Nope. Those cables in modern German submarine designs are not for hold the stern planes up. They are used to prevent entanglement of torpedo wires with the screw. A close examination of the cables reveals rubber barbs and other devices to reduce cavitation.

To me screw dunce cap

To me screw dunce cap looks different to the previous released photos. There is a dome like thing at the end of it (if it's not an optical effect) while in the other photos it looked flat or even concave. Any thpoughts?

Could this be a modern version of the "Walter"technology from WWII.

No, it has nothing to do with the catalytic decomposition of hydrogen peroxide (H2O2), which was the basis of the Walter boat. In the simplest Walter scheme, hyrdogen peroxide was passed over a catalyst with rapid decomposition and heat generation. The heat was used generate steam, which was used to run turbines. The indirect Walter process, which was ultimately used was a bit more complicated, and included H2O2 decomposition and fuel combustion to raise steam temperatures further.

The Type 212A powerplant is a fuel cell system using special membranes that combine hydrogen and oxygen, resulting in generation of electricity and water as a byproduct. No hydrogen peroxide, high temperatures or steam generation involved. The electricity runs an electric propulsion motor, and also supplies the hotel load. Very similar to the fuel cells used in spacecraft (Gemini, Apollo, and Space Shuttle) to generate electricity.

Germans were always serious about their U-boats. During the past decades political limitations in u-boot displacement construction in Germany implied that paradoxically they built bigger and more capable u-booten abroad for foreing navies than for their own navy. Just consider that until recently the German navy was equipped with the small typ 206 which is an old design (late 60s) while their shipyards at home or abroad were constructing the more advanced (at least in hull design and propulsion) and bigger 209 familly, Dolphin and TR 1700. Nowadays with U212 the German navy has better U-booten than the ones they sold for export.

What is also interesting to debate is the fact that HWD is losing the race with the France/Spain consortium that produces the Scorpene diesel submarine. The Scorpene is replacing the old Typ 209s around the world, with only two submarines in service (Chile has recently received the first opperative Scorpene). Even Brazil that has being producing 209s until as recently as this year is considering the Scorpene.

I think the germans enter the race late with the 212 or the price and technology transfer they are offering is not the best.
