The ship will either get the ammo (eventually), or switch over to a rail gun. Either way the ship is a technological test-bed now that the rest of the vessels will never be built. It’s a modern USS Langley.
I’m not saying that I agree with what is being done here. But now it’s making the best from a series of bad decisions.
Thing is, Langley was never used in a position where it could face combat. We’re deploying Zumwalt *already*.
