Hi Maciek

I had a look at U-995 Das U-Boot vor dem Marine Ehrenmal in Laboe By Wetzel, Eckard, and found one poor detail picture of the forward torpedo room on page 38. In the picture you can just make out the driving shaft and control arm, the picture is take sometime between 1943 and 1945. I then found a better picture of the forward torpedo room on page 151 taken sometime between 1965 and 1971, and you can see the motor has been moved up to the ceiling.

This may suggest that the Norwegians move the motor :-\

The Norwegians did a similar thing with the periscope on U-995 they replacing the old periscope with a new Type XXIII periscope.

Simon, your last post makes me think of two questions.

Approx when would the KM have started using that version of DF loop?  I'm wondering of course if I should try to make that for my model or leave it the round one it started as.

And the other one to do with torpedoes is, how close would the nose of a torpedo come to the inside of the torpedo door?  Or perhaps, how long is a torpedo and how long is the entire torpedo tube (assuming the torpedo is as far back in the tube as possible when ready to fire).

1.) I am not sure on this as I have not research this, but I have a picture of U-362 from late 1944 with the newer DF style. It look like almost (I may say all now) all the boats (Type VIIC & VIIC/41) that surrendered had one.

2.) Part 2 in the morning, time for bed.

Hi Simon,

Thanks, that really is a wonderful pic. Superb for lower hull weathering too.

Cheers,

Dougie

2.) There is very little room between the nose of a torpedo and the inside of the torpedo door, could be less than 50 mm. I am thinking around 30

Hi Maciek
Does this look like the correct layout for the piping for bank 6 (in red) ???

Thanks, Simon.



I think that hull valve a1 for HP Bank 6 is located here:



Then the lines go at both sides:

starboard:



and then to the Control Room, through the valve d



port:


(view from the stern)


(view from the bow)

The port line goes through the valve c2 to the mine ejection installation.

Hi Pat

Being looking today for pictures of the late war DF Loop. 

Found that U-1056 had one on 29 April 1944 or U-869 on 26 January 1944 - Not 100% on the dates

Boats with one, U-362, U-776, U-858, U-869, U-875, U-889, U-953, U-995, U-997, U-1023, U-1056, U-1165 & U-1305.

Yes, the top view layout looks correct.
Still not 100% sure, how does it look in front view...
