Since i saw the first photos of the new type 212 im wondering of what use these "wires" between the rudders are ??

First time i saw them i thought theyre some sort of holding steel ropes that would be removed when the u-boat is finished but they are still there.

Im sure they have nothing to do with the function of the rudders but what are they ?

Anybody got an idea ?

Maybe some kind of antennas ?

Just a guess, but possibly a retractable 'cleet' for tug boats to tie on to perhaps.

look like structural support to me.

notice that other countries with the x-tail design have them surrounded by steel and not left hanging by themselves.

any membe of the modern kriegsmarine around?

anyone got a new janes maybe?

Sounds right. http://forums.ubi.com/images/smilies/16x16_smiley-indifferent.gif

Maybe theyve reduced the steel cages to steel ropes to make the u-boat more hydrodynamic ? http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif

As a marine engineer, I can tell you that those small pieces of steel would not provide much support, and it should not be needed. Seems like those might be guide wire to prevent the towed array from fouling in the screws. The attachment points also look like they are dampened to prevent sound. If you have ever seen a type 471 (Aussie boat with an X-helm) they do not have shrouds, but they deploy their towed array from a tube that extends past the propulsion system. If you have an unshrouded screw, then the towed array would be a major problem that must be addressed.

I heard some rumors that it has no active sonar anymore http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif

Can this be true ? Why remove it ?

The wires between the rudders is to prevent the torpedo guidance wire to be cut by the propeller.

Yet one more thing that you definitely would not want cut by an unshrouded prop!

I would hazard a guess at it being an alternative to the towed array, some sort of sonar device or something like that. I would bet good money on it being a device like that.

No, the type 212 has a towed array system. Besides, placing an array that close to a major source of noise defeats the purpose.

I think this is it.

Look at this picture. The towed array is mounted in the conning tower.

Now imagine it is extended and the boat dives.

The x-tail rudders would guide it directly into the propellor if these steel ropes werent there. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif
