How did the B2 Bomber achieve yaw I came across this diagram of the B2. I was wondering how it achieved yaw. If I'm correct usually the rudder on the tail would do this, but the B2 does not have a tail. Does it have no need for yaw, or does something else act as the tail?
They use differential breaking. The elevons are split, and can open up both above and below the wing to increase drag on one side, yawing the plane.
