The Curtis E. LeMay Center for Doctrine Development and Education (LeMay Center), with headquarters at Maxwell Air Force Base, Alabama, was a Direct Reporting Unit (DRU) to the Chief of Staff of the United States Air Force. The unit, formerly known as the Air Force Doctrine Center (AFDC), was established on 24 February 1997 as a DRU, and is the single voice for all doctrinal matters within the United States Air Force and to the joint community. AFDC was inactivated and its mission merged with the College for Aerospace Doctrine, Research and Education Center to form the LeMay Center under Air University in 2007.
