Underwater telephone?

[Weisia]

I am reading a KTB of U-154 about a patrol in the beginning of '43 (http://www.uboatarchive.net/KTB154-5.htm). It says the commander Kusch tried to contact a close-by u-boat using a underwater telephone (Page 53 at 14.04). Does anyone know more about the use of this underwater telephone? Seems to me it would be of great use in a wolfpack attack.

If you want to hear how the US system sounded like

As a matter of fact, everyone should check out

For a list of really cooleo sound recordings of submarine operations. It rocks.


For the U-boats it would be called UT Unterwasser-Telefonie

"U 501" was stated to have been equipped with an underwater telephone, which was worked by the Petty Officer Telegraphist; it was added that, under favourable conditions, this could be used up to a distance of ten miles. Prisoners stated that underwater telephony was used during practices, but otherwise would only be used in a rare, extreme emergency.

Sonar could pick up the transmission easily.

If I was in charge I'd use it mostly to yell "FFFFFF UUUUUU" to overhead destroyers trying to depth charge me! :D

Or put a gramaphone record on like in the movie The Enemy Below.
