Nowadays they determine ship class and speed by listening to the propellers only. Knowing target speed AND bearing makes it easy to dertermine range and course. Perhaps some of you know this technique from SSN688(I) Hunterkiller?

I have been trying to work something out based on the few facts provided to you by your sonarman:

1) Bearing
2) Speed: fast, medium or slow (approximately 12+, 9, 6)
3) Target moving away or closing

Problem is, this is a time consuming method. Just as you are beginning to get a clue, what is going on up there, your target is already anchoring in Tokyo Bay. Not to mention the frustrations coming with the target simply altering its course and makes you feel like an idiot.
