"The impact will not be felt only by aviators. Owning the sky is the first prerequisite of the way we fight wars today. Air supremacy is what enables us to send an elaborate fleet of machinery caterwauling over a targeted nation, such as Afghanistan or Iraq: the orchestrating AWACS ("Airborne Warning and Control System," the flying surveillance-and-command center); precision bombers; attack planes, helicopters, and drones; ground support; rescue choppers; and the great flying tankers that keep them all fueled. This aerial juggernaut enables modern ground-fighting tactics that rely on the rapid movement of relatively small units, because lightly armed, fast-moving forces can quickly summon devastating air support if they encounter a heavy threat. Wounded soldiers can count on speedy evacuation and sophisticated emergency medical care. Accomplishing all this with anything like the efficiency American forces have enjoyed since the Vietnam War depends on owning the sky, which means having air-to-air hunter-killers that can shoot down enemy planes and destroy surface-to-air missile (SAM) sites before the rest of the fleet takes to the sky. Superior fighters are the linchpin of our modern war tactics. Having owned the high ground for so long, we tend to forget that it is not a birthright.
"Unless the 21st century is the first in human history to somehow transcend geopolitical strife, our military will face severe tests in the coming years. The United States will be expected to take the lead in any showdown against a sophisticated air force. So it is worth examining the nature of air-to-air combat today, and the possible consequences of not building a full fleet of F-22s..."
