NEDS - Not Enough Deck Space for all those guns and torpedos;
Bambi must DIE!

P3D

Get another half knots speed (equal to the KKs). And a third 7.5" turret. Make the secondaries 4".

Below 40 degrees, there is no law. Below 50 degrees, there is no God. sailor's maxim on weather in the Southern seas

Ahoj!
In heavier seas this ship will be faster than the KKs.
You think 16 (I doubt if I can find deckspace for more) four inch guns would be better against 500-1000 torpedo boats/destroyers?

BTW - putting the 6 inchers in casemattes saves me several hundered tons ...
