​​During the Second World War, the airfield was used as a training facility for numerous units. It eventually had three grass runways and a total of 18 small hangars for aircraft. From 1942, the airfield served as a relief landing ground for various flying training squadrons. It eventually closed in 1957, after flying training switched to jet aircraft, for which Harlaxton’s grass runways were not suitable.

​The land has since been returned to agricultural use, and very little remains of the former airfield.
