821st Combat Support Group Ellsworth AFB, SD

The 821st Combat Support Group was activated at Ellsworth Air Force Base, South Dakota, in February 1964. Its primary mission was to provide essential base support functions for the 821st Strategic Aerospace Division and tenant units, ensuring operational readiness of the base’s strategic bomber and missile forces during the Cold War. The group managed security, logistics, civil engineering, and personnel services, playing a crucial role in sustaining SAC operations at Ellsworth. In 1972, the 821st Combat Support Group was inactivated as part of an Air Force-wide organizational realignment.
