The HQ-19 is likely a complete version of the Russian S-400 Surface to Air Missile system.
Not only can the HQ's radar track 100 airborne targets, engage up to a dozen as far out as 250 miles, it is also effective for attacks on low-orbit satellites.
The system has three missile variations for targeting at different ranges and they can all be fitted into the same truck mounted canisters.
One thing prompting the recent American scramble to upgrade or replace the Patriot system is the fact that the S-400 is — allegedly, arguably, possibly, etc — a lot better.
