In 1964 the station was designated and prepared as an operational conversion unit for the expected deployment of the planned TSR-2 (Tactical Strike and Reconnaissance)aircraft. But when the TSR-2 programme was cancelled by the Labour Government of Harold Wilson in 1965, RAF Hemswell had a brief existence as a sub site of 7 School of Recruit Training whose headquarters were at RAF Swinderby. Recruit training continued from Hemswell but the station was eventually placed on "Care and Maintenance" in 1967, when it was decided that all future recruit training would be carried out at RAF Swinderby.
