Germany launched a modern hydrogen fuel cell submarine


This latest submarine, despite its combat mission, uses the most advanced "green" technology. The submarine, type U212A, the side number U-35 (S185), is essentially the very first submarine, which uses only hydrogen fuel cells as its driving energy.

The German firm Howaldtswerke Deutsche Werft (HDW) began working on the 212 project in 1988 year. Three-section submarine hull. Shooting systems, torpedo tubes, submarine crew, central post, rechargeable batteries are located in the nose. In the aft part are the power plant modules themselves. Themselves as fuel cell blocks are located in the connecting cone section. One of the design features of the German submarine is the location on the fence of the cutting of horizontal rudders and X-shaped rudders at the stern, which provides the best controllability of the boat in a submerged position.



The special hydrogen energy element, which was developed by the German naval shipyard HDW, gives the submarine independence from nuclear energy and diesel-electric engines, which are used in modern submarines. The use of a hydrogen fuel cell has made it possible to reduce harmful emissions to the environment almost to zero and to use the energy and fuel available aboard the submarine in a highly efficient manner.



But, in addition to this, the submarine has a number of "strategic" advantages in comparison with other submarines.

So, thanks to hydrogen fuel cells, the submarine U212A can be submerged much longer than atomic submarines. In addition, due to the high efficiency of the installed hydrogen engine and the use of special screens made of non-magnetic alloys and ceramics, the submarine does not emit heat and does not emit noise.



Representatives of the Bundeswehr believe that the new submarine, armed with 12 controlled heavy torpedoes, is the peak of perfection in new German underwater technology.

Main submarine performance characteristics:
The length of the submarine 56 meters, width - 7 meters.
Displacement in submerged 1830 tons, in surface 1450 tons.
The speed of the submarine in a submerged position 20 nodes, in the surface - 12 nodes.
Power reserve 8 thousands of miles.
The maximum depth of immersion 700 meters.
The crew of the submarine 27 man.
The submarine is armed with 12 guided heavy torpedoes and 24 mines.

    The author's note on the duration of the underwater stay of this submarine raises some doubts. A nuclear submarine theoretically may not come up for a year or two, as long as there is enough food for the crew (although after such a period of time there will not be anyone who has gone crazy there, but I said theoretically). It is also not clear how the GEM works - how exactly the process occurs.

    The Germans did well. It’s quite a self-sufficient and advanced military-industrial complex for the Fourth Reich. Joke.)

    What interesting contours of the hull ..... Reminds a marine mammal.
    This can be called a Modern submarine and not like our "newest" "St. Petersburg"
    The truth is embarrassing 700 meters immersion depth ... something is a bit much.
    In my opinion, we thought about acquiring such a boat

    hydrogen is certainly good. but fucking is dangerous, I can imagine how mechanical engineers will shake, in the sense of safety.

    Something about the duration of autonomy, someone bent. And about environmental friendliness, it’s a masterpiece in general. (Like, let’s drown a Russian nuclear-powered ship with an environmentally friendly boat. Smiled) Doesn’t generate heat and make noise - huh, does it fart so hydrogen quietly, or does it still burn? And the screws do not make noise, or did the Germans cancel the hydrodynamics? And where does 12 heavy torpedoes fit in there? Well, I saw how much space 4 vehicles and 8 torpedoes occupy on shelves, on (667 bdrm) and not heavy torpedoes. and here it’s only 56m full length and 7m outer diameter. And 24 mines, and where do they put it?
    At RTM, the entire carrying is packed with torpedoes, and the bow of the ship occupies the floor of the ship.
    By the way, our newest St. Petersburg, a direct continuation of Varshavyanka, and Varshavyanka is a force.
    Obviously splurge, and it seems an article for internal use, the Germans please.

    It is by the way and is in service with Italy.
    On German sites, only 6 x 533 mm torpedo tubes are indicated
    , due to space saving, four pipes are located asymmetrically on the left side, two pipes on the right side of the midline.
    working depth 400 m
    2 weeks demon ascent record for non-nuclear boats.

    splurge say ... well

    Yeah, maybe longer than atomic ones under a little water ... well, autorunya, well, a joker ...
    but I’ve heard that the Germans will have the next underwater project on cow poop !!! so she finally does not need to pop up, she will flush it !!!

    The conversation is not about the fact that no one wrote this, but that it is a skillful PR.

    In general, in this regard, I envy their defense industry.

    If our technology and such advertising, the floor of the world would be armed, and they themselves would not remain in the loser ..

    We also had such developments, but so far they decided to settle in the old fashioned way. So to speak, it’s better to have a tit in your hands than to stay in the train.

    We have already armed the floor of the world.
    The Germans are working out promising technologies on real production models. And stepped far forward in this area and we poheril this direction and have to buy boats from them.
    As for the advertising company of our weapons .-
    I find it funny when they constantly say "... Has no analogues in the world ..."

    rumpeljschtizhe,
    to be honest, it starts to remind "if dakoba ..."
    Nonetheless:
    now they could arm not the credit but for the loot, actually reducing the cost of production, saving money and giving the army more good new equipment.

    As for "has no analogues" - for fun, name an analogue of at least a Kalash, which has the same quality set of valuable parameters (something like that, I can't name it otherwise).

    Look at the personal video of the fighters from Iraq, there with the M-16 only the fighter with the grenade launcher walks as a rule, and the rest of the Pindos with Kalash and PKshkami.

    Speaking of AK, I haven’t heard such a wording,
    at that time 1947 there was no need to advertise (we’ll probably remember for another 100 years which AK is wonderful) that no one argues that this is an excellent example of small arms.
    This is a fashionable term .. "has no analogues in the world ..." the trend of modern defense industry, which is modernized and immediately has no analogue in the world ...
    PS I saw a lot of photos of Americans in Iraq ...... they climb the buildings there with PPSh with screw-bolted screws and calimators screwed to the barrel casing fellow

    remember a little HISTORY.
    Yes, the first boats with engines on the WZ - experimental - such as the Walter project appeared in Germany.
    And what next, who dare?
    And the USSR - one turbine boat according to the scheme of Walter and 32 diesel boats of 615-17 projects - these were all 50 years.

    Who does not believe - come to Pushkin - to VVMIU - there is a full building of 615 pl - inside the school.

    Later we had the topic "katran".

    To this end, the BKZ was built in Paldiski - a coastal complex for refueling a boat with liquid hydrogen and oxygen.
    Only for the 1st, experimental, from 613 pr. Redone.

    I’ll tell you - the sheep of the dressing of his skin does not mean.
    One missile on the BKZ - and the caput of the entire submarine system with fuel cells.

    THE BEST IS INSTEAD OF LEAD-ACID AB - to introduce at least LITHIUM-IONIC.

    And there are even more advanced ABs with nanoinclusions in AB plates.

    And 20 days under water without surfacing - really.

    Harmful exhaust is really the most important drawback for military equipment. And the officers are probably recruited from gays, representatives of national minorities and green organizations.

    Smiled. Give the PPSh-tactical bullpup with an integrated underbarrel grenade launcher and a Picatinny rail.

    I think they lied about the depth! What kind of ecology can we talk about? -All means are good in the war! If the boats on hydrogen elements exceeded the atomic ones, then the USSR and the USA would have had them for a long time! Yes, and the speed of 20 knots is the level of the 40s years.

    but don’t drive it. I heard about this boat about 6 years ago. Then it was tested. And today it is the most inconspicuous boat. electricity is generated by fuel cells and does not produce noise. plus materials. and the speed is small, this is probably the optimal ratio of the speed of travel and the noise of the propellers

    "... due to the high efficiency of the installed hydrogen engine and the use of special screens made of non-magnetic alloys and ceramics, the submarine does not generate heat or make noise."

    not a good opponent, however ..., and even with small relative dimensions ...
