One "Varshavyanka" and one "Lada": the Ministry of Defense signed a contract for the construction of submarines

The Russian military department has signed a contract for the construction of two diesel-electric submarines of projects 636.3 Varshavyanka and 677 Lada. The agreement was signed within the framework of the Army-2020 military-technical forum.

According to the information released to the public, the Defense Ministry signed a contract with the Admiralty Shipyards for the construction of two submarines - one Varshavyanka and one Lada. The details of the agreement have not been disclosed, neither the construction time is known, nor will the submarines be built for anyone. At the same time, Admiralty Shipyards are awaiting the signing of a contract for a series of diesel-electric submarines.

The general director of "Admiralty Shipyards" Alexander Buzakov said yesterday that the contract for a series of submarines of project 636.3 will allow the company to avoid idle capacity. According to him, already next year some of the shipyard's capacities will be free, but the Ministry of Defense has not yet decided on the construction of the next series of "Varshavyankas" for the Baltic fleet.

Well, we can conclude already this year. Well, the most extreme is the following. In 2021, already certain types of production will be free

- he said.

It should be reminded that Admiralty Shipyards have built a series of six Project 636.3 Varshavyanka submarines for the Black Sea Fleet, and a series of Varshavyanka submarines for the Pacific Fleet is currently under construction. It was planned that in 2020 the Ministry of Defense will conclude a new contract with the enterprise for another series of submarines for the Baltic Fleet.

It's time to start serial production of the 4th generation Lada-class submarines. In a year, the first serial 677Ds are to be handed over to the fleet.

So it has already begun.

677 "Lada

I did not understand whether VNEU (air-independent power plant) was finished or not?
There was no dancing there.

[newcomer]

They promise by the end of 23 reptiles. It is planned to install it on the P750b submarine.

[Victor_B]

"Lada" is she also from VNEU?

[newcomer]

So far, alas and ah.

[newcomer]

How can there be an order if this project in the present has not yet jumped off the Whatman paper?

[newcomer]

And the hedgehog until the snake?

[newcomer]

I would like VNEU to be everywhere, and what? The conversation is about the emergence of VNEU in principle, and not in particular specifically on the given boat.

[newcomer]

Here the question is different, the Moscow Region is not very satisfied with the electrochemical VNEU "Rubin", and the matter arose on the "handbrake". Let me remind you that Malachite has a gas turbine.

Only these P750B, like all other Malachite submarines of smaller displacement, did not interest anyone, there is not a single order.

The late Pashin answered the question of journalists what is the reason that Piranhas are not exported, answered very accurately - IN MALAKHIT

No, they are doing VNEU for the Lada submarine. They promise to complete the creation of VNEU for submarines of the Lada 2021D class in 2022-677. There are orders for these submarines from the Ministry of Defense of the Russian Federation and they are being built, and the P750b is a project developed on the personal initiative of Malachite and is unlikely to be of interest RF Ministry of Defense.

It may well be, but in the article

The Russian military department has signed a construction contract two diesel-electric submarines projects 636.3 "Varshavyanka" and 677 "Lada".

Those. VNEU will not be placed on these boats if the journalists have not messed up anything again.

[newcomer]

"Rubinovskaya" VNEU at the stage of bench tests. They promise to supply the B585 project. "Rubinovskaya" _ electrochemical, "Malakhitovskaya" _ gas turbine.
Perhaps “Rubin” will be able to complete bench tests before the end of 22.
They plan to install "Malakhitovskaya" on the P750B.

[newcomer]

“Ruby” made it in “hardware” in 18g. Bench tests are underway. It is planned to finish by 22nd.

[newcomer]

I am guided by Dorofeev's statement on "Army2020". This is the "Malachite" gendir.

but they have installation for submarines of limited displacement.

And why do we need a submarine with a larger displacement?

[Cyril G ...]

Quote from rudolf

For the North and the Quiet, we need more.

And here more / less. What is the main task of the North Sea and Pacific submarines? Support for the deployment of NSNF and General Purpose Forces. Here and something like Cupid-550 is enough ...

[Cyril G ...]

It is unconvincing ... Kamchatka boats, for example, will essentially have to operate in the Avacha Bay area no further ...
As for me, reasonable sufficiency for the tasks mentioned above is something like "Amur-950"

[Cyril G ...]

Actually, there is something. In Avacha Bay, the bay, if you like, the Americans and even the Japanese climb there ...

don't confuse your lip with the bay
in fact, 182 brpl operated up to the Indian Ocean

I was wrong, I wrote half asleep without including Moscow.

[newcomer]

So in the end, the selection is good, but the fact is the fact: "Ruby" is in the process of completing a stand. tests (end of 22); "Malachite" is just beginning, promises by the end of 23rd.

[newcomer]

I'm already tired of writing the same thing for the third time: Moscow Region does not want electrochemical, it wants gas turbine. The electrochemical principle of VNEU is a new word in installations.

[Fizik M]

Quote from rudolf

I have a selection of official statements regarding VNEU, LIABs and the Lada / Amur project over the past ten years. And everyone is filled with optimism. Even when Vysotsky freaked out about the "energy of the Second World War", but things are still there. The point is that we will buy Stirlings from the Chinese. The only hope still remains for Malachite, but they have a facility for submarines of limited displacement. Initially up to 1000 tons, now the bar has been slightly raised. Suitable for Amur-950.

everything is much more complicated there
We are looking for VNEU to put on boats in the early 2000s
the problem is in the low aggregate capacity, which, taking into account our conditions (flow), called the idea into question even on a submarine of dimension 877

[Fizik M]

Quote from rudolf

But this would be a very inefficient and extremely expensive installation.

everything was normal there - DZTs with O2 in the Dewar vessel
but ... obviously in very insufficient power
and with its increase, the noise level increased sharply

[newcomer]

I wrote a little higher: "The MO is not satisfied with the Rubin electrochemical installation. Therefore:" It’s still there. "

[newcomer]

Well, what am I talking about ?! Or do you just want to oppose? It would have been a long time since we had two installations, if the Ministry of Defense had not turned its nose.

[Fizik M]

Quote from rudolf

Project P750B, this is just an attempt to attract the attention of the Ministry of Defense

there are very interesting weapons solutions
including vertical ZPU for torpedoes and anti-torpedoes of 32cm caliber

[Fizik M]

Quote from rudolf

Yes, the boat is interesting enough. Malakhit's "our answer to Chamberlain", Ruby's Cupid-950 and the failed joint with the Italians S1000.

the answer is frankly bad
especially if there is a backlog of "Cupid"
we put on the A-950 VNEU (even if it is "Malachite") and he covers this Malachite product like a bull sheep

[Fizik M]

Quote from rudolf

and purely on a proactive basis

it's somewhat wrong
because the grandmother Malachite spends on this not his own (but not the Ministry of Defense)

I wrote a little higher: “MO is not satisfied with the Rubin electrochemical installation.

the phrase "dissatisfied" looks very strange when applied to a device that the Ministry of Defense of the Russian Federation did not finance

this is an alternative to "ruby" setting
moreover, "completely alternative"
because "malachite" has serious problems with aggregate power

Of course you want it faster, but even so, the main thing is that they build and transfer to the fleets ...

1. Low noise 877 (636) is ensured by the fact that an electric motor (low noise) from the AB works under water.
2. When the gas turbine VNEU is operating, what will be the noise level? Can someone explain? (I just want to understand).
3. Will it not turn out that we will increase the underwater autonomy and lose the advantages in stealth?

initially for VNEU they proceeded from the USBH 877 (and at a low-noise run)
and that was the problem
with the DZTs it turned out in the early 2000s, but the speed was at the level of 3 knots
if higher (and more powerful) - they began to "ring"

[Fizik M]

Quote: K298rtm

will we lose the advantages in stealth?

the message of "malachite" has the right to life - VNEU with the State Tretyakov Gallery with very high turnover
well, their power is small

[K298rtm]

High revs of the turbine will require a "gearbox" (speaking in automotive terms), that is, you will have to reduce the revs - this is not a very low-noise mechanism (in our industrial conditions). Well, how the industry worked with noise standards - this is without comment (you yourself know).

[K298rtm]

1. Thus, in the current version we have (in the submerged position): an electric motor (from the AB) works on the shaft. And there will be: turbine - generator - electric motor - shaft. And all this splendor should also provide a reduction in noise compared to the 877 and 636?
2. In the good old days (80s), a reversible converter was one of the significant sources of noise (there was such a good DS at 50 Hz).

[K298rtm]

If the turbine provides only the generator - the AB charge, and the electric motor will operate only from the AB, then the scheme is acceptable (in my non-mechanical opinion).

already on the 3rd knee she was very much removed
