The nature of warfare has changed significantly since the 1930s, and the ships being built today are a reflection of that. When ships were fought in a line of battle things like armor mattered. Ranges of thousands of yards made a tactical difference for side armor and deck armor penetration. In the era of over-the-horizon weaponry, detection and weapons range make the difference. There is no armor plate to protect AEGIS radar arrays and all of the sensitive electronics that modern weapons systems rely on. The premise is that it is far better to kill the archer than try to intercept the arrows. Much of modern missile combat can be explained by the work of Captain Wayne Hughes and his salvo combat model (https://en.wikipedia.org/wiki/Salvo_combat_model).
I don’t know how much punishment anyone expects a ship to absorb in a collision with a vessel 12 times her displacement. Battleship armor couldn’t have protected against tonnage like that.
