I've been trying to look for type 212A pics but only found a few exterior pics wihtout any interior pic. I was wondering whether Celeon who shared few of his interior and exterior pics are willing to share more....especially if there's any more recent pics(I think at least 2 type 212A were commisioned on 2005 so it's been 2 years already in operational service. Wondering whether they might be weathered a bit especially the panel lines...

I'm going to use it for reference pic as i'm building a type 212A sub model kit.

Thx a lot btw

Yes, ive also tried to find more pics but there arent any.

If you have a torrent program or emule : Try to look for a video called "U-32 auf Schleichfahrt"

It is a docu from german TV which has lots of inside video footages : Control room, torpedo room, diesel room, hydrogen fuel cells etc.....

I could make some screenshots which show interesting things and post them if you like ...

Yes pls that would be helpful. I'm mainly interested in the exterior shots. Thx a lot Celeon http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif. It doesn't have to be many. Especially interested in below waterline weathered hull paint.

Grrr i just did a fatal mistake i drilled the holes on the hull. I never thought they were retractable........Now the model is gonna be half sufraced and half submerged. Either that or a closed sub tied to the pier.

Ok here is what i gained from the video :

Sadly i cant get any better snapshots as the video was recorded in pretty arkward format.

Just like the u.s Virginia class, the type 212 was fully designed on computers instead of drawing boards and is based on the idea of modularity.

All interior sections are removable modules. If a design improvement or new technology gets available you can build a new module and easily replace the old one without to build a total new submarine.

This saves countless millions and enables a navy to afford more submarines http://forums.ubi.com/images/smilies/25.gif

Here are some of these modules. When they are finished they get placed into the pressure hull of the u-boat. Just like Lego http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

Fabulous pics http://forums.ubi.com/images/smilies/25.gif . Wondering whether in type 212A the hull below waterline has the typical whitish spots due to prolonged exposure to salt water.

Arten't these pics supposed to be confidential or somethin?

Obviously not as they were shown in TV http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif


Nothing that is shown would be helpful to someone who wants to copy something.

You just see the things and devices but you dont see how they work and what makes them work http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif



This is one of the hydrogen fuel cells

The only useful thing would be to look inside it to get a clue how they managed to get such powerful cells so small http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

Thats is the old cell which produced 40 kilowatts http://forums.ubi.com/images/smilies/blink.gif


The new module produces 120 kilowatts http://forums.ubi.com/images/smilies/clap.gif

The real restrictions were made during the filming in a torpedo factory. http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif

They showed the brand new DM2A4 torpedo. The world's first torpedo that uses a fiber optical wire instead of a copper one. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

The data transfer rate is approx. ten times higher than those of the current Mk-48 http://forums.ubi.com/images/smilies/59.gif

So the torpedo does not just recieve data anymore but has enough bandwith to send data back to the submarine at the same time.

This way the torpedo can actively collect sonar data while on the way to its target and becomes a sonar drone. http://forums.ubi.com/images/smilies/winky.gif


The noise of the torpedo is of no disadvantage anymore as it sensors give you sonar data through that wire which would normally be unavailable for the submarine as the torpedo's propellor noise does overshadow other sounds.

That means that you get a even better sonar awareness of your surroundings while using a weapon rather than a worse which was the case before.

Got a couple questions about type 212A:

One

What's the maximum range of the new heavyweight torpedo?

If you happen to know Kilo class well its weapon loadout is totally different from the Akula though the tube diameter is the same (standard 53cm). This makes the Kilo although very quiet in slow submerged speed have to approach to within 5nm(at least in a sim) of enemy sub/surface ships in order to have a good chance of kill. This of course diminish its lethality considerably.

So what's the range of the topedoes mounted in type 212A?

Two
The Sweden's Gotland class which is the first operational AIP sub uses the sterling AIP system. It uses liquid oxygen and helium to convert heat into mechanical movement(Thermodynamic process). The oxygen and fuel are used to burn up/heat up the helium which makes the pistons being pushed by the expanding helium(at 200 Celcius) then the cooled helium(25 degree celcius) which is contracting would pull back the pistons. Sea Water is being used in the process(i think as a coolant) and is dispensed from the sub without bubbling.

So what is the difference between type 212A AIP system to that of Gotland. Both use exactly the same liquid oxygen and helium gas.

Three

As type 212A claims that it uses a cavitation free propeller. Does the torpedoes use the same cavitation free propeller?

Four

The periscope is using infrared? I thought infrared is inferior compared to Low Light television technology which can see much further.

The DM2A4 is a 53cm diameter.
There are two different versions, a longer and a shorter one which differ by the amount of batteries they use.

The long one has four batteries which give it a maximum range of 27 nautical miles (50 kilometers). It is seven meters long.

The shorter , cheaper version (propably the export version) has only a single battery, no wire guidance and is classificated as a medium speed and range wake homing torpedo. Its only 4 meters long.

Both version have the obligatory re-attack capability.

I doubt that its propellor is cavitation free, this seems physicly impossible to me at that rotation rate.

The warhead uses 255 kilograms PBX Hexogen/ Aluminium.

But the launch tubes use the silent "swim-out" system. http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif

Both are totally different system designed to achieve the same but the 212's system is stealthier http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

The 212 uses hydrogen fuel cells.

The cells use a reversed electrolysis process to connect hydrogen and oxygen atoms to water molecules.

This process creates electric energy which is used to power the u-boats systems.

There are two advantages towards a Sterling system.


1. The Sterling system operates through heat which needs to be brought out of the sub by using a coolant as transport medium. (Seawater)

Heat is detectable and can give away the position of the submarine when the enemy has the necessary sensoric capabilities.

2. The Sterling system, although not really noisy, consits of moving parts which cause vibrations which create sound.


Hydrogen fuel cells produce no significant heat that would require a cooling system and therefore does not need to be brought out of the sub.

That means that the type 212 produces no detectable exhaust heat at all.

Additionaly the cells have no moving parts at all which means they produce only a qiet hum when operating. Even in the sub the hum can be barely heard.


To summarize :


A submarine with Sterling system has three major sound sources

- Sterling system
- Electric motor
- Propellor

The type 212 has only two

- Electric motor
- Propellor


Thats why it is the quietest among the quiet submarines http://forums.ubi.com/images/smilies/25.gif

Well, i believe its infra-red. Sadly i dont know enough about that periscope. Its name is Sero 14

I only found this pdf from its manufacturer Zeiss Optronics

What is actually a 'swim-out' system? Why it is more silent?

btw does type 212A still retain/is equipped with a snorkel? I believe snorkel was first used by the kriegsmarine. Now afer more than 50 years are they still being used?

And what the hell is that square fine rod attached to the aft tails? I've not seen them before like in the Collins or Gotland or Sjoormen which all use an X tail configuration for effective littoral operation.

A "swim-out" system moves the NOT yet running torpedo gently out of the tube. This does not make any sound.

When the torpedo has reached a certain distance to the sub its motor goes to full power and the torpedo goes on its way.


So far torpedoes were started at full speed in the tube and pushed out with force by pressurized air.

This makes a very loud noise and gives the position of a submarine away as soon as it fires a weapon.



Yes, all conventional submarines have snorkels as they still use diesels. http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif


To those rods..... I really dont know for sure what they are.


I believe they might be there to prevent that the towed array gets into the propellor when the sub makes a tight turn.

They also seem to have vibration dampers on them.
