[UnderseaLcpl]

I searched for Yamato and that's alll the effort I'm putting into it.
I recently encountered two of these in the K.....sea...strait..whatever and after six torpedoes on ONE of them I failed to sink it before being driven off by a swarm of escorts and, somehow cruisers that seemed intent on running over me. My topedoes hit near the props and amidhsips and made four deleteriously prominent holes with little result. How do you sink these bastards?
Any comments, negative or otherwise are appreciated.
