I think for combat situation as long as undetected, you use the Hydrogen cells. For torpedo-evasion you switch to batterie.
Don't shure about ''travel-'times... :hmm: (can you use both or only the batteries...).

I gues they can manipulate all type of engines whatever way they want, when situation requiers.

The Diesel is very much only an emergency backup. They are not expected to "charge batteries" under normal conditions during a trip, for all energy for board systems and engine is not coming from batteries, but directly from the fuel cells, the traditional diesel-battery-engine-concept cannot be compared to in this case - this is NOT a normal diesel sub with an added fuel cell. The engine is directly powered by the fuel cells. The energy in these fuel cells can only be replenished at harbour, by replacing and/or loading the cylindrical modules that store these ressources (they do indeed look like giant AAA battery cells, ) Normal operation of the the engine and screw is energized by the fuel cell only - always. Top secret propeller and fuel cell makes for so little noise at up to medium speed settings that the sub is described to be "undetectable by contemporary passive sonar even if sensors are just a "Katzensprung" away" (quoting a leading engineer of HDW in an interview with a defense affairs journalist at the beginniong of this year, a guy I once talked to). The same source told him that the "212 is easily the most "non-existing" sub in the water today."
The limited hull size (still much more room than in the 206 and 209) is referring to the roots of the project in the cold war. The 212 hull design was once meant for exclusive Eastern sea operations.

The duration of the sub beeing able to remain submerged without snorkeling or taking ressupplies is top secret, and various sources indicate various time frames from up to 3 weeks to up to 4 months. Since the sub is Germany's top intel gathering platform is is now meant to serve in that role globally, if wanted, and that requires long endurance capabilities. time and again German medias have pointed out that this sub can operate completely indepedent from surface (snorkelling, ressuplying) for "many, many weeks". That'S why some tend to think of it as "a nuclear sub without a nuclear engine."

but whatever - it looks damn sexy.

So, then Seeadler was right.
What about the water produced by the fuel cells? How much is it all in all during a trip? Is it collected or 'goes it out' somehow instantly? And when the second, is there a possibility to get on the water from inside the Boot while under the surface? I have read it is clean 'like destilled water'. So one could sell it... "Stilles Wasser U212 (TM) Copyright Deutsche Marine". The techno kids will love it! If they make good marketing, they can soon order the next toy. (would have to check the crew after coming back of course...) Or when all goes wrong and you are laying on the bottom somewhere, waiting for the rescue-team. (reines Planspiel natĂĽrlich...)

My 212



It is missing that front lip bit and I am going to fix that but still can't figure out how without having to remap everything.

Bow needs to be made a bit blunter which I have and I have added that lip.

I need to remap the model and put on a different screw.

Some how I don't think that is the real one....

No way they would display their screw tech for all to see

It's the first pic you get, when you enter "u212" in german google pic-search engine.
And it seems to be from a french site. (don't really know if I should count that as a pro or con regarding fake or not ... )

Would also say that it is fake...

Found this pic, you clearly see that the screw has an other shape.
