Marcianise Airfield is an abandoned World War II military airfield in southeast Italy, which is located approximately 10 km north-northwest of Marcianise in the province of Caserta, Campania; about 32 km north-northwest of Naples. Built in 1943 by United States Army Engineers, the airfield was a large facility capable of handling heavy bombers built for Fifteenth Air Force, which stationed B-17s at the field after the war, prior to their return to the United States. However its primary use was by Air Technical Service Command and by Twelfth Air Force tactical fighter bomber units during the Italian Campaign. The field was used by the senior command of the Mediterranean Theater of Operations based at the Royal Palace of Caserta through 1947.
