After the war, the aerodrome served various squadrons and units including No. 13 Operational Training Unit (OTU), No. 2 Air Navigation School, No. 4 Flight Training School, and squadrons that used Meteors, Hunters, Javelins and Lightnings.
The RAF left the station in 1964, but the aerodrome was reopened in 1966 as a civil airport. The airfield was named Teesside International Airport in the 1960s, and was renamed Durham Tees Valley Airport in 2004. In 1986 the entire RAF Middleton St George Married Quarter housing estate was sold to The Welbeck Estate Group.
