No reason for a mock-up to have intake covers (I think)Is that a mockup? Seems to have scratches over the airframe.
Will we be seeing FC-31/J-31 being incorporated in to the PLAAF or will it be only a naval fighter ? And what about China's export designated stealth fighter ? A lot of nations who are unable to source F-35 are possibly willing to commission a stealth fighter in their air force with in next decade or so (like UAE, Saudi Arabia, Algeria, Egypt, Pakistan, Morocco , Thailand , few Latin American countries ,perhaps even European country like Serbia).
