Only hits count. A "broadside" of 5" shells that only hits water is a lot less useful than a smaller caliber auto-cannon that hits the target. That said, I too am disturbed by the lack of armament on these things. 2200 t and all they can come up with is one 57mm? Really? There's plenty of room for more, even considering the space taken up by the helo deck.

As for hull size, private rooms for the women sailors takes up space.

Arleigh Burke was laid down in 1988.

That's about the range of a pre-dreadnaught battleship.

The increase in hull size from pre-Dreadnaught to Iowa or Yamato was accompanied by a corresponding increase in gun size, with little change in the fundamental technology of the guns or sighting mechanism until the very end. We now have ships of the same tonnage but totally different armament and mission.

Well it appears there are some vertical launcher cells behind the gun so ... missiles!

Well, consider how much more tonnage and cost would be required by a ship with roughly the equipment/armament fit but twice the speed (hint: ask Lockheed Martin)

If you are referring to the ship in the first picture, it’s being operated as an OPV, so armament will be limited to what works best for patrol missions.
