The image below shows the radome, with the radioactive symbol next to it. You can see the start of the fuselage chine.
On the left side of the fuselage you can se a couple of air data probes.
Both the stabilators and the vertical tails are all-moving. The vertical tails can act as air brakes.
It also seems to have a drooping LEX flap these are called leading-edge vortex controllers. Then can produce a nose-down pitching moment that aids in stall recovery.
Here we can see the wing attach point as it is being moved out of its transport aircraft.
