In 1969, the Military Aircraft Command and the Military Airlift Wing received the first C-5 aircraft.

Lockheed produced an American military transport aircraft designed to provide strategic heavy airlift over intercontinental distances and to carry outsize and oversize cargo. The C-5 also known as the Galaxy has been operated by the United States Air Force and known to be one of the largest military aircraft in the world and one of the most reliable in carrying combat equipments to any destination around the globe.

During the first years in service, a number of Galaxy were stationed at Altus AFB, Oklahoma, Dover AFB, Delaware, and Travis AFB, California serving as cargo planes at high altitude traveling at long hauls. Eventually, these aircrafts were transferred to the Air Force Reserve, Stewart Air National Guard Base and Westover Air Reserve Base.
