[TorpX]

I have never had a circular running torpedo. Now I wonder if I ever had one but just did not know it.

I was more or less thinking this.

Do they travel in a perfect circle, or do they just loop around generally? If they travel in a precise circle and are "preordained" to hit you, that is bad news.

Likewise, it is not helpful that one cannot detail the sound operator to track the torps as they are fired. Diving deep whenever one makes an attack, just to avoid a rare circle-runner, seems too extreme.
