I can't see it either...

Ok trying again:

Question 1

Question 2

You know the 3rd. Thanks AVGWarhawk. Unless I'm very mistaken though I have seen only the antenne rotate before, many mod configs ago. As I've said I may have been mistaken (late night the Capt needs just one more whiskey)

Concerning question #1: To me it looks a little bit like an extra anchor....:hmm:

#1 Could be a Y-tube sonar. Have a look at Norman Friedman's book: US Submarines through 1945. You may also find more info on www.navsource.org under the S-boats section.

#2 Is probably an early JK passive sonar. See the navsource website on the S-44

groetjes,

Thank you Gino, PacSubExp indeed! Seems to be the equipment you mentioned, very sparse info on its working's though.

Cheers

The first picture shows the three rubber transducer "rats" for the Y-tube sonar. This was a standard pre-war sonar outfit on the S-boats. The second "photo" shows the spherical JK sonar transducer. This was a later war-time upgrade of the S-boat sonar systems.

For more info on the S-boats, try this link:

Part three of the S-boats article should be posted soon.
