New Chinese Stealth Tactical Jet Breaks Cover

We breakdown the possibilities of what this new stealth aircraft could be and its potential mission. At this stage, it’s unclear if the new Chinese design is an advanced drone or yet another crewed combat jet.

Not that nonsense again!

holy shit... how any aircrafts do they have?
At this point the americans should go back to isolationism!

This was to be expected. US has over 5000 combat aircrafts in service. Plus another 5000 in reserves in "bone yard" and other places. Which means these will come into play in a long term war after attrition. Plus add others China has to factor in, EU, Japan, South Korea, India, Australia, etc.

China needs to grow her fleet of jets to 4000-5000 to manage so much competition. But China is smart. Instead of putting money into 4 or 4.5 gen jets like its competition has majority of, China is putting that money in the future combat jets. That way, they are eliminating the wide gap through better tech and bringing that gap down. For example, a J-20 or J-35 can easily bring down 4-6 4.5 gen jets. Now if you apply such ratio, China will reduce that gap through fielding 5th and 6th generation jets.

Recently, China conducted a test flight of its new sixth-generation fighter jet.
Although opinions vary online, most observers believe its silhouette aligns closely with the variable-sweep wing fighter patent design from Northwestern Polytechnical University (NPU). Based on the patent diagrams and publicly available test flight photos, I’ve drawn a ventral view diagram.

In this diagram:

• Referencing landing gear size
• Referencing side weapons bay dimensions
• Referencing cockpit length from patent drawings
• Referencing landing gear wheel diameter from patent drawings
  → Reasonable estimates: Fuselage length 19–20 meters, wingspan 15–21+ meters.

While inspired by the patent design, it’s not identical. Strict adherence to the patent (with its 3.3-meter side bay and two 4.5-meter main bays) would push total length/wingspan beyond 30 meters—approaching H-20 bomber scale. Yet this contradicts the slender single-wheel rear landing gear configuration, a key inconsistency. Personally, I estimate its max takeoff weight is comparable to the J-20, slightly smaller than Shenyang’s J-50. Its thrust-vectoring nozzles resemble those on the American YF-23 test aircraft.

Another major issue is the variable-sweep wing design: even at maximum sweep, the wingspan remains ~15 meters—wider than the J-15’s folded wings. This configuration virtually rules out wing folding, making carrier operations impossible. To achieve a target 9-meter folded span, the fuselage would shrink to ~11.4 meters—too small for meaningful weapons payload or combat radius, contradicting naval requirements. Thus, this aircraft is likely an Air Force variant.

Some speculate it might be a photoshopped image or drone, but I find this improbable. New weapons like the J-20, Type 05B , Type 055 destroyer, and Fujian carrier were all initially dismissed as "photoshopped" before being confirmed real. Moreover, numerous details on this aircraft indicate it’s not a dedicated drone.

The emergence of the third 6th generation Chinese plane



China seems to test the Delta designs without a tail with changes in the places of air entrances and suites, in search of the optimal balance between the superior hiding, efficiency in the fastest sound of sound, and the ability to control without vertical fins. The appearance of this new plane comes as a continuation of this approach, as China develops several experimental models, each testing a different aspect of the design equation, instead of being satisfied with one theoretical design that ranges towards production.

Modern fighters with superior disguise (VLO) focus on reducing interruptions in streamlined lines and reducing the opposite corners of the radar. The removal of vertical fins means getting rid of the two largest sources of radar waves, but that comes at the expense of stability and control capacity, especially when the attacks are high or during the landing of side winds. To overcome this, advanced Tirani control systems, extended sensors from the introduction to the tail, or the payment feature, or a mixture of these solutions.

And if China is now regularly operating experimental models faster than the sound without a tail, this reflects its confidence in its ability to solve control and stability problems, as well as radar and thermal fingerprint management around the air and exhaust entrances.

This is nonsense ... it is a testbed from the NPU but besides the similarity to the well-known patent NOTHING hints a stealthy VG-fighter! That's just hyped up BS!

Not a feasible design in modern day, too much dead weight and complexity for what on a sixth gen aircraft, so the only confirmed CCA drone was the one with Y9.

[The Equalizer]

It should be this.

The "variable-sweep-wing carrier-based aircraft" designed by Northwestern Polytechnical University.

If real, it looks like a useful design.
Allowing more lift during slow speed and landing on a aircraft.

Let's wait for the dust to settle. Judging from the current situation, the cost of J36 should be very high, and the probability of it being deployed in large quantities is not high. There is a possibility of developing two medium-sized sixth-generation aircraft as supplements.

The pic might be a bit altered but this thing is more likely to be a CCA drone; both cute orca and otter talked about this thing.

If true, this is defeintly some high end CCA drone.

Any idea which company make it?

Most likely a technical research projecht Demonstrator beim the NPU built by/at XAC

PS…. Seems they were faked again on the Basis of a J-36 image
