USS Zumwalt cancelled it's main gun after the cost of one round zoomed from $60000 to 800000 after the ship purchase was dropped from 33 to 3. The purpose was precision long range land bombardment. The options now are to use a more conventional gun with the round at 60000 each , go to a rail gun, or stuff the ship full of missiles. I think they will go with missiles to fight off sea borne problems.
Everything is so complicated. And, I do mean everything.
