Magnetic Anomaly Detection - IJN ASW

[Rockin Robbins]

This makes a lot of sense. Unfortunately there are no magnetic fields associated with submarines in the game. The question is why this information is not general knowledge, and I think I know the answer.

In 1972 I worked with my father, who had worked on ASW projects until about 1970. One day he dropped a bombshell on me (undoubtedly violating his top secret clearance) that we knew the position of every submarine on earth from magnetic detection equipment in spy satellites.

If so, that would be a very good reason for the US government not to talk about any Japanese achievements in the same direction. If people are not even thinking in that direction they won't develop countermeasures for something they can't even imagine.

Amazing find! It will be interesting to see if modders can do something with it. I hope they keep its use VERY limited, as it would change everything about how you have to play the game.
