Does B-21 trade capability for lower cost?

Is B-21 the Virginia to B-2's Seawolf, gaining affordability at a small cost in capability?

That analogy is disputed. Clarke favors a Los Angeles-to-Virginia comparison and emphasizes the shift from a Soviet Cold War threat to Pacific and global conflict.

The question compares B-21 with Virginia and B-2 with Seawolf, asking whether lower cost implies a small loss of capability. That analogy receives mixed responses. Clarke instead compares a late Los Angeles-class submarine with a late Virginia-class boat to emphasize a generational change. His aircraft comparison distinguishes B-2's Cold War Soviet threat from the Pacific and global conflict assumptions used to explain B-21.
