Port Heiden Airport (IATA: PTH, ICAO: PAPH, FAA LID: PTH) is a state-owned public-use airport located six nautical miles (7 mi, 11 km) northeast of the central business district of Port Heiden, in the Lake and Peninsula Borough of the U.S. state of Alaska. Scheduled airline service to King Salmon Airport is provided by Peninsula Airways (PenAir).As per Federal Aviation Administration records, the airport had 919 passenger boardings (enplanements) in calendar year 2008, 964 enplanements in 2009, and 1,037 in 2010. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation facility (the commercial service category requires at least 2,500 enplanements per year).
Originally opened as Fort Morrow Army Airfield, the facility was closed after World War II and returned to civilian status. Beginning in 1958 the airport was used to support Port Heiden Air Force Station, a Cold War United States Air Force Distant Early Warning Line radar station. The station was operated by Detachment 5, 714th Aircraft Control and Warning Squadron based at Cold Bay Air Force Station, near Cold Bay. The radar station was inactivated in September 1969, ending military use of the airport.
The Air Force remediated the radar site around 2000, removing all abandoned military structures and returning the site to a natural condition.
