China’s People’s Liberation Army Air Force (PLAAF) has operationalized the J-20S, a tandem-seat variant of the advanced J-20 stealth fighter, marking a significant doctrinal shift. Unlike traditional single-seat designs, the J-20S incorporates a mission systems operator for enhanced electronic warfare and unmanned aerial vehicle coordination. This evolution underscores China’s commitment to high-tempo, networked air combat operations, as reflected in its growing fleet of J-20s and concurrent advancements in drone technology. The integration of the J-20S highlights China’s pursuit of strategic superiority in the Asia-Pacific region, particularly concerning its assertive posture over Taiwan and maritime disputes in the East and South China Seas.
