A couple of notes now I am designing small ships in my current campaign.
I have added new modifiers to fire controls, allowing 1.5x range / 1.5x size and 1.5x tracking speed / 1.5x size, although the fire control itself will also be rounded up to the nearest whole number. This new modifier is because one HS can be important when designing the new small craft and it allows a 3HS system with double range and 1.5x tracking speed, or vice versa.
One issue that concerned me a little regarding the small systems necessary for gunboats/LACs/corvettes (or whatever we end up calling them
