Which airport has the ICAO code KBAD?

The airport with the ICAO code KBAD is Barksdale Air Force Base in Louisiana. This designation is consistent with the ICAO coding system, which assigns specific four-letter codes to airports and airfields globally. The prefix "KB" indicates a location in the United States, and the "AD" portion is unique to Barksdale AFB.
