Anything pass lockon range means nothing as your turrets can’t track or target pass it.
An Apoc with targeting max to 300km and only attack to 300km, even if its tachyon turrets optinal range is 268km and the first falloff range goes pass the 300km mark.
Caps can be pushes to 350km targeting, but still have the same issues of that it, weapon can got farther, but with no targeting they are useless pass 350km.
As notes above Starbase and Structures can target out to 500km and most large defense weapons can get up there. This can make them deadly, we tested a POS on the test server and even Titans could avoid its turrets before it was capable of firing. 150km of being attack without being able to fire back can be un-nerving even for a titan pilot.
