Adak Airport (IATA: ADK, ICAO: PADK) is a public airport located on Adak Island in the Aleutian Islands of Alaska, United States. It serves the small community of Adak, one of the westernmost populated places in the United States, situated roughly 1,200 miles southwest of Anchorage. The airport was originally constructed as a U.S. Navy military facility during World War II and later expanded during the Cold War as part of Naval Air Station Adak. Following the closure of the naval station in 1997, the airport was transferred to civilian use and is now managed by the Aleut Corporation and local authorities. Due to its extreme remoteness and small population, the airport sees very limited commercial air service, with flights primarily connecting Adak to Anchorage. Weather conditions in the Aleutians, including frequent fog, high winds, and precipitation, present significant operational challenges.
