A couple more
Kongo Battleship - any depth just below the aircraft, this will not sink it but will do serious damage, enough so that a secone torp in the aft section will bring it down. I have currently given up trying for a one shot kill on this guy as i have fired 100s of torps at different depths and locations and i just can't do it with one.
Shokaku Carrier - 5m depth in area between rear of the island and the engine exhausts. It will continue on for a bit sinking nose first before it rolls over.
