Hypersonic cruise missiles like Zircon and DF-100 (and the US' HAWC project which is yet to be put into service unlike the Chinese and Russian HCMs mentioned out of the *known* projects), are rather lower tier stuff I have to say.

I wonder since when DF-100 is hypersonic? Isn't it only supersonic at most?

Could this breakthrough by Chinese scientists put hypersonic weapons on PLA aircraft carriers?​

  • Innovation would help lengthen lifespan of hypersonic weapons, which are required to last at least a decade

People’s Liberation Army researchers say China’s aircraft carriers will be able to use hypersonic weapons thanks to a breakthrough in logistics technology that simplifies and speeds up repair and maintenance of the weapons.

China’s air-launched hypersonic weapons, which have not been revealed to the public, have similarities to Russia’s Kinzhal missile, which can reach 10 times the speed of sound over a range of 1,000km (621 miles), the team wrote in a paper published in the domestic peer-reviewed journal Aero Weaponry on October 1.

But hypersonic weapons are more difficult to maintain or repair than traditional missiles, especially at sea. To date, there have been no reports of hypersonic technology being used on an aircraft carrier.

Xiao and his colleagues said their innovation for the quick repair and service of hypersonic weapons had passed stringent field tests conducted by the military in an aircraft carrier environment and other challenging combat settings.

The technology, which is not available in other countries, would serve “a large number of airborne missile equipment that are distributed widely in inland military bases, coastal airports and aircraft carriers in the far sea”, the team said.

The researchers reported that when cruising in the atmosphere at high speed, the surface temperature of a hypersonic weapon could rise up to several thousand degrees. During extreme flight conditions, advanced materials on some of the missile’s critical surface areas are absorbed or shielded against heat while allowing communication signals to go through.

But the hi-tech coating material was susceptible to damage during transport, storage or mounting to an aircraft, the team said.
“When the damaged part is exposed to the ocean humidity with salt and mould, failures such as moisture absorption, expansion, deformation, blistering, debonding or peeling can occur to the heat-resistant coating,” the researchers said.

In the past repairing these defects required a clean ground-based room with cutting-edge equipment, and an experienced service crew slowly and carefully ensuring there were no bumps or leaks on the finished surface.

Xiao’s team said they had developed a method using a unique sealing material to simplify the process. It required only a single worker to remove the damaged component, put in a replacement, filled the gaps with the sealing gel and smooth the surface of the hypersonic missile with a scraper.

In the field tests, including some conducted in “poor conditions” on aircraft carriers, the new method reduced the average service time to a tenth of the traditional approach, according to the researchers.

If they are supposed to be launched from carrier aircraft like J-15, i think they can't have similarities with Russia’s Kinzhal which is just an air-launched ballistic missile. US HACM should be a better equivalent.
These weapons are designed to be launched from aircraft, not a carrier. They can go after a wide range of high-value targets in the air or on the surface and can be used as anti-satellite weapon

They could increase the combat range of China’s carrier fleet to more than 2,500km – about the distance from the east of Taiwan to Guam – with ultra-fast air strikes that could penetrate most air defence systems

I wonder if said hypersonic missile can be fitted inside the internal bays of the upcoming J-35?

Since we would be seeing J-35s eventually replacing J-15s on Chinese carriers moving into the next decade.

According the description by the SCMP, it looks like the hypersonic missile is a multi-purpose weapon that can be used to target warplanes, warships, land objects and even satellites.

Once entering service, said missile could very well be a huge breakthrough moment for the PLAN. The PLAAF should consider adopting this kind of missile as well.

Of course, once the missile has been successfully introduced, the next goal would be to massively increase its production rate. The missile umbrella protecting China must be pushed as far away from the Chinese coastline as possible.

I would rather people pay more attention to direct quotation as Stephen Chen unfortunately has the bad habit of inserting his opinion on reporting Chinese research, and/or posting clickbait titles

Some examples

The test duration of 1000 seconds of the scramjet sounds like a substantial improvement over the previously published record of 600 seconds over two year ago.

These are likely two different scram jets by different teams. The recent test is by CASC 6th academy. The one you referred to is by CAS (China Academy of Science) mechanical institute.

It is possible that the CASC one is PATR (Precooling Air Turbo Rocket) which has been featured in many papers and patent by CASC. It has also been tested some years ago for mode transition. This time is likely testing the low speed regime.

I haven't find any paper on the CAS design, however the name in your report 范学军 (Fan Xuejun) is related to many precooling design. However it could be SABRE like rather than Air Turbo Rocket. The two are very different.

What I am trying to say is that we need to be careful not to mixing up progress of different programs because they are not necessarily benefiting one another.
