90 (Signals) Group on 24 April 1946 under the administrative control of British Air Forces of Occupation and Transport Command.

The primary role of 444 SU was to act as a ground station for the Skynet (satellite) communications system.

The Royal Air Force had received responsibility for operating the Skynet system in the late 1960s under the Rationalisation of Inter Services Telecommunications (RISTACOM) agreement.

This was to prove short-lived, however, for on 1 November 1973, 444 SU and the unit responsible for maintaining the Skynet ground station at RAF Gan – No.

Subsequently, with the disbandment of HQ NEAF on 31 March 1976, control of RAF Hong Kong and its component units were transferred in total to Strike Command.
