I'm beginning to understand what you're saying...i think.

What are the advantages of a bulbous bow on a frigate or destroyer? It is
an excellent place to put active and passive sonar gear.

But would be a bad place if trying to run over a submarine. Which was a
common tactic. As the early subs surfaced and used cannon fire to sink
ships. Later, they got rid of the deck gun and used torpedoes as the lack
of a deck gun made the sub much faster underwater. The 2 design criteria of
the early and also later battleships were they had to fit under the Brooklyn
Bridge and through the Panama Canal. I fish near the Iowa at times and it
is amazing how low to the water the deck is midships.
