How long until cameras with AI and night vision and so forth can easily detect any aircraft no matter how small its radar cross-section? I suspect a lot of money is being poured down a hole when it comes to “stealth” aircraft.
So it's not really a heavy bomber at all.
Great that it's got a tiny radar return, but you'll need TEN of them to get even the effect of one B-1B.
Now the B-21 may be cancelled due to budget short falls and changing AF needs.
