If GJ-11/21 are medium altitude - medium endurance strike and ISR stealth UAVs then these longer wingspan, shorter length to wingspan ratio flying wings are high altitude capable - long endurance strike and ISR stealth UAVs.
Manned platform in H-20, unmanned platforms would be expected to significantly outnumber manned. Since GJ-11/21 is vastly more limited in range compared to H-20 which is expected to be strategic ie intercontinental ranged, then these new UAVs could be the long range strike and ISR platforms for the stealth end of the PLA's UAV arsenal. CH-7 is ISR only. These two (B-21 wingspan and the latest diamond fuselage) could be long range strike oriented. You don't need that many types of stealth, long range and endurance ISR UAVs.
There's already WZ-7, WZ-8, WZ-9, WZ-10, and CH-7 for HALE ISR with WZ-8 and CH-7 as stealth platforms.
Only GJ-11 satisfies the requirement for stealth strike and even then it's not able to operate at 2nd island chain from coastal base (not counting GJ-21 carrier version because it has carrier's range). PLA was missing long range, unmanned, stealth strike UAV. There must be at least one. These look like they have at least 3000km operational radius with those sweep angles and wingspan.
Air superiority side is covered by the UADFs.
China is absolutely lapping the US not just once. The US hasn't even got a single stealth strike UAV even of medium range yet. They want their tiny CCAs to perform strike. Probably smarter than getting those jokes (college level projects) to perform air superiority. Chinese UADFs are supersonic and use 140KN engines while US CCAs that are still just getting into flight testing are using 30KN engines or less. Within 10 years China would be 1 generation ahead of the US in manned air superiority and 2.5 generations ahead in unmanned. It's already 1.5 generation ahead of US in unmanned.
US has no GJ-11 equivalent. US has nowhere near a UADF that approaches the shadow of Type A and Type B. This is a 1,5 gen lag since US hasn't even managed to field a single 0.5 gen small CCA. By the time their small CCAs are operational, Type A and Type B would have successors.
Overtaking point has happened a while ago but it isn't clear yet because China is still amassing equal size. But China's platforms are more modern now. Even in the air where US is keen to maintain their usual gap. They've failed already. Only possible gap is submarines and even there China's caught up in base tech. US hasn't moved forward much in the last 20 years to be honest whereas China's been absolutely exponential.
