During the late 1920s it was decided that the RAF needed to be modernised and expanded to meet expected future demands. Subsequently, Hucknall was identified for expansion into an RAF station and was bought by the Air Ministry in the latter part of 1927. This period is commonly known as the '1930s expansion period' and many aerodromes were reopened or upgraded during this time. The Nottingham Aero Club vacated the aerodrome during 1928 before the formation of No. 504 (County of Nottingham) Squadron and the official RAF opening. A large proportion of the buildings from 1916 and the expansion period are still extant, including the C.1916 General Service Sheds, which are listed buildings under English Heritage monument number 1398209.
