The U.S. Air Force's F-35A made its debut at the toughest Red Flag yet, and not only dominated the air space but made the legacy aircraft in the force package even deadlier, according to pilots.

The F-35's participation in the Air Force's capstone training event at Nellis AFB, Nevada, which is known as one of the world's most realistic and challenging air-to-air combat exercises, marked a crucial test for the fifth-generation fighter. This year, pilots went up against the most aggressive threat laydown ever seen at a Red Flag: more surface-to-air missiles (SAMs), more jamming, and more red air, said Lt. Col. George Watkins, 34th Fighter Squadron commander.
