Earlier this month Japan released some details about the growth of incursions by Chinese aircraft into Japanese airspace. The release of information comes after China unilaterally declared the establishment of its East China SeaADIZ (air defense identification zone) last November. The figures show a significant rise in the number of interceptions being launched by the JASDF (Japan air self-defence force) against Chinese intruders.
The Japanese ministry of defense has not released scramble figures for 2013 but does note that Chinese activity has continued at a high rate. Shaanxi Y-8J airborne early-warning aircraft (believed to be fitted with Searchwater 2000 radar) of the Chinese naval air arm have transited through the Japanese ADIZ between Okinawa and Miyakojima and out into the Pacific on several occasions, as have Xian H-6 missile-carriers. The JASDF also intercepted a Harbin BZK-005 surveillance UAV in the ADIZnear the Diaoyu Islands.
On November 23 China established its East China Sea ADIZ without warning, drawing international criticism and strong condemnation from Japan. Crucially, the ChineseADIZ extension overlaps part of Japan’s ADIZ, including the airspace around the Senkaku Islands. It also overlaps a portion of South Korea’s ADIZ in the north, and that of Taiwan to the south. On the day of the ADIZ extension, China flew Tupolev Tu-154MDType II and Shaanxi Y-8CB signals intelligence aircraft into the East China Sea up to the new edge of the Chinese ADIZ, and within that of Japan.
In riposte, three days later two U.S. Air Force B-52 bombers flew through the zone without notification to Chinese authorities. On January 31 this year China reported that it had launched two armed Sukhoi Su-30MKK fighters to intercept Japanese military aircraft in the East China Sea zone, although Japan did not confirm that the event had taken place.
