Defective Bulava Nozzle

That same highly-placed RIA Novosti source in the Navy Main Staff also said the next Bulava SLBM test will occur in August or September from Dmitriy Donskoy.  A favorable outcome would led to another test launch from Dmitriy Donskoy, then a third launch from the missile’s intended platform Yuriy Dolgorukiy.

RIA Novosti also reported a source — close to the state commission investigating the cause of the last failed Bulava launch — said yesterday that the cause of the unsuccessful December 2009 test was a malfunctioning rocket nozzle.  He said:

“The state commission established that the nondeployment of Bulava’s extendible nozzle between the missile’s first and second stages was the cause of the last unsuccessful launch.”

He added that the nozzle problem was not caused by a design flaw, but by a production defect, and the missile was simply made incorrectly.

RIA Novosti recalled that First Deputy Defense Minister Popovkin, on 30 June, said only that the commission had recommended continuing Bulava testing.  He didn’t comment on any conclusions on the cause of the last Bulava failure.

Factory Testing Update for Yuriy Dolgorukiy

Translation, no commentary . . .

“MOSCOW, 21 July.  ITAR-TASS.  The crew’s readiness to fulfill combat missions is being checked onboard the new generation project 955 ‘Borey’ ballistic missile submarine ‘Yuriy Dolgorukiy.'”

“As the press-service director Yekaterina Pilikina of Severodvinsk enterprise ‘Sevmash’ announced today, ‘the missile-carrier has returned from the latest phase of factory underway testing.  This was the nuclear submarine’s first at-sea period this year,’  she reminded.”

“‘The nuclear submarine was in testing more than two weeks.  Navigation equipment, the submarine’s buoyancy control system were checked, essential yearly checks of several of the submarine’s parameters were done,’ Pilikina announced. ”

“In the estimation of the chief builder for military equipment production at ‘Sevmash’ Vladimir Prokofyev, ‘the outlined plan was completely fulfilled.  There are issues which have to be worked out to prepare the boat for the next at-sea period which will happen in the near future,’ he noted.”

“‘While at sea, the boat’s crew’s readiness to fulfill combat missions was checked,’ Pilikina announced.  ‘The crew commanded by Captain First Rank Vladimir Shirin successfully completed all training tasks.'”  

“Earlier it was announced that before the end of this year the Russian Navy plans to conduct not less than three test launches of the ‘Bulava’ submarine-launched intercontinental ballistic missile, and from the ballistic missile submarine ‘Dmitriy Donskoy’ and from the permanent platform for this missile system — nuclear submarine ‘Yuriy Dolgorukiy.’  It is the first ‘Borey’ type submarine.

“At present in ‘Sevmash’ there are three more submarines of this type in various stages of construction.”

“The ‘Borey’ type submarines were designed in St. Petersburg TsKB [Central Design Bureau] of Naval Equipment ‘Rubin.’  According to open source data, several achievements in the creation of shipboard radioelectronic means and noise reduction are employed in the construction of the ‘Boreys.’  They will be armed with the new ‘Bulava’ missile system.  The nuclear submarine can carry 12 solid-fueled intercontinental ballistic missiles with a MIRVed warhead.  The submarines are outfitted with a surfacing rescue chamber for the entire crew.  The hull of the ‘Borey’ type nuclear submarine is 170 m, the beam is 13.5 m, the submergence depth is 450 m, and the crew is 107 men.  According to the Defense Ministry’s plans, not less than eight nuclear submarines of this project  are to be built.  ‘Borey’ is supposed to be the main naval component of Russia’s strategic nuclear forces in the 21st century.”

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.

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.

What Others Say About Bulava and Borey

New Borey-class SSBN Yuriy Dolgorukiy on Sea Trials

According to Navy Commander-in-Chief Vladimir Vysotskiy, the slight delay in the laydown of the 4th Borey SSBN unit came from “technological causes” unconnected with the problems of the developmental Bulava SLBM.  Vysotskiy also denied that there were any financing problems behind the postponement.  He said, “All preparatory work for the laydown was complete.”  The laydown was moved from 22 December to sometime in the first quarter of 2010.  Sevmash shipyard officials in Severodvinsk report that they weren’t told any more than that.  However, Vladimir Yevseyev of IMEMO told Gazeta.ru the delay in the next Borey is connected with the unsuccessful test launches of Bulava.  Yevseyev said, “There really is a connection with the postponement of the laydown.  The perspectives are unclear, two boats out, one building, but no missiles.  It’s only possible to put Bulava on boats of this class, therefore after the last unsuccessful launch they decided to wait it out, it’d be strange to spend so much money and lay down a boat without missiles.”
