This is a question that has been bothering me lately...
In OTL, the Japanese battleship Yamato was sunk by around 11-15 torpedoes and 10-15+ bombs (give or take a few). The Musashi was sunk by around 18-22 torpedo hits and 20 bomb hits (give or take a few). Most people always seems to remark at how much damage these ships can take (by WWII standards).
If we used modern torpedoes, a Yamato-class battleship probably sinks in 1-4 torpedo hits. I'm pretty sure this has been covered before. What I have never seen discussed before is the MOST number of torpedoes needed to sink a Yamato-class battleship before it sinks. Assuming the Yamato could be placed at any latitude and duds are tracked, what anti-ship capable torpedo would perform the worst at sinking the Yamato in the following scenarios?:
Scenario One: any torpedo used operationally by the US during WWII.
Scenario Two: any torpedo used operationally during WWII.
Scenario Three: any torpedo used operationally post-1900.
Note: Yamato is sailing in the same condition as she was April 6, 1945 (Operation Ten-Go) sans escorts.
