Video footage shows China’s new sixth-generation J-36 stealth fighter jet performing a test flight maneuver. The rare sighting underscores Beijing’s push for airpower dominance and raises fresh concerns about U.S. and allied security.
Since 29th of September, the video footages of China’s sixth-generation stealth fighter jet, the J-36, have ignited global scrutiny as images appeared from several angles taken and published on social media. Captured during a high-speed test sortie, the jet is seen executing a vertical loop, with landing gear fully retracted and aerodynamic control surfaces playing a visible role in its flight path. This rare glimpse into an aircraft long shrouded in secrecy marks a significant milestone in the evolution of China’s airpower and raises serious questions about future air superiority dynamics.

The J-36, now entering advanced test phases, is understood to be developed by Chengdu Aircraft Industry Group and represents China’s most ambitious leap into next-generation air dominance. With a distinctive three-engine configuration and a smooth, radar-evading profile, the aircraft’s silhouette is as exotic as it is intentional. The new footage reveals sleek shaping and serrated-edge exhausts reminiscent of the F-22 Raptor, suggesting aerodynamic refinements intended to enhance stealth and maneuverability. Such design features are typically found only on elite platforms and allow the aircraft to sustain maneuverability beyond conventional aerodynamic limits.
The J-36’s development timeline is progressing at a pace that has caught many analysts by surprise. First spotted over Chengdu on December 26, 2024, the aircraft’s early test flights were thought to be basic airframe evaluations. However, these latest demonstrations of high-energy maneuvering, such as the Nesterov loop seen in recent footage, suggest that the platform has already achieved a high level of flight control integration. The Chengdu team appears to be incorporating past experience from the J-20 stealth fighter program while pushing deeper into realms explored only conceptually by U.S. and Russian sixth-gen projects. What was once speculative is now unmistakably airborne.
Technically, the J-36’s capability to perform a complete vertical loop at medium to high subsonic speeds sets it apart from most modern fighters. While the F-22 has long been the benchmark for post-stall maneuverability, the J-36’s three-engine configuration likely offers a higher thrust-to-weight ratio and energy efficiency. Compared to the F-35, which prioritizes digital dominance and multirole adaptability over raw aerodynamic performance, the J-36 represents a return to pure air combat excellence, emphasizing agility, speed, and vertical envelope.
Beyond the engineering, the J-36 holds enormous geopolitical weight. In a moment when tensions in the Taiwan Strait and South China Sea are escalating, China’s public exposure of the aircraft’s maneuvering capability serves as both deterrent and demonstration. By fielding a platform that appears capable of challenging U.S. and allied air superiority, Beijing is shifting the psychological and tactical framework of regional power projection. The ability to operate above traditional air defenses or intercept advanced threats places the J-36 at the center of a new operational doctrine, one that blends air superiority, space denial, and electronic dominance in a single platform.
This latest phase of testing, featuring a full vertical loop at speed, has reshaped global perceptions of what China’s sixth-generation ambitions truly entail. The J-36 is no longer just a conceptual adversary; it is a functioning aircraft performing advanced tactical maneuvers before the world’s eyes. For Western defense planners, this means the era of unilateral aerial dominance may be drawing to a close, and the next generation of competition is already in flight.
