Pentagon vows fixes for major F-35 issues

The Pentagon has agreed to resolve major technical deficienci­es with the F-35 Joint Strike Fighter before moving ahead with full-rate production, according to the Government Accountabi­lity Office.

Wright-Patterson Air Force Base has a large stake in the future of the jet as a contender to manage the Air Force version of the F-35, congressio­nal lawmakers have said.

The watchdog agency had warned the Defense Department should not launch fullscale production of the most expensive weapons program in history, in a recently issued report, until “critical deficienci­es” with the stealth fighter jet were resolved, GAO con

cluded. The plane has nearly 1,000 reported deficienci­es, and nearly 200 would not be resolved before full-rate production, the report said.

“The F-35 is going to have a very long life, a lot of upgrades, and a lot of money,” said Richard Aboulafia, an aerospace analyst with the Virginia-based Teal Group. “Really, this is about the schedule. And even then it’s not really clear how much of a mean-

ingful delay this will be.”

The fighter, which has been in developmen­t for 17 years and has battled tech- nical and cost overruns, is developed under the Joint Program Office in Crystal City, Va., with oversight cur- rently of the three versions of the stealth jet.

GAO found the F-35 has not met reliabilit­y and maintainab­ility targets and testing would take longer than expected next year. The Defense Department has been expected to make a decision on full-rate pro- duction of the F-35 in Octo- ber 2019, even as the program faced critical deficien- cies, the watchdog agency said.

GAO recommende­d Congress should avoid appropriat­ing money for the latest upgraded version of the plane until the Defense Department “provides a sound business case for the effort.”

The Joint Program Office concurred with the recommenda­tions, GAO said.

The F-35 program will cost an estimated $406 billion in acquisitio­n costs and $1.1 trillion in operations over the next 60 years.

The report raised renewed questions about the F-35’s affordabil­ity in the decades ahead with competing ex p enses for programs like the KC-46 aerial tanker and the Navy’s new Colum- bia-class ballistic missile submarine.

The Pentagon has pushed to find ways to lower costs to avoid cuts to future F-35 purchases.

Identified technical issues included six cases of pilots reporting physiologi­cal symptoms of oxygen deprivatio­n, which did not discover a common cause, between May and August 2017 and 21 cases of fuel hoses breaking off during aerial refueling of the Marine Corps and Navy versions of the F-35 between April 2014 and August 2017, GAO said.

The Defense Department has plans to buy 2,456 of the jets, including the F-35A, the Air Force land-based variant; the F-35B, a Marine Corps vertical takeoff and landing jet; and the F-35C, a carrier-based version.

The Marine Corps declared the jet operationa­l in 2015, while the Air Force declared the plane ready for combat in late 2016. The Navy could later this year.

Lockheed Martin, the prime manufactur­er, has so far delivered more than 260 aircraft to the Defense Department, GAO noted. Many of those early versions have had to be retrofitte­d. Future plans call for deliveries to reach 77 per year in 2019 — although a House committee has reportedly pushed to buy 16 more — and purchases could reach a peak of 105 by 2024 before starting a gradual decrease in 2030.

The Air Force has said it may have to cut its purchase of aircraft by one-third, or about 560 aircraft, if operationa­l costs are not reduced, Bloomberg has reported.

In a statement, Lockheed Martin’s Greg Ulmer, vice president and general manager of the F-35 program, said the issues identified do not impact flight safety or operations, and he added reliabilit­y and availabili­ty of the aircraft have improved.

“The issues identified represent areas where we are collaborat­ing with our customers and industry partners to improve the weapon systems’ performanc­e,” he said. “Lockheed Martin is working closely with the Joint Program Office to prioritize and correct all of these areas to ensure we continue delivering t he most advanced aircraft in the world.” Contact this reporter at 937225-2363 or email Barrie.
