Nice shots.
My favorite was a Kongo that I caught in the middle of a task force.
I was in an S-boat, very early war. Ran into a TF, and put at least one shot into the Kongo. She slowed down, and started falling behind, but she was still just behind the TF. I moved out to the limit of visual range, and tailed her for over 100 miles, until she fell far enough behind that I could close in without the trailing escort from the TF detecting me. I managed to get close enough to fire some Mk 10s into her.
The only thing I've managed to sink with exploding ships was myself, though.
