I mean the J20 has half the payload capability minus the bunker busters at like 1/3 of the radar cross section. Building a B2 which is last gen technology and cost 2 bil when the J20 can be made for 150m is pointless. The B21 on other hand supposedly have the same cross section as the F22 but it hasn’t been shown flying or even operable. The only proof of it existing are press pictures and obvious satellite decoys. So right now the only true stealth aircraft is the F22 but its payload is garbage. And the F22 can no longer be reproduced because ‘reasons/DEI.’
