It's mostly a sociopolitical thing imo. Big ship = we have something to boast about hahaha, we call it aircraft carrier and masturbate at night thinking about it how big of a ship we got and hope we could even gain some votes before elections thats always a plus side
It does not really make sense otherwise. We have like 7777 things to care before this, but navy and the goverment had huge and unrealistic dreams i dont really blame them, its not in our cultural to act rational and planned, we are mostly fanciful so now we got a big dick LHD and 2 huge ass LSTs. Our m48s cant wait to give it a go hahahah. Imagine you see this huge ass ship and then m48s popping out ahahahaha 10/10 would make day.
Jokes aside, I dont think when this ship planned to be build they thought our economy is gonna completely crash, we are gonna be ambargoed from all western countries on military sales and stuff, so there is that too. The plus side is at least we builded the ship succesfully in a fairly good time, dont forget it could always be worse. I think it is gonna be useful regardless even for civilian-peace time duties, if we had the ship during earthquake it could really help and also boost the morale sadly she was 2 months late.
