There are at least 2 aircraft in the game now with radar guided turrets (B-52H and B-66). I have also heard the Tu-95M actually had a tail radar as well in a blister above the tail gunner’s window, but I haven’t been able to confirm this. It’s also not modeled in the game.
These turrets need to be properly implemented with radar tracking. This is important because radar guided turrets were effective out to about 1.5 kilometers, which is noticeably more than manual targeting. These turrets currently only have normal manual targeting, the same kind you can find on a B-17 for example. It’s not historically accurate, and it functions like a nerf since these defensive guns aren’t as effective as they really were.
The least we could do is implement a radar lead indicator that multiple modern jets and SPAA already have (see the included screenshot). This would require minimal work, and the devs could simply copy and paste the feature over to these turrets. I really don’t see why radar guided turrets continue to be completely ignored even with multiple aircraft having them now.
