The international defense industry fair (IDEF 13) held in Istanbul, Turkey, from May 7 to 10 saw the Turkish industry announce a number of developments. The most notable was the revelation of three potential concepts for the TF-X national combat aircraft program, a stealthy aircraft that is ultimately expected to replace the F-16.

The Obama administration has proposed a $526.6 billion defense budget for Fiscal Year 2014 that continues funding for developmental priorities, including the F-35 Joint Strike Fighter, the KC-46A tanker and a future long-range bomber. The President’s base defense budget does not include funding for overseas contingency operations in Afghanistan and does not reflect budget cuts mandated by sequestration.

Operational testing and evaluation of the F-35A has begun, with the delivery of four aircraft to Nellis AFB. They were accepted by the U.S. Air Force Warfare Center in a ceremony on March 19. Eight more F-35As will join them by 2019. The Air Force has now received 24 F-35A conventional takeoff and landing aircraft. Another 34 F-35s have been delivered to the U.S. Marine Corps and U.S. Navy.

The U.S. Defense Advanced Research Projects Agency (Darpa) is soliciting proposals from industry for a vertical takeoff and landing experimental aircraft (VTOL X-plane) that would demonstrate “radical” improvements over the current state of VTOL flight. In late February, Darpa issued a broad agency announcement seeking proposals by May 1.

The U.S. military grounded its fleet of Lockheed Martin F-35 Joint Strike Fighters after a routine engine inspection revealed a cracked turbine blade in an F-35A based at Edwards Air Force Base, Calif. The precautionary flight suspension was announced on February 22, following an inspection earlier in the week. The grounding affects all three variants of the fighter, for a total of 51 aircraft.

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.
