The 15 AF returned to a combat-ready role as a result of the 1948 Berlin Crisis, a squadron from the 301st Bombardment Group was deployed with its B-29s at Fürstenfeldbruck Air Base, Germany. SAC immediately ordered the group's other two squadrons to Goose Bay Air Base, Labrador to prepare for immediate deployment to Germany. The 307th and 28th Bombardment Groups were placed on alert and ordered to be ready to deploy within three and twelve hours respectively. Within a few weeks, the other 301st Bomb Group's squadrons had joined the first. Later on 28 July, Bombardment Group left Rapid City AFB, South Dakota for RAF Scampton, in the United Kingdom. The 307th Bombardment Group left MacDill AFB, Florida for RAF Marham and RAF Waddington in the UK.
