TorpX, "In the literature I've read, Captains were taught to use a track angle referred to as the "optimum track angle""

While this is true because of the malfunctions of the torpedoes the optimum became the "never use". It was only a temporary fix until the string of errors had been tracked down and resolved but skippers were told not to use the textbook firing procedures when it came to optimum track angles.

In the diagrams I have listed what I labeled as "worst" was actually what they recommended but Admiral Lockwood changed that because of the better success with the large obtuse angles. Glancing hits caused less duds when using the contact detonators. This fault was due to the guide rails and firing pins being crushed upon impact at optimum angles.
