Moscow could hold tender for helicopter carrier - source

14:49 22/12/2009


Russia could soon call a tender to buy a Mistral-class helicopter carrier, a defense industry source said on Tuesday.

He said "companies from several countries" would participate in the tender, mentioning specifically France, The Netherlands, and Spain.

He also said consultations were ongoing with France on the possible sale of a French warship.

"The Russian side reiterated its position that it needs not just one warship but technology to enable it to build such ships at Russian shipyards," he said.

He said consultations would continue not only with France but also with a number of other countries that had the relevant technology.

The chief of the General Staff earlier said that Russia would decide by the end of 2009 whether to purchase a Mistral-class amphibious assault ship from France.

The Defense Ministry has said a final decision should be based on "a thorough assessment of the effectiveness of [French] technology in the framework of domestic shipbuilding program."

Industry officials have said it is "senseless and wrong" to speak of buying weapon systems for the Navy without obtaining appropriate advanced technology for their subsequent production in Russia.

Deputy Prime Minister Igor Sechin said in late November that Russia could build its own helicopter carrier on a par with the French Mistral-class warship, and that the Defense Ministry could contract the United Shipbuilding Corporation to build it.

The Russian military earlier announced that it was considering buying one of the Mistral-class ships, worth 400-500 million euros (around $600-$750 mln), and potentially building three or four vessels of the same class in partnership with the French naval shipbuilder DCNS.

A Mistral-class ship is capable of transporting and deploying 16 helicopters, four landing barges, up to 70 vehicles including 13 battle tanks, and 450 soldiers. The vessel is equipped with a 69-bed hospital and can be used as an amphibious command ship.

Many Russian military and industry experts have questioned the financial and military sense of the purchase.

Russia's current arms procurement program through 2015 does not provide for construction or purchases of large warships, so the acquisition of a French warship is more likely under a new program, through 2020, which has yet to be developed.

Não faz sentido (agora) se iniciar um novo problema de desenvolvimento, pelo fator tempo/dinheiro.

Gostaria de saber apenas se houve alguma declaração das autoridades russas se o problema está sendo verificado no míssil ou no sistema de lançamento.

É tradição russa/soviética, desenvolver um sistema de setagem e lançamento completamente novo para tipo de SLBM que entra em serviço.

Aguardemos.

Russian Navy to continue development of SLBM Bulava – Navy CIC
Source: ITAR-TASS

Russian Navy Commander-in-Chief Admiral Vladimir Vysotsky considers development of sea-launched ballistic missile (SLBM) Bulava should continue despite its recent test failure. The Navy CIC denied replacement of Bulava with another missile.

"We'll continue [to work on Bulava]. Can't imagine how it might be replaced with anything else", said the admiral to ITAR-TASS. Answering the question whether it is possible either to create another missile instead of Bulava or to use army-approved SLBM Sineva (RSM-54) installed on Project 667BDRM Delfin SSBNs (Delta IV on NATO classification), admiral V. Vysotsky said: "It's impossible".

The firm date of subsequent test launch of Bulava is not certain, said another high-ranking military official to ITAR-TASS. "There will be no new tests this year, that's for sure. Speaking of 2010, nothing is certain so far", he said confirming that the Navy would continue developing Bulava.

The source appraised the suppositions of possible replacement of Bulava with another missile like Sineva as "groundless".

"Replacement of Bulava with any new missile is impossible", said the Navy spokesman. He explained that enormous funds had been invested in Bulava. Launching tubes of Yury Dolgoruky-type subs and the world's heaviest nuclear-powered submarine Dmitry Donskoy (Project 941 Akula) which is being used for Bulava tests are designed and partially produced just for that missile. Furthermore, it is impossible to replace Bulava with Sineva due to technical differences of those missiles. The first one is solid-fueled and dry-started; the latter is liquid-fueled, water-started and bigger in size. "To replace those missiles, one needs to break non-operative subs and build them again; in other words, to start from scratch and throw away abnormal money", explained the interviewee.

Faulty operation of third stage powerplant happened during 12th test launch of Bulava last Wednesday. Ministry of Defense Press Service reported to ITAR-TASS that "in accordance with flight development tests of SLBM Bulava an underwater launch was performed by SSBN Dmitry Donskoy at the White Sea on Dec 9".

"In-launch telemetry data was studied when the sub returned to base. It was found out that first and second stages had operated normally; the malfunction occurred at the third phase of trajectory", said military official.

"According to survey data, an unstable operation of third stage powerplant was registered", noted the MoD spokesman.

Causes of malfunction are being inquired by state panel on the missile flight development tests, informed the press service. The sub's crew had done its work properly, underlined the spokesman.

R30 3M30 Bulava is a sea-launched BM. That is the newest Russian three-stage solid-fuel missile designed as the basic weapon for perspective Borei-project SSBNs. It was developed by Moscow Thermotechnics Institute. The missile carries up to ten hypersonic maneuverable independently targetable nuclear reentry vehicles capable to change flight trajectory in altitude and course and to defeat targets at the distance up to 8,000 km. It is planned that SLBM Bulava will constitute the basis of perspective Russian strategic nuclear force till 2040-2045.
