Adak Airport is a state-owned public-use airport located west of Adak, on Adak Island in the Aleutian Islands in the U.S. state of Alaska. The airport is the farthest western airfield with scheduled passenger air service in the entire United States at 176.64W.
Adak's airport is one of the largest and most sophisticated airports in the Aleutian Islands. Built by the U.S. Navy for Naval air transport, the airport is a world-class facility consisting of a runway and a runway (perm closed fall 2015), equipped with an Instrument Landing System and glideslope which facilitate Instrument Flight Rules landings.

The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a "general aviation" facility (the "commercial service" category requires at least 2,500 enplanements per year).
History.
The military first developed an air station on Adak during World War II. Adak Army Airfield was used during the Aleutian Campaign by both USAAF and Naval Air units, particularly in defensive actions against Japanese forces occupying Attu and Kiska.
Following the war, the AAF turned Adak over to the United States Air Force until 1950, and then to the Navy who established anti-submarine warfare base there. Adak was most recently run by the U.S. Navy as a deployment base for P-3 Orion maritime patrol aircraft, primarily to conduct antisubmarine warfare operations against submarines and surveillance of naval surface vessels of the former Soviet Union. As many as 5,000 US personnel lived at the base during the Cold War, many with families.
Adak was also used as a refueling stop for transpacific passenger flights. Pan Am first operated a Seattle-Adak-Tokyo flight in 1946 to demonstrate the viability of a transpacific great circle route to the United Nations Relief and Rehabilitation Administration.
On 31 March 1997, the Navy closed Adak Naval Air Facility. A large portion of the former military facility's property was transferred to the Aleut Corporation in 2004 and became a National Wildlife Refuge.

Reeve Aleutian Airways (RAA) served Adak from the late 1940s until 2000 when the airline ceased all flight operations and went out of business. In 1948, Reeve Aleutian was operating Douglas DC-3 service once a week between Anchorage and the airport. From the 1970s through the early 1980s, the airline was operating nonstop service several times a week from Adak to Anchorage (ANC) with Lockheed L-188 Electra turboprop aircraft. Reeve Aleutian also operated nonstop Electra propjet service from the airport to Attu Island during the 1970s. Jet service arrived during the mid 1980s with Reeve Aleutian operating Boeing 727-100 jetliners from the airport nonstop to Anchorage twice a week. By 1989, the airline was operating nonstop 727 service three times a week from Adak to Anchorage. In 1994, Reeve Aleutian was operating four direct flights a week between the airport and Anchorage with Boeing 727-100 jets configured for combi aircraft passenger/freight operations with all of these flights making intermediate stop in each direction at the Cold Bay Airport in the Aleutian Islands.
