Asdic "only"

John Pancoast · 02-09-21, 09:38 AM

In the hope of making the escorts use only their asdic for sub searching per historical info., I edited out the hydrophone nodes of their .sns files.
In my understanding there is still some hydrophone code in the .exe file, if so I guess one can never completely get rid of them.
But interesting tests so far; some good, some not so much. Going to experiment with the sonar sim.cfg setting a bit too.

Let us know the results of your experiences!

May be getting better. To early to say yet.
Of course, its not that they didn't have/use hydrophones. Just that the SH3 method of "phones contact first, then asdic" is completely wrong as asdic was constantly banging away irl.
If anything it was "asdic first, phones to assist if needed" I believe.

Exactly. Hydrophones were used when they lost ASDIC contact (U-Boat fully underneath)

Still using their phones too much and asdic to little. Better but not good enough.
Oh well at least now I know.

Hi John,

I made a small test by limiting the hydrophone sensor depth to values > -30m, then dove to -50m and approached an escort. As I expected the escort detected me with ASDIC without any previous hydrophone detection.

I'm pretty convinced that the escorts use both sensors all the time. Just because one does not hear the pinging, one should not conclude that the escorts don't use ASDIC.

The problem with removing the hydrophone is that it gives you an unrealistic advantage because in this case you can escape ASDIC much easier by running full-speed ahead without any risk. Therefore I think you need both sensors: hydrophone to keep you from running high rpms and ASDIC to keep you from becoming 'invisible' by 'Schleichfahrt'.

Best, LGN1

PS: The real problem is that in SH3 the hydrophone also provides your depth to the escort. Since this was not possible in real-life, escorts had to use ASDIC for hunting. However, it's my understanding that they also listened all the time to prevent the u-boat from running away at high speeds.
