KGRK is the ICAO code for Killeen Regional Airport / Robert Gray Army Airfield (IATA GRK), located in Fort Cavazos, TX.
Killeen Regional Airport is a small military/commercial joint-use airport that operates alongside Robert Gray Army Airfield. The airport is based inside the south end of the Fort Hood Military Reservation, six nautical miles southwest of the central business district of Killeen, Texas, in unincorporated Bell County. The commercial side replaced the old Killeen Municipal Airport in August, 2004 as that airport was unable to expand. Formerly Killeen–Fort Hood Regional Airport, on 26 September, 2023, the airport began the multi-month process of renaming to "Killeen Regional Airport", as approved by the Killeen City Council.
