Back 30 years ago, China and Russia both also had academic research into hypersonic vehicles and designs, including releasing payloads.

Research papers mean next of eff all. It is step 0 in a 50 step process to flying and testing something. Step 0 in a 100 step process in putting something into service and being able to produce it in numbers for an acceptable cost.

The USA has made at least step 0 back in the 1970s if not earlier. Big whoop. Step 0 was taken by a fractionally powerful China back in the 1990s and earlier by the Soviets. They just don't put all those papers out in public like NASA has to, although in China's case they do reveal some of those less important/revealing papers years or decades later. Some of those allowed even end up being shared here. The US has flown a few hypersonic craft (not ballistic missile types but also not waveriders until the last decade) many decades ago. Saying the US has academic research in hypersonic separation is a big whole lot of nothing because China and Russia would both have that in spades back in the 1990s. At the moment, only China and Russia have flown waveriders and HGV weapons in service. The US has not yet put into service a waverider, much less several types like China has. The US also has not been able to fly an intercontinental ranged HGV (endoatmosphere and under own propulsion and/or shockwaves) which so far only China has.

As said before, Dr. Combs actually isn't terribly intelligent. He very often make simple logical errors. Perhaps this is why his level of research and knowledge of hypersonics is roughly equivalent to a below average phd in a second rate university in China. Just because NASA shows a fraction of 1% of something technical doesn't mean others copied it decades later in full by some miracle and used that to fill in the 99% gaps and then somehow overtake by some margin. These dogmatic morons simply cannot believe that Chinese people are actually smart, capable of working, capable of thinking, capable of refining things, capable of figuring things out. To them, Chinese people absolutely must copy and get the first step somewhere else in every matter. Despite Chinese people being the foundation and the source of propulsion for nearly half of America's computing and software industries.

Dr. Combs, you forget that China had their own academic research and papers on hypersonics many decades ago too. Since the Russians don't show their papers, does that mean they have none? Does that mean they don't have hypersonic craft? And one wonders why the Americans are lagging. Their academics are woke retards more than they are real engineers.

Edit political commentary above: The "woke" crew are anything but true lefties and basically the new useful idiots of the same old global elites. This group constantly work against the true left and made the western liberals and left a toothless shadow of its former self. All this by design. Now we have absolute bipartisan hatred of China and the polluting of western minds through incessant propaganda from three sides of the political spectrum, the true authoritarian left that remain are themselves too busy banging on about how good Marx is and how alright North Korea actually is. Total waste of time and intentionally so. May China refrain from politicising itself and falling into the pit of endless identity politics and emotional bs like Combs has - constant negative political commentary whenever anything to do with China. Hypersonics, developments, news etc are science... black and white, binary stuff. China has forged ahead of the US in hypersonics because it has done more work and better work between the 1990s and now. It had academic and theoretical research into this stuff since a bloke named Qian Xuesen.

It also has more hypersonic wind tunnels than the rest of the world put together. Better performing hypersonic wind tunnels and faster ones that run longer duration tests than anyone else in the world. China also has two exascale supercomputers to USA's zero. These things may not amount to much in terms of improving a nation's hypersonic programs but they sure do help.

Combs should focus on getting more funding for his real work and try to talk less about politics but in America, everything has become politicised.

I guess is to deter the increasingly belligerent americans, and to make absolutely clear to pro-independent forces inside taiwan that there is no way the americans is able to save them
That, plus when nations start to falter, they look for scapegoats, distractions for their populace and behave much less predictably. Lots of missiles are a good way for a potential target to say "trying something with us is a bad idea."

Lots of countries were working on suborbital rocket powered aircraft since WW2. The Nazis had the Silbervogel concept i.e. antipodal skip bomber by Eugen Sanger. The Soviets had the Keldysh bomber. Qian Xuesen as part of US Project Paperclip had access to the Nazi Silbervogel spaceplane research and did theoretical work on his own version of it. The US had the Aerospaceplane project post WW2. Much later in the late 1960s the Soviets had the Spiral program. The US had DynaSoar. So it is not like the research came out of nowhere.

A lot of the work done on high speed lifting bodies is applicable to the boost glide vehicle research.

Again, some people who can't bear to see their home team fall behind trying to bring up old papers and models to show "See, we have looked into this. No biggie." NASA may have been on it once upon a time. I'm pretty sure USSR/Russia had been on it too back then; the research papers now rotting under a leaking poorly funded lab somewhere (considering that they actually deployed a FOBS and low throw weight and duration of flight were a small concern for them).

But have these countries tested atleast a prototype?
The two papers he touts talks about ground tests in a wind tunnel (not the whole system but just the detaching component).

This from Chris Comb, who seem to be coping to the news so hard, he accuses (covertly) that China copied !
Show me a similar test to the Chinese one. Until then, dismissed. And the professor gets a D for the effort.
Learning on what Dr. Chris Combs and his team is working one may grasp why he reacted like that.

The Combs research group at UTSA explores high-speed aerodynamic and compressible flow phenomena using cutting-edge optical diagnostic experimental techniques, image processing, and data analysis. We make measurements in supersonic, hypersonic, and reacting flows with broad applications in aerospace and energy, with specific relevance to jet aircraft, air-breathing propulsion, and space access. Our primary research facility is the recently completed UTSA Mach 7 Ludwieg Tube. With experience partnering with NASA, the U.S. Air Force, the U.S. Navy, and DARPA, we are working to push the state-of-the-art in aerothermodynamics and make the next generation of high-speed systems a reality. Please contact Dr. Combs for additional information if you are interested in wind tunnel facility use.

Dr. Christopher Combs is the Dee Howard Endowed Assistant Professor in Aerodynamics in the UTSA Department of Mechanical Engineering. Prior to starting at UTSA, Dr. Combs worked as a Research Assistant Professor at The University of Tennessee Space Institute. His primary area of research interest is in the development and application of non-intrusive diagnostic techniques for compressible flows and he also has extensive experience in investigations of hypersonic boundary layer and SWBLI flow physics. Dr. Combs is active with AIAA, ASME, and APS and is a current member of the AIAA Aerodynamic Measurement Technology Technical Committee.

Some are saying depressed trajectory test (can see view of actual missile in flight in link). Depressed trajectory of an ICBM doesn't make much sense to me, so maybe a JL-3 test possibly?
The clip said:

"U.S. and Russia [sic] tested similar missiles during the cold war the technology is proven to be effective."

"Clearly Chinese military is pushing in every directions to develop advanced weaponries."
