Rotor System, around 300 bunkers around the UK and umpteen squadrons.
Once we switched to Tripwire that was scaled back to just enough to cover the V force bases whilst they flushed and QRA under Linesman/Mediator.
Under Linesman there were 3 planned T85 radar sites - Neatishead, Staxton Wold and Boulmer feeding to the sole dual ATC & ADGE site at West Drayton. (Mediator was the ATC half)
During the transition they kept the island sites at Saxa & Benbecula along the CRCs at Buchan, Boulmer and Patrington.
Then Tripwire changed to Flexible Response and we needed a survivable ADGE again. So the above ground R30 building was built at Neatishead to replace Patrington which shut and, after a nearly 15 year delay, the UKADGE programme began to put in new radars and harden the bunkers.
Which is why for 20 years through the heart of the Cold War the entire UKAD ground environment was run from 3 prefab above ground Ops buildings…..
