China's J-36 Heavy Stealth Jet Reveals New Design Tweaks During Testing

China’s Chengdu Aircraft Corporation has unveiled fresh details about its advanced J-36 heavy stealth tactical jet through recent flight tests. The latest round of testing provided unique insights into the evolving design, particularly focusing on changes to the aircraft's exhaust systems and overall dimensions.

The J-36 first made headlines in December 2024 when it was revealed alongside another next-generation tailless fighter known as the J-XDS. Since then, at least four prototypes have been observed in flight, each showcasing significant design modifications that reflect ongoing development efforts. The most recent video footage captures a J-36 prototype during landing, offering clear views of its distinctive three-engine configuration and side-by-side cockpit layout.

One of the notable changes highlighted by this testing phase is the transition from trough-style exhausts to two-dimensional thrust-vectoring nozzles similar to those found on the U.S. F-22 Raptor. This shift suggests enhanced maneuverability and stealth capabilities for the J-36. Additionally, the aircraft now features divertless supersonic intakes (DSIs) across its entire surface, not just on top, further improving aerodynamic efficiency.

The latest video also highlights the broad width of the J-36, emphasizing its role as a heavy tactical jet designed to carry substantial payloads and equipment. This expansive design allows for the integration of advanced radar systems and communication suites essential for modern combat operations.

During the most recent flight test, observers noted distinctive lighter-colored sections on the aircraft's radome and dorsal air intake. These markings are believed to indicate the installation of operational radar in the nose section, a significant milestone in the J-36’s development. The presence of these features suggests that the jet is nearing readiness for full-scale deployment.

Experts speculate that the J-36 could serve multiple roles beyond traditional combat missions, including intelligence gathering and communications relay functions. Its large radome area and conformal antennas positioned on top of the fuselage are indicative of advanced sensor suites capable of supporting complex network-centric warfare strategies. This versatility is particularly relevant in light of China’s growing fleet of advanced air combat drones.

As development continues, there has been speculation about potential future upgrades for the J-36, including the integration of a laser directed-energy weapon system. Such enhancements would further solidify the aircraft's position as a cutting-edge platform within China's expanding military arsenal.
