How the hell did this happen??

CaptainNemo12 · 04-02-10, 01:38 PM

I was approaching a convoy head on at periscope depth at ahead slow, silent running, with the leading frigate approaching at about 8000m - 9000m off my bow. Decided to dive to 40m and ordered all engines stop. At this point the frigate is about 20 degrees off my starboard bow.

After a few minutes, my boat was dead in the water and not making a sound. As I watched through the external camera, the leading frigate continued on its course for another 5 mins as if it no one was there. Suddenly, at about a 1000m away from my U-boat, the damn thing veered off course and started pinging away at me!

How this this happen? I thought that warships only started pinging after they had detected propeller noises? How could they detect an object underwater that is not making a single sound?

I'm playing GWX 3 and this is not the first time this had happened, I once tried to pass below the keel of a merchant at about 50m underwater when the merchant somehow detected me (underwater!) and turned to avoid...

Any ideas?

1) what date?
2) escorts in late war "ping" constantly
3) 1,000m is very close (should've been 2-2,500m)

and fourth and most important:

sink em all!

In GWX3.0 even?

Currently in 1940, any other ideas? Could this be to due to surface units having "underwater" sensor data in GWX?

Happened to me too at very early 40 and not only to me. There is other threads complaining that DD's have "psychic powers". Some messages claimed that this is known glitch that when sub presents excellent sonar target cause angle and DD is near by it does start to ping.

So, maybe they really have "psychic" powers.

Some peoples told that DD's that were mess with before stays alerted state and may ping randomly.

Who knows?

In GWX the escort is nearly always in a passive state/mode.

If their sensors alert them to your presence in the area they then go into active/pinging mode.

Thanks Jim for clarifying, so I'm guessing the DD's so "sense" a sub submerged with engines off? I don't really see how this is realistic since I did not hear any random pings when approaching the convoy in the first place...

you might be right.
I was confused by ryanglavin's story about the procedures DDs usually did .....
