Bota um Typhoon ou um Gripen ou um F-18 ou mesmo um Rafale para fazer o mesmo e ai conversamos se nao vale ou nao

Eu referia-me ao VTOL, só nessa configuração é possível, o F-35 é STOVL.

No contexto actual só estou a ver Israel a precisar dele e mesmo assim a utilidade é dubia se não conseguirem reabastecer em vôo? corrigam-me se eu estiver errado mas os F35B não se conseguem reabastecer uns aos outros ou estão preparados para um buddy pod?

Australia Unruffled By F-35 Delays

SYDNEY - Australia's minister for defense, Sen. John Faulkner, is unruffled by the latest cost and schedule difficulties afflicting the Joint Strike Fighter program. And senior defense officials in Canberra say they believe that Australia's plans to acquire up to 100 F-35A Lightning II aircraft aren't much affected by the JSF project's cost overruns.

That's because of budget and schedule buffers built into the Royal Australian Air Force's New Air Combat Capability (NACC) program, which is buying the planes, he said.

A senior defense official in Canberra said March 18 that Australia's budget for the program, and the timing of its orders, are based on the NACC program office's own independent estimates of the JSF program's cost and schedule. These take into account the estimates from the Joint Program Office in Washington and from Lockheed Martin, the JSF's prime contractor, but they include a contingency margin, he said.

So the NACC program office's conservative estimates mean that Australia doesn't really need to take any action or change any of its plans as a result of the JSF program's Nunn-McCurdy breach.

In a March 12 statement, Faulkner stood by the F-35A, calling it the right choice for the RAAF, and saying that it will enable the Australian Defence Force to keep "a strategic air combat capability advantage" until 2030.

"As with all highly complex and cutting-edge projects, risks are to be expected," Faulkner said. "The Australian government's staged acquisition strategy for the JSF includes significant cost and schedule buffers to deal with project risks which will ensure initial operational capability in 2018 is met."

The F-35s will replace the RAAF's 24 F-111C strike aircraft, which are due to retire at the end of this year, and its 71 "classic" F/A-18 Hornet fighters.

Sources declined to discuss the purchasing plans of other JSF partner nations. But a senior official said that if a partner nation withdraws from the JSF production program, it can't count on maintaining its existing workshare in the project, and the other partners would be very unhappy at the prospect of other nations enjoying the industry benefits of the JSF program without actually buying the aircraft themselves.

In November, Australia became the first of the eight JSF partner nations to order the warplane, announcing a 3.2 billion Australian dollar ($2.9 billion) purchase of 14 F-35As, along with initial training and support infrastructure. These are the first of 72 aircraft the RAAF plans to purchase under a combined Phase 2A and 2B of the NACC project, code-named Air 6000.

Those first 14 jets will be delivered beginning in 2014, with 10 remaining in the United States for training and operational testing and four F-35s scheduled to reach Australia in 2017. The RAAF plans to declare Initial Operational Capability (IOC) in 2018, and its third squadron will be operational in 2020-21.

"Approval of the next batch of aircraft and all necessary support and enabling capabilities, sufficient to establish three operational squadrons, will be considered in 2012," said Faulkner's deputy, Greg Combet, the defense materiel, personnel and science minister.

On March 18, Combet told students and faculty at Australia's Centre for Defence and Strategic Studies, at the Australian Defence College in Canberra, "This will fulfill our [2009 Defence] white paper commitment to acquire three operational squadrons comprising not fewer than 72 aircraft."

According to senior RAAF sources, Phase 2C of Project Air 6000 will acquire the balance of the F-35s, bringing the total up to 100. Funding approval for this is scheduled for the latter part of the next decade.

However, the RAAF's original schedule for Project Air 6000 stated an IOC of 2015. On that basis, the service's "classic" F/A-18 Hornets, which recently have been upgraded, were scheduled to retire by 2018.

Last year, a program to replace their center fuselage sections was cancelled at a saving of some 400 million Australian dollars because the aircraft had sufficient service life remaining until 2018. But if they are now required to serve a further two years, some of them may require a center barrel replacement to ensure their structural integrity.

Meanwhile, as a hedge against delays in the JSF program in 2007, Australia's then-defense minister, Brendan Nelson, announced a 6 billion Australian dollar order for 24 F/A-18F Super Hornets. The first four of the two-seat warplanes are due to arrive at the RAAF's Amberley base, near Brisbane, at the end of this month, where they will replace the service's aging F-111C strike aircraft.

The Super Hornets are intended to serve for 10 years before being sold back to the U.S. Navy, replaced in turn by the final batch of F-35s under Phase 2C of Project Air 6000.
