Royal Air Force Molesworth or more simply RAF Molesworth is a Royal Air Force station located near Molesworth, Cambridgeshire, England with a history dating back to 1917. Its runway and flight line facilities were closed in 1973 and demolished. New facilities were constructed to support ground-launched cruise missile operations in the early 1980s. It was one of the two British bases to house cruise missiles and a focus for protests. It is now a non-flying facility under the control of the United States Air Force (USAF), and is one of two Royal Air Force (RAF) stations in Cambridgeshire currently used by the United States Air Forces in Europe (USAFE). Molesworth, RAF Alconbury and RAF Upwood were considered the "Tri-Base Area" due to their close geographic proximity and interdependency unti
