All good advice! And yes, once it gets within a certain range, the layer doesn't really "exist" anymore (the critical angle), it will still distort the absolute direction of the sound relative to vertical, as shown in this picture, but not necessarily the bearing of it. In my experience, its about 1.5 to 2 nautical miles (3000 - 4000 yards/meters)
(they show flashlights here but it's the same idea for sound, both are wave propagation)
The reason you're getting the torpedo in the water (TIW) is because torpedoes are launched with pressurized air (aka loud!). There may be some launching methods that currently exist or are in development that use magnetic force like a rail gun or roller coaster but none of that in stock Dangerous Waters, at least. As mentioned, there is no swim out option, even for UUVs, which should swim out.
