If the United States goes to war tomorrow, its Air Force will fly and fight as the world’s best. No longer can the Air Force rely on Bagram-style air bases as sanctuaries, thanks to anti-access and area-denial capabilities developed by China and others. During World War II, Gen. Pete Quesada and the 9th Air Force brought expeditionary practices to the European theater. These capabilities are complementary—One Force Design enables sequenced operations and the ability to field a single lethal Air Force. Lt. Gen. David A. Harris is deputy chief of staff for Air Force Futures of the U.S. Air Force.
