According to unconfirmed rumors, this is a new variant of the HQ-22 or FK-3 SAM system, which was displayed at the Zhuhai Airshow in 2021.

Note that this system seems to be vertically-launched as opposed to the slant-launch mechanism of the older HQ-22 version.

What is the main advantage of vertically-launched to slant-launched ?

What other improvements of this HQ-22 version to the old one? range and radar maybe?

Is it true that fk-3 have speed mach 8? Wikipedia say that

No way HQ-22 has speed of mach 8. HQ-22 is a medium to long range SAM missile. You might be confusing it with China's ABM/BMD missiles HQ-19/26/29. BMD missiles may go well into hypersonic range especially exoatmospheric ones. Mach 8 for those missiles are possible.

HQ-22's range sits somewhere between HQ-9 and HQ-16. It is a development from the KS-1 or HQ-12 missiles that changed designs and incorporated new radars and vehicles - C4ISR ECM EW etc.

Cold launch enables vertical launch. Vertical launch is considered superior in SAMs with the exception of short-range SAMs. It deals with multi-angle or surprise attacks better since the launch direction is unbiased towards all directions. Vertical launch is also better in confined spaces like cities, hills, etc... There is no chance of a missile running into a building just after the launch. For short range SAMs, it is different. Such missiles have flight times measured in seconds and usually engage in low flying things. For those, turreted launchers like the SeaRAM, Pantsir, HQ-10 are better because turreted launchers enable them to directly speed towards the target without making any maneuvers.

When it comes to a lot of things military missile ranges and speeds etc, wikipedia information is at best, accurate to publicly known brochure data. In many cases where such data isn't available, it doesn't provide one or it provides a questionable one based on questionable sources.

Mach 8 is almost certainly wrong. All SAMs (that aren't ABM missiles like HQ-26/29 etc) are well below hypersonic range speed (mach 5 and above). The faster SAMs can accelerate to a top speed around Mach 3.5. This would be considered a very fast SAM. Typically this is Mach 2 to Mach 3. This is also its top speed when the rocket motor's fuel is exhausted and the missile no longer propelled. Can you imagine a Mach 8 SAM achieving Mach 8 within the atmosphere? Especially a medium to long range missile, not even a multistage extremely long range missile. If the Mach 8 edit is accurate, it would require some groundbreaking new rocket/propulsion technology.

So yeah. Wikipedia is almost certainly wrong about Mach 8 here. Wiki is like maybe a go to initial get to know a topic kind of source.
