Hey Zero, have you checked out Distant Stars mod? It has carrier-based electronic warfare fighters that can interfere with ships' functionality, and gunships that are powerful in their own right.
As for new ships, I doubt we'll see anything "new" until Sins 2 comes out, whenever that is, as it hasn't even been announced yet. Still, I've personally managed to replace a few stock ships with custom models here and there from other mods, for my own enjoyment.
