RAF Humbertson, UK
RAF Humberston is located on the north east coast of Lincolnshire and was one of the Chain Home Low (CHL) which was the name of a British early warning radar system operated by the RAF during World War II. The name refers to CHL’s ability to detect aircraft flying at altitudes below the capabilities of the original Chain Home radars, where most CHL radars were co-located. CHL could reliably detect aircraft flying as low as 500 feet (150 m). The official name was AMES Type 2, referring to the Air Ministry Experimental Station at Bawdsey Manor where it was developed, but this name was almost never used in practice.
