J-36 Has Been Spotted Conducting Its Third Test Flight

The Chengdu J-36 has taken to the skies today in its latest public test flight, marking another pivotal moment in its development. Over the past months, the aircraft has been seen in three key demonstrations the first on 26 December 2024, the second on 17 March 2025, and now today on 25 March 2025. Each flight has provided fresh insights into the capabilities of this highly anticipated platform, drawing global attention to China’s ambitious push into sixth-generation fighter technology.

Development and Historical Milestones

The Chengdu J-36, a speculative designation given by military analysts to a trijet, tailless double-delta winged aircraft, has evolved rapidly. In January 2019, Dr. Wang Haifeng of Chengdu Aircraft Corporation announced the commencement of pre-research into a sixth-generation fighter, with expectations that the project might reach fruition by 2035. Earlier in 2018, CAC submitted multiple design proposals, and tests in low-altitude wind tunnels highlighted several innovative configurations. A sighting in October 2021 of a tailless fighter at CAC’s facilities further fueled speculation about this next-generation project.

Public Appearances and Flight Timeline

The aircraft’s journey into public view began on 26 December 2024, when images and videos emerged of a prototype flying around a CAC-owned airport in Chengdu. Observers noted the aircraft was marked with the code “36,” leading analysts to tentatively identify it as the J-36. The momentum continued on 17 March 2025, when further test footage showcased the prototype’s trijet configuration equipped with afterburners, a dorsal intake with a diverterless supersonic inlet, and distinctive split ruddervons along the outer trailing edges of its wings. Now, today 25 March 2025 the newest test flight reinforces these findings, adding valuable data to the aircraft’s flight envelope and operational capabilities.

Innovative Design and Technical Specifications

At the heart of the J-36’s appeal is its revolutionary design. This aircraft features a trijet, tailless flying wing layout with a blended, diamond-like double-delta wing configuration. With an estimated length ranging between 20 and 26 meters and a wingspan around 20 meters, the aircraft boasts a wing area exceeding 190 square meters and a maximum take-off weight estimated between 100,000 and 120,000 pounds. Its design emphasizes all-aspect broadband stealth, supercruise capability, long endurance, and multispectral situational awareness. Analysts speculate that the fighter is powered by three modified variants of the WS-10 or WS-15 engines, though possibilities of integrating advanced propulsion systems remain under discussion.

Aerodynamic Innovations

The J-36’s advanced aerodynamic profile is one of its defining features. The double-delta wing design not only enhances maneuverability but also optimizes performance for supercruise maintaining supersonic flight without afterburners. A thin, wide nose section with integrated radomes, electro-optical windows, and leading-edge extensions underscores the aircraft’s stealth and sensor capabilities. Additionally, the unique configuration featuring dual under-wing inlets and a dorsal intake with a diverterless supersonic inlet works to minimize the radar cross-section while ensuring efficient engine performance.

The Role of Chengdu Aircraft Corporation

Chengdu Aircraft Corporation has long been synonymous with pioneering military aerospace developments. The company’s continuous innovation is now on full display with the J-36. Although Chinese state media and official defense sources have remained silent on the project, the strategic timing of these public test flights has generated significant international interest. The ongoing tests not only validate years of research and development but also signal CAC’s readiness to push the boundaries of modern fighter technology.

Global Context: The Sixth Generation Race

The emergence of the J-36 comes amid a global race to develop sixth-generation fighter aircraft. U.S. Air Force leaders and international defense analysts have observed that China is employing a “system of systems” approach to achieve exponential improvements in stealth, processing power, and sensor integration. Similar ambitious projects from other defense powers add context to the competitive atmosphere driving innovation in military aviation. The J-36’s progression is seen as a crucial piece in this broader strategic puzzle, influencing both regional and global balances of power.

Analyzing the Flight Test Data

The flight tests on 26 December 2024, 17 March 2025, and today’s flight on 25 March 2025 have collectively provided unprecedented insights into the J-36’s capabilities. The initial public appearance confirmed key design elements, while the subsequent flights have showcased significant enhancements in propulsion, stealth performance, and aerodynamic control. Today’s test flight, in particular, adds to the growing body of evidence that the J-36 is rapidly evolving. The data indicates improvements in afterburner performance, engine response, and overall flight stability critical factors for a fighter expected to perform in high-intensity combat scenarios.

Technical Insights and Future Potential

A closer examination of the J-36 reveals an aircraft built for future conflicts. Its expansive weapons bay measuring roughly 7.6 meters suggests the capability to house a variety of armaments, including beyond-visual-range missiles like the PL-17 or larger air-to-surface munitions. Additionally, advanced sensor arrays and a state-of-the-art digital cockpit interface imply that the aircraft will operate as part of a network-centric battlefield, potentially coordinating with unmanned systems for enhanced situational awareness. These technical advancements hint at the transformative role the J-36 could play in next-generation combat operations.
