NATO agreed to pay for the HAS build/hardening of the UK airfields as long as the UK provided SAW cover. So the old RAFG/Cyprus Bloodhound were put in place at Bawdsey, West Raynham etc and Rapier units to cover those outside their cover such as LM, KS, BZ etc. No computer links, such at Gata, were ever put in place with the UKADGE units, and in fact for most of their existence the HMEZ/LMEZ were not even updated on the the radar maps.
IIRC Within 6 months of NATO signing the cheques for the hardening programme the Boodhound force was disbanded.
Thats not counting the ex-Argentine Oerlikon/Skyguard equipped sqns at Waddington - at least until the ammunition time expired.
