Location of Piombino Airfield, Italy

It was an all-weather temporary field built by the United States Army Air Force XII Engineer Command using a graded earth compacted surface, with a prefabricated hessian (burlap) surfacing known as PHS. PHS was made of an asphalt-impregnated jute which was rolled out over the compacted surface over a square mesh track (SMT) grid of wire joined in 3-inch squares. Pierced Steel Planking was also used for parking areas, as well as for dispersal sites, when it was available. In addition, tents were used for billeting and also for support facilities; an access road was built to the existing road infrastructure; a dump for supplies, ammunition, and gasoline drums, along with a drinkable water and minimal electrical grid for communications and station lighting.

Once completed it was turned over for use by the Twelfth Air Force 417th Night Fighter Squadron between 23 July-5 August 1944, flying Bristol Beaufighters.

When the Americans pulled out the airfield was dismantled by engineers. Today the location of the airfield is undetermined due to the large amount of urban growth in the area.
