H-20 bomber (with H-X, JH-XX)

My point was that while H-20 should be designed for launching hypersonic weapons with 2000-3000km range, a different platform should be utilized for even larger air launched hypersonic weapons with potentially 5000-8000km range, and that such a platform would diverge significantly from the H-20 in terms design characteristics and requirements. I interpreted the original discussion as concerning the need for a bomber to carry missiles even larger than the Beijing heavy hammer (13m+ missile, which I believed is substantially larger than what a 2000-3000km range hypersonic weapon to be).

My point is if you’re going for intercontinental ranges then there’s no point firing them from the air to begin with.

IMO, personally I'm thinking of this, a true diamond shaped aircraft which would allow for long weapon bay while also maintaining ELO as it also like B-21/B-2's shaping has only 4 angles where everything is aligned to. As I recall, I'm pretty sure some people were calling into question the survivability of B-21. I feel like having similar level of stealth should be a given at this point, US air defenses are still pretty potent, and they are actively trying to modernise it against stealthy aircraft.

The survivability of B-21 is in context of it conducting much closer in raids.

The H-20 we are talking about would be conducting initial high end missions at distances of 2000-3000km away from its target.


As for planform, what you've depicted is somewhat close to what I also imagine but I think it is a little bit too extreme. Something like below (with approximate characteristics), with B-2 for scale.
It's just for illustrative purposes of something I have in mind, the exact detailed numbers aren't so important (for a 10mg or even 15m length weapon bay you could probably make do with a smaller aircraft, like 30m length, 24m span)

Fair enough, might as well just make the missile itself larger if additional range is required at that point. But wasn't it the Guancha trio suggesting that ALBM even larger than the Beijing hammer are in the pipeline (or maybe I misinterpreted)?

Thing with that planform is that it'll have worse RCS than B-21's planform, actually from this study, it's quite a bit worse overall although B-21's planform has higher spike at the one angle where everything is aligned to. Which is why I think cranked arrow design should be ruled out for an ELO/ULO strategic bomber.
Where is the plots from?

Hopeless Diamond is hopeless for a reason.

What would be the rough range and payload of this aircraft?
