If the B-2 were a bit more realistic
I updated the tail, removed engine 2 and put a turret in its place.
Removed the robotics refuelling probe because it was kinda bad and put a static probe in its place.
Slight performance decrease due to the removal of engine 2, takes longer to climb to altitude. The B-2B is still able to reach the speeds the original did.
~1200m/s at ~17km is most economic for high speed flight.
