The USS Tripoli was chosen as the test ship due to the fact that it is optimized for aviation capability with a larger hangar and more aviation facilities space compared to other Wasp class amphibious assault ships. The Tripoli and its sister ship, USS America were built without a well deck and have smaller medical spaces so they can operate more aircraft like the F-35B. The third ship in the America class, USS Boungainville, will have a well-deck, bringing back the surface connector capability.

Now, a new update revealed that Canberra intends to spend a whopping AUD14.6 billion ($10.87 billion) to operate its Lockheed Martin F-35A Lightning II fleet till 2053.

On 6 April, Air Vice-Marshal Leon Phillips, head of the Aerospace Systems Division, told members of the Australian parliament’s Foreign Affairs, Defense and Trade Legislation Committee that a range of variables might push costs up beyond 2032.

rom 2015 to June 30, 2021, the Australian Department of Defense (DoD) has spent AUD623 million on maintaining the fleet of 48 aircraft. The cost of budget allocation for 2021–22 was AUD314 million, according to AVM Phillips.

Les Austaliens n'apprécient pas la facture de la maintenance de leur F-35

Donc en 2021-2222 cela fait 6,5 millions de dollars australien par appareil par an ou 4,8 millions de dollars us par avion

Alors que le nombre d'heures de vol annuelles est en diminution

Un avion c'est fait pour voler. Si ca reste au sol, ca peut finir par couter plus cher que de les faires voler.

Dernier rapport du GAO sur le F-35


https://t.co/Cazk9aowyG

The costs of major upgrades to the F-35 fighter are continuing to rise, and repeated delays on critical simulation tests and on a full-rate production decision are increasing the risk the Defense Department buys faulty jets that need to be fixed, a new Government Accountability Office report said.
In Monday’s report, GAO found that the cost of the F-35′s Block 4 modernization effort grew to $15.1 billion in 2021, $741 million more than the estimated cost in 2020.
Much of that increase was due to a $330 million increase in the estimated cost of the Technology Refresh 3 effort, an upgrade to the F-35′s hardware and software that seeks to improve its processing capability, display units and increased memory, GAO said. The development of Tech Refresh 3 has proven to be more complicated than expected, program officials told GAO, and has driven up the price tag.
Another $312 million in cost increases came from modernizing aging test aircraft supporting weapons development, as well as other testing and lab upgrades, the report found. Operational test and evaluation officials told GAO more flight test capacity is needed to ensure several Block 4 capabilities, including weapons integration, work properly.
Multiple problems with software, funding issues that halted software development for eight months in 2021, and the addition of new capabilities has also delayed the delivery of final Block 4 capabilities to 2029, three years later than originally expected.
Lockheed Martin, which builds the F-35, and program officials took several steps to improve its software development, including increased lab testing of software, improved and more consistent monitoring of software development, and lengthening the schedule for developing Block 4 software “drops” from six to 12 months, beginning in 2022.
This longer software development timetable would make it easier to fix bugs, manage upcoming work schedules and ease the testing backlog that developed under the six-month schedule, program officials told GAO.
But GAO said it remains to be seen whether these changes will improve how Block 4 is rolled out.
The report noted the year-long software development period is a step away from the “agile” software development process of upgrades being delivered in chunks, rather than large quantities of changes dropping all at once, after a lengthy development period.
And test officials with the government told GAO that shifting to a 12-month software drop schedule won’t fix the problem of late deliveries if the program office keeps adding surprise changes. A longer time between software upgrades also means patches for bugs found in the field might take longer to deliver, GAO said.

GAO also raised concerns about the continued delay of the Joint Simulation Environment test, without which the Pentagon can’t wrap up the F-35′s initial operational test and evaluation process and make a decision on full-rate production.
The military is acquiring up to 152 F-35s each year for the Air Force, Navy and Marine Corps — which GAO noted is nearly the full production rate — and is on track to have 1,115 fighters delivered in 2023. If the full-rate production decision occurs that year, GAO said, that will mean about one-third of the total number of F-35s expected to be bought will have been delivered before it finishes operational testing.
This puts the program at risk of more cost overruns, GAO said, if additional performance issues are identified after large numbers of fighters are in the field.
The COVID-19 pandemic has also worsened ongoing supply chain issues and caused labor disruptions, which led to delays in the delivery of F-35s, the report said. The program office and contractors decided in September 2021 to adjust delivery schedules of aircraft through 2023 to absorb the blow from COVID-19. This meant 35 fighters of 120 delivered in 2020 were no longer considered to be late.
But the report also dinged engine contractor Pratt & Whitney for delivering “nearly all” F-35 engines late in 2021. Only six of the 152 engines delivered by Pratt & Whitney were on time, the report said, its lowest number in at least five years.
This was due to quality issues — such as some raw materials being manufactured incorrectly — and not due to COVID-related problems, at least since February 2021.

The F-35 program office wants $500 million so that it can harness technical data that will make it easier for the military services to manage F-35 spare parts instead of having to rely on prime contractor Lockheed Martin, the Pentagon’s F-35 program executive said today.
In order for the Air Force, Marine Corps and Navy to set up an organic supply chain, the services need “provisioning and cataloging data” associated with various parts, Lt. Gen. Eric Fick told lawmakers at a House Armed Services readiness subcommittee hearing.
“We have the rights to that data. It’s not a matter of data rights, it’s matter of data delivery — and being able to have that data delivered is going to cost money,” he said. “And that money is going to be somewhere in the neighborhood of about half a billion dollars, divided amongst the services.”
Fick said the Pentagon has “struggled” to find funding that would allow that data delivery to happen en masse, and is instead working with the individual manufacturers of various components to try to secure that data “at low or no cost.”

In a statement to Breaking Defense, Lockheed Martin spokeswoman Heidi Fields said the company provides all required data rights to the government as contractually required.

Oui, enfin, à la même époque que le Mirage III, les US avaient vendu plus de 5.000 Phantom...c'est plutôt à ça qu'il faudra comparer la production du F-35 !

Un de mes Anciens qui avait séjourné chez McDonnell m'a dit qu'au moment de la guerre du Vietnam, le Phantom était produit à cadence 57 ...

... par mois, hein, pas par an !

Le F-35 fait encore petite bite à côté...
