In 1986 an underground Control and Reporting Post (CRP) was built as part of the new UKADGE (United Kingdom Air Defence and Ground Environment) project. New mobile, Marconi Electronic Systems manufactured, radar systems, including a S723 Martello (RAF Type 91), and telecommunication installations were added during the mid-1980s. In the late nineties, the installation became remote operation. Portreath's parent station was RAF St. Mawgan for administration but data was routed to RAF Neatishead.
