Evidently, it has some interesting electrical advances, as well.
Remember on Star Trek when Kirk would say, “All power to forward shields”?
My understanding is that the Zumwalt puts out enough energy to power a small city and if it comes to a stop it can divert all that power to a railgun. If it had a railgun.
Additional tidbit: the Zumwalt is skippered by Capt Kirk. Seriously.
