I mean... how else do you know where to position yourself for a clean shot? Up until now, I've been taking a SWAG at it and often i find myself spending way too much time chasing a target that turns out to be outrunning me. Very frustrating. (BTW, SWAG means "super wild ass guess.")
THEREFORE, looking at your 1:37m formula, let me ask if this would also work? Watching the target for 3:14m would tell us the speed without having to multiply by two - right? Or should I STILL multiply by two? So, if a target travels 1200 yards in 3 minutes and 14 seconds, he's going 12 knots. Am I correct on this? If I am correct, this means that, if I am underwater and my target is crossing my bow at 12 knots, I might just as well let him go and wait for a juicier target because I likely cannot put on enough speed to get ahead for a clean shot. In one game, I was chasing down a couple of potential targets without this knowledge. I found myself in an absolutely perfect targeting position .... FOR THEM TO SHOOT ME! It turned out to be a pair of destroyers and I did not survive. This was also before I learned to recognize between black sonar echos and blue sonar echos. You learn real fast when you're constantly getting killed.  I think I should still multiply by two. 250 yards in 1:37 is the same is 500 yards in 3:14. Jeeze I really am NOT good with math. |
Those are the formulas for speed.
(Distance traveled in 3:14) x 10
1:37 x 20
From very close range I often just go for like 38s and do X40. As a rule of thumb. The longer you wait. The more precise it is.
Also when attacking convoy. BE VERY careful of your distance and speed. Escort can hear you way before they actually see you. Wich is why the most common strategy is to get ahead of them then wait close to their estimated course.
Don't try to catch up on them. Plan an interception course.
