China’s ‘sixth-gen’ fighter jet spotted with design upgrades, J-36’s fifth prototype

New photos reportedly show what may be a fifth prototype of China’s secretive J-36 sixth-generation fighter.

Analysts say the aircraft has visible changes to the airframe, engine integration, exhaust layout, intake geometry, and stealth shaping.

Beijing has not confirmed the program or its status, but the images suggest continued flight testing and refinement.

If accurate, the sightings point to China advancing an active sixth-generation combat aircraft effort and closing the gap with the U.S. in future airpower development.
