That's the complete opposite of what the GCAP nations have concluded. Pushing deep into hostile territory, beyond UHF datalinks, networked with a sqn of UCAVs, sixth-gen aircraft will have to have vast amounts of computing power to process the torrent of incoming sensor data. The smart part of munitions is only useful once all that data has been processed and for timeliness that will have to happen onboard, not back in home nation.
Doctrinally it also means a delegation of targetting authority to far-forward autonomous units, but that is something most NATO-aligned nations practice to some extent.
Now maybe that means a B-21 style platform would be better for some tasks; to some degree it does sound like the original B-2 mission of hunting SS-20s far behind the FLOT. but the GCAP still sees a need for high kinematic performance as well.
For that mission I'm surprised that GCAP is single-crew, surely a second pair of hands and eyes would be a boon.
