O que realmente matou a idéia inicial, foi o assustador aumento no custo do F-35...

E que fique um alerta para os defensores do gripen NG...

Imaginemos que 50 aeronaves são mais que suficientes para apenas 1 PA.

Esta claro que a Inglaterra vai trocar quantidade por qualidade... E isto me parece ser cada vez mais importante...

Espero que aos poucos o Brasil e outras nações possam rivalizar forças com estes tradicionais países, como França e Reino Unido.

Navy's fleet set to shrink further says fresh study



14 January 2010
By Matt Jackson
Defence correspondent
Defence experts have predicted the navy will find it 'incredibly tough' to replace ships as government spending shrinks.
Budget cuts and the growing cost of defence assets were two main factors mentioned in a report predicting a drop in the size of the armed forces.

But for workers in The News area the squeeze is also expected to mean reductions to future shipbuilding programmes.

The report said that if the cutbacks were evenly spread major vessels would drop from 57 to 46.

Portsmouth South MP Mike Hancock, who sits on the Commons defence committee, said: 'The navy will find the next five years even tougher than the pressure they've been under so far.

'The navy has had to fight and play very carefully to get the two carriers, and there really isn't any slack in the budget for them to push for more.

'I heard evidence at the defence committee this week and the tone was incredibly downbeat.

'It's clear that the army will be favourites to get any funding because of Afghanistan, but at least the navy is in a better position than the air force.

'I think there could be a radical rethink of the future of the RAF.'

Yesterday's report by the respected Royal United Services Institute found personnel levels would be impossible to preserve in the face of a rising budget deficit.

Professor Malcolm Chalmers, who wrote the report, said personnel levels could fall from 175,000 in 2010 to 142,000 in 2016.

He said: 'Projected reductions in budgets and personnel will require large reductions in the number of front-line capabilities.'

The report was based on data from the Ministry of Defence, HM Treasury, the National Audit Office and political parties, through an analysis of budget projections.

It came a day after the MoD admitted 20 per cent of Britain's infantry is unfit to fight on the front line.

Commander John Muxworthy, head of the UK National Defence Association said: 'The Rusi report is absolutely full of doom and gloom and if the navy was cut to the levels predicted it would be an utter disaster.

'We seem to forget in this country that all of our institutions are built on the safety that our defence spending provides, and taking it away will leave us at real risk.'

Royal Navy Ready to Help Stranded Britons


(Source: UK Ministry of Defence; issued April 19, 2010)



The Government has announced plans to help repatriate Britons stranded overseas following the grounding of air traffic over much of Europe last Thursday.

Royal Navy ships HMS Ark Royal and HMS Ocean have been deployed to the Channel to help with the relief effort, and HMS Albion is sailing to northern Spain to pick up UK Service personnel returning from Operation HERRICK in Afghanistan.

We will also be working with the Spanish authorities to use their airports, which are currently outside the volcanic ash zone, as a hub to repatriate British travellers.

The Prime Minister has been discussing options with the Spanish Prime Minister, Jose Zapatero, and Head of the European Commission, President Barroso, and later today EU Transport Ministers will be holding a video conference.

The PM said the Government's 'paramount concern' was the safety of air passengers:

"Today we are looking at the results of test flights that have been up in the air yesterday and today and looking also at the manufacturers' recommendations, but that will be dealt with by the European Council meeting of Transport Ministers that will be held by video link later this afternoon and further decisions about when flights can go and whether flights cannot go will have to be made as a result of the conclusions of these meetings."

The Government also said that it was working with travel operators to ensure that ferries and Eurostar are at a higher capacity to maximise the number of people they can bring home.

The Foreign Office will ensure that consular staff are available to help and assist. This includes visiting airports, working with the local authorities to resolve visa problems and advising British nationals who have run out of funds.

They have launched a special advice line for callers in the UK who are concerned about the well-being of relatives stranded overseas. The number is 020 7008 0000.

An MOD spokesman said:

"Following this morning's COBRA meeting and the Prime Minister's statement, the Ministry of Defence is looking at how a number of Royal Navy vessels could provide support to UK Government efforts to assist British travellers stranded abroad and wishing to return home to the UK.

"We are urgently looking into the detail of how this support will work in practice but as part of the preparations we are looking at how the RN will be employed to provide assistance to the Government's wider efforts.

"HMS Albion is expected to arrive in Santander tomorrow morning where its primary role will be to collect UK Service personnel who have recently left the ongoing operation in Afghanistan. HMS Ocean is currently in southern British waters and is standing by for tasking. HMS Ark Royal, who was deployed on exercise off the north west coast of Scotland, is sailing south to provide further assistance as required.

"We are supporting detailed cross-Government planning to confirm how best we can assist."

Flights have been grounded due to the presence of a large amount of volcanic ash in the atmosphere from a volcano erupting in Iceland.

Nuclear Submarines Went to Sea with Potentially Disastrous Defect (Excerpt)


(Source: The Guardian; published May 2, 2010)



Two British nuclear submarines went to sea with a potentially disastrous safety problem that left both vessels at risk of a catastrophic accident, the Guardian can reveal.

Safety valves designed to release pressure from steam generators in an emergency were completely sealed off when the nuclear hunter killers Turbulent and Tireless left port, a leaked memo discloses.

The problem went undetected on HMS Turbulent for more than two years, during which time the vessel was on operations around the Atlantic, and visited Bergen in Norway, the Portuguese capital, Lisbon, and Faslane naval base near Glasgow.

It was not noticed on HMS Tireless for more than a year, and was finally detected last month, two months after Tireless started sea trials from its home port at Devonport naval base in Plymouth.

Tireless was involved in another serious incident in 2007, when two submariners were killed in an onboard explosion in air purification equipment. In 2000, it was stranded in Gibraltar for nearly a year after a leak from pipework leading from its reactor, putting immense strain on British relations with Spain.

The Ministry of Defence memo, which was written last week, admits that both cases involving the sealed-off valves were "a serious incident" that raised major questions about "weak and ambiguous" safety procedures at Devonport dockyard and within the Royal Navy.

The blocked valves, on the hull of the submarines, meant that steam from nuclear-powered boilers could not have been released in an emergency, leading to a potentially disastrous build-up of pressure.

John Large, a consultant on nuclear safety who advises governments on submarine safety, said: "It was a very significant failure. These two submarines were unfit for service. It was a perilous situation."

He said sealing these valves was like blocking the valve on a domestic pressure cooker. If pressure had built up to dangerous levels, the submarine's steam circuit could have burst, leaking radioactivity into the submarine and shutting down the reactor. "There would be a risk of fatalities," Large said. "This was such a glaring and fundamental omission. It's jaw-dropping." (end of excerpt)

UK's most powerful submarine joins the Navy



27 Aug 10

The UK's most powerful attack submarine, HMS Astute, has been welcomed into the Royal Navy today in a commissioning ceremony overseen by the boat's patron, the Duchess of Cornwall.

HMS Astute, which officially becomes 'Her Majesty's Submarine' today, is quieter than any of her predecessors, meaning she has the ability to operate covertly and remain undetected in almost all circumstances despite being fifty per cent bigger than any attack submarine in the Royal Navy's current fleet.

The latest nuclear-powered technology means she will never need to be refuelled and can circumnavigate the world submerged, manufacturing the crew's oxygen from seawater as she goes.

The submarine has the capacity to carry a mix of up to 38 Spearfish heavyweight torpedoes and Tomahawk land-attack cruise missiles, and can target enemy submarines, surface ships and land targets with pinpoint accuracy, while her world-beating sonar system has a range of 3,000 nautical miles (5,500km).
The First Sea Lord, Admiral Sir Mark Stanhope, said:
[INDENT]"The Astute Class is truly next generation - a highly versatile platform, she is capable of contributing across a broad spectrum of maritime operations around the globe, and will play an important role in delivering the fighting power of the Royal Navy for decades to come.
[/INDENT]

[INDENT]"A highly complex feat of naval engineering, she is at the very cutting-edge of technology, with a suite of sensors and weapons required to pack a powerful punch.
"Today is an important milestone along the road to full operational capability which will follow after a further series of demanding seagoing trials testing the full range of the submarine's capabilities."
[/INDENT]Following the successful completion of her first rigorous set of sea trials, which began at the end of 2009, HMS Astute has also now achieved her in-service date, signalling that she has proven her ability to dive, surface and operate across the full range of depth and speed independently of other assets, thereby providing an initial level of capability.

Rear Admiral Simon Lister, Director of Submarines, who oversees the build programme of the class for the MOD, said:
[INDENT]"To my mind Astute is a 7,000-tonne Swiss watch. There is an extraordinary amount of expertise that goes into putting one of these submarines together. There are stages when it's like blacksmithing and there are stages when it's like brain surgery.
"So to see Astute commissioned is momentous not only for the Royal Navy, who have been eagerly anticipating this quantum leap forward in capability, but for the thousands of people around the country who have been involved in the most challenging of engineering projects."
[/INDENT]

Following the commissioning, HMS Astute will return to sea for further trials before she is declared as operational.

As the base port of all the Royal Navy's submarines from 2016, Faslane will be home to the whole Astute Class, including Ambush, Artful and Audacious which are already under construction.

Astute was built by BAE Systems at Barrow-in-Furness, with hundreds of suppliers around the country contributing component parts, including Rolls-Royce, Derby (nuclear plant); Thales UK, Bristol (visual system and Sonar 2076); and Babcock, Strachan & Henshaw, Bristol (weapon handling and discharge system). Astute is affiliated to the Wirral in the North West.

About HMS Astute

• She is 97 metres from bow to stern.
• She has a beam of 11.2 metres.
• She displaces 7,400 tonnes of seawater.
• Her cabling and pipework would stretch from Glasgow to Dundee.
• She is the first Royal Navy submarine not to have a traditional periscope, instead using electro-optics to capture a 360-degree image of the surface for subsequent analysis by the commanding officer.
• Astute is the first submarine to have an individual bunk for each crew member.
• She manufactures her own oxygen from seawater as well as her own drinking water.
• She could theoretically remain submerged for her 25-year life, if it were not for the need to restock the crew's food supplies.
• She is faster under the water than she is on the surface - capable of speeds in excess of 20 knots (37km/h), although her top speed is classified.
• Astute's crew of 98 are fed by five chefs who, on an average patrol, will serve up 18,000 sausages and 4,200 weetabix for breakfast.
