British Military Aviation in 1997

January
The Royal Air Force (RAF) station at Sek Kong in the New Territories, Hong Kong, closes. The Royal Air Force's last remaining base in Asia, Sek Kong had been home to No.28 Squadron (Westland Wessex), the last RAF flying squadron in the Far East. With the closure of the station, No.28 Squadron transfers to Hong Kong's civil airport at Kai Tak.

1 April
The Royal Air Force Volunteer Reserve (RAFVR) and the Royal Auxiliary Air Force (RAuxAF) are combined into a single reserve force, in line with the Reserve Forces Act. This is accomplished by disbanding the RAFVR, after 60 years of service, and integrating members into the RAuxAF.

1 April
The Operations Support Branch is established to bring together the existing air traffic control, fighter control, intelligence and RAF Regiment specialisations. Additionally, a fifth specialisation, flight operations, is created within the Operations Support Branch to provide trained officers to undertake support duties, previously carried out in operations centres and headquarters by aircrew officers on ground tours.

10 April
The Defence Helicopter Flying School (DHFS) is officially opened at RAF Shawbury by Air Chief Marshal Sir John Willis, Vice-Chief of the Defence Staff. The DHFS absorbs the flying training element of No.2 Flying Training School at Shawbury, which disbanded on 1 April 1997, and the Search and Rescue Training School at RAF Valley. The Royal Air Force component of the DHFS is subsequently designated No.60 (Reserve) Squadron.

Air Chief Marshal Sir Richard Johns is appointed to the post of Chief of the Air Staff.
