In 1967, the Air Force began searching for a base that could handle the training for its strategic airlift fleet, the C-141 Starlifter and its newest and largest transport aircraft, the C-5 Galaxy. Again, Oklahoma proved to be well suited for the mission. The Military Airlift Command (MAC) assumed command of the base from SAC and activated the 443d Military Airlift Wing (443 MAW), Training, to assume host wing responsibilities and to fly alongside the SAC aircraft that would become a tenant command at Altus.
