"Torpedo has acquired!"

Reading Clancy's SSN (one of his weaker books so far to be honest), and remembering movies and other books on the topic, I noticed this call-out and wonder what's behind it.
In DW we do not have this message, nor do we know if a fish acquired unless we check the weapons station or map screen for irregular movement of our fish ourselves.

So I wonder, how does it work in real life, how do sonar or weapon crews know? I'd imagine that a wire-guided ADCAP sure sends some info back to his host which may really say it has found a target or not.

Wouldn't it be, theoretically, possible in DW to alter the torpedo doctrine, having them "send a message" that they locked on to something?

I think that would be awesome!

You can send torpedo with 5 kts less than max. If torpedo is acquired - speed will increase to max. When torpedo loose track - speed will back to searching value.

That's a nice work-around indeed, but also requires manually checking, constantly, in a situation where I'd rather take other actions

Before hit you should always track on map own torpedo and mark on map ("enter" key):
- when target is acquired
- when torpedo loses track (because of decoys)
- exact hit point (sometimes you need use 2 torpedoes)

This things have very high priority for experienced player.
For me higher priority have only torpedo evasion.

It is obvious you speak from multi-player experience.
I usually stick to sp, because I am more interested in whole scenarios and even campaigns, rather than single combat situations. Good advice though, I never did manage my fish that detailed, I will experiment with it.

Anyways, my point was not "how to know", it Was "is it possible to bring the mentioned feature into the game".

Maybe it is possible - similar for UUV or Korund mobile device.
In other hand i think wireguided torpedoes shouldn't be controlable in all range like it is now. That means, feedback also should be only in close range to own submarine.
