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

by78

I think you are being a bit unreasonable here.

The aircraft/role that sinosoldier has referred to as JH-XX is one that has also been variously referred to as H-X, H-1X, H-18, JH-X and J-X. Huitong's stand in entry for the aircraft also acknowledges how there is yet to be a single agreed upon designation for this aircraft.

JH-XX is one of the more common stand in designations we've used on SDF and is one I've consistently used as well.

I understand there had been numerous code names for a future Chinese bomber project or projects, but that was back when we didn't know the extent of China ambition. We didn't know if China had wanted a strategic or theater bomber, or both, or if a supersonic airframe or subsonic, and so on. All we knew was that China needed and was working on a new bomber, so any vague placeholder name would do.

But then was then, and now is now.

There were and probably still are or will be three possible bomber projects, whether they are being pursued singly or concurrently, or if some have been abandoned, with each comes with a range of possible features, and each possibly with competing designs from different AVIC subsidiaries:

1) Strategic bomber project: definitely long-range, possibly stealthy, subsonic or supersonic, pure bomber.
2) Theater bomber project: definitely medium-range, possibly stealthy, subsonic or supersonic, pure bomber.
3) Fighter-bomber project: definitely medium-range, possibly stealthy, supersonic, not a pure bomber.

Based on the rumors on this forum:
For 1), project status is active; a flying-wing, subsonic, and stealthy airframe has been confirmed out of XAC. There might be other competing airframes we don't yet know of.
For 2), project status is unknown; but according to Huitong,

was once part of the project.
For 3), project status is unknown but leaning toward dormant. If being pursued, it will probably be along the lines of an enlarged J-20 or a modified Flanker.

Therefore, JH-XX as a general placeholder can no longer do, unless we gives it a greater degree of specificity, namely JH-XX is a future fighter-bomber.

Now, from Fzgfzy, we have the following photograph:

A stingray and a platypus. But fzgfzy doesn't say if they represent separate general projects or specific airframes, or if they are active or cancelled, or if they are airframes competing for the same project, or if they are each winner of a separate project, or whether they represent strategic or theater bombers or in the case of the platypus, a fighter-bomber, so on and on. There are dozens of possible combinations.

at face value, then the Platypus is a modified Flanker and therefore likely a fighter-bomber after all. But that still doesn't allow the assertion made by Sinosoldier that fzgfzy thinks there are two JH-XX designs.

I now have the May edition of Aerospace Knowledge. I've attached the pages relevant to this thread (as far as I can tell) and would appreciate a translation of anything notable.

There are also articles about the J-20 and the Z-20 (and other topics), if anyone is interested.

The central point I find in this article is about "rethinking what is the most efficient way for a long range bomber to survive and carry out the task in today's new reality". The reality being "improved anti-stealth radar working on lower frequency defeating the X-band optimized traditional stealth design". It also questioned the instinctive equation of B-2 fly wing design with the coming Chinese bomber. It argued that a fly-wing has inherent deficiency in lift generation because the Rudder (steering) and the lift generation flaps are at the same distance to the center of lift. The downward flap generated lift will be cancelled by the upward rudder which is to counter the downward motion created by the flap.

The article did not propose any alternatives to address the above mentioned questions.

However, the article suggested "instead of relying on the carrier (bomber) to get close to target undetected, use long range stealthy cruise missiles to keep the bomber further away". This suggests that the Chinese bomber may be designed around a larger weapons bay than the B-2.

My take is that keep an open mind that the Chinese strategic bomber many not look like a B-2 or B-21 at all. In the similar vein as J-20 is far different from F-22.

I understand how you have interpreted it that way, however I will offer an alternative.

First of all, the H-20. This is of course the strategic sized flying wing stealth bomber that we have all expected for a long time. Before it was settled on H-20 a few years ago, it was called various things -- H-X, H-8, H-9 etc. When fzgfzy posted that picture of the manta ray, the manta ray was reasonably assumed to be referring to H-20; a flying wing.
Then, there was also the strategic sized supersonic non-stealthy concept that was supposedly offered as a competitor to the flying wing that became H-20. We've never had any pictures of this concept nor has any designation ever been applied to it.


Now, we come to the issue that's caused the disagreement over the last few pages -- the stealthy, supersonic medium bomber/fighter bomber.
The reason why I call it a "bomber/fighter bomber" is because we don't really know if this aircraft is intended to merely be a bomber or also have some level of air to air capability.
That is why it has been called various designations over the years -- JH-XX, H-18, H-X, JH-X, H-1X etc. It really is all over the place. But these designations are all referring to the same aircraft role -- a stealthy, supersonic, medium bomber/fighter bomber.
When fzgfzy posted a picture of a platypus, it was interpreted as referring to the stealthy supersonic medium bomber/fighter bomber. With the recent pictures of the SAC nose mock up, those were also interpreted to be related to the same aircraft.
With fzgfzy recently mentioning the aircraft as H-1X and going to the northwest, and being more beautiful and more sci-fi than the SAC nose mock up, those were also all interpreted to refer to the same stealthy supersonic medium bomber/fighter bomber role.


I too would like to see a greater degree of specificity for this aircraft, but it's hard to demand that when we don't know the status of this project.


So I think it is easiest at this stage just to accept that:
1: we have no idea what the designation of this stealthy supersonic medium bomber/fighter bomber is
2: there are multiple designations that have used to refer to this aircraft in the past and we should remain vigilant to clarify which aircraft they are talking about when using this role



Finally, as for Sinosoldier saying there are "two JH-XX" designs -- again, first I believe when he says JH-XX he is of course referring to the medium stealthy supersonic bomber/fighter bomber aka H-18, H-X, JH-X, platypus.

When he says there are "two" designs, he is saying that there were two designs -- one that was worked on by SAC earlier and rejected by the PLA, and a successor/different "more beautiful" and "more sci fi" one that has supposedly been resurrected and being worked on by XAC.



There were and probably still are or will be three possible bomber projects, whether they are being pursued singly or concurrently, or if some have been abandoned, with each comes with a range of possible features, and each possibly with competing designs from different AVIC subsidiaries:

1) Strategic bomber project: definitely long-range, possibly stealthy, subsonic or supersonic, pure bomber.
2) Theater bomber project: definitely medium-range, possibly stealthy, subsonic or supersonic, pure bomber.
3) Fighter-bomber project: definitely medium-range, possibly stealthy, supersonic, not a pure bomber.

Based on the rumors on this forum:
For 1), project status is active; a flying-wing, subsonic, and stealthy airframe has been confirmed out of XAC. There might be other competing airframes we don't yet know of.
For 2), project status is unknown; but according to Huitong,

was once part of the project.
For 3), project status is unknown but leaning toward dormant. If being pursued, it will probably be along the lines of an enlarged J-20 or a modified Flanker.

I'll offer an alternative

1) Strategic bomber project: definitely long range, definitely stealthy, definitely flying wing -- basically it's H-20 from XAC that the PLAAF are committed to
2) theater/medium stealthy supersonic bomber/fighter bomber project: project status unknown, PLA commitment unknown. Has been referred to as JH-XX, H-18, JH-X, H-X, H-1X and "platypus" over the years and recently. May have first been worked on by SAC (where the recent nose mock up pictures at SAC are partially representative of) and supposedly rejected by PLA, but now supposedly resurrected in some form at XAC.
3) fighter bomber project: does not exist, has been misinterpreted as a separate project from 2) when they are actually one and the same.


The theatre/medium stealthy supersonic bomber/fighter bomber and our current vague understanding of its role, as well as the many different designations that have been used for it due to lack of a single agreed upon designation, I think is the primary root of this issue and is causing different people to interpret new rumours in different ways.

Sorry, but that interpretation is placing upon the logical and semantic resources of both the English language and the Chinese language a heavier burden than they can reasonably be expected to bear; it's neither logical nor reasonable, considering the scope of our discussion, and considering, especially, that Fzgfzy has never made it clear, in so far as I can glean from his comments, whether the 'platypus' refers to a general project or one of the competing airframes within the said project.

I think the burden is not particularly heavy at all, if anything it is a sensible if not the most sensible interpretation of the information and hints that have been put out.

And yes, fzgfzy has never made it clear -- that is whey we are debating the issue of interpreting what his words actually mean.



For all we know, the

are nominees for the strategic bomber, and in which case, the Platypus is most definitely not the H-1X or JH-XX, both of which are speculated to be theater or medium-range in nature.

I don't know how anyone could interpret the platypus and the sting ray to be nominees for the strategic bomber, considering we are at a stage where the strategic bomber aka H-20 has already long been decided on the flying wing configuration and should likely make its maiden flight by 2020.




I suspect, Fzgfzy's separate replies, which were to different individuals, being grouped contiguously in the comment thread and both having in them the words "more beautiful" had caused Sinosoldier to conflate the identities of the designs and/or projects. This is why I have in my latest translation grouped the questions and replies in their chronological order so as to avoid such a conflation.

Yes, but the fact that they are both replies to comments under the same picture, and the actual contents of the replies makes it reasonable to interpret that his answers refer to the same aircraft as well.
Having both answers include the words "more beautiful" means it is entirely logical to think he is referring to the same aircraft.

I understand how you may interpret the comments and answers to possibly be referring to different aircraft, however I think my interpretation is far from unreasonable either.

[...] However, the article suggested "instead of relying on the carrier (bomber) to get close to target undetected, use long range stealthy cruise missiles to keep the bomber further away". This suggests that the Chinese bomber may be designed around a larger weapons bay than the B-2. [...]

Precisely the basis of my argument for 4500 km combat radius bomber. I acknowledge the practical and logistical logic of Blitzo’s suggested 6000 km radius and I agree. And, I’m very satisfied that Chinese planners are invested in the philosophy of placing greater emphasis on the capabilities of weapons delivery systems.
