Bismarcks anit-submarine/ mine
Hi,
Except for the pravane in Bismarcks bow, which of her anti submarine / mine hunting suites was visible on the hull below the water line. For example, Gneisenau's transponders were visible just above her pravane port in the bow

Re: Bismarcks anit-submarine/ mine
4 transmitter in the bulbous bow
1 transmitter each side just before frame 230
1 telescopic device about 1 m portside of the centerline between frame 169,98 and 171,35.

Marc, you got me on the telescopic device?
Were the 4 transmitters open to the sea water or behind some type of cover? Saw photos of Gneisenau and sister ship bow and the transmitter were in notches and open to the sea. Read a few places that say Bismarck's were enclosed, but if that the is the case they will surely have problems with a clear reading?

The rectangular transmitters are always open to sea.
Gneisenau's transmitters were protuded and embedded into more streamlined casings.
Bismarck's bow transmitters were installed into a horizontal recess of the bulbous bow similar to Tirpitz.

Re: Bismarcks anit-submarine/ mine
Thanks, cleared that up. Came across it in discussions over the years but always with vague excuses where to find the info. And the photos of Bismarck in dry dock also didn't help ether-way .
On the anti-mine. How many paravane booms were on the Bismarck? So far I only found 4 and 2 posts for the booms.
Regards.

Hey Herr Nilsson,
You wouldn't happen to have a nice diagram of Bismarck's passive sonar GHG installation, would you? Or indeed Prinz Eugen's?

Nothing nice, just a horizontal projection.

Hi Herr Nilsson
Much nicer than nothing! Thanks for this snippet. It is the first contemporary representation I have ever seen. I wonder if any US photos of the system before removal from PG and installation in USS Flying Fish will ever emerge?
