They needed nine corossive torpedos to sink Hyuuga and obviously they couldn't use Gravitational cannon simply cause submarines doesn't have one. That one they currently have used to be Hyuugas before she were befriended (and due her being sunk she doesn't need it anymore)
Anyway that mecha freak had quite fun in last chapter. I Guess I will give her third place after Takao and Kongou
