The Global Times website on April 22, 2015, said China is making significant progress on the next version of its J-20 stealth and published photographs  showing a modified Tupolev Tu-204 passenger plane suggesting clues to the J-20's radar system. The photos show that canards, or a small set of forewings placed in front of the main wings on a fixed wing craft, were installed on the passenger airplane. It suggests the radar of future J-20 models will be located on the wings like the US F-22 Raptor developed by Lockheed Martin.
