And its freakin' huge!  This has to be a strike or interceptor.  Either would make sense and both are holes in the Chinese Air Armada.  An interceptor designed to go after AWACS and tankers would seem to be perfect for a semi-stealthy long range airplane...especially if its equipped with ultra-long range Russian AAM's.

Or the Chinese equivalent of what the B-1 was suppose to be...a deep strike airplane.  The Chinese are mostly operating OLD Russian Bear type bombers in that role.  It would also make sense for them to try for a replacement.

Either way, the response from the Defense Dept will be telling.

PS.
What's with the door to the main landing gear???
