Further examination of the video yields that USS Zumwalt is currently sporting 4 commercial type radars. Two on top the deckhouse forward and one on each aft corner of the hangar.
Hopefully they're only there for the trials and not when she is commissioned.
Those are Navigational radars.... any ships need Navigation radars. and those going to stay.
all the other radars have nothing to do with stealth... just a little (an added bonus), Just look at we do in Norway with our skjold class, it have conventional navigational radar, and 3D radar... but still manage to look smaller that a row-boat on the radar... and as we all know: "It's bloody dame frustrating to not be able to see the target that have just taken out a couple of you'r ships" that is Skjold class advantage.
Zumwalt is just the same... but on a much, much, much bigger platform.
