Chepstow racecourse was a Satellite Landing Ground (SLG) for aircraft from 19 Maintenance Unit (19 MU) based at St Athan from 3 May 1941. Shields were made of wire wool and netting to protect and camouflage the aircraft, but these were replaced in 1942 by bays created by clearing areas within the surrounding woodland. Some of the original racecourse buildings were used by personnel. Of the waritme buidlings, the Watch Office (now an abandoned residence) and walls that once formed the latrine block are still extant

The racecourse was given the designation 7 Satellite Landing Ground (SLG) and protected by local Home Guard reinforced from time to time with available army units.
