This post has become a meeting place for people who worked there and some recent comments have come in so we’ve updated the post. Its also a popular post to view in Hong Kong and China as a whole.
a lovely item on RAF ATC overseas in the 1950s, from John Douglas…..
RAF Sek Kong was the home of 28 Sqdn flying Vampires, converting to Venoms in 1956.
All take offs to the west and landings to the east – surrounded on 3 sides by hills, with Tai Mo Shan at I think 3000 feet plus to the east. Aircraft were homed to overhead Victoria Peak on Hong Kong Island by Kai Tak Approach, then transferred to Sek Kong ‘Zippy’ ( army search radar on loan!)*. Eventually the army radar was supplemented by an ARAA final approach aid, and eventually superseded by Decca 424.For a single squadron ATC was well endowed!
My final thoughts centre on the ARAA (aerodrome radar approach aid) not easy to operate via a directional aerial controlled in the manner of a submarines periscope, an A scope, and with QDM readings taken from a compass rose, and interpreted for a centre line final approach. …………………..

and John has now sent in article on 28 Squadron RAF that also some material on ATC procedures at Sek Kong.
SK1 landing and aerodrome charts
SK2 the Control Tower and Met Office
SK3 Local Control
SK4 ACR7/Decca 424
SK5 Cpl Hook “at work”.
SK6 Cpl Hook again “hard at work”. The Zippy army radar is in the background (the chequerboard caravan).
*Not as unusual as it may seem. Early RAF fighter control radars going operational in December 1940 were adapted from Army mobile radar units designed to support gunnery. The Army radar unit at Christchurch, part of the Air Defence Experimental Establishment, were involved in the development of several mobile RAF radars during 1939-45. Look at the Antrobus post on this site to see a similar radar being used by RN and Civil ATC in the UK.
The ARAA radar is, we’re assuming, a military equivalent of the ECHO radar used by some civil ATC units, see the EGMC posting on this site. – atchistory
