Two F-35As and two F-15Cs wait at the end of the runway at RAF Lakenheath prior to a training sortie. Airmen from the 388th and 419th Fighter Wings at Hill Air Force Base, Utah, deployed the F-35A overseas for the first time. While in Europe, they will train with units from the U.S. Air Force, Royal Air Force and air forces from other NATO allies. (U.S. Air Force photo/Micah Garbarino)
