LOL nobody reads thisWe don't know. Not yet. It's intended to fight China. So. What does that tell us?
We know it needs far, far longer range than the F-22 without tanker support. We know it needs much better stealth against the Chinese, since their sensors are better than the Russians now. We know it needs a deeper magazine, because sorties will take a long time from a 'safe' base to the target. It, like the B-21, is likely to use the ADVENT-like engines, but then the fighter sized ones are likely to be retrofited into the F-35As, if not Cs.
Past that...who knows. We can speculate based on what has been said and discussed, but...it's just fun speculation.
And I have to wonder if we need a different thread again. geez. This isn't a bomber. lol.
the real expensive is going to be a transition to 'optionally unmanned', I guess
anyway let's wait and see if the US will be able to pile up this kind of 'products'
