Patch of the 423rd ABS

The 423 ABG began life as the 423rd Air Base Squadron when it was activated on 12 July 1995 at RAF Molesworth. The 423 ABS replaced the inactivated 710th Air Base Wing, briefly active at Alconbury to replace the 10th Air Base Wing, which had moved to Colorado on 1 November 1994. Exactly 10 years later, the 423rd ABS was reorganized as the 423rd Air Base Group. This was part of a larger reorganization of many geographically separated units within the United Kingdom as components of the 501st Combat Support Wing also located at RAF Alconbury. At this time, 423 ABG headquarters officially moved to RAF Alconbury.

In 2012, the group included around 400 personnel, including about 277 active duty military, 140 Department of Defense civilians and 170 Non-Appropriated Fund employees, as well as 255 Ministry of Defence employees.[3]


The group is organized into a group staff and six squadrons. The squadrons include the 423rd Communications Squadron, 423rd Medical Squadron (initiated 2007),[4] 423rd Security Forces Squadron, 423rd Force Support Squadron, and 423rd Civil Engineer Squadron. The 426th Air Base Squadron is also under the 423rd Air Base Group but is geographically separated and physically located at Stavanger Air Base, Norway.[3]
