The ANGRC traces its roots to the Vietnam War, during which the Air Guard provided airlift support to American forces in Southeast Asia. By 1972, growing global Air Guard responsibilities led to the establishment of the Air National Guard Air Operations Center (AOC) IN 1974. In an effort to ensure a separation of operational activities between the ANG and NGB staff, the ANG Support Center was created on Andrews AFB, Maryland in 1976. In 1992 the ANG Support Center was re-designated as the Air National Guard Readiness Center (ANGRC).
