Hmm. Not sure what to think. Would we announce that we could track the J-20? I don't think so. Better to allow the illusion of unbeatable stealth than to broadcast that we can see them, track them and kill them. I definitely don't know for sure but I'm betting this is bullshit/propaganda for the home folk.
