A number of Japanese government relevant persons revealed that, given the fierce disputes between Japan and China around the Diaoyu Islands (known as Jianye Islands), the Ministry of Defense has modified the Emergency Lift Standard of the Aviation Self -Defense Force.All fighters that have taken off in the Fujian Provincial Aviation Base have greatly strengthened their response measures, including the fighter aircraft that immediately allowed the empty Zheba base to lift off.

According to the Kyodo News Agency, in order to monitor the movement of Chinese military aircraft, Japanese air early warning aircraft flying over the East China Sea from sunrise to sunset.

The Japanese Ministry of Defense only obviously showed the possible violations of the airspace on the radar, and it would make the air aircraft rush off urgently.

According to the news of comprehensive related persons, in order to prevent Chinese aircraft from entering the Diaoyu Islands airspace between 25 degrees north latitude and 26 degrees north latitude, the Japanese Air Self -Defense Force set 27 degrees north latitude as a defense line.In recent years, the Chinese military aircraft surged in the south of the line, and the Ministry of Defense has increased the number of air fighters responding to 1 Chinese military aircraft from the original two to 4.

On the other hand, the Chinese military changed the lift base in Zhejiang Province to Fujian Province, which was closer to the Diaoyu Islands, and quickly promoted modern fighters such as J-11.

Naha base is about 410 kilometers from the Diaoyu Islands, and the F-15 fighter needs to fly for about 25 minutes.On the other hand, the base of Fujian Province is about 380 kilometers away from the Diaoyu Island. The J-11 needs to fly for more than 20 minutes, and the time is short.Therefore, the Ministry of Defense's judgment is necessary to immediately take off all fighters from the Fujian Provincial Base, and immediately let the Japanese fighter jet from the Naha base.
