Modernization of two titanium "Barracudas"

According to RIA "News"With reference to the Zvezdochka Ship Repair Center in Severodvinsk, on May 14, the Russian Ministry of Defense signed a contract with the company that provides for the modernization of two multi-purpose submarines of the 945 "Barracuda" project with titanium hulls.

The press service of the company clarified that the K-239 Karp submarine has been at the plant for 10 for years, and the Kostroma K-276 submarine will be delivered this year. After modernization, they will remain in service for another ten years. The timing of the repair work has not yet been announced, but it is known that the Karp reactor has already begun to unload fuel.

According to the representative of the Russian Navy, by the end of 2020 fleet there will be more than ten modernized multipurpose nuclear submarines. In particular, K-239 Karp will return to operation in 2017, having received modern equipment and weapons comparable to the latest submarines of Project 885 Ash.

The construction of the 945 and 945А submarines for the Soviet Navy took place in the 1979-1990s. In the manufacture of the case, titanium alloys were used, which reduced the mass with equal strength. Barracudus full speed is 35 nodes. As part of their weapons six torpedo tubes caliber 533 and 650 mm, and ammunition includes up to 40 torpedoes, cruise missiles and sea mines.

Why should he whiten something? The US has 60 multipurpose nuclear submarines. Each year, 1-2 new nuclear submarines are commissioned. Often ahead of schedule. We won’t be talking about surface forces either ... He will turn white, maybe when we put into operation as 2 Ash tree a year ...
Modernization of old ships is rather a necessary measure. Caused by both financial and organizational-technical problems. But let it be so, than nothing.
PS Recently, Barack Huseynovich has turned whiter more on the political front ... And that, mainly, because they are weaned from any opposition ...

Right. cleverly thought out actions, but due to a difficult situation. If we had launched a series of new multi-purpose nuclear submarines, they would be actively and quickly put into operation, then the meaning in the 2 nuclear submarines, even titanium ones, would be small. But realities force ...

[mpa945]

then there would be little sense in 2 submarines, albeit titanium ones. But realities force ...

Well, firstly not two but four.
Secondly, if Malachite brings to mind the modernization project, then plus six more 971. In total, ten aircraft with an identical composition of weapons and main vehicles, and very good and very "close" project. Isn't it a series?

[Bronis]

Quote: mpa945

Well, firstly not two but four.

That's when 4 will be, then "first". “Secondly,” these are still different boats. Nor "in the main". one way or another, modernization simply cannot replace new boats. It allows you to tighten the performance characteristics of the old, to extend their age. that's all. The solution is perhaps the only possible one in our realities, but not "brilliant", as they sometimes try to present. Besides, they would promise less and do more. And then managers, for example, USC cheerfully report on plans and intentions, but traditionally poorly report on the results ...

[mpa945]

Well, there are 4 of them since 1993.
Secondly, these are initially very close projects in both armament and basic equipment. TTX almost coincide. Not for nothing that the project of modernization of both was transferred to Malachite.
Well and in the main. USC does not plan, does not design, but executes orders. I hope the work will be fixed.

Multipurpose submarine of the Northern Fleet K-239 Karp of project 945 (code Barracuda) and the same type of submarine K-276 Kostroma, built in the 1980s at the Krasnoye Sormovo plant in Nizhny Novgorod, after modernization in terms of technical specifications designed to meet the submarines of the latest fourth generation of the Ash class. First, the Karp fleet will be repaired and returned to the fleet, then the Kostroma fleet. The Russian Ministry of Defense is betting on the modernization and return to operation of nuclear submarines of existing projects, therefore, in the future, two other titanium nuclear submarines - Pskov and Nizhny Novgorod - an improved project 945A (code "Condor") will be repaired. After modernization from the initial configuration on the submarines will remain almost only durable hulls made of titanium alloy. The entire filling of submarines - from missile systems to nuclear reactors - will be completely replaced by a new one, similar or similar in parameters to the one equipped with the modernized Ash trees, the deepest boat modernization is 1,5–2 times cheaper than building new one. The ship repairmen said that the titanium hulls of the boats are in excellent condition. The work itself will begin this summer and will continue, according to the most optimistic scenario, for 2-3 years .. Perhaps the time will be delayed, because so far not everything is clear with the suppliers of components. After the Karp, K-276 Kostroma will get in for repairs. It is planned that the upgraded submarines of the Barracuda project will receive new sonar stations, combat information-control systems, radars with a radio intelligence station, and a navigation system based on GLONASS / GPS. In addition, the boat will be able to fire cruise missiles of the Caliber complex (Club-S), including on ground targets.

Boats of this class have tremendous potential for modernization ...
Due to their construction, they have a number of unique characteristics ... such as immersion depth ...

Not the coolest titanium boat project. Performance is slightly better than that of Los Angeles. Well, what remains of former greatness.

[sebast]

Undoubtedly not the best titanium apl project. But to compare Los Angeles with the Barracudas is not worth it. Tasks are different after all.

[mpa945]

Undoubtedly not the best titanium apl project.

Do you know the best?
What is your categorical basis based on?

[qwert]

Well, let's say Project 685, Project 705, Project 661. And the Barakuda are equal in characteristics to Project 971 built of steel. The category is based on the fact that titanium allows you to get nuclear submarines with characteristics SIGNIFICANTLY higher than nuclear submarines with steel hulls. And besides the fact that my conscript service took place in the Soviet harbor. It was there that the "goldfish" stood ..

[qwert]

Well yes. Los Angeles has the main task: tracking and fighting enemy submarines, and Barakud, as they say: tracking and fighting enemy submarines. Therefore, the tasks are different. Just do not understand what))))))
Naturally, judging by the presence of torpedoes of the caliber 650mm, Barakudas can be very successfully used against surface ships up to the aircraft carrier. But precisely for these purposes, we built nuclear submarines with the Kyrgyz Republic.
A versatility. Well, since the MiG-29 can also use weapons for ground targets, however, it is definitely a fighter for air combat. But if necessary ...
That is why I compared with Los Angeles, and not with Ohio. Do you think otherwise ?????

[Boa kaa]

Quote: qwert

Not the coolest titanium boat project. Performance is slightly better than that of Los Angeles.

It was after the adoption of 945 and 971 projects that the Yusers were forced to design and build the Sea Wool, because the Losi were blown away. And the Yankes definitely needed not only a quantitative but also a technical advantage over our new projects.

[qwert]

Is that what I wrote this excludes ???? Didn't I write that pr.945 is better than Losange? But, at the same time, does this exclude that Komsomolets plunged by 1000 meters, and the prospect 661 gave more speed to 10 (!) Knots.
I don’t understand those who, without really reading and thinking, immediately minus, and then they also say, but in other words ... Did the guys gather here? Or are lawyers economists ????

[mpa945]

Dear comrade!
I didn't give you any cons. No substantiation followed from your phrases. I also asked the question: "By what criteria." Well, you answered. Now you can argue about it.
The best project is not a prodigy. And the implementation of TTZ. Requirements are not presented in the project. In the project they are performed. And they were performed on most parameters.
To begin with, experiments with "unique" characteristics ended and were not carried out with the 3rd generation. The task was to create combat submarines. (And not a "record holder") At the same time, the composition of equipment and weapons for all multipurpose submarines should be as unified as possible. And that was done.
Of all the projects you have listed, NOBODY is able to HIDDEN break through anti-submarine lines and carry out LONG tracking of enemy’s submarines.
And this can be achieved by minimal means (due to the unification of equipment and weapons between all 3rd generation submarines)
And the uniqueness of Titan allows, in comparison with steel, to halve the radius of destruction of submarines with weapons.
Thus, "not the best project" to put it mildly ...

[Al_lexx]

Great news! Titanium cases cost a lot of money, and are practically not affected by corrosion, and the fatigue of this metal is much lower than that of any steel. Multipurpose submarines are now the main trend in terms of fleet saturation. They are part of the ocean fleets, as a support.

Moreover, K-276 of Kostroma has one shot down on its account. 11 February 1992 year in Russian territorial waters, she collided with an American submarine "Baton Rouge" type "Los Angeles". The “Crab” had a slightly damaged cabin designed for breaking ice, and the “Baton Rouge” had a fire after the collision. After the accident, the Baton Rouge nuclear submarine reached its base on its own and after some time was decommissioned.

Everything would be fine, but the phrase is alarming: "... The Zvezdochka ship repair center in the city of Severodvinsk, on May 14, the Russian Ministry of Defense signed a contract with the enterprise ...". The notorious "Zvezdochka" carried out repairs to the "Smolensk", as a result of which the cruiser was half killed. All their "cosmetic repairs" do not count, they do not want to (or cannot) deal with iron as required by the crew. It's great to sharpen the screws at Zvezdochka ...

[archi.sailor]

Well, as for me, the time of the "titans" is over. Steel piers rot and sink from them very quickly. The hull is very expensive to maintain (rubber on titanium holds very badly). Will the project be saved by upgrading to the level of "Ash"? Maybe it will save, but all this time and money, and a lot.

[mpa945]

Well, as for me, the time of "titans" is over

I am glad that this is a personal opinion.

Steel piers from them very quickly rot and sink.

And how many piers drowned?

The case is very expensive to maintain (rubber on titanium is very poorly maintained).

Rubber holds evenly.
No tread protection, anti-corrosion treatment. So the operation is just cheaper and much more.

Will modernization to the level of "Ash" save the project? Maybe it will save, but all this time and money, and big ones.

Modernization is planned for a single project with 971, the design is transferred to Malachite.
And in your opinion it is better to "cut"?

[mig31]

The defense is above all ...

[Giant thought]

The correct decision is to modernize such excellent submarines as the Barracuda, especially since after the modernization they will become even more dangerous for our enemy. I am glad that much less money and time will be spent than building new submarines. Good luck, shipbuilders, carry out all the work on time, or better - a little faster.

In fact, the submarine’s tasks are not to hang around the pier, but to patrol or escort!
As for the anti-noise and anti-radar coating, the technology is now not a couple of the 90th of the last century, there is no concern.

The Americans do this, starting with Sea Wool. By molding a polymer with a continuous supply of material. At the same time, they still manage to not smudge the antennas and sensors. This technology 3 times (according to their data) reduced the level of the reflected H / A signal. Others write that the signal dissolves altogether. At the same time, the thickness of the coating (single-hull boat) inside and outside is only 20mm. I think ours, too, will soon reach this point, as soon as there are elengas heated up to 20 * C.

from another topic, but nice ...

Novosibirsk Aviation Plant (NAZ) named after V.P. Chkalova will release 2014 front-line Su-18 bombers in 34 as part of the state defense order, plant director Sergei Smirnov told reporters on Wednesday.
"Last year we made 14 aircraft (Su-34). This year we are making not only a plan (16 aircraft - TASS note), but we will also release two aircraft above the plan," Smirnov said.
The plant plans to ship the first three aircraft at the end of May. Now the airline specialists are conducting a series of test flights.
The contract for the supply of 32 Su-34 aircraft to the Russian Ministry of Defense was signed with the V.P. Chkalov NAZ in 2008. In 2012, another contract was signed for the production of another 2020 such bombers by 92.

The fact that the Barracuda is a unique ship is an axiom, I was its first commander and we learned to sail together! But why even this decent publication publishes a lie !? My head K-239 (now B-239) is located at the plant, and Kostroma went to sea a year ago and is located in the north, where it is awaiting repair and modernization, and Rubin has to do the documentation. It remains to find out when it will start, the boat was designed in Lazurite. And so, as General Designer N.I.

- 949AM 04 units;
- 971M 06 units
- 945M 02 units
The characteristics of these submarines will not be inferior to, and surpass their foreign counterparts in individual indicators, for example, in terms of the ammunition load for strike missile weapons.
So that, all converge.

[chunga-changa]

Plans on pr.885 failed, sadly. In general, military shipbuilding turns into a black hole. They willingly absorb any money, and the only real exhaust is the modernization and repair made in the USSR, or new products for foreign customers. In fact, the fleets of India and Vietnam have already been rearmoured, and for ourselves, we’ll patch old junk even then.

[indeveral]

And where did you get the idea that the 885 project failed? What can not be put into operation for a long time? Unfortunately, the ship’s bookmarking time was at the most crap phase of Russian life. Hence the construction time. Moreover, they were constantly forced to redesign the filling for modern technologies and equipment. There will be no sick series, just like the Americans with Sea-Wulf. Well, on proven technologies, they will develop a new project.

[Aikusun]

Each ship is a combat unit, especially after modernization, all changes have occurred in recent years in electronics, so if a new filling is good, then a smaller mass with equal strength is generally gorgeous, you can create a mobile group of submarines if speed really more than the main nuclear powered ships. Not good at the question, so not sure. Nevertheless, the shells will be modern and this is important.

[Bersaglieri]

Eh, if the construction of the nuclear submarine pr. 945B had not been cut down (in different sources AB or AM appear. The code "Mars") in the early 90s, then "Ash" would not have been required:
http://ru.wikipedia.org/wiki/%D0%9C%D0%B0%D1%80%D1%81_(%D0%BF%D0%BE%D0%B4%D0%B2%

[mpa945]

Well, I would say that pr.885 is a replacement for 949. The tasks of the PLA and the SSGN are somewhat different.
In 885 they tried to combine functionality. Received the appropriate price. At this price, the tasks of finding and destroying enemy submarines have excessive capabilities (missiles are not fired at by submarines). At the same time, the cost does not allow to increase the grouping in an amount sufficient to counter the multipurpose and strategists of the enemy.
Therefore, I think it will be necessary to modernize, as well as build new PLA projects.

[Boa kaa]

Quote: mpa945

885 tried to combine functionality.

Paul, ours followed in the footsteps of the amers, behind their Wolves. Even the ship’s architecture is similar. And this is objective: there is nowhere to put such a spherical antenna, except in the nose fairing.

Quote: mpa945

Received the appropriate price.

For amers, ASBU pulled 50% of the cost of the boat (along with design). I think our costs lie in the same plane - RES are now expensive!

Quote: mpa945

The phrase is not correct. Tasks - tasks, and opportunities are a set of weapons and RES. But the idea is generally understandable. There is no need to chase after Elk and Virginia.

Quote: mpa945

in an amount sufficient to counter the multipurpose and strategists of the enemy.

Americans for this purpose made the Wolf (3 units in total). Ours on 885 also tried to hang up the functions of combating NK and delivering attacks on the BC. But it is known: specialized ships better solve a specific problem than universal ones, since they are sharpened for this specific task.

Quote: mpa945

I think it will be necessary to modernize, as well as build new projects for the PLA.

Definitely. I think a series of 8 pr.885 we will not be able to afford the money, as well as our "Si Wulfs" yusers. Therefore, we are waiting for the answer from "Virginia": inexpensive, perfect, lethal in all respects.

[mpa945]

Well yes. I agree completely.
But the missile system is an extra compartment. Therefore, the growth of VI, etc.
With acoustics, you can also debate, but I will not.
And about the wolf ...
I think that the task of countering the ACG will remain. Does the 885 question fully correspond to it? But to solve this problem, nothing another There is no new. And cheaper is unlikely to succeed.
And for anti-submarine tasks, you can find a cheaper but effective solution.
And the upgraded 945 and 971 one of them

[BIGLESHIY]

And in general, our submarines are the most submarine submarines in the world !!! They have no equal!

[Enot-poloskun]

I have a question, like a layman.

I read on our website that our submarines of old projects are quite noisy.

Can a deep modernization reduce the noise, and, accordingly, the visibility of submarines?

[mpa945]

I read on our website that our submarines of old projects are quite noisy.

To begin with, 945 and 971 are the third generation. I consider the first and second as old projects.
Not from the first buildings, but by 1993 the noise level was reduced to "natural sea noise".
Naturally, modernization based on these projects should further improve stealth.

[Boa kaa]

Quote: Enot-poloskun

Can a deep modernization reduce the noise, and, accordingly, the visibility of submarines?

Certainly it can and certainly will be held.
Let's start in order.Case protect the housing with a mono-hydroacoustic polymer coating, without seams between its individual elements. Install all cascade shock absorbers on the 2's, push them farther away from the case, cover with anti-vibration screens. Such measures will allow the 885 project to reduce noise at 30-45 dB.
Next. To establish a system for the active suppression of structural noise by the discrete component 50-500Hz. Install the new 4 YaR generation monoblock type OK-9. I would switch to full electric movement, abandoning GTZA as the main source of noise. I would install lithium-ion batteries as a backup power supply system for low-voltage HED.
Would have spent rearrangement of compartments according to the "Ash" scheme, but would not install the missile compartment. I would use a TA for firing both missiles and torpedoes. Moreover, I would increase their diameter to 650mm, install the grilles and ensure that they are fired from the TA by themselves, as the Germans did and are doing, and now the Yankees on Wolves.
With receiving ANEU I would certainly put it on the submarine, as a backup source of the ship’s movement on the moves to 6,0 nodes. You can add more. But if, at least 50% of the above is done, then the boats will meet the requirements of the day.

Install all mechanisms on 2-stage shock absorbers

Already stood on the third generation.

move away from the housing,

Yes there is not so spacious.

Such measures will allow for 885 projects to reduce noise by 30-45 dB.

That you got excited. 12 decibels is twice!
Monoblock yes. But the point of all is to increase the range of natural circulation in both 1 circuit and in the MTC (that is, work without pump starts)
AB - emergency power supply for power plants. Walking under the gad at low speed ... well, at low speed and GTZA is not too noisy.
For anti-submarine tasks, search performance is important. Therefore, you need to raise the minimum low-noise speed.
In addition, there is a problem to increase the time of maintaining the "low-noise" mode. These are auxiliary mechanisms "new"

I would use TA for firing both missiles and torpedoes.

You mean winged? Against whom to apply? Against the Papuans - we don’t spread democracy to them? And against the probable, a volley of 2 max 4 missiles at least along the NK at least along the coast, it seems to me, is futile. Only a place on the shelves will take.

Everything is correct, but it is better to deal with PN SOURCES than with WAYS OF DISTRIBUTION of energy to the aquatic environment

Boats of this class have tremendous potential for modernization ...
Due to their construction, they have a number of unique characteristics ... such as immersion depth ...

Great !!! And to add about 150 bottom-based Scythians (missiles) along the rivers and lakes, the country will have enough space. (“When, in three months, the American generals will drink champagne in honor of their victory, then they will hit them in full! ") Then the Yankees will wash themselves with their superiority. I am very glad that Humpbacked did not sell everything and that Blue-nosed did not drink everything!

When, after three months, the Amerikosovsky generals will drink champagne in honor of their victory, then it will go to them in full!

Something I did not understand .... What are you talking about ???

[KBPC50]

On the "Skif" submarine-based missiles. They stand under water and wait for the command. It is not very difficult to put it - the Siberian rivers have many backwaters, there are decent depths, besides this internal lake - there are also many of them. This has been written about for a long time. Oceanic staging is prohibited by agreements.

Well, you have fantasies, my friend! What is it that they are celebrating the victory ... over us? (We are preparing for them our crushing "lake-river" strike "Scythians")

Then the Yankees wash their superiority

They still need to realize this superiority against our country ... What if a bummer !? Then - sushi paddles! After all, they were sure of their invincible superiority between NK and the Aegis. But the SU-24 flew in with the Khibiny under its wing, and all their invincibility was covered with a copper basin ...
So it’s too early for them to drink champagne ... Bummer can happen again with these unpredictable Russians.
IMHO.

I mean that any evil must be punished! Sergiy RADONEZHSKY, in my opinion - not quite sure, said: "If we respond to evil with good, then how can we respond to good?" It's expensive, but worth it.

I don’t understand those who, without really reading and thinking, immediately minus, and then they also say, but in other words ... Did the guys gather here? Or are lawyers economists ????
Answered everyone above .... I hope it’s quite detailed

zvezdochka_ru:
We disavow some media reports that caused not only verbal controversy among the interested public, but even disputes over completely material half a liter.
1. About the contract for the repair and modernization of the 945 project nuclear submarines.
This state contract was signed not “just about”, but quite a long time ago - at the end of 2012. Immediately on two ships. Why this "news" has been rehearsed in the present, we do not undertake to explain.
2. About the started SNF unloading.
Unloading has not yet begun. While preparing for this procedure. Events will end this year.
Along the way, equipment is being dismantled that will not be used later (after modernization) on the ship.
3. About posing in boathouse.
The first "Barracuda" - "Karp" - is planned to be staged in the boathouse in 2015.
4. About placing the second ship of the project - "Kostroma" at the plant.
"Kostroma" is planned to be received by the end of this year.
Of all the details about the scale of the Barracuda's modernization, we can only report that it will be "deep".
For tasty - a picture. Just in case, we draw attention to the fact that the landscape as if hints at the time of shooting - the summer of 2013.
