No, within 3 miles the message will be delivered regardless of the speed of the torpedo. This works for the player only. For AI platforms, the cruise speed of the torpedo has a value - the slower it is the quiet the torpedo, . But for the player, also bear in mind that even a quiet torpedo will be visible on the broadband display in 3 miles ranges.

PS: Scaling of sound profiles does not make it possible to make fine TIW dependence depend on torpedo noise. This gave poor results in the tests. So we chose the option with a fixed distance of 3 miles.
