I didn't know the Mount Davis site was used by the military after WW2, so it was interesting to hear from Norman Lawson that he'd been at RAF Mount Davis in 1956-7. He writes:
After about a year [at Cape D'Aguilar], we were posted to Mount Davis, where I served out the remainder of my National Service.
Both Cap D'ag and Mt. Davis were Radar stations. CD for fighter control (I was in Fighter Command/FEAF) whilst [Mt. Davis] was surveillance. We tracked the Migs from Peking (as was) towards HK before they turned around.
We must have done this hundreds of times! A fairly pointless exercise, as it was generally acknowledged that our aging Vampires and Meteors would hardly be off the Kai Tak runway if they came all the way!
It looks as though the site may have closed shortly after Norman left. If you scroll to the bottom of this page, there's a description (and photos of "Project Cabbage Leaf" in 1957-58. It was to build "a new radar station at Tai Mo Shan in the New Territories of Hong Kong to replace the aging Mount Davis radar on Hong Kong Island."
Ther's another brief description of the site by Allan Pitcairns:
RAF Mount Davis was a Radar installation in the 1950s. It was built on the site of a pre WW2 gun emplacement which was destroyed by the Japanese at the beginning of the war. I served there as a Radar Operator from 1955 till early 1957. The station tracked all inbound and outbound civilian and military aircraft and provided ground control for fighter squadrons based at Kai Tak. The station's aging Type 14 Radar was replaced in 1956 by new GEC equipment which had greater range and capability. It was part of 117 Signals Unit which was based at Kai Tak.
Allan's note that new equipment was installed in 1956 doesn't match with the Cabbage Leaf description of the 'aging Mount Davis radar'. Maybe they are talking about two different pieces of equipment?
Does anyone know whan RAF Mount Davis closed?
