Grombalia Airfield is an abandoned World War II military airfield in Tunisia, which is located approximately east-southeast of Hammam-Lif, about southeast of Tunis. It was a temporary airfield constructed by Army Engineers using Pierced Steel Planking (PSP) for its runway, parking and dispersal areas, not designed for heavy aircraft or for long term use. It was used by the United States Army Air Force Twelfth Air Force 82d Fighter Group during the North African Campaign, flying P-38 Lightnings from the airfield between August and October 1943.
