Adversaries search relentlessly for affordable, low-tech ways to counter U.S. military might, and joint doctrine needs to adapt to ensure that low-density/high-value assets are protected in proportion to their value to national security. For instance, no single service or functional component has clear accountability for securing joint aerial approach and departure corridors, leaving aircraft vulnerable to surface-to-air missile threats. A revision of the Air Base Defense Considerations section in Joint Publication 3–10 could provide the sort of guidance that publication gives for sea facilities in its Seaport Facility Defense Considerations section and close a crucial doctrinal seam. It would help ensure ongoing availability of strategic airpower capabilities and protect costly resources in a fiscally austere environment.
