RIAT: The F-35’s international debut here at RIAT isn’t just about NATO, Russia, China and other threats. It’s also about the Air Force’s future as Gen. Frank Gorenc, commander of US Air Forces Europe, knows.

His son, Lt. Col. Stephen Nichols, was one of the F-35A pilots who deployed to Mountain Home Air Force Base for a crucial exercise where the planes demonstrated their ability to maintain a high mission capable rate and deadly accuracy dropping bombs and using other weapons. “Basically, I’m living vicariously through him,” Gorenc told an audience of several dozen allied representatives, press and industry from the United States and Britain.
