China Claims It Can Make Stealth Fighters Even More Stealth
Key Point: Chinese scientists claim they have developed a new kind of material for making aircraft less detectable by radar.
But the development probably is not the breakthrough that some observers claim it is.
Prof. Luo Xiangang and colleagues at the Institute of Optics and Electronics, part of the Chinese Academy of Sciences in Chengdu, said they had created the first-ever mathematical model to precisely describe the behavior of electromagnetic waves when they “strike a piece of metal engraved with microscopic patterns,” according to South China Morning Post.
The newspaper cited a statement Luo’s team posted on the academy’s website on July 15, 2019.
“With their new model and breakthroughs in materials fabrication, they developed a membrane, known as a ‘metasurface,’ which can absorb radar waves in the widest spectrum yet reported,” South China Morning Post reported.
Luo’s claims and breathless comment on their implications do not constitute a major change in the way companies develop stealth warplanes or the military balance of power among operators of such aircraft.
That’s because the metasurface Luo is working on is just one example of type of metamaterial that has been the subject of research all over the world. It’s not terribly new. If and when it begins to appear in front-line aircraft, it could improve stealth qualities in a wide range of aircraft on both sides of the Pacific Ocean.
Metamaterials have been a popular research subject for more than a decade, Financial Times reported in 2018. “Metamaterials first captured the public imagination in 2006, when John Pendry of Imperial College published two papers showing how to create a Harry Potter-style invisibility cloak using the specially engineered materials.”
Lockheed Martin, which makes the U.S. military’s F-22 and F-35 stealth fighters, is a big investor in metamaterials. In 2017 the company partnered with a Canadian firm that produces lightweight metamaterials for solar-energy applications.
Metamaterials clearly are promising and, over time, could wind their way into various countries’ warplane-production. But they are not revolutionary.
South China Morning Post in a 2018 story gave voice to the skeptics. “There is debate in the research community about the value” of metamaterials under development by a research team at Southeast University in Nanjing, the newspaper explained.
“There is not a clear-cut definition of a metamaterial, so not everyone in the research community agrees with their claim,” a researcher with the Chinese Academy of Sciences said. “The consensus is that their product still has a lot of room for improvement.”

I have a million stealth fighters in the air flying all over the World right now. You can't see them, or detect them. Doesn't mean they aren't there.
China also claims to see through stealth tech yet they are trying their hardest to convince others it does work.
They absolutely can develop a more stealth plane, AS soon as they can get steal the technology from someone who discovers and manufactures the design.
I think the real story here is China is behind in research on meta materials. Now they have to do their research from scratch and just starting to realize how far they are behind. One way to find out how far they are behind is to publish a scientific paper and see the reaction.
An advice to Chinese Air force, it you want stealth for your fighters don't paint them bright yellow!

That’s like Steve Martin’s old routine, “How to Become a Millionaire: ‘First, get a million dollars”. For China, it’s “First, steal BETTER stealth technology”.
"China Claims It Can Make Stealth Fighters Even More Stealth" MmmHmm....And we've developed Hyperbolic Inter-Dimensional Mega-Thrusters and PU238 Explosive Space Modulators. Just ask Marvin.
Stolen technology , reverse engineering , patent stealing , China is great at what they do
A mathematical model. That is still a long way from working reality. Hyperbole by the article.
Yep. If you fly them into the ground like a dart they will be extremely stealthy.
It won't matter because it will still be Made in China, and we all know what that means: cheap and destined to break in record time!
Most people here are being condescending even though 98% of products in their homes are made in China.

Shouldnt this say: China claims it can make the stolen technology of stealth fighters even more stealth just by saying they can,
Did they steal our latest radar absorbing material?? Just saying we had had it already for years. But hey painting the aircraft YELLOW will sure help!

superpowers say this often, that x is better than whats out there... very often in China's case its simply reverse engineered military tech, or intermediary tech, that is simply not utilized by other superpowers - thats domestically produced.
We won't know what works until we engage in battle.. So China and Russia; keep claiming you have an edge over the US with your technologies. All will be hashed out in battle.
Aircraft Radar cannot detect any of these aircraft after they crash......
China's newest jets aren't even stealth by 5th generation aircraft standards. So yeah, of course they can make them "more stealth."
It'll make a great exhibit until they steal the technology for an engine to power it and the technology for the advanced radar, sensors, communications and the weapon systems to take to battle. Without that, it's just another airplane.
Its funny how every piece of new technology in China looks just like US developed equipment. To be honest, I feel sad for them......
Nothing new. Other materials have been used from rubber coatings in WWII submarines to special plating using amorphous alloys, all have some pros and cons. About 20 years ago worked on some of these and they were very good radar wave absorbents and or deflectors however cost, application and durability were always an issue.
Really China?? Well in that case, I have a stealth jet fighter park outside on my driveway! Oh..whats wrong, you cant see it?????? Well trust me its there!
NOTE:... ALL ''Stealth Fighters'', can be seen from space by the Hundreds of satellites place there for 'that' specific reason.
But why claim such a thing? I would keep it a secret if it was true. If it was false, I would bluff like this. UNLESS...
Of course they can. they will just wait until America researches and designs the system and then copy it or steal it out right.

Bold claim from a country that stole stealth technology, my guess is they weren't able to reach that result on their own.
By time China figures out stealth we will be using Quantum radars that can determine not only an aircraft, but exactly the size and shape
