These capabilities also make it possible for an air and space force to find and hit an adversary's strategic centers of gravity directly, while also operating at the operational and tactical levels of war. What has changed very subtly over the last few years is that information systems have become strategic centers of gravity. Although I talk about what air and space forces do, this is not the same as saying you can do everything with air power. Both now and in the future, warfare will require contributions from all the services. But as the nation's air and space experts, the Air Force has the responsibility for providing national leaders air and space options for defending our nation and its interests around the world.
People talk about the fact that there are four air forces in America.
There are not four air forces. There is one Air Force in America. There are services that have air arms, but that's not their primary reason for existing. The Air Force has as its primary reason for existing, providing air and space forces to this country. That's all we do.
