There's only one critical problem with this whole "OMG ship waifus are dying!" situation.
It is not possible to kill a shipgirl in Pearl Harbour so long as a significant chunk of hull is intact.
OTL Arizona could, in theory, have been repaired. It was a write-off because it wasn't worth fixing.
They even had to build a memorial over it to not have the ghostly ship-girl walking around twiddling her thumbs scaring tourists who aren't in on the secret.
Capsized or sunk ships can IN THEORY be righted and refloated until they sink far enough to implode. PH doesn't allow for that end... so ship-girls are next to unkillable when in harbour.
Implications abound
This.
I mean, heck,
California actually did sink! Sure it took her
3 days, but she did sink until only her superstructure was above water. They raised her on the 25th of March, 42, and had her underway under her own power on June 7th.
That said, I wouldn't be surprised if any ship that had manifested as a shipgirl just actively refuses to float
no matter what. Or if raising the ship binds the shipgirl to the hull, only now they are physically able to interact with the crew even though they can't leave the hull until it sinks or is scrapped.
Either way I don't see them raising
Utah for the same reasons they didn't in reality, she's a training ship and severely outdated. Heck she doesn't even have her main guns anymore.
I wonder how fast the war would just
end if Abyssals suddenly arrived?
What concerns me the most, though, is this: Shipgirls appear to be summoning. That's great, right? Other than the implications for the war, I mean.
Yeah... maybe not so much. That means the wall, barrier, or whatever it is that keeps the spirits of the ships out until the Abyssals show up
is weak enough to allow them to manifest. This means that Abyssals
may be, or soon will be, present.
