China’s Mysterious ‘J-36’ Jet Conducts Second Test Flight

China’s Chengdu Aircraft Corporation (CAC) has reportedly conducted the second known test flight of its ‘J-36’ stealth aircraft, a tailless, trijet design that remains under evaluation.

The aircraft was seen flying over Chengdu with landing gear retracted, marking a progression from its initial sighting on Dec. 26, 2024.

New images and videos from Chinese social media captured the J-36 in flight, showing its unique dorsal air intake, broad fuselage, and triple-engine layout. The aircraft’s purpose remains unclear, with analysts debating whether it is a next-generation strike fighter or a regional bomber. The J-36 was reportedly powered by three WS-10C engines, with speculation that future versions could incorporate the WS-15 engine, which is designed for supercruise capability.

Satellite imagery from Planet Labs indicates the construction of a specialized hangar at CAC’s flight test facility, likely to conceal the aircraft from observation. The new shelter sits alongside smaller ones used for existing aircraft such as the J-10 and J-20.

The J-36 features a smooth, blended-body design, with split trailing-edge control surfaces that function as air brakes. The aircraft’s internal weapons bay remains unconfirmed, but its structure suggests capacity for long-range strike payloads. Its paint scheme appears to be a mix of black and gray, similar to other stealth aircraft.

Western analysts remain skeptical of China’s claims regarding sixth-generation capabilities, as key technological benchmarks for the classification—such as advanced networking, directed-energy weapons, or artificial intelligence integration—have not been demonstrated. The aircraft’s final role and operational potential remain subjects of analysis as testing progresses.
