Are US navel destroyers made of cheese?
I know this show is not exactly a beacon of realism, but a little mine/IED wiping out the engines and basically killing the ship? Well, I suppose they do crumple in real life as the recent two accidents have shown. Seriously, no proper battery backup for weapon systems? You've got to be kidding me.
Unless this is some kind of reverse propaganda to make the US appear weak.
Also, whoever is responsible for sound effects needs to be shot. Dubbing some shitty machine gun fire over the beastly CIWS. Criminal.
