SSGN Severodvinsk to Start Sea Trials in November

Fourth-generation Project 885 Yasen nuclear-powered cruise missile submarine (SSGN) Severodvinsk will pass state sea trials in coming November; upon their results, the sub will be commissioned into Russian Navy in Dec 2012, said an insider in Russian defense industry on Sept 4.

"After the shipyard's sea trials, Severodvinsk returned to Sevmash and currently undergoes testing of torpedo tubes.

In mid-Sept, the sub will take the sea for the fourth time in this year to hold another round of trials. State sea trials are scheduled in November, and then the state acceptance board will commission the sub into the Navy", reports ITAR-TASS citing the source.

"It is a single-shaft submarine powered by water-cooled and water-moderated nuclear reactor with one turbine", he explained.

"Three batch-produced Caliber supersonic cruise missiles with flight range exceeding 2,500 km have been already manufactured for Severodvinsk", said the insider. "Under way to a target, Caliber missile changes flight trajectory in altitude and course. Moreover, velocity of a warhead after separation from the missile increases and approaches hypersonic speed", the source added.

"It is a high-precision ultra-speed weapon primarily designed to counter aircraft carriers", he said.

The source confirmed that in accordance with contracts signed by Russian defense ministry and United Shipbuilding Corporation under arms procurement program, seven Yasen-class submarines are to be built by 2020, including six subs made under modified Project 885M. The lead submarine SSGN Kazan is under construction at Sevmash shipyard.

"Strength hull of Kazan is almost completed", said the insider. In mid-Aug, Russian Navy Commander ADM Viktor Chirkov said SSGN Severodvinsk would join the Navy in the current year.

"Trials of the sub are on schedule. Hopefully, Russian naval ensign would be hoisted on Severodvinsk by the year end", reported Interfax citing Chirkov.

On Aug 15, a spokesman for United Shipbuilding Corporation denied information about faulty trials of the submarine, reported Vzglyad newspaper.

"Nuclear submarine Severodvinsk is successfully undergoing the shipyard's sea trials in the White Sea in full accordance with the pre-scheduled program", pointed out the official.

On Monday, a source of Interfax said that Yasen-class SSGN Severodvinsk would be commissioned not earlier than 2013 due to problems in powerplant.

Recall that the first trial round of Severodvinsk lasted 3 weeks. It was discontinued when "minor defects" were revealed in the new sub; to eliminate them, Severodvinsk had to return to the yard.

The next trial round passed smoothly. The sub spent about 2 months in the high sea. Experts of Sevmash and naval servicemen tested onboard systems at that time.

SSGN Severodvinsk is a double-hulled single-shafted nuclear submarine with reduced acoustic field rate. The conning tower has hydrodynamic oval shape; strength hull is subdivided into 10 compartments.

2,500km missile against aircraft carriers is impossible, they probably talk about a Land attack cruise missile......

APL "Kazan" will be the first submarine of the 4th generation with a completely new technical equipment

MOSCOW, September 7. (ARMS-TASS). Headache upgraded multipurpose nuclear submarine (APL) "Kazan" improved project 885M (code "Ash-M"), under construction at Sevmash for the Russian Navy will be the first submarine of the 4th generation with a completely new technical equipment, unmatched in the domestic military shipbuilding. This was reported by Itar-Tass source in the defense industry.

"In contrast to preparing for the reception of the Navy's strategic missile submarines of the 4th generation" Yury Dolgoruky "and" Alexander Nevsky "(Project 955, code" Northwind ") who first applied technical filling shall not exceed 40 per cent., The multipurpose nuclear submarine "Kazan" all systems, components and mechanisms will be brand new, never ever before not to use. This is a new high-tech equipment, which has no analogues in the Soviet and Russian naval shipbuilding, "- said the source.

"Submarine" Kazan "on its performance characteristics will be comparable to the most high-tech and most expensive U.S. attack submarine type" Seawolf ", and by the level of noise and some other parameters to surpass it," - said the source, recalling that Americans view the high cost of its submarines stopped their further construction.

He explained that the improved 885M project includes "the use of new hardware components of electronic equipment and weapons, as well as increasing the combat effectiveness of APL (ultra low noise level and increased detection range of underwater and surface facilities, particularly for submarines and surface ships). At the tactical and technical task to build a modernized submarine type "Kazan" was also on the demand of high-precision equipment ultrafast missile weapons. "

Another source in Russia's "defense," ITAR-TASS reported that the construction of "Kazan" is complicated by the absence of a contract head performer order - the United Shipbuilding Corporation (USC) with sub - enterprise cooperation in the delivery of components.

"USC is set up as soon as possible to sign contracts with about a hundred counterparts - leading enterprises cooperation. During negotiations USC, reducing their profits, on the other hand requires subcontractors to reduce the prices of their products in order to meet together in tough price parameters of the contract signed with the Ministry of Defence by submarine. However, large suppliers of products for "Kazan" yet do not want to reduce their prices on the pretext that the contract with the Ministry of Defense, which, according to their claims, the military department prices without economic justification, they are not signed, and the corporation , which should find a way out of the situation. "

"There goes the difficult process of negotiations with counterparties USC, started in November last year. Negotiators to agree quickly to catch up and a half years, who left USC to prepare contracts and MOD Project 885M submarines, including on the" Kazan " - said the source.

885M would indeed be a revolutionary submarine if it meets its design goal.

Exceeding acoustic characterictics of Seawolf would be something of an exceptional achievement even if one views it in terms of narrow characterictics of acoustics.

I would bet once she achieves that 885M would be acoustically the most quite nuclear submarine under waters and Western domination on the only field where their submarine were some what ahead would be broken.

I just hope their dont stop the 885M in this decade with 8 subs but utilise their number built to reduce cost and build atleast 8 more 885U or more advanced variant next decade while in parallel build 5000-6000 T medium size nuclear submarine of 5th Generation.

Wait, you want 16 885 sized boats plus small nuclear attack boats?

That would be overkill for Russia's defense budget.

May be not a over kill ,I am looking at long term prespective.

My thinking is Russian NAvy needs a force of atleast 30 SSN/SSGN.

Eventually the Oscar-2 , 971M and Victor-3 will get decommisioned next decade by end of 2030 even after their upgrade ( plus minus 5 years )

So a fleet of 16 Yasen class plus 15-16 5th Gen Small SSN plus 8 SSBN.

Its feseable and wont be expensive if they continue building Yasen.

For eg the first of Yasen-M cost 47 billion roubles and series production will cost 37 billion roubles .....if they build more they can reduce the cost by couple of billion roubles as it would be easy for subcontractors and equipment developers to order equipment in large numbers and at lower cost if the order is big and pass the benefit to MOD

Yasen is 3 times more expensive than Borei. So after the order of the 6 submarines, it will probably follow a cheaper project than can be produced at about 20 units. Some Aculas can serve for years also. So with that numbers we are over 30 SSN/SSGNs.

Not 3 times but 1.5 to 2 times ...the reason Virginia SSN is turning out to be cheaper because 30 of it are being ordered but in different block model with each block improved over others.

It turned out to have a cost of $1.5 billion compared to $3 billion for Sea Wolf class

The way I see it, is 1 for 1 replacement of current numbers (a leftover of the massive Soviet fleet) is not necessary + a financial burden.

The fleet is currently, at best:
3 Project 945/945A boats
4 Project 671RTMK boats
Around 12 Project 971 boats
Around 8 Project 949 boats

So what we have is 27 nuclear attack/cruise missile submarines.
Now, not all of those are likely to be included in the modernization process, and hence will not be part of force structure that will have to be replaced by new boats eventually.
Also we can add the Belgorod as a replacement boat....I find it extremely unlikely the Russian Navy will seek a 30 boat replacement, as that will actually exceed current force numbers, that are difficult to maintain as is.
I do agree that Yasen number should be increased past 8 to either 12 or 14 boats, or a larger number of smaller complimentary nuclear attack boats. However a smaller boat will be hard to fit a powerful cruise missile compliment into, so I don't see the Navy going for that.
Luckily with firm plans to maintain/modernize the Bars and Anteiis there is no huge pressure to build mass numbers of new boats until past 2020.
Then we can see what state the economy is, as well as contemporary submarine construction picture in Russia.

The key is cost , RuN will eventually realise that building more of Yasen class will be cheaper in the long run , A 5th gen small sub may still turn out to be expensive than Yasen class.

If the first Kazan cost 47 billion roubles of $1.4 billion and series production cost 37 billion roubles which is $1.1 billion ....it means the cost can be got down further if they build more of Yasen.

When I say less it means it may also turn out to be slightly more if you take into account the military inflation but a new 5th gen sub may be far more costly.

I think they were mentioning that 25-30 SSN/SSGN and 8-10 SSBN is the force structure for the long run which is feseable

No, the key should not be cost, but quality and more capable and allround subs.
A 5th gen sub must and will be be developed, not to say it should only be a SSN.
The Virgina is a SSGN, and only 115m. Thats rather small for a SSGN, i have no doubts the Yasen 120m, will have similiar capabilities. The huge Antei class of 155m is much larger, so the Yasen is actually a small and agile boat.

Perhaps the 885M will be classified as a 4+ generation, and numbers to form a strong core should be built. However, work on a 5 gen must already have begun, but time to hit the water isnt until 2030-2035.

Development never stops, but time scopes is longer now.

SSGN Kazan: First Radically New Sub in Russian Navy

Lead nuclear-powered cruise missile submarine SSGN Kazan being built under modernized Project 885M Yasen-M by Sevmash shipyard for Russian Navy will become the first fourth-generation nuclear submarine with absolutely new technical outfit having no analogs in national military shipbuilding, reported ITAR-TASS referring to an insider in defense industry.

"In contrast to fourth-generation strategic subs Yury Dolgoruky and Alexander Nevsky [Project 955 Borei] with only 40% of newly applied equipment, all systems of the multipurpose SSGN Kazan will be absolutely new, never used before. I mean radically new hi-tech equipment having no analogs either in Soviet or in Russian shipbuilding", said the source.

"Technically, SSGN Kazan will be comparable to the most hi-tech and expensive American Sea Wolf attack submarine, and even outclass her in silence and some other parameters", said the source reminding that the US had shut down production of those subs due to expensiveness.

How would Yasen use Big Decoys like MG-74 when it does not have dedicated tubes like those of Akula ?

SSGN Severodvinsk Completed Sea Trials Round

Nuclear-powered cruise missile submarine (SSGN) Severodvinsk has returned to Sevmash shipyard after successful completion of another sea trials round, reports the shipyard's press service.

"All tasks were accomplished in full", said Marat Abizhanov, defense production director of JSC Sevmash.

The submarine's missile system and various onboard facilities were tested during the trials.

According to experts, Severodvinsk passed the first significant milestone as the sub has spent 100 days at sea in the course of all sea trials rounds. The sub's commanding officer Capt 1 Rank Sergei Mitiayev congratulated the crew and trial team on that achievement and wished further success.

Recently, SSBN Alexander Nevsky also finished another phase of shipyard's sea trials. In the nearest time both submarines will start preparation for state acceptance trials.

As of today, SSGN Severodvinsk is the most up-to-date submarine in Russian Navy. She left the Sevmash's slipway and was put afloat in 2010.

SSGN Severodvinsk Started State Acceptance Trials

Project 855 Yasen nuclear-powered cruise missile submarine K-329 Severodvinsk will be commissioned into Russian Navy till the end of the current year. According to Izvestiya, construction of the sub cost Russia over RUR 70 bln.

Russian Navy Main HQ told Izvestiya that "on Oct 30 the submarine left Sevmash shipyard for the Barents Sea to hold state trials. It is planned to test all onboard systems and launch Caliber cruise missiles. If everything goes without failures, the tests would finish on Nov 25".

According to the interviewee, "maximum dive will be a final exam after the missile firing tests. That is the main test for any submarine, because deep water is where operation of all systems, condition of the hull and nuclear reactor are most demonstrative".

Severodvinsk has been passing such tests for the second year, writes Izvestiya. Last year, the submarine spent about 120 days at sea. Somewhat 2,000 defects were found then, said the source. It took one year to eliminate all defects revealed.

As for the source, "upon termination of sea trials, the sub will pass final overhaul at Sevmash within two or three weeks, and then she will be triumphantly commissioned into Russian Navy. The sub's crew is expected to start combat training in 2013".

I hope they manage to commission this subs before the end of this year it would be a great achievement for them .......this project has got delayed by a long shot.

I heard that Yasen incorporates GenIV reactor for her powerplant..hmm i wonder what kind of reactor it used ?.. as far as i know Gen IV reactor for subs would be a variant of Lead-Bismuth cooled reactor or variant of pressurized water reactor.. referred as "Supercritical water reactor"

Sodium cooled as the one used onboard Seawolf looks possible too but then.. from past experience Russians have no submarine running Sodium cooled reactor.. thus lead-bismuth is more likely candidate.

There are other 4 units of graney class order but i don't see any work on these so far

Severdovinsk has fired a cruise missile during testing- "Kalibr".

SSGN Severodvinsk Launched Newest Cruise Missile

Nuclear-powered submarine Severodvinsk successfully performed test launch of a new cruise missile and hit sea target during the state acceptance trials in the White Sea, said an informed source in Russian defense industry.

"During state acceptance trials at the White Sea, Yasen-class lead submarine Severodvinsk launched Caliber supersonic cruise missile from submerged position at a sea target. The target was successfully hit", the insider told ITAR-TASS.

According to another source, in 2012 the fourth-generation SSGN Severodvinsk has spent over 100 days at sea undergoing trials. In 2011, the sub spent about 120 days at sea.

Russian Navy Commander-in-Chief ADM Viktor Chirkov said on Aug 17 that trials of SSGN Severodvinsk would finish by the end of the current year.

SSGN Severodvinsk is a double-hulled single-shaft nuclear submarine with reduced level of acoustic field. Conning tower has streamlined oval shape; strength hull is subdivided into 10 compartments.

For the first time in Soviet/Russian shipbuilding, torpedo tubes are located not in bows but behind central station; that enabled to use bow space for advanced sonar antenna.

Eight vertical launch tubes are designed for missile arms. Powerful weapon system includes supersonic cruise missiles and multipurpose deep-water homing torpedoes. The sub is also equipped with state-of-the-art communication hardware and navigation aids, and powered by crucially new nuclear powerplant.

Introduction of latest Russian military technologies will make Yasen class the world's most silent and covert submarines.

Displacement of SSGN Severodvinsk is 8,600/13,800 tons; dimensions are 119 x 13.5 x 9.4 meters; test depth is 600 meters; speed is 16/31 knots; crew is 90 (32 officers).

It was reported on Oct 30 that Borei-class lead nuclear-powered ballistic missile submarine Yury Dolgoruky had finished state acceptance trials and was presented to Russian Navy for commissioning.

Shortly before that, the ex-minister of defense Anatoly Serdiukov said that commissioning of the new strategic submarine had been postponed again for spring 2013.

In May 2012, defense ministry signed three contracts for modernized Project 955A submarines; each of those 5 submarines will be capable to carry 20 Bulava ballistic missiles. The contract for designing of the lead modernized Borei sub named Knyaz Vladimir was tied with Rubin design bureau; for her construction - with Sevmash shipyard; for construction of 4 upgraded Borei-class submarines – with United Shipbuilding Corporation.

Therefore, eight strategic submarines are to be built and delivered to Russian Navy till 2020 under arms procurement program. Three of them are Project 955 Borei four-generation subs, and five are Project 955A Borei-A fifth-generation ones.

Is this true ?

То есть все "убийцы авианосцев" перевооружат на универсальные ПУ СМ-315 (как на "Северодвинске" и остальных пр.08853 Ясень-М, только там их 8, а тут будет 24). И смогут они нести 24 гиперзвуковых ПКР ОН "Циркон", или 72 сверхзвуковых ПКР ОН "Оникс", или 72 ракеты комплекса оружия "Калибр" (ПКР дозвуковые со сверхзвуковой атакующей ступенью, ПЛУР, КР морского базирования по наземным целям тактической и стратегической дальности, до 5500км). Умрите амеровские АУГ сразу в порту и не мучайтесь. Учитывая десяток (примерно столько удержат и достроят если "Белгород" и кого-то там еще) таких подводных крейсеров в боевом составе и до 20 в итоге "Ясеней-М"... сами посчитаете суммарный залп...
