Just from a quick look, judging from the rear end shot, they could VERY easily give it 2-D thrust vectoring like the F-22 has if they needed pitch authority for high G maneuvers.
It looks a bit like the F117 to reduce IR signature.
This aircraft looks to have a very high level of stealth shaping and planform alignment. However from the wording it does not use exotic materials to get an ultra low radar signature. I would call this budget stealth. There is a point of diminishing returns when it comes to stealth so this design clearly has all the bang for buck stealth features. If this aircraft crashed behind enemy lines it might not have the exotic F-35 materials technology and this is what would prevent it from being exported.
A wonder what engine it uses. I think a Rolls-Royce AE 3007 as used on the Boeing MQ-25 Stingray would make sense. No US export restrictions and it has enough thrust for a 15t MTOW.
The F404 would also be likely. Even without afterburner it would allow for a potential higher mach 1.2 top speed. With afterburner it would put this aircraft in a different class. The first supersonic, stealth armed drone.
