China's TB-001 Long-Endurance Reconnaissance and Attack Drone Flight Puts Japan on High Alert in East China Sea

A Chinese PLA TB-001 twin-boom long-endurance drone conducted a reconnaissance and surveillance flight in the East China Sea that triggered a Japanese Air Self-Defense Force alert response. The TB-001 is capable of carrying precision-guided munitions in addition to its sensor payload, giving it both ISR and attack roles. The incursion reflects China's increasing use of military UAS for persistent maritime domain awareness around the Japanese archipelago. Japan scrambled fighters in response, highlighting escalating aerial grey zone activity in the region.
