O problema parece ser o PA já em fase de construção. Modifica-lo para operar CatoBar sairia alguns bilhões de libras mais caro. Ou seja, o F-35C é mais barato de operar, mas manter um PA CatoBar é mais caro. E modificar um PA em construção para CatoBar é ainda mais caro. :)

The Jet That Ate the Pentagon: The F-35 Is A Boondoggle. It's Time to Throw It In the Trash Bin


(Source: Foreign Policy; published April 26, 2012)


By Winslow Wheeler



The United States is making a gigantic investment in the F-35 Joint Strike Fighter, billed by its advocates as the next -- by their count the fifth -- generation of air-to-air and air-to-ground combat aircraft. Claimed to be near invisible to radar and able to dominate any future battlefield, the F-35 will replace most of the air-combat aircraft in the inventories of the U.S. Air Force, Navy, Marine Corps, and at least nine foreign allies, and it will be in those inventories for the next 55 years. It's no secret, however, that the program -- the most expensive in American history -- is a calamity.

This month, we learned that the Pentagon has increased the price tag for the F-35 by another $289 million -- just the latest in a long string of cost increases -- and that the program is expected to account for a whopping 38 percent of Pentagon procurement for defense programs, assuming its cost will grow no more. Its many problems are acknowledged by its listing in proposals for Pentagon spending reductions by leaders from across the political spectrum, including Rep. Barney Frank (D-Mass.), Sen. Tom Coburn (R-Okla.), President Barack Obama's National Commission on Fiscal Responsibility and Reform, and budget gurus such as former Sen. Pete Domenici (R-N.M.) and Alice Rivlin, former director of the Congressional Budget Office and Office of Management and Budget.

How bad is it? A review of the F-35's cost, schedule, and performance -- three essential measures of any Pentagon program -- shows the problems are fundamental and still growing.

First, with regard to cost -- a particularly important factor in what politicians keep saying is an austere defense budget environment -- the F-35 is simply unaffordable. Although the plane was originally billed as a low-cost solution, major cost increases have plagued the program throughout the last decade. Last year, Pentagon leadership told Congress the acquisition price had increased another 16 percent, from $328.3 billion to $379.4 billion for the 2,457 aircraft to be bought. Not to worry, however -- they pledged to finally reverse the growth.

The result? This February, the price increased another 4 percent to $395.7 billion and then even further in April. Don't expect the cost overruns to end there: The test program is only 20 percent complete, the Government Accountability Office has reported, and the toughest tests are yet to come. Overall, the program's cost has grown 75 percent from its original 2001 estimate of $226.5 billion -- and that was for a larger buy of 2,866 aircraft.

Hundreds of F-35s will be built before 2019, when initial testing is complete. The additional cost to engineer modifications to fix the inevitable deficiencies that will be uncovered is unknown, but it is sure to exceed the $534 million already known from tests so far. The total program unit cost for each individual F-35, now at $161 million, is only a temporary plateau. Expect yet another increase in early 2013, when a new round of budget restrictions is sure to hit the Pentagon, and the F-35 will take more hits in the form of reducing the numbers to be bought, thereby increasing the unit cost of each plane.

A final note on expense: The F-35 will actually cost multiples of the $395.7 billion cited above. That is the current estimate only to acquire it, not the full life-cycle cost to operate it. The current appraisal for operations and support is $1.1 trillion -- making for a grand total of $1.5 trillion, or more than the annual GDP of Spain. And that estimate is wildly optimistic: It assumes the F-35 will only be 42 percent more expensive to operate than an F-16, but the F-35 is much more complex. The only other "fifth generation" aircraft, the F-22 from the same manufacturer, is in some respects less complex than the F-35, but in 2010, it cost 300 percent more to operate per hour than the F-16. To be very conservative, expect the F-35 to be twice the operating and support cost of the F-16.

Already unaffordable, the F-35's price is headed in one direction -- due north.

The F-35 isn't only expensive -- it's way behind schedule. The first plan was to have an initial bath of F-35s available for combat in 2010. Then first deployment was to be 2012. More recently, the military services have said the deployment date is "to be determined." A new target date of 2019 has been informally suggested in testimony -- almost 10 years late.

If the F-35's performance were spectacular, it might be worth the cost and wait. But it is not. Even if the aircraft lived up to its original specifications -- and it will not -- it would be a huge disappointment. The reason it is such a mediocrity also explains why it is unaffordable and, for years to come, unobtainable. (end of excerpt)

Aviação militar: decepção com quinta geração de caças
Na Voz da Rússia foi realizada uma mesa redonda dedicada ao 100º aniversário da Força Aérea da Rússia e às perspectivas de desenvolvimento da aviação militar e da indústria aeronáutica nacional.
A A A

No evento participaram peritos militares e industriais russos bem conhecidos. No processo de melhoria do equipamento técnico da Força Aérea Russa e de criação de novos tipos de aeronaves, os especialistas russos analisam de perto a experiência mundial nesta área. O tema das principais tendências na indústria aeronáutica mundial foi discutido por Ivan Kudishin, editor da revista semanal Equipamento de Aviação e Mísseis.

Na última década, o ramo de veículos aéreos não tripulados (VANT) desenvolveu-se enormemente. Se no início de 2000 se falava somente de veículos de reconhecimento e vigilância (de todas as classes – desde muito leves a pesados), hoje em dia a ênfase está mudando em favor de VANTs de reconhecimento e ataque.

Um exemplo notável é o concurso UCLASS da Marinha dos EUA para a construção de um VANT bombardeiro de ataque para porta-aviões. Os participantes do concurso são Northrop Grumman, a Boeing, a General Atomics e a Lockheed Martin. A criação de um VANT de convés é uma tarefa extremamente difícil: ele tem que pousar em um porta-aviões em movimento. A criação de VANTs descartáveis e reutilizáveis para uso com uma variedade de plataformas móveis, incluindo submarinos e aviões de patrulha, é hoje uma área chave no desenvolvimento deste tipo de equipamento.

Atualmente, foi reiniciado o desenvolvimento de uma plataforma de bombardeio e reconhecimento de nova geração, que irá substituir o material obsoleto (B-1B e B-52H), a partir de aproximadamente 2025. O avião deverá ser quase impercetível, subsônico, e, opcionalmente, tripulado. Isto significa que ele pode ser usado seja como VANT, seja como avião tripulado. O aparelho será equipado com uma vasta gama de armamentos de precisão e de baixa visibilidade.

Quanto aos aviões de quinta-geração, pode se dizer que a experiência de seu desenvolvimento nos EUA falhou. Um bom avião com grandes perspetivas de modernização e de expansão de suas capacidades militares, o Lockheed Martin F-22, foi construído em uma série muito pequena de 187 aviões, dos quais 2 se perderam em acidentes e um – em um desastre causado pela imperfeição do sistema de suporte de vida do piloto. Em serviço estão cerca de 160 aviões, dos quais apenas 55-65% estão prontos para combate.

O novo avião F-35, que está passando testes, sofre logo de duas doenças incuráveis: da excessiva universalidade e do crescimento descontrolado do custo. Apesar de sua aviônica avançada e de baixa visibilidade para os radares, o avião não possui velocidade de cruzeiro supersônica, tem capacidade de manobra e características dinâmicas limitadas, bem como uma modesta capacidade de carga.

Os programas das modificações de convés, F-35C e F-35B, estão sob ameaça de encerramento. O custo de um avião F-35A para exportação é hoje de 122,8 milhões de dólares (apesar de o avião ter sido inicialmente posicionado como um aparelho de produção em massa e de custo inferior a 60-70 milhões de dólares), e o custo do F-35B atinge 190 milhões de dólares.

Como alternativa, as empresas Boeing e Lockheed Martin oferecem profundas modificações de aeronaves existentes F-15, F-16 e F/A-18E/F, que possuem uma visibilidade significativamente baixa e capacidades de combate avançadas.

Atualmente continua a produção de aviões médios de transporte militar estratégico Boeing C-17. A linha de montagem não será reduzida ou fechada, portanto as perspetivas de fornecimentos para a Força Aérea dos EUA se mantêm.

Continua a produção em série do avião C-130J Super Hercules, que ainda tem um bom potencial de exportação. Mas já muito em breve ele terá que competir com o avião de transporte Embraer KC-390. A Força Aérea do Brasil deverá receber estes aviões em 2014. O custo do C-130 é de 67 milhões de dólares, o valor declarado do KC-390 é de 50 milhões de dólares.

Então se um F-35 for "descoberto" o bicho pode pegar, seria isso?

F-35 Debate: Canadian Firms Will Lose Out If Government Ditches Jets: Lockheed Martin (excerpt)


(Source: Postmedia News; posted May 24, 2012)



OTTAWA --- F-35 manufacturer Lockheed Martin is warning that Canadian companies will lose out if the Conservative government decides not to purchase the stealth fighter.

"Right now we will honour all existing contracts that we have," Lockheed Martin vice-president Steve O'Bryan told Postmedia News on Thursday. "After that, all F-35 work will be directed into countries that are buying the airplane."

But O'Bryan also said his company has not received any indication Canada won't buy the aircraft.

"What we have is the official statement out of the government and we're working with the government," he said. "They're committed to the F-35, they've selected it, and we haven't had any change in that official position."

That will likely come as a surprise to many Canadians as the Conservative government has said since last month that it has not committed to purchasing the F-35 and that all options are still on the table when it comes to replacing Canada's aging fleet of CF-18 fighters.

O'Bryan said Lockheed Martin is working on the understanding that it will begin producing Canada's first F-35s in 2014, with delivery by 2017. To do that, the company is looking to increase production capabilities now so it is ready to start work in time.
While O'Bryan acknowledged Canada's 65 F-35s will represent a fraction of the total number of stealth fighters produced in the coming years, he indicated Canada-specific investments are being made.

"We've received a commitment from the Canadian government," he said. (end of excerpt)

RNLAF: Reduction to 42 F-16s – Airbase Leeuwarden Closed (edited for style)


(Source: JSFnieuws.nl; issued May 29, 2012) :arrow: http://www.jsfnieuws.nl/

STIENS (FRL) --- The plans are ready: the Royal Netherlands Air Force is being reduced to only 42 F-16 fighter jets and the Main Operating Base Leeuwarden will soon lose its F-16 squadrons. The independent Dutch website JSFNieuws.nl on May 29 released a confidential plan that the government planned to keep secret until after the elections due in September 2012.


The plan is of course “confidential” and distributed in a very small circle of trusted people and politicians. Publicity surrounding the plan would be subject to very precise timing, because the intention was to keep it strictly silent until after the forthcoming elections.

Selected scenario: down to 42 F-16

In late 2011 new financial data about the price, operating and support costs, and concurrency modification costs was made available to the Dutch government by the United States. Initially, the data was reviewed by the Project Team Replacement F-16 (PV F-16) and, subsequently, at a higher level. It quickly became apparent that Dutch aviation planning assumptions had to be recalculated in light of the new data.

The PV F-16 team was tasked with the preparation of various scenarios, with two Main Operating Bases (MOB), at Volkel and Leeuwarden; with 1 MOB (either Volkel or Leeuwarden), or 1 MOB with a reserve base.

All kinds of data was involved, such as numbers, flight hours, training scenarios, collaboration, numbers of people, basic maintenance, re-use of airbase area, noise and environmental effects, etc.

The final scenario with the most potential for savings within given optimal operational capabilities and financial parameters:
- Reduction of the number of fighter aircraft F-16 from 68 to 42
- Closing of 1 airbase, near Leeuwarden,
- Realization between 2014 and 2016

Cause: the arrival of the F-35

It is remarkable that the arrival of the F-35, which should have ensured the future of the Royal Netherlands Air Force for the coming decades, is being put forward as the main reason for this huge reduction:

“Calculations show that, due to the budget of € 4.5 billion for replacement of the F-16s, the RNLAF only has sufficient funds to procure 42 F-35A fighter aircraft.”


The MOD paper also states that,for this reason it is better and cheaper to anticipate the reduction of the size of the RNLAF by reducing, as soon as possible, the number of F-16s in service to 42. This would reduce the requirement to a single air base, allowing one main operating base to be closed down with significant savings.

Other quote: “The replacement of the F-16 is a major financial risk for the Defense budget if we would select the Lockheed F-35A, not only because of rising investment costs but also because of high operating costs.”

However, the MoD’s document states that “It is clear: because of the investments already made, it is notan option to abandon the JSF. Cancellation has not even been considered in the current calculations”.

Keeping quiet until after election

Why should this remain silent? And why all who were involved in making these plans and others, politically-involved persons, were told to keep these plans confidential?

Clearly, there are two reasons: firstly, the total dismantling of the Royal Netherlands Air Force will meet huge resistance among the voters of the conservative-liberal VVD and conservative-christian party CDA.

But, because it also appears from the documents that the main cause of the dismantling is the high price and unaffordability of the F-35s, this will cause debate.

A confrontation of the failure of the F-35 project is not welcome for the ruling and responsible parties VVD and CDA in the coming election period. They don’t like having too much focus on the JSF and replacement of the F-16 in the run-up to the election, during election debates and (inevitably) in the subsequent coalition talks. Therefore bad news had to be kept under the proverbial hat.

Now that the plan has been leaked and published, the political elite will first try to get away with claiming that this is only speculation by JSFNieuws, with no foundation in fact, or that it is “just a calculation,” while the Ministry of Defence will reiterate its habitual statements that the decision to buy the F-35 “falls in next cabinet period,”and will be taken by the next government.

However, the facts - on paper - tell a different story. And the top-level persons involved in the policies for the VVD and CDA parties are aware of the various necessary trade-offs that will be required for the replacement of the F-16s.

Increasingly clear since 2005 …….

It has long been clear, within the top echelons of the Dutch MoD, that it is impossible, withthe current budget earmarked for replacement of the F-16, to purchase the 85 F-35A JSF Lightning II aircraft as originally planned.

This was already clear in 2005, documents show, and it has been published as early as 2009 by JSFNieuws.

On 22 August 2005, the outgoing US ambassador (Sobel) to the Netherlands wrote his opinion of the Netherlands, some important aspects of Dutch policy, and how to the US should deal with it. His message read:

“Their desire to maximize the military’s capabilities and their preference for US equipment, even when alternative European suppliers exist, make the Dutch strong supporters of the Joint Strike Fighter (JSF) program. (…) Dick Berlijn is pushing to lock in an early commitment for 50 planes (out of a total of 85) to prevent JSF from becoming an issue in the 2007 elections.”

By splitting the purchase in a first batch of 50 aircraft, followed by a hypothetical second batch, the idea was to push into the future the painful realization that the Netherlands could only afford a much smaller number of fighter aircraft.

With the repeated delays and price increases over the last couple of years, it became clear that even a number of around 60 aircraft would be impossible and unaffordable. The real outcome is known at this moment: 42 F-35A’s or less.

Thanks

JSFNieuws is able to publish thisinformation thanks to someone who has taken the responsibility to make public documents that were being kept secret siply to avoid political embarrassment.

Since 2008 our website has been able to publish several report, based on data from various countries, which was kept hidden for political reasons.

Fortunately there are people who are prepared to help us in making public the reality behind political manipulation, and to expose it to the outside world. Most of time, these dedicated citizens only act after much doubt, and risk their jobs, and then only because they are not heard or ignored internally. We encourage people in other countries to do the same.
