Alright i have to say this but, I miss her wrist mounted torp launcher. while i get that "you hold guns with your hands" but a wrist mounted torp launcher on both hands wouldve been awesome.
Given what happened with Ashigara / Haguro, my guess is that they're already numbered when the navy ordered for new ships to be built so it doesn't matter which ship is built / launched first.
It makes sense since the ships are all built in different shipyards so one shipyard might be more free to start constructing new ship than the other at any particular time.
Edit: Pro tip, only ship order in Japanese wikipedia is to be trusted.
