Também duvido muito que cancelem o programa como um todo, já se envolveram demais nele para isso ser possível.

Por outro lado existe sim a possibilidade de acabarem cancelando um monte de requerimentos e simplificando o projeto a tal ponto que o resultado não será o avião omnirole que se esperava no início e sim algo especializado em alguma tarefa específica que aproveite aquilo que ele pode fazer. Ao invés de vir a ser o F-16 do século XXI pode acabar como o F-111, cumprindo apenas uma das muitas tarefas inicialmente imaginadas. Talvez venha a ser apenas um substituto do F-117, com umas poucas unidades produzidas. Só não quero nem ver onde vão parar os custos por aparelho se isso realmente vier a acontecer.

De qualquer forma o texto me pareceu meio tendencioso, alguns dos problemas citados (como as falhas eletrônicas) não devem ser assim nada absurdo para resolver. E as limitações de performance provavelmente não tem a ver com restrições da célula em si, mas apenas com a falta de alguns testes que devem estar atrasados. Vamos aguardar mais um pouco para ver o que sai deste mato. Mas de qualquer forma o programa não parece primar pela boa sorte.

Provavelmente eles não devem estar conseguindo alcançar algums dos parametros exigidos em contrato.
O que não significa que a aeronave seja ruim, mas que certamente inviabiliza a aceitação nos termos atuais.

O problema do F-35 é quererem tudo em um caça só, eles quererem um "Anderson Silva" e podem ganhar um "Chael Sonnen": fala, fala, mas na hora do "vamos ver"...

Temos mais 15 anos com os F-16 sem problema. E porquê? Porque no MLU que sofreram em Portugal reforçou-se a estrutura, melhorou-se o hardware e o software e as actualizações não param. Começou-se o programa com a versão MLU/M3 e já vamos no M5.

O futuro só Deus é que sabe, mas para mim o F-35 não vem para Portugal.

F-35 Lightning II News

All 51 F-35s cleared to resume flight operations
http://www.f-16.net/news_article4705.html

March 1, 2013 (by Lieven Dewitte) - The Pentagon will resume flights of its F-35 Joint Strike Fighter jets, which were grounded a week ago after a crack was discovered in a low-pressure turbine blade of an engine in one F-35 at Edwards AFB.


The Pentagon's F-35 program office decided to lift a temporary suspension of flight operations after it conducted extensive tests on the affected engine part. All 51 planes have been cleared to resume flight operations.

It was determined that prolonged exposure to high levels of heat and other unspecific "stressors" were determined to be the cause of the 0.6 inch crack rather than a design flaw. No additional cracks were found during inspections of engines on the remaining 50 planes in the Pentagon's fleet, or any spare engines, Pentagon spokeswoman Kyra Hawn said in a statement.

Pratt, a unit of United Technologies Corp that supplies the engines, had been working around the clock with Pentagon officials to determine the cause of the crack in the engine blade.

Matthew Bates, a spokesman for engine manufacturer Pratt & Whitney said the engine in question had operated at high temperatures more than four times longer than a typical F-35 flight, which led to a separation of the "grain boundary" of this particular blade.

"The engine in question was part of the F-35 test aircraft fleet and had been operated for extended time in the high-temperature environment in its mission to expand the F-35 flight envelope." Joe DellaVedova, a spokesman for Program Office said.

The Pentagon announced the grounding of all F-35 warplanes almost a week ago after an inspection revealed a crack on a turbine blade in the jet engine of an F-35 being tested at Edwards Air Force Base in California.

It was the second engine-related grounding in two months of the F-35 Joint Strike Fighter, the Pentagon's largest weapons program which costs nearly $400bn.

The Marine Corps variant (F-35B), a short take-off and vertical landing variant (STOVL), was grounded for nearly a month after a manufacturing defect caused a fuel line to detach just before a training flight in January.

Exclusive: Retrofits to add $1.7 billion to cost of F-35 - GAO report



By Andrea Shalal-Esa

WASHINGTON | Sat Mar 9, 2013 7:14pm EST

(Reuters) - Retrofits of F-35 fighter planes to fix problems found in flight testing will likely top $1.7 billion, a U.S. government watchdog said in the draft of a new report about the Pentagon's Joint Strike Fighter program.

Extensive restructuring efforts and progress on technical issues have put the Lockheed Martin Corp F-35 program on a more solid footing, but the plane's long-term affordability remains a big concern, the Government Accountability Office said in the draft, a copy of which was obtained by Reuters.

It said the F-35 program, which has been subject to massive delays and cost overruns and now has a price tag close to $400 billion, met most of its management objectives in 2012. But it still faced big costs because of earlier decisions to start building planes before development and testing were further along. A final report is due out next week.

The F-35 is an advanced "fifth generation" fighter meant to serve the U.S. Air Force, Navy and Marines for decades to come. But the program's soaring costs and technical complications have now put it in a critical position, where any new setbacks or cuts in orders from the U.S. military and its allies would drive the cost-per-plane up still further.

The GAO draft report offers the agency's most positive outlook yet for the Pentagon's most expensive weapons program, which has seen a spate of negative news in recent weeks, including two engine-related groundings this year.

But it also underscores concerns about the long-term future of the program given budget reductions in the United States and other countries that plan to buy the radar-evading warplane.

"Overall, the F-35 Joint Strike Fighter program is now moving in the right direction after a long, expensive and arduous learning process," GAO said. "Going forward, ensuring affordability - the ability to acquire aircraft in quantity and to sustain aircraft going over the life cycle - is of paramount concern."

No comment was immediately available from the Pentagon's F-35 program office or Lockheed.

The program faces substantial costs to retrofit planes to address problems discovered in flight testing, GAO said.

Such "rework" would add $900 million to the cost of the first four batches of jets build by Lockheed, GAO said, plus about $827 million over the next six batches for a total of $1.7 billion.

Last June, GAO had forecast rework costs of $373 million for the first four batches of jets, but gave no estimate for the remaining batches.

Lockheed agreed in its contract for a fifth batch of jets to pay for 55 percent of any cost overruns up to a certain ceiling, and all cost overruns beyond that. Retrofit costs are now shared equally by the Pentagon and the contractor.

COST OVERRUNS SEEN REACHING $1.2 BLN

GAO said cost overruns on 63 planes built by Lockheed in the first four production batches were now expected to reach $1.2 billion, of which the government will have to pay about $756 million. That marks an increase from GAO's last estimate in June 2012, which forecast a cost overrun of $1.04 billion.

Lockheed is building 58 planes for the U.S. military under those first four production contracts, plus five for international partners who helped fund the plane's development.

The report said cost overruns were declining as production costs were coming down, and Lockheed was delivering jets faster. Lockheed signed a contract with the Pentagon at the end of December for a fifth batch of planes, and both sides hope to reach a deal for the sixth and seventh batches this summer.

The GAO report reiterated the agency's concerns about the long-term procurement and sustainment cost of the F-35. It said current plans would require the Pentagon to spend $10.6 billion each year through 2037 on the program, putting "an unprecedented demand on the defense procurement budget."

It said the cost of each plane would rise if the Pentagon cut its plans to buy 2,443 F-35s or the eight foreign partners - Britain, Italy, Australia, Canada, Norway, Turkey, Denmark and the Netherlands - reduced their plans to buy 697 aircraft.

Industry executives and military officials say U.S. moves to defer orders for 410 aircraft in recent years have already jacked up the cost per plane, and costs will rise further unless Congress averts $500 billion in mandatory defense spending cuts slated to take effect over the next decade. Those cuts began to roll in last week.

GAO said the Pentagon's Cost Analysis and Program Evaluation office had calculated that the average cost of the plane, which has already nearly doubled to $137 million from $69 million originally estimated, would rise by 6 percent if all 697 foreign orders vanished.

The cost would rise by 9 percent if Washington only bought 1,500 jets and the partners stuck to their orders. But it would surge 19 percent if Washington bought 1,500 jets and the partners bought none, according to the GAO report.

Dinamarca tb a querer saltar do barco:
Denmark: Second JSF Partner Country Begins New Fighter Evaluation


(Source: adapted from JSFNieuws.nl; published March 14, 2013)



COPENHAGEN, DK --- With an official press release, the Danish Ministry of Defence has confirmed rumors that it has started a new competition to select a fighter aircraft to replace the Danish Air Force’s fleet of F-16s.

The evaluation is part of the Danish multi-year planning for 2013-2017, and it is intended to prepare a final political decision on the new fighter in June 2015.

Denmark is a JSF partner country (development contribution in 2002), but will hold an open competition. It is the second country to re-evaluate an earlier decision in favor of the Joint Strike Fighter. In December 2012 Canada also decided to hold a new and open competition and cancelled the sole-source decision (2010) to procure the F-35 after a very critical report by the Parliamentary Budget Officer and another by KPMG.

The competition was frozen in April 2010, but Boeing, Eurofighter, Lockheed Martin and Saab all received an official letter on March 13, 2013 informing them that the Danish MoD had resumed the purchase process for new fighters.

Dassault Aviation has not been invited to compete, and will not attempt to do so, company chief executive Eric Trappier told defense-aerospace.com after the company’s March 14 press conference in Paris. He said that the European partners are the least likely to withdraw from the Joint Strike Fighter program. He added that this explains why Dassault did not re-compete in the Netherlands, which he said had made a lot of noise about holding a new competition but had ultimately stayed with the JSF. “It probably allowed them to obtain a better price from the Americans,” he said.

Last autumn some preparations were made by visiting US manufacturer Boeing and the JSF Program Office.

Remarkable is the confirmation that the Eurofighter Typhoon has been invited to re-enter the bidding process, after leaving it in 2007. Eurofighter withdrew in December 2007 from the Danish and Norwegian competitions, as it believed that both “competitions” were skewed in favor of the F-35 Joint Strike Fighter.

Current Fleet

The Royal Danish Air Force (RDAF or Kongelige Danske Flyvevåben) has one main operating base located at Skrydstrup, with one fighter wing with two multi-role frontline squadrons (Esk 727 and Esk 730). A total of only 30 Lockheed Martin F-16AM/BM is still operational.

Most of the two-seat 16BM are operated by Esk (Sqd) 727 in its training role, while Esk (Sqd) 730 contributes to the NATO Rapid Reaction Force. The RDAF’s last operation was during the military intervention in Libya in 2011 when six Danish F-16s operated from Sigonella in Italy. In 2004, 2009 and 2010 the RDAF contributed to the NATO Baltic Air Policing operation in Lithuania.

In the 1960s and 1970s the RDAF operated a number of US-financed Lockheed F-104G Starfighters, North American F-100D and F-100F Super Sabres, and a fleet of Saab Draken fighter aircraft.

Low Operating and Support Costs Important

The Danish Parliament knows a decision will have huge influence on the defence procurement budget for nearly a decade. The operating and support cost will also affect the entire defense budget over the next 30-40 years. Therefore, low long-term operating and support costs are of critical importance for Denmark.

Comeback of Eurofighter Typhoon

The comeback of Eurofighter is the most interesting aspect of the Danish decision. It could well prove a relatively strong candidate, because it is used by close NATO allies Germany and Britain. Also Germany is a very important trading partner and the most important country for Danish exports.

There is some speculation about a possibility for Denmark to buying Tranche 3B Eurofighters destined for the German air force, or buying used Eurofighters Tranche 1 or 2 versions from Germany, so that Germany can upgrade to the new Tranche 3b version. There were no legal or evaluation conditions that could give objections to a comeback of Eurofighter in the competition.

Evaluation process

Other candidates are the F-35 from Lockheed Martin; the Boeing Super Hornet and Saab’s Gripen Next Generation (now designated Gripen E). There is requirement for 24 to 32 fighter aircraft, depending on price and budget.

The new evaluation process and final recommendation will be ready at the end of 2014. Final political decision has to be taken around June 2015. (ends)
