Barking Sands Airport (IATA: BKH, ICAO: PHBK) is a military airfield located at the Pacific Missile Range Facility (PMRF) near Kekaha on the western coast of Kauai, Hawaii. It is operated by the United States Navy and serves primarily as a support facility for missile testing, unmanned aerial systems, and military training exercises. The airport is not a commercial passenger facility, though it can accommodate civilian charter and inter-island flights under certain conditions. Its remote location on the Mana Plain provides access to vast Pacific Ocean test ranges, making it strategically important for naval and joint military operations.
