Squadron on 1 October. The year 1959 saw the disbanding of No. 21 Squadron (15 January) and No. 50 Squadron (1 October). On 31 December 1960 No. 76 Squadron disbanded. The final flying unit No. 35 Squadron was disbanded on 11 September 1961. With the disbanding of No. 35 Squadron Upwood was transferred to RAF Strike Command who quickly set about transforming the airfield into a hub of various support activities. Over the next several months the station became home to No 4 Ground Radio Servicing Section, Radio Technical Publications Squadron, the Aeromedical Training Centre, the Joint School of Photographic Interpretation and three squadrons of HQ No 33 Field Wing, RAF Regiment. The different units had barely settled in when change came again. In early 1963 the RAF Regiment units departed. In 1964 the other units left as well, leaving Upwood with only a token care-taker staff.
