The Air Force is preparing Nellis Air Force Base in Nevada to host an aggressor squadron flying F-35 stealth fighters.
The Air Force in May 2019 announced it would re-establish a defunct squadron that flew F-15s to simulate the enemy force in realistic war games. The service in 2014 shuttered the 65th Aggressor Squadron as a cost-saving measure.
The 65th Aggressor Squadron in its new form would operate nine early-model F-35A stealth fighters that the Air Force considers unsuitable for combat. The "red air" F-35s would help the Air Force to copy the tactics of Russian and Chinese squadrons respectively flying Su-57 and J-20 stealth fighters."
