At least Senkanseiki isn't as tough as Senkansuiki (last boss from the previous 2 events). AP ammo actually could do good damage to her (with some luck of course).

Also AP ammo help you kill some enemies like Wo easier as well, so I think it's worth equipping it to the BB, at least for the BB in your main fleet.
