Raising/Lowering Periscope

Lorddreaman · 02-24-08, 11:14 PM

What I would like to know is if escorts can hear your periscope going up and down?

no... but they can see it sticking out of the water if you raise it high enough, and they can detect a raised scope with their radar if so equipped.

Would they be able to in real life?:hmm:

Not that I've ever heard of, or read about.

some mechanical sounds on board the u-boat could be heard on hydrophones, but the sound of a periscope being raised would be likely bedifficult to hear even if you were standing next to it.

period hydrophones simply were not that great - at least not to the point of being able to hear such a quiet noise.

In GWX escorts are very good at spotting your scope. Both, in game and RL they could not hear it.

Maybe on a real quiet enviorment and really close to the sub they were able to... I mean, they did not only detect screws, that's why the captain would demand silence on the boat. Anyways, I think such sounds were only taken seriously if heard several times in repetition and roughly at the sime bearing, so as to dismiss any casual weird "natural" sound.

In the book Iron Coffins, the author Werner describes as follows, 'The periscope motor hummed continually'. I am guessing that this sounds could be heard from within the control room or from within the conning tower above. I would go along with the general concensus here that ths sound of a periscope being raised/lowered would not be picked up by a sonar operator on a surface vessel.
