Chinese carrier jets lock fire-control radar on Japanese fighters near Okinawa

Force in Play

Aligning with Japan in calling out unsafe Chinese military behavior

On December 6, 2025, two Chinese J-15 carrier-based fighter jets from the aircraft carrier Liaoning intermittently illuminated their fire-control radar on Japanese Air Self-Defense Force (ASDF) F-15 fighters over international waters southeast of Okinawa, in two encounters lasting roughly three minutes and about thirty minutes respectively. Japan’s defense minister Shinjiro Koizumi denounced the radar lock-ons—which militaries treat as the step immediately before weapons launch—as “dangerous” and “extremely regrettable,” and Tokyo lodged a formal protest with Beijing. Analysts noted this was the first publicly acknowledged fire-control radar lock between Chinese and Japanese military aircraft, echoing a 2013 episode when a Chinese frigate locked weapons radar on a Japanese destroyer near the disputed Senkaku/Diaoyu Islands.
