Well I don't see any mention of Extended Range Munitions yet ( which give a lot more than an extra few km ) - then again it's obvious to anyone that a ship with one type of every system just requires an unlucky hit or malfunction to get knobbled - see the Falklands War & HMS Coventry + others; of course the designers / specifying politicians weren't aboard in combat.
I don't find any surprise in Daring not being fully operational, I've never seen a complex military system which is !
