighty Dragon”) stealth fighter.
According to a 3 January 2025 article on the International Defence Analysis website, “The journey toward the J-36 began in January 2019 when Dr. Wang Haifeng, chief designer at Chengdu Aerospace Corporation (CAC), announced China’s initiation of pre-research on a sixth-generation aircraft. The program’s ambitious timeline targeted completion by 2035, demonstrating China’s commitment to advancing its military aviation capabilities.“
The CAC engineers took a methodical and thorough approach to developing this ambitious project. Eight distinct design proposals were initially submitted, four of which underwent extensive testing in low-altitude wind tunnels to ensure optimal performance characteristics.
The first significant tangible milestone in the J-36 program took place in October 2021, when observers spotted an aircraft with a tailless design at CAC facilities. Then, on 26 December 2024 (a date that coincided with Chairman Mao Zedong’s birthday), the prototype made its maiden flight, accompanied by a J-20S twin-seat chase plane.
J-36 Tech Specs and Characteristics
Though the specific details of the J-36 are obviously shrouded in secrecy, educated guesswork projects the following vital stats:
Fuselage Length: 22.5 meters (73 feet 9 inches)
Wingspan: 24 meters (78 feet 9 inches)
Wing Area: 248 square meters (2,669 square feet)
Maximum Airspeed: Mach 2.5 (1,918 mph, 3,087 km/h, 1,666 knots)
Maximum Takeoff Weight (MTOW): 55 tons (110,000 lbs.,49,985 kilograms)
Combat Radius: Approx. 3,000 kilometers (1,864 statute miles, 3,452 nautical miles)
Presumably, the J-36 will be a trijet tailless diamond-double-delta winged aircraft. The trijet aspect sets the design apart from more conventional aircraft configurations, as it incorporates two lateral air intakes with a caret (inverted V-shape) design and one dorsal air intake.
The caret inlet was first utilized in the U.S. carrier fighter F/A-18E/F Super Hornet, and the test results proved that its total pressure recovery performance was superior to that of the conventional two-dimensional inlet. And although the 4th Generation Super Hornet is undoubtedly not a stealth aircraft, the care and attention to detail in the inlet design has the added benefit of excellent stealth performance and aerodynamic capability due to the large back-sweep angle.
The aircraft is also expected to take the next step in stealth technology’s invisibility standards, incorporating new materials and design features that meet stringent testing standards for electromagnetic wave absorption across all frequency bands; these materials are expected to maintain consistent low detection characteristics when illuminated by radars from multiple angles.
The stealth capabilities will receive an additional boost from (1) the aforementioned tailless delta design that reduces its signature (with the added benefit of substantial internal volume for fuel and weapons carriage), (2) redesigned nozzle bodies that minimize radar returns, and (3) integration of cooling systems and sophisticated absorption materials contributes to both radar and infrared signature (IR) reduction.
Moreover, the J-36’s control surfaces, which include split flap rudders on the outboard wing positions, indicate a sophisticated flight control system capable of maintaining stability without traditional vertical stabilizers.
Specific weapons payload is unknown at this point, but being envisioned as a multirole combat aircraft, it wouldn’t be surprising if the J-36 ended up wielding the same weapons as the Weilong, including:
-PL-10 short-range air-to-air-missile (AAM)
-PL-12 medium-range AAM
-PL-15 long-range AAM
-PL-17 very-long-range AAM
-Lei Shi LS-6/50 and LS6/100 small-diameter precision-guided bomb (PGB)
-Fei Teng FT-7 small-diameter PGB
Big-Picture Considerations
The J-36 would presumably put the PLAAF on par with America’s Boeing B-47 Next Generation Air Dominance (NGAD) fighter and Northrop Grumman B-21 Raider bomber, Great Britain’s BAE Systems Tempest program (a joint venture between the UK, Italy, and Japan), continental Europe’s Airbus FCAS (Future Combat Air System)/Next Generation Weapon System (NGWS) and Japan’s Mitsubishi F-X in the race to field a 6th Generation warplane.
