RAF Kilchiaran was a Royal Air Force radar station situated on the Isle of Islay in Scotland.[1] It was originally active from 1940-1945. In 1954, the base was refurbished to accommodate the RAF Kilchiaran Chain Home Extra Low (CHEL) radar station, which was obsolete by 1958. Since 1958, RAF has not used any of the facilities and BT Group has acquired a few buildings that are now microwave transmission stations.
