J-50

Tailless, twin-engine stealth aircraft developed by Shenyang Aircraft Corporation, first publicly sighted flying alongside the larger Chengdu demonstrator on December 26, 2024, with additional flight-test imagery surfacing through 2026. "J-50" (also referred to as J-XD or J-XDS in some reporting) is a temporary designation used by open-source analysts and defense media; no PLA or manufacturer designation, program name, or performance specification has been officially confirmed by Chinese authorities. Caveat: dimensions, weights, speed, range and armament are not publicly documented and should be treated as unverified/speculative open-source analysis, not confirmed state or manufacturer figures.
