To understand the significance of the J-36 fighter, it is useful to examine China’s previous stealth fighter developments:

The J-20 Mighty Dragon was China’s first attempt at competing with the F-22 Raptor and F-35 Lightning II, but despite its stealth features, it still relies on non-thrust-vectoring engines and lacks sixth-generation capabilities such as AI-assisted avionics and next-generation weapon systems. The China J-36 stealth fighter is expected to overcome these limitations, making it the most advanced Chinese fighter jet ever developed.

Design and Technical Specifications of the Chengdu J-36

The Chengdu J-36 fighter is expected to introduce several revolutionary design elements that set it apart from previous Chinese stealth fighters like the J-20 and J-35. Analysts speculate that the China J-36 stealth fighter will feature a tailless diamond-delta wing configuration, advanced stealth coatings, and a high level of artificial intelligence (AI) integration.

While official specifications remain classified, leaked details and satellite imagery from Chinese testing facilities provide a glimpse into the possible technical features of the J-36 fighter jet.

Tailless Diamond-Delta Wing Configuration

One of the most notable aspects of the J-36 fighter jet is its tailless diamond-delta wing design. This layout is a departure from previous Chinese stealth aircraft, such as the J-20, which uses canards and a traditional tail stabilizer.

Advantages of a Tailless Diamond-Delta Wing

• Enhanced Stealth: Reduces radar cross-section (RCS) by eliminating vertical stabilizers, which are a major source of radar reflections.
• High-Speed Maneuverability: Improves aerodynamic efficiency for high-altitude, high-speed engagements.
• Fuel Efficiency & Range: Provides more internal fuel storage, extending operational range.
• Superior Dogfighting Performance: Allows for better agility and sustained turns in combat.

A similar tailless stealth design has been observed in American and European sixth-generation fighter concepts, such as the U.S. NGAD and the UK-led Tempest. This suggests that the Chinese J36 fighter is being developed in line with global trends in next-generation air combat.

Trijet Engine Setup: Power and Speed

Early reports indicate that the J-36 Chinese fighter could feature a trijet propulsion system, which would be an unusual but significant departure from traditional twin-engine fighter designs. This setup could provide several advantages:

The exact engine model is unknown, but speculation suggests that the J-36 fighter jet could be powered by an advanced version of the WS-15 or WS-10C engines, both of which are being developed for high-performance stealth fighters.

If the China J-36 fighter achieves supercruise and sustained hypersonic flight, it could significantly outperform current fifth-generation aircraft in both speed and range.

Stealth Capabilities of the J-36 Fighter

China has made significant progress in stealth technology, and the J-36 fighter jet is expected to incorporate cutting-edge radar-evading features, such as:

• Radar-Absorbing Materials (RAM): Advanced composite coatings to reduce detectability by enemy radars.
• Internal Weapons Bays: Concealed missile storage to maintain low observability.
• Electronic Warfare (EW) Systems: Ability to jam enemy radars and disrupt missile guidance systems.
• Infrared Signature Reduction: Engine exhaust shaping to minimize heat emissions, making it harder to detect with infrared sensors.

The Chinese 6th generation fighter could also use plasma-based stealth technology, a theoretical concept that involves ionizing air particles around the aircraft to absorb radar waves. If successful, this could make the J-36 fighter one of the most elusive aircraft in the world.

Weapon Systems and Payload of the Chengdu J-36

The Chengdu J-36 fighter jet is expected to feature a highly advanced weapons system designed for next-generation air superiority, long-range strike missions, and electronic warfare. As a sixth-generation fighter, the China J-36 stealth fighter will likely move beyond traditional air-to-air combat by integrating hypersonic missiles, directed energy weapons, and AI-assisted targeting systems.

Internal Weapons Bay: Maximizing Stealth and Firepower

Like other stealth fighters, the Chinese J36 fighter will likely incorporate internal weapons bays to reduce radar cross-section (RCS). By housing weapons inside the fuselage rather than on external hardpoints, the J-36 fighter will maintain a low observability profile, making it harder for enemy radars to detect.

The expected weapons payload for the China J-36 fighter jet could include:

With sixth-generation capabilities, the J-36 fighter jet will likely integrate hypersonic missile technology, allowing it to engage targets at unprecedented speeds and ranges.

The PL-15, a long-range air-to-air missile, already gives China’s current fighters an edge over Western aircraft, and an improved variant of the PL-15 or a next-generation PL-21 could be the main armament for the Chinese J-36 fighter.

AI-Enhanced Targeting and Drone Coordination

One of the most revolutionary aspects of China’s sixth-generation fighter will be artificial intelligence (AI) integration. The J-36 fighter is expected to feature AI-assisted targeting, allowing the aircraft to:

• Track and engage multiple targets simultaneously with minimal pilot workload.
• Operate in a “loyal wingman” system, commanding unmanned combat aerial vehicles (UCAVs) to assist in missions.
• Autonomously identify and avoid enemy threats, enhancing situational awareness.
• Coordinate with space-based sensors for better real-time target acquisition.

This level of AI-driven warfare could make the J-36 Chinese fighter a dominant force in electronic warfare and data-driven combat environments.

Future Weapon Systems: Hypersonic and Directed Energy Weapons

China has invested heavily in hypersonic missile technology, and the Chinese 6th generation fighter could be equipped with air-launched hypersonic weapons, giving it an advantage over existing fighters. Hypersonic missiles travel at Mach 5+ speeds, making them extremely difficult to intercept.

Additionally, China has explored directed energy weapons (DEWs), such as high-powered lasers and microwave systems. If integrated into the J-36 fighter jet, these could be used to:

• Destroy incoming missiles before they reach the aircraft.
• Neutralize enemy drones and electronic warfare threats.
• Disrupt enemy communication and targeting systems.

While DEW integration is still largely theoretical, it represents the future of next-generation aerial combat. The China J-36 stealth fighter could be among the first aircraft in the world to deploy these advanced energy-based weapons in real-world scenarios.
