A U.S. Air Force KC-10 Extender from the 2nd Air Refueling Squadron (2nd ARS) stationed at Joint Base McGuire-Dix-Lakehurst, New Jersey, conducts refueling operations with an F/A-18 Hornet during a refueling training exercise as part of Talisman Sabre 2015 near Darwin, Australia, July 15, 2015. U.S. and Australian forces are conducting air refueling missions throughout the Talisman Sabre 2015 exercise to improve interoperability and familiarization with each other's procedures. Talisman Sabre is a biennial exercise that provides an invaluable opportunity for nearly 30,000 U.S. and Australian defense forces to conduct operations in a combined, joint and interagency environment that will increase both countries’ ability to plan and execute a full range of operations from combat missions to humanitarian assistance efforts.
