As we’ve seen modern ships are extremely vulnerable to fire. Read “Last stand of the tin can sailors” and see how much punishment a WWII destroyer could take and still fight. Modern ships with aluminum super structures and such can’t survive a single 8” hit much less several. While speed is important we are talking about a few knots difference in the 30knot zone. In reality this is a snail’s pace in the face of modern guided weaponry.
A WWII battleship’s bridge armor would resist a conventional cruise or surface gun seeing that the largest guns are 5” for the most part. I’m not suggesting we build battleships but it might be wiser to sacrifice a knot or three for a superstructure that won’t melt like butter. The other thing not generally discussed is the vulnerability of the electronics. A mechanical fire control computer might have less capability but it won’t go offline at the first sneeze.
That’s “anti ship missile” not “cruise”.
