Project 955: Borei class SSBN

Russian Project 955A and 885M Submarines to get Noiseless Leak-Proof Pumps

The latest Russian nuclear submarines of projects 955A (codename Borei-A) and 885M (codename Yasen-M) will be practically undetectable for hydro-acoustic stations which are the main means to expose a submarine. The advantage will be provided by the latest noiseless domestically produced leak-proof pumps. Previously all Soviet and Russian-made submarines were equipped with pumps produced by the Gidrotekhnika scientific and technical center in Moldavia, the Izvestia daily reported.


Each submarine has ten pumps which circulate liquid in the reactor, ensure submersion and surfacing, fill torpedo launches with water before engagement, cool the systems and equipment of the submarine. However their noisy operation is the main revealing problem of a nuclear submarine as hydro-acoustic stations of the adversary can hear it.

The unique Russian pumps were designed and are serially produced by the Blade Hydraulic Machines (LGM) enterprise. The Main Navy command told Izvestia the new sealless leak-proof electric pumps passed a full test trial cycle and were introduced into the technical projects of perspective nuclear submarines and those under construction.

The enterprise confirmed the creation of the pumps had been completed and supplies to the customer began. "The items and the production line have been fully created at the expense of the enterprise," LGM Executive Director Roman Pykhtin told Izvestia.


"All pumps meet category 4 requirements for vibrating hydraulic equipment. It is the top product category. A few companies produce such units in the world. Their characteristics are super secret as they determine the physical portrait of each specific submarine. If they are known it is easy to detect it on the background of natural ocean noise," he said.

The Gidrotekhnika in Chisinau supplied pumps for the Soviet and Russian Navy since 1962. Until recently the Moldavian products were purchased for all Russian warships under construction. The LGM pumps are a fully Russian product. They have a simple construction, small size and upgraded vibration and noise insulation. A pump operating at full swing can keep on its cap a five-ruble coin standing on its edge.

Expert Vladimir Shcherbakov told Izvestia the decreased noise of submarine systems and mechanisms is one of the major problems. "The noisiness of a submarine is caused by numerous factors. It is mostly the operation of the main power plant - the nuclear reactor, pumps, diesel engines, shafts, screws, water jets. In case of propellers and water jets the noise is decreased by the upgrade of the mechanisms. It is possible to decrease the noise of an operating diesel engine or auxiliary mechanisms by suspensions and rubber mats on which they are placed. It is more difficult with the reactor as it could not be installed on a vibration platform and covered by rugs. It is possible to decrease the noise by upgrading its pumps. The noise produced by constantly circulating liquid is the loudest on a nuclear submarine," he said.

At present nuclear submarines of projects 995A (five units) and 885M (6 boats) are being built for the Russian Navy. Only domestically-made equipment is used in construction. In future modular fifth-generation Husky-class submarines have to be laid and built with exclusively Russian-made systems and mechanisms, Izvestia said.

yeah i discussed about this with some of my friends....

I think the core information there is really just that the Pumps are now 100 Percent a russian product....

not the Noise reduction....

pumps has been regular updated over the years anyways....

Sensational article for navy recognition but its just normal routine for the Russian Submarine MIC....

Why do you assume that innovation is not relevant?  It is unlikely that the Moldovan company making these pumps would have had the resources to advance them.   In fact, like most companies it would have been resting on its laurels.   LGM has more than likely introduced substantial innovation and the article is not exaggerating this.  Innovation is typically achieved with a fresh approach from upstarts.

Because it isn't....  

the Russian MIC has been upgrading their pumps since the 60's.....      
Why the hell would you use pumps from the 60's in the era of 2000s...

The "Innovation" and i think was a good and necessary part is the fact that the Pumps are finally 100% russian made now which is good as it prevents it from getting hampered by sanctions.....
Not they upgraded the pumps....  

Upgrading the pumps has been an ongoing thing since ever....
its just not news sensational back then....  

Again, the Key point now is not that the pump is being upgraded but the fact that the new pumps will 100% russian made....

this is an opinion shared by ex-RuN sailors as well....

the upgrade itself is not really that Innovational as one would hype it...
its not like the Russians have attached a Caterpiller drive on their Yasens (Which would cool to see imo XD)...  

Something that i would find sensational is the fact that the Udaloys are getting UKSK VLS and other stuff...  
YES its OFFICIAL now that they are getting UKSKs....  

Now thats something big....  

But thats for the Udaloy Section!

MOSCOW, October 30. /TASS/. The first advanced version of the nuclear-powered ballistic missile submarine Project 955A Borei-class (North Wind) - the Knyaz Vladimir (Prince Vladimir) - will be floated out this coming November, Commander-in-Chief of the Russian Navy, Admiral Vladimir Korolev, said in an interview with the Krasnaya Zvezda newspaper.

Russia starts development of Borei-B nuclear-powered submarines:

Russia has started building Borei-B class strategic nuclear-powered submarines, chief of the Russian Armed Forces’ General Staff Valery Gerasimov said.
"Work to create the advanced Borei-B nuclear-powered missile underwater cruiser has started," he said at a Defense Ministry Board meeting.
He reiterated that the country’s strategic nuclear forces already started receiving Borei-class boomers.
"It made it possible to increase the share of modern strategic submarines to 82%," the general specified.
In five years, 102 ballistic missiles were bought for these subs, Gerasimov specified.
"Battle capabilities of the group of strategic nuclear-powered submarines increased by 25%, and the stealth and sustainability of the nuclear strategic forces also increased," the chief of the General Staff noted.
Gerasimov also reiterated that five Borei-A class nuclear subs are being built now. The last ship in this series - the Knyaz Pozharsky (Prince Pozharsky) - was laid down in December last year.

They said it would be in august, now november, then january, then april....

Russia starts development of Borei-B nuclear-powered submarines:

Weird when they haven't even launched the first A model yet

That would make it even weirder to make a B model now, unless Husky is sufficiently similar/based on Borei B?

Isn't the Husky a follow up on the Yassen?

Husky SSBN will be replacing Borei-B but they will probably start constructing those only once Husky design has been tested thoroughly and several SSN/SSGN versions of them are already built.

So my theory is that at least several Husky SSN/SSGNs and Borei-Bs will be constructed in parallel before first Husky SSBN gets the go ahead after last Borei-B is built.

That seems like a good theory

Big_Gazza wrote:Husky appears to be a common design family to fulfill the needs of SSN, SSBN and SSGN.  Common design solutions but with custom mission-critical modules.  SLBM missile tubes for SSBN, cruise missile tubes for SSGN, lack of both on SSN (emphasis on torpedo tubes).

The article says they are starting design work on Borei-B, not construction.  That fits with detailed development of Husky concept, never mind the use of "Borei" name.

But once sub is build as SSBN or SSN there is no way of adding or replacing modules right? its only about sharing design components?

Does the Borei class have a swimming pool and sauna like the Akula class?

Yes, and it is upgraded with hookers and blackjack too.

Crew comfort is second down form firepower in the list of most iprortant thins for a subersible thing to have. You need to check your mad science manual it will explain.

On a more serious note I know this is a silly question but the Akula has a pool and sauna so it is not so far fetched that the Borei might have a pool and sauna too.

There was plans for a night club but the shipyards said it would add 10 years to its construction.

They can also make the sub vibrate so that they have full body massage, its in option for export kilos too.

(in the voice of drill seargant Arch Dornan from Fallout 2) Can't you morons see that I was asking a serious question!

(dissclaimer please note that I was not trying to insult anyone with the use of the word "morons" it was for comedic effect)

I think you skipped my responce to ZoA in witch I explained that.
