re: F-35 Joint Strike Fighter Thread
a moment ago I found what had been recently released about the testing:
Posted on InsideDefense.com: June 13, 2014
The Joint Strike Fighter carrier variant will begin its first at-sea testing period in October aboard the aircraft carrier Nimitz (CVN-68) and Lockheed Martin is assisting the Navy in preparing for this test event, according to a company executive.
Lorraine Martin, F-35 executive vice president and general manager for Lockheed Martin, told reporters June 9 during the company's annual media day in Arlington, VA, the testing will be off the coast of San Diego and will last a couple weeks.
Flight testing for the F-35C takes place at Naval Air Station Patuxent River, MD. Martin said most of the testing is focused on the arresting hook and catapult to get ready for tests aboard the Nimitz.
"We're enabling the aircraft to get really hard landings, funny landings, high winds, whatever we can come up with to put it through as much stress . . . on the ground before we go to the aircraft carrier," Martin said.
When the aircraft deploys there will be hundreds of employees that travel with it, including Lockheed Martin employees, she said.
On May 27, an F-35C completed a landing at its maximum sink speed to test the jet's landing gear, airframe and arrestment system at NAS Patuxent River.
"Five sorties were conducted, building up the maximum sink rate test condition of 21.4 feet per second, which represents the maximum sink speed planned for this test," J.D. McFarlan, vice president of F-35 test and verification for Lockheed Martin, said in a company statement. During the tests, the F-35C did three arrestments, several touch-and-goes and one "bolter." The landings were to demonstrate structural readiness for arrested landings on an aircraft carrier at sea.
Air Force Lt. Gen. Christopher Bogdan, joint program executive officer for F-35, told reporters June 12 during a teleconference that the Block 3F software, the software the Navy will use to declare the aircraft operational, is six months behind schedule.
"I have to do everything I can to work with Lockheed to make sure we take that six months and move it back so that we don't impact anything in the future," he said.
In March, Inside the Navy reported that software challenges threatened to delay the Navy's initial operational capability schedule. Bogdan told reporters after a House Armed Services tactical air and land subcommittee hearing that the Navy is at risk of experiencing a three- to four-month delay in declaring IOC.
The Navy expects to declare the F-35C operational in August 2018 with the full Block 3F software suite. That means a full suite of weapons, data links and sensor integration and a full flight envelope.

re: F-35 Joint Strike Fighter Thread
But it is an absolutely standard thing and fairly minor. A prudent action based on the single incident where the pilot landed safely with no issue after a warning light came on.
What they did was simply insist at the start of the weekend that the engines be checked...and it was a straight forward check.
So, this was issued on Friday, June 13th, and by the evening of June 14th 102 of 104 aircraft had been cleared...and I believe one of the aircraft was the one mentioned.
I tell you, the people who naysay this aircraft sometimes are so transparent. They are trumpeting this very minor event as "another in a long list of failings" for the aircraft. Implying, for instance in the UK, that now the UK really ought to question whether they should go ahead with the deal.
Hogwash and poppeycock!
A lot of naysaying and hyperbole going on about this.

On Concurrency Costs:
First I'll retype here two sentences from the DoD document mentioned below: "Concurrency is defined as the overlap in the development and production phases of an acquisition program. Concurrency introduces the risk that aircraft built in early production lots will require modification due to discoveries made during qualification, flight and ground tests, or as a result of engineering analysis."
Posted on InsideDefense.com: June 16, 2014
The F-35 Joint Strike Fighter's concurrency cost estimates have dropped slightly since 2013, from $1.7 billion to $1.6 billion, according to a report obtained this week by InsideDefense.com.
The report, published in April, attributes the slight drop to the resolution of issues the F-35 joint program office forecasted the program would face in low-rate initial production Lots 4-6 as well as efforts by prime contractor Lockheed Martin to quickly introduce production line changes, reducing the number of necessary concurrency modifications. However, the report also projects a slight increase in forecasted concurrency issues in LRIP Lots 7-9 due to some rescheduled tests that have pushed earlier issues into later years.
The F-35 program office is required to submit to Congress regular reports on its estimates of the total cost of concurrency modifications. Such upgrades are often required due to issues that crop up during aircraft qualification or flight and ground testing. Because the F-35 program is simultaneously designing, developing, testing, producing, fielding and sustaining the aircraft, concurrency has become a high-profile and expensive concern.
The report, which does not track total program costs, covers both known concurrency issues as well as forecasted concerns and combines the two to predict total concurrency costs for the program.
"While all forecasted issues may not occur, some un-forecasted issues are likely to arise during testing," the report states. "As changes become known the discrete costs of these changes accrue and become a liability to the program. The aggregate liabilities represented in known and forecasted issues, rather than actual outlays of funding, provide a better descriptor of the impact of concurrency to the F-35 program."
Earlier reports projected wider gaps between known and forecasted concurrency issues. In the first report, submitted in 2012, the program office pegged total concurrency costs at $2.5 billion, with $2.1 billion of that estimate based on projections. In 2013, the total estimated cost dropped to $1.7 billion, with projected issues making up about 60 percent of the total cost. This year, close to $1 billion of the $1.6 billion estimate is based on known issues. The office expects that as the program moves forward and officials gain a better handle on concurrency issues, the gap will diminish greatly.
"The F-35 JPO anticipates that known costs will converge toward the total projected estimate until development has completed," the report notes. "Estimates will be reviewed and updated on an annual basis; these will contain adjustments as a result of retiring, realizing, rescheduling, or adding changes as the program progresses."
The report says a big reason for the reduction in expected total concurrency costs since 2012 is Lockheed's push to implement a joint concurrency management system, which allows changes to the production line to be made more quickly, reducing the number of aircraft needing upgrades in the future. The JPO used the system to incorporate a change to the cockpit display's electronic unit, preventing the need for the future retrofit of 62 aircraft.
"The system records meaningful information on the status and progression of discovered technical issues and change requests," the report notes. "It includes monthly delivery of metrics to demonstrate change incorporation process improvement over the remainder of the program, and it tracks all change requests in both production incorporation and retrofit modification."
Estimated cost reductions are also attributed to contracting mechanisms that split concurrency costs evenly between Lockheed and the government in LRIP Lots 6 and 7, according to the report.

Is there a way you could post the whole article? I couldn't log in (as required by WSJ).
Thanks.
