Shetland Day 1 - RAF Noss Hill
In the evening (still on the first day of my Shetland residency), I had the opportunity to visit nearby RAF Noss Hill, an Air Ministry Experimental Station (AMES) No 54 [1].
Gordon Carle on his blog post about Noss Hill from ‘A History of Saxa Vord’ (which is an amazing source of information, including many military sites across Shetland) describes how radar cover was expanded in the Northern Isles following the German invasion of Denmark and Norway in April 1940. “At the beginning of WWII the UKs Chain Home RDF system stretched along the south and east coasts of England and up the east coast of Scotland. However, the most northerly station was at Netherbutton, near Kirkwall, in Orkney and the equipment there was designed to look primarily to the south-east.” Radar was a relatively new technology, and as war progressed, new and existing radar sites had to be flexible to meet new needs.
Part of the response in 1940 was to build two permanent sites, one at Noss Hill and one at Lambaness, in the north of Unst. Whilst work was carried out on the more substantial Final Chain Home equipment which took time to build, both Noss Hill and Lambaness would become temporarily operational as Advance Chain Home (ACH) stations, which were smaller, and quicker and simpler to construct.
At Noss Hill, I found the remains of both systems, including aerial towers, Transmitter and Receiver/Ops blocks, and a ‘Standby Set House’ which would have contained back-up diesel generators, and various other constructions. The photographs below are mainly from the Transmitter and Receiver/Ops blocks.
