At St Mawgan there was some input from the Sonobuoy bay. We had antennas on the roof of the bay which we attached 15053 or 15054 buoys too, as and when we got a phone call about stage 2 or was that something else !!!
Ahhhggghhh Too long ago to remember.
There was also some semi permenant buoys in the Bristol channel. They were serviced via the MCU at Pembroke Docks.
