4789th Air Base Group

The 4789th Air Base Group was a United States Air Force unit activated in the early 1950s during the height of the Cold War. Stationed at Ernest Harmon Air Force Base in Newfoundland, Canada, the group was responsible for managing base operations, support services, and logistical functions vital to Strategic Air Command (SAC) bomber missions. It played a key role in maintaining readiness for the deployment and refueling of SAC aircraft as part of North America's early warning and deterrence network. The group was inactivated in the late 1950s as military priorities shifted and base operations were reorganized.
