ok, that's why I thought. I do the same, 2 FC, 2 sensors. Sometime 3 on the bigger ships. Now I did not went above 7000t (CL), but I have shipyards ready for 18.000 (CA), 30.000 (BC), 60.000 (BB), 120.000 (CV). I just need to stabilize the techs to something not deprecating too fast, and then find a specific rule of engagements for each class.
