Britain’s new aircraft carrier is now afloat, but the total forecast cost of £6.1 billion ($10.4 billion) still threatens to sink other defense projects in the UK. To this cost must be added the forecast near-£2.5 billion ($4.28 billion) being contributed by the UK to development and initial test and evaluation of the F-35s that will fly from her decks, plus perhaps another £5 billion ($8.56 billion) for their production. However, the Royal Navy and the Ministry of Defence (MoD) are taking their cue from H.M.
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).
The premier position of the UK aerospace industry on the Lockheed Martin F-35 program was highlighted by a briefing and presentation at the Defence Security and Equipment International (DSEI) show in London this week. Some 500 British companies are involved in producing “15 percent of each of the 3,100 F-35s that will be built,” according to Steve O’Bryan, vice president for F-35 program integration at Lockheed Martin. The company has calculated that the program will secure 24,000 high-technology jobs in the UK through 2039.
The U.S. military cleared the F-35B short takeoff/vertical landing (Stovl) variant of the Joint Strike Fighter to resume flight operations last week, ending a grounding of more than three weeks that was ordered after a fuel line failed in a test aircraft at Eglin Air Force Base, Fla.
An “improperly crimped” fueldraulics line is the probable cause of a fuel leak that led the U.S. military to suspend flight operations of the F-35B short takeoff/vertical landing (Stovl) variant of the Joint Strike Fighter, which was grounded on January 18.
Flight operations of the F-35B short takeoff/vertical landing (Stovl) variant of the Joint Strike Fighter remained suspended this week as U.S. military and contractor engineering teams investigated the cause of an engine fueldraulic line failure in a test aircraft at Eglin Air Force Base, Fla. The fueldraulic line is part of the fuel-based hydraulic system that controls the actuators of the F-35B’s vectoring exhaust system. The grounding did not affect the F-35A and C models, respectively, the conventional takeoff and carrier variants.
After protracted negotiations, Lockheed Martin reached an agreement in principle with the Pentagon for the fifth lot of low-rate initial production F-35s (LRIP-5). The company has reported new flight-test milestones for the Lightning II stealth fighter in recent weeks. But there was less good news from Canada, which is reconsidering its commitment to the F-35 on cost grounds.
Flight-testing of the Lockheed Martin F-35 is ahead of the 2012 plan, and software development is making up lost ground, now standing at two months behind schedule. Steve O’Bryan, Lockheed Martin’s v-p for F-35 program integration and business development, told a meeting in London sponsored by The Air League that the F-35B STOVL version that the UK will buy is 40 percent ahead on flights and test points. Of the nine million lines of software code in the aircraft, 87 percent is now in flight test, with another 6 percent in laboratory tests.
Denmark’s Terma is showing off, for the first time here at the show, the multi-mission pod (MMP) it has developed for the Lockheed Martin F-35 Joint Strike Fighter. The MMP began life as the gun pod for the F-35, which Terma designed and developed on behalf of General Dynamics Armament and Technical Products, but the company has developed it into a more versatile pod that should prove attractive, in particular, to overseas operators of the JSF.
“We live in a goldfish bowl,” sighed Lockheed Martin F-35 vice president customer engagement Steve O’Bryan. Speaking in London last March, he was referring to the stream of official reports, testimonies and comments that examine the Joint Strike Fighter program. This year alone, five major documents on the F-35 have reached the public domain. In January, a Pentagon operational test and evaluation report surfaced.
