B-21 is characterized here as an attempt to turn B-2 experience into a more affordable aircraft that can be produced in quantity. The comparison includes the difficulty and expense of sustaining the earlier aircraft. A brief disagreement concerns whether to call B-21 mature or to emphasize the continuing immaturity of B-2. Both formulations point to using lessons from the earlier system in its successor.
