Impressive!
Great work!
I will build on your findings. Assuming the warhead is an inert slug made of Tungsten, and that it is travelling at Mach 10. The kinetic energy this warhead will carry is around 1/2 x 200 x 33300², which is around 1 GJ.
Assuming an impact time of 1 millisecond, this warhead can generate about 660 million newtons of force.
This can easily generate enough force to buckle even the strongest steel. For example, HY-100 steel only has a yield strength of 930MPa, and a cone shaped projectile can easily exceed that twice over.
In short, an impact from an inert warhead can penetrate the flight deck completely. Depending on where the missile hits, the arresting gear and catapults can be disabled. More importantly, since the warhead is heated up during reentry, the glowing hot warhead may hit the hanger and set fire to any planes or fuel dumps in the area. IMO, we are looking at flight deck damage and fires at the minimum. Hard to say if it is enough to sink the carrier, but certainly enough to put it out of action for a while.
Terminal velocity probably won’t be Mach 10.

Surely this is not how they are deployed. This GARA company seems to be a private one? The state owned/ PLA backed HGV is the one that released a payload as referenced in the FT article, unlikely to be some random private company that uses such a model. I understand it's only trying to show carrying capability but that is certainly not a good representation of how a carrier HGV deploys submunition. The centre of gravity would be changed too suddenly for flight controls to compensate, particularly at those speeds.
I suspect GARA here is taking advantage of what the PLA/ state owned enterprise was able to perform.
They won't let the actual thing be shown. If it is indeed GARA's HGV that was tested deploying a submunition, this probably isn't an accurate representation of the HGV they used and certainly isn't how it is loaded. That much would be obvious.

It could be a real design for this specific purpose. The carrier only use its HGV feature for range and cruise altitude, the carrier does not need accuracy but a general area. The accuracy is achieve by the submunitions. At the far end of the cruise range, the speed could be very low (the further it goes the lower the terminal velocity), as low as subsonic.
HGV like DF-17 relies on kinetic energy of high precision single warhead at impact. While this GDF-600 would be using HGV for range and altitude only.
The translations says the HGV… Disintegrates. I don’t believe the submunitions are “deployed”, I believe they simply survive the disintegration of their carrier, and then go about their business.
