Northrop Grumman B-21 Raider (LRS-B)

Interesting that rather than having split surfaces they deflect the inner ailerons down and the outer ones up.

It was clear from the beginning

Similar to how many European designs control yaw. It's a simpler/lower cost/lighter weight solution to the split aileron design.

Look at the aerodynamic control surfaces. Notice the amount of deflection.

That's because it was obviously at very low speed. Which we also know since the aux. air inlets are open as well.
