Chernavin on Bulava Design and Testing Problems

Svpressa.ru provided its version of this week’s comments from a Navy Main Staff source: 

“. . . there’s no alternative to equipping new proyekt 955 ‘Borey’ missile cruisers [SSBNs] with the Bulava missile.  Its acceptance into the arms inventory is delayed some, but the testing will be successfully concluded in any event and the missile will be accepted into the arms inventory.  There are no insurmountable obstacles to this.” 

Then former Soviet Navy CINC Vladimir Chernavin answered Svpressa’s questions about naval strategic systems.  He is still focused on what he sees as bad decisions in the process of designing and testing Bulava, rather than defective components and assembly problems.  But like most, he sees no alternative to Bulava at this point. 

Asked why the Navy doesn’t opt for Sineva, Chernavin said: 

“’Sineva’ is a magnificent missile, but it’s liquid-fuelled.  And this is a very dangerous ‘cargo’ for nuclear submarine crews.  The liquid fuel used in it is so corrosive, it burns through metal.  In addition, it’s extremely poisonous.” 

“In Soviet times solid-fueled missiles were put on proyekt 941 nuclear submarines.  But back then for technical reasons we could only make them in very large dimensions.  Proyekt 941 nuclear submarines had 20 90-ton missiles.  And each carried 10 MIRVed, highly accurate nuclear warheads.  The fact is one nuclear submarine [SSBN] could destroy up to 200 important targets, you can say, cities.  The biggest designer of missile-space equipment Vladimir Chelomey and his firm in Miass made all these missiles.  When I was still Soviet Navy CINC, we began to develop a missile [SS-NX-28 or Bark], like the ‘Bulava,’ to replace our heavy missiles on proyekt 941 boats.” 

Fleet Admiral Chernavin

Asked why it didn’t succeed, Chernavin replied: 

“Unfortunately, after Chelomey’s death, the continuity was broken.  One of Chelomey’s assistants headed the firm.  We gave it great resources to perfect this heavy missile – reduced dimensions, increased accuracy.  This work stopped with the USSR’s collapse.  And when the country’s leadership decided to restart it, they took as a basis not a naval missile, but the ground-based ‘Topol M.’  They changed design bureau accordingly.  The idea was tempting – to make one all-purpose missile for ground pounders and for sailors.  This would significantly reduce production costs.” 

But what was the stumbling block? 

“They didn’t figure that the firm that made the ‘Topol’ had no concept about naval missiles.  I remember a sad instance.  When ‘Topol’ specialists learned that a submarine-launched missile had to launch while the nuclear submarine is moving, they grabbed their heads.  Everyone knows ‘Topol’ fires from a stationary platform.  Everything in the calculations had to be completely changed.  The ground-based design bureau encountered problems that Chelomey had already solved, and it had to reinvent the wheel.  Another, to put it mildly, mistake was committed by cutting costs in the very course of missile development.  With Chelomey it was laid out as follows.   After the creation of a prototype so-called pop-up testing began.  We had an old specially reequipped diesel submarine in the Black Sea for this.  A missile tube was placed in it.  A telemetered missile is ejected from it.  Not less than two of such tests were needed.  Only after this did they proceed to other tests, of which there were a great number.  ‘Market consciousness’ in new Russian conditions gave the project’s directors the idea of economizing on tests.  There were no preliminary tests, but immediately they put ‘Bulava’ on a submarine and all steps were conducted with the wave of a hand, having skipped several phases of testing.  Now we all see what a ‘pretty penny’ this ‘economizing’ has cost the state.  The end of testing is not in sight, but ‘Bulava’ won’t fly.” 

 Does Bulava have any future?  

“I think there’s no longer time to give up.  Whether we want this or not, we have to get ‘Bulava’ in shape.” 

But what if its designers aren’t up to it?  

“I think they’re up to it.  They’ve hit so many bumps that they, on the whole, have gained experience and will guide it to the end, but again this will cost not a little money.  But less now than if we set out today to develop a missile from scratch.  Of course, in principle, it wasn’t necessary to let these people build a naval missile.  Now we have to get unscrewed.  And throw resources around.  But, I’m sure, they’ll still get ‘Bulava’ to fly.”

Bulava SLBM Test Next Month

Bulava

This afternoon a Navy Main Staff source told Interfaks the next Bulava SLBM test will occur in mid-August from modified proyekt 941 Akula (Typhoon-class) SSBN TK-208 Dmitriy Donskoy.  This is earlier than previously announced.  The Navy source also claimed that the new proyekt 955 SSBN Yuriy Dolgorukiy will be the launch platform for one of this year’s three planned Bulava tests.  He also reiterated that Russian military men are committed to Bulava, seeing no alternative to it as the Navy’s nuclear deterrent for the future.

In May, Defense Minister Serdyukov said three identical Bulava missiles are being assembled in the hope of discovering a common flaw in their construction.  Serdyukov said the next Bulava launch wouldn’t occur before November at the earliest.

Three Identical Missiles

The Defense Ministry’s inter-departmental commission didn’t make any announcement about its work or the causes of Bulava SLBM test failures as had been anticipated on 20 May.  If this commission has clues about the missile’s problems, it didn’t reveal them.  But Kommersant concludes that the Defense Ministry hasn’t reliably determined the causes of previous failed launches.

However, on 21 May, Defense Minister Serdyukov announced a new approach to Bulava testing.  The Russians will make three identical missiles and launch them in hopes of pinpointing the same problem in each.  It’s a gamble, but it could work.

RIA Novosti quoted Serdyukov:

“The problem of the unsuccessful ‘Bulava’ missile launches lies in the assembly process.  We do not see any other violations there.  The whole matter is missile assembly quality.  Each unsuccessful launch has its own causes.  They are all different.”

“Now we are working on making three absolutely identical missiles.  We believe that this will allow us to precisely locate the mistake, if there is one, since it must be repeated in all three missiles.  Now we are working on how to control the assembly process in order to know that all the missiles are identical.  Toward November, I think, we can begin launching the missiles.  After this we will be able to identify the cause precisely.”

Earlier reports had said the next Bulava test would occur in June, but Serdyukov now says November at the earliest.  Over six years, only 5 of 12 Bulava launches have been successful or ‘partially successful.’  The missile launched on 9 December 2009 self-destructed after a third stage engine problem.  Grani.ru recalled that other recent problems included steering system and stage separation malfunctions.  Moscow had intended to put the Bulava on its new Borey, or Proyekt 955, SSBNs starting in 2007.

Gzt.ru describes the new three missile approach as an expensive “hit or miss” method.  The Defense Ministry hopes launching identical missiles will point to the same problem in each, if there is one.  But if they still manifest different problems, Moscow will be no closer to pinning them down.  The risk is another year without getting any closer to a new SLBM.

Gzt.ru concludes:

“Serdyukov didn’t specify what will happen if in the November series of launches of ‘Bulava’ each time a different component of the missile fails.  Apparently, this possibility isn’t being considered.”

Also in Gzt.ru, Defense Ministry critic Konstantin Sivkov describes the three missile plan as absurd and expensive.  With each missile costing 300 million rubles, it’s a 1 billion ruble effort and there’s no guarantee the bug, or bugs, will be identified.  He believes the designers will have to conduct stand tests where all components can be checked under controlled conditions.  He blames defective parts allowed into the system due to inadequate production controls.

Gazeta.ru cited one Andrey Ionin, a missile designer, who agrees the problem lies in the absence of technological discipline in the enterprises of the Russian OPK.  He says:

“Cooperation by several hundred enterprises, working under different forms of ownership, in different parts of the country, without observing all rules of technological discipline is pointless.” 

Nevertheless, simultaneous assembly of three missiles could be a way of searching for mistakes in Bulava.

MIT missile designer Yuriy Solomonov has said repeatedly it’s defective materials, production process breakdowns, and the lack of quality control, but neither he nor military men are saying which materials or processes they suspect.  He’s also said Russia lacks 50 materials needed for solid-fuel missile production.

In Kommersant, former RVSN general Viktor Yesin claims the Defense Ministry’s inter-departmental commission investigating Bulava has determined that enterprises didn’t cooperate and provided poor quality parts for the missile.  Still he sees no alternative to Bulava and believes its design is workable.

Navy CINC on Bulava Findings and Typhoon SSBNs

Speaking Friday in Novorossiysk while accompanying Prime Minister Putin, Navy CINC Admiral Vladimir Vysotskiy said the Bulava SLBM commission will report 20 May on its findings regarding the last unsuccessful test launch.  He also promised:

“We are working continuously and checking the entire process of the missile’s development.”

“Continuous work of voyenpredy [military factory representatives] is being implemented.  Right down to a screw, with the submission of corresponding certificates.”

“. . . all enterprises active in Bulava production are working under control of military acceptance.  We are checking the entire process from beginning to end.”

RIA Novosti reminded readers that, despite a string of unsuccessful tests (only 5 of 12 have been considered successful), the Defense Ministry still considers it ‘unrealistic’ to put another type of ballistic missile in new proyekt 955 SSBNs.

In February, Defense Minister Serdyukov expressed his certainty that Bulava problems would not affect the laydown of the next proyekt 955 submarine, the fourth in the series.  Officially, Moscow says Bulava will be carried through until the necessary result is obtained, and the missile will be the basis of sea-based strategic nuclear forces until 2040-2045.

One has to wonder, what happens if, after all the emphasis on eliminating production defects, Bulava still doesn’t fly?  Where does Moscow turn next for answers.

Vysotskiy also told journalists two proyekt 941 Akula (Typhoon-class SSBNs Arkhangelsk TK-17 and Severstal TK-20) will remain in the Russian Navy’s order-of-battle until 2019.  He said:

“They will be in a combat condition until 2019.  They have very great modernization possibilities.” 

This isn’t the first time he’s said this, but he hasn’t said how the 1980s-era SSBNs might be used or altered:

“There are several options, but the decision has yet to be made.” 

Of course, TK-208 Dmitriy Donskoy was modified to be the Bulava test platform.

Trouble Building Submarines at Sevmash

Northern Machinebuilding Enterprise (Sevmash)

Here is 9 February RIA Novosti verbatim:

“Sevmash” Will Not Meet Schedules for Nuclear Submarine Construction Due to Insufficient Personnel

SEVERODVINSK, 9 Feb – RIA Novosti.  The “Sevmash” enterprise in Severodvinsk, Arkhangelsk Oblast will fall behind schedule in constructing nuclear submarines, it was announced to RIA Novosti on Tuesday in the enterprise’s press service.

Information about the lag in the schedule was heard in the session of the interdepartmental coordinating council which took place under the leadership of RF Government Military-Industrial Commission member Vladimir Pospelov and Deputy Navy Commander-in-Chief for Armaments Nikolay Borisov.

Members of the coordinating council discussed the state of affairs in producing nuclear submarines at “Sevmash” – “Yuriy Dolgorukiy,” “Aleksandr Nevskiy,” “Vladimir Monomakh” (project 955 “Borey”), and also “Severodvinsk” and “Kazan.”

“Today, as noted in the session, there is some lag from the construction schedule acknowledged by Sevmash and its partner-enterprises,” stated the press service’s announcement.

Factory General Director Nikolay Kalistratov explained the delay was caused by a lack of qualified personnel.

“It’s essential to apply maximum effort to realize the outlined plans and complete orders on time.  In the near future, we have to attract an additional 500 qualified production workers in the specialties pipefitter, machinist-fitter, ship finisher.  It should also be noted that over two years we’ve increased the number of basic production workers by 2,000 people, but this force is still insufficient,” said the director of the enterprise’s press service.

The directors of TsKB MT [Central Design Bureau of Naval Technology] “Rubin,” SPMBM [St. Petersburg Naval Machinebuilding Bureau] “Malakhit,” “Rosatom” state corporation, RF Ministry of Industry and Trade and other departments also attended the session.

Now at the “Sevmash” factory in various degrees of completion are three strategic nuclear submarines of project 955 “Borey” – “Yuriy Dolgorukiy,” “Aleksandr Nevskiy” and “Vladimir Monomakh.”  Work on construction of the fourth strategic nuclear submarine of this project, with the provisional name “Saint Nikolay” began in December 2009.  In all by 2015 it is planned to build eight nuclear submarines of this class.

This statement seems to imply there’s no problem with money, but, at a certain point, more workers equal money because higher wages should attract them, the northern climate notwithstanding.  So to some degree, this is a Sevmash call for more resources to do the work already on its order books.  Although these Sevmash officials said work’s begun on the fourth 955, RIA Novosti from 8 February made it clear there’s no firm idea of when its keel-laying ceremony would occur.  And Navy CINC Vysotskiy said the problem was “technological,” not related to the fate of the Bulava SLBM or to funding.  So maybe he meant a labor shortage, but, as noted, a lack of labor  is an inability or unwillingness to pay what it costs to do the work.

Yuriy Dolgorukiy SSBN has more sea trials before handover to the Navy. Sevmash says Aleksandr Nevskiy will be launched in 2010 (it was laid down in early 2004).  Vladimir Monomakh is about two years behind it.  The big question for these boats is when and if they’ll have a missile.  Late last year, a number of Russian media outlets claimed SSBN production was frozen due to Bulava’s problems.  But Sevmash’s call for more workers doesn’t track with that.  In October, the Russian government also announced Sevmash would receive 4 billion rubles to add to its working capital for modernization, along with a 6 billion ruble credit from VEB.

Thrust Control Problem on Bulava

Bulava Test (photo: IA Rosbalt)

 Aleksey Nikolskiy in Vedomosti reports that Bulava testing will resume this summer.  He says the problem in December may have been a defect in the third stage engine, not a design flaw. 

Tests may resume this summer from the modified Dmitriy Donskoy SSBN.  Yesterday ITAR-TASS reported a minimum of two tests would be conducted from Donskoy.  If successful, testing would move to the missile’s intended platform, the new Proyekt 955 Yuriy Dolgorukiy, this fall.  

A Navy Main Staff representative told Vedomosti that Dolgorukiy would need to fire several missiles in a salvo launch.  An industry source said, if all these tests were successful, a “preliminary document on completion of the first phase of testing” could be signed and serial production of the missile could start. 

The Defense Ministry and OPK commission investigating the December failure has provided optimism for those involved, according to a source close to the commission.  In his words, a third-stage thrust control mechanism produced by the Perm-based NPO Iskra failed in the December test.  So some conclude the missile’s overall design is sound and it makes sense to continue work on it. 

Mikhail Barabanov says “shock work” on Bulava might be risky, since MIT already promised that it could produce the missile quickly and cheaply.  Konstantin Makiyenko reiterates the lack of an alternative missile to keep a naval component in Russia’s strategic nuclear forces. 

Denis Telmanov in Gzt.ru adds that a Defense Ministry source has not excluded the possibility that another design bureau, possibly Kolomna Machinebuilding, has gotten orders to work on a missile.  The Makeyev GRTs is another possibility, but its deputy general designer responded that quick development of a missile was physically impossible.  He said, even from an existing system, it would take 5-6 years.  And he said no one in the country’s leadership has taken a decision to start work on a new missile. 

All stories repeated the expressions of support for Bulava from the Defense Minister and Navy CINC.
