RAF Edzel was home to the US Navy security group’s Oceanographic Monitoring Station, monitoring the North Sea and the coast around the north of Britain. It worked in conjunction with the former ROTOR site at Inverbervie which had also been taken over by the US Navy in 1960. The hub of the base was the massive receiver building which had two levels below ground. This would have relayed information to the computer and communications centre.
The base closed in 1996, the domestic site has been sold and the housing reused. The airfield site is still secure with no evidence of any demolition. Site visits are inadvisable.
