An F-16 Fighting Falcon with a "ghost" paint scheme sits on a ramp at Hill Air Force Base, Utah, June 3, 2020. The 576th Aircraft Maintenance Squadron painted the jet at the request of the 64th Aggressor Squadron at Nellis Air Force Base, Nevada, that participates in training with Air Force and other aviation branches during Red Flag exercises. The paint scheme is intended to replicate an adversary’s fighter jet. United States, allied, and partner-nation aircrews routinely train against accurate and realistic threats including aircraft painted to replicate those pilots might see in aerial combat.
