Russia delays construction of 4th Borey-class nuclear sub


The start of construction of Russia's fourth Borey-class nuclear-powered submarine has been postponed from December to the first quarter of next year, a Defense Ministry official said on Tuesday.
Construction of the Project 955 Svyatitel Nikolai (St. Nicholas) ballistic-missile submarine was to begin on December 22 at the Sevmash shipyard in the northern Russian city of Severodvinsk.
The keel-laying ceremony was timed to coincide with the shipyard's 70th anniversary.
The official, who requested anonymity, stressed that the project was not being "frozen" but simply delayed for "organizational and technical reasons."
He did not specify the reasons.
Russia's newest Borey-class strategic nuclear submarine, the Yury Dolgoruky, which is expected to be armed with the new Bulava sea-launched ballistic missiles (SLBM), is currently undergoing sea trials.
The vessel is 170 meters (580 feet) long, has a hull diameter of 13 meters (42 feet), a crew of 107, including 55 officers, a maximum depth of 450 meters (about 1,500 feet) and a submerged speed of about 29 knots. It can carry up to 16 ballistic missiles and torpedoes.
Construction costs totaled some $713 mln, including $280 mln for research and development.
Two other Borey-class nuclear submarines, the Alexander Nevsky and the Vladimir Monomakh, are in different stages of completion. Russia is planning to build eight of these subs by 2015.
Fourth-generation Borey-class nuclear-powered submarines are expected to constitute the core of Russia's modern strategic submarine fleet.
However, the submarine's putting into service could be delayed by a series of setbacks in the development of the troubled Bulava missile, which has officially suffered seven failures in 12 tests.
However, some analysts suggest that in reality the number of failures was considerably larger. For example, according to Russian military expert Pavel Felgenhauer, of the Bulava's 12 test launches, only one was quite successful.
The future development of the Bulava has been questioned by some lawmakers and defense industry officials, who have suggested that all efforts should be focused on the existing Sineva SLBM.
But the Russian military has insisted that there is no alternative to the Bulava and pledged to continue testing the missile until it is ready to be put in service with the Navy.
Borey-class submarines have been exclusively designed for the Bulava, and redesigning them for the Sineva would be a major setback for the Navy's plans. (Original News)

Brazilian president committed to refurbishment of Armed Forces

Brazil's President Luiz Inacio Lula da Silva reiterated his administration's commitment to the refurbishment of the country's Armed Forces on Monday.

In a ceremony presenting the country's new generals in Brasilia, the president said the army received a shipment of 34 combat vehicles last week, the first of many of this kind.

"Until 2030, there will be 3,000 combat vehicles," he said.

President Lula also commented on the purchase of 36 fighter jets, which have been under negotiation. According to Lula, the government's final decision on the jet procurement would be announced in early January next year. The jets involved in the negotiation are France's Rafale, the United States' F-18 and Sweden's Gripen NG.

Additionally, President Lula stressed the importance of the nuclear submarine to the country. The submarine will be built in Brazil under an agreement signed with France, which was announced earlier this year.
    
The president also said that Brazil's Armed Forces need to be recognized for their roles in programs such as the Minustah, the UN's mission in Haiti, in the fight against dengue fever in the northeastern state of Bahia, and in the support they provide to airmail services and hospitals in the Amazon rainforest region.

Trident Program Intent On Avoiding Past Shipbuilding Pitfalls


As the Navy begins to design its next ballistic-missile submarine, officials caution that the service must avoid shipbuilding practices of the past that have led to cost overruns and delays.

 Although the first of the Navy’s fleet of ballistic missile submarines won’t retire for another 17 years, the time to start the design work is now, said Vice Adm. Jay Donnelly. “This is the right time for the Navy to commence efforts to replace the Ohio-class SSBN. It’s not too early,” said Donnelly, who is the commander of the Navy’s submarine force.

The oldest of the nuclear-powered submarines have reached the mid-point of their service lives and are expected to remain in service for at least another 20 years. Although the Defense Department already has approved funding for the new submarine, Navy officials are under pressure to get the program on the right track in order to ensure long-term support for the program.

“We must start this work in earnest now in order to avoid a gap” and to sustain the industrial base, said Rear Adm. Cecil Haney, director of the submarine warfare division in the office of the chief of naval operations.

It takes an average of 20 years to design and build a new-generation submarine. “Anything as complex as a submarine takes time to get it right, and then to allow us to utilize it for 42 years,” he said at the Naval Submarine League’s annual symposium in McLean, Va.

RAF's Nimrod plane fleet withdrawn in defence cuts


A Nimrod MR2 surveillance plane

The RAF’s fleet of 11 Nimrod surveillance aircraft, one of which catastrophically burst into flames killing 14 servicemen in Afghanistan in 2006, is to be withdrawn from service by March next year as part of a range of defence cuts announced today.

Bob Ainsworth, the Defence Secretary, denied that the decision to axe the Nimrod Mark 2s 12 months earlier than planned had anything to do with the crash of Nimrod XV230, which was caused by leaking fuel, and he insisted it was still safe to fly. He told the Commons the decision was purely for financial reasons.

He said the decision was unconnected to the devastatingly critical official report published in October by Charles Haddon-Cave QC, who accused the Ministry of Defence of sacrificing safety to save money on maintenance of the Nimrod fleet. Several senior military officers were criticised in his report.

However, Mr Ainsworth also announced that the programme to introduce a replacement, the Nimrod MRA4, was going to be delayed. With the Mark 2s scrapped by the end of March, this will leave a capability gap, defence sources confirmed.

The first MRA4 - one of nine ordered - will be delivered to RAF Kinloss in Morayshire - home of the Nimrods - in February but it will not be operational for a long time because the crews will have to carry out lengthy flight training. “It’s a brand new aircraft, so it will take time,” a defence official said.
One of the principal roles of the Nimrod anti-submarine-warfare and surveillance aircraft is to protect Britain’s nuclear ballistic-missile submarine deterrent as it leaves Faslane on the Clyde for patrols in the North Atlantic and Antarctic.

The defence sources said that the protection of the deterrent would have to be left in the hands of the Royal Navy, using hunter-killer nuclear-powered submarines.

The decision on the Nimrod Mark 2s and its replacement will have a considerable impact on the personnel at RAF Kinloss. There are currently 1,600 RAF staff based there, and a proportion of them, especially the engineers, will be displaced to other bases to work on different aircraft.

RAF sources said there were no plans to make any of the Kinloss staff redundant.
Although Mr Ainsworth emphasised that the thrust of the “savings” would be to provide more funds - £900 million - for Afghanistan, the switching of resources will mean that the defence support services will suffer.

The RAF will lose one Harrier squadron and probably a Tornado GR4 squadron although the latter's axeing will be delayed until next year’s strategic defence review. Four of the five Harrier squadrons are based at RAF Cottesmore in Leicestershire, a legendary wartime airfield, and this location is now earmarked for closure. The remaining Harriers will be based at RAF Wittering in Cambridgeshire.

The MoD has not ruled out RAF redundancies, although initially cutbacks will be achieved through natural wastage and a slowing of recruiting. Future redundancies are likely to fall on the staff based at Cottesmore. The base opened in 1938 and early bombing raids were carried out against German troops advancing through Belgium and France.

Andrew Brookes, director of the Air League, warned today that the MoD was once again engaged in trying to save money in the short-term but could expect greater costs in the long term. He said axeing Harriers and Tornados would not save money because they were worth nothing, and delaying the Nimrod MRA4 would add to the spiralling costs of the programme.

This week, the National Audit Office took the MoD to task for making a short-term saving of £450 million on the new Queen Elizabeth class aircraft carrier project by delaying the building programme - only to find that in the long term the cost would rise by £674 million.

The extra money for the frontline will come out of the MoD’s budget instead of Treasury reserves which normally finance operations in Afghanistan, because the new orders for - among other things - more Reaper unmanned spy planes, better body armour and more night-vision goggles and improved communications for special forces are intended to be long-term capability improvements.

Mr Ainsworth also confirmed the planned purchase of 22 more Chinook helicopters and another C17 Globemaster transport aircraft for the RAF. However, the first ten Chinooks will not be ready for operational service for another three or four years, by which time the British combat mission in Afghanistan could be winding down.

Liam Fox, Shadow Defence Secretary, said: “Our defences are being cut, not as a response to a diminished threat – if anything the threat is increasing. The Government that’s had four defence secretaries in four years, one of them part-time, is now cutting capability as a result of catastrophic economic mismanagement. Our brave Armed Forces are paying for Labour’s incompetence.”
“The new Chinook helicopters are of course welcome, but this decision would not have been necessary if the Prime Minister had not, against all advice, cut £1.4 billion from the helicopter programme in 2004,” Dr Fox said.

“But for his failure to understand the Armed Forces, those Chinooks could have been on the frontline today, saving the lives of our brave soldiers. Instead, they will not be available until at least 2013 by which time, according to the Prime Minister, we should have substantially transferred security responsibility to Afghan national forces.” (@timesonline)

GLINT in the eye: NURC explores novel autonomous concepts for future ASW

The La Spezia-based NATO Undersea Research Centre (NURC) has completed a major trial, known as GLINT09 (Generic Littoral Interoperable Network Technology), to investigate the exploitation of autonomous unmanned vehicles (AUVs) as part of a future anti-submarine warfare (ASW) operational construct.

NURC's Ocean Explorer, used as the primary data collecting platform and behaviour demonstrator for the GLINT09 experiment, was configured with a multiple octave BENS towed array and the TOSSA onboard source. (NURC)

The experiment, conducted in mid-2009, is judged to have been an important step towards the long-term goal of a fully functioning collaborative ASW system. NURC is planning to conduct a networked wide-area system demonstration in the 2011-12 timeframe, with the expectation that a deployable capability could be operational in the period 2020-25.
