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

Because it is healthy for people to be able to practice self restraint and common sense. It is important for people to know when they are being silly.

Also, it is that ultimately the case that new information (when it does emerge) will be posted on this forum at a time when the thread may not be unlocked in time (mods are sometimes asleep or away).

It's hardly the first time this particular thread has gone off the rails. Far be it from me to tell you how to do your job, but if I was modding this thread I would've started handing out bans a long time ago.

Let's make this interesting. I am still of the opinion that the H-20, as we previously expected it, no longer exists and has been supplanted by the GJ-X (which I am inclined to call WH-X) and the J-36.
  • If the H-20 does appear in the near future (i.e. before Zhuhai 2026) in the form of a large manned VLO bomber, I will change my profile picture to that of a plain, unassuming Dorito chip for a year.
  • If the H-20 does not appear by Zhuhai 2026, or is of a completely different configuration/type from that of a flying wing bomber, I propose that this thread becomes permanently locked until further developments.
There is no role for a B-21 or B-2 sized bomber in the context of GJ-X and J-36. The only justification that I could muster is one of nuclear deterrence, where human redundancy is important, but such an aircraft would be built in very small numbers and unlikely to be a top priority for China's military.

Don’t try so hard. Usually doesn’t end well in this hobby.

Various posts deleted. Those whose posts I deleted should know why.

My advice is to try to avoid enjoying yourselves too much and being too imaginative.


I'm just going to start handing out spot six month warning bans going forwards if people try to get too fancy in this thread. Don't even try to be ironic or meta about the matter of fanciful H-20 ideas, just show some restraint.
There is no need to comment about people's inability to practice restraint if it means talking about another silly concept.

Remember to feel free to actively not post.



Two month ban to CMP and Antares545, and six month ban to Leibowtiz.
It's nothing personal, but we have to draw the line somewhere. For yourselves and others, for this thread and other flagship threads, my advice to avoid this is just "don't enjoy yourself too much"

A tender suspected to be related to the bomber, though some disagree.

Rough text extraction and translation by AI

Here’s what this tender is for (based on the screenshots):

Tender title: 铁鸟综合试验台共用设备、液压铁鸟设施、起落架铁鸟设施项目公告 (Iron Bird integrated test bench: shared equipment, hydraulic iron bird facility, landing gear iron bird facility)
Tender type: Domestic public tender (国内公开招标)
Region: Shaanxi, Xi’an, Yanliang District (陕西省西安市阎良区)
Issuer / buyer: Xi’an Aircraft Design and Research Institute (西安飞机设计研究所)** (name shown with some parts omitted on the page)
Tender number: ZKX#A018
Published: 2025-12-15
Bid deadline: 2026-01-08
Quantity: Listed as “#套” (a set, exact number not clearly shown)

### What it’s meant to do

The equipment supports “S-type” testing and ground simulation for aircraft systems, including:

* Hydraulic power system S-type component tests
* Full-aircraft ground simulation tests for the hydraulic system
* Landing gear retraction/extension control system S-type tests
* Wheel brake control system S-type tests
* Steering control system S-type tests
* Landing gear control system durability testing
It’s described as important supporting infrastructure for iron bird test environment construction, used to support pre-first-flight conclusions and post-first-flight design improvement, fault reproduction, and reliability growth.

### Main equipment included (project package)

1. Hydraulic pump drive unit plus electric pump noise reduction equipment
2. Hydraulic load simulation system plus hydraulic temperature control system
3. System pressure resistance test equipment
4. Hydraulic system “three-stage” purifier
5. Online contamination detector
6. Hydraulic oil water-content detector
7. Hydraulic landing gear test control and management system
8. Landing gear and hatch/door loading system
9. Landing gear power supply and electrical simulation system
10. Hydraulic test simulation system
11. Landing gear test simulation system
12. Hydraulic landing gear test measurement system

### Delivery and schedule

Delivery location: Yanliang, Xi’an, installation site at the buyer (西安飞机设计研究所安装现场)
Timeline (as shown): mentions milestones like completion within 2 months after contract takes effect, and delivery plus installation/commissioning within **8 months** after the order takes effect (some words are obscured, so treat these as the visible targets).

If you want, paste the “查看详情” page text (or another screenshot of the bidder qualification section) and I can summarize the bidder requirements and submission docs too.

Brief key points
Whatever this aircraft is, it has to wait for the completion of the "Iron Bird" in September this year, and the maiden flight should only be taken after test results from this "Iron Bird" is completed and will be used to ensure the maiden flight would be a success.

This points towards the date of the maiden flight would be either end of 2026 at the earliest, or in 2027.

Location of Yanliang may indicate this is military aircraft but if the Iron Bird is to be built in CFTE premises instead of Xi'an AVIC premises then we cannot discount civilian passenger plane like COMAC C929.

Also to be bear in mind that the Iron Bird in CFTE premises can also be military aircraft as well, since CFTE test aircraft from both military and civilian sector.

As to the "S" type, I cannot understand what is "S" type point to? If it is air intake ducting, then it would likely be military, but if points to something else, then I don't know.

An internally embedded (internal-bay) air-to-air missile and a carriage/launch control method thereof

Applicant: AVIC Xi’an Aircraft Design and Research Institute

This application belongs to the technical field of designing internally carried air-to-air missiles. It specifically relates to an internally embedded air-to-air missile and a corresponding carriage and launch control method. The missile includes a missile body, multiple slip rings, mid-body wings, and a drive motor. A circular positioning groove is provided on the outside of the midsection of the missile body, along with multiple arcuate grooves connected to the circular positioning groove. Multiple slip rings are fitted around the outer circumference of the missile body and positioned in the circular positioning groove, flush with the outer surface of the missile body. Each slip ring has an inner-side drive block, and each drive block extends inward through a corresponding arcuate groove into the interior of the missile body. Multiple mid-body wings are connected to the slip rings, and each mid-body wing spans across the slip rings along the missile’s axial direction. The drive motor is arranged inside the missile body and connected to the drive blocks, enabling it to rotate the slip rings and thereby rotate the mid-body wings. This allows the internally carried air-to-air missile to have a carriage state and a launch state.

Excerpt from a patent document of a split rudder design. The dimension is intentionally obscured, but allegedly, the length/width(?) of the split rudder (width: measured from the root to the edge) is over 2 meters.

For reference, the length x width of the split rudders on the B-2 is roughly 4.7-4.9 meters x 1.4-1.6 meters.
