I think the radar is as you say, never upgraded, but the tracker and target was definitely updated to support the new FAPDS ammunition, and compensate with algorithms for longer ranges.
I’m terms of the Gepard a2 not having stingers, it did IRL. Just not all where converted since the ozelot (and maybe other systems, but specifically the ozelot) was considered a cheaper alternative (in both production and maintenance)
The Gepard a2 did have upgrade packages to give it thermals (among other things), which would have renamed it Gepard 2. There was a few that where prototyped, but I cant find photo of it as a whole vehicle, but i did find a photo of (part of) the sensors upgrade package itself.
There was also a newer attempt, specifically using the PUMA IFVs gunner sight (EOTS II) integrated into the targeting computer. I found a photo of a converted test bed model, including a video of it live firing in tandem with a 2nd testbed model. There are a few dozen of these to exist to my knowledge.
Gepard with Puma IFV thermal and ranging sensors tied into the targeting computer.
1980-90 sensor upgrade package (not fully adopted due to cost of retrofitting)
I suppose that some of the other AA at that BR have similar issues, but not all, and generally the gepard is by far the weakest. I mean look at the American 10.0 AA. for .3 br higher (which at this br level, is nothing since you always get uptiered), you get a 25mm chain gun with 3/4th loaded HVAP belts, like 8 stingers (with 8 spare), better radar, and anti tank rockets that pen in excess of 290mm, not to mention its on a crazy fast wheeled platform, and is like 25% less high and overall smaller, and it gets full thermals.
That is a HUGE improvement, an that’s just once example. Sure some of the other SPAA dont have guns, but they do have better, longer range missiles0 both at higher and lower br, which at this br is WAY more useful when your fighting outer space camping JETs slinging precision munitions 8+km, nuking your team.
I cant find the original source, but i do remember hearing in a interview somewhere (pretty sure it was like a tank chats episode) that the gepard was able to track commercial drone at ranges of 100m out to about 2km. I don’t see why it is completely unable to deal with drones, when drones at that br can be a determiner of winning and loosening do the the amount of information they can give your team. It seems that they should have some method of being combated by AA. Id say id use the Stingers, but i can never get them to hit. You lock on, launch, and it flied directly at it, and within like the last 100m it veers off randomly every time like it was jammed, which it should not due given the AIM-92k missiles is IR/UV locked with anti jamming and flair countermeasures programed in to them. It should be able to hit a drone it locked on to flying in a straight, unmoving line easily, even if it is small. Soon as it locks on that should be it.
how are you doing the multi quote thing? I cant figure that out in this new forum format.
