Could Britain or Australia obtain B-21?

Would the United States be willing to sell B-21 before it becomes obsolete?

That remains uncertain in the exchange. Clarke argues that Britain and Australia could be considered because of AUKUS, without identifying an approved sale.

A British B-21 purchase depends on American willingness to sell the aircraft, which is questioned by comparison with restrictions around B-2 and F-22. Clarke identifies Britain and Australia as possible exceptions, citing their AUKUS technology relationship. No export approval or purchase decision is identified, leaving access a possibility in the debate.
