TL;DR: G6-HVM is a SAM based on G6 chassis with 25km Search radar, combined radar/eo tracker and 12km 40g missiles.
Hello, and welcome to my suggestion. As most of you are probably aware, G6 is a present in game SPG who has an ability to use its proximity shells to destroy planes. But that is not always enough, and here comes this specialized version.
History
The development of G6-HVM starts with ZA-HVM programme. ZA-HVM along with ZA-35, started in 1983. The main SPAAs of South Africa then were Ystervark and Cactus. While these systems were doing their jobs just fine, they were starting to show their age in comparison with systems used by other countries and the aircraft they were supposed to counter. That resulted in a competition where multiple foreign systems were studied, but South Africa decided not to buy someone else’s system and decided to make its own. As works on the ZA programme were commencing, in 1992 the proposition for increasing the amount of missiles from 4 to 8 on a bigger chassis was presented and accepted. T-72 and G6 were presented as possible candidates. Ultimately, G6 was chosen as the chassis and its development began. A single prototype was completed, but reduction in funding ultimately killed the project.
G6 development started in 1976. Up until that point SADF was still using mostly WW2 artillery, and need for something more powerful and modern arose. 1981 marks completion of the first prototype, and as soon as 1988 the serial production started. G6 is in service of SADF up to this day.
Now its time to talk about the specifications.

Missile envelope
This sums up this suggestion. This vehicle has decent mobility, its missiles put it on an equal footing with the current top SAM systems, it’s strong radar will give it great situational awareness and tracker that can operate silently would make it a force to be reckoned with.
