Wasn't RAF Bishops Court in NI a radar station? One of the few miitary places I never went to over there.Towards the end of the Cold War an air threat to the UK was identified that Blackjack and Backfire aircraft cold fly out to the west, turn over the Atlantic and attack UK targets on the home run from the west not the east as would have been expected. They would of course in most cases fly over RoI. An RAF radar was established at Ty Croes in North Wales I think to cover the gap in the radar picture, it was removed soon after the Cold War endex. No doubt the rader could return and together with RAF Portreath give coverage over all RoI ?
