Air Force Grounds $400 Billion F-35s Because of 'Peeling and Crumbling' Insulation (washingtonpost.com)

An anonymous Slashdot reader quotes the Washington Post: Less than two months after declaring the controversial F-35 Joint Strike Fighter ready for combat, the Air Force on Friday announced that it was temporarily grounding 15 of the jets after it discovered that insulation was "peeling and crumbling" inside the fuel tanks. The setback is the latest for the $400 billion system, the most expensive in the history of the Pentagon. The problem comes as the program, which for years faced billions of dollars in cost overruns and significant schedule delays, had begun to make strides.

The insulation problem affects a total of 57 aircraft, the Air Force said, 42 of which are still in production... In a statement, Lockheed Martin said that "the issue is confined to one supplier source and one batch of parts." It emphasized that "this is not a technical or design issue; it is a supply chain manufacturing quality issue..." It is unclear how long the aircraft would be grounded, how long the problem would take to fix or what the larger affect on the program would be.

âoeWhile nearing completion, the F-35 is still in development, and challenges are to be expected," said an Air Force spokeswoman, adding "The F-35 program has a proven track record of solving issues as they arise, and we're confident we'll continue to do so."

    I hate the f-35, waste of money. But... that's a little bit disingenuous.

    Modern fighter jets are not rated solely on speed and manoeuvrability. Range, ceiling, avionics, weapons and all the rest are what make it a proper piece of kit. Dogfighting is low on the list of priorities in 2016.

    The Russians are laughing all right, but this is way down the list. I bet invading the Ukraine with almost no repercussions has them grinning widely. Trump expressing his willingness to ditch NATO probably has probably garnered a few giggles as well.

    A modern Tomahawk cruise missile has an inventory cost of around $750,000. Once you use it, you have to replace it at full cost.

    An F-35A's flight cost is around $40,000 per flight hour (google exactly what a flight hour is) and is expected to fall to around $30,000/fh in due course.

    A 5 hour mission designed to hit 5 targets means 5 Tomahawk missiles expended, at a cost of $3.75million for the mission.

    The same mission for the F-35A would cost, currently, $200,000 in flight hours, and $135,000 for 5 Mk.82 bombs with JDAM kits - a total mission cost of $335,000.

    The mission cost difference is a saving of about $3.4Million, give or take.

    So, with a current purchase cost of $98Million for a LRIP (low rate initial production) F-35A, it would only need to fly 30 or so missions to be worth while, over the cost of continually buying expendable cruise missiles to carry out the same missions.

    How does that work out in real life?

    During the second Gulf War air campaign, there were 20,753 combat sorties by coalition aircraft, during which they used 18,467 smart bombs and 9,251 dumb bombs.

    That war, if fought by using cruise missiles solely, would set you back $20.8Billion just to replace your expended ordnance.

    Take the aircraft costs out of the equation for a moment - replacing all those expended munitions with JDAMs would cost $748Million, leaving a balance of more than $20Billion to cover the operating costs of the aircraft...

    You could buy a fleet of 100 F-35s and operate them for just under half their entire projected life on the balance alone...
