Remains of RAF Bempton Centrimetric Early Warning (CEW) ROTOR station

Chain Home / AMES TYPE 1 (Air Ministry Experimental Station) was the codename for the ring of coastal radar stations built by the British before and during World War II. The system comprised two types of radar: the metre-wave Chain Home stations which provided long-range early warning, and the centimetre-wave Chain Home Low / AMES TYPE 2 stations, which were shorter-ranged but could detect aircraft flying at low level.
