The B-2 uses airbrakes at the wingtips. Actuate the right airbrake to yaw right, etc. You can also use differential throttle of two engines to achieve the same thing.
I meant more left/right thrust to control yaw without sacrificing your stealthy edges, not necessarily the full f-22 capabilities. Ie, not needing to actuate control surfaces on the wings (or minimize the need), in the context of not having a vertical stabilizer.
Iirc, the B-2 has to "hide" certain control surfaces momentarily when getting pulsed with radar.
