If you let me comment the design nicely: Oh god, no!
Well, at least that was my first reaction upon seeing it equipped with a ram. And, it still is for that ram. The other systems look pretty nice - they can complement the cruisers nicely. But the ramming tonnage will mostly be useless - ramming may be useful against unarmoured enemy ships (note the may, that's a pretty big may), but will therefore need to close within close range. And, looking at our own models, it would be engaged by 40mm guns and 15mm machine guns long before closing - even when the main guns are occupied.
In facts Rams were placed on many pre WW1 era vessels of all sizes it was decided that it is impractical mostly because combat went to greater ranges, not because you can't sink enemy with
There are many ship that were sunk\badly damaged in friendly, low speed, collisions.
You badly underestimate size of a hole that ramming can do
Ships are hard to stop, even if you blow half of it, inertia will do the job. Also, Ships are bad at dodging
With armored nose machineguns will not be that effective against narrow ship aproaching that way. Remember that deck is mostly empty as there are no guns to man. Same goes for 40mm... 80mm are problem, but they still need to hit
If we gonna use rocket torpedoes, we may as well use the ram. There are almost no difference between 1km and zero in naval battle... Ship needs a minute at most to cover that distance... So, going close enough to be able to use rockets is almost as suicidical as ramming, in no way the ship can retreat after getting so close to cruisers, at least let it ram in effective way
As it was pointed, ram designed in a proper way helps hydronymamics
Many submarines were sunk by intentional ramming during WW2
This ship needs nose armor anyway, why not ram with it?
