F-35 Stealth Fighter Still Has 419 ‘Deficiencies,’ Manager Says

The head of the U.S. Defense Department’s F-35 program said the number of “deficiencies” in the stealth fighter jet’s hardware and software is decreasing but that hundreds of technical challenges remain.

Speaking to reporters last week in his offices in Arlington, Virginia, Air Force Lt. Gen. Christopher Bogdan discussed a range of issues affecting the Pentagon’s biggest weapons program at nearly $400 billion, including the hundreds of lingering deficiency reports, or DRs, known as “technical debt” in acquisition parlance.

“There are 419 things that we have yet to decide with the war fighters how we’re going to fix them, whether we’re going to fix them and when we’re going to fix them,” he said. The figure was three times higher a few years ago and “we think the technical debt that we have — the deficiencies that we have — are things that we can handle … within the next two years,” he said.
