The primary units assigned to the base are branch offices of the European Office of Aerospace Research and Development; the Office of Naval Research Global, the Naval Criminal Investigative Service, the Joint NATO National Support Element, and the Defense Energy Support Center and the Fleet Industrial Supply Center.

It administratively falls under the direction of the 422d Air Base Group based out of RAF Croughton, but consists of a collection of multiple Field Operating Agencies and Direct Reporting Units.

It was on long term lease to the United States Navy until 30 September 2007.[1] Control was passed to the United States Air Force on 1 October 2007. The facility was transferred to the United States Air Force for administrative purposes after the disestablishment of the Commander U.S. Naval Activities, United Kingdom.

Current statusEdit

The base has recently undergone renovation; it is planned for personnel from the U.S. Navy, U.S. Army, and U.S. Air Force to be stationed there, alongside civilian staff and contractors.[2] The base also houses a small number of Canadian Forces personnel.[3]

RAF Blenheim Crescent has no RAF personnel present, and is commanded by an officer of the U.S. Air Force at the rank of colonel.[4]
