Description

 The J-20S is based on the J-20 airframe, with a lengthened canopy to accommodate a second seat. The second crew member is not tasked with training but operates as a mission systems officer responsible for managing electronic warfare tasks, coordinating long-range strike missions, controlling stealth drones such as loyal wingmen, and overseeing real-time network-centric operations. This dual-crew layout is intended to reduce pilot workload and improve mission effectiveness, particularly during extended-range operations. The J-20 is estimated to have nearly double the combat radius of U.S. F-22 or F-35 fighters.

   The J-20S possibly in a command and coordination role. It is positioned not only as an air superiority fighter but also as an airborne tactical node capable of managing manned and unmanned systems, including future platforms such as the Dark Sword UCAV. This capability aligns with future network-centric warfare concepts that require real-time sensor fusion and coordinated decision-making in contested environments.
