My latest attempt at specifying the "super fast battlecruiser"

I was successful at specifying and doing the calculations for my "Super Fast Battlecruiser" design, using the current state of my warship general design program. This was the picture of what it looked like: . This ship has an armament of 4-17in/45 and 16-4in/50 guns. This is some of what my program produced:
