Normal pilots give next to nothing in terms of SD (no special class and "normal" bases). I couldnt tell you how much SD I have on my CV6 without restorers but even with 3 very nice 120 supports its probobly not more then 700ish.
I never really bothered to level any of my usn BB stuff that high since I do not use my CV6 and I have no desire to use overpowered content. I enjoy a challenge and have moved on to other nations for CV now for more exciting dogfights when I can find people that will actually fight and not run away.
