Lockheed Martin has confirmed to Flight International that the F-35 Joint Strike Fighter continues to exceed its weight target after a fourth bottom-up review of the structural design. The technical data is still being analysed, but the early results "showed we did not achieve the objectives we expected of the structural weight of the airplane at this point in the programme", says Lockheed Martin. Programme officials are studying alternatives to weight reduction measures, such as boosting in-flight performance and production schedules.
