You guys are getting too worked up about that article. If you read it closely, no where in the article did it actually confirm that the Su-30 acquired or locked onto the J-20. All of it is just speculation by the author. That said, what did you guys expect the IAF spokesperson to tell the general public? That the J-20 can't be detected and the IAF has no way to engage it? Of course they are going to play up their own capabilities unless they need fundings for better weapon acquisition. Need I remind you guys that the Chinese military also claimed that they could track F-22s a while back?The Indians just feel that they are the center of attention for all PLA operations ... which basically amounts to exaggerated self-importance. They think that their air force is of such high priority that the Chinese would send J-20s to the border. Classic self delusion.
