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

After discussion with Deino, we have agreed to reintegrate the previously separated posts back with the H-20 thread.

However, this is done predicated on a few key things.

1) The recent discussion about the idea of a "revised H-20" based on being able to internally carry a couple of JL-1 sized air launched hypersonic weapons (whether it's ALBM or HGV or HCM), is derived from some credible noise on the Chinese grapevine. The veracity and concrete nature of such noise is yet to be verified, however given past PLA watching trends and rumours we can integrate the idea of "carrying a couple of JL-1 sized weapons internally" as a characteristic for a "revised H-20" design

2) Discussion around a "super heavy" bomber like a 300ton monster, on the other hand, is somewhat beyond the pale. Let's remember that B-2 is 170 tons, and the idea of H-20 being nearly twice as heavy as B-2, while also being stealthy, is excessive and we would need highly credible sources to provide rumours for us to take it seriously. All of which is to say, that kind of "free wheeling rumour" is too much and if people start throwing around ideas like being supersonic capable for a B-2 weight class or greater aircraft, that also becomes a waste of everyone's time. You know who you are.

3) Excessive focus on "striking CONTUS" and WWIII nuclear exchange scenarios. While we all appreciate that any sort of strategic bomber will have nuclear strike and long range intercontinental conventional strike as a mission, and such requirements will drive the way in which the "revised H-20" design may look like to a degree, if people are unable to exercise restraint and discipline around how they talk about this topic then it just ends up consuming the H-20 thread.


I encourage people to utilize the following characteristics as some approximate starting guiderails for discussion, as of September 2025 based on current credible rumours:
- "Revised H-20 design" able to carry a couple of long unitary payloads (JL-1 sized) is okay
- "Revised H-20 design" being about B-2 or slightly greater (say, up to maximum of 180-200ton MTOW) in mass is probably within reason
- Key characteristics including stealth, highly networked, maximizing range within its weight class, is also reasonable

However, things which are probably too much and should be avoided:
- Idea of being a super large bomber (like 300ton MTOW)
- Supersonic (or hypesonic !!!) speeds is somewhat unlikely at present to consider and would need heavy justification and design compromise in other domains (such as weight class)
- Use of unconventional or unrealistic powerplant/engines (high bypass turbofans for super large bombers, or ramjet/scramjet for high speed ideas)

- Idea of using a uber large non-stealthy transport design as a "rapid dragon" concept or designing a "modern B-52/B-1/Tu-160" is also unrealistic (overall, the talk of any sort of bomber aircraft which lacks VLO in this day and age is somewhat useless and unrealistic for purposes of this thread)





I will keep the H-20 thread locked for another day or so, to give everyone a chance to read this post.
And then I will unlock the H-20 thread.

I generally dislike giving "guidelines" around these flagship military threads, but it seems some people just lack common sense and a lack of restraint.

I won't name names right now, but you know who you are.

鹰眼军视 mentioned today in response to GJ-X's emergence:

A certain type of manned stealth strategic bomber, now entering the final stage of its prototype phase, has as one of its key missions the undertaking of an air-based nuclear deterrence role. However, in human history there is no precedent for employing a new-generation unmanned stealth strategic strike aircraft to deliver nuclear weapons. Replacing manned stealth strategic bombers with unmanned stealth strategic strike aircraft faces multiple obstacles:

1. Issues of international morality and ethics

2. Ensuring the safety and reliability of nuclear deterrence

3. Questions of nuclear deterrence efficiency and strike costs

Therefore, at present there is no possibility for unmanned stealth strategic strike aircraft to perform nuclear deterrence missions. The manned stealth strategic bomber remains irreplaceable.

Large flying wing–configured manned aircraft no longer face technological obstacles.

The "Squidward" stuff are likely fluff so he doesn't get in trouble.

As for his credibility, I found this where he claimed Shenyang's 6th gen existed back in October

As I recall, we've had rumours that H20 was either cancelled or delayed for "re-imagining", I'm speculating that maybe PLAAF decided to go for an unmanned H-20 in the end, and this might be it. I'm not sure at this stage what advantages a crewed H-20 would have to justify the extra costs. Of course I have no special insight so this is just my speculation, but GJ-X does have a volume similar or greater than B-21 it seems, and is somewhat longer.

So probably the manned H-20 will turn up next month...

One of the core roles of the H20 would be nuclear strike, and that is not something you would ever want to trust to unmanned platforms to do.

Now, it’s entirely possible that the H20 has been re-imagined away from your traditional B2/21 flying wing stealth, since these UCAVs will now take on that role in the regional conventional strike domain.

That means that the H20 would most logically be re-optimised for intercontinental conventional and nuclear strike.

If that is the case, and especially given the embarrassment of riches China has demonstrated with its hypersonic missile programme, and great strides it is making with VEC and other next generation propulsion tech, it’s potentially possible that the re-imagined H20 goes the speed route instead of the stealth route.

If they can developed a manned bomber sized, intercontinental ranged hypersonic vehicle, that would truly be a paradigm shifting development. Such a design could very possibly be both fast and stealthy if they can take advantage of the plasma sheaf effect.

With China’s tech base, it almost makes more sense to go the speed route over the subsonic stealth route for next gen manned bombers.

I've moved your post to the H-20 thread from the UCAV thread because it's more relevant here.

I would also like to remind about the degree to which we are willing to entertain ideas like "supersonic stealth bombers" or applying something like VCEs or next generation propulsion to H-20.
See above, #4801

All of which is to say, let's not do that, unless there are actual credible rumours for such indicators.


We really do have a duty now to not freewheel and speculate too openly.

I am confused. First sentence mentions manned. But the sentence right after mentions unmanned. Which one is it?

Let's review Xi Yazhou's hints a few years ago, for example, he mentioned the need to carry a long-range air-launched intercontinental ballistic missile with a range of 8,000+ kilometers, which is exactly the same as the official data of the JL-1, hmmm ;)

And don't forget, Yankee also let slip around the parade that the "PAK-DA" is not far from a test flight.
Looking back, I think I was overly conservative. While the JL-1 was unveiled this year, it was actually a missile that was nearly on display in a 2019 military parade. The H-20 and its accompanying ALBM, as a 2030-ish project, certainly wouldn't compromise on the JL-1's size.

Assuming the 8,000-kilometer range specification remains unchanged (though its significance remains debatable), wouldn't it be a good idea to switch to a waverider glide vehicle? The addition of a glide phase could reduce the size of the booster, as seen in the DF-16 and DF-17.

Furthermore, what about a waverider glide vehicle and scramjet engine? PLA has even developed an extremely miniaturized, submarine-launched YJ-19. Would developing an air-launched scramjet version for the H-20 be that difficult? As we have seen with the Navy's YJ series, the YJ-20 is just the starting point, there is no reason to believe that the JL series will also stay at the biconical.

First sentence refers to H-20.
Second sentence refers to the idea/concept of GJ-X being used for delivering nuclear weapons, and saying there is "no precedent" for it and therefore unlikely to be one of GJ-X's roles.

That's how I interpret it.
