Ukraine won’t get a basic F-16 capability until at least 2024, and developing proficiency with that aircraft “could be four or five years down the road,” Gen. James B. Hecker, commander of U.S. Air Forces Europe and Air Forces-Africa, said Aug. 18. Hecker also downplayed the significance the F-16s may have in helping Ukraine combat Russia’s invasion, saying the capability won’t be a “silver bullet.”
