Unless, of course, it isn't, because the ADS is not compatible with that new stuff being added, in which case, its removal was necessary.
Exactly, to my way of thinking it is when my country went from analogue TV to digital TV, suddenly all the old TV's wouldn't work without a converter.
So just think of the new tools as digital, our ships have had the necessary upgrades to be able to use them, but the old analogue ADS just won't work with the new technology.
