Guys, if you are launching SSMs from 20nm, they even don't get low to their cruise altitude before being engaged
. You know that after launch they climb few hunderds (if not 1k+) feets in the air and then dive low again. Reaching the 50ft altidute takes them quite long time. And they are detected in climb phase usually (by SPY), then if FC radar range is enaugh they would engage them immediately (in my tests I've launched SS-N-27s from well over 50nm (Sink the Nimitz mission), they were detected by SPY while climbing and engaged if FC radar could detect them. By the time SAM arrived, the SSM was again low under radar horizon but this didn't prevent SAM from hitting and destroying it.) The only thing that prevents this now is probably not too great FC radar range.
Try to launch your missiles from over 50nm. I know it's not very game-like scenario, but then you could observe true radars performance against true low flying targets, after gaining this inf you can return to game scenarios (so missiles launched from 20-30nm).
Also if you want to observe FC radar performance, try to disable SPY radar in database and rely on links for initial detection, then first DbgView report would be from FC radar.
Hmm it's interesting than in your tests ships waited untill target was ID hostile. I never observed that (or maybe I had only "detect" filter set in DbgView ?? :hmm: :hmm: )
