Submarine to Test New Missile

A new nuclear submarine will be ready to test the next generation of intercontinental missiles this year, a military shipbuilding spokesman said Tuesday.


The Yury Dolgoruky, the first of the country's new Borei class of submarines, has yet to fire the Bulava missile it was made to carry because of numerous failures during testing.

"By the beginning of the navigation season, all ships will be ready to carry out tests of the Bulava," said Alexander Kholodov, a representative of submarine-building shipyard Sevmash.


"This refers above all to the submarines Dmitry Donskoi and Yury Dolgoruky," he said.


The Dmitry Donskoi is an older Akula-class vessel used for previous Bulava tests while Borei-class submarines were undergoing testing.

The Bulava was designed to be carried on submarines like the Yury Dolgoruky, but repeated failures of the missile during tests have called the costly project into question.

The submarine's entry into service, carrying the Bulava, will be a major step forward for the military, which hopes to use rising oil revenues to increase its clout.

exacerbates nuclear woes

India conducted its first ‘peaceful’ nuclear test explosion, dubbing the operation ‘Smiling Buddha.’ But Buddha himself would at best have smiled sardonically at seeing his name tied to such an experiment.

After the test, India vowed never to weaponise its nuclear assets, a pledge that seems to have gone unheeded.
A decade later, the country again set out to test its nuclear capabilities in the Operation Shakti tests - five nuclear tests conducted over three days. Pakistan soon followed suit. It has long been clear that India intended to go back on its non-nuclear weapon pledge. Indeed, an early indication was the commencement of the construction of a nuclear submarine after the 1974 nuclear test. Nuclear drills, meanwhile, were reportedly being taught to every Indian naval officer as early as the 1950s by officials from the Bharat Atomic Energy Centre (BARC) in Mumbai, where India converts fissile material into nuclear weapon cores.

In 1976, Dr Homi Nusserwanji Sethna, the chairman of the Indian Atomic Energy Commission at the time, created the Diesel Propulsion Research Team (DPRT), an apparent subterfuge for designing a nuclear propulsion plant for India’s first nuclear submarine. A team of four naval officers led by Indian Navy Capt. PN Agarwala and Capt. Bharat Bhusan were inducted into the DPRT.

Many Indian Naval officers at the time were also trained in nuclear engineering at the Bhabha Atomic Research Centre (BARC) and subsequently transferred to the Defence Research and Development Organisation’s classified nuclear submarine project, which was called the Advance Technology Vehicle (ATV).

plan to buy old German U-boats

Navy chief Kamthorn Phumhiran is insisting on pushing ahead with the plan to procure six second-hand submarines from Germany, dismissing the other option of buying brand-new South Korean ones as being too expensive.

Adm Kamthorn yesterday said he would go ahead with the navy's original plan. It would be presented to the Defence Council chaired by Defence Minister Prawit Wongsuwon next week.
 
Gen Prawit had earlier voiced his support for the idea of acquiring two brand-new submarines from South Korea. He believed they would last longer than the decommissioned German ones.

The six Type U-206A coastal patrol submarines have been in use in Germany for more than 30 years and Adm Kamthorn admitted they had only another six or seven years of useful life left.

Though the South Korean Type U209 submarine is made using German technology, Adm Kamthorn said it is too big, with a displacement of 1,200 tonnes. "They also cost up to 13 billion baht each," he said.

Although the navy included the option of buying South Korean submarines in its feasibility study, it does not have enough money to buy the two new ones.

"It is most practical to buy the second-hand ones at a cost of 7.7 billion baht," said Adm Kamthorn, who also played down concerns over the usefulness of the submarines in Thai waters. "The navy has to take care of Thailand's marine interests valued at 900 billion baht a year. An investment of 7.7 billion baht will be worth it," he said.

If Thailand fails to secure the six submarines, the opportunity may go to Chile or Colombia, which are also interested in striking a deal with Germany, said navy Assistant Chief of Staff for Operations Thawiwut Phongphiphat.

A navy source said other countries in Southeast Asia have already strengthened their navies with submarines. Malaysia deploys two French-made ones, Singapore has four and Vietnam has three, with a plan to buy six more from Russia. Even Burma has already had its soldiers trained in submarine operations.

If the Defence Council and later the cabinet approve the navy's purchase plan, the first batch of 30 navy officers will be sent for a year of training in Germany before Thailand receives the submarines, said Vice Adm Thawiwut.

Navy Readies for its New Submarines

The Israel Navy is making advanced preparations to absorb two new German-made Dolphin-class submarines, IDF journal Bamachaneh reported in its latest issue. The number of soldiers selected for submarine warfare has grown by 30% in the latest IDF recruitment batches, in order to man the additional submarines.
The Navy currently has three submarines, also of the Dolphin class, so the addition of two subs means that the force is growing 66% bigger. "We are in mid-process and are slowly adding more crews to be trained for service in the submarines," explained Naval Instruction Base Commander Col. Ronen Nimni. "We are also taking care to add crew commanders who closely mentor the soldiers."

More officers are being trained for submarine posts as well. The number of cadets who will be trained for submarine command positions is rising by 35%.

Pentagon Said Likely to Back New Design for Ballistic Missile Submarine

The U.S. Defense Department is likely to pursue a brand new design for its next nuclear-armed submarine, following a Navy recommendation during a key program review earlier this month, according to experts and observers.

The Pentagon's Defense Acquisition Board on December 9 completed an initial design review meeting on the so-called "SSBN(X)" effort, spokeswoman Cheryl Irwin confirmed last week. However, she indicated the department was not ready to release the review's results.

If approved by defense acquisitions czar Ashton Carter, the replacement submarine for today's Ohio-class ballistic missile vessels would enter its first major acquisition program phase, called "Milestone A."

A recent Congressional Research Service report estimated it would cost roughly $70 billion to replace the 12 ballistic missile submarines expected to populate the U.S. fleet by the end of this decade. The nation currently fields 14 Ohio-class boats.

The Navy has not released total cost projections for the new underwater craft, but has estimated it would spend $29.4 billion on the effort between fiscal 2011 and 2020. That figure, though, excludes costs for roughly two subsequent decades during which the 12 new submarines would be built and delivered.

The next-generation submarine is to initially carry today's Trident D-5 nuclear-armed ballistic missiles, but later could be fitted with new-design nuclear missiles and possibly conventional weaponry.

The first Ohio-class submarine to be replaced reaches the end of its 42-year service life in 2027. One subsequent vessel is slated to retire each year after that, with the last submarine expected to age out in 2040. The SSBN(X) submarines are to enter the fleet between 2029 and 2042.

One pivotal decision believed likely to come out of the Defense Acquisition Board review pertains to the approach the Navy will take in developing and building the replacement submarine. In an official "analysis of alternatives" that also has not been released, the Navy considered three possible design concepts for the Ohio-class follow-on, according to a recent Energy Department report.

Russian strategic sub recalled for inspection


One of Russia's premier nuclear submarines, slated to carry its next generation of strategic missiles, has been called back from sea trials, possibly delaying deployment, a top weapons designer said on Monday.

The Yuri Dolgoruky, Russia's first Borei-class submarine, was designed to carry the nuclear-capable Bulava intercontinental missiles, which the Kremlin hopes to make the cornerstone of its arsenal over the next decade.

"Right now the cruiser is returning to the shop. I think the work will last half a year," Yuri Solomonov, a top engineer at Moscow's weapons design Institute of Thermotechnics, told a news conference.

The Yuri Dolgoruky had been undergoing sea trials and was expected to go into service in the first half of 2011, and its recall to the dock for further inspections will likely delay its adoption into service by the navy.

The multi-billion dollar project is the most ambitious in the Russian fleet's post-Soviet history, but has been repeatedly delayed by a string of unsuccessful Bulava missile launches. Seven out of 14 test launches have failed.

Russia Launches Upgraded Submarine Missile Cruiser


The Russian Zvezdochka Shipbuilder has launched the K-407 Novomoskovsk, strategic submarine missile cruiser after an interim overhaul and modernisation programme.

Novomoskovsk is the last strategic nuclear submarine to undergo modernisation at the shipyard, and is to be delivered to the Russian Navy.

The vessel is the sixth missile submarine of Project 667BDRM (Delfin Class, Delta-4 by Nato classification), whose service life has been extended by ten years after the overhaul.

The Delfin Class submarines are armed with 16 intercontinental ballistic missiles and form the basis of the Russian sea-based strategic nuclear forces, according to ITAR-TASS News Agency.

The submarines that have undergone similar modernisation include K-51 Verkhoturye, K-84 Yekaterinburg, K-114 Tula, K-117 Bryansk and K-18 Karelia. (Source naval-technology)

NGV Tech wins work with Daewoo shipbuilder

Malaysian shipbuilder NGV Tech has signed a contract with Daewoo Shipbuilding & Marine Engineering to construct two 250-foot training and patrol vessels for the Malaysian navy. 

"In the period of 24 months, we will collaborate to design, build and deliver the naval vessels," NGV Tech Executive Chairman Datuk Zulkifli Shariff said.

"DSME will do the design. The vessel blocks will be transported to Malaysia and we will start joining it together at our 24-hectare shipyard in Sijangkang," Shariff said.

NGV Tech was founded in 1992 and is based in the city of Telok Panglima Garang, in the state of Selangor on the west coast of the Malaysian peninsula. Sijangkang is on the coast of Selangor.

The company offers design, fabrication, installation as well as repair and maintenance services for all type of ships including buoy tender vessels, offshore crew boats, patrol craft, landing craft, harbor tugs, hydro-graphic craft and strike craft.

NGV Tech builds around 40 ships annually in Sijangkang, generating around $160 million in revenues, a statement from NGV Tech said.

HMS Ambush: latest of Royal Navy's next generation of submarines

HMS Ambush, the second of the Royal Navy's new Astute class of nuclear submarines, is powered by a nuclear reactor the size of a dustbin.

It is 97m long, the equivalent of 10 London buses, and weighs 7,400 tonnes compared with the 5,000 tonnes managed by its predecessor, the Trafalgar class. 

It has the biggest "ears'' of any sonar system in service today, with the processing power of 2,000 laptops. 
The nuclear reactor which drives the propulsion system is roughly the size of a dustbin but will last the 30-year life of the boat without needing to be replaced. 
But there are some other big numbers to bear in mind - the first three Astute class submarines (HMS Astute, Ambush and Artful) cost the Government £3.8bn, according to last year's National Audit Office report, compared with an initial contract for £2.58bn. 
That report also showed the project was 47 months late, with an original in-service date for Astute of May 2005.(source telegraph.co.uk)

Indian Navy to Install AIP System on Scorpene Submarines

The Indian Navy is considering a proposal to equip Scorpene submarines, which are under construction, with an air independent propulsion (AIP) system to overcome the risk of detection.

The system, which is being built at Mazagon Dock, enables the boats to stay underwater without having to surface for more than three weeks.

DCNS CEO Patrick Boissier said the company was in talks with the navy and that the system could be integrated into the fifth and sixth submarines in 2018.

The navy is also looking at an indigenous AIP system, which is being developed by the Defence Research and Development Organisation, according to Hindustan Times.

The first Scorpene submarine is expected to enter service in 2015 and the remaining within a span of three years.

India is constructing six Scorpene submarines with transfer of technology from DCNS under a Rs187.98bn ($4.16bn) programme called Project 75. (Source naval-technology)

Submarines to receive new batteries

South Africa's fleet of three Heroine-class Type 209 diesel-electric attack submarines are to receive new batteries as part of their “first minor overhaul”, the Ministry of Defence and Military Veterans says in two answers to Parliamentary questions.

The battery consists of 480 man-sized cells and weighs 250 metric tons, according to a South African Navy briefing to Parliament last month. Navy Chief Director Maritime Strategy Rear Admiral Bernhard Teuteberg at the same briefing said a battery costs R35 million. He also described the overhaul as "major". 

“In order to ensure that the SAS Manthatisi (S101) will be operational for a period of at least eight years on completion of the first minor overhaul, the SA Navy will procure a new battery for the submarine,” the ministry says in answer to a Parliamentary question by Freedom Front Plus MP Pieter Groenewald. “Each submarine will, in turn, be fitted with a new battery on completion of their respective minor overhauls.”

Another answer notes the Manthatisi is “presently in reserve, and has been so since October 2007. The submarine is being prepared to become the first Type 209 Submarine to be overhauled in Simon’s Town Naval Dockyard,” the answer continues. “The SAS Manthatisi will be undergoing an overhaul in accordance with the laid down schedules for this type of submarine. The scope of work for the overhaul of SAS Manthatisi is currently being determined.”

The Manthatisi is the lead-boat of class of three submarines acquired for R8.1 billion as part of Project Wills,a component of the controversial Strategic Defence Package. She was laid down at Howaldtswerke-Deutsche Werft, Thyssen Nordsee Werke, Kiel on May 22, 2001, was launched June 15, 2004 and commissioned November 3, 2005. It arrived in South African waters in April 2006. Her sisters were both commissioned March 14, 2007. The Charlotte Maxeke arrived in South African waters in April 2007 and SAS Queen Modjadji I in May 2008.

In answer to Groenewald's question as to whether the repairs might be done in Germany, where they had been built, the ministry said the Navy was “not giving consideration to sending the submarine to Germany for repairs. The requisite capabilities are being sourced and developed locally, and these capabilities will form the foundation for not only the maintenance of SAS Manthatisi but also the subsequent overhaul of SAS Charlotte Maxeke and SAS Queen Modjadji I, as scheduled in the SA Navy Maintenance and Upkeep Plan for the Medium to Long Term Expenditure Framework.”

Russia delays Bulava nuclear missile test to 2011

Russia has delayed the next submarine test launch of its troubled intercontinental nuclear missile Bulava until 2011, Itar-Tass state news agency reported.

Russia has delayed the next submarine test launch of its troubled intercontinental nuclear missile Bulava until 2011, Itar-Tass state news agency reported on Wednesday.

The Bulava missile, which Moscow plans to make the cornerstone of its nuclear arsenal over the next decade, has failed seven of its previous 14 tests, endangering the future of the project which is estimated to cost at least $3 billion.

The next test had been scheduled for Dec. 17.

"The White Sea region, from where the Bulava was to be launched, is covered with ice," Itar-Tass quoted an unidentified defence industry source, who had been due to attend the test launch, as saying.

"The exact date of the next test launch of the Bulava in 2011 is not yet decided, but it will take place in the first half of the year," he said.

Test launches have sent the nearly 37-tonne missile from Russia's border with Finland to the peninsula of Kamchatka, in Russia's Far East.

Testing of a New Submarine to Start

“Alexander Nevsky” submarine has been launched at a plant in Severodvinsk. The vehicle is ready for final tests.
     
      The missile-carrying nuclear submarine “Alexander Nevsky” belongs to the newest generation of Russian submarines of the “Boreas” project. The vehicle will carry 16 “Bulava” ballistic missiles, as well as torpedoes for self-protecting.
     
      The submarine creators, who used cutting-edge technologies for building the submarine, believe that their vehicle would pass all tests successfully. Seven more missile-carrying nuclear submarines are 4expected to appear within the “Boreas” project.

Russia plans to build eight subs of the Borey class. The first one, “Yury Dolgoruky”, has already gone through tests and is currently preparing for launch of its first Bulava missile. The third sub in the series, “Vladimir Monomakh” is under construction. The fourth, “Svyatitel Nikolay”, has also been started, but will be modernized and constructed under new modification compared to the three others.

UK to launch its biggest, deadliest nuclear submarine

A nuclear reactor which can power a small city and guided-missiles that can pulverise an enemy more than 1,000 miles away -- meet HMS Ambush, the Royal Navy's newest killer submarine. 

The 'super-sub' can produce oxygen and drinking water from seawater to keep its 98 crew members alive in time of crisis. 

More complex than the US space shuttles and able to circumnavigate the globe without surfacing, Ambush is 291 ft long, the same length as a football pitch, as wide as four double-decker buses and 12 storeys high.
Its nuclear-powered engine can propel her at more than 20 knots, allowing her to travel 500 miles a day, reports the Daily Mail. 

And despite being 50 percent bigger than the Swiftsure and Trafalgar subs it will replace, Ambush is much quieter. Its propellers are the quietest ones, making less noise than a baby dolphin and undetectable to enemy vessels. 

Of course, that is if enemy vessels can get near Ambush. The submarine's sonar and radar are so sensitive that it can detect ships a staggering 3,000 nautical miles away. 

It means that if parked in the English Channel, Ambush would know if a ship left the New York harbour. A true titan of the deep, the 1.2-billion-pound warship will be launched at Barrow-in-Furness in Cumbria Thursday.

Putin pledges $860b to modernise military

Russia's Prime Minister Vladimir Putin said today that the government had pledged $860 billion through 2020 to modernise and re-arm Russia's military.
   
Russia's armed forces have demanded an increase in spending to modernise ageing infrastructure and weapons systems after years of insufficient funding, which undermined performance in local conflicts after the break-up of the Soviet Union.
   
"We are allocating very serious, significant funds for the rearmament programme. I am even scared to pronounce this figure, 20 trillion roubles," Putin told government ministers and top military officers.
   
"We need to finally overcome consequences of those years when army and navy were seriously underfinanced," Putin said at the navy shipyard SevMash in the northern town of Severodvinsk on the White Sea.
  
Putin said the modernisation programme will focus on strategic nuclear forces, air-defence systems, communication, intelligence, a fifth generation fighter plane and on the navy, which would receive about 4.7 trillion roubles.
   
Russia has been struggling for years to reform its armed forces, dogged by low morale and poor living conditions since the 1991 collapse of the Soviet Union. 


While Russia crushed Georgia in a five-day war in 2008, the short conflict exposed technical problems and ageing equipment.
  
Putin also launched the dock trial of Russia's second Borei class nuclear submarine, the Alexander Nevsky, designed to carry Russia's Bulava intercontinental missile.
   
Russia is completing the construction of three Borei-class nuclear submarines.
   
The first one, Yuri Dolgorikiy, is already undergoing sea trials, and is expected to go into service in the first half of 2011, said Deputy Prime Minister Sergei Ivanov. 

New Russian submarine to be commissioned in 2011

Russian Prime Minister Vladimir Putin Monday congratulated the dock trials of the Alexander Nevsky nuclear submarine in northern region of Severodvinsk, saying the submarine is due to enter service in Dec. 2011, Xinhua informed.

Alexander Reznikov, a new strategic missile-carrying submarine of the Borei class, is currently under construction at the Sevmash shipyard.

"The nuclear submarine is due to be handed over to the navy in 2011 if work goes at the set pace," Putin was quoted by local media as saying.

"It is precisely that this modern, quality equipment must be supplied to all our Armed Forces in the nearest future," he said.

In addition, Putin also told a meeting in Severodvinsk that Russian Armed Forces will receive over 1,300 types of weaponry in line with a draft arms procurement program until 2020.

"We will need to set up new or expand the existing production lines to manufacture 220 of the new types of weaponry," Putin was quoted by RIA Novosti news agency.

More than 20 trillion rubles (640.7 billion U.S. dollars) will be earmarked for weapons procurement, three times more than the sum allocated in the existing 2007-2015 program, he added.
