Passage:By 1968 regular air force military airlift squadrons were operating the Lockheed C-141 Starlifter, while reserve heavy airlift units still flew the obsolete Douglas C-124 Globemaster II. As the Globemaster was retired, Air Force Reserve formed associate units with the C-141. In this program reserve units flew and maintained aircraft owned by an associated regular unit. On 25 March 1968, the 730th moved to Norton Air Force Base without aircraft as an associate of the active duty 63d Military Airlift Wing. In 1973, Air Force Reserve inactivated its reserve associate groups and the squadron was assigned directly to the 445th Military Airlift Wing. Missions the 730th has flown included humanitarian relief, aeromedical flights, and airdrops of supplies and paratroopers.
