Nine heavy hitters from the Lockheed Martin F-35 program fronted Tuesday’s media briefing here at Farnborough. But even three senior Pentagon officials, one Air Force general and five industry chiefs could not conjure the actual hardware–although the good news at the show yesterday was that the F-35 was given clearance to fly with “a restricted flight envelope.” The four F-35Bs slated to fly to the UK were have been grounded at NAS Patuxent River after a June 23 engine fire at Eglin AFB in Florida.

F-35 manufacturer Lockheed Martin will retrofit early production lots of F-35Bs delivered to the U.S. Marine Corps with modified bulkheads to address cracking issues that came to light during durability testing of ground articles last fall. It will build redesigned bulkheads into the fighter beginning with low-rate production lot (LRIP) 9, said Rear Adm. Randy Mahr, deputy program manager with the Pentagon’s F-35 joint program office (JPO).

Lockheed Martin’s F-35 Lightning II notched its 10,000th flight hour in September, and by the end of the month the combined Joint Strike Fighter fleet had flown 6,492 times for 10,077 hours. Illustrating the momentum that the program has built since operational production aircraft began training operations, more than half the total was amassed in the past 11 months. It had previously taken the program six years to reach the 5,000-hour milestone.

Lockheed Martin and the U.S. Department of Defense (DOD) reached an agreement in principle to fund the next two low-rate initial production (LRIP) lots of the F-35 Joint Strike Fighter, comprising 71 aircraft. The company and DOD jointly announced the “handshake agreement” on July 30 in advance of signing the LRIP contracts, which will provide consecutive, 4-percent reductions in the unit cost of U.S. military variants, they said. The parties said they will release cost details when the contracts are finalized.

F-35 engine manufacturer Pratt & Whitney has started sustainment planning for the aircraft’s F135 turbofan even as F-35s continue flight-testing. “The F135 program is in an interesting place,” Bennett Croswell, Pratt & Whitney Military Engines president, said at a Paris Air Show press briefing on June 19. “We’re in all three phases of the lifecycle of the program. We are still in development; we are producing F135 engines; and now we are in sustainment as well.”
