I'm neither surface warfare, nor any combat arms, but in my opinion it doesn't fit into our current concept of distributed maritime operations (DMO). And if we decide to build these, how many can we build? It certainly would be nice to have a large ship that can provide enhanced air defenses, offensive capability with both missiles and rail guns, and have advanced sensors on board. But is one big ship better than 3 destroyers? Not only in terms of offensive capability, but in terms of maintenance, parts sharing, ability to take crew members from one ship and put them on another without much retraining? Not sure. But 3 destroyers might better fit into a DMO strategy that would make it harder for the enemy to amass forces or freely move about, and help provide cover for Marines as they hop along islands.
I also believe that the Navy is still trying to figure out how to fight the next war and isn't entirely sure what tools it needs. Combined with the military industrial complex, and congressional corruption, it wouldn't surprise me if we go down a path of building yet another failed ship program.
