The Japanese Navy replenished with the first serial new-generation nuclear submarine of the Taigei type of project 29SS

The Japanese Naval Forces have replenished with another non-nuclear submarine of the new generation of the Taigei type of project 29SS "Hakugei" - "White Whale". The ceremony took place at the Kawasaki Heavy Industries shipyard in Kobe last Monday, March 20.

The new NNS is the second in the series and the first serial submarine of the new generation of the Taigei type of project 29SS after the lead Taigei - Big Whale, transferred to the Japanese the fleet in March 2022. The Hakugei was laid down at the Kobe Mitsubishi Heavy Industries shipyard in January 2019 and launched in October 2021. After that, it was completed on the water and passed all the necessary tests. According to the Japanese Navy, the submarine will be based in Kure.

In general, the Japanese are building a series of seven submarines of the new project, which are designed to replace the Soryu-class submarines. The new submarine has retained the overall shape of the previous generation of submarines, but has a number of design changes. The new submarines have a significantly reduced cabin to reduce hydrodynamic resistance and improve noise characteristics. Changes inside the submarine are also announced.

It is reported that the submarine has an improved snorkel system in order to reduce the signature, a new generation GAS. On the submarines of this project, a new sound-absorbing coating and materials are used that can significantly reduce the visibility of the submarine. In addition, the Taigei submarine abandoned the use of the Stirling engine, replacing it with new lithium-ion batteries.

The entire series will be named after large fish. The lead submarine is called "Taigei" - "Big Whale", the first serial "Hakugei" - "White Whale", the second serial Chingei" - "Fast Whale", etc.

Standard displacement - about 3 thousand tons, hull length - 84 meters, width - 9,1 meters. Crew - 70 people. It has six 533-mm torpedo tubes designed to use Type-89 torpedoes, and the Harpoon anti-ship missiles are also in the armament of the submarine.

Japan is rapidly militarizing, violating its own Constitution and Art. 107 of the UN Charter.
The Japanese Navy is already in many ways superior to the Pacific Fleet of the Russian Navy both in terms of the number of ships and their novelty.
This is a rapidly growing threat.

They get out of self-restraint and rule the constitution.

Prime Minister of Japan Fumio Kishida intends to continue work on changing the country's basic law, February 26 reports Kyodo News.

“The current time requires a revision of the constitution,” Kishida said during a speech at the congress of the ruling Liberal Democratic Party.

They are already buying Axes and making serious weapons of their own. The next block is the core. But, conditionally, if Iran does, for example, then the first candidates of the West are Japan and Korea.

Yeah, the rejection of a closed-loop engine still requires a diesel generator ... That is, we are not the only ones with Lada who noted this way here

[Normann]

Well, well, read about Soryu-class submarines. They stopped installing them, and we never started.

Yes, of course ... Read about OUR submarines 615 and 615A projects

And what is the duration of scuba diving for boats of this class? I think 2-3 weeks, maximum 4. Accumulators have not yet reached their limit in development, work is actively underway. If the specified parameters are reached, these "dances with tambourines" - different VNEUs - become simply superfluous and harmful (like the same fuel cells with oxygen and hydrogen reserves on board). In addition, many VNEUs do not provide normal speed in the normal, surface state.

abandoned the use of the Stirling engine, installing new lithium-ion batteries instead.

Well, stupid I'm gone! They don’t read articles on VO. Otherwise, they would have known that the "stirling" VNEU is the latest underwater fashion and the "unfulfilled dream" of countries building nuclear submarines.

Yes, the USSR in this case would help the DPRK to get something similar or, on the contrary, asymmetric. The balance would be restored. But, the USSR is not.

[Saburov_Alexander53]

Yes, the USSR in this case would help the DPRK It also happened the other way around, when in 1968 the USSR was afraid to touch it, and the DPRK attacked the US spy ship Pueblo at the edge of its territorial waters. They fired, killed a few pin ... owls, boarded it and now it stands with them as a museum. The USA "washed themselves" and only made excuses that they managed to destroy all the codes and documents, without which the r / equipment is ordinary scrap metal. But we had a "mole" Johnny Walker at US Naval Headquarters who supplied us with the codes.

As history has shown, those to whom the "international" community for some reason forbids or interferes with militarization .... they are doing just that ... accelerated militarization and its possible use

Yes, and in Russian it sounds somehow ... . Some kind of gay series. It is not enough for us to have any peninsulas (submariners) at our borders.

Here is the news for the "sect of VNEU admirers". How is that?
And the boat is awesome. Nothing, North Korea has something to answer with!

Stirling is very good at stations for exploring deep space, and on a submarine its power is clearly insufficient, you have to put several pieces on one small submarine and you can only use them for an economical move. and then, despite the fact that, in principle, they can rotate the screw directly without a reduction gear, it is necessary to somehow combine the torques of two or more engines onto one shaft. In a word, stirling greatly complicates the design and operation of the boat, and at the same time, on its basis, it is impossible to build a single power plant for the entire range of submarine speeds, but let's say a piston steam engine (at the modern level) can be built, by the way, a piston engine can also rotate a screw without a reduction reducer. , for example, in the last century there was a noiseless passenger steam car Doble, where the connecting rods rotated the axle shafts of the wheels

Let me object and paraphrase a well-known saying: - The devil is not as good as he is painted! And that's why:
1. stirling is 2 times "noisier" than the same ECG, because has rotating parts and is capable of emitting low-frequency vibrations...
2. Stirling is not used as a single PH-NH engine.
But he still carried a semantic load: - an AB charge in a submerged position, ensuring an economy of the boat's progress ...
Reasonable question: so why then was he expelled from the PC?
Answer: - They probably thought that they had built very capacious and safe electric energy storage devices capable of ensuring the movement and maneuvering of the submarine for a long time to solve the task without surfacing to recharge the battery and move under the "snorkel". Again, the released volume and weight were probably used to accommodate conformal LIAB. And this is correct, given that their "whales" have been transferred to full electric propulsion. And their diesel generators are small and powerful, requiring not very much diesel fuel to run on a generator.
IMHO.
