Chinese hypersonic weapon fired missile over South China Sea

China’s hypersonic weapon test in July included a technological advance that enabled it to fire a missile as it approached its target travelling at least five times the speed of sound — a capability no country has previously demonstrated.

Pentagon scientists were caught off guard by the advance, which allowed the hypersonic glide vehicle, a manoeuvrable spacecraft that can carry a nuclear warhead, to fire a separate missile mid-flight over the South China Sea, according to people familiar with the intelligence.

Experts at Darpa, the Pentagon’s advanced research agency, remain unsure how China overcame the constraints of physics by firing countermeasures from a vehicle travelling at hypersonic speeds, said the people familiar with details of the demonstration.

Military experts have been poring over data related to the test to understand how China mastered the technology. They are also debating the purpose of the projectile, which was fired by the hypersonic vehicle with no obvious target of its own, before plunging into the water.

Some Pentagon experts believe the projectile was an air-to-air missile. Others think it was a countermeasure to destroy missile defence systems so that they could not shoot down the hypersonic weapon during wartime.

Russia and the US have also pursued hypersonic weapons for years, but experts say the firing of countermeasures is the latest evidence that China’s efforts are significantly more advanced than either the Kremlin or the Pentagon……

Does the language used in these reports "fired a missile" rule out a kinetic energy powered (non fuelled) object being released from the mother vehicle?

I was wondering the same. Firing a missile implies the missile will be travelling even faster than the hypersonic carrier. Is this feasible, what kind of propulsion would be used? The missile would certainly be coming in hot!

There's much more to this story and interesting that information is leaking out.
Why aren't we seeing detail on the flight path, how it manouvered and where it and the `projectile' broke up - even only to the level of detail of `over the south west Pacific?'
It's not as if most of the capabilities of the `national technical means' that likely observed it aren't know about.
There's a lot of popular media hype about Chinese hypersonics - recent articles about standing oblique wave detonation engines etc.
But when you dig much deeper - they don't stack up.
FOB systems aren't new or difficult - some classes of MIRV have long been able to move up, down or cross range.
Extraordinary claims require extraordinary evidence.
ADDING: So now The Independent gives us a bit more detail. Apparently the terminal phase happened over the South China Sea.

"how China overcame the constraints of physics by firing countermeasures from a vehicle travelling at hypersonic speeds" Would firing it backwards overcome the constraints?

Unless you fire it at a speed if M5+ it will still end up going in the same direction as you. Any engagement of a hypersonic platform will, presumably be from the from quarter (otherwise it’s a hell of a tail chase), so counter measures need to be in front, not back.

Forget internal, presumably it would be carried externally as a stck and peel off using a solid state SCRAMjet capable of M10+. (X-43 type design but using a hypersonic launch platform rather than a rocket).
