A 1999 B-2 flight manual in my collection says to hold stick slightly
into the wind during crosswind takeoff. Release rudder pedal pressure
after becoming airborne. The air data system will sense sideslip and
automatically weathervane the aircraft into the relative wind.

Crosswind approaches may be flown in a crab or with a wing low. Wings
should be leveled and crab removed before touchdown; slight elevon
will maintain wings level.

After touchdown, the flight control system ignores the yaw angle
inputs from the air data system, so it no longer tries to weathervane
into the relative wind.


Except for battle damage or collision, it's hard for me to imagine
both rudders on the same side failing. Although they normally operate
symmetrically, the upper and lower rudders are independent surfaces
with their own actuators. During takeoff they do move independently
when the stick is pulled back to rotate. The lower rudder goes to zero
and the upper rudder rises to help the elevons raise the nose.
