Torpedo sound levels and enemy detection

Standard heavyweight torpedo's are not stealth weapons. They all radiate a lot of broadband noise due to their design. High speed coupled with small propulsion mechanics makes this assured. It is just basic physics.

Anytime a weapon gets to the enable point and goes active, there is NO stealth evolved. You are radiating a high power sonic pulse to get an adequate return for the weapon to perform.

Most modern submarine forces have some type of dedicated active intercept receiver, or modes of operation tuned to the expected weapon frequencies of adversary. Anything less is just stupid....

So yes, when the weapon lights off, he's going to hear it....even if he is outside of the weapons range. I find the Russians expected alertment range against a MK-48 (pre-enable or post-enable) reasonable.

The surface ships on the other hand is highly exaggerated. Especially when running over 20kts.
