The United States Air Force (AF) maintains approximately 30% surplus infrastructure capacity across its airbase enterprise, but it lacks comprehensive strategic basing guidance to objectively evaluate and manage the excess. The excess infrastructure taxes critical fiscal resources and limits the AF’s ability to effectively maintain and keep its installations relevant. The AF recently published its 30-year strategic path in, “America’s Air Force: A Call to the Future,” and it articulates a strategy to emphasizing capability over capacity. The AF should take the same strategic approach of capability over capacity toward installation management and develop basing guidance framed by this strategy. Such guidance will allow the AF to efficiently manage its installations, objectively assess and articulate its excess capacity to its stakeholders, and strategically shape its future basing efforts. This paper provides recommendations for developing strategic basing guidance to align installation capability and capacity to air, space, and cyber mission generation.
