7338213582_de7024d0aa_oA Tu-154 electronic warfare aircraft of the People’s Liberation Army Air Force and a Y-12 utility aircraft of China’s State Oceanic Administration entered the Japanese air defense identification zone (ADIZ) simultaneously on Feb. 21, according to the state-run China News Service. The Japanese defense ministry first reported on Friday that a Chinese Tu-154 was detected near the border of its ADIZ while another aircraft, a Y-12, flew into the zone and was spotted 140 kilometers away from the disputed Diaoyutai islands (Senkaku to Japan, Diaoyu to China). The F-15J fighters of the Japan Air Self Defense Force were ordered to scramble and intercept the intruding Chinese aircraft, the defense ministry said. Observers note that the Tu-154 may have been deployed to the Diaoyutai region to collect critical data on the Japanese military.
