The depot at Hill AFB, Utah, has now worked on all three variants of the F-35, the first facility to do so. A Navy F-35C landed April 15 for modifications at the Ogden Air Logistics Complex. The facility first received an F-35A in Sept. 2013, and has worked on four F-35B models, according to a Hill release. The F-35C, which came from the training center at Eglin AFB, Fla., arrived for structural upgrades, low-observable restoration, and system modifications, the release states. The jet will stay at the complex through September.
A semi-autonomous Collaborative Combat Aircraft drone shot down an air-to-air target in a Dec. 8 test supported by the U.S. Air Force, a notable milestone in the development of the loyal wingman-type drones that will join the fleets of the USAF, other American services, and allies and adversaries.
