The lead Turkish diesel-electric submarine with VNEU of the Type-214TN project has started sea trials

The lead diesel-electric submarine of the Reis class (project Type-214TN) called Peri-Reis, built at the Gölcük Naval Shipyard in the city of Gölcük in northwestern Turkey, entered sea trials for the first time. The submarine, equipped with an air independent power plant (VNEU), is intended for the Turkish Navy.

The submarine, named "Piri Reis" in honor of the Turkish navigator and cartographer of the Ottoman Empire, was launched last year and, according to the plans of the Turkish military, in 2022 was supposed to replenish the combat strength fleet. One, for unnamed reasons, the construction was delayed and the submarine at the end of this year is just starting sea trials.

The second submarine of this series, named Khyzyr-Reis in honor of the Turkish corsair and naval commander Hayreddin Barbarossa (1475–1546), who became an admiral of the Ottoman Empire, was launched on May 25, 2022 and is now being completed. In general, the entire series of six submarines with a German air-independent fuel cell power plant should be built before 2027. The Type-214TN project itself was developed on the basis of the German Type-214 submarines, which are the export version of the Type-212.

The construction of submarines is carried out in conjunction with the largest German shipyard HDW (Howaldtswerke-Deutsche Werft), the contract was concluded in 2009. Shares in production are divided as 80/20, where most are assigned to Turkey. HDW assembles only the basic body and mechanical components and some secret components, including fuel cells and propulsion systems. All electronic components and weapons systems are manufactured and installed in Turkey.

The length of the submarine is 65 meters, the total underwater displacement is 1860 tons. The boats are made using stealth technologies, equipped with a combined diesel-electric / anaerobic (VNEU fuel cell) power plant. The declared duration of being under water is more than 10 days. Speed ​​under water - up to 20 knots, on the surface - 12 knots. Diving depth - up to 400 meters. Armament - eight 533-mm torpedo tubes capable of firing Harpoon anti-ship missiles, it is planned to use Turkish-designed torpedoes and missiles on subsequent submarines of the series.

"Black hole", the Turkish version ... Let's see what kind of animal stirred in this hole ..

"Black hole", Turkish version..

No, not "black", gray. I read somewhere that 214 differs from 212 in the type of steel case. The Germans did not give the Turks the secret of a non-magnetic case for export. But Israel seems to have the "original" 212 .

What do we get from this?
Except perhaps for the fact that Germany, at a minimum, building for itself on external orders, supports the excellent potential of designers and shipbuilders who can quickly reorient themselves to increase the potential of the Bundesmarine.
There were historical precedents.

Kriegsmarine submarines were much more of a headache for the UK and the US.

The Germans built (are building) 4 + 2 NPLs for the Jews under the DOLFIN (dolphin) type 800 project, which is based on project 214. At the same time, the Israelis have 10x533 NTA, and not 8 as it was according to the project. Under VNEU at 4,0 knots, the boat can pass 1248M - just like type 214.

It’s interesting, isn’t it, Turkey is already building diesel-electric submarines with VNEU. And how many diesel-electric submarines with VNEU do we have in service?
Here it is.

[Doccor18]

Turkey is building, but VNEU is German.

[Smoker]

At the moment, the only full-fledged VNEU is a nuclear reactor. The Americans do not worry about this and are building nuclear-powered ships. The technology is gradually honing and improving. Varshavyanka is relatively cheap and there is an infrastructure for them - I think this is the main criterion now ..
There is no need to stop work on the non-nuclear VNEU, but there is nowhere to rush. We need to create a truly safe, simple and powerful anaerobic installation. With a huge oxygen tank on board, it's pointless to talk about safety. The nuclear reactor is also not the safest invention, and an alternative is certainly needed. And for any re-equipment, money is needed, and the fleet can simply absorb it in billions - and now the fleet has where to put the money without VNEU

Americans, with their space budget, don't have to worry at all, but the rest... Atom is very difficult and too expensive for many.

Debatable.

It should be borne in mind that cryogenic oxygen is stored outside the pressure hull, which somewhat reduces the risk of fire and explosion on board the submarine. And if Malachite succeeds (they promised to do it in 2023!) then our units should receive a single power plant based on a closed-cycle turbine. This will be a step forward even compared to the Germans and Swedes. But for now, something is "silence in the compartments."
AHA.

What's the difference? When the German-Turkish "Goeben" sailed the Black Sea, the Russian sailors did not feel any easier - whose project?

[Doccor18]

it didn’t get easier for sailors - whose project?

I agree, it is not easier for sailors.

[Normann]

And where is VNEU for the Lada project? We can nuclear submarines, but not diesel-electric submarines with VNEU?

[shikin]

VNEU are different. To have on board, in addition to a diesel engine, batteries (not lithium by any chance?), And also hydrogen - that's another "pleasure". The Chinese are coming up with something with safe lithium batteries, this would be the best option for today.
And the question is - what kind of autonomy is needed for boats like Lada? If for the Baltic or the Black Sea, as well as the coastal guard, then without VNEU it will be enough.

[Normann]

air-independent power plant - which one is different? Where is the engine?

[shikin]

VNEU happens with a Stirling engine - in Sweden, it happens on fuel cells - in Germany, in the French - a closed-cycle turbine, the Japanese make an electric one on lithium batteries. Lots of information on the Internet.
The frets have full electric propulsion (a diesel engine turns the generator, an electric engine turns the propeller shaft from the generator or from batteries. More battery capacity means more underwater range. Now an underwater range of 650 km is being announced.

[Normann]

The fact is that no matter what type of engine it is, it doesn’t exist ((VNEU - no. We are not discussing now - what type of submarines is better, and what type of engines is preferable for them, VNEU is fifteen years old, if my memory is lying, they can’t do it, or even twenty ((

[shikin]

So maybe there is no urgent need to hang out underwater for 20 days in coastal waters? The Japanese seem to be gradually abandoning VNEU with Stirling in favor of large batteries. For good, boats with VNEU should be of a class between nuclear and conventional. But so far this is far from it. Almost all boats with VNEU have an underwater speed of 2-3 knots. For normal running, diesel is still installed in most cases. And the dimensions of such boats are hardly designed for large reserves for the crew.
And VNEU for the sake of VNEU? I think we have not yet found a rational solution to the existing problems. From a technical point of view, there is nothing beyond us.

[ALARI]

Why all these toys? We look at what practice has shown in the NWO using the example of aviation - having even a dead air defense, you can multiply the effectiveness of aviation to 0. We don’t talk about drones, they don’t spare them and they are the main ones, as it turned out in the air. Can he take a preemptive step and throw all his strength into sea drones? The times of Tsushima, jutland, wolf packs, and generally dashing linear battles are over. It is necessary to prepare for future wars, and there a person is not sitting in a ship or submarine, but at a keyboard in a bunker.

Well, yes, well, yes ... That's just WATER - not air! And from the shore you can’t control underwater drones (UUVs) much. Therefore, the Germans are already making NNS type 212CD, and the Italians have laid down two NNS under the 212 NFS project, which, according to the "partners" idea, will be control centers for NVs for various purposes. But, mind you! PU drones (NPA) are on board the NNS, in the SEA, and not on the shore!
the Americans, they are working on NPA with AI, also produced in the RDB with the 5th generation PLA, and they will work under the control of the KP (PU) located on the carrier. Ours also hinted in terms of Wishlist with NPA on the 5th generation multi-purpose submarine of the ARCTUR type.
But it's all in R&D. So far there are not even "prototypes", so, only projectors. But the direction is already clear.
IMHO.

And we can’t make VNEU for many years, we can do nuclear reactors, but we can’t do something much simpler. (((

My deep conviction is that it is worth entrusting this "non-core" task to geeks from ROSATOM, and in a couple of years we will have the best AIP in the world.
But for some reason this is not done. Why? -- unclear!

We know how to build huge submarine cruisers, which sometimes have two nuclear reactors on board, and VNEU (((sorry, MAPL is easier.

Does anyone else watch TV? For fifteen years, or even more, I did not look. Watch ads?

[TermNachTer]

VNEU is by no means a panacea for all problems, and secondly, no one will transfer this technology to the Turks. As in that joke about Georgians: "You yourself will pass it on))))

[agond]

"Type-214TN" this should be a new version of Type-214 developed by Germany. Displacement surface 1690 tons, underwater 1860 tons buoyancy reserve of only 9%, this suggests that it is single-hulled. With such a modest size, 8 torpedo tubes with 12 533mm torpedoes and VNEU based on hydrogen fuel cells
