Vastrap Airport (ICAO: FAVS) is a restricted military airfield located near Upington in the Northern Cape province of South Africa. It is associated with the Vastrap weapons testing range, a facility historically used by the South African National Defence Force (SANDF) for missile and weapons system trials. The airfield is not open to regular commercial traffic and has no scheduled passenger services. Its primary function is to support defence-related operations and testing activities in the remote semi-arid landscape of the Northern Cape.
