Thats not counting the ex-Argentine Oerlikon/Skyguard equipped sans at Waddington - at least 7ntil the ammunition time expired.
Didn't the Radar then become a "speed trap" for low flying aircraft, to be used after any public complaints?
Found it
The ex-Argentine Skyguard/35mm cannon combination was used as part of the air-defence system at RAF Waddington for a number of years until retirement. The Skyguard was then found a new use with the RAF Police and the low-level flying monitoring team. A lot of the captured kit is on display in various units here in the Falklands.
